Description

Technical Field

[0001] This utility model relates to the field of air filter technology, specifically to an integrated adsorption and catalysis air filter. Background Technology

[0002] An air filter is a device used to purify air. Its core function is to remove various pollutants from the air and make the output air meet specific cleanliness standards. An air filter generally consists of a shell, an air inlet, an air outlet, and an adsorption layer.

[0003] Adsorption layers are generally single adsorption materials that can only adsorb pollutants in the air. Some bacteria, viruses and other microorganisms attached to the adsorption material may be re-spread into the environment with airflow, threatening human health. Although some air filters also have catalytic layers, the combination of adsorption and catalytic layers is relatively simple, usually just simple stacking, which leads to uneven airflow in the filter, affecting the full contact between pollutants and adsorption and catalytic materials, and reducing purification efficiency. Therefore, an integrated adsorption and catalytic air filter is needed. Utility Model Content

The adsorption and catalysis unit includes a frame, a honeycomb skeleton, honeycomb pores, adsorbent material, and catalytic material. The honeycomb skeleton is made of lightweight, high-temperature resistant ceramic material. Honeycomb pores are uniformly formed between the honeycomb skeletons.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0016] Please see Figure 1-4 One embodiment of this utility model is an integrated adsorption-catalysis air filter, comprising: a housing 1, and further comprising... Air inlet 2 is located at the center of one side of housing 1, and air outlet 7 is located at the center of the side of housing 1 away from air inlet 2. Flanges 3 are provided on the side of the air inlet 2 and the air outlet 7 away from the housing 1, and fasteners are provided around the flanges 3. The air inlet 2 and air outlet 7 are connected to the air inlet pipe and the air outlet pipe. The fan is fixed on the air inlet pipe. When running, it will draw polluted air from the air inlet 2 into the inside of the housing 1. An air distribution plate 4 is provided inside the housing 1 on one side of the air inlet 2, and air distribution holes are evenly distributed on the air distribution plate 4. The air first passes through the air distribution plate 4, and the air distribution holes on the air distribution plate 4 evenly disperse the airflow, so that the air forms a stable laminar flow before filtration, reducing the impact on the internal components. The adsorption catalytic unit 6 is uniformly distributed inside the shell 1, and the adsorption catalytic unit 6 includes a frame 8 and a honeycomb skeleton 9, with the honeycomb skeleton 9 all disposed inside the frame 8. The adsorption catalysis unit 6 also includes honeycomb pores 10, which are uniformly formed between the honeycomb skeleton 9, and adsorption material 11 and catalytic material 12 are arranged sequentially from the inside to the outside of the honeycomb pores 10. Both the frame 8 and the honeycomb skeleton 9 are made of lightweight, high-temperature resistant ceramic materials, which reduces the overall weight of the adsorption catalytic unit 6 and makes it easier to transport and install. The connecting groove 13 is provided at the four corners on one side of the frame 8, and the four corners on the side of the frame 8 away from the connecting groove 13 are provided with connecting blocks 14. The contact surface between the connecting groove 13 and the connecting block 14 is provided with a sealing strip 20, and the sealing strip 20 is made of silicone. Adjacent adsorption catalytic units 6 are engaged with connecting grooves 13 via connecting blocks 14. The sealing strips 20 on the contact surfaces prevent air leakage and connect the honeycomb holes 10 to form independent "micro-reaction channels". Air can only flow within the honeycomb holes 10. When air flows along the honeycomb holes 10, it first comes into contact with the adsorption material 11 on the inner wall. The adsorption material 11 is a modified activated carbon fiber with nano-sized titanium dioxide particles loaded on its surface. The microporous structure of the activated carbon fiber captures particulate matter such as dust and PM2.5. The nano-sized titanium dioxide particles enhance the adsorption capacity for organic pollutants such as formaldehyde and benzene. The adsorbed pollutants diffuse to the outer catalytic material 12. The catalytic material 12 is a manganese dioxide catalyst loaded with precious metals platinum and palladium. The organic pollutants undergo an oxidation reaction on the surface of the catalytic material 12 and decompose into water and carbon dioxide, so that the pollutants in the air can fully contact the material, thereby improving the adsorption and catalytic decomposition effect. The frame 8 above the connecting groove 13 is provided with grooves 16, and the inside of the grooves 16 is uniformly provided with limit blocks 18 through the reset spring 17. The connecting block 14 is provided with a limit groove 15 on the side near the limit block 18. Preferably, support members 5 are provided at both ends inside the shell 1, the adsorption catalytic unit 6 is disposed between the support members 5, electromagnets 19 are uniformly embedded inside the support members 5, and the electromagnets 19 are all on the same vertical line as the limiting blocks 18, and the limiting blocks 18 are all made of magnetic material. When the connecting block 14 is inserted into the connecting groove 13, the limiting groove 15 on the connecting block 14 passes the limiting block 18. Under the action of the return spring 17, the limiting block 18 pops out and locks into the limiting groove 15, realizing automatic locking and increasing the stability of the connection between the adsorption catalytic units 6. When disassembling, the electromagnet 19 can be energized, and the magnetic limiting block 18 can be pulled to separate from the limiting groove 15 to release the lock. After that, the adsorption catalytic unit 6 can be disassembled. The specific model and specifications of electromagnet 19 need to be determined based on the specifications and parameters of the device. The selection and calculation method is existing technology, so it will not be described in detail here.

[0017] Working Principle: In this embodiment, the air intake and exhaust pipes are connected via the air inlet 2 and air outlet 7. The fan is fixed to the air intake pipe. During operation, polluted air is drawn into the housing 1 through the air inlet 2. The air first passes through the air distribution plate 4, whose air distribution holes evenly disperse the airflow, preventing excessively high local flow rates or short circuits. The evenly dispersed air then enters the adsorption catalytic unit 6. Each adsorption catalytic unit 6 is supported by a honeycomb skeleton 9 supported by a frame 8. Honeycomb holes 10 are evenly formed within the honeycomb skeleton 9. Adjacent adsorption catalytic units 6 are engaged with connecting slots 13 via connecting blocks 14. Sealing strips 20 on the contact surfaces prevent airflow leakage, connecting the honeycomb holes 10 to form independent "micro-reaction channels." Air can only flow within the honeycomb holes 10. As the air flows along the honeycomb holes 10, it first contacts the adsorption material 11 on the inner wall. The adsorption material 11 is modified activated carbon fiber with nano-sized titanium dioxide particles loaded on its surface. The microporous structure of the activated carbon fiber captures dust and PM2.5. The nano-sized titanium dioxide particles enhance the adsorption capacity for organic pollutants such as formaldehyde and benzene. The adsorbed pollutants diffuse to the outer catalytic material 12, which is a manganese dioxide catalyst loaded with precious metals platinum and palladium. The organic pollutants undergo an oxidation reaction on the surface of the catalytic material 12, decomposing into water and carbon dioxide, allowing the pollutants in the air to fully contact the material, thus improving the adsorption and catalytic decomposition effect. In addition, when the connecting block 14 is inserted into the connecting groove 13, the limiting groove 15 on the connecting block 14 passes the limiting block 18. Under the action of the return spring 17, the limiting block 18 pops out and locks into the limiting groove 15, realizing automatic locking and increasing the stability of the connection between the adsorption catalytic units 6. When disassembling, the electromagnet 19 can be energized, and the magnetic limiting block 18 can be pulled away from the limiting groove 15 to release the lock. After that, the adsorption catalytic unit 6 can be disassembled.
