Desulfurization tower for production of grey tiles

Abstract

The invention discloses a desulfurization tower for production of grey tiles. The desulfurization tower comprises a desulfurization tower body and is characterized in that a fan is mounted on the side, close to the desulfurization tower body, of the inner wall of a dust collecting box, a dust collecting cloth bag is arranged on the side, close to a flue gas inlet, of the inner wall of the dust collecting box, a water outlet of the desulfurization tower body is connected with a flow dividing pipe, the bottom ends of a first spraying pipe and a second spraying pipe are connected with atomizationspraying heads correspondingly, and the desulfurization tower body is internally provided with a water-gas separation layer, an activated carbon layer and a baffle in sequence from top to bottom. According to the desulfurization tower, flue gas is absorbed into the dust collecting box through the fan, particulate dust in the flue gas is blocked and filtered through the dust collecting cloth bag,plugging of the desulfurization tower body and the spraying pipes are prevented, and absorbing liquid is pumped through by a desulfurization pump and sprayed out fromof the atomization spraying headsthrough the first spraying pipe and the second spraying pipe, and to absorb thus sulfur dioxide in the flue gas is absorbed; and through the arranged baffle, the flue gas forms an S-shaped route in the desulfurization tower body, the residence retention time of the flue gas in the tower body in increased, and the desulfurization efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of desulfurization towers, in particular to a desulfurization tower for green tile production. Background technique [0002] The desulfurization tower is a tower-type equipment for desulfurization treatment of industrial waste gas. 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. dust collector. [0003] In the production of blue tiles, the combustion of coal will produce flue gas with sulfur dioxide. When using a desulfurization tower for desulfurization, the flue gas stays in the tower for a short time, resulting in the absorption liquid cannot be completely absorbed, and the exhausted flue gas contains the absorption liquid. Moisture, low desulfurization efficiency, and the particles in the flue gas usually block the desulfurization pump and spray pipe, which is troublesome to clean. The...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of desulfurization tower for the production of blue tiles, to solve the above-mentioned background technology in the production of blue tiles because the combustion of coal can produce flue gas with sulfur dioxide, when using the desulfurization tower for desulfurization, the flue gas The residence time in the tower is short, so that the absorption liquid cannot be completely absorbed, and the exhausted flue gas contains moisture in the absorption liquid, the desulfurization efficiency is low, and the particles in the flue gas usually block the desulfurization pump and spray pipe, which is troublesome to clean, and the metal substrate The inner wall of the desulfurization tower and its protective layer have been washed away by the high-velocity, high-solid-content slurry for a long time, resulting in erosion corrosion, perforation, and low service mission.
