Industrial waste gas treatment device for separating internally-hung biological carriers

Abstract

The invention discloses an industrial waste gas treatment device for separating internally-hung biological carriers. The invention belongs to the technical field of waste gas treatment. According to industrial waste gas treatment device for separating the internally-hung biological carriers, waste gas is sprayed and washed with water in the waste gas water-washing box; on one hand, some large particles in the waste gas can be effectively washed and filtered; on the other hand, reduction of the waste gas temperature is further facilitated, the influence of high-temperature waste gas on the biological activity of biological filler layers and microbial film layers in a waste gas biological treatment cylinder is effectively avoided; a plurality of groups of biological filler layers and microbial film layers are arranged up and down and are arranged in the multiple treatment cavities respectively, the introduced waste gas passes through the multiple treatment cavities in a balanced manner and is subjected to independent treatment, the gas resistance is low, the gas blockage is not easily caused, the gas treatment effect is effectively improved, and the biological filler layers and the microbial film layers are easily subjected to oxygen supply through the matched arrangement of aeration pipes.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, and more specifically relates to an industrial waste gas treatment device for separating and hanging biological carriers. Background technique [0002] Exhaust gas purification mainly refers to the work of treating industrial waste gas such as dust particles, flue gas smoke, odorous gas, and toxic and harmful gases generated in industrial places. There are many types of pollutants in exhaust gas, their physical and chemical properties are very complex, and their toxicity is also different. Generally, exhaust gas contains sulfur dioxide, nitrogen oxides (NOx), hydrocarbons, etc. [0003] If the exhaust gas from industrial fuel combustion is discharged directly, it will have an impact on the atmospheric environment, and the exhaust gas with high temperature will increase the atmospheric temperature in the emission area to a certain extent after being discharged into the atmosphere.

Problems solved by technology

However, the biological method in the prior art is such as: biotrickling filter tower and biofilter microbial system, the gas is introduced into the packing layer of the biotrickling filter tower and the biofilter, the exhaust gas is not easy to diffuse evenly in the packing layer, when the gas is concentrated into When reaching one part of the packing layer, the effective conduction area of ​​the gas is small, and the gas resistance is high. It is difficult for the gas to be in uniform and full contact with the packing layer, which affects the treatment effect. biological activity of microorganisms
