Abstract

The invention discloses a gas-liquid mixer. The gas-liquid mixer comprises a straight pipe, wherein a retracting pipe is inserted into an inlet end of the straight pipe and an expanding pipe is inserted into an outlet end of the straight pipe; the outlet end of the retracting pipe and the inlet end of the expanding pipe are opposite, but are not in contact; the diameter of the outlet end of the retracting pipe is less than the diameter of the inlet end of the expanding pipe; a first through hole is formed in a corresponding part, located between the retracting pipe and the expanding pipe, on the straight pipe. The gas-liquid mixer provided by the invention is simple in structure and low in manufacturing cost; the gas-liquid mixer is easily connected with an upstream pipeline and a downstream pipe and is small in occupied area.

Description

technical field [0001] The invention relates to the technical field of mixing equipment, in particular to a gas-liquid mixer. Background technique [0002] The air flotation process is often used in wastewater treatment, mainly by introducing air into the wastewater, so that highly dispersed micro-bubbles are formed in the wastewater, and the particles in the wastewater adhere to the bubbles to form flocs with an apparent density lower than water and float to the water surface , for further separation. In order to realize the mixing of waste water and air, a mixing tank is mainly provided in the prior art, and then the waste water is passed into the mixing tank through a water pump, and the air is passed into the mixing tank through an air pump. However, the disadvantages of such an arrangement mainly include a large number of equipment, complicated piping, and a large footprint. [0003] It can be seen that the prior art still needs to be improved and enhanced. Contents...
