Dust removal and desulphurization tower

Abstract

The invention belongs to the technical field of waste gas cleaning, and specifically discloses a dust removal and desulphurization tower. The dust removal and desulphurization tower comprises a dust removing tower and a desulphurization tower, wherein the desulphurization tower comprises an outer tower and an inner tower; an air channel is formed between the inner tower and the outer tower; an annular sliding plate is glidingly connected to the air channel; a first spray head is arranged in the inner tower; a second spray head is arranged in the outer tower; a communication pipe which is communicated with the upper part of the inner tower is connected to the dust removing tower; a motor and a transmission shaft are arranged at the upper part of the dust removing tower; a cam is fixed to the transmission shaft; a first piston barrel is arranged at the lower part of the cam; a first piston is glidingly connected into the first piston barrel; a first pushing rod is fixed to the first piston; a dust removing mechanism is arranged in the dust removing tower; a pushing plate is glidingly connected into the dust removing tower; a second piston barrel is arranged below the pushing plate; asecond piston is glidingly connected into the second piston barrel; a second pushing rod is fixed to the second piston; a single-control switch and a third piston barrel are arranged in the dust removing tower. The dust removal and desulphurization tower is simple in inner structure, and is capable of fully performing desulphurization.

Description

technical field [0001] The invention belongs to the technical field of waste gas purification, and in particular relates to a dust removal and desulfurization tower. Background technique [0002] my country is a large coal-fired country. Tens of millions of tons of smoke and dust are discharged from various coal-fired boilers every year. These untreated dust-containing and sulfur-containing flue gases are directly discharged into the atmosphere, which is the main cause of air pollution, especially It is the sulfur oxide contained in coal-fired flue gas, which is discharged into the atmosphere and combines with water vapor in the atmosphere to form acid rain, pollute land, water sources, cause serious damage to industry, agriculture and the ecological environment, and also endanger people's health . For this reason, the coal-fired boiler flue gas emission standards formulated by governments of various countries have made more and more stringent limits on the content of sulfur ...

AI Technical Summary

Problems solved by technology

[0004] At present, dust removal and desulfurization towers are generally used to remove dust and desulfurize sulfur-containing flue gas. Due to the fast flow of sulfur-containing gas, the contact time between absorbent and sulfur-containing gas is short, and it is difficult to fully desulfurize with one spray. In order to ensure desulfurization efficiency, It is often necessary to set up multi-layer spraying in the dust removal and desulfurization tower, which makes the internal structure of the dust removal and desulfurization tower too complicated
