Coke oven gas desulfurization tower

Abstract

The invention provides a coke oven gas desulfurization tower which comprises a tower body, a slurry discharge port is fixedly mounted at the lower end of the outer surface of one side of the tower body, a gas inlet is fixedly mounted in the middle of the outer surface of the other side of the tower body, and a demisting plate is fixedly mounted at the upper end in the tower body. A clean water spraying mechanism is fixedly installed at the upper end of the interior of the tower body and located below the demisting plate, a slurry spraying mechanism is fixedly installed in the middle of the interior of the tower body, a collecting channel is fixedly installed at the position, located below the slurry spraying mechanism, of the inner surface of the tower body, and flow guide pipes are fixedly installed on the periphery of the outer surface of the lower end of the collecting channel; according to the coke oven gas desulfurization tower, solid particles attached to the inner surface of the tower body of the coke oven gas desulfurization tower can be cleaned, the interior of the tower body is prevented from being corroded, the desulfurization tower is prevented from being damaged, meanwhile, the solid particles in discharged slurry are filtered, the filtered solid particles are collected, a slurry discharging opening is prevented from being blocked, meanwhile, the tower body is convenient to clean, and manpower is saved.

Description

technical field [0001] The invention relates to the technical field of desulfurization towers, in particular to a coke oven gas desulfurization tower. Background technique [0002] The equipment for desulfurization treatment of industrial waste gas is mostly tower equipment, which is the desulfurization tower. The desulfurization tower was originally built with granite masonry and was the most widely used. It uses the principle of water film desulfurization and dust removal, also known as granite water film desulfurization dust collector, or granite water film desulfurization dust collector. Dust removal agent, achieve the effect of dust removal and desulfurization (denitrification) at the same time. [0003] In the process of realizing the present invention, it is found that at least the following problems in the prior art have not been solved: the coal gas enters the coke oven gas desulfurization tower, the thick slurry reacts with the sulfur dioxide in the gas, and at th...

Problems solved by technology

[0003] In the process of realizing the present invention, it is found that at least the following problems in the prior art have not been solved: the coal gas enters the coke oven gas desulfurization tower, the thick slurry reacts with the sulfur dioxide in the gas, and at this time, some solid particles in the gas will adhere to the desulfurization tower The inner surface of the tower body will accumulate in the tower body for a long time, which will cause corrosion inside the tower body and damage the desulfurization tower. After cleaning the inner surface of the tower body, the attached solid particles will fall into the slurry at the lower end of the tower body. When the slurry at the lower end of the tower is discharged from the tower body, the falling solid particles will block the slurry discharge port, resulting in unsmooth discharge of the slurry and affecting the normal operation of the desulfurization tower
