Description

Technical Field

[0001] This utility model relates to the field of waste gas purification, and in particular to a device for purifying waste gas from the production of safety helmets. Background Technology

[0002] Safety helmet production exhaust gas purification devices are environmentally friendly equipment specifically designed to treat the exhaust gases generated during the production of safety helmets. These exhaust gases may contain harmful substances, particulate matter, volatile organic compounds (VOCs), etc., posing a threat to the environment and worker health. In practice, many safety helmet manufacturers have already adopted exhaust gas purification devices to treat the exhaust gases generated during the production process. These devices effectively reduce the concentration of exhaust gas emissions, protecting the environment and worker health.

[0003] The exhaust gas purification device disclosed in Chinese utility model patent (Announcement No.: CN220194382U) includes a filter box. An exhaust gas inlet pipe is fixedly connected to the left side surface of the filter box, a drain pipe is fixedly connected to the bottom right side surface of the filter box, and an electric shock device is fixedly connected to the top left side surface of the filter box. It filters solid particles through a carbon base plate fixedly installed below the filter box cover and within the filter box cavity, and a filter cloth plate fixedly installed to the right of the carbon base plate. An activated carbon layer fixedly connected to the right side of the filter cloth plate filters harmful molecules, and an exhaust pipe fixedly connected to the right side of the activated carbon layer plate facilitates the delivery of gas into water.

[0004] Although the above technical solution uses a carbon base plate and a filter cloth plate fixedly installed on the right side of the carbon base plate to filter solid particles, the activated carbon and filter screen treatment method cannot effectively remove all harmful substances in the exhaust gas, especially the removal effect of some volatile organic compounds (VOCs) is poor, and the long-term operating cost is high. Therefore, a safety helmet production exhaust gas purification device is proposed. Utility Model Content

A filter mechanism for filtering exhaust gas is installed on one side of the catalytic treatment box 1, and a condensation mechanism for cooling exhaust gas is provided on the other side of the catalytic treatment box 1. A flow divider plate 5 is fixed inside the catalytic treatment box 1, and a plurality of flow divider holes 6 are opened inside the flow divider plate 5. A purification mechanism for purifying exhaust gas is installed on the inner wall of the catalytic treatment box 1. Through the plurality of small flow divider holes 6 opened on the flow divider plate 5, the exhaust gas can be evenly discharged through the flow divider holes 6, thereby ensuring the uniformity of exhaust gas flow.

[0032] Reference Figure 1 and Figure 2 The filtration mechanism includes a mounting plate 2, which is placed on one side of the catalytic treatment box 1. The mounting plate 2 has a mounting pipe 21 that communicates with the catalytic treatment box 1 on one side. The mounting plate 2 has a fixing bolt 22 that is threadedly connected to the catalytic treatment box 1 installed inside. The mounting plate 2 can be disassembled by the fixing bolt 22, and then the mounting pipe 21 can be disassembled to facilitate the maintenance of the internal parts.

[0033] A coarse filter 23 is fixed inside the mounting pipe 21. A fine filter 24, which is fixed to the mounting pipe 21, is provided on one side of the coarse filter 23. A water-absorbing filter element 25, which is fixed to the mounting pipe 21, is provided on the right side of the fine filter 24. An air inlet pipe 3 is connected to one side of the mounting pipe 21. The coarse filter 23 is made of stainless steel wire mesh, and the fine filter 24 is made of polyester fiber material. It can filter impurities in the exhaust gas. The water-absorbing filter element 25 is made of hydrophilic activated carbon fiber, which can adsorb moisture in the exhaust gas.

[0034] The condensation mechanism includes a condenser 4, which is connected to the other side of the catalytic treatment box 1. Several heat conduction pipes 41 are installed inside the condenser 4. When the exhaust gas enters the condenser 4, the heat in the exhaust gas is absorbed by the heat conduction pipes 41. The upper surface of the heat conduction pipes 41 passes through the condenser 4 and is fixed with heat dissipation fins 42. A fixing plate 43 is installed on the upper surface of the heat dissipation fins 42. Two heat dissipation fans 44 are fixed inside the fixing plate 43. Heat is transferred to the heat dissipation fins 42. The heat dissipation fans 44 installed on the fixing plate 43 can dissipate heat from the heat dissipation fins 42, thereby dissipating the heat in the exhaust gas.

[0035] Reference Figure 1 , Figure 2 and Figure 3The purification mechanism includes a catalyst 7, which is installed on the inner wall of the catalytic treatment box 1. The lower end of the catalyst 7 is provided with a fixing block 71 that is snapped into the catalytic treatment box 1. When the exhaust gas passes through the catalyst filled inside the catalyst 7, the oxidation efficiency of VOCs can be improved, making the exhaust gas purification more thorough.

[0036] The upper surface of the catalyst element 7 is provided with a fixing groove 72, and one side of the condenser element 4 is connected to an exhaust pipe 8. With the help of the fixing block 71 and the fixing groove 72, the catalyst element 7 can be disassembled and replaced.

[0037] The implementation principle of this utility model is as follows: Before using the exhaust gas purification device and method for the safety helmet production, the catalytic treatment box 1 is first placed in a suitable position, then the inlet pipe 3 is connected to the external exhaust pipe, and then the exhaust pipe 8 is connected to the external auxiliary suction equipment. During use, the exhaust gas enters the installation pipe 21 through the inlet pipe 3. The coarse filter 23 inside the installation pipe 21 is made of stainless steel wire mesh, and the fine filter 24 is made of polyester fiber material, which can filter impurities in the exhaust gas. The water-absorbing filter element 25 is made of highly hydrophilic activated carbon fiber, which can adsorb moisture in the exhaust gas. This combination ensures filtration efficiency while taking into account the durability and cost of the materials. Furthermore, the installation plate 2 can be disassembled by the fixing bolts 22 on the installation plate 2, and then the installation pipe 21 can be disassembled for easy access to the internal components. After maintenance of the parts, the filtered exhaust gas enters the catalytic treatment box 1. Through several small diversion holes 6 on the diversion plate 5, the exhaust gas can be evenly discharged through the diversion holes 6. The catalyst filled inside the catalytic element 7 can improve the oxidation efficiency of VOCs, making the exhaust gas purification more thorough. With the help of the fixed block 71 and the fixed groove 72, the catalytic element 7 can be disassembled for easy replacement. The diversion holes 6 in the catalytic oxidation zone have an optimized flow channel design, reducing dead zones in the exhaust gas flow and enhancing the contact efficiency between the catalyst and the exhaust gas. After purification, the exhaust gas enters the condenser 4. The heat in the exhaust gas is absorbed by the heat conduction pipe 41 and transferred to the heat dissipation fins 42. The heat dissipation fan 44 on the fixed plate 43 can dissipate heat from the heat dissipation fins 42, thereby dissipating the heat in the exhaust gas.

Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
