Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization spray towers, in particular to a flue gas flow equalization mechanism and a desulfurization spray tower. Background Art

[0002] Desulfurization spray tower is a kind of equipment widely used in the field of flue gas desulfurization. Its main function is to spray the desulfurizer evenly on the packing layer through the spray device, so that harmful substances such as sulfur dioxide in the flue gas react with the desulfurizer, thereby achieving the purpose of removing harmful substances. The desulfurization spray tower has a reasonable structural design and is easy to operate. It can effectively remove harmful substances in the flue gas and meet national emission standards.

[0003] The flue gas flow equalization mechanism is designed to solve the problem of uneven flue gas flow. In the process of flue gas treatment, if the flue gas flows unevenly, the treatment effect will be reduced or even the treatment equipment will be damaged. Therefore, the design of the flue gas flow equalization mechanism is very important. It may adopt various structures, such as guide plates, flow equalization reactor structures, etc., to ensure that the flue gas is evenly distributed during the flow process, thereby improving the efficiency and effect of flue gas treatment.

[0004] When the existing flue gas equalizing mechanism processes the flue gas entering the desulfurization spray tower, the flue gas is diverted through the guide plate in the flue gas equalizing mechanism. However, when the diversion only relies on the guide plate, the part where the center of the guide plate is in direct contact with the flue gas cannot disperse the flue gas well, resulting in the flue gas concentration in the center of the guide plate being greater than the flue gas concentration at the edge of the guide plate.
