Description

Technical Field

[0001] This utility model relates to the field of organic matter adsorption technology, specifically to an organic matter adsorption box for photovoltaic production. Background Technology

[0002] The production process of photovoltaic cells (such as silicon wafer cleaning, coating, and etching) generates waste gas containing volatile organic compounds (VOCs), small amounts of dust, and acidic gases. Direct emission of these organic compounds will not only cause air pollution but may also harm the health of operators, and will not comply with the emission limits stipulated in environmental regulations.

[0003] Existing adsorption devices for treating this type of waste gas have the following drawbacks: Insufficient purification efficiency: They mostly use single activated carbon adsorption or simple filtration, which cannot simultaneously and efficiently remove dust, VOCs, and small amounts of acidic substances, resulting in emissions that may still exceed standards; Unreasonable structural design: The adsorption packing material does not have sufficient contact with the airflow, and dead air zones are easily formed in some areas, reducing adsorption efficiency; Inconvenient monitoring and maintenance: There is a lack of real-time monitoring of key parameters such as temperature and pressure difference inside the adsorption chamber, making it impossible to promptly determine the clogging or failure status of the filter components; Equipment maintenance requires disassembling multiple parts, which is cumbersome and affects production continuity. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a photovoltaic production organic matter adsorption box that can achieve multiple purification, is easy to monitor and maintain, and has strong adaptability.

[0005] The technical solution adopted by this utility model is as follows: a photovoltaic production organic matter adsorption box, including an adsorption box body, an air inlet and an air outlet arranged opposite to each other outside the adsorption box body, and an adsorption filter assembly and a fire-fighting assembly; the adsorption filter assembly includes a filter and activated carbon packing, the filter is located inside the adsorption box body near the air inlet, the activated carbon packing is located downstream of the filter, and the adsorption box body is provided with spaced-apart packing racks, with the activated carbon packing inside the packing racks; the fire-fighting assembly includes spray pipes arranged at the top of the adsorption box body between adjacent packing racks, the spray pipes are provided with spaced-apart nozzles, and each spray pipe is connected to a fire-fighting pipeline.

[0006] In this technical solution, the adsorption box body uses an adsorption filter assembly to adsorb and filter organic matter in the flue gas. That is, the flue gas is filtered by the filter and then the organic matter is adsorbed by the activated carbon packing. If the equipment catches fire due to high temperature during use, fire can be sprayed through the various spray pipes and nozzles of the fire-fighting assembly to suppress the spread of fire in time, effectively prevent the adsorption box body and internal core components from being completely damaged by fire, and significantly reduce equipment maintenance costs and production downtime losses.

[0007] Preferably, the filler frame is provided with material layer sealing plates at both ends.

[0008] Preferably, the air inlet and air outlet are equipped with thermocouple interfaces.

[0009] Preferably, the adsorption box body is provided with a variable diameter section for installing an air inlet and an air outlet.

[0010] Preferably, a differential pressure sensor module is provided inside the adsorption box.

[0011] Preferably, the bottom of the adsorption box body is provided with a drain port.

[0012] Preferably, the bottom of the adsorption box body is provided with a box base, and a support frame is installed at the lower end of the box base.

[0013] Preferably, a ladder is provided on the outside of the adsorption box body, the ladder is connected to a maintenance rack located at the upper end of the adsorption box body, and a protective cage is provided on the outside of the ladder.

[0014] The beneficial effects of this invention are as follows: The adsorption filtration component of this invention adopts a two-stage treatment structure of filtration and adsorption to synergistically improve purification accuracy. The filter pre-treats particulate matter and other impurities in the flue gas, reducing the risk of blockage by the activated carbon packing. The activated carbon packing is placed in layers through spaced-apart packing racks, increasing the contact area with the flue gas, extending the adsorption path, and significantly improving the adsorption efficiency of organic matter. The spray pipes of the fire-fighting component are precisely arranged between adjacent packing racks, and with the spaced-apart nozzles, directional spraying can be carried out on the areas where activated carbon packing accumulates, covering key fire risk points. Compared with the integrated spray structure, it is more precise and responds more quickly, and has high practical value. Attached Figure Description

Detailed Implementation

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0021] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0022] like Figures 1 to 3 As shown in the figure, a specific embodiment of this utility model provides an organic matter adsorption box for photovoltaic production, including an adsorption box body 100, an air inlet 110 and an air outlet 120 arranged opposite to each other outside the adsorption box body, and an adsorption filtration assembly and a fire-fighting assembly; the adsorption filtration assembly includes a filter 200 and activated carbon packing 300, the filter 200 is located inside the adsorption box body 100 near the air inlet 110, the activated carbon packing 300 is located downstream of the filter 200, and the adsorption box body 100 is provided with spaced-apart packing racks 400, with the activated carbon packing 300 located inside the packing racks 400; the fire-fighting assembly includes spray pipes 500 arranged at the top of the adsorption box body 100 corresponding to adjacent packing racks 400, the spray pipes 500 are provided with spaced-apart nozzles 510, and each spray pipe 500 is connected to a fire-fighting pipeline.

[0023] like Figures 1 to 3 As shown, through the above-described configuration, this embodiment uses an adsorption and filtration assembly within the adsorption box body 100 to adsorb and filter organic matter in the flue gas. Specifically, the flue gas is filtered by the filter 200 and then adsorbed by the activated carbon packing 300. In this embodiment, the activated carbon packing 300 is layered using spaced-apart packing racks 400, increasing the contact area with the airflow and reducing dead zones. The fire-fighting component's sprinkler pipes 500 are precisely positioned between adjacent packing racks 400, and in conjunction with spaced-apart nozzles, can provide directional spraying to areas where the activated carbon packing accumulates, covering key fire risk points. Compared to an integrated sprinkler structure, this method offers more precise fire suppression and a faster response.

[0024] As mentioned above, multiple layers of activated carbon packing 300 need to be deployed inside the packing frame 400. In this embodiment, material layer sealing plates 600 are provided at both ends of the packing frame 400. The material layer sealing plates 600 at both ends of the packing frame 400 can prevent the activated carbon packing 300 from leaking. In practical applications, the packing frame 400 adopts a carbon layer skeleton structure.

[0025] like Figures 1 to 3 As shown, in this embodiment, thermocouple interfaces 700 are provided in the air inlet 110 and the air outlet 120. Temperature sensors can be installed in the thermocouple interfaces 700 to monitor changes in exhaust gas temperature in real time, preventing high-temperature damage to the activated carbon. Furthermore, by monitoring the inlet and outlet temperatures of the flue gas in real time, abnormal high-temperature hazards can be detected promptly.

[0026] like Figures 1 to 3 As shown, since the adsorption box body 100 needs to be connected to the flue gas pipeline through the air inlet 110 and the air outlet 120, this embodiment provides a variable diameter section 130 on the adsorption box body 100 for installing the air inlet 110 and the air outlet 120. The air inlet 110 and the air outlet 120 are installed through the variable diameter section 130, which can be adapted to different specifications of exhaust gas pipelines, reducing installation and modification costs. Flange structures are provided on the air inlet 110 and the air outlet 120 for connecting the pipeline.

[0027] like Figures 1 to 3 As shown, a differential pressure sensor module 800 is installed inside the adsorption tank body 100. The differential pressure sensor module 800 inside the adsorption tank body 100 can monitor changes in internal resistance in real time. By using differential pressure data, it can accurately determine the degree of clogging or adsorption saturation of the filter and activated carbon packing, facilitating timely replacement and maintenance and preventing excessive organic matter emissions due to decreased adsorption capacity. In practical applications, the signal lines of the differential pressure sensor module 800 are arranged in rigid tubing, which is fixed to the inner wall of the adsorption tank body 100 using angle steel.

[0028] When in use, this device needs to be sprayed through 500 spray pipes. In order to discharge the liquid, this embodiment has a drain port at the bottom of the adsorption box body 100. The bottom drain port facilitates the collection and discharge of waste liquid after fire spraying or cleaning, and avoids the accumulation of liquid in the box from damaging the equipment.

[0029] like Figures 1 to 3 As shown, the bottom of the adsorption box body 100 is provided with a box base 900, and a support frame 910 is installed at the lower end of the box base 900. The box base 900 and the support frame 910 enhance the overall stability of the equipment and adapt to the ground installation environment of the photovoltaic workshop. In addition, the inner wall of the adsorption box body 100 is also provided with a reinforcing rib structure to ensure structural strength.

[0030] like Figures 1 to 3As shown, a ladder 1000 is provided on the outside of the adsorption box body 100. The ladder 1000 is connected to a maintenance rack 1010 located at the upper end of the adsorption box body 100. A protective cage 1020 is provided on the outside of the ladder 1000. The ladder 1000 and the maintenance rack 1010 (in conjunction with the protective cage 1020) on the outside of the adsorption box body 100 facilitate operators to safely and quickly replace the packing and perform equipment maintenance, reducing downtime. In addition, the adsorption box body 100 can also be provided with maintenance ports, observation ports and other structures to facilitate maintenance and observation of the equipment's operating status.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
