Description

Technical Field

[0001] The present application relates to the field of warehouse storage technology, and in particular to a low-carbon emission reduction internal and external double-circulation insulated grain storage warehouse. Background Art

[0002] Low-temperature grain storage is a recognized green grain storage technology in modern storage technology. This technology is generally implemented in grain storage warehouses. When storing grain, existing grain storage warehouses generally use natural cold sources in low-temperature seasons or artificial cold sources such as grain coolers to cool the grain piles in the warehouse, so that the overall average grain temperature in the warehouse is lower than 15°C, so that low temperatures can be used to delay grain aging and inhibit the occurrence of insects and mildew.

[0003] However, in high temperature and high humidity ecological grain storage areas, the ambient temperature in summer will rise to above 35℃ and last for a long period of time. In such a high temperature environment, the walls of the warehouse will transfer a large amount of heat into the warehouse, causing the temperature of the grain close to the wall to rise, forming a "cold heart and hot skin" effect, which will cause the grain close to the wall to mold and insect pests, endangering the food safety in the warehouse.

[0004] In view of this, it is necessary to provide a low-carbon emission reduction internal and external double-circulation insulated grain storage warehouse. Summary of the invention

[0009] By adopting the above technical solution, when sunlight shines on the outer wall, the air in the outer air layer will be heated, and the heated air will move upward and leave the outer air layer from the air outlet, so as to form a negative pressure in the outer air layer, so that the outside air can be sucked into the outer air layer through the natural wind vents on the ground and form an airflow in the outer air layer, so that the heat in the outer air layer can be taken away by the flowing air, thereby reducing the heat transferred from the outer air layer to the inner wall.

[0013] By adopting the above technical scheme, after leaving the air outlet of the intelligent temperature control system on the wall of the warehouse, the cold air will first enter the multiple circulating air ducts connected to the air outlet, then enter the ventilation duct connected to the circulating air duct, and enter the circulating air duct along the ventilation duct into the circulating air duct connected to the air inlet of the intelligent temperature control system on the wall of the warehouse, and finally return to the intelligent temperature control system on the wall of the warehouse along the circulating air duct, thereby forming a circulating low-temperature airflow in the heat exchange channel to reduce the temperature of the inner wall, thereby ensuring that the temperature of the grain in the containing cavity close to the inner wall does not exceed the low-temperature grain storage requirements.

[0033] Figure 1 This is a schematic diagram of a low-carbon emission reduction internal and external double-circulation insulated grain storage warehouse of the present application, in which the solid arrows indicate the airflow direction in the heat exchange channel. Figure 2 This is a schematic cross-sectional view of a low-carbon emission reduction internal and external double circulation insulated grain storage warehouse in the present application taken along the horizontal direction. Figure 1 and Figure 2, a low-carbon emission reduction internal and external double-circulation insulated grain storage warehouse, comprising an outer wall 1, an inner wall 2 and an intelligent temperature control system 3 for the inner wall of the warehouse, an outer air interlayer 7 is formed between the outer wall 1 and the inner wall 2, so as to reduce the heat transfer between the outer wall 1 and the inner wall 2, and an external circulation can be further formed in the outer air interlayer 7 to prevent heat accumulation; a accommodating cavity suitable for storing grain is formed in the inner wall 2, the inner wall 2 comprises an inner wall top 21 and an inner wall body 22, a heat exchange channel 23 is formed inside the inner wall body 22, the intelligent temperature control system 3 for the inner wall of the warehouse can be a dedicated central air conditioner for the warehouse, the dedicated central air conditioner for the warehouse comprises an outlet duct, an inlet duct and a temperature probe of the inner wall of the warehouse, the outlet duct of the dedicated central air conditioner for the warehouse is connected to the inlet side of the heat exchange channel 23, and the inlet duct of the dedicated central air conditioner for the warehouse is connected to the outlet side of the heat exchange channel 23, so as to be able to transfer cold air from the heat exchange While the air inlet side of the channel 23 is input into the inner wall 22, the hot air in the heat exchange channel 23 is drawn back from the air outlet side of the heat exchange channel 23 to the warehouse dedicated central air conditioner. The wall temperature probe in the warehouse can monitor the temperature of the inner wall 22 and feed back the monitoring result to the warehouse dedicated central air conditioner, so that the warehouse dedicated central air conditioner can adjust its own operating power according to the monitoring result, speed up the output of cold air when the monitoring result is higher than the predetermined temperature value, and slow down the output of cold air when the monitoring result is lower than the predetermined temperature value, so that the temperature of the inner wall 22 can be maintained at the predetermined temperature value, and the predetermined temperature value can be set to a temperature not higher than the temperature required for low-temperature grain storage, so as to ensure that the temperature of the grain near the inner wall 22 in the accommodating cavity does not exceed the low-temperature grain storage requirements, for example, the average grain temperature of the stored grain is required to be lower than 15°C, and the local maximum temperature does not exceed 20°C, then the wall temperature should be controlled to be no more than 20°C. The above-mentioned warehouse dedicated central air conditioner belongs to the prior art and will not be repeated here.

[0034] See also Figure 1 and Figure 2 The outer wall 1 includes an outer wall body 11 and an outer wall top 12. A ground natural wind vent 111 is provided at the wall root of the outer wall body 11. The ground natural wind vent 111 is connected to the outer air interlayer 7. An air outlet 121 is provided on the outer wall top 12. The air outlet 121 is connected to the outer air interlayer 7. It can be understood that when sunlight irradiates the outer wall 1, the air in the outer air interlayer 7 will be heated, and the heated air will move upward and leave the outer air interlayer 7 from the air outlet 121, so that negative pressure can be formed in the outer air interlayer 7, so that the relatively low temperature air from the outside can be sucked into the outer air interlayer 7 through the ground natural wind vent 111 and air flow can be formed in the outer air interlayer 7, so that the heat in the outer air interlayer 7 can be taken away by the flowing air, so that it is not easy to accumulate heat in the outer air interlayer 7, thereby reducing the heat transferred from the outer air interlayer 7 to the inner wall 2.

[0035] See also Figure 1and Figure 2 In one embodiment, a low-carbon emission reduction internal and external double-circulation heat-insulated grain storage warehouse also includes an underground pipe 4, one end of which is connected to the ground natural wind vent 111, and the other end of which is located on the ground surface. The pipe body of the underground pipe 4 is buried underground, so that the air entering the outer air interlayer 7 from the ground natural wind vent 111 will first pass through the underground pipe 4. Since the underground temperature is relatively low, the temperature of the air can be reduced, so that the heat in the outer air interlayer 7 can be better taken away. Specifically, a filter can be set in the port at one end of the underground pipe 4 away from the ground natural wind vent 111, so that the underground pipe 4 is not easy to absorb external debris into itself to cause blockage; the opening of the port can also be designed to face the ground, so as to ensure that rainwater will not enter the underground pipe 4 from the port to cause blockage.

[0036] Preferably, the buried pipe 4 can also be arranged to pass through a rainwater drainage network before being connected to the external air interlayer 7. For example, the buried pipe 4 can be passed through an inspection well, and indirect heat exchange can be achieved between the rainwater in the inspection well and the air in the buried pipe 4, so that the air in the buried pipe 4 can be cooled through the rainwater drainage network, thereby reducing the temperature of the air entering the external air interlayer 7, so as to better take away the heat in the external air interlayer 7.

[0037] See also Figure 1 and Figure 2 The heat exchange channel 23 includes a plurality of ventilation ducts 232 formed inside the inner wall 22 along the horizontal direction and a plurality of circulation air ducts 231 buried in the inner wall 22 along the vertical direction. At least one ventilation duct 232 is formed in the inner wall 22 between two adjacent circulation air ducts 231, and the two adjacent circulation air ducts 231 and the ventilation duct 232 between the two circulation air ducts 231 form a group of heat exchange units. An air outlet corresponding to the number of the plurality of heat exchange units is provided on the air outlet duct of the warehouse-specific central air conditioner, and an air inlet corresponding to the number of the plurality of heat exchange units is provided on the air inlet duct of the warehouse-specific central air conditioner. One of the two circulation air ducts 231 in the heat exchange unit is connected to the corresponding air outlet, and the other of the two circulation air ducts 231 in the heat exchange unit is connected to the corresponding air inlet.

[0038] It can be understood that after leaving the air outlet duct of the warehouse-dedicated central air conditioner, the cold air will first enter the multiple circulating air ducts 231 connected to the air outlet duct, and then enter the ventilation duct 232 connected to the circulating air duct 231, and along the ventilation duct 232 enter the circulating air duct 231 connected to the air inlet duct of the warehouse-dedicated central air conditioner, and finally return to the warehouse-dedicated central air conditioner along the circulating air duct 231, so that a circulating low-temperature airflow can be formed in the heat exchange channel 23, so as to reduce the temperature of the inner wall 22, thereby ensuring that the temperature of the grain in the accommodating cavity close to the inner wall 22 does not exceed the low-temperature grain storage requirements.

[0039] Figure 3 yes Figure 2 Schematic enlarged view of area A in FIG, showing the card slot. Figure 1 and Figure 3 In one embodiment, the inner wall 22 includes a plurality of prefabricated columns 221 and a plurality of inner wall panels 222. Two slots 2211 are provided on the prefabricated columns 221 in the vertical direction. A plug-in channel is formed between the corresponding slots 2211 on two adjacent prefabricated columns 221. The inner wall panels 222 can be inserted into the plug-in channel and plug-in with the slots 2211. An installation gap is formed between the inner wall panels 222 and the bottom of the slots 2211. The circulating air duct 231 is installed in the installation gap, so that the circulating air duct 231 and the ventilation duct 232 can be combined to form a heat exchange unit by first installing the inner wall panels 222 in the plug-in channel to form an installation gap, and then installing the circulating air duct 231 into the installation gap, thereby facilitating the assembly of the heat exchange unit. Specifically, the inner wall panel 222 can adopt SP prestressed hollow panels, so that the existing cavity in the SP prestressed hollow panels can be used as the ventilation duct 232 inside the inner wall panel 222. There is no need to process the ventilation duct 232 inside the inner wall panel 222, thereby reducing the amount of engineering work when constructing an internal and external double-circulation insulated grain storage warehouse.

[0040] See also Figure 1A low-carbon emission reduction internal and external dual-circulation insulated grain storage warehouse also includes an internal warehouse adjustment component 5, a grain condition detection component 6 and a controller (not shown in the figure). The internal warehouse adjustment component 5, the grain condition detection component 6 and the controller can be combined with the intelligent temperature control system 3 on the wall of the warehouse to form an intelligent temperature and humidity control system to achieve intelligent adjustment of the temperature and humidity of the grain in the warehouse. Specifically, the regulating component 5 in the warehouse can adjust the temperature and humidity of the grain in the containing chamber, the grain condition detection component 6 can detect the temperature and humidity of the grain in the containing chamber, and the grain condition detection component 6 is electrically connected to the controller and can send the detection result to the controller, the controller is electrically connected to the regulating component 5 in the warehouse, and can control the opening or closing of the regulating component 5 in the warehouse according to the received detection result; when the controller finds that either the temperature or humidity of the grain detected by the grain condition detection component 6 exceeds the range required for low-temperature grain storage, the controller will control the regulating component 5 in the warehouse to open, so as to restore the temperature and humidity of the grain in the containing chamber to the range required for low-temperature grain storage. The above-mentioned range of low-temperature grain storage requirements can be: the average grain temperature of the grain is lower than 15°C, the local maximum temperature does not exceed 20°C, and the humidity is not higher than 15%; when the controller finds that the temperature and humidity of the grain detected by the grain condition detection component 6 are both maintained within the range required for low-temperature grain storage, the controller will control the regulating component 5 in the warehouse to close, thereby realizing automatic adjustment of the grain condition in the containing chamber.

[0041] Specifically, the grain condition detection component 6 includes a temperature sensor 61 and a humidity sensor 62. The temperature sensor 61 can use an optical fiber temperature sensor, and the humidity sensor 62 can be a sensor made of a humidity-sensitive resistor. The optical fiber temperature sensor and the humidity sensor 62 are both arranged on the wall of the inner wall 22 on one side close to the storage cavity, and the optical fiber temperature sensor and the humidity sensor 62 are both electrically connected to the controller so as to be able to synchronously detect the temperature and humidity of the grain in the storage cavity and feed back the detection data to the controller; the warehouse adjustment component 5 includes a warehouse refrigeration device 51 and a ground ventilation cage 52. The warehouse refrigeration device 51 can be a warehouse-specific air conditioner, which is electrically connected to the controller, and the ground ventilation cage 52 is arranged on the storage cavity. The bottom of the storage cavity is connected to a dedicated air conditioner for the warehouse. The dedicated air conditioner for the warehouse can inhale the air above the grain in the storage cavity, and then transmit the cold air to the ground ventilation cage 52 after cooling the inhaled air. The ground ventilation cage 52 can make the cold air evenly enter the grain pile, so as to achieve the cooling of the grain; the dedicated air conditioner for the warehouse includes a dehumidification module (which can be a heat exchange plate of the air conditioner, which can condense the moisture in the air into droplets in the cooling state to achieve dehumidification). The dehumidification module can reduce the humidity of the cold air output by the dedicated air conditioner for the warehouse. When it is necessary to reduce the humidity in the storage cavity, the dehumidification module will reduce the humidity of the cold air output by the dedicated air conditioner for the warehouse, so as to replace the air with higher humidity in the warehouse, so as to dehumidify the storage cavity. The above-mentioned dedicated air conditioner for the warehouse with dehumidification function belongs to the prior art and will not be repeated here.

[0042] Specifically, a photovoltaic power generation panel (not shown in the figure) is laid on the outer wall top 12 to prevent the outer wall top 12 from being directly exposed to sunlight, thereby improving the thermal insulation performance of the outer wall top 12 and providing electricity for the internal and external double-circulation thermal insulation grain storage warehouse, making the internal and external double-circulation thermal insulation grain storage warehouse more economical and energy-saving; see Figure 2 On the outer wall 11, a heat insulation layer 112 is also provided on the wall near the inner wall 22. The heat insulation layer 112 can be a heat insulation aluminum foil to reduce the heat transfer between the outer wall 1 and the outer air interlayer 7, thereby improving the heat insulation performance of the inner and outer double circulation heat insulation grain storage warehouse; the outer wall 11 can also adopt ALC board (i.e., autoclaved lightweight concrete) with good heat insulation performance to further improve the heat insulation performance of the inner and outer double circulation heat insulation grain storage warehouse; the above-mentioned heat insulation design for the outer wall 11 can reduce the outer wall The heat transferred from the outer wall body 11 to the outer air interlayer 7 is transferred to the outer wall body 11, so that when the sunlight irradiates and heats the outer wall top 12 and the outer wall body 11 at the same time, the air in the outer air interlayer 7 that contacts the outer wall top 12 absorbs more heat than the air that contacts the outer wall body 11, thereby enabling a greater thermal pressure difference to be created between the air below the outer air interlayer 7 and the air above it, so that the airflow speed formed in the outer air interlayer 7 is faster and the chimney effect is more significant, thereby being able to take away more heat from the outer air interlayer 7 through the airflow.

[0043] The working principle of the low-carbon emission reduction internal and external double-circulation insulated grain storage warehouse in this application is as follows:

[0044] An outer wall 1, an inner wall 2 and an intelligent temperature control system 3 for the inner wall of the warehouse are provided, an outer air interlayer 7 is formed between the outer wall 1 and the inner wall 2 to reduce the heat transfer between the outer wall 1 and the inner wall 2, and an external circulation can be further formed in the outer air interlayer 7 to prevent heat accumulation; a storage cavity suitable for storing grain is formed in the inner wall 2, the inner wall 2 includes an inner wall top 21 and an inner wall body 22, a heat exchange channel 23 is formed inside the inner wall body 22, and the intelligent temperature control system 3 for the inner wall of the warehouse includes an air outlet and an air inlet, the air outlet is connected to the air inlet side of the heat exchange channel 23, and the air inlet is connected to the air outlet side of the heat exchange channel 23, so that the intelligent temperature control system 3 for the inner wall of the warehouse can input cold air into the heat exchange channel 23 through the air outlet, and draw hot air out of the heat exchange channel 23 through the air inlet, so as to reduce the temperature of the inner wall body 22, thereby ensuring that the temperature of the grain near the inner wall body 22 in the storage cavity does not exceed the low-temperature grain storage requirement.

[0045] The outer wall 1 includes an outer wall body 11 and an outer wall top 12. A ground natural wind vent 111 is opened at the root of the outer wall body 11, and the ground natural wind vent 111 is connected to the outer air interlayer 7. An air outlet 121 is opened on the outer wall top 12, and the air outlet 121 is connected to the outer air interlayer 7. When the air in the outer air interlayer 7 is heated, the hot air will move upward and leave the outer air interlayer 7 from the air outlet, so that negative pressure can be formed in the outer air interlayer 7, so that the outside air can be sucked into the outer air interlayer 7 through the ground natural wind vent 111 and airflow can be formed in the outer air interlayer 7, so that the heat in the outer air interlayer 7 can be taken away by the flowing air, thereby reducing the heat transferred from the outer air interlayer 7 to the inner wall 2.
