A mud-water pulse mixing device

Abstract

A mud-water pulse mixing device, comprising an air supply device, a gas-collecting hood, a gas-liquid riser and at least one U-shaped air outlet pipe, the gas-collecting hood is connected with the gas-liquid riser so that the outer wall of the gas-liquid riser is connected to the gas-liquid riser An air-collecting chamber is formed between the inner walls, and the air-collecting chamber is connected with the gas supply device; the U-shaped air outlet pipe is provided with an air inlet and an air discharge port, and the U-shaped air outlet pipe communicates with the gas-liquid riser through the air release port, and the air inlet is close to At the top of the inner wall of the gas collecting hood, the level of the air outlet is greater than the level of the air inlet. The invention uses the gas collecting hood to collect gas, and then deflates the gas through the U-shaped gas outlet pipe, forming a powerful gas-liquid lifting effect in the gas-liquid lifting tube, realizing high-intensity, high-efficiency mixing; driven by a blower, low energy consumption and low operating costs Low; the unique U-shaped outlet pipe design makes the air collection volume controllable, and by controlling the air intake volume, the pulse mixing frequency can be controlled; the entire mixing device is under the liquid without any moving parts, no maintenance, and less failure.

Description

technical field [0001] The invention relates to the technical field of sewage treatment devices, and more specifically, to a mud-water pulse mixing device. Background technique [0002] In the sewage treatment system, the mechanical agitator is a commonly used mixing device at present. Although the mixing efficiency is high, each agitator needs to be equipped with a separate motor, which has the disadvantages of high energy consumption, large maintenance and easy failure. In addition, A special controller is required to adjust the stirring speed, and the equipment cost is high. Compared with mechanical agitators, coarse-hole aeration and air lift pumps have the advantages of less mixing maintenance and less failure, but their mixing efficiency is not high, and a large amount of oxygen will enter the water. If they are used for agitation in anoxic areas, It will also affect the denitrification effect. Contents of the invention [0003] In order to overcome at least one of...
