Problems solved by technology

[0002] In the prior art, in agricultural production and environmental treatment technology, mechanical agitation is usually used to realize mass transfer or aeration method is used to realize oxygen and mass transfer, but usually the impeller or aeration device is directly placed in the water body. Oxygen transfer and mass transfer methods have low efficiency and small water surface, and some aeration methods require the laying of gas pipelines
Therefore, the cost of use is high, and it is difficult to implement in large areas of water

Embodiment Construction

[0010] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0011] Such as figure 1 As shown: it includes an air distributor 2 and a gas-liquid mixer 1 , and the air distributor 2 is arranged at the inner bottom of the gas-liquid mixer 1 . The air distributed by the air distributor 2 enters the gas-liquid mixer 1. The lower part of the gas-liquid mixer is a mixing zone where air and water are mixed. The middle part is a diversion zone to keep the gas-liquid mixture moving according to the direction. Oxygen water diffuses to the periphery, forming water circulation at the same time.

Abstract

The invention relates to a gas-liquid mixing-circulating device for microorganism cultivation in water bodies, and in particular belongs to the agriculture and environment technical field. The device comprises an air distributor and a gas-liquid mixer. The device is characterized in that: the inner bottom end of the gas-liquid mixer is provided with the air distributor; the gas-liquid mixer has a mixing area formed on the lower part, has a stream guiding area formed on the middle part and has a diffusion area formed on the upper part. The device is simple, compact and reasonable in structure, can be arranged in a complex water body, and can ensure that uniform air distributed by the air distributor and the water body are fully mixed in the gas-liquid mixer; a gas-liquid mixture after the uniform and the water body are mixed flows orderly; and an oxygen enriched water body and an oxygen-deficient water body are circulated mutually and diffused uniformly all around the water body, so as to realize the mass transfer and oxygen transfer of a large water body. The device has the advantages of high mass-oxygen transfer efficiency, convenient installation and simple maintenance.

Description

technical field [0001] The invention relates to a gas-liquid mixing circulation device for microbial cultivation in water bodies, specifically for oxygen transfer and mass transfer, which can promote the growth of beneficial aerobic microorganisms in water bodies and improve the water body environment, and belongs to agriculture and environmental technologies. Background technique [0002] In the prior art, in agricultural production and environmental treatment technology, mechanical agitation is usually used to realize mass transfer or aeration method is used to realize oxygen and mass transfer, but usually the impeller or aeration device is directly placed in the water body. Oxygen transfer and mass transfer methods have low efficiency and small water surface, and some aeration methods require the laying of gas pipelines. Therefore, the use cost is high, and it is also difficult to implement in a large area of ​​water. Contents of the invention [0003] The object of t...
