The principle of catalytic combustion treatment.
該技術(shù)采用沸石吸附面積大、不同溫度下分子間作用力不同的原理，經(jīng)催化燃燒后分解VOCS進行設(shè)計。
This technology adopts the principle of large adsorption area of zeolite and different intermolecular forces at different temperatures, and is designed by decomposing VOCS after catalytic combustion.

在低溫下，大風量吸附風機通過濾箱過濾掉車間內(nèi)的揮發(fā)性有機物，然后通過沸石分子篩輪吸附，通過沸石輪吸附的氣體可直接排放。
At low temperatures, the high airflow adsorption fan filters out volatile organic compounds in the workshop through a filter box, and then adsorbs them through zeolite molecular sieve wheels. The gas adsorbed through the zeolite wheels can be directly discharged.
當吸附大量揮發(fā)性有機物的沸石轉(zhuǎn)輪進入高溫脫附區(qū)時，小風量的熱空氣將沸石轉(zhuǎn)輪上的揮發(fā)性有機物分子脫附，轉(zhuǎn)化為高濃度廢氣，并將脫附風機送入后端的催化燃燒系統(tǒng)進行催化燃燒處理。分解產(chǎn)生的熱量部分通過內(nèi)部熱交換再次進入催化燃燒系統(tǒng)，以減少能量損失，部分分解后的氣體直接排放到空氣中。
When the zeolite wheel that adsorbs a large amount of volatile organic compounds enters the high-temperature desorption zone, the small amount of hot air will desorb the volatile organic compound molecules on the zeolite wheel, convert them into high concentration waste gas, and send the desorbed fan to the catalytic combustion system at the rear end for catalytic combustion treatment. The heat generated by decomposition enters the catalytic combustion system again through internal heat exchange to reduce energy loss, and some of the decomposed gases are directly discharged into the air.

在此過程中，電氣控制系統(tǒng)嚴格控制催化燃燒產(chǎn)生的熱量。當超過設(shè)定值時，通過調(diào)整脫附管道的自動閥門來補充冷空氣，降低廢氣濃度，減少熱量產(chǎn)生；兩個分子系統(tǒng)相互結(jié)合，反復(fù)循環(huán)。無VOCS時，設(shè)備可停止運行。同時，為了設(shè)備的處理和安全，在停止催化氧化系統(tǒng)后，應(yīng)冷卻這些設(shè)備，以保護設(shè)備的正常使用。
During this process, the electrical control system strictly controls the heat generated by catalytic combustion. When the set value is exceeded, adjust the automatic valve of the desorption pipeline to supplement cold air, reduce the concentration of exhaust gas, and reduce heat generation; Two molecular systems combine with each other and cycle repeatedly. When there is no VOCS, the device can stop running. At the same time, for the treatment and safety of equipment, after stopping the catalytic oxidation system, these equipment should be cooled to protect their normal use.
二、沸石分子篩轉(zhuǎn)輪吸附濃縮。
2、 Zeolite molecular sieve wheel adsorption concentration.
沸石是一種晶體礦石，我們使用的沸石分子篩是沸石的化合物。
Zeolite is a crystalline ore, and the zeolite molecular sieve we use is a compound of zeolite.
沸石分子篩輪分為吸附區(qū)、脫附區(qū)和冷卻區(qū)三部分，每部分由耐熱、耐溶劑密封材料分開。沸石輪可在各功能區(qū)連續(xù)運行，同時吸附脫附冷卻。
The zeolite molecular sieve wheel is divided into three parts: adsorption zone, desorption zone, and cooling zone, with each part separated by heat-resistant and solvent resistant sealing materials. The zeolite wheel can operate continuously in various functional areas while adsorbing, desorbing, and cooling.
通過前端過濾器進行初步過濾后，VOCS被沸石分子篩吸附到沸石分子篩轉(zhuǎn)輪的吸附區(qū)。有機廢氣凈化后，直接從沸石分子篩轉(zhuǎn)輪排出，通過煙囪進入空氣。
After preliminary filtration through the front-end filter, VOCS is adsorbed by the zeolite molecular sieve to the adsorption area of the zeolite molecular sieve wheel. After purifying the organic waste gas, it is directly discharged from the zeolite molecular sieve wheel and enters the air through the chimney.
旋轉(zhuǎn)輪上吸附的VOCS在脫附區(qū)被脫附，風量約200℃。濃縮，濃縮倍數(shù)一般為5~25倍。濃縮倍數(shù)n=吸附面積*吸附速度/脫附面積/脫附速度。
The VOCS adsorbed on the rotating wheel is desorbed in the desorption zone, with an air volume of about 200 ℃. Concentration, the concentration ratio is generally 5-25 times. Concentration factor n=adsorption area * adsorption rate/desorption area/desorption rate.
脫附后的沸石輪在冷卻區(qū)冷卻。冷卻區(qū)空氣加熱后作為再生空氣，達到節(jié)能效果。上述過程反復(fù)循環(huán)，以達到廢氣凈化的目的。
The detached zeolite wheel is cooled in the cooling zone. The air in the cooling zone is heated and used as regenerative air to achieve energy-saving effects. The above process is repeated to achieve the purpose of exhaust gas purification.
催化燃燒。
Catalytic combustion.
沸石轉(zhuǎn)輪通過脫附區(qū)后，VOCS進入脫附管道，通過脫附風機進入換熱器換熱。VOCS將催化燃燒產(chǎn)生的部分熱量帶入催化燃燒器，加熱和加熱催化劑催化處理。催化燃燒技術(shù)可在低溫（300℃~500℃）下實現(xiàn)VOCS95%以上的凈化效率，完全反應(yīng)后產(chǎn)生CO2和H2O，同時釋放大量熱量。
After the zeolite runner passes through the desorption zone, VOCS enters the desorption pipeline and enters the heat exchanger for heat exchange through the desorption fan. VOCS brings some of the heat generated by catalytic combustion into the catalytic burner, heating and heating the catalyst for catalytic treatment. Catalytic combustion technology can achieve a purification efficiency of over 95% of VOCS at low temperatures (300 ℃~500 ℃), producing CO2 and H2O after complete reaction, while releasing a large amount of heat.
鄭州客戶廠區(qū)安裝了RCO催化燃燒設(shè)備。
The customer factory in Zhengzhou has installed RCO catalytic combustion equipment.
部分熱量通過混合罐進入旋轉(zhuǎn)輪脫附區(qū)，將吸附在旋轉(zhuǎn)輪上的揮發(fā)性有機物脫附；部分進入換熱器換熱，部分熱量通過煙囪排出，部分通過換熱器的揮發(fā)性有機物再次進入催化燃燒器。反復(fù)回收可以最大限度地減少能量損失，實現(xiàn)廢氣自催化分解的效果。
Part of the heat enters the rotary wheel desorption zone through the mixing tank to desorb the volatile organic compounds adsorbed on the rotary wheel; Part of the heat enters the heat exchanger for heat exchange, part of the heat is discharged through the chimney, and part of the volatile organic compounds that pass through the heat exchanger enter the catalytic burner again. Repeated recycling can minimize energy loss and achieve the effect of exhaust gas self catalytic decomposition.
