Thermal power station exhaust gas filtering apparatus

Abstract

The invention discloses a thermal power station exhaust gas filtering apparatus, which comprises a box. The bottom of the left side of the box is communicated with an air inlet pipe. The bottom of theair inlet pipe is communicated with a short pipe. The bottom of the short pipe is communicated with a collection box. A fan and a first filtering plate are arranged in sequence from right to left inthe inner cavity of the air inlet pipe. The top and bottom of the fan are both fixedly connected to the inner wall of the air inlet pipe through supports. The bottom of the first filtering plate contacts with the bottom of the inner cavity of the air inlet pipe. The provided exhaust gas filtering apparatus can deliver disinfectant to the inner cavity of a cross pipe and spray the disinfectant through a nozzle; the disinfectant contacts with exhaust gas and carries out reactions with exhaust gas to disinfect exhaust gas; through an active carbon layer, a photocatalyst plate, and a UV lamp, harmful and toxic gas in the air can be degraded effectively, multiple bacteria can be killed effectively, the toxin released from bacteria or fungi can be decomposed or harmlessly processed, and the exhaust gas purifying performance is enhanced.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a waste gas filter device for thermal power stations. Background technique [0002] Exhaust gas purification mainly refers to the treatment of industrial waste gas such as dust particles, flue gas, odorous gas, and toxic and harmful gases generated in industrial places. Common exhaust gas purification includes factory smoke and dust exhaust gas purification, workshop dust exhaust gas purification, organic waste gas purification, Exhaust gas odor purification, acid-base exhaust gas purification, chemical waste gas purification, etc. The gas discharged from thermal power plants contains a large amount of suspended solids and toxic and harmful substances, which can easily cause blockage of the filter plate in the filter device and affect the filtration of exhaust gas. At the same time, the filter device The poisonous and harmful substances in the gas cannot be effectivel...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a waste gas filter device for thermal power plants, which has the advantages of avoiding filter plate clogging and good filtering effect, and solves the problem that the gas discharged from thermal power plants contains a large amount of solid suspended matter and toxic and harmful substances, which is very easy to cause filtration. The blockage of the filter plate in the device affects the filtration of exhaust gas. At the same time, the filter device cannot effectively remove toxic and harmful substances in the gas, and the filtering effect is poor, which is not convenient for people to use.
