Embodiment Construction

[0032] see Figure 1-3 Shown the first embodiment, this embodiment is the situation that the water dividing plate is perpendicular to the horizontal plane and the sludge is discharged straightly (clean water side discharge).

[0033] In this embodiment, the precipitator mainly includes a housing 4, a water inlet pipe 1 on the housing 4, a clear water outlet pipe 16, a mud discharge pipe 19, an exhaust pipe 20, and a flocculation reaction chamber 11 connected to the water inlet pipe 1. The outlet is connected to the water distribution device 2 , and the flocculation reaction chamber 11 and the water distribution device 2 are located on the upper partition 3 . A group of sloping plate settling devices 22 composed of sloping guide parts 5 are arranged between the upper partition 3 and the lower baffle 17 in the housing 4. The sloping guide parts 5 can be inclined plates or tubes, hereinafter collectively referred to as sloping plates. Each sloping plate 5 has a water inlet and a...

Abstract

The precipitator has a casing, a water inlet pipe, a water outlet pipe, a mud draining pipe, a set of inclined guide parts, a set of collectors, which are in the drainage end of the guide parts. Each collector includes a water dividing board, a return board,and side boards to form a collecting space among them and channels formed between adjacent collectors are connected to the first collecting chamber in the lower part inside the casing. In the side boards, there are openings to the second collecting chamber on the side of the guide parts.

Description

technical field [0001] The invention relates to a precipitator, in particular to an inclined cocurrent flow precipitator. Background technique [0002] Existing precipitators include cocurrent flow precipitators and counterflow precipitators. In this kind of precipitators, the use of inclined guide components, that is, inclined tubes or inclined plates, can significantly improve the sedimentation efficiency of the sedimentation tank. The sedimentation efficiency of the co-flow inclined plate settler whose water flow direction is the same as that of the sludge flow is significantly higher than that of the counterflow inclined plate settler whose water flow direction is opposite to the sludge flow direction. CN86107912 discloses a cocurrent shallow inclined plate settler, which uses tubular water collection technology and secondary sludge diversion technology to solve the problems of turbulent flow and sludge accumulation in the sedimentation device when clarified water is sep...
