A pressure-changing capacity expansion self-cleaning exhaust gas high-efficiency filter device

Abstract

The invention discloses a pressure-transforming capacity expansion self-cleaning high-efficiency filter device for exhaust gas, which belongs to the technical field of exhaust gas treatment. The invention utilizes the atmospheric pressure formed on the outside of the filter screen when it is blocked to make a pair of filter screens rotate and approach each other, so that the fixed plate is compressed by the spring. Gradually move up under the action of the elastic force, drive the inclined cleaning plate to move up against the surface of the filter screen, scrape off the particles attached to the surface of the filter screen, as the fixed rod and the fixed plate gradually approach, when the push plate passes through the pressure relief hole When the blocking plate is pushed to rotate, the pressure release hole is opened, and the exhaust gas enters between a pair of inclined cleaning plates and is then filtered by the filter screen, so that the air pressure outside the filter screen gradually decreases. Far away from returning to the original position, the process of filtering and purifying the exhaust gas is continued. The present invention automatically realizes the cleaning process of the filter screen without interrupting the filtering process through the change of air pressure caused by the blockage, thereby realizing a continuous and efficient process of exhaust gas purification.

Description

technical field [0001] The present invention relates to the technical field of waste gas treatment, and more particularly, to a pressure-variable capacity expansion self-cleaning type high-efficiency waste gas filter device. Background technique [0002] Industrial waste gas refers to the general term for various pollutant-containing gases discharged into the air generated during the fuel combustion and production process in the factory area of ​​the enterprise. These exhaust gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (fog), lead and mercury, beryllium compounds, soot and productive dust, which are discharged into the atmosphere and pollute the air. These substances enter the human body through the respiratory tract through different routes, some directly cause harm, and some have an accumulation effect, which will seriously endanger human health. Industrial waste ...

AI Technical Summary

Problems solved by technology

[0003] For the treatment of particulate pollutants such as smoke and dust contained in exhaust gas, filtration is generally used for purification, but in filtration treatment, the most common problem is the blockage of filter equipment caused by particulate matter, which not only interrupts the purification process, but also seriously reduces the purification process. Efficiency, and also makes exhaust gas filtration less effective
