Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to an air purification device that includes a catalyst that can be heated and regenerated. Background Technology

[0002] An air purifier is a device that can remove impurities and purify polluted air. Most simple air purifiers can achieve the effect of air purification simply by being equipped with a filter.

[0003] Some air purification devices incorporate catalysts to improve air purification efficiency. These catalysts can be reused through heating regeneration. However, activated carbon filter components in the filtration system cannot be regenerated by heating, requiring disassembly and cleaning. This cleaning process is difficult and costly, affecting the overall performance.

[0004] Therefore, it is necessary to propose an air purification device that includes a catalyst that can be heated and regenerated. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an air purification device that includes a catalyst that can be heated and regenerated. It has the advantages of being able to simultaneously heat and regenerate the catalyst and activated carbon filter components, thereby improving their performance, and also introducing a pretreatment method to enhance the air purification effect, thus solving the problems mentioned in the background technology.

[0006] This utility model provides the following technical solution: an air purification device with a catalyst that can be heated and regenerated, comprising a pretreatment chamber and a heated catalyst chamber:

[0007] The pretreatment chamber is movably connected to a support frame. The upper and lower sides of the support frame are respectively movably connected to mounting frame one and mounting frame two. Dry filter cotton is installed inside mounting frame one, and activated carbon filter plate is installed inside mounting frame two. U-shaped support frames are fixedly connected to both sides of the heating catalytic chamber. Precious metal catalyst is installed inside the U-shaped support frames. Multiple sets of heating rods are installed inside the heating catalytic chamber.

[0008] Preferably, a connecting pipe 1 and a connecting pipe 2 are installed on the bottom sides of the pretreatment box and the heating catalytic box, respectively, and a one-way valve is installed on both the connecting pipe 1 and the connecting pipe 2.

[0009] Preferably, the upper surface of the pretreatment box is provided with a slot, a top cover is inserted into the slot, and a slot is provided on the opposite side wall of the slot. An L-shaped block is engaged in the slot, and the other end of the L-shaped block is fixedly connected to the upper surface of the support frame.

[0010] Preferably, slots are provided at the middle of the upper and lower sides of the supporting frame, and the two sides of the second mounting frame and the first mounting frame are respectively engaged with the inside of the slots. Bolts are threadedly connected to the connection between the second mounting frame and the first mounting frame and the slots.

[0011] Preferably, an inlet pipe is installed on the top of the top cover, and the other end of the inlet pipe is connected to a gas source.

[0012] Preferably, a gas discharge pipe is installed on the top of the heating catalytic chamber, and a liquid discharge pipe is installed on the bottom side of the heating catalytic chamber.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This air purification device, which includes a catalyst with heatable regeneration, works as follows: During air purification, gas enters the pretreatment chamber and first comes into contact with the dry filter cotton inside, which adsorbs large particles and moisture. Then, an activated carbon filter further adsorbs impurities, pre-treating the gas. The gas is then sent to the heated catalytic chamber, where a heating rod raises the temperature. This, combined with a precious metal catalyst, enables a catalytic combustion reaction, producing harmless substances such as carbon dioxide and water. Over extended use, the heating rod generates heat; when the temperature reaches the regeneration temperature, the precious metal catalyst and activated carbon filter can be regenerated. The dry filter cotton can be disassembled for external cleaning to ensure optimal performance. This design effectively purifies the air, and the regenerable precious metal catalyst and activated carbon filter maximize their utilization, extending their lifespan and improving air purification efficiency.
