Central air purification dust removal system

Abstract

The invention discloses a central air purification dust removal system. The central air purification dust removal system comprises a desulfuration dust removal tower. A smoke inlet is formed in the lower portion of the desulfuration dust removal tower, and a smoke outlet is formed in the upper portion of the desulfuration dust removal tower. The central air purification dust removal system further comprises a lime water tank and a settling tank. A sprayer is arranged on the upper portion in the desulfuration dust removal tower, filler layers distributed at intervals in a staggered mode are arranged at the position, located below the sprayer, in the desulfuration dust removal tower, the lime water tank and the sprayer are connected through a lime water pipeline, an exhaust pipeline communicated with the interior of the settling tank is arranged at the bottom of the desulfuration dust removal tower, and a supernatant recovery pipeline communicated with the interior of the lime water tank is arranged on the upper portion of the settling tank. The central air purification dust removal system is very suitable for being used under the working conditions that the smoke exhaust amount of industrial waste gas is large and the smoke flow speed is high, dust and sulfur dioxide in smoke can be efficiently removed, the smoke can be exhausted cleanly, installation and use are convenient, and cost can be reduced.

Description

technical field [0001] The invention relates to a central air purification and dust removal system, in particular to an air purification system for simultaneously removing sulfur dioxide and dust in waste gas, and belongs to the technical field of environmental protection equipment. Background technique [0002] With the continuous increase of industrial waste gas emissions in our country, the problem of air pollution has become increasingly prominent. Industrial flue gas contains a large amount of dust and sulfur oxides. Therefore, desulfurization and dust removal equipment is generally used in the field of waste gas treatment to desulfurize and remove industrial waste gas. . There is a wet electrostatic precipitator in the prior art, which can remove dust, sulfur dioxide and aerosol in the flue gas. Wet electrostatic precipitators can be divided into tube type and plate type dust collectors according to the different electrode forms, and their arrangement can be divided i...
