And the gas sucked by the diversion pipeline is conveyed to the diversion pipeline again along the second pipeline or the third pipeline to the first well body and from the first well body to the water inlet pipe in sequence to form gas circulation.
The gas sucked by the second section of water flow in the first well body sequentially flows to the second well body along the first well body and the water outlet pipe, and is conveyed to the first well body through the horizontal pipeline, so that air circulation is formed, the pressure difference inside and outside the air inlet pipe is balanced, and the gas quantity sucked by the first well body is further reduced.
When the water inlet volume of coming water is big, a part rivers form the full flow in the reposition of redundant personnel pipeline, and no air gets into the space in the full flow pipeline, has reduced the air and has smugglied secretly, and another part directly flows into first well body from the inlet tube, and the process of the rivers breakage and the decomposition of this moment at first well body reduces, and the air entrainment volume reduces. And because of the entrainment of the air flow flowing to the water outlet pipe, the pressure intensity of the water outlet pipe is larger at the moment, the air flow flows to the second well body from the water outlet pipe, the second well body supplies air to the first well body through the horizontal pipeline, closed gas circulation is formed, the circulating air flow in the internal circulating air flow system is improved, the balance of the pressure difference inside and outside the air inlet pipe is facilitated, and the air volume entrained by the first well body is further reduced.
