Micro-power flotation separation equipment

Abstract

The invention relates to the technical field of sewage treatment, in particular to micro-power flotation separation equipment, wherein micro-power gas-liquid mixing is achieved by utilizing a Venturi principle, a large amount of micro-bubbles are generated through efficient jet injection, an oil liquid is aerated into floating oil foam floating on the upper layer of a mixed turbid liquid, the mixed turbid liquid is blocked by a box body high partition plate and a U-shaped oil collecting tank to form loopback flow in a circulating treatment process of the mixed turbid liquid so as to increase the air flotation treatment time of the mixed turbid liquid and improve the air flotation efficiency, and a slag collecting hopper at the bottom of the box body can rapidly precipitate slag and mud and discharge the slag and mud out of a box body through a bottom slag discharging opening so as to facilitate slag and sludge separation. The equipment comprises a supporting base, a box body, a mixed turbid liquid injection port, a U-shaped oil collecting tank, a box body low partition plate, a bottom slag collecting hopper, an oil collecting manifold, a box body high partition plate, a slag mud diaphragm pump, an oil liquid diaphragm pump, a slag mud vibration motor, a clear water centrifugal pump, a circulating water centrifugal pump, a circulating manifold, a Venturi tube, an efficient jet ejector, a ventilation port and a clear water injection port, wherein an inner cavity is formed in the box body.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a micro-dynamic flotation separation device. Background technique [0002] In the process of efficient evaporation treatment of organic matter, it is necessary to spray and purify the high-temperature volatile gas produced, and the mixed suspension of oil, water and slag produced after spraying is separated by micro-dynamic flotation separation equipment. The auxiliary device has been widely used in the field of sewage treatment technology; the existing flotation separation equipment has a relatively complicated structure, and the separation quality is average and the efficiency is low. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a microdynamic flotation separation device which can effectively separate the mixed suspension of oil, water and slag with good separation effect. [0004] A micr...
