The upper edges of all the liquid baffle plates are flush.
The lower section of the liquid collecting plate is a root plate which is vertical and is fixedly connected (welded) with the bottom of the liquid collecting tank, the middle section of the liquid collecting plate is a guide arc plate, the lower edge of the liquid baffle plate is smoothly connected with the upper edge of the guide arc plate into a whole, and the lower edge of the guide arc plate is smoothly connected with the upper edge of the root plate into a whole;
and a gap is reserved between the side edge of the liquid collecting plate and the side wall of the liquid collecting groove.

The invention has reasonable design and ingenious conception, and has the following beneficial effects:
1) The gas-lifting liquid collector is characterized in that gas can pass through the liquid collector through an ingenious structural design, and liquid is blocked and cannot pass through the liquid collector, so that the liquid is collected and sent to the next procedure. This function is achieved by the liquid barrier being angled to cover the top of the outlet of the draft tube. Because the liquid is required to continue downwards, the only channel of the liquid is the gas lift pipe, when the upper part of the gas lift pipe is shielded, liquid drops from the upper part cannot fall into the gas lift pipe, and the liquid drops intercepted by the liquid baffle only can flow downwards along the guide arc plate and cannot flow into the gas lift pipe at all. For the gas, the space above the outlet of the draft tube and the space for the water droplets are good ascending channels, so the air is unobstructed.
2) The gas ascending channel of the gas ascending liquid collector is particularly smooth, and has no sharp bend and no turn-back, so that the resistance loss of gas ascending is very small, and the energy is saved.
3) The gas-raising pipes are almost uniformly distributed on the cross section of the tower shell, so that the working state in the tower is more uniform and consistent, and the efficiency is higher.
4) The side edge of the liquid collecting plate is spaced from the wall of the liquid collecting groove by a proper distance, so that a flow passage of the collected liquid is provided, and the liquid is convenient to collect.
