Multistage dust removing environment-friendly device for flue gas

Abstract

The invention discloses a multistage dust removing environment-friendly device for flue gas. A metal mesh disc can intercept large-particle dust in the flue gas to the upper part of the metal mesh disc; the metal mesh disc is driven to rotate when a motor starts, and the large-particle dust on the metal mesh disc rotates to a left side along with the metal mesh disc; the dust on the metal mesh disc enters a dust removing pipe and finally enters a storage cylinder because of a scraping effect of an arc-shaped scraping plate on the dust on the metal mesh disc; the storage cylinder is in screwedconnection with the dust removing pipe, so that the detaching and the cleaning of the storage cylinder are facilitated; filtered gas overflows through gas outlets in a conical cover; part particle dust and harmful substances in the overflowed gas are adsorbed by water; the gas enters above a water surface and is in further contact with a water curtain because of the effect of a spraying device, sothat the adsorption effect is improved; because of the effects of a ceramic mesh hole plate and wet sponge, the adsorption effect to the gas is further enhanced, and the dust removing effect on the flue gas is obvious.

Description

technical field [0001] The invention relates to the technical field of flue gas treatment, in particular to a multi-stage dust removal environmental protection device for flue gas. Background technique [0002] The water bath dust collector is a wet dust collector that makes the dusty gas fully bathe in water. It is widely used because of its simple structure and low cost. When the dust-laden gas with a certain speed is ejected at a relatively high speed through the intake pipe at the nozzle, it impacts the water layer and enters the liquid, changing the direction of movement of the gas, while the dust particles continue to follow the original direction due to the inertial force. movement, in which most of the dust particles remain in the liquid after adhering to the water. During this process, the dust particles in the dusty gas are captured by water, the dusty water droplets in the purified gas are separated from the air flow by the dehydration device, and the clean gas i...

AI Technical Summary

Problems solved by technology

The accumulation of dust particles in the dedusting liquid will form a layer of dirt, which needs to be discharged after the dedusting liquid can be cleaned, which wastes a lot of labor and is inefficient

[0003] For this reason, the Chinese patent (authorized announcement: CN205796821U) discloses an environmentally friendly water bath dust collector. Although the dust collector can perform dust removal, it does not have the function of multi-stage dust removal, and it is inconvenient for dust collection and cleaning.
