Efficient wet desulphurization and dust removal combined treatment device

Abstract

The invention discloses an efficient wet desulphurization and dust removal synergistic treatment device which is of a tower body structure, and the interior of a tower body is divided into an absorption section, a washing section and a demisting and dust removal section from bottom to top; the absorption section comprises a flue gas inlet (3), a tower bottom slurry tank (1), a spraying device (4), a tower plate (5), a gas lifting cap and a first circulating pump (2); the washing section comprises a washing device (7) and a second circulating pump (6); and the demisting and dedusting section comprises a demister (8), a cleaning device, a wet bag type dust collector (9), a dust collector ash removal device (11) and a flue gas outlet (10). According to the invention, the emission index that SO2 is less than or equal to 35mg / Nm can be achieved, and the treatment effect that dust emission is even less than or equal to 5mg / Nm can be achieved; the flue gas purification effect is ensured, and the ultralow emission index is ensured to be realized.

Description

technical field [0001] The invention belongs to the technical field of industrial flue gas desulfurization and dust removal treatment, and in particular relates to a high-efficiency wet desulfurization cooperative dust removal treatment device. Background technique [0002] As we all know, my country is a country with more coal and less oil, and coal resources are an important part of my country's energy. In 2016, my country's coal power generation accounted for more than 60%, and the power generation accounted for more than 70%, which shows the important position of coal in my country's energy structure. Industrial boilers in chemical industry, electric power, coking, smelting, carbon, manufacturing and other industries are mainly coal-fired. SO 2 Harmful components such as nitrogen oxides and nitrogen oxides are the chief culprits of acid rain and smog that destroy the ecological environment, seriously affecting the sustainable development of my country's economic societ...

Problems solved by technology

[0004] The traditional process is mostly carried out in desulfurization and dust removal step by step, so as to realize joint desulfurization and dust removal. This hierarchical treatment method has the disadvantages of large area occupation, high investment and operation costs, and SO 2 , aerosol particles, dust, soluble pollutants and other pollutants removal efficiency is not ideal and many other disadvantages
