Dual-tower dust removal and desulphurization device

Abstract

The invention discloses a dual-tower dust removing desulphurization device which comprises a main tower. A flue gas inlet is formed on the main tower, a sprayer is arranged on the top side of the main tower, the upper end of the main tower is sealed, a liquid discharge hole is formed at the lower end, twin towers are inserted to the bottom part in the main tower from the upper end of the main tower and provided with communicating holes to communicate with the main tower, the upper ends of the twin towers communicate with a top tower, a sub-tower sprayer and a sub-tower defogger are arranged in the twin towers, a top tower sprayer and a top tower defogger are arranged in the top tower, and a flue gas outlet is formed on the top tower. The dual-tower dust removing desulphurization device has the following advantages: as the dual-tower dust removing desulphurization device adopts the structure of twin towers, the dual-tower dust removing desulphurization device can carry out the dust removing desulphurization treatment of flue gas emitted by a large-scale coal-fired boiler, the dust removing desulphurization efficiency is high, the coal-fired flue gas after the treatment can achieve the requirements of the environmental protection emission; furthermore, the structure is simple, the operation cost is low and the environmental protection benefits are very good.

Description

technical field [0001] The invention relates to a flue gas dust removal and desulfurization device. 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 . At present, the dust removal and desulfurization devices for coal-fired flue gas at home and abroad have the following disadvantages: first, the process equipment is complicated and the cost is high; second, the efficiency of dust removal and des...

AI Technical Summary

Problems solved by technology

At present, the dust removal and desulfurization devices for coal-fired flue gas at home and abroad have the following shortcomings: first, the process equipment is complicated and the cost is high; second, the efficiency of dust removal and desulfurization is not high, and it is only suitable for small and medium-sized coal-fired boilers; High, not conducive to promotion and use
