Desulfurization and denitrification integrated purification system

Abstract

A disclosed desulfurization and denitrification integrated purification system comprises a base, a desulfurization tank body, a denitrification tank body, a purification tank body and a purification box body, a support is fixedly connected to the top of the right side of the base, the desulfurization tank body is fixedly connected to the top of the support, and a transmission pipe is fixedly connected to the right side of the desulfurization tank body; a denitration tank body is arranged on the side, away from the desulfurization tank body, of the conveying pipe, an ion purification pipe is fixedly connected to the bottom of the right side of the denitration tank body, a purification tank body is fixedly connected to the side, away from the denitration tank body, of the ion purification pipe, and a flue gas conveying pipe is arranged on the top of the purification tank body; the side, away from the purification tank body, of the flue gas conveying pipe is fixedly connected with a purification box body, the desulfurization tank body, the denitration tank body, the purification tank body and the purification box body are arranged, so that the flue gas subjected to desulfurization and denitration treatment can be subjected to impurity separation treatment, the phenomenon of incomplete treatment is avoided, and a conical net is arranged in an inner cavity of the desulfurization tank body; therefore, better purification and filtration can be realized.

Description

technical field [0001] The invention relates to the technical field of desulfurization and denitrification integrated purification, in particular to a desulfurization and denitrification integrated purification system. Background technique [0002] The flue gas emitted by coal-fired power plants and industrial furnaces contains a large amount of harmful gases such as SO2 and NOX, which seriously affects the human living environment and economic development. Measures must be taken to purify the flue gas and control air pollution. Traditional coal-fired power plants The waste gas after coal combustion is directly discharged into the atmosphere after dust removal, desulfurization and denitrification are close to or meet the emission standards, and some of them have not yet reached the standard. The exhaust gas contains sulfur dioxide, nitrogen dioxide, nitrogen monoxide and other harmful gases. And fine solid impurity dust such as fly ash with light specific gravity and small p...

[0002] The flue gas emitted by coal-fired power plants and industrial furnaces contains a large amount of harmful gases such as SO2 and NOX, which seriously affects the human living environment and economic development. Measures must be taken to purify the flue gas and control air pollution. Traditional coal-fired power plants The waste gas after coal combustion is directly discharged into the atmosphere after dust removal, desulfurization and denitrification are close to or meet the emission standards, and some of them have not yet reached the standard. The exhaust gas contains sulfur dioxide, nitrogen dioxide, nitrogen monoxide and other harmful gases. And fine solid impurity dust such as fly ash with light specific gravity and small particles, the amount of sulfur dioxide discharged after 75 tons of coal is burned in the boiler can reach 10 tons per day, these sulfur dioxide, nitrogen oxides and fine particles are formed The main killer of smog will greatly affect the health of residents and even threaten their lives

[0003] The common denitrification and desulfurization is a split type, which not only occupies a large space, but also has cumbersome processing steps, and the gas after denitrification and desulfurization is directly discharged, and the solid impurities generated in it are difficult to separate and discharge in time, resulting in incomplete treatment.
