Arc-shaped gas-water separator

Abstract

The invention provides an arc-shaped gas-water separator which is characterized by comprising an arc-shaped plate, a plurality of reinforcing and supporting vertical ribs located in the inner side of the arc-shaped plate, a vertical baffle arranged at one end of the arc-shaped plate, a plurality of horizontal fixing bottom plates horizontally extending and lapped on the lower side of the arc-shaped plate, a lower fixing L-shaped folded plate welded to the bottom of the arc-shaped plate and the like. The gas-water separator is arranged between a sewage aeration tank and a secondary sedimentation tank, the outer side of the arc-shaped plate faces the aeration tank, the inner side of the arc-shaped plate faces a through-wall hole communicated with the aeration tank and the secondary sedimentation tank, and a flow channel formed by the arc-shaped plate and the through-wall hole is an equal-diameter flow channel. The gas-water separator is simple in structure, smooth, free of blockage and small in head loss, and compared with an existing gas-water separation device, the gas-water separator has the advantages of being energy-saving, free of faults, low in manufacturing cost, small in occupied area, good in gas-water separation effect and the like.

Description

technical field [0001] The invention belongs to the field of gas-water separation of sewage aeration biochemical treatment technology, and specifically relates to an arc-shaped aeration system that can realize rapid, convenient and smooth separation of air bubbles and activated sludge mixed liquid before the gas-liquid-solid three-phase mixed liquid enters the secondary settling tank. water separator. Background technique [0002] In the field of sewage biochemical treatment technology, when the aeration tank and the secondary settling tank are jointly built (shared pool wall), if the mixed liquid in the aeration tank directly enters the secondary settling tank, it will bring a bad problem-the mixed liquid The medium air bubbles enter the secondary settling tank with the water flow, which will disturb the sedimentation layer of activated sludge and seriously affect the effluent water quality of the secondary settling tank. In the past, in order to eliminate the air bubbles ...

AI Technical Summary

Problems solved by technology

However, in addition to occupying land, the traditional method also consumes two parts of the water head from the aeration tank to the air-water separation box / room and the air-water separation box / room to the secondary sedimentation tank, which makes the water head loss in the process larger, which is not conducive to energy saving operation, and because the surface of the aeration tank and the secondary sedimentation tank will inevitably have a large height difference, which is not conducive to the layout of the process flow and the integrated construction of civil engineering

[0003] my country's patent "Horizontal Slit Type Gas-Water Separator" (notification number CN 103395853 A, announcement date 2013.11.20), the equipment is composed of ascending deflector sloping plate, vertical stabilizing plate, oblique deflecting silt plate, etc. It is a variable channel overflow, and the upper inlet of the gas-liquid-solid three-phase mixture is narrow, and the middle overflow channel is also narrow, which affects the degree of guarantee of the gas-water separation effect, and there is only one row of fixing screws, which is resistant to lateral deformation The ability is not strong, and its positive stability is poor when the pool is filled with water, and it is easy to shake and cause loosening, and the structure of the equipment is slightly complicated, so it is not suitable for large-scale sewage treatment

In addition, due to the small hole height and insufficient space for the electric drill to operate the equipment during installation, it is difficult to drill vertically.

Therefore, the horizontal slit type air-water separator of this patent has relatively large limitation
