Description
本創作係為關於一種廢氣處理系統，特別係指一種濕式塗佈排氣回用處理系統，藉由管路連通各單元結構，特別是指利用沸石轉輪淨化經回收之廢氣氣體，再將淨化後之淨化回收氣體回收再利用，因而降低煙囪排放量為原本之6~14%，且減少新鮮空氣的使用達86~94%。The present invention relates to an exhaust gas treatment system, in particular to a wet coating exhaust gas treatment system, which is connected to each unit structure by a pipeline, in particular to purify the recovered exhaust gas by using a zeolite rotary wheel, and then The purified purified gas is recycled and reused, thus reducing the chimney emissions by 6-14%, and reducing the use of fresh air by 86~94%.
按，請參閱第1圖所示，其係為習用排氣處理系統之架構圖，將濕式塗佈供排氣單元100串聯揮發性有機化合物(Volatile Organic Compounds,VOC)處理單元200，傳統方法係為引用室內外之空氣或經特別過濾調整之空氣，導入濕式塗佈供排氣單元100使用，透過空氣的吹送，將於濕式塗佈製程中塗料所具有的揮發性有機化合物引出，再流入揮發性有機化合物(Volatile Organic Compounds,VOC)處理單元200，將廢氣中的揮發性有機化合物吸附淨化及濃縮高溫燃燒淨化後排出至煙囪300，再排放到大氣裡。According to FIG. 1 , which is a structural diagram of a conventional exhaust gas treatment system, a wet coating and exhaust unit 100 is connected in series with a Volatile Organic Compounds (VOC) processing unit 200, a conventional method. The air is quoted as indoor or outdoor air or specially filtered, and is introduced into the wet coating and exhausting unit 100. The air is blown to lead out the volatile organic compounds in the coating during the wet coating process. The Volatile Organic Compounds (VOC) treatment unit 200 is further introduced, and the volatile organic compounds in the exhaust gas are adsorbed and purified, concentrated and burned, and discharged to the chimney 300, and then discharged to the atmosphere.
更進一步說明，新鮮氣體a經由新鮮氣體管路A透過進氣濾網110並經由進氣風機120抽吸導入至加熱裝置130進行加熱，且利用控制閥170調控該新鮮氣體a之流量，並加熱至所需溫度形成進氣氣體b，進氣氣體b經由進氣氣體管路B透過 排氣烘箱150之吹嘴140流入至排氣烘箱150內。接著，藉由回收風機160抽吸出排氣烘箱150內之廢氣氣體c，經由廢氣氣體管路C將廢氣氣體c導入揮發性有機化合物(Volatile Organic Compounds,VOC)處理單元200，將廢氣氣體c吸附淨化及濃縮高溫氧化燃燒淨化，之後將淨化氣體d經淨化氣體管路D連通煙囪300排出。Further, the fresh gas a is sent through the intake filter 110 through the fresh gas line A and is introduced into the heating device 130 via the intake fan 120 for heating, and the flow rate of the fresh gas a is regulated by the control valve 170 and heated. The intake gas b is formed to the required temperature, and the intake gas b is transmitted through the intake gas line B. The mouthpiece 140 of the exhaust oven 150 flows into the exhaust oven 150. Then, the exhaust gas c in the exhaust oven 150 is sucked out by the recovery fan 160, and the exhaust gas c is introduced into the volatile organic compound (VOC) processing unit 200 via the exhaust gas line C, and the exhaust gas c is The adsorption purification and concentration high-temperature oxidation combustion purification, and then the purification gas d is discharged through the purification gas pipeline D to the chimney 300.
然，依上述排氣處理系統說明該煙囪300的排氣量等於濕式塗佈供排氣單元之廢氣氣體c的氣體量；且新鮮空氣a需由經過處理調整後，再行導入濕式塗佈供排氣單元100中，空調負荷甚高；而排出之氣體經由揮發性有機化合物(Volatile Organic Compounds,VOC)處理單元200將揮發性有機化合物去除後，仍有少量的揮發性有機化合物排放至大氣，故現有方式甚是浪費能源與污染環境。However, according to the above exhaust treatment system, the exhaust amount of the chimney 300 is equal to the amount of gas of the exhaust gas c of the wet coating supply and exhaust unit; and the fresh air a needs to be adjusted after processing, and then introduced into the wet coating. In the cloth supply and exhaust unit 100, the air conditioning load is very high; and after the exhausted gas is removed from the volatile organic compound via the Volatile Organic Compounds (VOC) processing unit 200, a small amount of volatile organic compounds are still discharged to The atmosphere is so wasteful of energy and polluting the environment.
由此可見，上述現有方式仍有諸多缺失，實非一良善之設計，而亟待加以改良。It can be seen that there are still many shortcomings in the above existing methods, which is not a good design and needs to be improved.

再請參閱第3圖，係為本創作之濕式塗佈排氣回用處理系統之沸石轉輪之立體圖。如圖所示，該沸石轉輪之吸附區211面積為較大，而該脫附區212及該冷卻區213則為兩個較小且面積相等之處理側。該沸石轉輪之吸附區211面積係為該沸石轉輪210之60%~84%。該沸石轉輪之冷卻區212面積係為該沸石轉輪210之5%~10%。該沸石轉輪之脫附區213面積係為該沸石轉輪210之5%~10%。於實際運用時，該吸附區211、該冷卻區212及該脫附區213之面積比例可依實際情形進行調整，而實際製程該脫附濃縮氣體h排放量由該沸石轉輪210濃縮10~20倍，則該脫附濃縮氣體h排放量為一般流量的1/10~1/20。其中，該沸石轉輪210係由一組電力驅動設備用以旋轉該沸石轉輪210，故該沸石轉輪210轉速運作時為可變速、可控制每小時旋轉2至6轉之能力或定速調整。Referring to Fig. 3 again, it is a perspective view of the zeolite runner of the wet-coating exhaust gas treatment system of the present invention. As shown, the area of the adsorption zone 211 of the zeolite runner is relatively large, and the desorption zone 212 and the cooling zone 213 are two smaller, equal-sized treatment sides. The area of the adsorption zone 211 of the zeolite runner is 60% to 84% of the zeolite runner 210. The area of the cooling zone 212 of the zeolite runner is 5% to 10% of the zeolite runner 210. The area of the desorption zone 213 of the zeolite runner is 5% to 10% of the zeolite runner 210. In actual use, the ratio of the area of the adsorption zone 211, the cooling zone 212 and the desorption zone 213 can be adjusted according to the actual situation, and the actual process of the desorption concentrated gas h emission is concentrated by the zeolite reel 210~ 20 times, the amount of the desorbed concentrated gas h is 1/10 to 1/20 of the general flow rate. Wherein, the zeolite runner 210 is driven by a group of electric drive devices for rotating the zeolite runner 210, so that the speed of the zeolite runner 210 is variable speed, and can control the ability to rotate 2 to 6 revolutions per hour or constant speed. Adjustment.

As shown, the zeolite wheel 210 can further include a heat exchanger 260 through which the cooling gas H is directed back to the desorption zone 213 via a high temperature line. J is connected to the exhaust gas oxidation furnace processing unit 250, and the high-temperature gas j is led out from the exhaust gas oxidation furnace processing unit 250 and introduced into the chimney 300. Further, the heat exchanger 260 is further connected to the purification recovery pipeline G and the high temperature pipeline J, and is connected A control valve is disposed between the purification and recovery pipelines G for regulating the flow rate of the adsorbed purified gas g and the high temperature gas j, thereby adjusting the temperature of the intake gas b as a heat source required for the wet coating process.
本創作係透過各個管路連通各單元裝置，係藉由濕式塗佈供排氣單元將濕式塗佈製程所產生之製程廢氣導入沸石轉輪吸附區淨化，淨化後氣體再帶回濕式塗佈供排氣單元之進氣管路回收使用，不再直接排放至大氣。最終排向大氣之氣體係經沸石轉輪濃縮後，再由廢氣氧化爐處理單元燃燒淨化後排向煙囪，其濃縮後之廢氣量已大幅降低。The creation system connects each unit device through each pipeline, and the process exhaust gas generated by the wet coating process is introduced into the zeolite runner adsorption zone by the wet coating supply and exhaust unit, and the purified gas is brought back to the wet zone. The intake line coated with the exhaust unit is recycled and is no longer directly discharged to the atmosphere. The gas system finally discharged to the atmosphere is concentrated by the zeolite runner, and then burned and purified by the exhaust gas oxidation furnace treatment unit, and then discharged to the chimney, and the concentrated exhaust gas amount has been greatly reduced.
本創作係將經由沸石轉輪之淨化氣體回收帶回濕式塗佈供排氣單元運用，主要為將淨化氣體回收再利用以減少排放氣體流量，並可因回收使用淨化氣體，而減少製程所需之新鮮空氣，進而降低外氣空調箱之負荷，符合環保與節能之雙重目的。The creation department will use the purified gas recovery belt of the zeolite runner to return to the wet coating and supply unit, mainly to recycle and use the purified gas to reduce the flow rate of the exhaust gas, and reduce the process by recycling the purified gas. The need for fresh air, thereby reducing the load on the external air conditioning box, is in line with the dual purpose of environmental protection and energy saving.
