Sulfur-fixation denitration dust removal device

Abstract

The invention provides a sulfur fixation, denitrification and dust removal device, which includes a box body with a smoke inlet, a flue gas cooling pipe, and a main smoke exhaust pipe. The box body is provided with a partition, and the partition board divides the box body into a cooling water tank. and a dust removal bin; the dust removal bin is provided with a dust removal water tank, and the flue gas cooling pipe is located in the cooling bin; the upper nozzle of the flue gas cooling pipe is provided with a sealing cover, and the lower nozzle of the flue gas cooling pipe is an open type , the upper end of the flue gas cooling pipe is provided with an air inlet, and the lower end of the flue gas cooling pipe is placed on the partition; the lower pipe openings of the main exhaust pipe and the flue gas cooling pipe are connected with the dust removal water tank. The invention has the advantages of simple structure, low operation cost, good effect of sulfur fixation and dust removal, and effectively solves the problem of environmental pollution caused by flue gas discharge from combustion boilers.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment and relates to a dust removal device, in particular to a sulfur fixation, denitrification and dust removal device. Background technique [0002] Coal is the main source of energy in my country. Coal combustion will produce a large amount of pollutants. Among them, dust particles and fine dust PM2.5, which have a greater impact on human health, are likely to induce respiratory diseases and are also the main cause of urban smog. . At present, most of the existing dust removal technologies and equipment do not have the function of sulfur fixation and denitrification, and it is difficult to adapt to the current environmental pollution, especially the control of PM2.5, which has become an urgent problem to be solved. [0003] The flue gas cooling pipe used in the traditional dust removal device is open-ended at both ends. The flue gas enters from one end of the cooling pipe and is disc...

Problems solved by technology

At present, most of the existing dust removal technology and equipment do not have the function of sulfur fixation and denitrification, and it is difficult to adapt to the current environmental pollution, especially the control of PM2.5, which has become an urgent problem to be solved

[0003] The flue gas cooling pipe used in the traditional dust removal device is open-ended at both ends. The flue gas enters from one end of the cooling pipe and is discharged from the other end. It is only cooled by external cooling water. The cooling effect is poor and the flue gas is easy to flow backward, and the dust removal effect is not ideal.
