Bubble curtain sewerage system and bubble curtain generation pipe

Abstract

The invention relates to a bubble curtain sewerage system and a bubble curtain generation pipe. A pipe body of the bubble curtain generation pipe is provided with a plurality of exhaust holes at intervals in the own axis direction, the openings of the exhaust holes face the water surface, one end of the bubble curtain generation pipe is an air inlet end, the other end of the bubble curtain generation pipe is sealed, the air inlet end is used for accessing high-pressure gas, and the spacing between adjacent two exhaust holes decreases from the air inlet end to the other end. The spacing betweenadjacent two exhaust holes decreases from the air inlet end to the other end to improve the uniformity of the flow at the outlets of the exhaust holes, so that the gas flow velocity at each exhaust hole is approximately the same, so that a generated bubble curtain forms a uniform diaphragm to strengthen the disturbance of fluid in the flow direction, strengthen the exchange process of the fluid quality and energy, and the blocking effect is improved.

Description

technical field [0001] The invention relates to the technical field of dredging sewage, in particular to a bubble curtain sewage drainage system and a bubble curtain generating pipe thereof. Background technique [0002] The traditional dredging construction will cause the suspended matter deposited in the surrounding waters to spread in the water or even float on the water surface, causing great pollution to the environment. In response to national laws and regulations on ecological and environmental protection, it is imminent to improve the serious pollution of dredging. The bubble curtain pipeline can have a certain barrier effect on the diffusion of suspended solids around during the dredging operation. It not only allows ships and equipment to move freely on the bubble curtain, but also blocks suspended substances. In the case of large dredging construction areas, long-distance pipelines will consume huge pressure, and the pressure and outlet flow at the end of the exi...

AI Technical Summary

Problems solved by technology

In the case of large dredging construction areas, long-distance pipelines will consume huge pressure, and the pressure and outlet flow at the end of the existing air bubble curtain pipelines are very small, which not only has no barrier effect, but even has a negative effect, making In the water area, the suspended matter on the bottom of the water is more turbulent, and it consumes a lot of energy
