Combined-type electrofloatation device

Abstract

The invention relates to a combined-type electrofloatation device, which comprises a plurality of electrofloatation tanks using standardized box body; wherein, the electrofloatation tanks are in parallel to each other, the box body thereof is rectangle, and two ends thereof are provided with three identical connection short pipes with identical flanges, namely, an upper connection short pipe, a middle connection short pipe and a lower connection short pipe; the position close to an inlet in the box body is provided with an electrolytic gas-dissolved cavity subdivided by a wallboard of the electrolytic gas-dissolved cavity; an electrolytic electrode assembly is arranged in an electrolytic gas-dissolved chamber; the top part of the box body is provided with a cinder scraper; a conveying belt of the cinder scraper is provided with a skimming plate; one of the upper connection short pipes of the box body is a slag hole; an overflow weir matched with the cinder scraper with the cinder scraper is arranged in front of the slag hole; the lower connection short pipe mounted at the front end of the box body is an inlet, while the one mounted at the back end of the box body is an outlet. The invention has fine floatation effect, and can be assembled with treatment devices of other box bodies in the same specification at will to establish different treatment systems, thus being favor of reducing cost, simplifying installation and ensuring the treatment effect of sewage.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a combined electrolytic air flotation device, which belongs to the technical field of environmental protection. Background technique [0002] For small-scale sewage discharges that often occur in life or production, especially in places far away from municipal pipes, it is necessary to set up a small sewage treatment system for sewage treatment to make it meet the discharge standards for on-site discharge. This type of small-scale sewage Due to the small processing capacity of the treatment system, the investment that can be borne is not large. Therefore, a finished product with wide adaptability and relatively low cost is required to produce a unified finished product in the factory without independent design for various specific sewage properties. and engineering construction. In view of the fact that such pollutants usually exist in sewage: floating substances such as oil, sedime...

AI Technical Summary

Problems solved by technology

[0003] However, due to the different amounts of sewage discharged from different sewage sources, a single sewage treatment system cannot be adapted to the sewage treatment of various sewage discharge sources, and the pre-production of various sewage treatment systems with different specifications not only requires more cost in design and production Large, and the treatment process for different sewage may also be different, so the adaptability of the pre-designed and produced treatment equipment will be problematic
