A denitrification tower with a compression device

Abstract

The invention discloses a denitration tower with a compression unit. The tower comprises a tower body, a smoke inlet tube, an upper-lower pushing and compressing device, an activated carbon adsorption bed and a smoke outlet pipe, wherein the smoke inlet tube, the upper-lower pushing and compressing device, the activated carbon adsorption bed and the smoke outlet pipe are connected to the tower body from top to bottom, the inner wall of the tower body is provided with several denitration and adsorption structures as a whole, the upper-lower pushing and compressing device and the activated carbon adsorption bed are both fixedly provided with soot blowers, and the upper-lower pushing and compressing device is connected with the tower body in a matched mode through at least three vertical slide rails fixed to the inside of the tower body; the upper-lower pushing and compressing device comprises a pushing plate and a pushing power source, and the central portion of the pushing plate is provided with a smoke discharging hole of which the diameter is smaller than one third that of the pushing plate; the joint of the smoke inlet tube and the tower body is further provided with an electromagnetic locking valve, and the electromagnetic locking valve is connected with the pushing power source. In the denitration tower with the compression unit, smoke flow is accelerated, smoke close to a smoke discharging opening of the pushing plate is accelerated to flow to the activated carbon adsorption bed, and thus the efficiency of the activated carbon adsorption bed in adsorbing the smoke is improved.

Description

technical field [0001] The invention relates to the technical field of denitration towers, in particular to a denitration tower with a compression device. Background technique [0002] In the denitrification industry, the structure of the currently used two-fluid spray gun for denitrification is: including an ammonia solution storage tank, a compressed air storage device, a gas-liquid mixing device, and a gun barrel connected to the gas-liquid mixing device. A nozzle is set inside the gun barrel at the nozzle; a solution inlet and a compressed air inlet are opened on the gas-liquid mixing device, and a protective gas inlet is opened on the gun barrel, and the ammonia solution storage tank passes through the ammonia water inlet pipe and the gas-liquid mixing device. The solution inlet is connected, and a liquid inlet regulating valve is arranged on the ammonia water inlet pipe; the compressed air gas storage device is connected with the compressed air inlet of the gas-liquid ...

AI Technical Summary

Problems solved by technology

The shortcoming of this two-fluid spray gun for denitrification is that the service life of the gun barrel is short under high temperature conditions, and when the ammonia solution is sprayed into the coal-fired boiler from the nozzle of the gun barrel, the residual ammonia solution at the nozzle of the gun barrel is very prone to hang. The whisker phenomenon, the ammonia solution that has the whisker phenomenon is easy to flow along the outer wall of the gun tube located in the coal-fired boiler to the inner lining of the water-cooled wall of the high-temperature coal-fired boiler, thereby causing corrosion to the inner lining of the water-cooled wall. hidden dangers in production safety
