Abstract

The invention discloses a desulfurization and denitrification device which comprises a reaction tower, a gas outflow top cover is arranged at the top of the reaction tower, a discharge groove is formed in the outer side of the top of the gas outflow top cover, a gas inflow pretreatment device is arranged on the right side of the reaction tower, a gas inflow pipe is arranged at the top of the gas inflow pretreatment device, a reflux reaction tank is arranged on the left side of the outer part of the reaction tower, the upper end and the lower end of the reflux reaction tank are communicated with the reaction tower through gas guide pipes, a desulfurization and denitrification reaction tank is mounted in the reflux reaction tank, and the gas guide pipe above the reflux reaction tank extends into the desulfurization and denitrification reaction tank. The invention belongs to the technical field ofdesulfurization and denitrification. According to the desulfurization and denitrification device, rapid desulfurization and denitrification of flue gas in the device can be guaranteed through multiple reactions, the reactions are more thorough, solution bubbles are increased, the reaction volume is enlarged, the reactions are accelerated, and the problems that a desulfurization device is low in purification speed and the desulfurization and denitrification reaction is not thorough enough are solved.

Description

technical field [0001] The invention relates to the technical field of desulfurization and denitrification, in particular to a desulfurization and denitrification device. Background technique [0002] When coal-fired boilers are burning, various organic and inorganic sulfur contained in coal are converted into sulfur oxides mainly sulfur dioxide, which enters the atmosphere and combines with water in the atmosphere to form acid rain, which not only affects ground buildings and crops Seriously affect human health, so flue gas desulfurization is an important part of environmental protection. The main method of flue gas desulfurization is wet desulfurization, which uses limestone and other slurries as detergents to wash the flue gas in the reaction tower to absorb sulfur dioxide in the flue gas. The flue gas wet, semi-dry, and dry flue gas desulfurization devices have been developed rapidly in various industries in my country, but the existing flue gas desulfurization devices ...
