Vertical type gas filtering and purifying device

Abstract

The invention discloses a vertical type gas filtering and purifying device which comprises a barrel body, wherein a spiral shaft is mounted in an inner cavity of the barrel body along the axial line of the barrel body; the vertical type filter gas purifying device further comprises a gas inlet formed on the upper part of the side wall of the barrel body, an exhaust opening formed on the lower part of the side wall of the barrel body, a material inlet formed on the top of the barrel body, a waste outlet formed on a position, which corresponds to the lower end of the spiral shaft, on the side wall of the barrel body and a filter net fixedly arranged along a direction perpendicular to the axial line of the barrel body; the filter net is located below the spiral shaft; a cavity in the upper part of the filter net is filled with granular biomasses; the granular biomasses are carried by the filter net and cannot leak; the exhaust opening is arranged below the filter net. According to the vertical type filter gas purifying device, no harmful gas is discharged into air, no sewage treatment process is needed, and the problem of sewage discharging outer is successfully solved. Therefore, the environment is protected, a lot of engineering construction investment is saved, and the vertical type filter gas purifying device has the advantages of simplicity and convenience in operation and low cost.

Description

technical field [0001] The invention belongs to the field of pyrolysis and gasification, and in particular relates to a vertical filter gas purification device. Background technique [0002] In the existing pyrolysis gasification furnace device, during the combustion and gasification process of garbage in the furnace, the combustible gas produced contains various polluting particles, such as tar, dioxin, dust, water mist, etc. Since various pollutants are mixed in the combustible gas, the combustible gas is impure and cannot be used as power generation energy. Moreover, because it pollutes the air, soil, water, etc., endangering the health of the people, it is not allowed to discharge into the air. [0003] The traditional filter and purification device for combustible gas with impurities uses chimney or tower spraying to add activated carbon and other chemicals to neutralize polluting particles and obtain relatively pure combustible gas. However, water or other chemical s...

AI Technical Summary

Problems solved by technology

However, water or other chemical substances are needed in this treatment process. After the treatment, the aqueous solution will also be polluted, and the sewage treatment process must be introduced, resulting in high project cost, cumbersome treatment process, and can not cure air, soil, water and other pollution.
