Description

Technical Field

[0001] This utility model belongs to the field of air purification technology, and more specifically, it relates to an integrated VOCs adsorption and purification device for industrial use. Background Technology

[0002] In modern industrial production, many industries such as chemicals, coating, printing, and electronics inevitably emit large amounts of volatile organic compounds (VOCs) during production. These VOCs not only cause serious air pollution, serving as important precursors to atmospheric problems such as photochemical smog and ozone pollution, but also pose significant health risks, potentially leading to respiratory diseases, nervous system damage, and even cancer. Therefore, the effective treatment of VOCs emitted from industry has become a critical issue urgently needing to be addressed in the field of environmental protection.

[0003] Currently, the main technologies for treating industrial VOCs include absorption, combustion, catalytic combustion, and adsorption. Among these, adsorption is widely used due to its advantages such as high treatment efficiency, simple operation, and recyclability. However, existing VOCs adsorption purification equipment still has some shortcomings in practical applications. For example, traditional adsorption equipment is often structurally complex, occupies a large area, and has high installation and maintenance costs; moreover, the coordination between functional units is poor, leading to unstable purification efficiency and difficulty in meeting increasingly stringent environmental emission standards. Utility Model Content

[0004] To overcome these shortcomings in the prior art, this utility model provides an integrated industrial VOCs adsorption and purification device that is compact in structure, highly efficient in purification, stable in operation, and easy to maintain.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide an integrated VOCs adsorption and purification device for industrial use, including a housing, wherein the housing is provided with a filter chamber, a buffer chamber and an exhaust chamber from bottom to top; An air inlet pipe is provided on the outside of the filter chamber, and a filter unit is provided inside the filter chamber. The filter unit has a filter cavity, and the air inlet pipe is connected to the filter cavity. The bottom of the buffer chamber is provided with an air inlet that connects to the filter chamber, and the top of the buffer chamber is provided with an air outlet that connects to the exhaust chamber. An exhaust pipe is installed on the outside of the exhaust chamber, and an exhaust fan is installed inside the exhaust chamber. The air inlet of the exhaust fan is connected to the air outlet, and the exhaust outlet of the exhaust fan is connected to the exhaust pipe.

[0006] In one possible implementation, the filtration unit includes two longitudinal filter plates symmetrically arranged in the filtration chamber. The upper ends of the longitudinal filter plates are sealed to the top of the filtration chamber, and the lower ends of the longitudinal filter plates are sealed to the bottom of the filtration chamber. The filtration cavity is formed between the two longitudinal filter plates and the top and bottom of the filtration chamber. The exhaust end of the air inlet pipe is connected to the outer wall of the filtration chamber.

[0007] In one possible implementation, the filter unit includes a U-shaped filter plate, the open side of which is sealed to the inner wall of the filter chamber, the upper end of which is sealed to the top of the filter chamber, and the lower end of which is sealed to the bottom of the filter chamber. The filter cavity is formed between the U-shaped filter plate, the inner wall of the filter chamber, and the top and bottom of the filter chamber. The exhaust end of the air inlet pipe is connected to the outer wall of the filter chamber.

[0008] In one possible implementation, the filtration unit includes a filter cylinder, the upper end of which is sealed to the top of the filter chamber, the lower end of which is sealed to the bottom of the filter chamber, the interior of which forms the filtration cavity, and the exhaust end of the air inlet pipe extends into the interior of the filter cylinder.

[0009] In one possible implementation, the exhaust end of the air inlet duct is provided with a primary filter layer.

[0010] In one possible implementation, the exhaust end of the air inlet duct is opened longitudinally and its length is greater than half the length of the filter chamber.

[0011] In one possible implementation, the air inlet is formed on the outer periphery of the filter unit, and the air outlet is formed in the middle of the top of the buffer chamber.

[0012] In one possible implementation, a gas collecting hood is provided in the buffer chamber, with the lower end of the gas collecting hood sealed to the bottom of the buffer chamber and the upper end of the gas collecting hood sealed to the top of the buffer chamber. The gas collecting hood is used to guide gas from the air inlet into the air outlet.

[0013] In one possible implementation, the inner wall of the exhaust chamber is provided with a vibration damping layer, and the inner wall of the vibration damping layer is provided with multiple concave and convex structures.

[0014] In one possible implementation, the bottom of the box is provided with several casters.

[0015] The beneficial effects of the integrated VOCs adsorption and purification equipment for industrial use provided by this utility model are as follows: Compared with the prior art, the equipment arranges the filter chamber, buffer chamber, and exhaust chamber sequentially from bottom to top within the housing. This layered spatial layout design makes full use of the vertical space of the housing, avoiding the large footprint problem caused by the dispersed arrangement of functional units in traditional equipment. Each functional chamber forms a compact whole within the housing, greatly reducing the overall size of the equipment and enabling it to adapt to different installation site conditions, especially in space-constrained industrial production environments. The equipment adopts a layered structure, with the filter chamber, buffer chamber, and exhaust chamber independently located within the housing, making maintenance and repair of each functional chamber more convenient. When a functional chamber malfunctions or requires maintenance, only that functional chamber needs to be operated, without the need for large-scale disassembly of the equipment, reducing maintenance difficulty and workload. The filter unit within the filter chamber has an independent filter cavity and is connected to the air inlet pipe. When the filtration effect is lost due to the trapping of impurities during use, the entire filter unit can be replaced. The process is simple and quick, requiring no complex operations or professional technicians, effectively reducing maintenance costs and time, and improving equipment maintainability.

[0016] An air inlet duct is installed on the outside of the filter chamber. The internal filter unit has a filter cavity connected to the air inlet duct, which can filter VOCs-containing waste gas, removing dust, particulate matter, and other impurities to prevent them from affecting the subsequent adsorption process and clogging the adsorbent. This ensures that the adsorbent maintains a high adsorption efficiency, laying the foundation for efficient VOCs purification. An air inlet connected to the filter chamber is located at the bottom of the buffer chamber, and an air outlet connected to the exhaust chamber is located at the top. This buffers and evenly distributes the airflow entering from the filter chamber, ensuring smooth airflow and avoiding violent fluctuations and local turbulence. The airflow enters the exhaust chamber evenly through the outlet. Waste gas enters the filter chamber through the air inlet duct for pretreatment. After the airflow distribution is optimized in the buffer chamber, it is discharged by the exhaust fan in the exhaust chamber. Smooth connections between the functional chambers reduce internal airflow resistance and energy loss. Stable airflow ensures stable operation of various parameters, such as airflow rate and pressure, allowing the equipment to operate continuously and stably, ensuring reliable purification results. Meanwhile, the exhaust fan in the exhaust room can provide stable power for airflow. Reasonable control of its operating parameters can maintain a suitable negative pressure state inside the equipment, avoid fluctuations in purification efficiency due to unstable airflow, and further enhance operational stability.

[0023] Please see Figure 1The present invention provides an integrated industrial VOCs adsorption and purification device. The integrated industrial VOCs adsorption and purification device includes a housing, which, from bottom to top, comprises a filter chamber 1, a buffer chamber 2, and an exhaust chamber 3. An air inlet pipe 4 is provided on the outside of the filter chamber 1, and a filter unit 5 is provided inside the filter chamber 1. The filter unit 5 has a filter cavity 14, and the air inlet pipe 4 connects to the filter cavity 14. An air inlet 6 connecting to the filter chamber 1 is provided at the bottom of the buffer chamber 2, and an air outlet 7 connecting to the exhaust chamber 3 is provided at the top of the buffer chamber 2. An exhaust pipe 8 is provided on the outside of the exhaust chamber 3, and an exhaust fan 9 is provided inside the exhaust chamber 3. The air inlet of the exhaust fan 9 is connected to the air outlet 7, and the exhaust outlet of the exhaust fan 9 is connected to the exhaust pipe 8.

[0024] The industrial VOCs adsorption integrated purification equipment provided by this utility model, compared with the prior art, arranges the filter chamber 1, buffer chamber 2, and exhaust chamber 3 sequentially from bottom to top within the housing. This layered spatial layout design makes full use of the vertical space of the housing, avoiding the large footprint problem caused by the dispersed arrangement of functional units in traditional equipment. Each functional chamber forms a compact whole within the housing, greatly reducing the overall size of the equipment and making it adaptable to different installation site conditions, especially in space-constrained industrial production environments. The equipment adopts a layered structure, with the filter chamber 1, buffer chamber 2, and exhaust chamber 3 independently set within the housing, making maintenance and repair of each functional chamber more convenient. When a functional chamber malfunctions or requires maintenance, only that functional chamber needs to be operated, without the need for large-scale disassembly of the equipment, reducing maintenance difficulty and workload. The filter unit 5 in the filter chamber 1 has an independent filter cavity 14 and is connected to the air inlet pipe 4. When it loses its filtering effect due to the trapping of impurities during use, the filter unit 5 can be replaced as a whole. The process is simple and quick, requiring no complex operations or professional technicians, effectively reducing maintenance costs and time, and improving equipment maintainability.

[0025] An air inlet duct 4 is installed on the outside of the filter chamber 1, and the internal filter unit 5 has a filter cavity 14 connected to the air inlet duct 4. It can filter VOCs-containing waste gas, remove dust, particulate matter and other impurities, and prevent them from affecting the subsequent adsorption process and clogging the adsorbent. This ensures that the adsorbent always maintains a high adsorption efficiency, laying the foundation for efficient VOCs purification. The bottom of the buffer chamber 2 is equipped with an air inlet 6 connected to the filter chamber 1, and the top is equipped with an air outlet 7 connected to the exhaust chamber 3. It can buffer and evenly distribute the airflow entering from the filter chamber 1, so that the airflow flows smoothly and avoids violent fluctuations and local turbulence. The airflow enters the exhaust chamber 3 evenly through the air outlet 7. The waste gas enters the filter chamber 1 for pretreatment through the air inlet duct 4. After the airflow distribution is optimized by the buffer chamber 2, it is discharged by the exhaust fan 9 in the exhaust chamber 3. The smooth connection of each functional chamber reduces the internal resistance of the airflow and energy loss. The stable airflow ensures the stability of various parameters during operation, such as airflow rate and pressure, so that the equipment can operate continuously and stably and ensure reliable purification effect. Meanwhile, the exhaust fan 9 in the exhaust chamber 3 can provide stable power for airflow. Reasonable control of its operating parameters can maintain a suitable negative pressure state inside the equipment, avoid fluctuations in purification efficiency due to unstable airflow power, and further enhance operational stability.

[0026] Please see Figure 2 The filter unit 5 includes two longitudinal filter plates 501, which are symmetrically arranged in the filter chamber 1. The upper end of each longitudinal filter plate 501 is sealed to the top of the filter chamber 1, and the lower end of each longitudinal filter plate 501 is sealed to the bottom of the filter chamber 1. The two longitudinal filter plates 501 and the top and bottom of the filter chamber 1 form a filter cavity 14. The exhaust end of the air inlet pipe 4 is connected to the outer wall of the filter chamber 1. The symmetrically arranged longitudinal filter plates 501 increase the filtration area, which can efficiently intercept dust, particulate matter and other impurities in the exhaust gas, improve the pretreatment effect, and prevent impurities from clogging the subsequent adsorption unit. The upper and lower ends of the longitudinal filter plate 501 are sealed to the filter chamber 1, which prevents unfiltered exhaust gas from bypassing the filter plate and directly entering the buffer chamber 2, ensuring that all exhaust gas is treated by the filter inner cavity 14, thus ensuring the integrity and effectiveness of pretreatment. At the same time, the symmetrical structure makes the airflow more evenly distributed in the filter inner cavity 14, reducing airflow resistance and local turbulence, optimizing the airflow path of the entire equipment, and the longitudinal arrangement makes full use of the vertical space of the filter chamber 1 without increasing the equipment's floor space, which helps the equipment maintain its compact structure.

[0027] Please see Figure 3The filter unit 5 includes a U-shaped filter plate 502. The open side of the U-shaped filter plate 502 is sealed to the inner wall of the filter chamber 1. The upper end of the U-shaped filter plate 502 is sealed to the top of the filter chamber 1, and the lower end of the U-shaped filter plate 502 is sealed to the bottom of the filter chamber 1. The U-shaped filter plate 502, the inner wall of the filter chamber 1, and the top and bottom of the filter chamber 1 form a filter cavity 14. The exhaust end of the air inlet pipe 4 is connected to the outer wall of the filter chamber 1. The U-shaped structure of the U-shaped filter plate 502 significantly expands the filtration area through its bending shape, improving impurity interception efficiency by more than 30% compared to a flat filter plate. This effectively removes dust, particulate matter, and other impurities from the exhaust gas, providing cleaner airflow conditions for subsequent adsorption units. The sealed connection design ensures that the exhaust gas completely flows through the filter cavity 14, making the pretreatment process more thorough. The U-shaped filter plate 502, fitted to the inner wall of the filter chamber 1, makes full use of the corner space. Without increasing the lateral dimensions of the equipment, the volume ratio of the filter unit 5 is increased to more than half that of the filter chamber 1, enhancing the filtration effect while maintaining the overall compactness of the equipment. At the same time, the U-shaped structure guides the airflow in a spiral shape through the filter cavity 14, reducing airflow resistance and turbulence, allowing the airflow to enter the buffer chamber 2 evenly, laying a stable foundation for the subsequent purification process.

[0028] Please see Figure 4 The filter unit 5 includes a filter cylinder 503. The upper end of the filter cylinder 503 is sealed to the top of the filter chamber 1, and the lower end of the filter cylinder 503 is sealed to the bottom of the filter chamber 1. The interior of the filter cylinder 503 forms a filter cavity 14, and the exhaust end of the air inlet pipe 4 passes through the interior of the filter cylinder 503. The cylindrical structure of the filter cylinder 503 can uniformly intercept dust, particulate matter, and other impurities in the exhaust gas at 360°, significantly increasing the filtration area compared to a planar filter plate, improving pretreatment efficiency, and effectively preventing impurities from clogging subsequent adsorption units. The sealed design at the upper and lower ends ensures that the exhaust gas can only pass through the filter cavity 14 inside the filter cylinder 503, eliminating the bypass phenomenon of unfiltered gas and ensuring the thoroughness of pretreatment. The cylindrical structure makes the airflow radially and uniformly distributed in the filter cavity 14, reducing airflow resistance and turbulence, and optimizing the overall airflow stability of the equipment. Meanwhile, the filter cartridge 503 is installed longitudinally inside the filter chamber 1, making full use of the vertical space without occupying additional horizontal area, further enhancing the compact structure of the equipment. The cylindrical structure also facilitates standardized production and replacement maintenance, reducing equipment operation and maintenance costs.

[0029] Furthermore, a primary filter layer 10 is installed at the exhaust end of the air inlet duct 4, which can preliminarily purify the exhaust gas entering the filter unit 5, intercepting larger dust particles, particulate matter, and other impurities in the exhaust gas in advance, effectively reducing the load on the subsequent filter unit 5 and extending the service life of the filter unit 5. The primary filter layer 10 can filter out large particulate impurities, allowing the filter unit 5 to focus on processing fine particles and improving the overall filtration efficiency. At the same time, the primary filter layer 10 has a simple structure and is easy to replace. It can be disassembled, cleaned, or replaced separately, reducing equipment maintenance costs and difficulty. It can also prevent large particulate impurities from accumulating in the filter chamber 1, reducing the risk of internal blockage, ensuring unobstructed airflow, and maintaining stable equipment operation.

[0030] Specifically, the exhaust end of the air inlet duct 4 is longitudinally opened, and its length is greater than half the length of the filter chamber 1. This longitudinal, elongated opening can evenly guide the exhaust gas along the height direction of the filter chamber 1, avoiding the airflow segregation phenomenon caused by traditional single-point air intake. This makes the exhaust gas more evenly distributed in the filter cavity 14, improving the utilization rate of the filter unit 5. The design of the exhaust end of the air inlet duct 4 being longer than half the length of the filter chamber 1 expands the coverage area of ​​the air inlet 6 into a larger longitudinal space of the filter chamber 1. The initial velocity of the airflow entering the filter chamber 1 will be reduced, reducing the impact of high-speed airflow on the filter unit 5. At the same time, it prolongs the contact time between the exhaust gas and the filter material, allowing dust, particulate matter, and other impurities to be more fully intercepted. In addition, the longitudinal opening layout matches the vertical spatial structure of the filter chamber 1, avoiding the additional occupation of lateral space and ensuring the overall structure of the equipment is compact. Furthermore, the airflow guiding effect of the elongated opening can reduce intake turbulence, laying the foundation for the uniformization of airflow in the subsequent buffer chamber 2, and further improving the operational stability of the equipment.

[0031] Specifically, the air inlet 6 is shaped to fit the outer periphery of the filter unit 5, and the air outlet 7 is located in the middle of the top of the buffer chamber 2. The shaped air inlet 6 closely conforms to the contour of the filter unit 5, allowing exhaust gas to evenly penetrate into the filter cavity 14 from the outer periphery of the filter unit 5, preventing concentrated airflow from scouring localized filtration areas. Testing has shown that this improves the uniformity of airflow distribution on the surface of the filter unit 5, reducing filtration blind spots caused by uneven airflow. The air outlet 7, located in the middle of the top of the buffer chamber 2, utilizes fluid dynamics principles to guide the airflow into a symmetrical diffusion flow field within the buffer chamber 2. When the air is discharged through the top center, the turbulence intensity is significantly reduced compared to edge outlets. This layout allows the buffer chamber 2 to function as both an airflow buffer and a secondary flow equalization unit, providing stable and uniform airflow conditions for the subsequent exhaust chamber 3. Simultaneously, the central air outlet 7 is axially aligned with the air inlet of the exhaust fan 9 in the exhaust chamber 3, reducing energy loss during airflow turning and improving the overall operating efficiency of the equipment.

[0032] Preferably, a gas collecting hood 11 is installed inside the buffer chamber 2. The lower end of the gas collecting hood 11 is sealed to the bottom of the buffer chamber 2, and the upper end of the gas collecting hood 11 is sealed to the top of the buffer chamber 2. The gas collecting hood 11 is used to guide gas from the inlet 6 into the outlet 7. The gas collecting hood 11 can constrain and guide the airflow entering the buffer chamber 2 from the filter chamber 1, preventing the airflow from spreading disorderly in the buffer chamber 2, promoting the formation of a stable flow path for the gas, reducing turbulence and eddies, and thus making the airflow distribution in the buffer chamber 2 more uniform. At the same time, the guiding effect of the gas collecting hood 11 can reduce the energy loss of the airflow in the buffer chamber 2, ensuring that the airflow enters the exhaust chamber 3 with a more stable pressure and flow rate, which is beneficial to the stable operation of the exhaust fan 9 and enhances the overall operational stability of the equipment. In addition, the sealed connection design of the gas collecting hood 11 ensures that all gas flows through the path it guides, avoiding gas leakage or bypass, and ensuring the integrity and effectiveness of the function of the buffer chamber 2.

[0033] Preferably, the inner wall of the exhaust chamber 3 is provided with a vibration damping layer 12, and the inner wall of the vibration damping layer 12 has multiple concave and convex structures. The vibration damping layer 12 is made of elastic damping material, which can absorb the mechanical vibration generated by the exhaust fan 9 during operation, reduce the vibration energy transmitted to the housing, reduce the overall vibration noise of the equipment, and at the same time avoid the problem of component loosening caused by long-term vibration, thus extending the service life of the equipment. The concave and convex structures of the inner wall of the vibration damping layer 12, such as honeycomb or wave-shaped, on the one hand, disrupt the airflow boundary layer by increasing the surface roughness, thereby reducing the turbulence intensity of the airflow in the exhaust chamber 3 and reducing the aerodynamic noise generated by the friction between the airflow and the inner wall. On the other hand, the micro-cavities formed by the concave and convex structures can reflect and dissipate sound waves, thereby reducing the overall noise level of the equipment. In addition, the concave and convex structures do not affect the cross-sectional area of ​​the airflow channel of the exhaust chamber 3, ensuring that the exhaust efficiency of the exhaust fan 9 is not affected while achieving noise reduction and vibration reduction, maintaining the stable exhaust performance of the equipment. Moreover, this structure design is simple, easy to process and manufacture, and easy to maintain and replace later.

[0034] In addition, the bottom of the enclosure is equipped with several casters 13. These casters 13 are made of high-strength polyurethane, ensuring the stability of the equipment in industrial environments while also possessing wear-resistant and anti-slip properties, allowing for use on rough surfaces or slopes. This design frees the equipment from fixed installation limitations, facilitating layout adjustments according to production processes, and is particularly suitable for multi-station switching production lines, reducing space utilization issues caused by fixed equipment. The casters 13 are equipped with a braking locking device to ensure the stability of the equipment during operation and prevent loose casters from affecting the internal airflow path. Furthermore, the casters 13 raise the bottom of the enclosure, preventing water stains and dust accumulation from affecting equipment operation and extending the service life of the enclosure's bottom.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
