Problems solved by technology

However, the catalytic combustion method is not suitable for the treatment of large air volume and low concentration organic waste gas, because a large amount of fuel needs to be added to support combustion, which increases the treatment cost and easily causes secondary pollution.

Embodiment

[0021] Embodiment: Take the organic waste gas that the water curtain spray booth produces as an example to illustrate the working process of the present invention:

[0022] In the present invention, two activated carbon adsorption beds A and B work alternately. When one is performing adsorption operation, the other is performing desorption operation. The operation time of adsorption and desorption depends on the concentration of organic substances contained in the waste gas.

[0023] The working process of the adsorption operation is that the valves at the inlet and outlet of the adsorption gas of the activated carbon adsorption bed A or B are opened, and the desorption inlet and outlet valves are closed; The organic waste gas is sucked into the dust filter device 3, and the dust and paint mist in the waste gas are filtered out to prevent them from blocking the gaps of the adsorbent in the activated carbon adsorption bed and affecting the adsorption effect; then, the waste gas ...

Abstract

The invention discloses an organic waste gas multifunctional integral processing device, which comprises a programmable logic controller (PLC) control system, a dust filter device, active carbon adsorption beds A and B which are connected in parallel and a catalytic combustion bed. When organic waste gas is adsorbed, the organic waste gas firstly enters into the dust filter device to remove suspended solid; then enters into the active adsorption beds to remove organic substances; finally the purified waste gas is pumped through an adsorption exhaust fan and discharged on standard through an adsorption high-altitude discharge branch. When active carbon is desorbed and regenerated, the hot gas generated by the catalytic combustion bed is pressurized through a desorption fan, and then enters into the active absorption beds to reversely desorb and regenerate the saturated active carbon; the desorbed waste gas enters into the catalytic combustion bed; organics are burned to generate water and carbon dioxide; the hot gas generated at the same time is used for desorbing the active carbon. The processing device is controlled by the PLC, thereby realizing automatic switch between the two absorption beds, so that adsorption and desorption are carried out at the same time. The invention combines two technologies of adsorption and catalytic combustion organically and has complementary advantages.

Description

technical field [0001] The invention relates to a multifunctional treatment device for organic waste gas, in particular to a multifunctional integrated treatment device for organic waste gas activated carbon adsorption, hot gas desorption and catalytic combustion. Background technique [0002] At the present stage of engineering practice, the process methods for treating organic waste gas are mainly adsorption method and catalytic combustion method. [0003] The adsorption method is to use activated carbon and other substances with adsorption capacity to absorb organic waste gas to achieve the purpose of eliminating harmful pollution. The operating temperature is normal temperature, which is suitable for the purification of large air volume and low concentration organic waste gas. But after the adsorbent is saturated, it will be treated as industrial solid waste, which will not only increase the operating cost, but also affect the production because of the need to replace t...
