根據(jù)業(yè)主未來的生產規(guī)劃及特點，其廢氣適宜于采用濃縮+燃燒系統(tǒng)進行處理，而對于業(yè)主的間歇式生產特點，燃燒系統(tǒng)適宜選用催化燃燒方式（CO），但濃縮段工藝有沸石及活性碳濃縮兩種，對于選用何種方式現(xiàn)做出如下對比：
According to the owner’s future production plan and characteristics, the exhaust gas is suitable for treatment with a concentration and combustion system. For the owner’s intermittent production characteristics, the combustion system is suitable for Catalytic Oxidizer (CO), however the concentration selections includes zeolite and activated carbon. the following comparison are made for decision.

安全性
Safety
沸石本身為不可燃，正常運行情況下不會出現(xiàn)燃燒情況。
Zeolite is non-flammable and will not burn under normal operating conditions.
活性碳本身為可燃物，并且活性碳在吸附有機物質時還會產生吸附熱，如果碳層或者氣流不均勻，將會造成局部溫度急劇升高點燃活性碳從而造成連鎖燃燒；另外脫附過程中如果升溫過快也會造成燃燒。
The activated carbon is combustible, and the activated carbon will also generate adsorption heat in adsorbing organic substances. If the carbon layer or the air flow is not uniform, it will cause the partial temperature rising sharply to ignite the activated carbon and result in chain combustion. In addition, during the desorption process, If the temperature rises too fast, it will also get burning.

由于活性碳如果脫附風量過小，容易造成散熱不佳，影響系統(tǒng)安全性，所以濃縮倍率無法提升
If the desorption air volume of activated carbon is too small, it is easy to cause poor heat dissipation and infulence the safety of the system, so the concentration rate cannot be increased.

系統(tǒng)運行穩(wěn)定性
System operation stability
沸石濃縮+燃燒系統(tǒng)無需切換管道，可以通過PLC控制，并且根據(jù)各點位的溫度監(jiān)控，實時調節(jié)風量配比，達到最穩(wěn)定、節(jié)能的運行狀態(tài)
The zeolite concentration and combustion system does not need to switch pipelines, and can be controlled by PLC, and according to the temperature monitoring of each point, the air volume ratio can be adjusted in real time to achieve the most stable and energy-saving operation state
活性碳濃縮+燃燒系統(tǒng)使用多個活性碳吸附器并聯(lián)，定時切換吸脫附管，需使用大量切換閥門，而且脫附時間長，需要系統(tǒng)長時間保持運行狀態(tài)，否則容易出現(xiàn)脫附不完全造成吸附效果不達標。
The activated carbon concentration and combustion system uses multiple activated carbon adsorbers in parallel. Switching the adsorption and desorption pipes regularly, requires a large number of switching valves, and long desorption time. The system needs to be kept in operation for a long time, otherwise it is easy to cause incomplete desorption and result in the adsorption effect not up to standard.

沸石材料使用壽命一般在5~7年
The service life of zeolite materials is generally 5 to 7 years
活性碳顆粒由于本身強度，在使用過程中不可避免的會出現(xiàn)摩擦破碎，造成損失，并且由于脫附過程中會存在死區(qū)，所以整體壽命一般不會超過1年。
Due to the strength of activated carbon particles, friction and breakage will inevitably occur during use and causing losses. Because there will be dead zones in the desorption process, the overall life span generally does not exceed 1 year.
預處理過濾器均為每季度更換一次
The pretreatment filter is replaced every quarter
系統(tǒng)維護
system maintenance
沸石裝置更換簡便，只需1~2人即可完成，每1~2年可以對沸石進行采樣檢測，確認沸石劣化情況，若有需要，可以進行再生作業(yè)，保證使用壽命。
The zeolite device is easy to be ?replaced and can be completed by just 1 or 2 person. The zeolite must be sampled and tested every 1 or 2 years to confirm the deterioration of the zeolite. If necessary, regeneration can be carried out to ensure the service life.
如果出現(xiàn)局部沸石材料損壞可以快速修復，不會影響生產。
If partial zeolite material damage occurs, it can be repaired quickly without stopping production.
活性碳更換工作量大，每次需要更換13噸左右活性碳，需要吊車及機械搬運工具輔助，并且容易造成周邊環(huán)境二次污染；更換下來的飽和活性碳為環(huán)保重點管理的危險廢棄物，需要委托專業(yè)單位進行處置，而現(xiàn)在危廢處置單位的處置量有限，可能會出現(xiàn)需要排隊無法及時處置的現(xiàn)象，這種情況下未能及時處置的飽和活性碳需要存放在專用的危廢存放區(qū)。
Activated carbon replacement is a heavy workload, about 13 tons of activated carbon needs to be replaced each time, which requires the assistance of cranes and mechanical handling tools, and is likely to cause secondary pollution to the surrounding environment. the replaced saturated activated carbon is a hazardous waste regulated by environmental protection administration. Professional organizations are entrusted for disposal, and now the disposal capacity of the organization is limited, and there may be a phenomenon that needs to be queued and the waste cannot be disposed in time. In this situation, undisposed saturated activated carbon must be stored in a dedicated hazardous waste storage area.
燃燒裝置運行維護部分基本相同
The operation and maintenance of the combustion device is basically the same
根據(jù)以上比較，從安全可靠、運行穩(wěn)定、節(jié)能、易于維保、占地面積小及無二次污染等方面綜合考慮，沸石濃縮裝置更適合業(yè)主的實際需求，所以我方推薦的處理工藝流程為沸石濃縮+催化燃燒工藝。
Based on the above comparison, considering the safety and reliability, stable operation, energy saving, easy maintenance, small footprint and no secondary pollution, the zeolite concentration device is more suitable for the actual needs of the owner, so the treatment process we recommend is Zeolite concentration and catalytic combustion process.
3.5 濃縮裝置樣式選擇
3.5 Concentration Device Selection
對于本項目風量大、濃度低，需要選用一種吸附穩(wěn)定、濃縮倍率高、性價比良好的吸附材料。
For this project with large air volume and low concentration, it is necessary to select an adsorption material with stable characteristic, high concentration rate and cost-effective.
現(xiàn)在常見的沸石濃縮裝置使用的吸附材料主要有日系和歐美系產品，其中日系產品濃縮倍率高、使用范圍廣，案例多更為符合本項目的需求。
The adsorption materials used in common zeolite concentration devices are mainly made in Japan， Europe and US. Japanese products have a high concentration rate and a wide range of applications. Many cases are in line with the needs of this project.
另外日系沸石濃縮裝置又可以分為轉輪結構及傳統(tǒng)結構兩類，其吸附裝置運行結構、使用的沸石種類均有比較不同的特性，對于本項目使用何種樣式的濃縮裝置更適合業(yè)主的實際需求，先做出一下比較：
In addition, the Japanese zeolite concentration device can be divided into two types: the wheel structure and the traditional structure. The operation structure of the adsorption device and the type of zeolite used have different characteristics.

180~220℃ Because the module contains more substrates, the heat absorbed by the substrate will not play a role in desorption, so more heat is needed. for this reason, the substrate must be cooled after desorption for adsorption stage.
150~180℃由于沸石含量高所以整體熱能利用率高，吸附材料存熱少，所以可以使用較低脫附溫度，并且脫附完成無需冷卻可直接進入吸附階段
150~180℃ Because of the high zeolite content, the overall heat energy utilization rate is high, and the adsorption material has less heat storage, so a lower desorption temperature can be used, and directly get into the adsorption stage without cooling after desorption.

以模塊化吸附單元塊為單元進行更換，無需特殊設備配合，1~2人使用簡單工具即可更換，而且更換速度快，可在生產換班或短時間內完成
In the condition that the modular adsorption unit block is used for replacement, no special equipment is needed, and it can be replaced by 1 or 2 persons with simple tools, and the replacement speed is fast, which can be completed during a production shift or within a short rest.

According to the comparison of the above aspects, the drum type has obvious advantages in concentration ratio, investment cost, operation energy saving, and later maintenance. It is more in line with the needs of this project for high concentration ratio, stable energy saving and easy maintenance.

3.6 有機廢氣沸石轉筒吸附—催化燃燒系統(tǒng)簡介
3.6 Introduction to The Organic Waste Gas Zeolite Drum Adsorption Catalytic Combustion System
根據(jù)業(yè)主有機廢氣的相關參數(shù)及相關的處理要求，我們采用轉輪濃縮+催化燃燒的方式進行處理。
According to the relevant parameters of the owner’s organic waste gas and treatment requirements, we adopt the method of rotary wheel enrichment and catalytic combustion for treatment.
簡易流程如下：
The brief process is as follows:
有機廢氣經管道收集進入前置過濾器過濾和冷凝降溫等設備進行預處理以后，進入沸石轉筒裝置吸附處理區(qū)進行凈化處理，進入濃縮轉筒的有機廢氣（上圖，下同）在常溫下被轉筒吸附區(qū)吸附凈化后直接排放至大氣（最高凈化效率可達95%）（），接著因轉筒的轉動而進入脫附區(qū)，吸附了有機物質的轉筒在脫附區(qū)內被150-180℃小風量脫附（高倍濃縮）、高濃度小風量廢氣（）進入催化燃燒處理系統(tǒng)。
The organic waste gas is collected through the pipeline and enters into the pre-filter and condensation cooling equipment for pretreatment, and then enters into the adsorption treatment zone of the zeolite drum device for purification treatment. The organic waste gas entering the concentration drum (as the above picture and the same as below) to be adsorpted and purified in the drum adsorption zone, then directly discharged to the atmosphere (the highest purification efficiency can reach 95%), ?then enters the desorption zone due to the rotation of the drum. the adsorpting drum will be desorpted by180°C small air volume (high concentration), high concentration and small air volume exhaust gas () enter the catalytic combustion treatment system.
廢氣只要被加熱到280-350℃，進入催化床就能被催化分解成水和二氧化碳后放熱成為高溫清潔氣體（），溫度交換后排入大氣。
As long as the exhaust gas is heated to 280-350℃, it can be catalytically decomposed into water and carbon dioxide when it enters the catalyst bed, it releases heat to become a high-temperature clean gas and is discharged into the atmosphere after temperature exchange.
其中催化燃燒是典型的氣-固相催化反應，其實質是活性氧參與的深度氧化作用。
The catalytic combustion is a typical gas-solid phase catalytic reaction, and the essence is the deep oxidation with active oxygen.
在催化燃燒過程中，催化劑的作用是降低活化能，同時催化劑表面具有吸附作用，使反應物分子富集于表面提高了反應速率，加快了反應的進行。
In the process of catalytic combustion, the role of the catalyst is to reduce the activation energy, at the same time, the surface of the catalyst has an adsorption effect, so that the reactant molecules are concentrated on the surface to increase the reaction rate and accelerate the reaction.
借助催化劑可使有機廢氣在較低的起燃溫度條件下，發(fā)生無焰燃燒，并氧化分解為CO2和H2O，同時放出大量熱能，其反應過程為：
With the help of a catalyst, the organic waste gas can undergo flameless combustion at a lower ignition temperature, and be oxidized and decomposed into CO2 and H2O, meanwhile a large amount of heat energy is released. The reaction process is as follow:

由于開口要求風速較低（不低于0.5m/s），容易受環(huán)境干擾，影響測定精度，因此可通過測量排風總風量推算截面風速方法；c.噴涂機與排風機設計連鎖，當排風機未開啟或排風管道內風速不達標時噴涂機無法開啟。
Since the air outlet requires a low wind speed (no less than 0.5m/s), it is easily affected by environmental interference and disturb the measurement accuracy. Therefore, the cross-sectional wind speed can be calculated by measuring the total exhaust air volume; c. The painter and the exhaust fan are designed to be interlocked, therefore the painter cannot be initiated if the fan is not turned on or the wind speed in the exhaust duct is not up to the standard.

清洗房產生廢水中主要含有灰塵、清洗劑及液壓油等污染物，根據(jù)業(yè)主實際需求及前期溝通，本次通過實驗確認之前提出的廢水循環(huán)使用的可行性并確定設備規(guī)格。
The waste water produced in the Cleaning booth mainly contains pollutants such as dust, cleaning agent and hydraulic oil. According to the actual needs of the owner and the preliminary communication, this experiment confirm the feasibility of the previously proposed waste water recycling and determine the equipment specifications.
4.2.1實驗
4.2.1 Experiment
1.廢水狀態(tài)：本次實驗采用業(yè)主提供的廢水樣品，廢水呈淡黃色、略渾濁（見圖片1）
2.實驗一：使用小型電解實驗裝置對廢水進行電解處理并觀察廢水變化及測試電導率（單位μs/cm），實驗開始30分鐘后，廢水上部出現(xiàn)明顯浮渣，水體開始變白變清，電導率略有上升為22.7（見圖片2）；1小時后浮渣繼續(xù)增加，電導率為42（見圖片3）；2小時后電導率上升至96.9（見圖片4）。
3.實驗二：將電解后的廢水與原始廢水混合，模擬循環(huán)混合狀態(tài)，混合后水體電導率為37.8（見圖片5）；凈化1小時候電導率上升為121.6（見圖片6），凈化后的水體基本無色透明（見圖片7），將中部水體取出靜置后，會有部分絮體沉降產生（見圖片8），水體電導率下降為72.5（見圖片9）。

4.結論：本次實驗中廢水經過電解凈化后，水體變?yōu)闈崈?，大部分廢渣可以上浮，較易去除，而根據(jù)業(yè)主要求處理后水體電導率不能大于500，而此次實驗中最高電導率為121.6，并且靜置一段時間后電導率下降至72.5。
此現(xiàn)象表明實驗中的較高電導率的出現(xiàn)，主要是由于水體中雜質轉化為絮體后，仍有部分較輕的絮體懸浮在水體中；另外由于小型電解裝置并不是實時循環(huán)，雜質去除后仍不停有鋁離子電解進入水體，離子濃度變高造成電解率偏高。
This phenomenon shows that the higher conductivity in the experiment is mainly due to the fact that after the impurities in the water body are converted into flocs, there are still some lighter flocs suspended in the water body. In addition, because the small electrolytic device does not circulate in real time, aluminum ions are still electrolyzed into the water body after the impurities are removed , and higher ion concentration resulting in a higher electrolysis rate.
所以通過靜置后電導率便會下降，實際設備中的循環(huán)水箱即可達到此效果，并且實際設備會不斷有循環(huán)水進入，只需要按照廢水的實際情況設置運行時間便可以保證沒有過多離子進入水體，所以完全可以滿足業(yè)主對于循環(huán)水電導率的要求。
Therefore, the conductivity will drop after staying still, and the circulating water tank in the actual equipment can achieve this effect with continuously entering circulating water. We only need to set the operating time according to the actual situation of the wastewater to ensure that there are no excessive ions enter into the water body, so it can fully meet the requirements of the circulating water conductivity.
4.2.2設計方案
4.2.2 Design Plan
采用廢水循環(huán)利用方式時，前期清洗使用循環(huán)水，最后使用清水進行最后沖洗，沖洗后的廢水作為補充水進入循環(huán)系統(tǒng)，設計循環(huán)系統(tǒng)處理量：5m3/d，由于現(xiàn)場并無現(xiàn)成循環(huán)水池，因此我司設計在該集水池邊再行制作一個3米×4米×1.5米的循環(huán)池，池中分為廢水收集區(qū)及沉降排放池；隨后在該循環(huán)池邊上安裝1臺電解廢水凈化裝置進行處理，處理后的循環(huán)水流入沉降排放池用于下次清洗，并且設置1套壓濾裝置用于去除沉降濾渣，系統(tǒng)處理流程如下：
When the wastewater recycling method is adopted, circulating water is used for pre-cleaning, and clean water is used for final flushing. The rinsed wastewater enters the circulation system as supplementary water. The designed treatment capacity of the circulation system is 5m3/d. Because there is no existing circulating pond on site, so our company designed another 3m×4m×1.5m circulating pond beside the collecting pond. The pond is divided into a waste water collection area and a sedimentation discharge area; then an electrolytic waste water purification device is installed beside the circulating pond for treatment, the treated circulating water flows into the sedimentation discharge pond for the next cleaning, and a filter press device is set to remove the sedimentation filter residue. The system processing flow is as follows:

2.通過上述改造后，循環(huán)水可持續(xù)循環(huán)使用，無需排放。
3.廢水處理機能夠完全替代投加絮凝劑，并且產生的廢渣量較小、自動化程度高，廢渣容易清理。
4.3 廢氣預處理系統(tǒng)
4.3 Exhaust Gas Pretreatment System
4.3.1三級過濾器
4.3.1 Three-stage Filter
油漆廢氣含有較多的顆粒物，廢氣中的顆粒物會在沸石材料表面不斷的堆積、聚集，不斷增加的顆粒物會影響轉筒濃縮裝置的凈化效果，為了保護沸石轉筒的吸附凈化性能，有機廢氣進入濃縮裝置之前必須經過過濾器，考慮到系統(tǒng)的壓力損失以及濃縮轉筒對顆粒物濃度的要求，在沸石轉輪前端設有三級袋式過濾器，過濾等級分別為G4、F7、F9，不同等級過濾器為模塊化設計，組裝方便。
Paint waste gas contains a lot particulates, which will continue to accumulate on the surface of the zeolite material. The increasing particulates will affect the purification effect of the drum concentration device. In order to sustain the adsorption and purification performance of the zeolite drum. Organic waste gas must pass through a filter before entering into the concentration device . Considering the pressure loss of the system and the requirement of the concentration drum for the concentration of particulates, a three-stage bag filter is installed at the front of the zeolite wheel. The filtration grades are G4, F7, F9. The filter adopts a modular design with different grades and easily to be assembled.
在過濾器前后設置壓差計根據(jù)壓差的變化來確定更換周期，保證廢氣處理系統(tǒng)正常、安全、穩(wěn)定運行。
Differential pressure gauges are installed at the front and rear of the filter to determine the replacement cycle according to the change of the pressure difference to ensure the normal, safe and stable operation of the exhaust gas treatment system.

眾所周知沸石材料是整個濃縮裝置的核心， 本設備采用世界最先進沸石轉筒技術和最高效的沸石模塊，作為裝置核心的沸石模塊是由多層沸石紙疊放成蜂窩狀的成型模塊。
As we known that zeolite material is the core of the entire concentration device. This equipment adopts the world’s most advanced zeolite drum technology and the most efficient zeolite module. As the core of the device, the zeolite module is a honeycomb shaped module made of multiple layers of zeolite paper.
這種沸石紙是使用業(yè)界最先進的濕式抄紙法工藝，把粉末狀的沸石和骨骼纖維及粘合劑（有機，無機）制成瓦楞狀紙張(見下圖)。
This zeolite paper uses the industry’s most advanced wet papermaking process to mix powdered zeolite, bone fibers and binders (organic, inorganic) into corrugated paper (see the picture below).
這樣就連骨骼纖維的間隙中都含有沸石，所以紙中含有的沸石總量將會增加，而且還具有很難讓沸石脫落的特性。
In this way, zeolite is contained even in the gaps between the bone fibers, so the total amount of zeolite contained in the paper will increase, and zeolite is hard to fall off.
沸石含量的比率越高，不僅沸石模塊具有更強的吸附脫附有機溶劑，水分等的能力,而且相對于骨骼纖維來說熱容量低的沸石的比率越高，模塊在吸附濃縮系統(tǒng)中的加熱脫附能耗效率會大步提升。
The higher ratio of zeolite content, the zeolite module has stronger ability to adsorb and desorb organic solvents, moisture, etc.Compared with bone fiber, the higher ratio of zeolite with low heat capacity, the heating energy efficiency and desorption of the module get higher in the adsorption concentration system.
沸石模塊的沸石含有率在75~80wt%是世界最高的，所以比第二位（50wt%）的能耗效率提升30%以上。
The zeolite content rate of the zeolite module is the highest in the world with 75~80wt%, so it is more than 30% higher than the No. 2 energy efficiency (50wt%) .
