Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a high-efficiency jet gas-liquid mixing device. Background Art

[0002] In the sewage treatment industry, aeration refers to the process of forcibly transferring oxygen from the air to the liquid. Its purpose is to increase the dissolved oxygen in the water. At the same time, aeration can effectively prevent the sinking of suspended matter in the pool and strengthen the contact effect between organic matter and microorganisms and dissolved oxygen in the pool, thereby ensuring that the microorganisms in the biological pool can oxidize and decompose organic matter in the sewage under the condition of sufficient dissolved oxygen. Jet aeration has the advantages of simple structure and low infrastructure investment, and is widely used in engineering. However, jet aeration has low sewage treatment efficiency in the sewage treatment process. It is urgent to design a jet gas-liquid mixing device that can treat sewage thoroughly, comprehensively and efficiently. Utility Model Content

The water outlet of the sewage submersible pump is connected to the sewage inlet of the gas-liquid mixing part through the delivery pipe, the air inlet of the gas-liquid mixing part is connected to the air outlet of the blower, the sewage outlet of the gas-liquid mixing part is connected to the annular pipe through the delivery pipe, and an injection head is installed on each side of the annular pipe.

[0004] The gas-liquid mixing part is composed of a liquid infusion tube, a baffle, a mixing chamber and an air inlet pipe. The liquid infusion tube runs through the mixing chamber, one side of the mixing chamber is connected to the air inlet pipe, and a baffle is arranged inside the diffusion section of the liquid infusion tube.

[0005] The infusion tube adopts a Venturi tube design.

[0006] The air outlet of the blower is connected to the air inlet pipe.

[0007] Both ends of the infusion tube are communicated with the delivery tube respectively.

[0008] Furthermore, the sewage submersible pump is installed in a sewage tank.

[0009] Furthermore, the annular pipe is installed at the bottom of the sewage pool in a surrounding arrangement structure.

[0010] Beneficial effects of the utility model:

[0011] The utility model arranges the pipeline for conveying the gas-liquid mixture to the sewage pool in a ring shape at the bottom of the sewage pool, and a spray head is arranged on each side of the ring pipeline to spray sewage aeration treatment, thereby expanding the coverage of sewage treatment, thereby improving the sewage treatment effect, and the treatment is more thorough and efficient;

[0012] The infusion pipe in the gas-liquid mixing part of the utility model adopts a venturi tube design. After the gas is inhaled, the gas and liquid are mixed in the mixing chamber, and the mixed gas and liquid are dispersed by the baffle plate of the diffusion section on the upper part of the infusion pipe, and more bubbles are generated in the water and transported to the sewage pool, so that the air and sewage are in contact more fully.

[0021] Example 1

[0022] As shown in the figure, the sewage submersible pump 1 is installed in the sewage pool 100. The water outlet of the sewage submersible pump 1 is connected to the sewage inlet 311 at the short cone end of the infusion pipe 31 through the delivery pipe 2. The infusion pipe 31 adopts a venturi tube design. When the venturi tube delivers high flow, the pressure loss is small, which can save energy costs during operation. The infusion pipe 31 passes through the mixing chamber 32. One side of the mixing chamber 32 is connected to the air inlet pipe 33. The air outlet of the blower 4 is connected to the air inlet pipe 33. A baffle 34 is arranged inside the diffusion section of the long cone end of the infusion pipe 31. The sewage outlet 312 of the infusion pipe 31 is connected to the annular pipe 5 through the delivery pipe 2.

The blower 4 delivers the gas into the mixing chamber 32 through the air inlet pipe 33, and mixes with the liquid and enters the long conical end of the liquid delivery pipe 31. The bubbles in the liquid are dispersed by the baffle 34, and then delivered to the sewage pool 100 through the delivery pipe 2, so that the air and sewage are in contact more fully, thereby increasing the aeration effect.

[0025] The annular pipe 5 is arranged in an annular shape at the bottom of the sewage pool 100, and a spray head 6 is provided on each side of the annular pipe to spray and aerate the sewage, thereby expanding the coverage of the sewage treatment, thereby improving the sewage treatment effect and making the treatment more thorough and efficient.
