Filtering device for waste gas purification

Abstract

The invention discloses a filtering device for waste gas purification. The filtering device comprises a filtering tank, a gas storage tank and a dust hopper. The filtering device is characterized in that a gas inlet is formed in the left side of the filtering tank, a gas outlet is formed in the right side of the filtering tank, the bottom of the filtering tank is connected with the dust hopper, a plurality of filter bag layers are sequentially arranged inside the filtering tank from left to right, the space among the filter bag layers is divided into a plurality of separating cavities, a gas ejector pipe is arranged at the top of each separating cavity, the top of each gas ejector pipe is communicated with a conveying pipe, the other end of the conveying pipe is communicated with the gas storage tank, the bottom of the dust hopper is connected with a vibrating conveyer through a pipeline, and level switch is arranged on the pipeline and interlocked with the vibrating conveyer. The filtering device is simple in structure and good in pulse dust removal effect, waste gas follow-up treatment effects can be improved, and waste gas treatment efficiency is enhanced.

Description

technical field [0001] The invention relates to the technical field of waste gas purification equipment, in particular to a filter device for waste gas purification treatment. Background technique [0002] The exhaust gas processor with microwave and ultraviolet irradiation is mainly used for the harmless treatment of various low-to-medium concentration volatile organic compounds (VOC5), malodorous gas, oil fume and so on. There are many kinds of organic waste gases, up to tens of thousands, which are seriously harmful to human health. They not only stimulate human eyes, nose, respiratory tract, etc., but also damage organs. The symptoms after poisoning are mostly respiratory system, Digestive system, circulatory system and nervous system and other diseases, and mostly cumulative. The existing organic waste gas treatment is usually decomposed by microwave ultraviolet light. However, the waste gas usually contains a lot of dust, which cannot be treated by microwave and ultra...

Problems solved by technology

At present, the commonly used ash hopper is open, and because the pulse dust collector discharges ash at intervals, when the dust is not unloaded, the airflow will pass through the open ash hopper and blow into the pulse dust collector from bottom to top, which will affect the pulse dust collector. dust removal effect
