Micro-nano sparkling water treatment device

Abstract

The invention relates to a micro-nano sparkling water treatment device. A water inlet pipe, a mixing chamber, a water outlet pipe and an aeration head are sequentially mounted in the water input and water output direction. The water inlet is communicated with an air inlet pipe and a multistage pump, and an on-off valve is arranged on the air inlet pipe. The mixing chamber comprises a plurality ofinlets and outlets opposite to the inlets, the inlets and the outlets are formed in the mixing chamber, and each inlet and each outlet are communicated with the multistage pump and a bubble generatorrespectively. The water outlet pipe is communicated with the bubble generator, and fluid is transported to the aeration head through the water outlet pipe, the bubble generator comprises a cylinder, the cylinder is provided with an inlet and an outlet, and the wall of an inner cavity of the cylinder is fixedly connected with a plurality of baffle layers A which are alternately arranged at intervals. The aeration head comprises a body, the body comprises an inlet section and an outlet section communicated with the inlet section, a water dividing plate is arranged at the transition position of the inlet section and the outlet section, the water dividing plate is in interference fit with the inner wall of the outlet section, the outlet section is connected with a water dividing head, and thewater dividing head is sleeved with a cover connected with the body. According to the technical scheme, more small bubbles can be constantly generated in the operation process, and the pollution control effect is good.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a micro-nano bubble water treatment device. Background technique [0002] With the development of industry and economy and urbanization, my country's water resources are facing the problems of resource shortage and serious pollution. In the pollution of open water systems, the collapse of the water system ecosystem caused by water trophication accounts for a large proportion. The most effective means to solve the eutrophication of water bodies are water body oxygenation and air flotation. Compared with the traditional method of injecting macroscopic bubbles, micro-nano bubble water treatment technology, as the name implies, injects micro-bubbles into water. Due to the small size of the bubbles, the bubbles rise slowly in the water, have a long residence time, and have high dissolution efficiency. Negative charge and rich in strong oxidizing hydroxyl radicals (OH) and othe...

Problems solved by technology

[0003] At present, the production method of micro-nano bubbles in the market mainly uses pumps to inhale gas and liquid separately to mix, and then mix the mixed gas-liquid, cut and destroy water molecules to generate bubbles. The formed bubbles are mainly macromolecular bubble water, which cannot be circulated. produce more and smaller bubbles. The particle size of the macromolecular bubble water produced by the prior art can reach 100-300 microns. However, when the macromolecular bubble water purifies sewage, it is extremely easy to rupture in the sewage due to the large contact area. At the moment when the bubbles burst, dissolved oxygen is released, and the particles in the sewage are decomposed, and the bubbles are easy to burst, which will lead to excessive release of dissolved oxygen, that is, the amount of dissolved oxygen released per unit area exceeds the amount of dissolved oxygen required to decompose particles, and the dissolved oxygen is excessive. Saturated, the excess dissolved oxygen will escape into the air, resulting in insufficient oxygen content in the water body, and also shortens the time for dissolved oxygen to exist in the water body, which cannot achieve the effect of oxygenation and pollution control.
