Three-phase separator

Abstract

The invention discloses a three-phase separator and belongs to the technical field of sewage treatment. The problems of poor separation effect and incomplete separation are solved. According to the technical key points, the three-phase separator comprises a box body, an exhaust assembly and a drainage assembly, the exhaust assembly comprises an exhaust pipe and gas collection hoods, the upper endsof the gas collection hoods are fixedly connected with sliding sleeves, the gas collection hoods are vertically and slidably connected with counterweight frames, the counterweight frames are fixedlyconnected with buoyancy blocks, gas transmission pipes are arranged between movable grooves and the exhaust pipe, upper gas holes and lower gas holes are formed in the sliding sleeves, ventilation pipes with the two ends communicating with the upper gas holes and the lower gas holes are mounted in the sliding sleeves, filter nets located at the lower gas holes are fixedly mounted in the sliding sleeves, scum openings located in the lower parts of the lower gas holes are formed in the sliding sleeves, storage boxes communicating with the scum openings are mounted in the sliding sleeves, and thegas transmission pipes are provided with opening and closing mechanisms connected with the counterweight frames. The effect of sewage separation is improved, the advantage of more thorough separationis achieved, and the treatment efficiency of an overall sewage treatment process is greatly improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a three-phase separator. Background technique [0002] In the process of sewage treatment, when impurities such as gas and solid are mixed in the liquid, it will affect the normal operation of the sewage purification equipment and the sewage treatment effect. A three-phase separator is a device capable of separating liquids, gases and solids. [0003] The Chinese invention patent with the notification number CN203021354U disclosed a three-phase separator on June 26, 2013. It is arranged at the upper end of the UASB reactor and includes a box without a bottom. In the middle of the box, there are two vertical Straight partition, the vertical partition divides the box into a left separation chamber, a right separation chamber and an air collection chamber between the left separation chamber and the right separation chamber, and several A gas collection hood with an invert...

AI Technical Summary

Problems solved by technology

In the process of sewage treatment, the sewage is flowing, so that when there is gas stored in the gas collecting hood, waves floating on the liquid surface of the sewage in the gas collecting hood are likely to generate waves due to the influence of the water flow, and the waves will remove impurities floating on the liquid surface. Pushing to the air inlet will easily affect the discharge of gas, and will also affect the separation of gas

Therefore, there are problems in the prior art that the separation effect is poor and the separation is not thorough enough.
