Venturi wet dust Collector – water dust removal

Venturi wet dust collector belongs to a kind of wet dust collector. Wet dust collector, also called washing dust collector, is a device that separates dust particles from the air stream through the contact and impact of dusty gas and liquid droplet or liquid film. Wet dust remover can not only purify the solid particulate pollutants in the exhaust gas, but also remove the gaseous pollutants (gas absorption), and also play the role of gas cooling. Wet dust collector also has the characteristics of less equipment investment, simple structure and high purification efficiency. The equipment itself generally has no movable parts, suitable for purifying all kinds of dust that is not fibrous, does not react with water, does not occur adhesion phenomenon, and is suitable for purifying high temperature, flammable, explosive and harmful gases.

According to the Venturi principle, it is designed to deal with high concentration of dust. In the upstream area of the Venturi pipe, washing water is injected, and the Venturi effect accelerates the air flow, and the water flow is decomposed into small water droplets. In the venturi pipe throat, the dusty waste gas and water droplets strongly interact, the pollutant particles and water droplets are fully mixed, and the washed waste gas and dust droplets enter the downstream centrifugal separation structure tangentially to achieve separation; The dust is discharged by the fan downstream of the clean gas side after the air flow is purified by the Venturi wet dust collector. In the washing water collection area, precipitation separates the pollutants; Bottom sediment can be centrally collected and cleaned in several ways.

Working principle of Venturi wet dust collector

The dust blower is used to draw the air containing dust into the air inlet of the wet dust removal system, and the Venturi principle and star unloader are used to preliminarily filter and separate the large dust particles and discharge them to the pre-discharge dust box of the system. The rest of the air containing fine particles into the formal water mist dust removal follow-up treatment, in the water mist and dust fully mixed, dusty sewage into the filter tank, through the precipitation to form silt, silt by scraping the mud system scraped out to the mud cart, sewage through the sewage treatment system purification after recycling.
