High-efficient gas-water mixing device

Technical field:

the utility model relates to the technical field of sewage treatment, in particular to a high-efficiency gas-water mixing device.

The background technology is as follows:

conventional sewage treatment is mainly divided into three major parts: pretreatment, biological treatment and advanced treatment, wherein the biological treatment is the most important treatment unit, the biological treatment unit is divided into anaerobic treatment, anoxic treatment and aerobic treatment, the aerobic zone is mainly aeration and oxygenation to sewage, whether aeration in the aerobic zone is uniform and whether air-water mixing is sufficient or not are two factors influencing the treatment in the aerobic zone, the aeration mode adopted in the aerobic zone at present comprises microporous aeration, jet aeration, rotational flow aeration and the like, air is sprayed from the bottom of a reaction tank, an aeration disc or an aeration pipe is often blocked, the aeration method belongs to a static aeration method, and the air-water mixing cannot achieve the optimal effect.

The utility model comprises the following steps:

in order to solve the problem of poor aeration effect in sewage treatment, the utility model provides a high-efficiency gas-water mixing device.

The technical scheme of the utility model is as follows: the utility model provides a high-efficient gas-water mixing arrangement, including the reaction bucket, the welding of reaction bucket upper portion has the upper cover, the upper cover passes through bolted connection flange, flange hole welded connection intake pipe, the intake pipe lower part passes through built-in mechanical seal and connects the aeration pipe, built-in mechanical seal's rotating ring is installed in the hole of aeration pipe, built-in mechanical seal's quiet ring is installed in the hole of intake pipe, the aeration pipe is connected through bearing, retaining ring and spacer, it has the aeration hole of equipartition to open on the pipe wall of aeration pipe, the aeration pipe extends to the reaction bucket bottom, be equipped with inlet opening and apopore on the reaction bucket.

The aeration holes are processed along the tangential direction of the aeration pipe, and all the aeration holes are consistent along the tangential direction of the aeration pipe.

The water inlet hole is positioned at the center of the bottom of the reaction barrel, the water outlet hole is positioned at the upper part of the reaction barrel, the aeration pipe and the air inlet pipe are positioned at the center of the reaction barrel, and the conical water diversion cover is welded at the bottom of the aeration pipe.

The utility model has the following beneficial effects: compressed air enters the rotary sealing aeration pipe, the compressed air is sprayed out through the aeration holes, the aeration pipe rotates under the action of the tangential aeration holes, the rotary sprayed compressed air is efficiently mixed with sewage in the reaction barrel, the aeration pipe is rotated by utilizing the compressed air as power, the dynamic aeration is realized, the air-water mixing effect is improved, the sewage flows in from the bottom of the reaction barrel, flows out from the upper part of the reaction barrel after being fully mixed with the rotating air flow through the rising stage, and the impurities in the sewage are downwards precipitated and are not easy to be blocked when the machine is stopped due to the fact that the compressed air enters from the upper part of the reaction barrel, and the aeration holes are transversely arranged.

Description of the drawings:

FIG. 1 is a schematic diagram of the structure of the present utility model;

FIG. 2 is a section A-A of FIG. 1.

In the figure, the reaction barrel is 1-, the air inlet pipe is 2-, the air aeration pipe is 3-, the air aeration hole is 4-, the mechanical seal is 5-internally arranged, the dynamic ring is 51-, the static ring is 52-, the flange is 6-, the upper cover is 7-, the water outlet hole is 8-, the water inlet hole is 9-and the water distribution cover is 10-.
