Rotary filler self-cleaning oil sludge slag-water separation tank

Abstract

The invention discloses a rotary filler self-cleaning oil sludge slag-water separation tank which comprises a flocculation reaction tank; the rotary filler self-cleaning oil sludge slag-water separation tank further comprises a separation tank body, a slag and sludge scraping machine located in the separation tank body, a rotary filler bracket capable of driving a rotary filler main body to rotate in the separation tank body, and a water outlet area fixing filler. Through the flocculation reaction tank, a central cylinder, a gas dissolving water pipe, the rotary filler main body, the water outlet area fixed filler and the slag and sludge scraping machine, the problem of low actual surface load is effectively solved, the water outlet quality is improved, more effective protection is provided for a subsequent treatment unit, and the rotary filler self-cleaning oil sludge slag-water separation tank is worthy of being vigorously popularized.

Description

technical field [0001] The invention relates to the technical field of oil sludge water separation, in particular to a rotary packing self-cleaning oil sludge water separation tank. Background technique [0002] At present, when the water treatment industry is dealing with oily sewage or water containing light pollutants with a density smaller than water and pollutants with a higher specific gravity than water, it adopts three rectangular pool distribution structures to treat this type of sewage, that is, the sewage is treated in turn. The oil-water separation, slag-water separation and mud-water separation are carried out in sequence for this type of sewage in the three types of pools introduced into the radial-flow grease trap, radial-flow air flotation tank, and radial-flow sedimentation tank. Usually, a fixed packing support is installed in the middle of the radial flow type grease trap for oil-water separation, and the oil-separating packing body is densely covered on t...

AI Technical Summary

Problems solved by technology

Usually, a fixed packing support is installed in the middle of the radial flow type grease trap for oil-water separation, and the oil-separating packing body is densely covered on the fixed packing support, and the oil-separating packing body is used for oil-water separation of the oily residue sewage, and the muddy sewage enters the radial flow type in turn. Slag-water separation and mud-water separation are carried out in air flotation tanks and radial flow sedimentation tanks. The sludge in the sludge-containing sewage after deslagging is removed by a mud scraper after sedimentation at the bottom of the sedimentation tank; there are the following deficiencies: (1) three rectangles The pool distribution structure has a large investment cost and a large area; (2) The oily sewage cannot enter the radial-flow grease trap evenly, nor can it pass through the oil-separating packing body densely distributed on the fixed packing support, so that the oil-separating packing body is partially blocked. There is also sludge accumulation at the bottom of the tank at the lower end of the oil-separating packing body. It is necessary to stop the sewage treatment frequently and remove the fixed packing bracket to clean the oil-separating packing body. It is time-consuming and labor-intensive to remove the accumulated sludge at the bottom of the pool at the lower end of the oil-separating packing body. Seriously affect the sewage treatment process; (3) In practical applications, due to the fact that the sewage contains oil or pollutants with a lower density than water cannot be intercepted, the quality of the effluent water deteriorates, which has a huge impact on the subsequent treatment units, especially when the subsequent When the treatment unit is a biological filter or an ozone catalytic oxidation unit, it may even cause serious consequences such as irreversible blockage of biological fillers or catalyst failure
