Problems solved by technology

[0003] In the existing air flotation device, the release pipeline is only controlled by a valve on the main pipeline, and the control effect on the release volume is not good in actual operation
In addition, the air flotation device in the prior art is open in the slag scraping section, and the gas released by the sewage and the liquid medicine has a strong pungent smell, causing secondary pollution to the surrounding environment, which does not conform to the modern concept of green environmental protection

Abstract

The invention discloses a gas floating device which comprises a coagulation reaction device, a contact chamber and a gas floating tank, wherein a dosing port, a water inlet hole, an exhaust hole, and a stirring machine which extends into the gas floating device are formed in the coagulation reaction device; a releaser, a dissolved gas water inlet hole and a compressed gas inlet hole are formed in the contact chamber; a slag scraping machine is arranged above the gas floating tank; a slagging hole, a water outlet hole and a return water outlet hole are formed at one side of the gas floating tank; the releaser is provided with valves; and a gas collecting cover is arranged above the gas floating tank. The releaser of the gas floating device is provided with a plurality of branch pipes which are respectively provided with the valve, so that the release quantity is effectively controlled; and the gas collecting cover is arranged above the gas floating tank, so that the poisonous and harmful gases can be collected, and the device is environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of environmental protection water treatment and purification equipment, and in particular relates to a dissolved air flotation device. Background technique [0002] The air flotation device is a device that uses the air flotation method for solid-liquid or liquid-liquid separation. The air flotation device absorbs fine impurities in the treated water to the air bubbles by introducing tiny air bubbles into the water, forming flocs and floating up with the air bubbles to form scum, which is then scraped off by the slag scraper to remove suspended impurities in the water. [0003] In the existing air flotation device, the release pipeline is only controlled by a valve on the main pipeline, and the control effect on the release amount is not good in actual operation. In addition, the air flotation device in the prior art is open at the slag scraping section, and the gas released by the sewage and liquid medicin...
