Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection engineering, in particular to a lifting aeration device. Background Art

[0002] In the wastewater and waste gas treatment systems in the field of environmental protection, the mixing of liquid and gas is a common measure. For example: introducing the coal-fired flue gas emitted from the chimney into the alkaline absorption liquid, using the alkaline liquid to absorb the sulfur dioxide in the coal-fired flue gas and then purify it for emission; forcing the factory's discharged sewage to aerate, introducing oxygen in the air into the sewage, replenishing the dissolved oxygen required in the sewage purification process, etc. The most common aeration device is made of rigid materials in the shape of a tube or a nozzle, with holes evenly distributed on its working surface, and the gas is evenly distributed in the liquid through these dense small holes to achieve the purpose of introducing gas into the liquid.

[0003] In order to improve the efficiency of the aeration device, people have further developed an aeration device with an aeration membrane tube with aeration micropores. Its aeration element is a flexible material with a certain elasticity (such as flexible TPU, rubber tube) with high-density micropores evenly arranged. Aeration is carried out through these aeration micropores. When the pressure inside the flexible aeration membrane tube is lower than the external liquid pressure, the aeration micropores of the aeration membrane tube are closed, and the path for the liquid to flow back into the aeration membrane tube is blocked; when the internal pressure of the aeration membrane tube exceeds the external liquid pressure of the membrane tube, the flexible substrate is deformed to open the micropores, and the gas smoothly passes through the aeration micropores into the liquid for aeration.

[0004] At present, the vast majority of sewage treatment plants require that the aerator components be fixedly installed horizontally at the bottom of the biochemical pool from design to installation and construction. Although the oxygen supply effect is good, it brings inconvenience to maintenance and repair. Due to the complex composition of sewage and the large number of toxic and harmful substances, the corrosion of sewage treatment facilities is very harmful. The diaphragm is a fragile and consumable item. It is easy to tear, clog, and fall off when working in sewage for a long time, which affects the effect of sewage treatment and causes great trouble to the management and operation of sewage treatment plants. There is no better way to repair the aerator components. Only after stopping the operation and emptying the mixed liquid in the biological treatment pool can it be replaced and repaired, which will cause great harm to the surrounding environment. The government does not allow drainage to be stopped.

[0005] Therefore, it is necessary to set up a liftable aeration device, which can aerate the sewage at different positions of the pool body, and can be lifted to a designated position for maintenance when the aeration device is damaged. Utility Model Content
