Micro-nano bubble generator with adjustable bubble particle size and adjusting method

Abstract

The invention discloses a micro-nano bubble generator with an adjustable bubble particle size and an adjusting method. The micro-nano bubble generator comprises a water supply pipeline, a gas supply pipeline, a mixer, a booster pump, a gas-liquid mixed pipeline, a buffer tank, a spray head, a circulating pipeline and a water outlet pipeline, wherein the water supply pipeline, the mixer, the booster pump, the gas-water mixed liquid pipeline, the buffer tank, the spray head and the circulating pipeline are sequentially connected; and the gas supply pipeline, the mixer, the booster pump, the gas-water mixed liquid pipeline, the buffer tank, the spray head and the circulating pipeline are sequentially connected. By controlling the flow of a water supply pipeline, a gas supply pipeline, a spray head and a circulating pipeline, the pressure rise of a booster pump is controlled, the inclination angle of the spray head, the axial interval of the spray head and the like are swung, gas-water mixed liquid is in continuous contact, collides and effectively shears, and then micron bubbles or micro-nano bubbles or nano bubbles are generated and adjusted. The method disclosed by the invention has important theoretical value and practical significance for quickly improving water environments such as rivers, lakes and reservoirs and eliminating all black and odorous water.

Description

technical field [0001] The invention belongs to the field of water environment treatment such as river courses, lakes and reservoirs, and specifically relates to a micro-nano bubble generator and an adjustment method with adjustable bubble particle diameters. Background technique [0002] In recent years, with the rapid development of China's economy, excessive sewage and waste water have entered rivers, lakes and other water environments through various channels, which has far exceeded the pollution-holding capacity of rivers, resulting in a large increase in organic matter in water, and dissolved oxygen sharply decreased, and produced NH under the action of microorganisms 3 -N, humus, H 2 S, CH 4 and R-SH and other odorous substances and blackening substances such as FeS and MnS, thereby causing black and odorous phenomena. While damaging the image of the city, the black and odorous water body endangers the safety of the ecological environment and causes unpredictable p...

AI Technical Summary

Problems solved by technology

While the black and odorous water damages the image of the city, it also endangers the safety of the ecological environment and causes unpredictable physical and mental harm to the residents living around.

[0003] The black and odorous water body is mainly caused by the lack of oxygen in the water body. Although the traditional aeration can increase the dissolved oxygen in the water body, it cannot achieve the characteristics of large comparative area, long residence time in water, and air flotation to increase the transparency of the water body when using micro-nano bubbles.

At present, the methods for generating micro-nano bubbles mainly include ultrasonic cavitation method, hydraulic cavitation method, electrochemical method, container pump method, etc., all of which have the disadvantages of high cost, large volume, complex structure, poor durability, etc., and cannot be processed according to different treatment stages. Adjust the bubble particle size according to the demand for bubble particle size, which limits its nationwide promotion and use to a certain extent
