Pressure bearing type purification device

Abstract

The invention provides a pressure bearing type purification device, which comprises a water inlet pipe, a sludge reflux area, a mixing agglomeration area, a flocculation reaction area, a sediment clarification area, a clear water gathering area and a water outlet pipe which are squencially communicated, wherein inclined plate filler is arranged in the sediment clarification area and is provided with an inclined plate sediment channel which is aslant arranged; the lower end of the inclined plate sediment channel is communicated with the lower part of the sediment clarification area; the upper end of the inclined plate sediment channel is communicated with the clear water gathering area; the bottom of the sediment clarification area is provided with a sludge area; the lower end of the inclined plate sediment channel is positioned above the sludge area; the sludge area is communicated with the sludge reflux area through a sludge reflux device; the bottom of the sludge area is provided with a blow-off pipe; the sludge reflux area, the mixing agglomeration area, the flocculation reaction area, the sediment clarification area and the clear water gathering area are all of a sealed structure. According to the pressure bearing type purification device, the technical problem in the prior art that sludge can not be smoothly discharged is solved.

Description

technical field [0001] The invention relates to the technical field of water treatment equipment, in particular to a pressure-bearing purification device. Background technique [0002] The inclined plate sedimentation tank, chemical degreaser integrated water purifier and rare earth disk and other equipment used in the industrial circulating water treatment system are all open atmospheric pressure equipment. The pressure enters the downstream processing equipment, resulting in larger system footprint, complicated operation, high investment, increased operation and management costs, and increased energy consumption; Not smooth, affecting the normal operation of the equipment; In addition, the above-mentioned equipment has unsatisfactory treatment effects, the content of suspended solids or oil content in the effluent is not up to the standard, or even the content of both is not up to the standard, which increases the processing load of subsequent equipment. The existing equi...

AI Technical Summary

Problems solved by technology

[0004] 1. Large area, complex operation, high investment, high operation and management costs, and high energy consumption;

[0005] 2. When discharging mud under normal pressure, there is a problem that the mud discharging pipe is blocked and the mud is not discharged smoothly;

[0006] 3. The water outlet effect is not ideal, the content of suspended solids or / and oil content in the effluent is not up to standard, and the processing load of subsequent equipment is increased;

[0007] 4. There is no sludge return design, or a mud pump is used as the sludge return equipment, which has poor adaptability to the influent water quality, increases power consumption, and has a high failure rate
