Description

Technical Field

[0001] This utility model relates to the field of adsorbent cooling technology, and in particular to a VOC adsorbent discharge cooling device. Background Technology

[0002] Volatile organic compounds (VOCs) are one of the important sources of air pollution. In industrial production, adsorbents (such as activated carbon and molecular sieves) are often used to adsorb and enrich VOCs in waste gas. After the adsorbent is saturated, it needs to be desorbed and regenerated. However, the temperature of the adsorbent after high-temperature desorption is extremely high. It must be effectively cooled before it can be put back into the adsorption process. Otherwise, it will not only affect the adsorption efficiency, but may also pose safety hazards.

[0003] In the prior art, there are various cooling devices for powdery and granular materials; for example, Chinese Patent Publication No. 202020937934.9 discloses "a cooling device for the discharge of an activation furnace for the production of gas adsorbents"; by setting a first motor in the material distribution mechanism to drive the spiral feeding rod to rotate, the adsorbent is evenly pushed into four Z-shaped guide tubes. The Z-shaped guide tubes increase the heat exchange area and moving distance of the adsorbent, making the cooling more uniform and the cooling effect better. At the same time, the material distribution mechanism allows the gas adsorbent to be cooled in a sealed environment.

[0004] The aforementioned comparative documents employ a rotating screw feeder to disperse the adsorbent, followed by air cooling or forced air cooling. However, due to the structural design of the screw feeder, the degree of dispersion of the adsorbent is limited, failing to ensure sufficient dispersion and contact with the cooling medium, resulting in poor cooling performance. Although this technology shortens the cooling time compared to natural cooling, the overall cooling efficiency is still not ideal, making it difficult to meet the practical needs of rapid cooling of batches of VOC adsorbents. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a VOC adsorbent discharge cooling device, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A VOC adsorbent discharge cooling device includes a cooling box, a cooling component, a collection component, a filter component, and a support component. The cooling component includes a partition fixedly installed inside the cooling box. A cooling pipe is fixedly installed inside the partition, with one end of the cooling pipe penetrating the interior of the cooling box. A feed hopper is fixedly installed at one end of the cooling pipe. A water inlet pipe is fixedly installed at the top of the cooling box, and a sealing cover is movably installed inside the water inlet pipe. A reflux pump is fixedly installed on the left side of the cooling box. A reflux pump is fixedly installed between the reflux pump and the cooling box. Four guide plates are fixedly installed inside the cooling box, and a third connecting pipe is fixedly installed between every two guide plates. A third connecting pipe is fixedly installed between the reflux pump and the guide plates. A discharge port is fixedly installed at the bottom of the cooling box. A cavity is provided inside the guide plates. A cavity is opened inside the cooling box, and the cavity is fixedly connected to the cavity inside the uppermost guide plate. A water outlet pipe is fixedly installed on the right side of the cooling box.

[0007] Furthermore, the collecting assembly includes a limiting plate fixedly installed on the back of the discharge port, a connecting pipe movably installed inside the limiting plate, a rotating block hinged to the back of the connecting pipe, a collecting box fixedly installed on the front of the connecting pipe, four support columns fixedly installed at the bottom of the collecting box, and casters fixedly installed at the bottom of each of the four support columns.

[0008] Furthermore, the filter assembly includes an air duct fixedly installed on the left side of the cooling box, a mounting base fixedly installed inside the air duct, an exhaust fan fixedly installed on the top of the mounting base, an activated carbon filter fixedly installed inside the cooling box, and a protective net fixedly installed inside the air duct.

[0009] Furthermore, the support assembly includes four support plates fixedly installed at the bottom of the cooling box, and a fixing plate is fixedly installed between every two support plates. A reinforcing rib is fixedly installed at the angle between the support plate and the fixing plate, and the outer surface of the reinforcing rib is triangular.

[0010] Furthermore, the feed hopper and cooling pipe are arranged in pairs, with a total of six sets fixed inside the cooling box.

[0011] Furthermore, a push rod is fixedly installed on the front of the collection box, and the outer surface of the push rod is L-shaped.

[0012] Compared with existing technologies, the advantages of this utility model are: 1. Through the distributed design of six sets of feed hoppers and cooling pipes arranged in pairs, combined with the heat exchange channel formed by the guide plate and the third connecting pipe inside the cooling box, the contact area between the VOC adsorbent and the cooling medium is greatly increased, realizing rapid and uniform cooling of the adsorbent and improving cooling efficiency. Through the circulation drive structure of the reflux pump and connecting pipe, the stable flow of the cooling medium is ensured, avoiding local temperature accumulation, ensuring the consistency of the adsorbent cooling effect, and effectively protecting the adsorbent adsorption performance from the influence of high temperature.

[0013] 2: Through the cooperation of air ducts, exhaust fans and activated carbon filters, the air containing VOCs in the cooling box is extracted in real time and purified to prevent harmful gases from leaking out and causing environmental pollution, thus meeting environmental emission requirements; the protective net in the air duct prevents foreign objects from entering, avoids damage to the exhaust fan and extends the service life of the filter components.

[0014] 3: By conducting a comprehensive inspection of the limit plate, connecting pipe, rotating block, support column, and casters before startup, potential faults can be eliminated in advance, ensuring a smooth collection process. By adjusting the angle of the connecting pipe with the rotating block and using the limit plate for positioning, the collection box can be accurately aligned with the discharge port, preventing adsorbent spillage. The centralized collection by the collection box and the flexible movement of the casters significantly reduce the intensity of manual handling and improve handling efficiency.

[0017] Example

[0018] Reference Figures 1-5A VOC adsorbent discharge cooling device includes a cooling box 1, a cooling component, a collection component, a filter component, and a support component. The cooling component includes a partition 21 fixedly installed inside the cooling box 1. A cooling pipe 24 is fixedly installed inside the partition 21, and one end of the cooling pipe 24 extends through the interior of the cooling box 1. A feed hopper 2 is fixedly installed at one end of the cooling pipe 24. A water inlet pipe 7 is fixedly installed on the top of the cooling box 1, and a sealing cover 6 is movably installed inside the water inlet pipe 7. A return pump 3 is fixedly installed on the left side of the cooling box 1. A 4 is fixedly installed between the return pump 3 and the cooling box 1. Four guide plates 22 are fixedly installed inside the cooling box 1, and a third connecting pipe 23 is fixedly installed between every two guide plates 22.

[0019] The circulation drive structure of the reflux pump 3 and connecting pipe 4 ensures stable flow of the cooling medium, avoids local temperature accumulation, ensures consistent cooling effect of the adsorbent, and effectively protects the adsorption performance of the adsorbent from the influence of high temperature.

[0020] A third connecting pipe 23 is fixedly installed between the return pump 3 and the guide plate 22. A discharge port 11 is fixedly installed at the bottom of the cooling box 1. A cavity is provided inside the guide plate 22. A cavity 20 is opened inside the cooling box 1, and the cavity 20 is fixedly connected to the cavity inside the uppermost guide plate 22. A water outlet pipe 16 is fixedly installed on the right side of the cooling box 1.

[0021] The reflux pump is model ISG50-125, and the reflux pump 3 is powered by an electric motor, which drives the impeller in the pump body to rotate at high speed, creating a negative pressure in the pump chamber. This draws the cooling medium, such as industrial cooling water or ethylene glycol aqueous solution, from the cooling box 1 into the pump body through the connecting pipe 4. The centrifugal force generated by the impeller rotation pressurizes the cooling medium, which is then transported to the cavity of the guide plate 22 through the connection structure between the reflux pump and the guide plate 22. This drives the cooling medium to continuously circulate in the loop composed of the cooling box 1, the guide plate 22, and the third connecting pipe 23, ensuring that the cooling medium and the VOC adsorbent in the cooling pipe 24 exchange heat efficiently and stably, maintaining the consistency of the device's cooling effect.

[0022] By precisely connecting the discharge port 11 with the collection component, the adsorbent after cooling is collected in a concentrated manner. Combined with the convenient transfer structure of the collection component, the intensity of manual operation is reduced. The design of discharging or recycling the cooling medium through the water outlet pipe 16 reduces resource waste and lowers operating costs. The overall device takes into account cooling efficiency, environmental protection and practicality, and is suitable for large-scale VOC adsorbent production scenarios.

[0023] The feed hopper 2 and the cooling pipe 24 are arranged in pairs, with a total of six pairs fixed inside the cooling box 1.

[0024] The filter assembly includes an air duct 14 fixedly installed on the left side of the cooling box 1, a mounting base 18 fixedly installed inside the air duct 14, an exhaust fan 19 fixedly installed on the top of the mounting base 18, an activated carbon filter screen 17 fixedly installed inside the cooling box 1, and a protective net 15 fixedly installed inside the air duct 14.

[0025] In this embodiment, the sealing cover 6 is first opened, and the cooling medium is injected into the cooling box 1 through the water inlet pipe 7. After the injection is completed, the sealing cover 6 is closed. Then, the VOC adsorbent to be cooled is put into the corresponding cooling pipe 24 through the six sets of two-in-two feed hoppers 2. The adsorbent enters the interior of the cooling box 1 along the cooling pipe 24.

[0026] The cooling medium flows into the cavity of the uppermost guide plate 22 through the cavity 20 opened inside the cooling box 1, and then circulates between each guide plate 22 through the third connecting pipe 23 between each pair of guide plates 22. During the process, it exchanges heat with the cooling pipe 24 and the internal adsorbent to achieve the cooling of the adsorbent. At the same time, the return pump 3 is started, and the stable circulation of the cooling medium is ensured through the connecting pipe 4 between the return pump 3 and the cooling box 1 and the connection structure between the return pump 3 and the guide plate 22. During the cooling process, the exhaust fan 19 on the fixed seat 18 inside the air duct 14 is started. The exhaust fan 19 drives the air flow inside the cooling box 1. VOC gases that may be contained in the air are filtered and purified by the internal activated carbon filter 17 and discharged through the air duct 14. The protective net 15 inside the air duct 14 can prevent foreign objects from entering. The VOC adsorbent after cooling is finally discharged from the discharge port 11 at the bottom of the cooling box 1. The VOC adsorbent is collected by the collection component, while the cooling medium that has participated in heat exchange is discharged from the water outlet 16 on the right side of the cooling box 1 or recycled for reuse.

[0027] Example

[0028] Reference Figure 6 A VOC adsorbent discharge cooling device is characterized in that the collection component includes a limiting plate 25 fixedly installed on the back of the discharge port 11, a connecting pipe 27 is movably installed inside the limiting plate 25, a rotating block 26 is hinged to the back of the connecting pipe 27, a collection box 12 is fixedly installed on the front of the connecting pipe 27, four support columns 28 are fixedly installed at the bottom of the collection box 12, and universal wheels 29 are fixedly installed at the bottom of each of the four support columns 28.

[0029] A push rod 13 is fixedly installed on the front of the collection box 12, and the outer surface of the push rod 13 is L-shaped. Because the outer surface of the push rod 13 is L-shaped and the L-shape of 13 is ergonomic, it is easy to hold the push rod 13 to push the collection box 12 to move.

[0030] The support assembly includes four support plates 8 fixedly installed at the bottom of the cooling box 1, and a fixing plate 10 is fixedly installed between every two support plates 8. A reinforcing rib 9 is fixedly installed at the angle between the support plate 8 and the fixing plate 10, and the outer surface of the reinforcing rib 9 is triangular.

[0031] The cooling box 1 is stably supported by four support plates 8 at the bottom. Together with the fixing plate 10 between the support plates 8 and the triangular reinforcing ribs 9, the structural strength is greatly improved, the weight of the equipment is distributed, the deformation and shaking of the device are effectively prevented, the stable operation of the adsorbent cooling and discharge process is ensured, and the overall durability of the structure is enhanced.

[0032] In this embodiment, before starting the VOC adsorbent discharge cooling device, the status of each component of the collection assembly is checked to confirm that the limiting plate 25 is firmly fixed on the back of the discharge port 11, the connecting pipe 27 moves smoothly inside the limiting plate 25, and there is no jamming at the hinge of the rotating block 26 and the connecting pipe 27. At the same time, the four support columns 28 and the bottom universal wheels 29 at the bottom of the collection box 12 are checked to see if they are intact and roll flexibly. Subsequently, by rotating the rotating block 26 on the back of the connecting pipe 27, the angle of the connecting pipe 27 is adjusted so that the collection box 12 fixed on the front of the connecting pipe 27 is precisely aligned with the bottom of the discharge port 11. The limiting plate 25 can limit the range of motion of the connecting pipe 27 to prevent the collection box 12 from shifting and causing the adsorbent to spill. After the device completes the adsorbent cooling process, the cooled VOC adsorbent is discharged from the outlet 11 and flows smoothly into the collection box 12 through the connecting pipe 27 for centralized collection. When the adsorbent in the collection box 12 reaches the preset collection amount, push the collection box 12 directly and move it easily with the help of the casters 29 on the bottom support column 28 to transfer the adsorbent to the subsequent treatment area. If the collection position needs to be adjusted, the angle of the connecting tube 27 can be finely adjusted again by rotating block 26 to ensure that the collection process is continuously stable.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
