Activated carbon adsorption, desorption and catalytic combustion all-in-one machine and working method thereof

Abstract

The invention discloses an activated carbon adsorption, desorption and catalytic combustion all-in-one machine and a working method thereof. The machine comprises a dry type filter box, an activated carbon adsorption purification device, a catalytic combustion chamber, an electric control box, an exhaust chimney, a desorption fan and an adsorption fan; an adsorption air inlet, an adsorption air outlet, a desorption air inlet and a desorption air outlet are formed in the activated carbon adsorption purification device; the adsorption air inlet is connected with the dry type filter box through an adsorption air inlet pipe; the adsorption air outlet is connected with an air inlet of the adsorption fan through an adsorption air outlet pipe, an air outlet of the adsorption fan is connected withan exhaust chimney, the desorption air inlet is connected with a catalytic combustion chamber through a desorption air inlet pipe, the desorption air outlet is connected with an air inlet of the desorption fan through a desorption air outlet pipe, and an air outlet of the desorption fan is connected with the catalytic combustion chamber. An activated carbon box and the catalytic combustion chamber are connected through a double-gas-path structure, activated carbon in the activated carbon box can be directly desorbed and regenerated by the catalytic combustion chamber after adsorption saturation, resources are saved, and the air purification cost is reduced.

Description

technical field [0001] The invention relates to an air purification device, in particular to an activated carbon adsorption-desorption catalytic combustion integrated machine and its working method. Background technique [0002] At present, although the conventional activated carbon purification equipment can purify the exhaust gas very well, after the activated carbon is adsorbed and saturated, it is either discarded directly, or a special activated carbon desorption equipment is used for desorption and regeneration to continue to use. If it is discarded directly, the activated carbon is wasted; If special desorption equipment is used, it is usually necessary to set up the activated carbon adsorber, activated carbon desorption device and catalytic combustion device separately. There are many equipments and complicated process flow; both of them will cause waste of resources and increase the cost of air purification. Contents of the invention [0003] In order to solve the...

[0002] At present, although the conventional activated carbon purification equipment can purify the exhaust gas very well, after the activated carbon is adsorbed and saturated, it must either be discarded directly, or use a special activated carbon desorption equipment for desorption regeneration and continue to use. If it is discarded directly, the activated carbon is wasted; If special desorption equipment is used, it is usually necessary to set up the activated carbon adsorber, activated carbon desorption device and catalytic combustion device separately. There are many equipments and complicated process flow; both of them will cause waste of resources and increase the cost of air purification.
