The invention relates to an airlift pump system for conveying solid particles in underwater mining. The airlift pump system comprises a material collecting system, a lifting system, a pneumatic regulation and control system, a recycling system and the like. The material collecting system collects solid particles and guides the solid particles to a lifting opening of the lifting system, the material collecting system comprises a material containing hopper, a material guiding groove, a material collecting table and the like, the lifting system lifts and separates the solid particles and a liquid mixture, and the lifting system comprises an inclined hole air lift pump and a lifting pipe; the pneumatic regulation and control system comprises an electromagnetic valve, a plurality of auxiliary gas injection chambers, an optical fiber strain sensor, a microwave concentration sensor and the like. The recovery system comprises a gas-liquid separator, an axial flow turbine generator, an energy storage device, a stock bin and the like. Pipeline vibration and ore pulp concentration are monitored in real time through the optical fiber strain sensor and the concentration sensor, a PLC control algorithm is combined, the conventional operation mode, the vibration suppression operation mode and the anti-blocking operation mode are automatically switched, and the safety and stability of the airlift pump are greatly improved. The micro axial flow turbine generator is additionally arranged at the exhaust end, and tail gas kinetic energy is converted into electric energy.

This document describes a gas streaming device for use between an injection port and a mixing chamber within an airlift pump, and an airlift pump with the gas streaming device. The gas streaming device includes a planar plate with multiple holes extending therethrough, where the holes are dimensioned to direct the gas into multiple micro-streams for streaming air from the injection port into the mixing chamber. An airlift pump in combination with such a gas streaming device is useful for removing anomalously high concentrations of dissolved gas in a liquid. The increased efficiency for this invention may also enable this type of pump to be economic in other applications where it is desirable to lift a liquid or induce flow.
