A wet cyclone dust collector for recycling washing liquid

Abstract

The invention discloses a wet type cyclone dust collector with a washing liquid recycling function. The wet type cyclone dust collector with the washing liquid recycling function comprises a sprayingdevice, a gas-liquid coupler, a Venturi tube and a cyclone dust collection structure; the spraying device comprises a spraying drum, a spraying pipe, a spraying head and a washing liquid containing barrel arranged outside the spraying drum; the spraying drum is in a bent shape, an air blower is arranged on the side wall of the spraying drum, and an air inlet is formed in the top of the spraying drum; the gas-liquid coupler comprises a first contraction section, a flat section and a first expansion section; the Venturi tube comprises a second contraction section, a throat portion and a second expansion section; the cyclone dust collection structure comprises a reverse-flow type cone separator body, a cyclone top board and a dust discharging drum; internal rotary airflow and external rotaryairflow are introduced into the reverse-flow type cone separator body; and a washing liquid recycling structure is arranged between an exhaust port and the washing liquid containing barrel. A large amount of dust adhering to washing liquid is subjected to cyclone separation and removal, low-boiling components in the washing liquid can be heated and evaporated and can continue to be recycled and sprayed after being condensed, the dedusting cost is reduced, and the dedusting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of environmental protection dust removal equipment, in particular to a wet cyclone dust collector for recycling washing liquid. Background technique [0002] At present, domestic gas dedusting technologies mainly include electric dust removal, bag dust removal, wet dust removal, mechanical dust removal, etc. Electric dust removal and bag dust removal have the disadvantages of large area occupation, high cost, and high operating cost; the dust removal efficiency of mechanical dust removal is low. higher precision requirements. In order to make up for the defects of various methods, there is a dust removal device combining several methods in the prior art, but the cost is high, the structure is complicated, and the operation cost is high. [0003] Industrial production activities will lead to the generation of smoke and dust. Ceramic processing factories, stone factories, power plants, etc. all need to instal...

AI Technical Summary

Problems solved by technology

However, due to different washing liquid components, such as water, lye, and acid, the components with low boiling points will enter the ash discharge tube together with the dust after washing the dust in the flue gas, so that the humidity in the cyclone separator will increase. , the humidity of the exhausted flue gas is high, which reduces the dust removal efficiency

In addition, dust is mixed with a large amount of liquid components, and washing liquid needs to be continuously added after centralized dumping treatment, which wastes resources and increases the cost of dust removal
