Multifunctional gas-oil mixing and separating apparatus

Abstract

The invention discloses multifunctional gas-oil mixing and separating apparatus. The apparatus comprises a cylindrical tank body; an upper dirt discharging port is formed at the top end of the cylindrical tank body, and a dirt discharging fan and an activated carbon filtering layer are arranged in the upper dirt discharging port; a gas floating chamber is arranged in the cylindrical tank body; theair floatation chamber is provided with a first filter screen, an oil-water separation extraction opening, an oil-water separation device, a water inlet, a water outlet device, a water circulation device and a precipitation and pollution discharge device from top to bottom; the oil-water separation device comprises an oil-water separator and an oil pump; and the oil-water separator is connected with the oil pump and the oil-water separation extraction opening through pipelines. The sewage treatment efficiency of the apparatus provided by the invention is high, discharged gas is free of pollution, and gas-oil mixing and separating effects are good.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a multifunctional gas-oil mixing and separating device. Background technique [0002] The sewage treatment system can effectively treat urban domestic sewage, industrial wastewater, etc., and prevent sewage and pollutants from flowing directly into the water, which is of great significance to improving the ecological environment, improving the quality of the city and promoting economic development. For the removal of suspended solids, grease and other sundries in various industrial wastewater and domestic sewage, if the traditional sedimentation method is used, the oil-water separation effect is not good; while the air flotation method relies on the formation of tiny bubbles in the water, carrying the flocs to float to the liquid A method of purifying water. The condition is that the air bubbles attached to the oil droplets can form oil and gas particles. Since the appe...

Problems solved by technology

That is, when a bubble (or multiple bubbles) is attached to an oil droplet, the vertical rising speed can be increased, so that oil droplets with a diameter much smaller than 50 μm can be removed; while the current industrial production sewage and domestic sewage use sewage treatment After the equipment is treated, most of the gas generated by the sewage is directly discharged, and the discharged gas often has a pungent smell or other unpleasant smells, which seriously affects the working status of the sewage treatment workers and also pollutes the surrounding environment. environment, reducing the air quality and failing to meet the requirements of environmental protection
