Denitrating tower provided with bladder type compression device

Abstract

The invention discloses a denitrating tower provided with a bladder type compression device. The denitrating tower comprises a tower body, a smoke feeding pipeline, an upper and lower pushing compression device, an active carbon absorption bed and a smoke discharging pipe, wherein the smoke feeding pipeline, the upper and lower pushing compression device, the active carbon absorption bed and the smoke discharging pipe are connected onto the tower body from top to bottom; a plurality of denitrating adsorption structures are arranged on the inner wall of the tower body and positioned between the upper and lower pushing compression device and the bottom of the tower body; an ash blowing device is fixed on each of the upper and lower pushing compression device and the active carbon absorption bed; in addition, the upper and lower pushing compression device is matched and connected with the tower body through at least three vertical slide rails fixed on the inside of the tower body; the upper and lower pushing compression device comprises a pushing plate, a pushing power source and a bladder type compression device; a smoke discharging hole with the diameter being smaller than 1 / 3 of the diameter of the pushing plate is formed in the center position of the pushing plate; a return spring is also arranged inside the bladder compression device. The denitrating tower has the advantages that the smoke gas flowing is accelerated; the smoke gas near the smoke discharging opening of the pushing plate flows to the active carbon adsorption bed in an accelerated way; the smoke gas adsorption efficiency of the active carbon adsorption bed is improved.

Description

technical field [0001] The invention relates to the technical field of denitrification towers, in particular to a denitrification tower equipped with a bladder type 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 compresse...

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
