Furthermore, the amount of solvent added is easily deviated from the control during the preparation process, causing fluctuations in the solvent ratio and content. Frequent manual adjustments are required to stabilize the solvent content, leading to high production costs for hydrogen peroxide. Utility Model Content

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0026] The components of the embodiments of this application described and illustrated in the accompanying drawings can be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of this application provided in the drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application.

[0029] Unless otherwise specified, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which the various embodiments of this application pertain. Terms (such as those defined in commonly used dictionaries) shall be interpreted as having the same meaning as in their contextual meaning in the relevant technical field and shall not be construed as having an idealized or overly formal meaning, unless clearly defined in the various embodiments of this application.

[0030] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] Reference Figure 1 , Figure 1 This is a schematic diagram of a hydrogen peroxide production system provided in this embodiment. The system mainly includes:

[0032] Organic solvent tank 100, dosing tank 200, solid carrier storage tank 300, stirred tank 400 and concentration detection equipment 500.

[0033] The organic solvent tank 100 is mechanically connected to the stirred tank 400 via a first valve, the solid carrier storage tank 300 is mechanically connected to the stirred tank 400 via a second valve 800, the dosing tank 200 is mechanically connected to the stirred tank 400 via a third valve, the concentration detection device 500 is disposed in the cavity of the stirred tank 400, and the concentration detection device 500 is communicatively connected to the third valve.

[0034] Among them, the first valve, the second valve 800, and the third valve can be flow valves. The opening size and opening time of each valve can be fixed in advance, thereby ensuring that the dosage added to the stirred tank 400 from the organic solvent tank 100, the solid carrier storage tank 300, and the dosing tank 200 is fixed or controllable each time. The opening time of each valve can be controlled by a microcontroller or by a timer or other device.

[0035] During the operation of the hydrogen peroxide production system, the first valve controls the organic solvent tank 100 to output a first dose of organic solvent to the stirred tank 400. The organic solvent tank 100 typically stores organic solvents used to prepare hydrogen peroxide, such as trioctyl phosphate, C9 heavy aromatics, 2-ethylanthraquinone, or catalysts. The dosage of organic solvent added varies depending on the concentration of hydrogen peroxide being produced; therefore, the first valve can be opened first to inject the organic solvent into the stirred tank 400 as needed.

[0036] In addition to organic solvents, the preparation of hydrogen peroxide also requires a solid carrier, such as anthraquinone, isopropanol, cyclohexanol, and 1-phenylethanol. The dosage of the solid carrier needs to be determined based on the dosage of the organic solvent. Alternatively, a second dosage of solid carrier can be injected into the stirred tank 400 first, and then, based on the second dosage, the first valve can be controlled to inject a first dosage of organic solvent into the stirred tank 400, so that the ratio of organic solvent to solid carrier is a preset ratio.

[0037] After adding both the organic solvent and the solid carrier to the stirred tank 400, the stirred tank 400 can be controlled to stir, ensuring thorough mixing and reaction of the organic solvent and the solid carrier to obtain the initial hydrogen peroxide. The initial concentration of hydrogen peroxide may differ from the target concentration. Therefore, the concentration of the initial hydrogen peroxide can be detected by a concentration detection device in the stirred tank 400. If the concentration is lower than the target concentration, the third valve is opened based on the concentration information, causing the dosing tank 200 to output a third dose of hydrogen peroxide into the stirred tank 400. The hydrogen peroxide concentration in the dosing tank 200 is generally relatively high.

[0038] For example, if the product is medical-grade hydrogen peroxide, the concentration of commonly used medical disinfectant hydrogen peroxide is generally only 3%-5%. Therefore, the concentration of hydrogen peroxide stored in the dosing tank 200 can be higher than this value, for example, 20%-30%. When the concentration of hydrogen peroxide in the stirred tank 400 is lower than 3%-5%, the high-concentration hydrogen peroxide in the dosing tank 200 can be added to the stirred tank 400, and then the mixed solution and the high-concentration hydrogen peroxide are stirred through the stirred tank 400 to obtain hydrogen peroxide of the target concentration.

[0039] In this embodiment, the material storage tank for preparing hydrogen peroxide is controlled by valves. Each valve obtains the dosage of material input into the mixing vessel 400 by other valves, and then controls the opening of the material storage tank connected to it, thereby accurately controlling the proportion of various materials, resulting in better efficiency and more accurate concentration in hydrogen peroxide production.

[0040] In one embodiment, the hydrogen peroxide production system further includes a deionized water storage tank 900, which is connected to the stirred tank 400.

[0041] The deionized water storage tank 900 is used to open when the temperature data in the stirred tank 400 exceeds the alarm temperature threshold, so as to inject deionized water into the stirred tank 400.

[0042] The deionized water storage tank 900 stores deionized water. The deionized water can dilute the hydrogen peroxide in the stirred tank 400 when the concentration in the stirred tank 400 is higher than the preset concentration. It can also cool the stirred tank 400 when the temperature data in the stirred tank 400 is higher than the alarm temperature threshold.

[0043] In one embodiment, the number of organic solvent tanks 100 includes a plurality, and each organic solvent tank 100 is connected to the stirring vessel 400 through a corresponding first valve.

[0044] like Figure 1As shown, the organic solvent tank 100 includes a first solvent tank 101 and a second solvent tank 102. The first valve includes a first sub-valve 600 and a second sub-valve 700. The first sub-valve 600 is mechanically connected to the first solvent tank 101, and the second sub-valve 700 is mechanically connected to the second solvent tank 102. The first sub-valve 600 and the second sub-valve 700 are communicatively connected.

[0045] The first sub-valve 600 is used to control the first solvent tank 101 to output a first preset dose of the first organic solvent, and is also used to generate a first control signal according to the first preset dose and send the first control signal to the second sub-valve 700;

[0046] The second sub-valve 700 is used to control the second solvent tank 102 to output a second preset dose of organic solvent according to the first control signal; the first solvent tank 101 is any one of the plurality of organic solvent tanks 100, and the second solvent tank 102 is any one or more of the organic solvent tanks 100 other than the first solvent tank 101.

[0047] When preparing hydrogen peroxide, there may be a variety of organic solvents required, and the ratio of different organic solvents needs to be controlled according to the requirements. Therefore, one type of organic solvent can be injected into the stirred tank 400 through a valve first, and the opening time of the other valves can be controlled according to the dosage of the first injected organic solvent, so as to ensure that the ratio of various organic solvents is correct.

[0048] In one embodiment, the hydrogen peroxide production system further includes a timing device, which is communicatively connected to the control device of the stirring tank 400;

[0049] The timing device is used to time the stirring time of the mixing vessel 400;

[0050] The control device for the mixing vessel 400 is used to control the mixing vessel 400 to stop mixing after the mixing time reaches the preset time.

[0051] The mixing time of the mixing vessel 400 can be preset, and the timer can be started when the mixing vessel 400 starts mixing, until the preset mixing time is reached and then the mixing vessel 400 is controlled to stop mixing.

[0052] In this embodiment, the stirring time of the stirred tank 400 is controlled by a timing device, so that the organic solvent and solid carrier in the stirred tank 400 are fully mixed and reacted, thereby improving the generation efficiency of hydrogen peroxide.

[0053] In one embodiment, the hydrogen peroxide production system further includes a temperature detection device and a stirring tank 400 control device, wherein the temperature detection device is communicatively connected to the stirring tank 400 control device, and the stirring tank 400 control device is communicatively connected to the stirring tank 400.

[0054] The temperature detection device is used to detect the temperature data in the stirring vessel 400 and feed the temperature data back to the control device of the stirring vessel 400;

[0055] The control device for the stirred tank 400 is used to control the stirred tank 400 to stop stirring when the temperature data reaches a preset temperature threshold.

[0056] During the preparation of hydrogen peroxide, the organic solvent and the solid carrier undergo a chemical reaction, which generates heat. If the dosage of the added organic solvent and solid carrier is too large or the ratio is inaccurate, the temperature in the stirred tank 400 may exceed the safe temperature, i.e., reach the preset temperature threshold.

[0057] Therefore, a temperature detection device can be installed inside or outside the mixing vessel 400 to detect the temperature in the mixing vessel 400 in real time. When the temperature reaches the preset temperature threshold, the mixing vessel 400 can be controlled to stop mixing even if the mixing time has not reached the preset time, so as to prevent the temperature in the mixing vessel 400 from continuing to rise.

[0058] Similarly, other parameter detection devices, such as pressure detection devices, can be installed inside or outside the mixing vessel 400 to detect the pressure in the mixing vessel 400. When the pressure exceeds the preset pressure threshold, the mixing vessel 400 can be controlled to stop mixing and trigger an alarm.

[0059] In one embodiment, the hydrogen peroxide production system further includes an alarm device, which is communicatively connected to the temperature detection device.

[0060] The temperature detection device is used to send an alarm signal to the alarm device when it detects that the temperature data in the stirring tank 400 is greater than the alarm temperature threshold.

[0061] The alarm device is used to trigger an alarm based on the alarm signal.

[0062] To ensure the safety of equipment and personnel during the hydrogen peroxide production process, an alarm must be triggered immediately if an abnormal temperature is detected in the mixing tank 400, so that staff can promptly cool down or vent the mixing tank 400.

[0063] In one embodiment, the hydrogen peroxide production system further includes a drain pipe connected to the bottom of the stirred tank 400;

[0064] The drain pipe is used to open when the temperature data in the stirred tank 400 exceeds the alarm temperature threshold.

[0065] When the temperature in the stirred tank 400 exceeds the alarm temperature threshold, in order to prevent the organic solvent and solid carrier in the stirred tank 400 from continuing to react, deionized water can be injected into the stirred tank 400 to cool it down, while the drain pipe at the bottom of the stirred tank 400 is opened to drain the solution out of the stirred tank 400, thereby ensuring the safety of the equipment and personnel.

[0066] In one embodiment, the hydrogen peroxide production system further includes a temperature control device connected to the stirring vessel 400.

[0067] In an optional embodiment, the temperature control device includes a heating jacket or a cooling jacket that covers the outer surface of the stirred tank 400.

[0068] In the production of hydrogen peroxide, in order to accelerate the reaction between the organic solvent and the solid carrier, a heating device, such as a heating jacket, can be used to heat the stirred tank 400. When the temperature in the stirred tank 400 is too high, a corresponding cooling device, such as a cooling jacket, can be used to cool the stirred tank 400.

[0069] In the various embodiments of this application, the functional modules or units can be integrated together to form an independent part, or each module can exist independently, or two or more modules can be integrated to form an independent part.

[0070] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
