Adsorption and filtration treatment device for organic waste gas

Abstract

The invention discloses an adsorption filtering treatment device for organic waste gas. The device comprises an adsorption filtering device, wherein a filter assembly of the adsorption filtering device consists of filtration bins and filters in the filtration bins, which are combined; filtering membranes are arranged on the outer surfaces of the filters; adsorption materials are attached to the outer surfaces of the filtering membranes; a feeding device, discharging devices and a gas inlet device are connected to spaces of the filtering bins outside the filtering membranes through valves respectively; a purified gas collection pipe is connected to inner cavities of the filters; a suction pipe of the feeding device is connected with a charging bucket; the discharging devices are connected with an ash discharge port; the purified gas collection pipe is connected with a purified gas emission pipe. The adsorption filtering treatment device for the organic waste gas is reasonable in structure and large in adsorption filtering area, and has good purification treatment effects; saturated adsorption materials are discharged from a machine body for incineration, so that secondary pollution is avoided.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to an adsorption and filtration treatment device for organic waste gas. technical background [0002] Organic waste gas is generally flammable and explosive, toxic and harmful, insoluble in water, soluble in organic solvents, and difficult to treat. In the treatment of organic waste gas, various principles such as organic waste gas activated carbon adsorption treatment method, catalytic combustion method, catalytic oxidation method, acid-base neutralization method, and plasma method are commonly used. At present, the most widely used treatment system for organic waste gas in my country is the activated carbon fixed bed adsorption + catalytic combustion treatment system. The system is to pack activated carbon in a fixed bed, and then combine the adsorption bed with a catalytic combustion device to form a purification treatment system. [0003] However, there...

[0003] However, there is a defect in this system, that is, the regeneration and desorption temperature of the activated carbon used as the adsorption material is generally controlled below 140°C. Such a temperature is difficult to desorb organic waste gas with a boiling point above 140°C.

However, when the activated carbon absorbs such gases, the desorbed carbon layer is prone to smoldering when it is desorbed above 140°C; secondly, the desorption of activated carbon is actually to re-release the VOCs that were originally adsorbed in the micropores of the activated carbon, and the eradication has not been achieved. the goal of
