Description

Technical Field

[0001] This invention relates to the field of deodorization and sterilization technology for garbage stations, specifically to an active, consumable-free deodorization and sterilization device for garbage stations. Background Technology

[0002] As a crucial node in the collection and transfer of urban domestic waste, the treatment of odorous gases and bacteria / viruses at waste stations has always been a key focus of the industry. Currently, commonly used deodorization and sterilization technologies at waste stations mainly include plant liquid spraying, activated carbon adsorption, and full-space ventilation and purification. Plant liquid spraying technology reduces the perceived intensity of odors by spraying chemical agents or plant extracts into the air, using masking or neutralization reactions. Activated carbon adsorption technology uses the physical adsorption of porous materials such as activated carbon to trap odor molecules in the pores of the material. Full-space ventilation and purification technology uses large fans to draw air from the station into a pipeline system equipped with ultraviolet photocatalysis or plasma generators for centralized treatment. These technologies have been applied to varying degrees in waste stations both domestically and internationally, providing basic means to solve the environmental pollution problems of waste stations.

[0003] While the aforementioned existing technologies have played a role in the field of deodorization and sterilization in waste stations, their common inherent flaw lies in the lack of proactive adaptation to dynamically changing pollution sources within the waste station. During the unloading, compression, and transfer processes, the odor-generating points in waste stations are not fixed but move randomly with changes in the location of waste piles, switching of unloading ports, and the flow of leachate. Existing deodorization devices mostly adopt a fixed-position installation method, and once the positions of their detection sensors and purification nozzles or exhaust vents are determined, they cannot be adjusted. When the odor-generating point is far from the fixed detection point, the sensor cannot capture concentration changes in time; when the odor-generating point is far from the fixed treatment point, the purification agent cannot effectively cover the polluted area, resulting in a significant reduction in deodorization and sterilization effects. To solve this problem, some solutions adopt a full-space coverage approach, that is, by increasing the power of the fan or increasing the amount of agent sprayed to expand the treatment range, but this leads to a sharp increase in energy consumption and a significant increase in operating costs, and cannot achieve precise, rapid, and low-energy proactive targeted treatment of randomly and dynamically changing odor-generating points within the waste station. Therefore, we propose an active, consumable-free deodorization and sterilization device for waste stations. Summary of the Invention

[0013] Preferably, the telescopic rod body is a hollow square rod structure, and the telescopic rod slides in conjunction with the bottom rectangular opening of the main cylinder.

[0019] This active, consumable-free deodorization and sterilization device for waste stations utilizes multiple independently adjustable detection devices within a custom detection matrix component. These devices allow for flexible adjustment of each odor sensor to its optimal detection position based on the actual shape and location of the waste pile. This overcomes the blind spots caused by changes in waste placement in traditional fixed sensors, enabling precise and proactive targeted treatment of dynamic pollution sources. Employing a steerable pneumatic focusing ion jet assembly, after the controller identifies the odor hotspot, the first and second motors drive the jet unit to rotate horizontally and adjust its pitch, ensuring the nozzle precisely points at the pollution source and jets a high-concentration ion stream. This represents a technological leap from passive, fixed-position treatment to dynamic, proactive jetting. Instead of requiring high-energy-consuming treatment across the entire waste station space, the purification energy is precisely targeted to the specific areas that require treatment, significantly reducing the overall operating energy consumption of the device while maintaining effective deodorization and sterilization.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-7 The present invention provides a technical solution;

[0030] An active, consumable-free deodorization and sterilization device for a waste station includes a support frame 1 and a controller 2 disposed on top of the support frame 1, with the controller 2 located at the center of the top of the support frame 1. The support frame 1 is located at the top of the interior of the waste station. The device also includes:

[0031] The custom detection matrix component consists of adjustable detection devices arranged in a three-row, four-column matrix. The adjustable detection devices consist of a main cylinder 3 and a telescopic rod 4. The top of the main cylinder 3 is rotatably engaged with the bottom of the support frame 1, and the telescopic rod 4 is slidably engaged and snapped inside the main cylinder 3.

[0032] The steerable pneumatic focusing ion jet assembly consists of two rows and three columns of rectangularly distributed ion jet deodorization devices. The ion jet deodorization devices and adjustable detection devices are arranged in a planar staggered manner and are all electrically connected to the controller 2. The controller 2 uses a PLC or embedded ARM processor to coordinate all detection sensor signals and jet actions. The custom detection matrix assembly adopts a matrix layout of 12 adjustable detection devices in three rows and four columns, covering the main stacking area of ​​the waste station. Each adjustable detection device can independently adjust its height and angle to achieve adaptive fitting to the surface of irregular waste piles. The steerable pneumatic focusing ion jet assembly adopts a rectangular layout of 6 ion jet deodorization devices in two rows and three columns, which are staggered with the detection devices to ensure that there is a jet unit covering each detection hot spot. This staggered layout of detection and jet allows the controller 2 to quickly match the nearest jet unit for targeted treatment of hot spots.

[0033] The ion jet deodorization device includes a first support 5, a second support 6, a low-temperature plasma emitter 7, an axial flow booster fan 8, and a third support 9. The first support 5 is located at the bottom of the support frame 1, and the second support 6 is located at the bottom of the first support 5, with the second support 6 having a horizontal rotational degree of freedom. The third support 9 is located inside the bottom end of the second support 6, with the second support 6 having a vertical rotational degree of freedom. The low-temperature plasma emitter 7 is fixedly connected to the inside of the second support 6. The axial flow booster fan 8 is located at the output end of the low-temperature plasma emitter 7. The first support 5 fixes the entire jetting unit to the bottom of the support frame 1. The second support 6 achieves 360° horizontal rotation under the drive of the first motor 10, and the third support 9 achieves pitch adjustment from -30° to +45° under the drive of the second motor 14. The dual degrees of freedom allow the ion jet deodorization device to be pointed to any position in space. The low-temperature plasma emitter 7 uses a dielectric barrier discharge structure to generate high-concentration plasma. The axial flow booster fan 8 is installed at its output end and is responsible for pressurizing and accelerating the ionized ion gas flow to form a high-speed jet with directional kinetic energy.

[0034] Furthermore, the outer side of the support frame 1 is a rectangular frame structure, and each of the four corners of the bottom of the support frame 1 is provided with a mounting block 22. The mounting block 22 is a right-angle plate structure, and the two vertical side walls of the mounting block 22 are detachably connected to the four corners of the top of the garbage station through matching bolts. The mounting blocks 22 at the four corners of the support frame 1 adopt a right-angle plate design, which can fit into the wall or steel beam structure at the four corners of the top of the garbage station. The detachable connection through matching bolts facilitates the overall disassembly during later maintenance. Since the lowest point of this device is left with sufficient operating space from the ground, the ceiling-mounted installation will not interfere with the entry and exit of garbage trucks and the operation of the compression equipment.

[0035] Furthermore, the support frame 1 is equipped with a welded main steel beam frame 19 inside. The main steel beam frame 19 is composed of two horizontal beams and three vertical beams welded perpendicularly and alternately. The horizontal beams are consistent with the long side of the support frame 1, and the vertical beams are consistent with the short side of the support frame 1. The controller 2 is detachably connected to the top of the main steel beam frame 19 through adapter screws. The main steel beam frame 19 adopts two horizontal beams and three vertical beams welded perpendicularly and alternately, which significantly improves the overall rigidity and torsional resistance of the support frame 1. The controller 2 is fixed at the top center of the main steel beam frame 19. This position makes the signal transmission distance between the controller 2 and all the detection devices and spraying devices below basically equal, which is conducive to ensuring the synchronization and reliability of communication. The detachable connection design facilitates the independent maintenance or replacement of the controller 2 without disassembling the entire support frame 1.

[0036] Furthermore, the main steel beam frame 19 is internally composed of rectangular openings arranged in three rows and four columns. A secondary steel beam frame 20 is welded inside each rectangular opening. The secondary steel beam frame 20 has a cross-shaped structure, and a universal ball bearing 21 is located at the center of its bottom. Each rectangular opening corresponds to the installation position of an adjustable detection device. The cross-shaped structure of the secondary steel beam frame 20 welded inside the rectangular opening enhances the structural strength of this area and provides a rotation fulcrum for the adjustable detection device. The universal ball bearing 21, as the ball head of a ball hinge, cooperates with the universal ball shell 27 at the top of the main cylinder 3 to form a universal rotation pair, enabling each adjustable detection device to independently achieve tilt adjustment in any direction. Operators can manually adjust the spatial orientation of each detection device, allowing the odor sensor 26 to be positioned flexibly instead of being fixed vertically downward, which would prevent detection in certain areas. This achieves the function of freely adjustable detection of the garbage dump monitoring points.

[0037] Furthermore, the main cylinder 3 is a hollow square cylinder structure, and the bottom opening of the main cylinder 3 is square. The top shaft end of the main cylinder 3 is provided with a universal ball shell 27, which is rotatably connected with the universal ball 21. The two opposite side walls of the main cylinder 3 are provided with a set of equal-distance adjustment holes 23, which are connected to the inside of the main cylinder 3. After the universal ball shell 27 and the universal ball 21 are engaged, the main cylinder 3 can swing in all directions relative to the support frame 1, so that the operator can flexibly adjust the pointing angle of each detection device to adapt to different garbage pile positions. The set of equal-distance adjustment holes 23 are arranged along the axial direction of the main cylinder 3 and cooperate with the spring button 25 to realize multi-level height adjustment, forming a reliable locking structure. The hollow design of the main cylinder 3 meets the requirements of lightweight technology.

[0038] Furthermore, the telescopic rod 4 has a hollow square rod structure, and it slides into the rectangular opening at the bottom of the main cylinder 3. A slider 24, which is square in shape, is located at the top shaft end of the telescopic rod 4. The slider 24 slides into the interior of the main cylinder 3, and spring buttons 25 are located inside the two opposite side walls of the slider 24. These spring buttons 25 have a degree of freedom in their sliding motion and engage with the adjustment hole 23. An odor sensor 26 is located at the bottom shaft end of the telescopic rod 4, outside the bottom opening shaft end of the main cylinder 3. The hollow square rod structure of the telescopic rod 4 reduces overall weight while maintaining strength, facilitating manual adjustment. The square shape of the slider 24 and the square cross-section of the inner wall of the main cylinder 3 form a sliding guide. To ensure the telescopic rod 4 operates smoothly and without rotation during extension and retraction, the spring button 25 has a built-in compression spring that normally pops outward. When height adjustment is needed, the operator simultaneously presses the spring buttons 25 on the two opposite sidewalls at the top of the telescopic rod 4, causing them to retract and disengage from the adjustment hole 23. At this point, the telescopic rod 4 can be freely pushed and pulled. Once the target position is reached, the button is released, and the spring button 25 automatically engages with the corresponding height adjustment hole 23, achieving rapid locking. The odor sensor 26 can be a MEMS-grade ammonia sensor or a hydrogen sulfide sensor, ensuring it is directly exposed to the air above the garbage pile. By adjusting the extension length of the telescopic rod 4, the odor sensor 26 can be positioned at the optimal detection height at the top of the garbage pile, thereby obtaining the most accurate odor concentration signal.

[0039] Furthermore, the first bracket 5 is a U-shaped bent plate structure, and the first bracket 5 is located at the bottom where the crossbeam and longitudinal beam of the third bracket 9 intersect perpendicularly. The two opposite sides of the top of the first bracket 5 are detachably connected to the bottom of the third bracket 9 by adapter screws. The first motor 10 is fixedly connected inside the first bracket 5. The bottom of the first motor 10 is the output shaft end. The first bracket 5 adopts a U-shaped bent plate structure with its opening facing upward, forming a space to accommodate the first motor 10 and also protecting the motor. The first bracket 5 is installed at the bottom of the intersection of the crossbeam and longitudinal beam of the main steel beam frame 19, using the most stable intersection point as support to reduce vibration transmission. The first motor 10 is fixed inside the first bracket 5, and its output shaft extends downward, driving the second bracket 6 to rotate horizontally through a coupling. The first motor 10 is electrically connected to the controller 2 and receives the horizontal steering command issued by the controller 2 to achieve millisecond-level response.

[0040] Furthermore, the second bracket 6 is an inverted U-shaped bent plate structure, and a connecting shaft 11 is provided at the top of the second bracket 6. The connecting shaft 11 is connected to the output shaft at the bottom of the first motor 10 through a coupling. A mounting plate 12 is provided on the side wall of the second bracket 6. The mounting plate 12 is a rectangular plate structure, and a cylindrical section on the side wall of the mounting plate 12 connects to the side wall of the second bracket 6. A mating hole 13 is provided on the side wall of the second bracket 6, located away from the controller 2, and the mating hole 13 is concentric with the cylindrical section on the side wall of the mounting plate 12. The connecting shaft 11 serves as the connection between the first motor 10 and the second bracket 6. The power transmission components are connected by a coupling to compensate for minor installation coaxiality errors. The mounting plate 12 is fixed to the side wall of the second bracket 6. Its cylindrical structure is used to accommodate the output shaft of the second motor 14 and acts as a bearing seat. The mating hole 13 is opened on the side wall of the second bracket 6 away from the controller 2, and is concentric with the cylindrical side wall of the mounting plate 12, so that the connecting shafts on both sides of the third bracket 9 can rotate coaxially, ensuring the stability of pitch adjustment. The first motor 10 and the second motor 14 are responsible for horizontal rotation and pitch adjustment respectively, forming a complete two-dimensional steering gimbal structure.

[0041] Furthermore, the third bracket 9 has a U-shaped bent plate structure, and a second motor 14 is provided on the side wall of the third bracket 9. The second motor 14 is fixedly connected to the mounting plate 12, and the output shaft of the second motor 14 is located inside the cylindrical side wall of the mounting plate 12. The shaft end of the output shaft of the second motor 14 is welded to the side wall of the third bracket 9, and a connecting shaft is provided on the side wall of the third bracket 9 opposite to the second motor 14, which is rotatably engaged with the mating hole 13. The U-shaped bent plate structure of the third bracket 9 forms a space to accommodate the low-temperature plasma emitter 7 and the axial flow booster fan 8. The second motor 14, which provides protection and support, is fixed to the mounting plate 12. Its output shaft passes through the cylindrical tube and is welded to one side wall of the third bracket 9, directly transmitting the motor torque to the third bracket 9. The connecting shaft on the other side wall of the third bracket 9 is inserted into the mating hole 13 and rotates freely, forming a driven support. This ensures both the driving force for pitch adjustment and the rigidity of the large-span bracket. The second motor 14 receives instructions from the controller 2 to perform precise angle control, which, together with the horizontal rotation of the first motor 10, allows the nozzle 17 to be aimed at any hot spot in the space.

[0042] Furthermore, the low-temperature plasma emitter 7 has a dustproof net 18 on its side wall, and a first flange 15 on its side wall, located away from the dustproof net 18. The axial flow booster fan 8 has a second flange 16 on the side corresponding to the low-temperature plasma emitter 7, which is bolted to the first flange 15. The axial flow booster fan 8 has a nozzle 17 at its outlet, which is a Laval tube structure. The dustproof net 18 is installed on the inlet side of the low-temperature plasma emitter 7 to filter large particulate dust from the air in the waste station. To prevent dust accumulation on the electrode surface from reducing discharge efficiency, the first flange 15 and the second flange 16 are connected by bolts to rigidly fix the low-temperature plasma emitter 7 to the axial flow booster fan 8. The flange connection method has good sealing performance and is easy to disassemble and assemble. The axial flow booster fan 8 is located at the output end of the low-temperature plasma emitter 7. Ambient air enters the low-temperature plasma emitter 7 after being filtered by the dustproof net 18. It is ionized in the DBD electrode area to generate high-concentration plasma, which is then drawn in by the axial flow booster fan 8 and pressurized and accelerated to form a directional high-speed airflow, which is finally ejected through the nozzle 17.

[0043] The Laval tube structure allows the airflow to accelerate to sonic speed in the contraction section and further accelerate to supersonic speed in the expansion section, thereby forming a high-speed ion jet at the nozzle 17 outlet. The pressurized and accelerated airflow organization ensures that the plasma has sufficient residence time in the discharge zone, which not only guarantees ionization efficiency, but also utilizes the pressurization capacity of the axial flow booster fan 8 and the aerodynamic acceleration characteristics of the Laval tube to obtain a high-speed jet that meets the requirements of long-distance jetting, realizing active targeted deodorization and sterilization of any hot spot area in the waste station, and achieving active deodorization and sterilization without consumables.

[0044] Working principle: Install the active, consumable-free deodorization and sterilization device for the garbage station according to the diagram. The entire device is installed at the top inside the garbage station, with sufficient operating space at its lowest point from the ground to ensure that it does not interfere with the entry and exit of garbage trucks and the normal operation of the compression equipment.

[0045] Before the device is put into operation, each adjustable detection device in the custom detection matrix component needs to be independently adjusted according to the actual shape and position of the pre-piled garbage in the garbage station. When the height of the odor sensor 26 needs to be adjusted, the operator simultaneously presses the spring buttons 25 on the two opposite side walls of the top of the telescopic rod 4, causing the spring buttons 25 to retract and disengage from the current adjustment hole 23. Then, the telescopic rod 4 is pushed and pulled to the desired position. After releasing the buttons, the spring buttons 25 automatically engage with the corresponding height adjustment hole 23, achieving quick locking. When there is a horizontal deviation between the relative position of the odor sensor 26 and the top of the garbage pile, the operator can rotate the main cylinder 3 as a whole. Using the universal joint formed by the universal ball shell 27 at the top of the main cylinder 3 and the universal ball bearing 21 at the bottom of the secondary steel beam frame 20, the adjustable detection device can be tilted in any direction, thereby accurately aligning the odor sensor 26 with the detection point at the top of the garbage pile. After the adjustment is completed, each odor sensor 26 is in its optimal detection position.

[0046] When the device enters standby mode, all ion jet deodorization devices in the steerable pneumatic focusing ion jet assembly are in the zero position, and the low-temperature plasma emitter 7 and axial flow booster fan 8 are in standby mode.

[0047] When the device starts running, the controller 2 reads the odor concentration signal and its position coordinates uploaded by each odor sensor 26 in real time. Once one or more odor sensors 26 detect a sudden increase in concentration, the controller 2 selects the ion jet deodorization device closest to the hot spot and with an unobstructed jet path as the target jet unit according to the built-in sensor and jet unit position mapping table. Then, the controller 2 sends a command to the target jet unit to drive the first motor 10 to start. The first motor 10 drives the second bracket 6 to rotate horizontally through the connecting shaft 11 to achieve precise horizontal angle alignment. At the same time, it drives the second motor 14 to start. The second motor 14 drives the third bracket 9 to adjust the vertical pitch angle so that the nozzle 17 points to the center of the hot spot in the vertical plane. The horizontal rotation and pitch adjustment work together to make the nozzle 17 accurately aligned with the odor hot spot position in three-dimensional space.

[0048] After alignment, controller 2 starts the low-temperature plasma emitter 7 and axial flow booster fan 8. Ambient air enters the low-temperature plasma emitter 7 after being filtered by dust filter 18. Under the action of dielectric barrier discharge structure, it is ionized to generate high-concentration plasma. Subsequently, the ion gas flow is drawn in by axial flow booster fan 8 and pressurized and accelerated. After being accelerated by nozzle 17 of Laval tube structure, it forms a high-speed ion jet, which is instantly shot towards the detection point. The high-energy electrons and active free radicals in the jet react with malodorous gas molecules such as ammonia and hydrogen sulfide, as well as bacteria and viruses in aerosols, to undergo oxidation and decomposition reactions, converting them into harmless substances such as carbon dioxide and water, thus achieving the function of deodorization and sterilization.

[0049] As unloading and compression operations proceed within the waste station, odor hotspots may shift. Controller 2 continuously samples and recalculates the hotspot coordinates at preset intervals, dynamically adjusting the rotation angles of the first motor 10 and the second motor 14 of the target injection unit. This ensures that nozzle 17 always follows the hotspot's movement trajectory and injects until the hotspot concentration drops below a safe threshold. After injection stops, controller 2 resets the steerable pneumatic focusing ion injection component to zero, and the system re-enters standby mode, awaiting the next trigger.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
