[0005] An aeration device is composed of a flow guide pipe and an air inlet pipe. The flow guide pipe is a hollow and vertically arranged straight pipe, the upper end of the flow guide pipe is open to form a pipe top opening, and the lower end of the flow guide pipe is open to form a pipe bottom opening. The air inlet pipe is composed of an air inlet section, a communication section and an aeration section. The air inlet section is in communication with the communication section, and the included angle between the two is a right angle. The aeration section is in communication with the communication section, and the included angle between the two is a right angle. The communication section penetrates the pipe wall of the flow guide pipe and makes the aeration section arranged inside the flow guide pipe. The end of the aeration pipe is a gas jet opening. The gas jet opening is arranged above the communication section.

[0006] The communication section is sealingly connected with the pipe wall of the flow guide pipe. The connection mode of the sealing connection is welding.

[0007] The distance between the gas jet opening and the pipe top opening is 1 / 4 to 1 / 3 of the total length of the flow guide pipe.

[0008] The air inlet pipe is at least one. When there are multiple air inlet pipes, each air inlet pipe can be in communication with an aeration device respectively, or can be in common communication with the same aeration device. The aeration device is an aeration fan.

[0009] The aeration device with the above structure is suspended in the water body during installation.

[0010] The pipe wall of the bottom of the flow guide pipe is further provided with water suction holes, which are arranged symmetrically and penetrate the pipe wall above the bottom opening of the flow guide pipe. The distance between the center of the water suction hole and the bottom opening is 0.5-2 cm. The aeration device with the structure can support the bottom of the flow guide pipe to the bottom of the pool during installation, so that the water inlet of the bottom opening is blocked, and the water can enter through the water suction hole. Preferably, the water suction hole is a gap arranged on the lower end of the flow guide pipe, which can be any one of rectangular, triangular, semicircular, semi-elliptical and rhombic.

[0011] The top opening of the pipe is further connected with a guide elbow. The aeration device with the structure can change the direction of the water outlet in the flow guide pipe through the guide elbow, so that the plug flow aeration can be realized.

[0012] Compared with the prior art, the aeration device has the following beneficial effects:

[0013] 1. Since the flow guide pipe is arranged, the aeration of the pool is changed from the traditional high-pressure aeration at the bottom of the pool to low-pressure aeration at the top of the pool, so that the energy consumption is greatly reduced, and a low-pressure and high-flow fan can be used for aeration, so that the aeration energy consumption is reduced.

[0014] 2. Compared with the traditional aeration pipe aeration, the aeration device has larger air volume and stronger water stirring intensity under the condition of using the same aeration fan, so that the water and air contact process is strengthened, and the effects of aerobic reaction and biochemical reaction are improved.

[0015] 3. By arranging the guide elbow, the air outlet direction of the flow guide pipe of the aeration device is parallel to the water surface, so that the plug flow effect is formed, and the aeration effect is improved.

[0016] 4. The aeration device has the advantages of low failure rate of the air outlet, and low production and processing cost. BRIEF DESCRIPTION OF DRAWINGS
