Description

Technical Field

[0002] In the textile industry, wool, as an important natural fiber, is widely used due to its excellent warmth retention and comfort. During the processing of wool, drying is a crucial step, which directly affects the quality of wool and the efficiency of subsequent processing. Traditional wool drying methods mainly rely on hot air drying, and there is also the case of non-preheated drying. Although this method can remove the moisture in wool, there are still some problems. In plateau areas, due to the reasons of air pressure and oxygen content, using coal as a heat source is unstable, and it will pollute the local environment. There are also problems such as high energy consumption, easy heat damage to wool, and uneven drying.

However, the present application can be implemented in many other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the spirit of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

It should also be understood that the term "and / or" used in one or more embodiments of the present application refers to and includes any or all possible combinations of one or more of the associated listed items.

[0040] It should be understood that although the terms first, second, etc. may be used in one or more embodiments of the present application to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of one or more embodiments of the present application, the first may also be referred to as the second, and similarly, the second may also be referred to as the first.

[0041] In the present application, a wool drying device based on geothermal energy is provided, which will be described in detail in the following embodiments.

[0042] Figure 1 The structural schematic diagram of a wool drying device based on geothermal energy provided according to an embodiment of the present application is shown, which specifically includes a first drying area, a second drying area, and a third cooling area. Among them,

[0043] For the first drying area, heat is provided by a ground source heat pump device, and the temperature of the first drying area is higher than a first preset temperature and lower than a second preset temperature;

[0044] For the second drying area, heat is provided by the ground source heat pump device and a solar heat pump device, and the temperature of the second drying area is higher than the second preset temperature;

[0045] The temperature of the third cooling area is lower than a third preset temperature.

[0046] Among them, the production areas of wool are concentrated in areas with developed animal husbandry. Areas with developed animal husbandry are often grassland terrains, and grassland terrains are often distributed in plateau areas. As a key link in wool processing, coal is often used as the heat supply source for wool drying. However, due to reasons such as air pressure and oxygen content in plateau areas, using coal as the heat supply source cannot guarantee its heat supply stability, and the combustion products of fossil fuels will pollute the local environment. As a grassland area with a relatively fragile ecological environment, environmental pollution problems need to be taken seriously.

[0047] In addition, in areas with developed animal husbandry, there are often rich geothermal resources. Therefore, there is natural convenience in drying wool through geothermal energy. Therefore, by arranging a first drying area for preheating, a second drying area for drying, and a third cooling area for cooling, the drying of wool is realized.

[0048] Based on this, both the first drying area and the second drying area are provided with heat by a ground source heat pump device, effectively utilizing geothermal energy, and a solar heat pump device is arranged in the second drying area as a supplement when the heat output of the ground source heat pump device is insufficient.

[0049] In actual application scenarios, the first preset temperature ranges from 35°C to 45°C, the second preset temperature ranges from 75°C to 85°C, and the third preset temperature ranges from 35°C to 40°C. When the wool to be dried enters the first drying zone, the temperature in the first drying zone continuously increases until it reaches between 70°C and 80°C. When the wool to be dried enters the second drying zone, the temperature in the second drying zone continuously increases until it reaches between 85°C and 95°C.

[0050] In summary, through segmented drying and controlling the drying temperature in each drying process, it is ensured that the wool is properly temperature-treated in each drying zone, ensuring the removal of excess moisture during the wool drying process while maintaining the softness of the wool, avoiding damage to the wool. Moreover, geothermal energy is used throughout the drying process to reduce energy consumption, and solar energy is used as an auxiliary energy source to further reduce energy consumption and ensure the optimization effect of energy.

[0051] Furthermore, the first drying zone is equipped with a first sensor group, the second drying zone is equipped with a second sensor group, and the third cooling zone is equipped with a third sensor group.

[0052] Among them, the first sensor group, the second sensor group, and the third sensor group are all composed of multiple temperature sensors and multiple humidity sensors. The first sensor group is used to detect the temperature data and humidity data in the first drying zone, the second sensor group is used to detect the temperature data and humidity data in the second drying zone, and the third sensor group is used to detect the temperature data and humidity data in the third cooling zone.

[0053] Based on this, the temperature and humidity in each area involved in the wool drying process are detected in real time, ensuring the real-time adjustment of the drying strategy. Specifically, when it is detected that the temperature requirements in the first drying zone, the second drying zone, or the third cooling zone do not meet the preset requirements, the output power of the ground-source heat pump device and / or the solar heat pump device is adjusted. And when it is detected that in the first drying zone, the second drying zone, or the third cooling zone, the temperature rising speed exceeds the preset speed rising threshold, the output power of the ground-source heat pump device and / or the solar heat pump device is adjusted, so as to ensure that the temperature change during wool drying will not affect the wool quality.

[0054] Furthermore, the wool drying device based on geothermal energy further includes a transportation component for sequentially transporting the wool to be dried through the first drying zone, the second drying zone, and the third cooling zone.

[0055] In actual application scenarios, the transportation component is a belt conveyor, and the wool to be dried is conveyed through the conveyor belt, and the wool to be dried sequentially passes through the first drying zone, the second drying zone, and the third cooling zone.

[0056] Further, the treatment process of the wool to be dried in the first drying area is as follows in this embodiment:

[0057] Heat the first drying area through the ground source heat pump device so that the temperature of the first drying area reaches the first preset temperature; transport the wool to be dried to the first drying area through the transport component; based on the first sensor group arranged in a matrix in the first drying area, monitor the wool temperature of the wool to be dried until the wool temperature is higher than the preset first threshold, and then transport the wool to be dried to the second drying area through the transport component.

[0058] Among them, before the wool to be dried is transported to the first drying area, the temperature of the first drying area needs to be heated to the first preset temperature in advance, and the heating is realized through the ground source heat pump device. Moreover, the temperature sensors in the first sensor group monitor the temperature inside the first drying area in real time. After reaching the first preset temperature, a stop heating instruction is sent to the ground source heat pump device, and the ground source heat pump device adjusts the output power to keep the temperature of the first drying area from rising or falling, or the rising and falling amplitude is lower than the preset temperature floating threshold.

[0059] Based on this, after the heating in the first drying area is completed, the wool to be dried is transported to the first drying area. The multiple temperature sensors included in the first sensor group are distributed in the first drying area in a matrix form. When the wool to be dried arrives at the first drying area, the first sensor group detects the overall temperature change inside the first drying area and sends a temperature increase instruction to the ground source heat pump device. The ground source heat pump device increases its output power according to the preset power adjustment rate to heat the first drying area and raise the temperature inside the first drying area.

[0060] At the same time, among the first sensor group, the temperature sensors arranged near the transmission route of the wool to be dried monitor the temperature of the wool to be dried in real time, construct a temperature point cloud map associated with the wool to be dried according to the monitoring results, then construct a temperature model of the wool to be dried according to the temperature point cloud map, and monitor the wool temperature in real time through the temperature model until the wool temperature is higher than the preset first threshold. In the actual application scenario, the value range of the first threshold is 70°C - 80°C. When the wool temperature is higher than the preset first threshold, it is considered that the preheating is completed. The wool to be dried is transported to the second drying area through the transport component, and an instruction is sent to the ground source heat pump device to indicate it to adjust the output power so that the temperature of the first drying area drops to the first preset temperature, and then the next batch of wool to be dried enters the first drying area.

[0061] Further, the treatment process of the wool to be dried in the second drying area is as follows in this embodiment:

[0062] Heat the second drying area through the ground source heat pump device and / or the solar heat pump device so that the temperature of the second drying area reaches the second preset temperature; transport the wool to be dried that has been processed in the first drying area to the second drying area through the transport component; based on the second sensor group arranged in a matrix in the second drying area, detect the wool temperature and wool humidity of the wool to be dried until the wool temperature is higher than a preset second threshold and the wool humidity is lower than a preset third threshold, and then transport the wool to be dried to the third cooling area through the transport component.

[0063] Further, in the process of heating the second drying area through the ground source heat pump device and / or the solar heat pump device so that the temperature of the second drying area reaches the second preset temperature, in this embodiment, the specific implementation method is as follows:

[0064] Heat the second drying area through the ground source heat pump device, and monitor the temperature of the second drying area through the second sensor group; if the temperature of the second drying area is lower than the second preset temperature after a preset time, start the solar heat pump device; heat the second drying area jointly through the solar heat pump device and the ground source heat pump device so that the temperature of the second drying area reaches the second preset temperature.

[0065] Further, when the wool temperature is higher than the second threshold and the wool humidity is lower than the third threshold, continue to dry the wool to be dried in the second drying area until after a preset duration, and then transport the wool to be dried to the third cooling area through the transport component.

[0066] Among them, before the wool to be dried is transported to the second drying area, the second drying area also needs to be pre-heated in advance so that the temperature of the second drying area is higher than the second preset temperature. Specifically, first heat the second drying area through the ground source heat pump device, and the temperature sensor in the second sensor group monitors the temperature inside the second drying area in real time. After reaching the second preset temperature, send a stop heating instruction to the ground source heat pump device, and the ground source heat pump device adjusts the output power to keep the temperature of the second drying area from rising or falling, or the amplitude of rising and falling is lower than the preset temperature floating threshold.

[0067] In addition, if the second drying area is heated by a ground source heat pump device and does not reach the second preset temperature after a preset time, the solar heat pump device is started to assist in heating until the second preset temperature is reached. Then, the ground source heat pump device and the solar heat pump device are notified to adjust their output powers to keep the temperature of the second drying area from rising or falling, or the amplitude of rising and falling is lower than the preset temperature floating threshold. It should be noted that if neither the ground source heat pump device nor the solar heat pump device can heat the second drying area to the second preset temperature, the hot blast stove in the second circulation air duct is turned on, and all three devices heat the second drying area simultaneously.

[0068] After that, the wool to be dried is transported to the second drying area for drying. The second sensor group in the second drying area is the same as the first sensor group described above. By monitoring the overall temperature of the second drying area, it is determined whether the wool to be dried enters the second drying area. After entry, the temperature of the second drying area is increased. Multiple temperature sensors and multiple humidity sensors in the second sensor group are distributed in the second drying area in the same way as the temperature sensors in the first sensor group in the first drying area to construct a temperature model of the wool to be dried, and the humidity of the wool to be dried is also monitored in real time. When any one of the two conditions that the temperature of the wool to be dried in the second drying area is higher than the second threshold and the humidity is lower than the third threshold is not met, the drying continues.

[0069] In an actual application scenario, the second threshold is set to 85 °C and the third threshold is set to 15%. When both of the above two conditions are met, the drying continues for a preset duration to achieve the best drying effect. In an actual application scenario, according to the actual measurement, the optimal setting of this preset duration is 20 minutes. When all the drying processes are completed, the wool to be dried is transported to the third cooling area. At this time, the ground source heat pump device and / or the solar heat pump device adjust their output powers to lower the temperature of the second drying area until the second preset temperature is reached, and then the next batch of wool to be dried is allowed to enter the second drying area.

[0070] Furthermore, the processing process of the wool to be dried in the third cooling area is as follows in this embodiment:

[0071] Through the transportation component, the wool to be dried that has been processed in the second drying area is transported to the third cooling area; based on the third sensor group arranged in a matrix in the third cooling area, the wool temperature of the wool to be dried is detected until the wool temperature is lower than the preset fourth threshold, and then the wool to be dried is transported out of the third cooling area through the transportation component.

[0072] Among them, in the actual application scenario, the fourth threshold is generally set at 35°C - 40°C. After the wool to be dried is transported to the third cooling zone, it waits for the wool to be dried to cool down. The cooling method is air-cooling, and the temperature of the third drying zone is at room temperature. And the temperature sensors in the third sensor group are arranged in the third cooling zone in the same way as the temperature sensors in the first sensor group are arranged in the first drying zone, and the wool temperature of the wool to be dried in the third cooling zone is monitored in real time. For the specific monitoring method, please refer to the above description of the first temperature sensor group monitoring the wool temperature of the wool to be dried in the first drying zone, which will not be elaborated in this embodiment.

[0073] Furthermore, the wool drying device using geothermal energy further includes a first circulation air duct, a second circulation air duct, and a third circulation air duct. Among them, the first circulation air duct connects the first drying zone and the ground source heat pump device; the second circulation air duct connects the second drying zone, the ground source heat pump device, and the solar heat pump device, and a hot blast stove is arranged; the third circulation air duct connects the third cooling zone. Among them, the first circulation air duct, the second circulation air duct, and the third circulation air duct are all driven by a fan to drive the air flow, and a dust removal and dehumidification device is provided.

[0074] Furthermore, the ground source heat pump device includes a heat pump unit, and the solar heat pump device includes a solar panel. Among them, a groundwater circulation pipeline is arranged between the heat pump unit and the underground water resource. The groundwater circulation pipeline is coiled in the first drying zone, and the overall direction is opposite to that of the first circulation air duct; the solar panel is provided with a medium circulation pipeline, and the medium circulation pipeline is coiled in the first drying zone, and the overall direction is opposite to that of the first circulation air duct.

[0075] Among them, the first circulation air duct connects the first drying zone and dusts and dehumidifies the first drying zone. The second circulation air duct connects the second drying zone and dusts and dehumidifies the second drying zone. The third circulation air duct connects the third cooling zone and dusts and dehumidifies the third cooling zone. Multiple flow equalizing plates are arranged in both the first drying zone and the second drying zone. And for the ground source heat pump device and the solar heat pump device, the circulation pipelines associated with the two both pass through the first drying zone and are arranged opposite to the first circulation air duct, which ensures that the heat energy in the respective circulation pipelines of the ground source heat pump device and the solar heat pump device is not wasted, is used to heat the first drying zone, further avoids energy loss, and achieves an energy-saving effect.

[0076] In an embodiment of the present application, as Figure 2As shown in the wool processing flowchart of a geothermal energy-based wool drying device provided, where the first drying area is a closed space 2 meters long, i.e., the first drying section, the second drying area is also a closed space 2 meters long, i.e., the second drying section, the third cooling area is a closed space 2 meters long, i.e., the third cooling section, and the geothermal energy conversion device is a ground source heat pump device. Among them, the temperature threshold detected by the S4 temperature sensor is T1, the temperature and humidity thresholds detected by the S8 temperature and humidity sensor are T2 and ρ, and the temperature threshold detected by the S16 temperature sensor is T3. And T1 is 40 °C, T2 is 85 °C, and ρ is 15%. The preheating time of the first drying section is t1, and t1 is determined according to the determination of the S6 temperature sensor. The drying time of the second drying section is t2, and t2 is determined according to the temperature and humidity determined by S8. The time of the third cooling section is t3, and t3 should perform a certain degree of pretreatment on the wool before starting the drying program.

[0077] Based on this, S1 starts and enters step S2 to start the drying program; step S3 starts the heat energy conversion device and the dust removal and dehumidification device; if the S4 temperature sensor detects that the temperature T≥40°, it enters step S5 to input the wool into the first drying section for preheating; if the S6 temperature sensor detects that the temperature T≥80°, it enters S7 to input the wool into the second drying section for drying; at this time, the S8 temperature and humidity sensor starts to work to detect the temperature and humidity. If the detected temperature t<85°, the solar energy conversion device is turned on for heat energy supplement. If the detected humidity ρ>15%, S11 is also carried out to continue drying; if S13 determines that the humidity ρ<15% is satisfied, drying continues for 20 minutes. Then, the fan in the third section starts in S14, and S15 is carried out to convey the wool to the third cooling section. If the wool temperature T≤40° is detected in the cooling section, the wool is output and the drying program ends.

[0078] In summary, the geothermal energy conversion device and the dust removal and dehumidification device are used to preheat and purify the air, providing a suitable environment for drying. The drying process uses clean energy to protect the environment, solves problems such as unstable coal energy on the plateau, clarifies the drying process steps, shortens the wool drying time, and solves the problem of difficult wool drying in plateau areas.
