A desulfurization and dust removal equipment with a limit switch

Abstract

The invention relates to desulfurization and dedusting equipment with a limit switch. The desulfurization and dedusting equipment comprises a tank body (1), wherein the tank body (1) is divided into an upper main body part and a lower sediment cone part (6), the cross section of the upper main body part is of a square quadrangular prism shape, the cross section of the lower sediment cone part (6) is of a square quadrangular frustum pyramid shape, a smoke outlet (2) is formed at the top end of the upper main body part, a sediment outlet is formed at the bottom end of the lower sediment cone part (6), an outlet valve (7) is arranged at the position of the sediment outlet, a circulating alkaline liquid outlet pipe (4) is arranged at the parting position of the main body part and the sediment cone part, an alkaline liquid input spraying pipe (3) is arranged at a position of the main body part, close to the top end, a smoke inlet pipeline (5) is arranged at the lower middle part of the main body part, and an operable spraying blocking 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 limit switch. 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 equ...

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
