Slag-containing sewage recovery device

Abstract

The invention discloses a slag-containing sewage recovery device. The slag-containing sewage recovery device comprises a liquid-solid separator, a steam-water separation and dust removal assembly, a vacuum pump, a power assembly and a slag discharge assembly which are mounted on an engine base, wherein the liquid-solid separator is connected with an air inlet of the steam-water separation and dustremoval assembly through a first pipeline; a slag-containing sewage connecting pipe and a water outlet are arranged on the liquid-solid separator; the water outlet is connected with a sewage liftingpump; the steam-water separation and dust removal assembly comprises a shell, a steam-water separator and a filter cartridge dust remover, and the steam-water separator and the filter cartridge dust remover are arranged in the shell; the steam-water separation and dust removal assembly is connected with a second pipeline through an air outlet; a control assembly is arranged at one end of the engine base and is connected with a first liquid level meter, a second liquid level meter, a third liquid level meter, a drainage electromagnetic valve and the power assembly. The slag-containing sewage recovery device provided by the invention is simple and reasonable in structure, and has the functions of recovering sewage, separating slag-containing sewage and conveying slag, so the application range of the device is wider.

Description

technical field [0001] The invention relates to the technical field of slag-containing sewage recovery, in particular to a slag-containing sewage recovery device. Background technique [0002] The treatment effect of slag-containing sewage in the prior art is unsatisfactory. For example, the sewage produced by high-pressure water derusting contains waste paint skin. If the sewage with waste paint skin is directly discharged into the sewage pool, in the existing In the sewage treatment equipment, the sewage containing slag cannot be treated, even if it is forcibly treated, it will cause some degree of damage to the sewage treatment equipment. [0003] Therefore, how to provide a device that can not only absorb particulate matter but also be used to recover slag-containing sewage for separation and transportation is a technical problem that urgently needs to be solved by those skilled in the art. Contents of the invention [0004] The invention provides a slag-containing se...
