An integrated tower for dust removal, desulfurization and denitrification

Abstract

The invention discloses a dust removal, desulfurization and denitrification integrated tower in the field of flue gas desulfurization and denitrification, comprising a tower body and a tower cover, a first connecting screw hole is opened in the center of the bottom end of the tower body, and the inner wall of the tower is fixedly arranged sequentially from bottom to top. For the first partition, the second partition and the third partition, there is an opening at the bottom of the side wall of the tower body, and the opening is closed by a sealing plug. The first connecting screw hole is internally threaded with a first one-way valve. The flue gas pipe is connected to the end of the valve, the top of the first partition is evenly opened with ventilation holes, the center of the second partition is provided with a through hole, the center of the top of the second partition is fixedly installed with the SCR reactor, the SCR reactor and the through hole The top center of the SCR reactor is provided with an outlet pipe, the center of the top of the third partition is provided with a second connecting screw hole, the top of the third partition is placed with a liquid cylinder, and the center of the bottom of the liquid cylinder is provided with a through hole, and the through hole is installed There is a second one-way valve, the side wall of the second one-way valve is threadedly matched with the second connecting screw hole, and an air outlet is opened in the center of the top of the tower cover.

Description

technical field [0001] The invention relates to the field of flue gas desulfurization and denitrification, in particular to an integrated tower for dust removal, desulfurization and denitrification. Background technique [0002] my country's coal resources contain a lot of high-sulfur coal. According to incomplete statistics, about 13% of the resource coal in the country has a sulfur content higher than 2%, and the coal contains a large amount of C, H, S, N and other elements. Therefore, the coal directly Combustion and emission of a large amount of pollutants has caused serious soot-type pollution in my country's atmospheric environment, which has caused great harm to natural ecology and human beings. Among them, sulfide and nitrogen compounds are the most serious, which are harmful to the natural environment and human life. The loss and harm caused are the most serious. The boiler flue gas needs to be desulfurized and denitrified before being discharged. The flue gas desulfu...
