A suspended purification device

Abstract

The invention discloses a suspension purification device, which has a denitrification device. A dilution water pressure control device is provided on the denitrification device body. A water injection port is provided at the left end of the dilution water pressure control device. The dilution water pressure control device is connected to a supply circulation device. The other end of the supply circulation device is provided with a urea storage tank, one connection end of the urea storage tank is provided with a urea unloading pump, the left end of the urea unloading pump is provided with a pipeline, and a connection port at the right end of the meter is connected to the equalizer, and the equalizer The other end of the boiler is equipped with a boiler, one side of the boiler is equipped with an injector, and the left end of the injector is equipped with an air compressor. The left end of the boiler is connected to a demist and dust removal device. Both sides of the cooling filter are equipped with auxiliary mechanical arms for replacement. The flue gas denitrification device of the present invention can improve the denitrification efficiency, and can replace the filter element on-line, with small replacement friction, high efficiency and fast speed.

Description

technical field [0001] The invention relates to the technical field of environmental protection and denitrification, in particular to a suspension type purification equipment. Background technique [0002] The harm of nitrogen oxides in flue gas to environmental pollution has been sharply raised as a worldwide problem. In recent years, China's NOX emissions have increased significantly. In view of the adverse effects of NOX on the atmospheric environment and the current severe situation of NOX emission control, my country has formulated more stringent emission standards. [0003] China is a country where coal is the main energy source. Coal accounts for 75% of the primary energy, and more than 84% of it is used through combustion. The nitrogen oxides (NOx) in the exhaust gas released by coal combustion are the main atmospheric pollutants. one of the sources of pollution. Selective catalytic reduction is the most common and effective method for removing nitrogen oxides from...

Problems solved by technology

[0004] Among them, the flue gas has a relatively high temperature, which is harmful to the environment. The existing equipment is generally cooled when it is discharged into the atmosphere, which is not conducive to the miniaturization of the equipment, and the flue gas has particulate dust, which affects the subsequent SCR denitrification reactor. Disposal, easy to clog, need to be shut down for replacement
