Mist microvesicle gas jet aeration head

Abstract

The invention relates to a fog shape micro-bubble gas jet current aerated head, which comprises a gas inlet structure, a gas outlet end sleeved at the gas inlet structure, and a gas outlet structure tightly combined with the gas inlet structure. The center of the gas inlet structure axially forms a gas inlet channel; a pressure balancing channel is axially formed between the inner wall and the outer wall of the gas inlet structure; the outer wall of the gas inlet structure extrudes outwards so as to form a balancing gas pipe which is communicated with the pressure balancing channel; the gas outlet end of the gas inlet structure forms an outer screw thread used for connecting the gas inlet pipe; the gas inlet channel is internally provided with a nozzle core. The center of the gas outlet structure axially forms a gas outlet channel; the joint of the front end of the gas outlet structure and the gas outlet end of the gas inlet structure is formed with a mixing chamber which is communicated with the gas outlet channel of the gas outlet structure; the mixing chamber is internally provided with a ball shape unilateral valve. The fog shape micro-bubble gas jet current aerated head of the invention can cause the water in the biological pool to produce fog shape micro bubble, can effectively improve the air utilization rate, the power efficiency and the mixing efficiency, reduce the power consumption of a draught fan, reduce the capacity of the draught fan, and reduce the cost.

Description

technical field [0001] The invention relates to an underwater under-expansion low-pressure low-speed gas jet device. In particular, it relates to a mist-like micro-bubble gas jet aeration head capable of generating a mist-like micro-bubble mixture in a water body and effectively improving air utilization rate, power efficiency and mixing efficiency. Background technique [0002] At present, there are two types of known biological pool aeration devices: the first type of gas bubbling type, including: (1) the microporous aerator whose working fluid channel is air, variable microporous aerator, microporous aerator Inflator; (2) The channel of the working fluid is also the basin-shaped aerator head, diffuse flow aerator head, and Jinshan aerator head of the air. The second type of jet aerator in which the channel of the working fluid is liquid includes: (1) self-priming underwater jet aerator; (2) air-supply underwater jet aerator. [0003] Wherein, the first category (1) is t...

AI Technical Summary

Problems solved by technology

The disadvantage is that the working fluid is easy to entrain the debris in the biological tank into the mixing chamber and block the channel

Its disadvantages are: the pressure of the working fluid is relatively high, and the conditions of use are limited
