Desulphurization and dust removal equipment capable of dissipating heat through water

Abstract

Desulphurization and dust removal equipment capable of dissipating heat through water comprises a tank (1), wherein the tank (1) is divided into an upper main body part and a lower sediment cone part (6), the upper main body part is in a regularly quadrangular prism shape with the square section, the lower sediment cone part (6) is in a regularly quadrangular frustum shape with the square section, a flue gas outlet (2) is arranged at the top end of the upper main body part, a sediment outlet is arranged at the bottom end of the lower sediment cone part (6), and an outlet valve (7) is arranged at the sediment outlet; a circulating alkaline liquid outlet pipe (4) is arranged in a dividing position of the main body part and the sediment cone part, an alkaline liquid input spray pipe (3) is arranged in a position, close to the top end, of the main body part, a flue gas inlet pipeline (5) is arranged in a middle-lower position of the main body part, and an operable spray blocking device (9) is arranged above the sediment cone part (6) and in the tank (1).

Description

technical field [0001] The invention belongs to the field of desulfurization and dust removal, and in particular relates to a desulfurization and dust removal equipment that dissipates heat through water. Background technique [0002] Desulfurization and dust removal equipment that uses water to dissipate heat often use desulfurization and dust removal towers to perform 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. ...

AI Technical Summary

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
