Unitized self-replacement type efficient waste gas filtering device

Abstract

The invention discloses a unitized self-replacement type efficient waste gas filtering device. The invention belongs to the technical field of waste gas filtration; by unitizing an existing filteringlayer and setting a plurality of replaceable supplementing units on the upper side of the unit filtering layer, when the fiber filtering layer in the filtering state is blocked, the fiber filtering layer can be deformed upwards under the action of air pressure increase; the contact matching of the bipolar clamping ball and the heat generation mechanism is utilized, the conduction mode of heat conduction is changed from weak flowing air conduction to efficient conduction of a contact type heat conduction material; then, based on the heat conduction effect, the heat is quickly conducted to the bipolar clamping ball for fixing the fiber filtering layer; the state of the bipolar clamping ball is changed through the heating effect, the bipolar clamping ball is enabled to deform into a semispherical state and then automatically falls off under the action of gravity and is replaced by the supplementing unit on the upper side, so that self-replacement of the fiber filtering layer is achieved,uninterrupted efficient filtering of waste gas can be achieved, and the filtering effect and efficiency are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of exhaust gas filtration, and more specifically relates to a unitized self-replacement exhaust gas high-efficiency filter device. Background technique [0002] The waste gas emitted by various industrial furnaces in metallurgy, machinery, chemical industry, electric power and other industries contains a large amount of dust and harmful gases, which is one of the main factors causing environmental pollution. [0003] According to different pollutants, industrial waste gas can be divided into dust removal, desulfurization and denitrification technology, organic waste gas VOC removal, etc. Industrial waste gas containing dust is mainly caused by the burning of fossil fuels (coal and oil) during production and living activities, rock drilling and blasting during mining, crushing and screening of building materials, smelting and casting, etc. Air pollutants mainly include dust particles, carbon dioxide, sulfur ...

AI Technical Summary

Problems solved by technology

[0005] Then, the common problem faced by existing filtering devices is the clogging problem. Since industrial waste gas often contains a large amount of dust and particle pollutants, clogging will inevitably occur after a period of filtration, which will affect the filtration efficiency and effect. At this time The need to shut down for maintenance and cleaning will undoubtedly greatly reduce the continuity and high-speed performance of exhaust gas filtration. At the same time, cleaning is very troublesome and requires a lot of manpower, material resources and financial resources.
