Desulfurization and dedusting equipment with air intake system

Abstract

The invention relates to desulfurization and dedusting equipment with an air intake system. 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 tapered body part (6), and the upper main body part is a regular quadrangular body with a square section; the lower sediment tapered body part (6) is a quadrangular frustum pyramid with a square section, and a flue gas outlet (2) is formed in the top end of the upper main body part; a sediment outlet is formed in the bottom end of the lower sediment tapered body part (6), and an outlet valve (7) is arranged at the sediment outlet; a circulating lye outlet pipe (4) is arranged at the boundary of the main body part and the sediment tapered body part, and a lye input spraying pipe (3) is arranged at a part, close to the top end, on the main body part; a flue gas inlet pipeline (5) is arranged at a part, close to the lower part, in the middle of the main body part, and is provided with the air intake system close to the tank body (1), and an operable spray blocking device (9) is arranged above the sediment tapered body 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 an air inlet system. 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 th...

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
