Air floating head of dissolved air releaser

Abstract

The invention relates to the technical field of sewage treatment, and discloses an air floating head of a dissolved air releaser. The air floating head comprises a rotating shaft, wherein the bottom end of the rotating shaft is fixedly provided with a central disc, the outer end of the central disc is fixedly provided with a release pipe, the release pipe is hollow, the release pipe is a cylinder, a partition plate is fixedly installed at the vertical center line of an inner cavity of the release pipe and divides the interior of the release pipe into a tail end release cavity and a side edge release cavity. The length of the release pipe is increased, the radial range of the release pipe is expanded, then the interior of the release pipe is divided into the tail end release cavity and the side edge release cavity by the partition plate, the tail end release cavity and the side edge release cavity correspond to release holes in the tail end and the side edge of the release pipe respectively, it is guaranteed that the release pipe can make contact with dissolved gas in the radial range, formation of a dissolved gas blind area is avoided, and dissolved air release fan blades are arranged in an up-and-down staggered manner at the same time, so that the side dissolved air release airflow range is ensured, the circumferential range of the release pipe is expanded, and the air dissolving capacity of the floating air head is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an air floating head of a dissolved air releaser. Background technique [0002] Air flotation treatment of wastewater is also called flotation method. It uses highly dispersed tiny air bubbles as a carrier to adhere to pollutants in wastewater, making its buoyancy greater than gravity and buoyancy resistance. Under the action of air bubble carriers, pollutants will eventually Floating on the surface of the treatment tank, use the slag scraping equipment to scrape off the foam, and finally achieve the effect of solid-liquid separation. In this process, the dissolved air releaser is an important structure, and the pressure dissolved air can only be reduced through the dissolved air releaser. , to release a large number of fine air bubbles, affecting the final effect of air flotation water purification. [0003] Most of the existing dissolved air releasers release gas at t...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing air floatation head of the dissolved air releaser proposed in the background technology, the present invention provides an air floatation head of the dissolved air releaser, which can increase the contact area of ​​dissolved air and reduce the pressure difference resistance , the advantage of reducing the damage to the rotating shaft, which solves the problems raised in the above-mentioned background technology
