Description

Technical Field

[0001] The present invention belongs to the field of cooling technology, and in particular relates to a cooling device and a cooling control method and device. Background Art

[0002] At present, there are two main cooling methods. The first method is to use normal temperature tap water to spray and cool the high temperature target to be cooled. The second method is to place the high temperature target to be cooled in a water tank for rapid cooling. Among them, the first method uses normal temperature tap water, which absorbs less heat, resulting in increased water consumption and low water energy utilization rate. Moreover, the waste heat generated by normal temperature tap water when it encounters the high temperature target to be cooled cannot be utilized, and the thermal energy utilization rate is low. The second method cannot meet the needs of long-term cooling. Moreover, as the cooling time gradually increases, the impurities in the water tank also gradually increase, affecting the cooling effect. At the same time, for large high temperature targets to be cooled, there is also the problem of inconvenience in placing them in the water tank and taking them out of the water tank after cooling.

When cooling water meets the high-temperature target to be cooled, the high-temperature water vapor generated condenses on the heat exchange surface of generator 2, and the higher-temperature heat is released to the inside of generator 2 through the heat exchange surface.

[0090] The first end and the second end of the heat exchange device are respectively connected to the generator 2, and are used to convert the gaseous refrigerant generated by the generator 2 into a liquid refrigerant and return it to the generator 2; here, the heat exchange device realizes the recycling of the refrigerant;

[0091] The third end of the heat exchange device is connected to the spraying device 1, and the fourth end is connected to the water tank 3, which is used to cool the wastewater recovered from the water tank 4 to obtain cooling water, and then transport it to the spraying device 1; here, the heat exchange device can recover the heat generated by the cooling water when it encounters a high-temperature target to be cooled, and transfer the heat to the refrigerant, and further cool and reduce the pressure of the refrigerant, exchange heat with the wastewater, absorb the heat of the wastewater, convert the wastewater into cooling water, and further transport it to the spraying device 1 for spraying again, thereby realizing the recycling of wastewater and improving energy utilization.

[0092] It should be noted that the various components in the cooling device according to the embodiment of the present invention are connected via connecting pipes.

[0093] In the embodiment of the present invention, the cooling equipment includes a spraying device 1, a generator 2, a heat exchange device and a water storage tank 3; the spraying device 1 sprays cooling water to the target to be cooled to reduce water consumption and improve the cooling effect, and the generator 2 is used to spray the cooling water to the target to be cooled. The water vapor generated is condensed to recover the waste heat, and the heat exchange device is used to convert the gaseous refrigerant generated by the generator into a liquid refrigerant and return it to the generator 2, and the waste water recovered from the water storage tank 3 is cooled to obtain cooling water, and is transported to the spraying device 1, so as to realize the waste heat utilization and waste water recycling, thereby improving the energy utilization rate and accelerating the cooling process.

[0094] Optionally, the heat exchange device comprises:

[0095] The evaporator 4 is connected to the spraying device 1 and the water storage tank 3 respectively, and stores liquid refrigerant for cooling the waste water recovered from the water storage tank 3 to obtain cooling water, and then transporting the cooling water to the spraying device 1 .

[0096] Here, the end of the evaporator 4 connected to the spraying device 1 is the third end of the heat exchange device, and the end of the evaporator 4 connected to the water storage tank 3 is the fourth end of the heat exchange device.

[0097] It should be noted that the liquid refrigerant exchanges heat with the wastewater in the evaporator 4 , absorbs the heat of the wastewater, and the liquid refrigerant absorbs heat and evaporates to be converted into a gaseous refrigerant. The wastewater is cooled to obtain cooling water that is transported to the spraying device 1 .

[0098] Optionally, the heat exchange device further comprises:

[0099] A condenser 5 and an expansion valve 6 connected to the condenser 5;

[0100] The condenser 5 is connected to the generator 2 and is used to convert the gaseous refrigerant generated by the generator 2 into a liquid refrigerant and transport it to the expansion valve 6;

[0101] The expansion valve 6 is connected to the evaporator 4 and is used to reduce the pressure and temperature of the liquid refrigerant delivered by the condenser 5 and deliver it to the evaporator 4 .

[0102] Here, the end of the condenser 5 connected to the transmitter 2 is the first end of the heat exchange device.

[0103] It should be noted that the high-pressure and high-concentration liquid refrigerant in the generator 2 absorbs the heat of the high-temperature water vapor, and most of it is converted into a high-temperature, high-pressure and high-concentration gaseous refrigerant, and a small part is converted into a low-concentration liquid refrigerant. Among them, the high-temperature, high-pressure and high-concentration gaseous refrigerant is sent to the condenser 5 through the connecting pipeline, and heat exchanges with the air in the condenser 5. The high-temperature, high-pressure and high-concentration gaseous refrigerant releases heat and is converted into a low-temperature liquid refrigerant, which is transported to the expansion valve 6, and is further cooled and reduced in the expansion valve 6, and converted into a low-temperature and low-pressure liquid refrigerant, which is transported to the evaporator 4.

[0104] The low-temperature and low-pressure liquid refrigerant exchanges heat with the wastewater in the evaporator 4, absorbs the heat of the wastewater, and the low-temperature and low-pressure liquid refrigerant absorbs heat and evaporates to be converted into a low-pressure gaseous refrigerant.

[0105] Optionally, the heat exchange device further comprises:

[0106] Throttle valve 7, absorber 8 and solution pump 9;

[0107] The throttle valve 7 is connected to the generator 2 and the absorber 8 respectively, and is used to reduce the pressure of the liquid refrigerant that has not produced the gaseous refrigerant in the generator 2, and transport it to the absorber 8;

[0108] The absorber 8 is connected to the throttle valve 7, the evaporator 4 and the solution pump 9 respectively, and is used for absorbing the gaseous refrigerant produced by the evaporator 4 with the liquid refrigerant delivered by the throttle valve 7, and delivering the liquid refrigerant to the solution pump 9;

[0109] The solution pump 9 is connected to the absorber 8 and the generator 2 respectively, and is used to increase the pressure of the liquid refrigerant delivered by the absorber 8 and deliver it to the generator 2.

[0110] Here, the two ends where the throttle valve 7 and the solution pump 9 are respectively connected to the generator 2 are the second ends of the heat exchange device.

[0111] It should be noted that the high-pressure and high-concentration liquid refrigerant in the generator 2 absorbs the heat of the high-temperature water vapor, and most of it is converted into a high-temperature, high-pressure and high-concentration gaseous refrigerant, and a small part is converted into a low-concentration liquid refrigerant, among which the low-concentration liquid refrigerant is sent to the throttle valve 7 through the connecting pipeline, and is throttled and reduced in the throttle valve 7 before being sent to the absorber 8, which absorbs the low-pressure gaseous refrigerant in the evaporator 4, converts it into a low-pressure and high-concentration liquid refrigerant, and transports it to the solution pump 9, and finally increases the pressure in the solution pump 9, converts it into a high-pressure and high-concentration liquid refrigerant, and sends it back to the generator 2 through the connecting pipeline.

[0112] Optionally, the cooling device further comprises:

[0113] The water pump 10 is disposed between the water storage tank 3 and the fourth end of the heat exchange device, and is used to pressurize the wastewater recovered from the water storage tank 3 and transport it to the heat exchange device.

[0114] It should be noted that the water pump 10 pressurizes the waste water recovered from the water storage tank 3 and then sends it to the heat exchange device.

[0115] When the heat exchange device includes the evaporator 4 , the water pump 10 pressurizes the waste water and sends it into the cooling pipeline of the evaporator 4 to perform heat exchange with the liquid refrigerant stored in the heat exchange pipeline of the evaporator 4 .

[0116] Alternatively, if Figure 2 As shown, the cooling device also includes:

[0117] The filter 11 is disposed between the water storage tank 3 and the fourth end of the heat exchange device, and is used to filter the metal residues in the waste water recovered from the water storage tank 3 .

[0118] Here, when the target to be cooled is a high-temperature metallurgical product, the cooling water sprayed onto the surface of the metallurgical product will bring the metal residue into the water storage tank 3. The filter 11 is provided with an electromagnetic adsorption device, which can use a specific high-frequency electric field or magnetic field to filter the metal residue in the wastewater, thereby improving the purity of the cooling water, saving water, and protecting the environment to a certain extent.

[0119] Optionally, the cooling device further comprises:

[0120] The transmission device 12 is disposed between the spraying device 1 and the water storage tank 3, and is used to transmit the target to be cooled from the first area of ​​the transmission device 12 to the spraying area, and then from the spraying area to the second area.

[0121] Here, the area between the first area and the second area of ​​the transmission device is a spraying area, corresponding to the spraying range of the spraying device 1 .

[0122] It should be noted that the rolling parts provided in the transmission device 12 can uniformly transmit the target to be cooled, and achieve a consistent cooling effect through uniform transmission and uniform spraying within the spraying range of the spraying device 1. Moreover, the transmission device 12 solves the problem of inconvenience in manually taking and placing large targets to be cooled.

[0123] Alternatively, if Figure 3 As shown, the cooling device also includes:

[0124] Fan 13 and air cooling and drying nozzle 14;

[0125] The first connecting pipeline between the fan 13 and the air-cooling drying nozzle 14 is arranged in the heat exchange device;

[0126] The fan 13 is used to provide air, which is converted into cold air in the first connecting pipeline and transported to the air-cooling drying nozzle 14;

[0127] The air-cooling drying nozzle 14 is disposed above the second region of the transmission device 12 and is used to spray cold air toward the object to be cooled.

[0128] Here, the high-temperature dry air is transported to the first connecting pipeline through the fan 13, and the first connecting pipeline is arranged in the heat exchange device. Specifically, when the heat exchange device includes an evaporator 4, the first connecting pipeline is arranged in the evaporator 4. The high-temperature dry air exchanges heat with the refrigerant in the evaporator 4, and the refrigerant evaporates and absorbs heat. The high-temperature dry air is converted into cold air and transported to the air-cooled drying nozzle 14 through the second connecting pipeline.

[0129] When the target to be cooled leaves the spraying range of the spraying device 1 and enters the second area of ​​the transmission device 12, the air-cooling drying nozzle 14 arranged above the second area can spray cold air to the target to be cooled to further cool it down and remove the residual moisture on the surface of the target to be cooled.

[0130] It should be noted that, in order to spray the cold air evenly, the air-cooling drying nozzle 14 can be designed as a ring structure.

[0131] It should also be noted that the cooling equipment provided in the embodiment of the present invention can recover the waste heat of high-temperature water vapor, improve energy utilization, and perform heat-driven refrigeration at the same time. The generated cold energy can quickly cool the recovered wastewater, improve the utilization rate of cooling water, and reduce water consumption. At the same time, the temperature of the cooling water is lower than that of tap water at normal temperature, which increases the heat exchange capacity of the product to be cooled, is conducive to rapid cooling, and improves the cooling effect.

[0132] like Figure 4 As shown, an embodiment of the present invention further provides a cooling control method, which is applied to a controller, and the controller is connected to the cooling device as described above, and the method includes:

[0133] Step 401, when it is detected that the target to be cooled is located below the spraying device, the spraying device is controlled to spray cooling water toward the target to be cooled;

[0134] It should be noted that the spraying device is controlled to evenly spray cooling water onto the surface of the target to be cooled. Compared with tap water at room temperature, cooling water can effectively increase the heat exchange capacity and accelerate the cooling process.

[0135] Step 402, after the first preset time of spraying cooling water, control the heat exchange device to convert the gaseous refrigerant generated by the generator into liquid refrigerant to flow back to the generator, and cool the wastewater recovered from the water tank to obtain cooling water, and transport it to the spraying device.

[0136] It should be noted that the high-temperature water vapor generated by spraying cooling water on the target to be cooled adheres to the heat exchange surface of the generator, and the heat exchange device is controlled to recover the heat of the water vapor and perform heat-driven refrigeration. The generated cold energy quickly cools down the recovered wastewater, which not only realizes waste heat recovery but also wastewater utilization, greatly improving energy utilization.

[0137] Specifically, the heat exchange device includes an evaporator, a condenser, an expansion valve, a throttle valve, an absorber and a solution pump, which controls the high-pressure and high-concentration liquid refrigerant in the generator to absorb the heat of high-temperature water vapor, and converts most of it into high-temperature, high-pressure and high-concentration gaseous refrigerant, and a small part into low-concentration liquid refrigerant;

[0138] Among them, the high-temperature, high-pressure, and high-concentration gaseous refrigerant is sent to the condenser through the connecting pipeline, and heat is exchanged with the air in the condenser. The high-temperature, high-pressure, and high-concentration gaseous refrigerant releases heat and is converted into a low-temperature liquid refrigerant and is transported to the expansion valve. The temperature and pressure are further reduced in the expansion valve, and it is converted into a low-temperature, low-pressure liquid refrigerant and is transported to the evaporator.

[0139] The low-temperature and low-pressure liquid refrigerant exchanges heat with the wastewater in the evaporator, absorbs the heat of the wastewater, and the low-temperature and low-pressure liquid refrigerant absorbs heat and evaporates to be converted into a low-pressure gaseous refrigerant;

[0140] The low-concentration liquid refrigerant is sent into the throttle valve through the connecting pipeline, and then sent into the absorber after throttling and reducing pressure in the throttle valve. It absorbs the low-pressure gaseous refrigerant in the evaporator and converts it into a low-pressure and high-concentration liquid refrigerant, which is then transported to the solution pump. Finally, the solution pump is controlled to increase the pressure, converting the low-pressure and high-concentration liquid refrigerant into a high-pressure and high-concentration liquid refrigerant, which is then sent back to the generator through the connecting pipeline.

[0141] In the embodiment of the present invention, cooling water is sprayed onto the target to be cooled by a spraying device, so as to reduce water consumption and improve cooling effect. The water vapor generated after the cooling water is sprayed onto the target to be cooled by a generator is condensed to recover waste heat of the water vapor. At the same time, a heat exchange device is used to convert the gaseous refrigerant generated by the generator into a liquid refrigerant which flows back to the generator. The waste water recovered from the water storage tank is cooled to obtain cooling water and transported to the spraying device, so as to realize waste heat utilization and waste water recycling, thereby improving energy utilization and accelerating the cooling process.

[0142] Optionally, the method further comprises:

[0143] After the second preset time period of spraying cooling water, the water pump is started to pressurize the waste water recovered from the water storage tank and transport it to the heat exchange device.

[0144] It should be noted that the water pump is controlled to start and provide pressure to transport the recovered wastewater to the heat exchange device.

[0145] Optionally, the method further comprises:

[0146] After the third preset time period of spraying the cooling water, the filter is controlled to filter the metal residues in the waste water recovered from the water storage tank.

[0147] It should be noted that when the filter is provided with an electromagnetic adsorption device, the filter is started to filter out metal residues in the recovered waste water, thereby improving the purity of the cooling water and saving water.

[0148] Optionally, when it is detected that the target to be cooled is located below the spraying device, before controlling the spraying device to spray cooling water toward the target to be cooled, the method further includes:

[0149] The transmission device is controlled to transmit the target to be cooled from the first area of ​​the transmission device to the spraying area within a fourth preset time period.

[0150] It should be noted that before controlling the spraying of cooling water, the transmission device is controlled to transmit the target to be cooled to the spraying area, waiting for the spraying device to spray cooling water.

[0151] Optionally, the method further comprises:

[0152] Within a fifth preset time period of spraying cooling water, the transmission device is controlled to transmit the target to be cooled from the spraying area of ​​the transmission device to the second area.

[0153] It should be noted that within the fifth preset time period of spraying cooling water, the transmission device is controlled to transmit the target to be cooled from the spraying area of ​​the transmission device to the second area, waiting for the air-cooling drying nozzle to spray cold air.

[0154] Optionally, the method further comprises:

[0155] After the sixth preset time period of spraying cooling water, starting the fan;

[0156] When it is detected that the object to be cooled is transferred to the second area of ​​the transfer device, the air-cooling drying nozzle is controlled to spray cold air toward the object to be cooled.

[0157] It should be noted that the fan is started to evaporate and absorb heat in the heat exchange device to convert the high-temperature dry air into cold air, and the air-cooled drying nozzle is controlled to spray.

[0158] It should also be noted that the above-mentioned first preset time length, second preset time length, third preset time length, fourth preset time length, fifth preset time length and sixth preset time length can be set according to control logic timing, experience value or experimental value.

[0159] like Figure 5 As shown, an embodiment of the present invention further provides a cooling control device, comprising:

[0160] The first control module 501 is used to control the spraying device to spray cooling water to the target to be cooled when it is detected that the target to be cooled is located below the spraying device;

[0161] The second control module 502 is used to control the heat exchange device to convert the gaseous refrigerant generated by the generator into liquid refrigerant and return it to the generator after the first preset time of spraying cooling water, and to cool the wastewater recovered from the water storage tank to obtain cooling water and transport it to the spraying device.

[0162] In the embodiment of the present invention, cooling water is sprayed onto the target to be cooled by a spraying device, so as to reduce water consumption and improve cooling effect.
