Problems solved by technology

However, the ozone contact reaction tank currently in use has the following shortcomings. The ozone microbubbles or ultramicrobubbles released by the aeration device are small in size and slow in rising speed, causing the ozone bubbles to accumulate on the surface of the aeration device for a long time. localized area, so the closer the location of the aeration device, the higher the concentration of ozone
Since sewage or tap water generally contains bromide ions, the long residence time of the fluid in the local area near the surface of the aeration device will cause some water bodies to absorb excessive ozone and form bromate, which is seriously harmful to human health. Problems that have been difficult to solve in the ozone oxidation water treatment system
At the same time, due to the long-term accumulation of ozone microbubbles in the lower part of the fluid, the concentration of ozone microbubbles in the upper fluid is not enough to fully react with ozone, which also leads to uneven system response and affects the fluid treatment effect.
In addition, the existing equipment is not highly integrated and takes up a lot of space

Embodiment 1

[0030] see figure 1As shown, the present invention provides an ozone generation control device, comprising a main tank 1, the top of the main tank 1 is provided with a detachable cover plate 7, the cover plate 7 is provided with an emptying port 6, the main tank 1 is provided with an inner cylinder 3, the lower end of the inner cylinder 3 is fixed with the bottom surface of the main pipe, the upper end of the inner cylinder 3 is lower than the height of the main tank 1 and the upper end is open, and the bottom of the main tank 1 is provided with a communication with the inner cylinder 3. There is a first spacer 2 between the main tank 1 and the inner cylinder 3, the upper end of the first spacer 2 is fixed with the bottom surface of the cover plate 7, and the lower end of the first spacer 2 is connected to the main tank. There is a gap between the bottom surfaces of the 1, the upper end side of the first spacer 2 is provided with a pressure equalizing port 5, and the height of...

Embodiment 2

[0033] see figure 2 As shown, this embodiment is further improved on the basis of Embodiment 1. In this embodiment, a detachable first spacer is added in the slow flow channel 12 between the first spacer 2 and the inner cylinder 3 The flow damper 13, by adding the first damper 13, can further lengthen the purification process and purification time of the sewage, and further improve the sewage purification effect, and the first damper 13 is also easy to install and disassemble, which is convenient for later maintenance. .

[0034] Three preferred structures and installation methods of the first damper 13 are provided below:

[0035] 1) see image 3 and Figure 4 As shown, the first damper 13 includes a first sleeve 17 and a second sleeve 21 disposed inside the first sleeve 17 , between the upper end of the first sleeve 17 and the upper end of the second sleeve 21 And the lower end of the first sleeve 17 and the lower end of the second sleeve 21 are connected and fixed by e...

Embodiment 3

[0039] see Figure 10 As shown, this embodiment is further improved on the basis of implementation 2. In this embodiment, a second damper 14 is added in the slow flow channel 12 between the first spacer 2 and the main tank 1. The structure of the second damper 14 can be the same as any one of the three first dampers 13 provided in the second embodiment. The flow damper 14 can be matched with the installation space between the first spacer 2 and the main tank 1 .

[0040] see Figure 11 As shown, the present invention also provides an ozone generation control system, including an ozone generator 15, an air pump 16 connected to the ozone generator 15 and the aforementioned ozone generation control device, the aeration coil 8 is connected to the air pump through a pipeline The gas outlet end of 16 is connected, and ozone gas is supplied into the inner cylinder 3 by the ozone generator 15 . The ozone generation control system can effectively reduce the generation of bromate whe...
