Fig. 1 is a schematic diagram showing the principle and structure of the first embodiment of the modularized constant dehumidification heat recovery device and the energy-saving constant humidity adjustment method of the present invention, including: a coating machine oven 100 and an anode modular constant dehumidification heat recovery device 200; coating The gas inlet and outlet of the coating machine oven 100 are airtightly connected with the air supply port and the air exhaust port of the anode modular constant exhaust heat recovery device 200, so that the exhaust gas in the coating machine oven 100 is introduced into the anode modular through the air exhaust port The constant exhaust heat recovery device 200, the fresh air from the outside is introduced into the coating machine oven 100 through the air supply port; the anode modular constant exhaust heat recovery device 200 should at least include a heat exchanger 201, an air supply fan 202, and an exhaust fan 207 , an automatic exhaust air volume regulator 209 and a humidity sensor 206, wherein the heat exchanger 201 divides the interior of the anode modular constant exhaust heat recovery device 200 into an air supply air duct and an exhaust air duct, and the air supply fan 202 and the exhaust air duct The blower fan 207 is respectively arranged in the air supply duct and the exhaust air duct correspondingly, and is used to introduce fresh air into the coating machine oven 100, and exhaust gas is exported from the coating machine oven 100. Since the coating machine oven 100 The exhaust gas discharged from the oven has a relatively high temperature (usually about 100°C), while the fresh air entering the oven from the outside air has a relatively low temperature and needs to be heated to perform the drying function. Therefore, setting the heat exchanger 201 can convert all The heat exchange between the fresh air and the exhaust air can reduce the heat of the exhaust air discharged to the outside air on the one hand, and preheat the fresh air on the other hand, reducing the system energy consumption required to reheat the fresh air to a specified temperature, thereby saving energy. synergistic effect. The heat exchanger 201 of the present invention is preferably a two-way corrugated plate heat exchanger, and it is placed in a rhombus shape, but any other type of heat exchanger that can play a role in heat exchange, such as a heat pipe heat exchanger, a wheel heat exchanger , and other various air-air heat exchangers and their adaptable fixed installation methods should be covered within the protection scope of the present invention.

In this embodiment, the humidity sensor 206 is arranged in the exhaust air duct to detect the humidity value of the airflow inside the oven 100; the anode modular constant exhaust heat recovery device 200 also includes an automatic exhaust air volume regulator 209. The input terminal of the automatic exhaust air volume regulator 209 is electrically connected to the humidity sensor 206 to receive the humidity value detected by the humidity sensor 206. In a preferred solution, the humidity value standard can be based on the user's experience , and/or the external environment, and/or the technological requirements of drying and set separately; Exhaust air volume: As shown in Figure 2, when the exhaust air humidity is detected to be less than the humidity value standard, if it is detected that the exhaust air volume is less than the minimum exhaust air volume, the current air volume operation will be maintained; if it is detected that the exhaust air volume is greater than the minimum exhaust air volume When the value is higher, reduce the exhaust air volume; when the detected exhaust air humidity is greater than the humidity value standard, increase the exhaust air; if the detected exhaust air humidity is equal to or basically equal to the humidity value standard, then maintain the current air volume. By controlling the power frequency of the exhaust fan through the humidity detection and comparison results, the exhaust air can be reduced as much as possible and the operating energy consumption can be reduced under the premise of ensuring the maximum dehumidification required.

In this embodiment, the air supply volume of the air supply fan 202 can automatically supply air according to a certain ratio according to the exhaust air volume and the supply air volume. The exhaust air volume automatic regulator 209 is signal-connected to the air supply air volume automatic regulator 204, and the exhaust air volume and supply air volume are automatically supplied according to a certain ratio. Preferably, the ratio can be specifically set according to user experience and process requirements. Specifically, the exhaust air volume and air supply air volume are set according to the ratio of 1:0.9-0.95, when the humidity sensor 206 detects that the air humidity in the oven is 33.0g/kg (greater than the standard humidity value of 25g/kg), it means As the air humidity in the oven increases, the exhaust air volume needs to be increased to 70,000 m³/h, and the air supply volume will be automatically adjusted to 63,000 m³/h according to the set ratio of exhaust air volume to supply air volume; when the humidity sensor 206 detects that the air humidity in the oven is 25.2 g/kg (the humidity value standard is 25g/kg, and the distance between the humidity value and the humidity value standard is ±2, which is considered to be basically equal to the humidity value standard), indicating that the air humidity in the oven can meet the process requirements. At this time, no To increase the exhaust air volume, you only need to maintain the current exhaust air volume, and the air supply air volume will be automatically maintained according to the set ratio of exhaust air volume to supply air volume; when the humidity sensor 206 in the oven has an air humidity of 21 g/kg (less than the standard humidity value of 25 g/kg), indicating that the air in the oven is very dry and can fully meet the drying requirements. At this time, it is only necessary to keep the exhaust air volume as small as possible to meet the technological level, thereby reducing the energy consumption of the system, that is : If it is detected that the exhaust air volume is less than the minimum exhaust air volume of 45000 m³/h, the current air volume operation will be maintained. Correspondingly, the supply air volume will also be automatically maintained according to the set ratio of the exhaust air volume to the supply air volume; When it is detected that the exhaust air volume is greater than the minimum value of the exhaust air volume, the exhaust air volume will be reduced to the minimum exhaust air volume. Correspondingly, according to the set ratio of the exhaust air volume to the supply air volume, the supply air volume will also be automatically reduced to corresponding minimum value. In this embodiment, the air supply volume can be automatically adjusted according to the exhaust air volume through a proportional adjustment method, and the energy consumption of the system can be reduced while meeting the humidity removal requirements.

Preferably, in order to further optimize the system performance of the anode modular constant exhaust heat recovery device 200, multiple sets of devices can be further added, for example: add a fresh air filter 210 to strictly filter the fresh air introduced into the coating machine oven 100 to meet Drying process requirements, to prevent dust and other contamination of the electrode sheet during the drying process; set the exhaust fan 207 as a frequency conversion fan, specifically: the exhaust fan inverter 208 combined with the exhaust fan 207 in the form of adjusting the frequency of the power supply Exhaust air volume to make air volume adjustment more convenient; and guide shower water seal 211 to discharge the liquid condensed after heat exchange out of the system in time to prevent condensed water from accumulating in the system; preferably, the humidity value standard in this embodiment The parameters of the minimum value of the exhaust air volume can be specifically set according to the external environment and actual process needs, which optimizes the efficiency and effect of the device under different conditions and broadens the range of use of the device under different conditions; although the above multiple sets of devices are It is shown in Embodiment 1, it should be understood that it is only a preferred embodiment for the system to realize the function, not the minimum configuration requirement for the system to realize the function, and should not be construed as limiting the protection scope of the claims.

Figure 3 is a schematic diagram of the principle and structure of the second embodiment of the modularized constant exhaust heat recovery device and the energy-saving constant humidity adjustment method of the present invention. Compared with the first embodiment, the main difference of this embodiment lies in the change of the air supply logic. In the embodiment, the coating machine oven 100 is provided with a static pressure sensor 205 to detect the static pressure value in the oven, and the air supply logic is executed according to the static pressure value inside the oven measured by the static pressure sensor 205, and the automatic air volume regulator 204 The air supply volume of the air blower 202 is adjusted.

The specific air supply logic is as follows: when the static pressure value detected by the static pressure sensor 205 is less than the static pressure standard value parameter, the air supply volume needs to be increased at this time; Air volume; when the detected static pressure value is equal to or basically equal to the static pressure standard value parameter, the current air volume operation will be maintained. Specifically, when the humidity sensor 206 detects that the air humidity in the oven is 33.0g/kg (greater than the standard humidity value of 25g/kg), it means that the air humidity in the oven has increased, and the exhaust air volume needs to be increased to 70000m³/h. The static pressure value detected by the static pressure sensor 205 will be less than the static pressure standard value parameter -10Pa, then it is necessary to automatically increase the air supply volume to 63000 m³/h; when the humidity sensor 206 detects that the air humidity in the oven is 26g/kg (such as The humidity value standard is 25g/kg, and the distance between the humidity value and the humidity value standard is ±2, which is considered to be basically equal to the humidity value standard), indicating that the air humidity in the oven can meet the process requirements. At this time, there is no need to increase the exhaust air volume, just maintain the current exhaust air At this time, the static pressure value detected by the static pressure sensor 205 will also be equal to or substantially equal to the static pressure standard value parameter (the static pressure standard value-10Pa, the static pressure value ± 5Pa from the static pressure standard value is considered to be basically equal to the static pressure standard value), then maintain the current air volume operation; when the air humidity in the humidity sensor 206 oven is 21g/kg (less than the humidity value standard 25g/kg), it means that the air in the oven is very dry and can fully meet the drying requirements. The smallest possible exhaust air volume can meet the technical level, thereby reducing system energy consumption, that is, if it is detected that the exhaust air volume is less than the minimum exhaust air volume of 45000m³/h, the current air volume will be maintained. Correspondingly, the detected The static pressure value should be greater than the static pressure standard value parameter, then reduce the air supply volume to 43000m³/h.

Preferably, the air supply fan 202 in this embodiment is also preferably a variable frequency fan, specifically: the air supply fan frequency converter 203 is combined with the form of the air supply fan 202 to adjust the exhaust air volume by changing the power supply frequency, so that the air volume adjustment is more efficient. Convenience; in this embodiment, the adjustment step of the exhaust air volume and the adjustment step of the air supply air volume can be adjusted synchronously or asynchronously, that is, the adjustment step of the exhaust air volume and the adjustment step of the air supply air volume can be adjusted at the same time, or the exhaust air volume adjustment step can be adjusted simultaneously. The air volume adjustment step can be adjusted before or after the air supply air volume adjustment step; preferably, the static pressure standard value parameter in the oven in this embodiment can also be specifically set according to the external environment and actual process needs, optimizing the The efficiency and effect of the device under different conditions widen the range of use of the device under different conditions.

In this embodiment, the power frequency of the exhaust fan is controlled through the detection and comparison results of humidity and air volume, which can reduce the exhaust air as much as possible and reduce the energy consumption of operation under the premise of ensuring the maximum required moisture removal; and through static pressure detection and comparison Results Automatically control the power supply frequency of the air supply fan, and use the proportional control and adjustment between the two to reduce the exhaust and supply air volume as much as possible, and further realize the optimal energy allocation under the premise of meeting the production process requirements.

Fig. 5 is a schematic diagram of the principle and structure of the third embodiment of the modular constant exhaust heat recovery device and the energy-saving constant humidity adjustment method of the present invention. Compared with the second embodiment, the main difference of this embodiment is that the heat exchanger 201 can be set as Two heat exchangers are used in series, and the heat exchangers are preferably plate heat exchangers arranged in a diamond shape. However, it should be understood that the type, quantity and arrangement of the heat exchangers 201 can be adjusted by those skilled in the art according to actual needs.

Setting more than two heat exchangers can further improve the efficiency and effect of heat exchange. Taking two heat exchangers 201 as an example, the high-temperature exhaust gas undergoes two-stage heat exchange. Compared with one heat exchanger, the temperature can be reduced by about 30%. It meets the emission standards; while the external fresh air undergoes two-stage heat exchange, compared with a heat exchanger, the temperature can be increased by about 30%, and only a little heating is needed to meet the needs of the drying temperature. Compared with single-stage heat exchange, multi-stage heat exchange has more sufficient heat exchange and lower energy consumption, which is more in line with the needs of production and energy saving.

It should be understood that although this description is described according to implementation modes, not each implementation mode only contains an independent technical solution, and this description in the description is only for clarity, and those skilled in the art should take the description as a whole, and each The technical solutions in the embodiments can also be properly combined to form other embodiments that can be understood by those skilled in the art.
