Convenient-to-replace filtering device for desulfurization tower

Abstract

The invention discloses a convenient-to-replace filtering device for a desulfurization tower. The convenient-to-replace filtering device for the desulfurization tower comprises a main desulfurizationtower body, a mounting frame, a gas inlet, a filtering device body, a filtering net and a desulfurization spraying pipe, wherein a mounting opening is formed in the front side of the main desulfurization tower body; a sealing plate is attached to the mounting opening; the inner side of the sealing plate is in sealed connection with the mounting opening through a sealing gasket; meanwhile, adjusting plates are welded to the two sides of the sealing plate; connecting sleeves are welded to the outer ends of the adjusting plates, and are in bolted connection with the telescopic ends of telescopicdevices through fixed openings; dispersing holes are formed in a dispersing plate; an exhaust hood is arranged below the dispersing plate; the exhaust hood communicates with the gas inlet in the lowerend of the main desulfurization tower body; and a desulfurization cavity is formed in the main desulfurization tower body. According to the convenient-to-replace filtering device for the desulfurization tower, under the condition that the main desulfurization tower body is not disassembled, the filtering device in the main desulfurizing tower body can be replaced and maintained, so the labor intensity of maintenance workers is greatly reduced, and the maintenance time of the maintenance workers is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of desulfurization towers, in particular to a conveniently replaceable desulfurization tower filter device. Background technique [0002] The flue gas desulfurization tower is a kind of tower equipment for desulfurization treatment of industrial waste gas. Its main principle is to spray the alkaline desulfurization liquid through the spray pipe, so that the sprayed alkaline desulfurization liquid enters the desulfurization chamber inside the desulfurization tower. The function of washing the industrial waste gas in the environment, and then desulfurizing the industrial waste gas, so that the industrial waste gas can reach the emission standard, for example, a kind of flue gas desulfurization based on Karman vortex street with the application number of 201910256283.9 and the application date of 2019.04.01 The tower includes a shell with an internal cavity and a cylindrical Karman vortex generator arranged in ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a desulfurization tower filter device that is easy to replace, to solve the existing desulfurization tower filter device on the market proposed by the above-mentioned background technology, in the process of use, the desulfurization tower filter device needs to be replaced regularly And cleaning, in the process of replacement or cleaning, because the desulfurization tower filter device is inside the desulfurization tower, the disassembly process is complicated, it is inconvenient for maintenance personnel to install and disassemble, and the desulfurization effect is poor
