Organic waste gas treatment equipment

Abstract

The invention provides an organic waste gas treatment equipment which comprises an inner cylinder and a tower body, wherein the lower part of the outer wall of the tower body is provided with a gas inlet; the top of the outer wall of the tower body is provided with an absorbent inlet and a clean gas outlet; the top of the inner wall of the tower body is welded with an external trumpet-shaped distributor; the inner cylinder is fixed on the wall of the tower body by stand bars and is kept concentric with the tower body; the upper part of the outer wall of the inner cylinder is provided with an internal trumpet-shaped distributor; two conduits are arranged between the internal distributor and the external distributor and used for connecting the internal distributor with the external distributor; the lower end of the internal distributor is circumferentially welded with supporting points on the outer wall of the inner cylinder by every 60 degrees; and the edge of each supporting point is 1.5 mm away from the outer wall of the inner cylinder. The invention has the outstanding advantage of resource saving, and can be popularized in the resource recycling treatment processes for waste gas and the like.

Description

technical field [0001] The invention relates to the field of chemical and chemical organic waste gas treatment, in particular to an organic waste gas treatment equipment. Background technique [0002] For a long time, people have been committed to the research of organic waste gas treatment technology. The pollutants contained in the dry waste gas in the chemical industry are mainly organic waste gas steam. As early as 1925, Europe developed a fixed-bed activated carbon adsorption device, and Japan also began in 1958. Use this technique. Activated carbon adsorption is a very classic and mature method, which can be used to treat various concentrations of organic waste gas at room temperature. However, when dealing with low-concentration and large-volume organic waste gas, the equipment is huge and uneconomical. So far, people have researched and developed a series of effective control technologies. Among these technologies, thermal destruction method, adsorption method, con...

AI Technical Summary

Problems solved by technology

The disadvantage of the adsorption method is that the moisture in the gas to be treated has a great influence on the adsorption capacity of the activated carbon layer.

When the relative humidity of the gas exceeds 50%, the adsorption capacity of activated carbon for organic matter will be greatly reduced, and the processing equipment is huge and the process is complicated. When there are colloidal substances or other impurities in the exhaust gas, the adsorbent is prone to failure.
