The organic waste gas produced by the spray painting process has the characteristics of large air volume and low concentration, and also contains a small amount of paint mist. Five sets of organic waste gas purification system design, each main purification system include exhaust fan, pre processor, adsorption bed, catalytic combustion bed, desorption fan, cooling fan and control cabinet, regeneration of activated carbon adsorption bed can be arranged according to the use of operation.
Spray paint waste gas contains a small amount of paint mist and dust, such as not to deal with it will stick to plug the honeycomb activated carbon micropore, so that activated carbon failure. The exhaust gas from the workshop enters into the fiber filter first, and then a small amount of paint mist and dust are removed by the way of blocking.
Remove exhaust paint mist, dust, through reasonable air distribution, making it evenly through the flow section of the activated carbon layer of activated carbon adsorption in the bed, in a certain residence time, due to the mutual gravitational activated carbon surface and organic waste gas interaction physical adsorption (also known as Fan Dehua adsorption), the is the adsorbate (organic) and adsorbents (activated carbon) do not react to the interaction process faster, the nature of the material itself does not change the adsorption in the adsorption process, the adsorption process is reversible; thus organic components in waste gas adsorbed into the pores of activated charcoal, to purify the waste gas, gas after purification by fan and pipeline discharge.
(3) desorption catalytic combustion
The reaction equation is as follows:
Noble metal catalyst
The adsorption bed saturated adsorption should stop, through the valve switch into desorption, desorption process is as follows: start the fan, open the corresponding valve and electric heater to preheat the catalyst bed inside the catalytic combustion, hot air and produce a certain amount, when the bed temperature reaches the set value of the hot air into the the adsorption bed of activated carbon by pyrolysis from high concentration of organic gases, the desorption fan introduction of catalytic combustion in bed, under the effect of noble metal catalyst at a lower temperature for catalytic combustion of organic components into non-toxic, harmless CO2 and H2O, and release a lot of heat, can maintain the catalytic combustion required for the ignition temperature of the exhaust gas combustion process without adding the basic energy (electricity), and the part of the heat back for the desorption and regeneration of activated carbon adsorption bed, thereby Greatly reduces energy consumption. If the two stage heat exchanger can partly recover the heat in the tail gas, it can produce some economic benefits while realizing the environmental benefits.
When the combustion exhaust gas concentration is higher, the reaction temperature is increased, the cold air blower is automatically opened, and the fresh cold air is added to remove the low temperature and increase the oxygen content of the gas, so as to ensure the safe and efficient operation of the catalytic combustion bed.
