Desulfurization and dust removal equipment

Abstract

The invention discloses desulfurization and dust removal equipment which comprises a tank body (1), wherein the tank body (1) is divided into a main body part on the upper part and a sediment cone part (6) on the lower part; the main body part on the upper part is in the shape of a regular quadrangular prism of which the section is square; the sediment cone part (6) on the lower part is in the shape of a regular quadrangular frustum pyramid of which the section is square; a flue gas outlet (2) is formed in the top of the main body part on the upper part; a sediment outlet is formed in the bottom end of the sediment cone part (6) on the lower part; an outlet valve (7) is arranged at the sediment outlet; a circulating alkaline liquor outlet pipe (4) is arranged at the joint of the main body part and the sediment cone part; an alkaline liquor input spray pipe (3) is arranged at a position, which is close to the top end, of the main body part; a flue gas inlet pipeline (5) is arranged at a position, which is close to the lower part of the middle, of the main body part; and an operable spraying barrier device (9) is arranged above the sediment cone part (6) in the tank body (1).

Description

technical field [0001] The invention belongs to the field of desulfurization and dust removal, in particular to a desulfurization and dust removal equipment with a blocking device. Background technique [0002] Desulfurization and dust removal equipment often use desulfurization and dust removal towers for water film or water mist desulfurization and dust removal, and add desulfurization agents, such as alkaline substances, to the water to achieve the purpose of desulfurization and dust removal at the same time. Lye can be recycled. After the desulfurization and dust removal, the lye is mixed with the slag or sediment formed, which precipitates in the precipitation part and is separated and discharged. The lye is circulated by the pump after the slag is separated. [0003] The precipitated sediment needs to be cleaned and discharged regularly. However, when cleaning, it often takes a certain amount of time. At this time, in order not to affect the normal operation of the ...

Problems solved by technology

However, when cleaning, it often takes a certain amount of time. At this time, in order not to affect the normal operation of the equipment, the sprinkler system works normally, which will cause a large amount of lye to flow out along with the discharge of the sediment, which will bring great harm to the discharge of the sediment. Trouble, such as the need to separate large volumes of liquid again; and this creates waste of lye and the potential for possible environmental pollution
