Long-distance small-slope-angle air disturbance and air lift simulation test device

The utility model relates to a long-distance small-slope-angle air disturbance and air lift simulation test device which comprises a test cylinder, a liquid lifting pipe, a communicating pipe, a test box and an air supply device. Two ends of the riser tube are transverse sections, and the middle of the riser tube is a vertical section; an outlet of a transverse section at the upper end of the riser tube extends into the test cylinder through the top of the test cylinder; an inlet of a transverse section at the lower end of the riser tube is communicated with an outlet of an upper connector of the test box after inclining by a certain gradient; an outlet in the bottom of the test cylinder is communicated with an inner cavity of the test box through a communicating pipe; an air lift outlet of an air disturbance and air lift test assembly in the test box is communicated with an inlet of the connector, and the air supply device supplies air to the air disturbance and air lift test assembly. The device has the ben
