Bubble curtain sewerage system and bubble curtain generation pipe
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.
本发明涉及一种气泡帘排污系统及其气泡帘发生管，气泡帘发生管的管体沿其自身轴线方向间隔布置有多个排气孔，排气孔的开口朝向水面，气泡帘发生管的一端为进气端，另一端密封设置，进气端用于接入高压气体，相邻两个排气孔之间的间距由进气端向另一端依次变小。相邻两个排气孔之间的间距由进气端向另一端依次变小，提高排气孔出口流量的均匀性，使各个排气孔处的气体流速大致相同，使产生的气泡帘形成一道均匀隔膜，在流动方向上加强流体的扰动，强化流体质量和能量的交换过程，提高阻隔效果。
