Description

A kind of aeration device used in organic water pollution degradation system

technical field

The invention relates to an aeration device, which is suitable for the technical field of organic water pollution degradation.

Background technique

Most of the aeration devices are used in sewage treatment systems, which can not only oxygenate the liquid through contact, but also agitate the liquid to increase the transfer speed of oxygen to the liquid, thereby completing the purpose of oxygenation. The traditional aeration device has the following shortcomings: some equipment is bulky, expensive, and difficult to disassemble and maintain, while the effective contact area of small aeration equipment is limited, which makes it difficult to ensure aeration efficiency.

The utility model patent with the application number of 201520496349.9 provides a spiral aeration device. The gas generated by the aeration device is transmitted to the inner rod of the support through the aeration pipe, reaches the aeration cavity of the support rod through the aeration holes of the inner rod of the surface of the support inner rod, and then reaches the spiral aeration cavity that communicates with it. Aeration is carried out through the aeration holes. This device is generally used in static aeration tanks with a large aeration area. However, in the flow environment, especially in the medium and high-speed flow environment, the support rod is under great stress, which is easy to cause damage to the equipment. Compared with the invention, the worm structure inside the worm barrel is integrated with the barrel wall, and the equipment is more stable, and the equipment is directly connected to the sewage treatment system without using the aeration tank, and the equipment is flexible and easy to maintain.

The invention patent with the application number of 201010208723.2 discloses an aerator. The kinetic energy of the motor located on the water surface is transmitted to the impeller located underwater through the motor shaft and the angular umbrella transmission joint. The high-speed rotation of the impeller makes the aeration chamber generate negative pressure. On the one hand, the pool water is sucked into the aeration chamber from the gap behind the impeller. On the other hand, the air is sucked into the air collection chamber by the air intake pipe, and the air entering the air collection chamber is broken by shock waves and the holes in the aeration chamber wall, and the broken air enters the aeration chamber from all angles of the aeration chamber wall. The air cavity is dissolved in water, and finally the water body mixed with sufficient oxygen is ejected through the guide tube at the front end of the aeration cavity under the pushing action of the impeller, and is fully mixed with the pool water. The invention is also a device placed in the aeration tank. The function area of the porous crushing plate is the inner ring wall, the aeration area is limited, and a certain buffer time is required according to the overall volume of the aeration tank. The flexibility is low, and the device Half is underwater and not easy to repair. Compared with the present invention, the device is directly connected to the sewage treatment system without using the aeration tank, the equipment is flexible and easy to maintain, and the worm structure inside the worm barrel can greatly increase the aeration area and improve the aeration efficiency.
