AI Technical Summary
The symmetrical distribution of releasers in existing air-floating systems results in a ‘dead zone’ of liquid flow, with less mixing and exchange efficiency.
A multi-stage release mechanism is designed to form a multi-stage release of dissolved water by providing the first and second dissolved water releases side by side in the contact area, thereby promoting a flow pattern from the bottom to the top.
This avoids the formation of ‘dead zones’ during flow, improves the mixing and exchange efficiency, and ensures uniform mixing of liquids in the entire pool.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air flotation equipment, in particular to a multi-stage release mechanism. Background Art
[0002] Dissolved air flotation is a method widely used for solid-liquid separation in industrial wastewater and urban sewage treatment. The large number of dense microbubbles formed by the dissolved air system float the suspended matter in the reaction tank, collect it and discharge it. The releasers on the current flotation system are symmetrically distributed on both sides of the reaction tank. This distribution method will cause the liquid to tend to flow along a symmetrical path, forming a stable flow pattern. This symmetry can lead to the formation of "dead zones" - areas where the liquid flows slowly or stagnates, resulting in low mixing and exchange efficiency. For this reason, we propose a multi-stage release mechanism. Utility Model Content

[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Refer to the attached Figure 1-4, a multi-stage release mechanism, including an air flotation tank 1 and a contact zone 2, the air flotation tank 1 extends into the contact zone 2 through a pipeline, the three-way pipe connected to the pipeline divides it into two and communicates with the same first release pipe, the first release pipe is connected to the bottom of the contact zone 2 through an extension pipe and is connected to N number of first dissolved air water releasers 3, the first release pipe is also connected to a branch pipe, the branch pipe is connected to a second release line connection, the second release pipeline is connected to the bottom of the contact zone 2 through an extension pipe and is connected to N-1 number of second dissolved air water releasers 4, the dissolved air water releaser is a device that releases high-pressure dissolved air into the contact zone 2, by controlling the release of dissolved air and the flow of solution in the contact zone 2, the solid, liquid or gas suspended in the solution is brought to the water surface, thereby achieving the effect of purifying water quality and separating substances, the first dissolved air water releaser 3 and the second dissolved air water releaser 4 are arranged side by side in the contact zone 2, and the height difference between the first dissolved air water releaser 3 and the second dissolved air water releaser 4 in the contact zone 2 can be adjusted according to specific process requirements. , the dissolved gas water is released in multiple stages, and the multiple stage release can make the whole pool full of dissolved gas water, so that the solids suspended in the water can be better accelerated to float up, avoid forming a "dead zone" during flow, and improve the mixing and exchange efficiency. The branch pipe is also connected with a release valve body, and the flow rate of the dissolved gas water flowing into the release valve body can be changed by adjusting the release valve body. The mixing and exchange efficiency is further improved by changing the flow rate of the dissolved gas water. The first dissolved gas water releaser 3 and the second dissolved gas water releaser 4 are both the same dissolved gas water releasers, which include a dissolved gas water chamber 31 and a radiation pipe 32 equidistantly arranged on the dissolved gas water chamber 31. The bottom of the radiation pipe 32 is also connected with a spray pipe 33, and the drain port of the spray pipe 33 faces the bottom of the contact area 2. When the dissolved gas water is introduced, the dissolved gas water is not only distributed from the surroundings of the dissolved gas water chamber 31, but also distributed at the bottom of the radiation pipe 32. This can promote the flow pattern from the bottom to the top, which is helpful to further mix and exchange the liquid in the pool, avoid the occurrence of dead zones or stratification phenomena, and the structure of the mechanism is simple and convenient, and easy to disassemble. It greatly reduces the labor intensity of personnel, shortens the downtime of customer sites, and increases the utilization rate of equipment.
