Description

Background

At present, the treatment methods of organic waste gas are various, and a condensation method, an absorption method, a combustion method, a catalytic combustion method, an adsorption method, a biological method and the like are commonly used.

The method for adsorbing the zeolite comprises the following steps: the zeolite is attached to the framework material to be made into a disc or a cylinder, the disc or the cylinder alternately passes through the adsorption area and the desorption area through rotation of the disc or the cylinder, the low-concentration organic waste gas is adsorbed in the adsorption area to achieve the purpose of concentration, desorption is carried out after the organic waste gas enters the desorption area, and the desorbed organic waste gas enters the catalytic oxidation bed to be subjected to flameless combustion purification treatment.

The method concentrates the low-concentration organic waste gas into high-concentration organic waste gas through zeolite and then thoroughly purifies the high-concentration organic waste gas through catalytic combustion. The method is suitable for the working process of continuous production with large air quantity and low-concentration organic waste gas and stable waste gas concentration.

Therefore, the desorbed high-concentration organic gas is directly delivered into the air, and the pollution to the environment is further prevented. Here, it should be noted that since the inner support frame 210 and the outer support frame 310 are not a large force-bearing member, the inner support frame 210 and the outer support frame 310 are not disassembled, so the inner support frame 210 may be welded on the second bracket 700 and the outer support frame 310 may be welded on the first bracket 600.
