Automatic scraper wet dust collector

General introduction: An automatic scraper wet dust collector is a dust removal equipment that uses water as the medium and is assisted by a scraper mechanism, which is mainly used to remove dust particles from industrial waste gas.

Detailed introduction is as follows:

Working Principle

Flue gas is drawn into the natural flue by the induced draft fan and enters the flue gas acceleration chamber inside the dust removal box through the smoke outlet. Since the cross-sectional area of the acceleration chamber is smaller than that of the natural flue, high-speed airflow is generated by self-excitation phenomenon. The high-speed airflow drives flue gas into the water pool rapidly, and a large number of dust particles are separated and settled underwater relying on water adhesion. The separated flue gas flows into the deceleration chamber with a larger cross-sectional area for buffering, and then enters the next acceleration chamber to repeat the purification process. Finally, the purified flue gas is discharged into the atmosphere through the dust removal smoke outlet and natural flue.

Advantages

High dust removal efficiency: The self-excitation principle enables flue gas to contact with water for multiple times to separate dust particles efficiently, leaving low dust content in purified flue gas.

Water resource saving: The water in the pool can be recycled, reducing water waste compared with wet spray dust collectors.

Easy cleaning: The dust removal box and water pool adopt inverted quadrangular frustum structure tapered from top to bottom, which prevents fine dust deposition on the inner wall and facilitates cleaning.

Application Scope

With the advantages of wet dust removal and automatic slag cleaning, the equipment is suitable for industrial flue gas with high dust concentration, strong viscous dust and continuous operation requirements.

Mining and mineral processing industry: Treat high-concentration waste gas generated during ore crushing, screening and transportation. The automatic scraper removes viscous mineral slag to prevent pool blockage.

Metallurgical industry: Applied to flue gas treatment of blast furnace tapping, steelmaking converter and non-ferrous metal smelting. It realizes dust removal and cooling, ensuring continuous equipment operation.

Building materials industry: Purify dust waste gas from cement clinker crushing, ceramic raw material grinding and gypsum board production. It reduces manual maintenance frequency through automatic slag removal.

Chemical industry: Suitable for dust generated during chemical raw material crushing and mixing. Corrosion-resistant materials are matched to neutralize slightly corrosive dust.

Machining industry: Treat metal dust and molding sand dust from casting, sand blasting and polishing processes, adapting to intermittent dust generation conditions.

Precautions

It is not applicable to dust with strong hydrophobicity and easy scaling and hardening in case of water, so as to avoid scraper stagnation and pool scaling.

It cannot handle flue gas containing flammable and explosive components, preventing explosive mixtures formed by water vapor and combustible gas.
