Description

Technical Field

[0001] This utility model relates to the field of deodorization equipment technology, specifically to a photovoltaic energy-saving deodorization device for a biochemical pool. Background Technology

[0002] During biochemical reactions, biological treatment tanks emit foul odors that affect the surrounding environment. Therefore, specialized deodorization equipment is typically installed to address this issue. Currently, deodorization equipment for biological treatment tanks generally requires a separate power supply to power its internal electrical control system (such as the fans and circulating pumps that control the deodorization system). However, due to the high cost and low resource utilization of this method, most biological treatment tank deodorization equipment now utilizes solar photovoltaic modules for extensive energy absorption to power the electrical control system.

[0003] However, because the photoelectric conversion efficiency of photovoltaic modules cannot reach the ideal state, some solar radiation is converted into heat energy and lost. Existing deodorization equipment is unable to utilize this heat energy, resulting in low resource utilization and poor energy-saving effect. Utility Model Content

[0004] The purpose of this utility model is to provide a photovoltaic energy-saving deodorization device for biochemical ponds, so as to solve the technical problem that the energy-saving effect is weak in the existing technology because the deodorization device is difficult to reuse heat energy.

[0005] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0006] A photovoltaic energy-saving deodorization device for a biochemical pool includes a biochemical filter bed, a deodorization system for deodorizing the interior of the biochemical filter bed, and an electrical control system for controlling the start-up of the deodorization system. A sealed inverted membrane is installed on the top of the biochemical filter bed, forming a deodorization space between the sealed inverted membrane and the biochemical filter bed. A photovoltaic module is mounted on the top of the sealed inverted membrane via a metal mounting bracket. The photovoltaic module is electrically connected to the electrical control system. A sealing cover is provided around the photovoltaic module. The flexible photovoltaic module, the sealing cover, and the sealed inverted membrane together enclose a heat flow cavity.

[0007] The bottom of the biochemical filter bed is provided with a cold flow chamber, which is connected to the hot flow chamber through a circulating air duct. The circulating air duct is located on the side wall of the biochemical filter bed.

[0008] In a preferred embodiment of this utility model, the circulating air duct is disposed on both side walls of the biochemical filter bed, and the two ends of the circulating air duct are respectively connected to the hot flow chamber and the cold flow chamber through a shut-off valve. A circulating fan is disposed inside the circulating air duct, and the air outlet of the circulating fan is respectively directed towards the hot flow chamber and the cold flow chamber. A temperature sensor is disposed inside both the cold flow chamber and the hot flow chamber.

[0009] In a preferred embodiment of this utility model, an energy storage medium is provided inside the heat flow cavity. The energy storage medium is connected to the bottom surface of the photovoltaic module through a connector. The energy storage medium includes multiple energy storage tubes, which are arranged linearly below the photovoltaic module. An energy-absorbing flexible sheet is wrapped around the outside of each energy storage tube, and the energy-absorbing flexible sheet is installed on the bottom surface of the photovoltaic module through a connector.

[0010] As a preferred embodiment of this utility model, a heat-conducting fin is provided on the bottom surface of the cold flow cavity, the heat-conducting fin is disposed inside the cold flow cavity, and a heat insulation layer is provided on the outside of the cold flow cavity.

[0011] As a preferred embodiment of this utility model, the heat insulation layer includes an inner heating layer and an outer heat insulation layer. The inner heating layer is electrically connected to the energy storage module in the photovoltaic module. The inner heating layer is disposed close to the interior of the cold flow cavity. When the inner heating layer is powered on, it releases heat to the interior of the cold flow cavity.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] This invention forms a hot flow cavity on the top of the inverted membrane using a sealing cover and photovoltaic modules. A circulating air duct connects the hot flow cavity and the cold flow cavity to form a circulating channel. The circulating airflow is used as a heat exchange medium to transfer the heat flow in the hot flow cavity to the cold flow cavity to heat the biochemical filter bed, thereby improving its internal biochemical reaction efficiency. At the same time, the cold flow in the cold flow cavity is transferred to the hot flow cavity to cool the photovoltaic modules, improving their service life. This results in higher energy efficiency for the overall device. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, this utility model provides a photovoltaic energy-saving deodorization device for a biochemical pool, including a biochemical filter bed 1, a deodorization system 2 for deodorizing the interior of the biochemical filter bed 1, and an electrical control system 3 for controlling the start of the deodorization system 2. A sealing inverted membrane 4 is installed on the top of the biochemical filter bed 1, forming a deodorization space between the sealing inverted membrane 4 and the biochemical filter bed 1. A photovoltaic module 5 is installed on the top of the sealing inverted membrane 4 through a metal mounting bracket. The photovoltaic module 5 is electrically connected to the electrical control system 3. A sealing cover 6 is provided around the photovoltaic module 5. The flexible photovoltaic module 5, the sealing cover 6, and the inverted membrane together enclose a heat flow cavity 7.

[0024] A cold flow chamber 8 is provided at the bottom of the biochemical filter bed 1. The cold flow chamber 8 is connected to the hot flow chamber 7 through a circulating air duct 9, which is located on the side wall of the biochemical filter bed 1. Depending on the actual construction scale, the photovoltaic module 5 may only be laid on a portion of the top area of ​​the sealing inverted membrane 4, instead of laying the entire sealing inverted membrane 4.

[0025] The hot flow chamber 7, cold flow chamber 8, and circulating air duct 9 together form an airflow circulation channel. The hot flow chamber 7 at the top heats up during the photoelectric conversion of the photovoltaic module 5. At this time, the heat inside it moves through the circulating air duct 9 to the cold flow chamber 8 at the bottom of the biochemical filter bed 1, which heats up the cold flow chamber 8 while cooling down the hot flow chamber 7.

[0026] Furthermore, the circulating air duct 9 is installed on both sides of the biochemical filter bed 1. The two ends of the circulating air duct 9 are connected to the hot flow chamber 7 and the cold flow chamber 8 respectively through the shut-off valve 10. A circulating fan 11 is installed inside the circulating air duct 9. The air outlet of the circulating fan 11 is directed towards the hot flow chamber 7 and the cold flow chamber 8 respectively. Temperature sensors 12 are installed in both the cold flow chamber 8 and the hot flow chamber 7.

[0027] like Figure 1 As shown, a circulating fan 11 is installed to accelerate the internal airflow. The circulating fan 11 is connected to the photovoltaic module 5 to improve energy efficiency. A shut-off valve 10 is installed to control the opening and closing of the hot flow chamber 7 and the cold flow chamber 8. This allows the hot and cold flows to be stored in the cold flow chamber 8 and the hot flow chamber 7 respectively, resulting in more thorough heat exchange. Furthermore, a temperature sensor 12 is signal-connected to the shut-off valve 10. When the temperature sensor 12 senses that the corresponding temperature in the hot flow chamber 7 and the cold flow chamber 8 has reached a preset value, it sends a signal to open or close the shut-off valve 10.

[0028] Furthermore, such as Figure 1 and Figure 4 As shown, an energy storage medium 13 is provided in the heat flow cavity 7. The energy storage medium 13 is connected to the bottom surface of the photovoltaic module 5 through a connector. The energy storage medium 13 includes multiple energy storage tubes 131, which are arranged linearly below the photovoltaic module 5. An energy-absorbing flexible sheet 132 is wrapped around the outside of the energy storage tubes 131. The energy-absorbing flexible sheet 132 is installed on the bottom surface of the photovoltaic module 5 through a connector.

[0029] Among them, the energy storage tube 131 can be made of sensible heat energy storage material and latent heat energy storage material to absorb and store the heat energy generated by the photovoltaic module 5. The energy storage tube 131 is wrapped by the energy-absorbing flexible sheet 132 to form an integrated structure and is installed on the bottom surface of the photovoltaic module 5 to expand the energy absorption efficiency.

[0030] The energy storage medium 13 forms a component that balances the temperature within the heat flow cavity 7. On one hand, after cold air enters the heat flow cavity 7, the energy storage medium 13 can absorb the low temperature and conduct it to the photovoltaic module 5 to cool it down. On the other hand, the energy storage medium 13 acts as a transition, preventing the heat within the heat flow cavity 7 from directly acting on the photovoltaic module 5, thus providing transitional protection.

[0031] In addition, a heat-conducting fin 14 is provided on the bottom surface of the cold flow cavity 8, and the heat-conducting fin 14 is disposed inside the cold flow cavity 8. An insulation layer 15 is provided on the outside of the cold flow cavity 8. The heat-conducting fin 14 can be a component with high thermal conductivity and certain pressure resistance, such as a steel plate, to support the biochemical materials inside the biochemical filter bed 1.

[0032] like Figure 3 As shown, the insulation layer 15 further includes an inner heating layer 151 and an outer insulation layer 152. The inner heating layer 151 is electrically connected to the energy storage module in the photovoltaic module 5. The inner heating layer 151 is located close to the interior of the cold flow cavity 8. After being powered on, the inner heating layer 151 releases heat to the interior of the cold flow cavity 8.

[0033] The insulation layer 15 serves two purposes: firstly, it prevents heat loss during internal airflow circulation, thus reducing the heating efficiency of the biochemical filter bed 1. Secondly, the insulation layer 15 includes an inner heating layer 151 and an outer insulation layer 152. When the photovoltaic module 5 does not receive solar radiation at night, the energy storage module inside the photovoltaic module 5 can power the inner heating layer 151, causing it to release heat into the cold flow chamber 8, thereby continuously heating the biochemical filter bed 1. This saves energy and enhances the efficiency of the biochemical reaction. The inner insulation layer 15 can be formed by sealing the heating element with a densely conductive material.

[0034] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
