Description

Technical Field

[0001] This invention relates to the field of air purification equipment technology, and more specifically to a detachable air purifier that synergistically purifies multiple pollutants. Background Technology

[0002] Background technology of air purifiers In industrial production and specific working environments, the air is often mixed with various pollutants such as water vapor, ozone, volatile organic compounds (VOCs), and particulate matter. These pollutants not only corrode the precision components of production equipment, affecting the stability of equipment operation, service life, and product quality, but also have adverse effects on the health of workers who are in this environment for a long time, causing respiratory diseases, skin irritation, and other problems, seriously restricting industrial production efficiency and the safety of the working environment.

[0003] Currently, many existing air purification devices suffer from a single-function limitation, typically targeting only one or a subset of pollutants. This makes it difficult to meet the practical needs of industrial production and specific work environments for the synergistic purification of multiple pollutants. For example, dedicated dehumidifiers can only remove water vapor from the air and cannot effectively treat pollutants such as ozone, VOCs, and particulate matter; ozone converters focus solely on the decomposition of ozone and have no effect on purifying other pollutants; and simple particulate filters can only intercept particulate matter and cannot solve the pollution problems caused by water vapor, ozone, and VOCs.

[0004] To address the aforementioned issue of limited functionality, some existing technologies attempt to integrate multiple purification functions, designing equipment capable of purifying multiple pollutants. However, such equipment generally suffers from drawbacks such as complex structure and inconvenient maintenance. Specifically, the various purification modules within the equipment are often integrated internally using a fixed connection method. When a purification module fails, reaches the end of its service life, or requires replacement of consumables, the entire equipment must be completely disassembled. This process is cumbersome, time-consuming, and labor-intensive. Furthermore, the equipment cannot operate normally during disassembly, severely impacting purification efficiency and failing to meet the continuous purification needs of industrial production and specific working environments.

[0005] Furthermore, existing equipment with multiple purification functions does not fully consider the adverse effects of high moisture content on subsequent purification modules, resulting in a tendency for purification performance to degrade. Moisture in the air easily adheres to the surfaces of subsequent ozone decomposition, VOC adsorption, and particulate matter filtration modules. This moisture adhesion reduces the activity of the ozone decomposition catalyst, leading to decreased ozone decomposition efficiency; it reduces the adsorption capacity of activated carbon and other adsorption materials, shortening the lifespan of adsorption modules and affecting VOC purification; and it causes moisture to clog the filter media in the particulate matter filtration module, reducing particulate matter interception efficiency. Ultimately, this leads to a significant decline in the overall purification performance of the equipment, making it impossible to achieve long-term, stable, and efficient synergistic purification of multiple pollutants.

[0006] In summary, existing air purification equipment suffers from problems such as limited functionality, complex structure, inconvenient maintenance, and easy degradation of purification performance. It is difficult to meet the needs of industrial production and specific working environments for efficient synergistic purification of multiple pollutants, convenient maintenance, and long-term stable operation. Therefore, developing an air purifier with a simple structure, convenient maintenance, and the ability to achieve efficient synergistic purification of multiple pollutants has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] In view of this, the present invention provides a detachable air purifier for the synergistic purification of multiple pollutants, which can achieve efficient purification of multiple pollutants, while facilitating the maintenance of each module and the replacement of consumables.

[0008] The technical solution adopted in this invention is as follows: A detachable air purifier that synergistically purifies multiple pollutants includes a water removal section, an ozone removal section, a VOC adsorption section, and a particulate matter filtration section connected sequentially along the airflow direction. The sections are detachably connected by quick-release clamps. The dewatering section includes a conical section with a wide center and tapering ends, and cylindrical sections at both ends of the conical section. A drain valve is provided at the point where the inner diameter of the conical section is at its maximum. The deodorization section is filled with structured filler loaded with precious metals. The VOC adsorption section is filled with granular activated carbon. The particulate matter filtration section is equipped with a non-woven fabric filter layer.

[0009] Furthermore, the quick-release clamp includes an open annular clamp body, fastening bolt handles connected to both ends of the clamp body, and clamp gasket with a filter screen; The connection ends of the water removal section, ozone removal section, VOC adsorption section and particulate matter filtration section are all provided with annular bosses that match the quick-release clamps.

[0010] The clamp gasket with filter screen is attached to the mating surface of the annular boss.

[0011] Furthermore, the dewatering section is equipped with a stainless steel wire mesh, which has a multi-layer structure. The mesh size of each layer decreases sequentially along the airflow direction. The stainless steel wire mesh is wrapped and fixed, and the outer wall of the stainless steel mesh is fixed within the dewatering section by O-rings.

[0012] Furthermore, the taper of the tapered segment is 10°-30°.

[0013] Furthermore, the structured packing is a honeycomb metal carrier loaded with precious metals, and the structured packing is fixed by O-rings.

[0014] Furthermore, the activated carbon is in the form of columnar particles with a particle size of 2-5 mm, and a breathable non-woven fabric pad is provided around the activated carbon.

[0015] Furthermore, the nonwoven filter layer includes meltblown nonwoven fabric and a frame. The meltblown nonwoven fabric is placed inside the frame. The filtration accuracy of the meltblown nonwoven fabric is H11 or higher. The meltblown nonwoven fabric adopts a folded structure. The frame is fixed by O-rings.

[0016] Beneficial effects: 1. This invention, through the sequential arrangement of a water removal section, an ozone removal section, a VOC adsorption section, and a particulate matter filtration section, specifically removes water vapor, ozone, VOCs, and particulate matter from the air, solving the problem of the single purification function of existing equipment and achieving synergistic purification of multiple pollutants; among them, the water removal section prioritizes the removal of water vapor, avoiding adverse effects of water vapor on the performance of subsequent ozone decomposition catalysts, activated carbon, and non-woven fabrics, thereby improving the overall purification efficiency; Secondly, each functional section is detachably connected by quick-release clamps. When consumables (such as activated carbon or air filter) of a certain section need to be replaced or components need to be repaired, the corresponding section can be disassembled separately without disassembling the entire equipment, making the operation simple and efficient. The conical water collection structure of the dewatering section, in conjunction with the drain valve, can promptly discharge the intercepted water without frequent disassembly of the dewatering section, making maintenance highly convenient.

[0017] 2. Each functional section of this invention adopts industrially mature purification materials and structural designs, such as stainless steel wire mesh, structured fillers loaded with precious metals, activated carbon, and non-woven air filter elements. The materials are readily available and have stable performance. The segmented structure facilitates production and assembly, reducing manufacturing costs.

[0018] 3. The filter consumables filled in the water removal section shell, the ozone removal section shell, the VOC adsorption section shell and the particulate matter filtration section shell of the present invention are all limited and fixed by O-rings, and at the same time, they are sealed to prevent gas short circuits.

[0019] 4. The non-woven filter layer of this invention adopts a folded structure, which can increase the filtration area and extend the service life. Attached Figure Description

Detailed Implementation

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] This invention provides a detachable air purifier for synergistic purification of multiple pollutants, such as... Figure 1 , Figure 2 As shown, it includes a water removal section 1, an ozone removal section 2, a VOC adsorption section 3, and a particulate matter filtration section 4 connected sequentially along the airflow direction. The sections are detachably connected by quick-release clamps 5.

[0025] The quick-release clamp 5 includes an open annular clamp body 51, fastening bolt handles 52 connected to both ends of the clamp body, the fastening bolt handles being used to adjust the clamping force of the clamp body, and a clamp gasket 53 with a filter screen; the connecting ends of the water removal section 1, the ozone removal section 2, the VOC adsorption section 3, and the particulate matter filtration section 4 are all provided with annular bosses 6 that match the quick-release clamp 5, and the clamp gaskets with filter screens are attached to the mating surface of the annular bosses 6 to perform filtration between the sections.

[0026] The clamp body 51 is made of stainless steel, the clamp gasket 53 with filter screen is made of PTFE, the filter screen is made of stainless steel with a mesh size of 50, the clamp can be quickly tightened or loosened by turning the fastening bolt handle 52, so as to realize the disassembly and installation of each section. After connection, the sealing performance is good and there is no air leakage.

[0027] In this embodiment, each segment is a cylindrical shell made of stainless steel, with an inner diameter of 200mm and lengths of 400mm, 400mm, 400mm and 100mm respectively.

[0028] Specifically, the dewatering section 1 includes a conical section with a wide center and tapering ends, and cylindrical sections at both ends of the conical section. The conical section serves as a water collection structure 12, with a taper of 10°-30°. A drain valve is welded at the point of maximum inner diameter at the center of the conical section. A stainless steel wire mesh 11 is installed inside the dewatering section. This stainless steel wire mesh 11 has a multi-layered structure, with the mesh size decreasing sequentially along the airflow direction. The stainless steel wire mesh is fixed by O-rings. In this embodiment, the stainless steel wire mesh 11 has three layers along the airflow direction, with mesh sizes of 80 mesh, 120 mesh, and 200 mesh, respectively. The three layers of stainless steel wire mesh are wrapped and fixed together. The stainless steel mesh has a certain hardness and yield strength, effectively resisting plastic deformation under stress. The inner wall of the dewatering section 1 has two grooves, with O-rings fixed inside each groove. The outer wall of the stainless steel mesh is tightly fixed to the inner wall of the housing through the O-rings. The inner diameter of the O-rings is 3mm smaller than the outer diameter of the stainless steel mesh, which prevents displacement and facilitates the replacement of stainless steel wire mesh consumables. The tapered section has a taper of 10°, and the drain valve 13 is a DN15 copper drain valve, which is a manual ball valve and can be opened periodically to drain the collected water.

[0029] The deodorization section 2 is filled with structured packing material loaded with precious metals. The structured packing material 21 is a honeycomb metal carrier with 0.3% platinum-palladium alloy (mass ratio 1:1) loaded on the surface of the carrier. The inner wall of the deodorization section 2 is designed with two grooves, and O-rings are fixed inside the grooves. The honeycomb metal carrier is fixed to the inner wall of the shell by the O-rings. The inner diameter of the O-rings is 3mm smaller than the outer diameter of the structured packing material 21, which can prevent displacement and facilitate the replacement of filter media.

[0030] The VOC adsorption section 3 is filled with granular activated carbon 31, which is wrapped in a metal mesh. The activated carbon particles have a columnar structure with a diameter of 2-5 mm; in this embodiment, 3-4 mm activated carbon is used. A 10 mm thick breathable non-woven fabric pad 32 is provided around the activated carbon 31 fixed by the metal mesh to prevent activated carbon dust from escaping with the airflow. The inner wall of the VOC adsorption section 3 has two grooves, with O-rings fixed inside each groove. The metal mesh is fixed to the inner wall of the shell by the O-rings. The inner diameter of the O-rings is 3 mm smaller than the outer diameter of the metal mesh, which prevents displacement and facilitates replacement.

[0031] The particulate matter filtration section 4 is equipped with a non-woven fabric filter layer 41, with a filtration accuracy of H11 or higher. In this embodiment, the non-woven fabric filter layer 41 includes H12 grade meltblown non-woven fabric and a frame. The meltblown non-woven fabric inside the frame adopts a folded structure. The inner wall of the particulate matter filtration section 4 is designed with two grooves, and O-rings are fixed inside the grooves. The frame is fixed to the inner wall of the shell by close contact with the O-rings. The inner diameter of the O-rings is 3mm smaller than that of the non-woven fabric frame, which can prevent displacement and facilitate replacement.

[0032] The working process of this embodiment is as follows: Polluted air containing water vapor, ozone, VOCs and particulate matter first enters the water removal section 1. Through the interception and condensation effect of the multi-layer stainless steel wire mesh 11, water vapor forms water droplets and falls into the water collection structure 12, and is discharged periodically by opening the drain valve 13; the air after water removal enters the ozone removal section 2. Under the action of the structured packing material 21 loaded with precious metals, ozone is catalytically decomposed into oxygen; then the air enters the VOC adsorption section 3, where activated carbon 31 physically adsorbs VOCs; finally, the air passes through the non-woven fabric filter layer 41 of the particulate matter filtration section 4, where particulate matter is intercepted, and the purified air is discharged.

[0033] Tests showed that the air purifier in this embodiment has a water vapor removal rate of ≥90%, an ozone decomposition rate of ≥99%, a VOC removal rate of ≥85%, and a particulate matter (PM2.5) removal rate of ≥99.5% when the air volume is 500m³ / h, meeting the purification requirements for multiple pollutants; the disassembly and replacement time for each section does not exceed 5 minutes, and the ease of maintenance is significantly better than that of existing integrated equipment.

[0034] In summary, the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
