Problems solved by technology

The air dissolved in water is precipitated from the water in the form of tiny bubbles, and the suspended solid particles in the sewage are floated on the water surface and scraped out by the slag scraper to achieve solid-liquid separation. In order to capture the suspended solids at most, the suspended solids in the air floatation The air bubbles should be as small as possible and evenly distributed, the existing air dissolving tanks are not ideal for dissolving air

Abstract

The invention provides an air dissolving tank which has a rational structure and improves an air dissolving effect. The air dissolving tank comprises a tank body; the tank body has a hollow structure, two sides of the tank body are each provided with a flange, the upper end of one end of the tank body is provided with a water inlet, the lower end of the other end of the tank body is provide with a water outlet, and the flange of one end provided with the water inlet is provided with an air inlet. The air dissolving tank is characterized in that the air dissolving tank is internally provided with a rotating shaft passing through the flanges; the rotating shaft is connected with a driving device and is provided with an air dissolving fan; blades of the air dissolving fan are each provided with convexes; two sides of each convex are arranged in a penetration manner.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an air-dissolving tank. Background technique [0002] The dissolved air tank is an important equipment in the pressure dissolved air flotation purification process. The dissolved air tank is a device that pressurizes the clean water through the reflux pump and adds compressed air at the same time to dissolve the air in the water. The air dissolved in water is precipitated from the water in the form of tiny bubbles, and the suspended solid particles in the sewage are floated on the water surface and scraped out by the slag scraper to achieve solid-liquid separation. In order to capture the suspended solids at most, the suspended solids in the air floatation The air bubbles should be as small as possible and evenly distributed. The air-dissolving effect of existing air-dissolving tanks is not ideal. Contents of the invention [0003] In view of the above problems, the p...
