Suspension-type purifying equipment

Abstract

The invention discloses suspension-type purifying equipment. The suspension-type purifying equipment comprises a denitration device, a dilution water pressure control device is arranged on a denitration device body, a water injection opening is formed in the left end of the dilution water pressure control device, the dilution water pressure control device is connected with a supplying circulatingdevice, a urea storage tank is arranged at the other end of the supplying circulating device, a urea unloading pump is arranged at one connecting end of the urea storage tank, a pipe is arranged at the left end of the urea unloading pump, one connecting port of the right end of a gauge is connected with an averaging device, a boiler is arranged at the other end of the averaging device, an injectoris arranged on one side of the boiler, an air compressor is arranged at the left end of the injector, the left end of the boiler is connected with a demisting dedusting device, a cooling filtering net and a magnetic-force adsorption mechanism are arranged in the demisting dedusting device, and auxiliary mechanical arms for reloading are arranged on the two sides of the cooling filtering net. According to the smoke denitration device, denitration efficiency can be improved, a filter element can be replaced on line, frictional force of replacement is small, efficiency is high, and the speed ishigh.

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
