Joining type variable speed ultrafine particle coagulation tank

Abstract

The invention discloses a joining type variable speed ultrafine particle coagulation tank. The whole coagulation tank is a tank type and is suitable for being installed between an electric deduster and a bag deduster, the coagulation tank comprises a gas inlet, a gas outlet, a coagulation zone and ash buckets, the gas inlet is a channel behind the electric deduster, the flue gas comes from the electric deduster, the coagulation zone is provided with wave-shaped partition plates, the dust particle is strengthened and coagulated in a channel between the wave-shaped partition plates, the gas outlet is formed in the lower part of the coagulation zone and above the ash buckets to be arranged into an overflowing channel, an adsorbent like activated carbon, a coagulation accelerant and the like pass through a drainage tube and are sprayed into the coagulation zone through a spraying nozzle, and the coagulated flue gas enters the bag deduster to be treated. The joining type variable speed ultrafine particle coagulation tank is strongly targeted and is wide in applicable range, optimized in structure, and high in reliability.

Description

technical field [0001] The invention belongs to the field of flue gas dedusting treatment, and relates to an intersection-type variable-speed superfine particle coagulation box. Background technique [0002] In recent years, there have been more and more smog weather in large and medium-sized cities in my country, which has seriously affected the healthy work and life of urban residents. Among them, PM in the urban environment 2.5 (mainly PM 0.4-1.0 ) content is too high is the main cause of haze weather. Therefore, how to control PM 2.5 Generation, and reduce its existence, has become an urgent problem to be solved. [0003] Chinese patent CN101664623A discloses a fine particle dust collector for industrial smoke control. Specifically, a turbulent vortex mechanism is provided between the outlet of the filter bag dust removal mechanism and the inlet of the induced draft fan through the improvement of the electric bag composite dust collector of the existing two-stage fil...

AI Technical Summary

Problems solved by technology

[0005] The above process equipment, the method is complicated, the control operation is difficult, the equipment investment and operation cost are high

[0006] Therefore, in view of the problems of low coagulation efficiency and complex process equipment, it is necessary to research and develop ultra-fine particle coagulation boxes that strengthen coagulation on the basis of existing technologies.
