A water cyclone for waste gas purification

Abstract

The invention discloses a water cyclone for purifying waste gas, comprising a cylindrical water cyclone box and a purification chamber arranged in the water cyclone box. The key points of the technical scheme are that a plurality of air inlet holes for waste gas to enter are opened on the side wall of the purification chamber. After water is sprayed out through the water spray holes, it fully contacts with the waste gas and then mixes with organic matter in the waste gas. The waste gas and water mist move upward through a fan. A first motor drives a centrifugal disc to rotate. The water mist is adsorbed on the bottom surface of the centrifugal disc and moves toward the outer side surface of the centrifugal disc through centrifugal force. The water mist quickly converges through a guide body, which speeds up the convergence speed of the water mist, so that the water mist can be separated from the centrifugal disc more quickly, thereby speeding up the waste gas purification efficiency. The water mist is then thrown onto a water retaining disc and a water collecting disc and discharged from a water outlet. The two centrifugal discs enable the water mist that bypasses the lower centrifugal disc to be blocked on the upper centrifugal disc, thereby increasing the waste gas purification rate.

Description

Technical Field
