Description

Technical Field

[0001] This invention relates to the field of ozone water preparation technology, and in particular to a small-volume pressure tank for preparing high-concentration ozone mother liquor. Background Technology

[0002] High-concentration ozone mother liquor is a high-content stable ozone system formed by efficiently dissolving ozone gas in a specific solvent. Unlike ordinary ozone water, it inhibits ozone decomposition through solvent complexation, micro-nano encapsulation and other technologies, resulting in an ozone concentration far higher than that of conventional aqueous solutions. Moreover, its storage stability is greatly improved. This mother liquor can be diluted as needed and can quickly release ozone molecules while retaining its core characteristics of strong oxidation, sterilization and pollutant degradation. It is widely used in water treatment, industrial oxidation, disinfection and other fields, and represents a convenient and efficient form of ozone application.

[0003] High-pressure ozone mother liquor preparation typically employs large-volume dissolving tanks, utilizing a high-pressure environment to enhance ozone solubility. The ozone dissolving device disclosed in patent ZL202122475477.3 uses a general-purpose dissolving tank with an operating pressure of 0.6-1.0 MPa. However, small-volume pressure tanks may be used to prepare high-concentration ozone mother liquor of 300-500 mg / L.

[0004] Existing small-volume tanks have a fast liquid turnover rate, which can easily lead to large fluctuations in the concentration of the mother liquor. Furthermore, the general pressure parameters cannot meet the requirements for preparing high-concentration mother liquor, requiring a larger circulation flow rate, which can easily exceed the equipment's capacity. The matching relationship between the circulation flow rate and the mother liquor addition flow rate is not clear, resulting in insufficient ozone dissolution and serious local overconcentration.

[0005] Therefore, it is necessary to provide a small-volume pressure vessel for preparing high-concentration ozone mother liquor to solve the above-mentioned technical problems. Summary of the Invention

Detailed Implementation

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0036] First Embodiment

[0037] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of the small-volume pressure tank for preparing high-concentration ozone mother liquor provided by the present invention; Figure 2 A schematic diagram of the installation structure is provided for this invention; Figure 3 A schematic diagram of the cross-shaped turbulence tube is provided for this invention; Figure 4 Provided for the present invention Figure 3 An enlarged view of point A shown; Figure 5 Provided for the present invention Figure 3 The enlarged view at point B is shown. The small-volume pressure vessel for preparing high-concentration ozone mother liquor includes: mounting base 1;

[0038] The pressure tank body 4 is mounted on the top of the mounting base 1 via a bracket 2. Multiple slowing components 16 are installed inside the pressure tank body 4.

The aeration component 15 is installed at the top center of the cross-shaped turbulence component 3, which does not affect the normal operation of the cross-shaped turbulence component 3.

[0041] Using a small-volume pressure tank as the core reaction vessel, high-concentration ozone mother liquor is prepared through five steps: equipment debugging, parameter setting, mother liquor preparation, concentration monitoring and adjustment, and mother liquor output. Debugging requires ensuring the sealing and rated parameters of the pressure tank, ozone generator, and circulation components. The operating pressure is set to 1.0-1.2 MPa, and the circulation flow rate is set to 6-10 times the dosage flow rate. During preparation, turbulence is created inside the tank through the circulation component, and ozone bubbles are dispersed by the aeration component. The concentration is monitored and dynamically adjusted throughout the process. During output, circulation operation is maintained. The system is equipped with a pressure tank with a pressure of 1.6 MPa, a circulation component with a rated flow rate of 150 m³ / h, an ozone generator with a maximum gas production of 5 kg / h, and an aeration component with an 8 μm pore size. The initial settings are 1.2 MPa pressure and 50 m³ / h circulation flow rate. The circulation components are started to bring the flow velocity inside the tank to 2.7 m / s. The ozone generator is turned on and the bubbles released by the aeration components are mixed and dissolved. If the concentration is too low, the power of the ozone generator is increased. If the water quality changes, such as the temperature rises, the pressure or circulation flow rate is increased accordingly. Finally, the mother liquor concentration deviation can be controlled within ±7 mg / L to meet the preparation requirements.

The fixing frame 152 is used to install the aeration structure 153 on the top of the cross turbulence assembly 3, and the connecting pipe 151 is used to connect the bottom end of the air inlet pipe 5 to the inlet of the aeration structure 153.

[0055] Aeration structure 153 is an existing aeration disc used to evenly discharge ozone.

[0056] The working principle of the small-volume pressure tank for preparing high-concentration ozone mother liquor provided by this invention is as follows:

[0057] Multiple conical deceleration components 16 are installed inside the pressure tank body 4. These components allow ozone-containing liquid or pure liquid to slowly descend after entering the pressure tank body 4, thereby increasing the contact time between ozone and the liquid and improving the preparation effect. The cross-shaped turbulence component 3 and the circulation component 9 work together to allow the liquid near the bottom of the pressure tank body 4 to rise, achieving circulation and increasing the contact time between ozone and the liquid reaction, thus improving the preparation effect. During the liquid inlet process, the liquid inlet component 7 allows the liquid to be evenly and dispersedly delivered into the pressure tank body 4, reducing liquid impact. Combined with the deceleration components 16, this slows down the liquid's descent speed. In actual use, the liquid is first transported from the liquid inlet assembly 7 into the interior of the pressure tank body 4. With the help of the slowing assembly 16, the liquid can fall layer by layer. During this process, the air supply assembly 6 injects ozone from the bottom of the pressure tank body 4 through the aeration assembly 15, allowing the ozone and liquid to come into full contact. At the same time, the cross turbulence assembly 3 injects the liquid from the bottom of the inner wall of the pressure tank body 4 from the bottom up. With the help of the circulation assembly 9, the liquid can move upward inside the pressure tank body 4. At the same time, the liquid at the bottom can be drawn out from the bottom of the pressure tank body 4 and injected from the top to complete the liquid circulation. The mother liquor after completion can be discharged through the mother liquor discharge pipe 11.

[0058] Compared with related technologies, the small-volume pressure tank for preparing high-concentration ozone mother liquor provided by the present invention has the following beneficial effects:

[0059] To improve the preparation effect of high-concentration ozone mother liquor inside a small-volume pressure tank, multiple conical slow-moving components 16 are installed inside the pressure tank body 4. These components allow the ozone-containing liquid or pure liquid to slowly descend after entering the pressure tank body 4, thereby increasing the contact time between ozone and liquid and improving the preparation effect. The cross-shaped turbulence component 3 and the circulation component 9 work together to allow the liquid near the bottom of the pressure tank body 4 to rise and circulate, further increasing the contact time between ozone and liquid and improving the preparation effect. Meanwhile, the liquid inlet component 7 ensures that the liquid is evenly and dispersedly delivered to the pressure tank body during the liquid inlet process. Inside body 4, liquid impact is reduced, and the slowing component 16 slows down the liquid's descent. This design allows for full contact between the liquid and ozone, improving the preparation effect of high-concentration ozone mother liquor inside the small pressure tank body 4. At the same time, precise parameter control and turbulent dissolution design achieve a mother liquor concentration deviation of ≤±10mg / L, completely solving the problem of large concentration fluctuations in small-volume tanks. Turbulence combined with the microbubbles of the aeration component allows the ozone dissolution to far exceed the theoretical value, stably preparing 300-500mg / L supersaturated mother liquor. The small-volume pressure tank body design avoids equipment overload; if applied to large-volume tanks, energy consumption would increase significantly.

[0060] Second Embodiment

[0061] Please refer to the following: Figures 6-7 - Figure 8 , Figure 6 A schematic diagram of the structure of a second embodiment of the small-volume pressure tank for preparing high-concentration ozone mother liquor provided by the present invention; Figure 7 A schematic diagram of the structure of the filter assembly is provided for this invention; Figure 8 Provided for the present invention Figure 7 The enlarged view at point C shows a small-volume pressure vessel for preparing high-concentration ozone mother liquor, based on the first embodiment of this application. The second embodiment of this application proposes another small-volume pressure vessel for preparing high-concentration ozone mother liquor. The second embodiment is merely a preferred embodiment of the first embodiment, and its implementation will not affect the independent implementation of the first embodiment.

[0062] Specifically, the difference between the small-volume pressure vessel for preparing high-concentration ozone mother liquor provided in the second embodiment of this application and the one described herein is as follows: Please refer to... Figure 6 and Figure 7 A filter tank 18 is installed at the bottom end of the mother liquor discharge pipe 11, and a connecting pipe 19 is installed at the bottom end of the filter tank 18. A filter assembly 17 is installed inside the filter tank 18.

[0063] A flange is installed at the bottom of the connecting pipe 19, and the filter assembly 17 can filter impurities.

[0064] Please refer to Figure 6 , Figure 7 and Figure 8 The filter assembly 17 includes a conical interceptor 171, a drain pipe 172, and a drain valve 173. The drain pipe 172 is installed at the bottom end of the conical interceptor 171, and the drain valve 173 is installed at the other end of the drain pipe 172.

[0065] The conical interceptor 171 is installed inside the filter tank 18.

[0066] Compared with related technologies, the small-volume pressure tank for preparing high-concentration ozone mother liquor provided by the present invention has the following beneficial effects:

[0067] To improve the buffering and filtration effect at the outlet during the mother liquor discharge process, a filter tank 18 with a connecting pipe 19 is installed at the bottom of the mother liquor discharge pipe 11. Inside the filter tank 18, a self-cleaning filter component 17 is installed. After the mother liquor is discharged from the mother liquor discharge pipe 11, it enters the filter tank 18. The filter component 17 can reduce the liquid flow rate and filter out impurities in the liquid. It only needs to be cleaned by opening the drain valve 173 periodically. This design reduces the discharge speed of the mother liquor and filters the mother liquor for convenient subsequent use.
