Description

Technical Field

[0001] This utility model relates to the field of wastewater disinfection technology, specifically to a device for increasing ozone reaction efficiency. Background Technology

[0002] Ozone treatment of wastewater is a highly efficient method of advanced treatment. Due to its advantages such as strong oxidation capacity, ease of use, and no secondary pollution, it has been widely used in the field of wastewater disinfection.

[0003] Most existing ozone treatment systems lack efficient ozone dispersion and mixing mechanisms, resulting in uneven distribution of ozone gas in wastewater. Some areas have excessively high ozone concentrations while others receive insufficient contact, thus reducing ozone utilization and potentially leading to ineffective ozone consumption. Therefore, optimizing the mixing method between ozone and wastewater to improve ozone diffusion efficiency, thereby enhancing wastewater disinfection effects and reducing operating costs, has become a pressing issue in current ozone wastewater disinfection technology. Utility Model Content

[0004] To address the aforementioned technical deficiencies, this invention provides a device for increasing ozone reaction efficiency, enabling wastewater to mix evenly and efficiently with ozone, thereby improving ozone reaction efficiency.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A device for increasing ozone reaction efficiency includes a rectangular box. One side of the rectangular box is provided with a downwardly inclined first guide plate evenly spaced from top to bottom, and another side is provided with a downwardly inclined second guide plate evenly spaced from top to bottom. The first and second guide plates are arranged alternately, and both sides of the first and second guide plates are fixedly connected to the sidewalls of the rectangular box, forming a meandering flow channel. The uppermost first guide plate is spaced along its upward inclined direction... The rectangular box is equipped with baffles that gradually increase in height, with both ends of the baffles fixedly connected to the side walls of the rectangular box. A water inlet pipe with a regulating valve is located on the top of the rectangular box on the side with the highest baffle. An exhaust pipe with an ozone catalytic decomposer is located on the top of the rectangular box on the side with the lowest baffle. A drain pipe and a microporous aerator are located at the bottom of the rectangular box, with a control valve on the drain pipe. A filter, dryer, air compressor, and ozone generator are sequentially connected outside the rectangular box, with the ozone generator's outlet connected to the microporous aerator via a pipe.

[0006] The principle of this device is that the microporous aerator releases ozone microbubbles from the bottom, which achieves preliminary mass transfer with the sewage at the bottom. The stepped baffles at the top regulate the water flow distribution, making it more uniform. Then, the staggered No. 1 and No. 2 guide plates form a meandering channel, which prolongs the gas-liquid contact time and improves the ozone reaction efficiency.

[0007] Preferably, the tilt angle between the first guide plate and the second guide plate is 2°. A smaller tilt angle will significantly reduce the flow velocity of the sewage on the first and second guide plates, thereby greatly prolonging the contact time between ozone and sewage, which is beneficial to improving the ozone dissolution rate and reaction efficiency.

[0008] Furthermore, water level sensors are installed on the bottom side wall of the rectangular box, one above the other. The water level sensors are electrically connected to the controller. The control valve on the drain pipe is an electromagnetic control valve, which is electrically connected to the controller to achieve precise water level control.

[0009] Furthermore, the lower edges of the No. 1 and No. 2 guide vanes are equipped with diversion columns at intervals. The diversion columns evenly separate the water flow, facilitating the rise of ozone.

[0010] The device for increasing ozone reaction efficiency obtained by this invention has the following beneficial effects: the microporous aerator can efficiently disperse ozone gas and achieve preliminary mass transfer with the sewage at the bottom; the staggered arrangement of No. 1 and No. 2 guide plates forms a meandering flow channel, which extends the gas-liquid contact path; and the stepped design of the top baffle further optimizes the water flow distribution, significantly improving the ozone dissolution efficiency and reaction rate.

[0015] Example 1:

[0016] like Figure 1 , 2As shown in Figure 3, this utility model discloses a device for increasing ozone reaction efficiency, including a rectangular box 17. One side of the rectangular box 17 has a first guide plate 9 evenly spaced downwards from top to bottom, and the other side has a second guide plate 10 evenly spaced downwards from top to bottom. The first and second guide plates 9 and 10 are arranged alternately, and both sides of the first and second guide plates 9 and 10 are fixedly connected to the sidewalls of the rectangular box 17, forming... The meandering flow channel features diversion columns 16 spaced at the lower edges of guide plates 9 and 10. The inclination angle between guide plates 9 and 10 is 2°. This smaller inclination angle significantly reduces the flow velocity of wastewater on guide plates 9 and 10, thereby greatly extending the contact time between ozone and wastewater, which is beneficial for improving ozone dissolution rate and reaction efficiency. On the uppermost guide plate 9, diversion columns 16 are spaced at intervals along its upward inclination direction. A gradually increasing baffle 13 is fixedly connected to the side wall of a rectangular box 17 at both ends. A water inlet pipe 12 is installed at the top of the rectangular box 17 on the side where the highest baffle 13 is located. A regulating valve 11 is installed on the water inlet pipe 12, allowing sewage to enter through the water inlet pipe 12, and the regulating valve 11 adjusts the flow rate. An exhaust pipe 14 is installed at the top of the rectangular box 17 on the side where the lowest baffle 13 is located, and an ozone catalytic decomposer 15 is installed on the exhaust pipe 14. A drain pipe 6 and a microporous aerator 5 are installed at the bottom of the rectangular box 17. An electromagnetic control valve 7 is installed on the drain pipe 6. Water level sensors 8 are installed one above the other on the side wall at the bottom of the rectangular box 17. The water level sensors 8 and the electromagnetic control valve 7 are electrically connected to a controller. The controller controls the electromagnetic control valve 7 to control the sewage discharge based on the water level sensors 8, achieving precise water level control. A filter 1, a dryer 2, an air compressor 3, and an ozone generator 4 are sequentially connected outside the rectangular box 17. The outlet of the ozone generator 4 is connected to the microporous aerator 5 through a pipe.

[0017] The principle of this device is that the microporous aerator 5 releases ozone microbubbles from the bottom, which achieves preliminary mass transfer with the sewage at the bottom. The stepped baffle 13 at the top regulates the water flow distribution, making it more uniform. Then, the staggered first guide plate 9 and second guide plate 10 form a meandering flow channel, which prolongs the gas-liquid contact time and improves the ozone reaction efficiency.
