Oily sewage microwave treatment device with sludge settling prevention function

Abstract

The invention relates to an oily sewage microwave treatment device with a sludge settling prevention function. The oily sewage microwave treatment device is provided with a sludge inlet, a slag outlet and a water outlet, wherein microwave tubes are arranged in the microwave treatment device; two rotary shafts are vertically arranged in the microwave treatment device, and comprise a first rotary shaft and a second rotary shaft in parallel; the lower end of the first rotary shaft is connected with a first motor at the bottom part of the microwave treatment device, and the upper end of the second rotary shaft is connected with a second motor at the top part of the microwave treatment device; a plurality of first rotary discs are arranged on the first rotary shaft at intervals, a plurality of second rotary discs are arranged on the second rotary shaft at intervals and are respectively parallel with the first rotary discs, and the first rotary discs are staggered with the second rotary discs; the microwave tubes are arranged at the upper and lower surfaces of the first rotary discs and second rotary discs, and the side surfaces of the first rotary shaft and the second rotary shaft; the first rotary shaft and the second rotary shaft respectively adopt a temperature-rise hollow shaft of which the side wall is provided with air exhaust holes, and the first rotary shaft and the second rotary shaft are respectively connected with a fan.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to treatment equipment for oily sewage. Background technique [0002] Oily sewage and sludge are generally stable suspoemulsion systems composed of oil-in-water (o / w), water-in-oil (w / o) and suspended solids, and most of the pollutants are refractory to biodegradable substances, so their Disposal has always been a difficult problem in the water treatment industry. The use of microwave catalytic treatment of domestic sewage has been applied in engineering, but the technology is not yet mature; the use of microwave technology in industrial wastewater treatment is still in the laboratory research stage, and the use of microwave technology in the treatment of oily sludge has not been reported. In addition, in the existing microwave water treatment equipment, there is a lack of properly arranged microwave tubes in the microwave reactor, and the overall microwa...

AI Technical Summary

Problems solved by technology

The use of microwave catalytic treatment of domestic sewage has been applied in engineering, but the technology is not yet mature; the use of microwave technology in industrial wastewater treatment is still in the laboratory research stage, and the use of microwave technology in the treatment of oily sludge has not been reported.

In addition, in the existing microwave water treatment equipment, there is a lack of properly arranged microwave tubes in the microwave reactor, and the overall microwave treatment method is adopted. The disadvantages are that the treatment is not thorough, the treatment time is long, and the efficiency is low; and the existing microwave treatment In the container, due to the bottom mud feeding method, the sludge is easy to accumulate at the bottom, resulting in poor dispersion effect, which is not conducive to the removal of oil stains
