Description

Technical Field

[0001] This invention relates to the field of air purification technology, and in particular to a multi-stage combinable porous media air purification device. Background Technology

[0002] An air purification device is a device used to remove impurities from the air. It is widely used in industrial manufacturing, building ventilation and other fields to improve air quality and protect equipment from pollution damage.

[0003] In existing technologies, air purification devices typically use filters or centrifugal separators to capture dust, combined with simple structures to handle moisture. Multi-stage filters are generally used to adsorb dust, and condensate is collected in a bottom water collection tank. However, in such air purification devices, dust is easily forced into the equipment's circulation system by high-speed airflow. Once this dust is sucked into the equipment, it accumulates at vents or heat dissipation components for extended periods, causing blockages in ventilation channels, reducing heat dissipation efficiency, and ultimately triggering high-temperature alarms or even system failure.

[0004] To solve these problems, a multi-stage combinable porous media air purification device needs to be designed. Summary of the Invention

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] like Figures 1 to 8 The multi-stage combinable porous media air purification device shown includes: a dust removal and drainage module 1, a separation module 2, and a hydrophobic module 3. The dust removal and drainage module 1 has a first storage space 11 and a second storage space 12; the separation module 2 is installed within the first storage space 11 of the dust removal and drainage module 1; the hydrophobic module 3 is installed within the second storage space 12 of the dust removal and drainage module 1. Dust-laden and water-laden gas enters from the separation module 2 end, is further purified by the hydrophobic module 3, and then flows out. The dust removal and drainage module 1 also has a drain outlet 14 and a dust outlet 13, which are located at the bottom of the dust removal and drainage module 1 and are respectively located in their corresponding first storage space 11 and second storage space 12. Figures 1 to 3 As shown, the dust removal and drainage module 1 serves as the basic frame, internally divided into a first storage space 11 and a second storage space 12, which are isolated from each other. It should be noted that the separation module 2 and the hydrophobic module 3 can be installed in various ways in this device, such as through slots or bolts, depending on the specific application requirements. The separation module 2 is integrated into the first storage space 11 and is used to capture dust particles in the gas; the hydrophobic module 3 is installed in the second storage space 12 and is responsible for intercepting and condensing liquid pollutants in the gas. During gas flow, the gas first flows through the separation module 2 to complete dust separation, then enters the hydrophobic module 3 for liquid removal, and finally the purified gas flows out.

[0026] In this embodiment, the present invention independently installs the separation module 2 and the hydrophobic module 3 in the first storage space 11 and the second storage space 12 of the dust discharge and drainage module 1, and provides independent dust discharge port 13 and drainage port 14 at the bottom of the module, thereby realizing the physical separation and timely discharge of dust and liquid. Compared with the prior art, this structural arrangement avoids the impact of dust and liquid on the device body and ensures the long-term stable operation of the device in a high-speed airflow environment.

[0027] In an embodiment of the present invention, a first ramp 131 is provided at the dust discharge port 13, and the first ramp 131 extends from the first storage space 11 to the dust discharge port 13 at a certain angle. Figure 3 As shown, the first ramp 131 transitions naturally from the inner wall of the first storage space 11 to the outlet end of the dust discharge port 13 at a specific angle, forming a continuous guide surface. During operation, the dust captured by the separation module 2 falls to the bottom of the first storage space 11 under gravity, and then automatically slides along the inclined surface of the first ramp 131 to the dust discharge port 13 and is discharged. Compared with the traditional horizontal dust collection box method, this solves the problem of dust retention caused by the horizontal bottom surface. In this embodiment, the inclined surface of the first ramp 131 eliminates the dead angle of accumulation between the traditional vertical wall and the dust discharge port 13, allowing the dust to slide down to the dust discharge port 13 under the combined action of gravity and airflow, thus avoiding equipment blockage caused by dust accumulation.

[0028] In an embodiment of the present invention, similarly, a second ramp 141 is provided at the drain outlet 14, and the second ramp 141 extends from the second storage space 12 to the drain outlet 14 at a certain angle. Please continue to refer to Figure 3 The second ramp 141 is located within the second storage space 12 of the dust removal and drainage module 1, near its bottom. The second ramp 141 extends towards the drain outlet 14 at a certain angle. It should be noted that the second ramp 141 can be a planar or curved surface, and its angle can be set according to the required water volume and flow rate. In this embodiment, the second ramp 141 utilizes gravity to allow water to naturally slide down to the drain outlet 14, preventing water from stagnating at the bottom of the second storage space 12 and improving the device's drainage efficiency.

[0029] Furthermore, to prevent water backflow, a drag-increasing chamfer 15 is also provided at the second slope 141. The drag-increasing chamfer 15 is used to prevent water backflow. Figure 3 As shown, the resistance-enhancing chamfer 15 is disposed within the drainage channel area of ​​the second slope 141. The resistance-enhancing chamfer 15 can be configured as a reverse-protruding or partially protruding inclined structure, presenting an angle facing the flow direction relative to the water flow direction. In this embodiment, by setting the resistance-enhancing chamfer 15, the unidirectional guiding characteristic of the second slope 141 is strengthened, ensuring that the water flows only downward and does not flow back upward, thereby improving the drainage stability of the device.

[0030] In an embodiment of the present invention, the separation module 2 is composed of several axial cyclone sub-units 21, and each axial cyclone sub-unit 21 has a dust discharge channel 211 at its bottom. Figure 4As shown, the separation module 2 consists of several axial cyclone sub-units 21 arranged side-by-side or in an array. Each axial cyclone sub-unit 21 independently undertakes the tasks of gas intake, diversion, and separation. During operation, the airflow passes axially, and under the action of wind force, dust is thrown against the pipe wall or falls below. Each axial cyclone sub-unit 21 has a dust discharge channel 211 at its bottom, and dust slides down by its own weight and is discharged through the dust discharge channel 211. In this embodiment, multiple axial cyclone sub-units 21 are connected in parallel to form the separation module 2, which makes the processed gas flow rate larger and the diversion more uniform; the dust discharge channel 211 ensures that dust is discharged from each individual axial cyclone sub-unit 21 in a timely manner, avoiding dust accumulation.

[0031] Furthermore, to eliminate dust accumulation in the gaps between adjacent axial cyclone sub-units 21, a dust discharge guide channel 212 is provided between each of the remaining adjacent axial cyclone sub-units 21, except for the topmost axial cyclone sub-unit 21. The outlet of the dust discharge guide channel 212 faces the dust discharge port 13. Please continue to refer to Figure 4 The topmost axial cyclone subunit 21, due to its higher position, accumulates less dust. Therefore, except for the topmost unit, each adjacent axial cyclone subunit 21 is connected by a dust discharge guide channel 212. This channel is a vertical flow-guiding structure connecting the lateral areas between two units. The dust discharge guide channel 212 can be in the form of a chute, pipe, etc., guiding the dust downwards for concentrated discharge. In this embodiment, the dust discharge guide channel 212 directs the dust from multiple dust discharge channels 211 to the bottom dust discharge port 13, such as... Figure 5 As shown, the device achieves automated gravity dust removal.

[0032] In an embodiment of the present invention, the hydrophobic module 3 is composed of a blade fixing frame 32 and a plurality of louvers 31 vertically mounted, with the louvers 31 and the blade fixing frame 32 spaced apart. Figure 2 and Figure 6 As shown, the hydrophobic module 3 is used to remove moisture from the gas. The blade holder 32 can be configured as a frame-like or grid-like support, serving to position and separate the blades, ensuring that each louver 31 is arranged at a set interval in the airflow channel. The louvers 31 are L-shaped and vertically mounted on the blade holder 32. It should be noted that the louvers 31 can be arranged in a staggered or straight manner to enhance the interception and separation of moisture. In this embodiment, when the gas passes through the hydrophobic module 3, water vapor is agglomerated into droplets due to collision and inertial deflection as it passes through the gaps between the louvers 31, adhering to the surface of the louvers 31. Subsequently, the water droplets slide naturally down the surface of the louvers 31 under the action of gravity and are guided to the drain outlet 14 at the bottom of the device for discharge, improving the drainage efficiency of the device.

[0033] In an embodiment of the present invention, the water supply module is further provided with a porous medium 33, which is installed at the bend of the louver 31. Please continue to refer to... Figure 6 Because the louvers 31 are L-shaped, the porous medium 33 is fixed at the bend of each louver 31. The porous medium 33 can be made of hydrophilic or absorbent materials, such as metal foam or fiber felt. In this embodiment, the bend is an area with strong airflow turbulence and where droplets easily adhere and accumulate. The porous medium 33 structure can absorb these droplets, preventing them from penetrating the louver 31 area with the airflow and improving the dehumidification effect of the device.

[0034] In embodiments of the invention, the thickness of the porous medium 33 is configured to be less than the spacing between adjacent louvers 31. For example... Figure 7 As shown, the long side of louver 31 is a, the short side is b, and the length can be adjusted according to actual needs. The thickness of louver 31 is d, and the thickness of porous medium 33 is H, the range of which can be [missing information]. The length is L, and its range can be... The pore radius of the porous medium 33 is r, which can range from 10 μm to 3 mm; the porosity of the pore structure can be 70% to 99%, and the porosity is the percentage of pore volume to the total volume of the porous material structure. The appropriate pore size and porosity of the porous medium 33 can be selected according to actual needs. In this embodiment, the thickness of the porous medium 33 is limited to avoid obstructing airflow, thus balancing the dehumidification performance and ventilation efficiency of the device.

[0035] In this embodiment, to ensure the structural stability of the porous medium 33, the porous medium 33 consists of a fixed framework and interconnected pores. The framework can be made of metal, polymer, or fiberglass, and its structure can be mesh-like, honeycomb-like, or foam-like. Numerous fine, interconnected pore channels are formed between the framework members, and these pores are spatially interconnected, allowing air to flow smoothly through the porous medium 33. In this embodiment, the fixed framework ensures that the porous medium 33 does not collapse, curl, or shift under airflow impact, thus guaranteeing the stability of the device.

[0036] In addition, such as Figure 8 As shown, the separation module 2 can be installed in multiple stages according to usage requirements, and different impeller parameters, guide angles, or filtration accuracies can be designed between each stage according to functional differences, forming a progressive separation effect. In this embodiment, multi-stage installation can form a progressively enhanced dust separation path, collecting particles sequentially from coarse to fine, ensuring the device's working efficiency even in specific operating environments.

[0037] Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to this invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
