Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to a hydrogen peroxide purification device. Background Technology

[0002] Hydrogen peroxide, as an important inorganic chemical raw material, is widely used in many fields such as papermaking, textiles, chemical synthesis, military industry, electronics, food processing, pharmaceuticals, cosmetics, environmental protection, and metallurgy. Currently, the anthraquinone process is commonly used to produce hydrogen peroxide both domestically and internationally. This method uses anthraquinone derivatives as a working carrier and obtains an aqueous solution of hydrogen peroxide through steps such as hydrogenation, oxidation, and extraction. However, with the expansion of its application fields, some fields such as caprolactam and propylene oxide production have put forward higher requirements for the concentration and purity of hydrogen peroxide.

[0003] In the field of hydrogen peroxide purification, many existing purification devices generally follow a specific process flow. Typically, evaporation and concentration are performed first, followed by filtration, in order to obtain a high-purity hydrogen peroxide solution. However, in practical applications, this traditional process sequence has revealed some significant shortcomings, the most prominent being unsatisfactory preparation efficiency. Due to limitations in the connection between the evaporation and concentration steps and the filtration process, or in the process design, the entire purification process is time-consuming and energy-efficient, ultimately resulting in a relatively low overall preparation efficiency, which is insufficient to meet the growing demand for high-efficiency production. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a hydrogen peroxide purification device, which solves the technical problems of low preparation efficiency and complex structure.

[0005] Technical Solution: To achieve the above objectives, this utility model provides the following technical solution: A hydrogen peroxide purification device, comprising: a filtration section for filtering hydrogen peroxide, the filtration section including a first filter plate, the side of the first filter plate being connected to the inner wall of the filtration section; a second filter plate disposed directly below the first filter plate, the side wall of the second filter plate being connected to the inner wall of the filtration section; an ultrafiltration membrane plate disposed directly below the second filter plate, the side of the ultrafiltration membrane plate being connected to the inner wall of the filtration section; an atomizer located on the filtration section for atomizing hydrogen peroxide to ensure uniform distribution of hydrogen peroxide within the filtration section; and a centrifugal water pump motor located directly below the filtration section and connected to the filtration section for extracting the atomized hydrogen peroxide from the filtration section. All of the above devices are in a sealed state.

[0006] In a further embodiment, the feed pipe needs to be made of a material with good sealing performance and corrosion resistance.

[0007] In a further embodiment, the material of the liquid guide tube is the same as that of the feed tube, both of which need to be made of a material with good sealing performance and corrosion resistance.

[0008] In a further embodiment, the material holding section is located on one side of the filtration section and is connected to the other end of the liquid guiding pipe; the evaporation section is located directly below the material holding section; the heating wire can be an armored heating wire or a ceramic heating wire, the former having better corrosion resistance and insulation properties, and the latter having good corrosion resistance and high temperature performance.

[0009] In a further embodiment, a cooling section is located on one side of the material holding section, and the cooling section holds cooling material; a cooling pipe is located inside the cooling section, and the cooling pipe is used to guide hydrogen peroxide.

[0010] In a further embodiment, the air guide pipe is connected at one end to the material holding part and at the other end to the cooling pipe.

[0011] In a further embodiment, the cooling pipes are arranged in a spiral shape.

[0012] In a further embodiment, the materials of the first filter plate and the second filter plate can be polypropylene (PP), polyethylene (PE), etc., and the pore size of the filter pores on the filter plate can be 160-250 micrometers, 100-160 micrometers, 70-100 micrometers, etc.

By optimizing the combination of key components such as the filter section, atomizer and centrifugal water pump motor, efficient filtration and purification of hydrogen peroxide are achieved; compared with the traditional process, this utility model adopts the process sequence of filtration first and then concentration, which avoids the possible decomposition of hydrogen peroxide during the evaporation and concentration process, and reduces the clogging problem in the filtration step, thereby improving the overall preparation efficiency.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] Reference Figure 1-4 A hydrogen peroxide purification device includes: a filter section 1 for filtering hydrogen peroxide, the filter section 1 including a first filter plate 4, the side of the first filter plate 4 being connected to the inner wall of the filter section 1, a second filter plate 5 disposed directly below the first filter plate 4, the side wall of the second filter plate 5 being connected to the inner wall of the filter section 1, an ultrafiltration membrane plate 6 disposed directly below the second filter plate 5, the side of the ultrafiltration membrane plate 6 being connected to the inner wall of the filter section 1; an atomizer 2 located on the filter section 1 for atomizing hydrogen peroxide to make the hydrogen peroxide evenly distributed in the filter section 1; and a centrifugal water pump motor 7 located directly below the filter section 1 and connected to the filter section 1 for extracting the atomized hydrogen peroxide in the filter section 1.

[0025] The cooperation between the various devices and structures mentioned above helps to improve the efficiency and quality of filtration and subsequent treatment.

[0026] Feed pipe 3 is connected to atomizer 2 at one end and is used for feeding hydrogen peroxide.

[0027] Hydrogen peroxide can be introduced into the atomizer 2 through the feed pipe 3.

[0028] The liquid guide tube 8 is located on the centrifugal water pump motor 7, and one end is connected to the output end of the centrifugal water pump motor 7.

[0029] The flow path of the hydrogen peroxide extracted by the centrifugal pump motor 7 can be guided by the liquid guide tube 8.

[0030] The material holding section 9 is located on one side of the filter section 1, and the material holding section 9 is connected to the other end of the liquid guide tube 8; the evaporation section 10 is located directly below the material holding section 9; multiple heating wires 1001 are provided, and the heating wires 1001 are evenly distributed in the material holding section 9, and the heating wires 1001 are connected to the evaporation section 10.

[0031] The evaporation of hydrogen peroxide can be achieved through the cooperation between the feeding section 9, the evaporation section 10, and the heating wire 1001.

[0032] Cooling section 12 is located on one side of material holding section 9, and cooling section 12 holds cooling material; cooling pipe 1201 is located inside cooling section 12, and cooling pipe 1201 is used to guide hydrogen peroxide.

[0033] Through the cooperation between the cooling section 12 and the cooling pipe 1201, the hydrogen peroxide can be cooled and liquefied.

[0034] The air guide pipe 11 is connected at one end to the material holding part 9 and at the other end to the cooling pipe 1201.

[0035] The vaporized hydrogen peroxide can be introduced into the cooling section 12 through the air guide pipe 11.

[0036] The cooling pipes 1201 are arranged in a spiral shape.

[0037] The spiral cooling pipe 1201 can increase the contact area with the cooling material inside the cooling section 12.

[0038] The pore size of the filter holes in the first filter plate 4 and the second filter plate 5 gradually decreases.

[0039] Through the cooperation between the first filter plate 4 and the second filter plate 5, the vaporized hydrogen peroxide can be filtered step by step.

[0040] During use, hydrogen peroxide enters the atomizer 2 through the feed pipe 3 and is atomized, so that it can be more evenly distributed in the filter section 1. It is filtered and purified by passing through the first filter plate 4, the second filter plate 5 and the ultrafiltration membrane plate 6 in sequence. The centrifugal water pump motor 7 draws out the filtered atomized hydrogen peroxide and sends it to the material collection section 9 through the liquid guide pipe 8. The multiple heating wires 1001 in the material collection section 9 heat and evaporate the hydrogen peroxide under the action of the evaporation section 10. The evaporated gas enters the cooling section 12 through the gas guide pipe 11 and is liquefied by the cooling material in the cooling pipe 1201.

[0041] The control system, waste treatment module, and temperature and concentration monitoring device required for the aforementioned filtration device are all existing technologies and are not essential technical features in this application. Therefore, they are not described or drawn in the documents and drawings of this application.

[0042] In summary, compared with existing technologies, this device has the following advantages: It atomizes hydrogen peroxide using an atomizer and uses the suction generated by the centrifugal pump motor to make the atomized hydrogen peroxide flow downwards, passing through a multi-layer filtration structure to achieve filtration. Furthermore, the process of filtering before concentration removes impurities and solid particles from the hydrogen peroxide before concentration, reducing potential localized overheating and clogging issues during concentration, thus lowering the risk of hydrogen peroxide decomposition. Simultaneously, the device integrates filtration, concentration, and cooling functions, reducing equipment complexity and floor space requirements, lowering equipment costs, and simplifying maintenance.
