[0054] Example

[0055] See also Figure 1 , Figure 2 and Figure 3 This embodiment provides a Zhenjiu waste heat utilization system, which is used to utilize the waste heat of wine vapor in the Zhenjiu system.

[0056] The waste heat utilization system of Zhenjiu includes a primary condenser 100, a secondary condenser 200, a first cooling circulation subsystem 300, a second cooling circulation subsystem 400 and an absorption refrigeration subsystem 500. The primary condenser 100 and the secondary condenser 200 are arranged in series, wherein the primary condenser 100 is used to connect with the wine vapor outlet in the Zhenjiu system; the secondary condenser 200 is connected with the wine liquid outlet of the primary condenser 100; the first cooling circulation subsystem 300 is connected with the primary condenser 100 and used for heat exchange with the primary condenser 100; the second cooling circulation subsystem 400 is connected with the secondary condenser 200 and used for heat exchange with the primary condenser 100; the absorption refrigeration subsystem 500 is connected with the first cooling circulation subsystem 300 and the second cooling circulation subsystem 400.

[0057] In this embodiment, the first cooling cycle subsystem 300 is used to provide a heat source required for refrigeration for the absorption refrigeration subsystem 500 , and the absorption refrigeration subsystem 500 is used to provide air conditioning refrigeration and to dissipate heat for the second cooling cycle subsystem 400 .

[0058] The Zhenjiu waste heat utilization system provided in this embodiment cools the high-temperature wine vapor in the Zhenjiu system through the first-stage condenser 100 and the second-stage condenser 200 in sequence, and the first cooling circulation subsystem 300 exchanges heat with the high-temperature wine vapor, and then provides a heat source for the absorption refrigeration subsystem 500, and the absorption refrigeration subsystem 500 provides air-conditioning refrigeration, and at the same time provides heat dissipation for the second cooling circulation subsystem 400, and the second cooling circulation subsystem 400 exchanges heat with the second-stage condenser 200. In this way, stepped heat dissipation is achieved through two-stage cooling, which further reduces the wine output temperature and increases the wine output. At the same time, the waste heat of the wine vapor is reasonably utilized to achieve air-conditioning refrigeration, which greatly saves electricity and water resources.

[0059] In order to more clearly describe the technical solution of the present application, the following is a description of the Zhenjiu waste heat utilization system provided in this embodiment, as follows:

[0060] Please participate Figure 2 The first cooling circulation subsystem 300 includes a heat preservation water tank 310, a first water supply pipeline 320, a first water return pipeline 330 and a first circulating water pump 340. The heat preservation water tank 310 is used to store medium-temperature water; one end of the first water supply pipeline 320 is connected to the water outlet of the heat preservation water tank 310, and the other end is connected to the first cooling water inlet of the primary condenser 100. One end of the first water return pipeline 330 is connected to the first cooling water outlet of the primary condenser 100, and the other end is connected to the absorption refrigeration subsystem 500 and the heat preservation water tank 310 in sequence. The first water return pipeline 330 is used to transport heat source to the absorption refrigeration subsystem 500. The first circulating water pump 340 is arranged on the first water supply pipeline 320.

[0061] In this way, the first circulating water pump 340 operates to transport the medium-temperature water stored in the thermal insulation water tank 310 to the primary condenser 100 through the first water supply pipeline 320 and perform heat exchange in the primary condenser 100, and then output high-temperature water to enter the first return water pipeline 330 and input into the absorption refrigeration subsystem 500, thereby providing a heat source for the absorption refrigeration subsystem 500. After the absorption refrigeration subsystem 500 uses the high-temperature water, it is converted into medium-temperature water and then transported back to the thermal insulation water tank 310 for storage.

[0062] It can be understood that the first cooling circulation subsystem 300 is a closed circulation system, which achieves the goals of constant temperature, water saving, energy saving and clean production.

[0063] In some embodiments, the first cooling circulation subsystem 300 further includes a first cooling tower 350 and a first heat exchanger 360. The primary side of the first heat exchanger 360 is connected to the first cooling tower 350 through the first cooling water circulation pipeline 370, and the number of the first cooling tower 350 is more than one. The first cooling water circulation pipeline 370 is provided with a first cooling water pump 371, and the secondary side of the first heat exchanger 360 is installed in parallel on the first return water pipeline 330 through the water supply branch pipeline 380. In this way, when the absorption refrigeration subsystem 500 is not running or running at a low load, the cooling water circulation in the first cooling water circulation pipeline 370 can be driven by the first cooling water pump 371, and then the first heat exchanger 360 and the high-temperature water transported by the water supply branch pipeline 380 are exchanged for heat, and then the first cooling tower 350 is used to dissipate heat, thereby taking away the heat in the first return water pipeline 330, so as to maintain the normal operation of the second cooling circulation subsystem 400 and the primary condenser 100. At the same time, the heat dissipation mode of the first heat exchanger 360 can also cope with some emergencies, such as failure or maintenance of the absorption refrigeration subsystem 500.

[0064] Further, a controllable switching valve 380 is respectively provided on the water supply branch pipeline 380 and the corresponding first return water pipeline 330 in parallel. In this way, the first heat exchanger 360 can be selected to participate in the heat exchange work through the switching valve 380. Optionally, the switching valve 380 can be selected as a solenoid valve, an electric butterfly valve, an electric ball valve or a manual valve.

[0065] See also Figure 2 The absorption refrigeration subsystem 500 includes an absorption refrigeration main unit 510, a second cooling tower 520 and an air conditioning terminal 530. The absorption refrigeration main unit 510 is connected to the first return water pipeline 330 in the first cooling cycle subsystem 300. The absorption refrigeration main unit 510 is a hot water type lithium bromide absorption refrigerator. The lithium bromide absorption refrigerator can use a heat source for cooling or for heating. In this embodiment, the lithium bromide absorption refrigerator uses a heat source for cooling as an example.

[0066] At least one second cooling tower 520 is provided, and the second cooling tower 520 is connected to the absorption refrigeration main unit 510 through a second cooling water circulation pipeline 540, and a second cooling water pump 550 is provided on the second cooling water circulation pipeline 540. In this way, when the second cooling water pump 550 is in operation, the heat generated during the operation of the absorption refrigeration main unit 510 can be transported to the second cooling tower 520 through the cooling water in the second cooling water circulation pipeline 540, and the heat is dissipated through the second cooling tower 520, thereby taking away the heat in the absorption refrigeration main unit 510.

[0067] The number of air conditioning terminals 530 can be arranged in multiples. The air conditioning terminal 530 is connected to the absorption refrigeration host 510 through the cold water circulation pipeline 560, and the absorption refrigeration host is used to provide a cold source for the air conditioning terminal 530. Specifically, a cold water pump 570 is provided on the cold water circulation pipeline 560. The cold water pump 570 drives the air-conditioned cold water in the cold water circulation pipeline 560 to transport the cold produced by the absorption refrigeration host 510 during operation to the air conditioning terminal 530, and then the fan and coil of the air conditioning terminal 530 exchange heat with the environment where the air conditioning terminal 530 is located, thereby providing cooling.

[0068] Furthermore, the cold water circulation pipeline 560 is also used to exchange heat with the second cooling circulation subsystem 400. In this way, the air-conditioned cold water in the cold water circulation pipeline 560 can also take away the heat in the second cooling circulation subsystem 400, thereby ensuring the normal operation of the secondary condenser 200.

[0069] In this embodiment, the first cooling circulation subsystem 300 and the absorption refrigeration subsystem 500 can share a cooling tower, that is, the first cooling water circulation pipeline 370 and the second cooling circulation pipeline are connected to a cooling tower, which can be the first cooling tower 350 or the second cooling tower 520. This saves cost investment and reduces production costs. Further, the water inlet and outlet of the absorption refrigeration main unit 510 can be connected through the bypass branch pipe 390 to bypass the absorption refrigeration main unit 510, so that the high-temperature water in the first return water pipeline 330 directly passes through the bypass branch pipe 390 and then enters the first heat exchanger 360. In this way, when the absorption refrigeration main unit 510 is fault-checked, the bypass branch pipe 390 can be opened for bypass, and then the water inlet and outlet of the absorption refrigeration main unit 510 can be cut off by a valve, and the heat is dissipated through the first heat exchanger 360 in the first cooling circulation subsystem 300.

[0070] In some embodiments, the first cooling tower 350 and the second cooling tower 520 may also be retained, and both the first cooling tower 350 and the second cooling tower 520 may dissipate heat for the first radiator and the absorption refrigeration host 510. In addition, the first cooling tower 350 and the second cooling tower 520 may be used alternately or simultaneously under high load to ensure the heat dissipation effect and the normal operation of the equipment.

[0071] See also Figure 2 and Figure 3 The second cooling circulation subsystem 400 includes a second heat exchanger 410, a second water supply pipeline 420, a second water return pipeline 430 and a second circulating water pump 440. The secondary side of the second heat exchanger 410 is connected to the cold water circulation pipeline 560 of the absorption refrigeration subsystem 500; one end of the second water supply pipeline 420 is connected to the water outlet of the second heat exchanger 410 on the primary side, and the other end is connected to the second cooling water inlet of the secondary condenser 200; one end of the second water return pipeline 430 is connected to the water inlet of the second heat exchanger 410 on the primary side, and the other end is connected to the second cooling water outlet of the secondary condenser 200; the second circulating water pump 440 is arranged on the second water supply pipeline 420 or the second water return pipeline 430. In this way, the second circulating water pump 440 is operated to drive the cooling water in the second cooling circulation subsystem 400 to flow, enter the secondary condensation, and exchange heat with the wine liquid coming out of the primary condenser 100, further reducing the temperature of the wine liquid. The cooling water after heat exchange enters the second heat exchanger 410 to exchange heat with the cold water in the cold water circulation pipeline 560, and the cold water in the cold water circulation pipeline 560 cools down the second cooling circulation subsystem 400, further increasing the wine output. It can be seen that the second cooling circulation subsystem 400 is a closed circulation system.

[0072] Furthermore, the Zhenjiu waste heat utilization system also includes a filter module 600, which is arranged on the pipeline connecting the primary condenser 100 and the wine vapor outlet. Among them, a first pressure detector 630 is arranged between the filter module 600 and the primary condenser 100. The filter module 600 includes two detachable filters 610 arranged in parallel, and each detachable filter 610 is provided with a maintenance valve 620 at its inlet and outlet.

[0073] Optionally, a first pressure detector 630 is provided at the outlet of each detachable filter 610. In this way, the pressure information of the first pressure detector 630 can be used to determine whether the corresponding filter is clogged. In addition, two detachable filters 610 arranged in parallel can be used to maintain one of them without affecting the normal operation of the other. The two detachable filters 610 can be used alternately.

[0074] See also Figure 2 and Figure 3 In this embodiment, the wine outlet of the primary condenser 100 is provided with a second pressure detector 110, and the wine outlet of the secondary condenser 200 is also provided with a third pressure detector 210. Similarly, the pressure information of the second pressure detector 110 can be used to determine whether the primary condenser 100 is blocked. The pressure information of the first pressure detector 630 and the second pressure detector 110 can be used to determine whether the secondary condenser 200 is blocked. When blockage occurs, it needs to be cleaned in time.

[0075] In some embodiments, a first temperature sensor 640 is further provided at the water outlet of the detachable filter 610, a second temperature sensor 120 is provided at the wine outlet of the primary condenser 100, and a third temperature sensor 220 is also provided at the wine outlet of the secondary condenser 200. In this way, the temperature change of the wine is monitored in real time through the first temperature sensor 640, the second temperature sensor 120 and the third temperature sensor 220.

[0076] Furthermore, a first proportional regulating valve 321 is provided on the first water supply pipeline 320, and a second proportional regulating valve 421 is provided on the second water supply pipeline 420. In this way, the heat exchange capacity of the primary condenser 100 can be adjusted by controlling the first proportional regulating valve 321 in linkage with the temperature information of the first temperature sensor 640, and the heat exchange capacity of the secondary condenser 200 can be controlled in linkage with the temperature information of the second temperature sensor 120.

[0077] In some embodiments, the Zhenjiu waste heat utilization system further includes an automatic water replenishment subsystem 700, which is connected to the first cooling circulation subsystem 300 and / or the second cooling circulation subsystem 400 and / or the absorption refrigeration subsystem 500. In this embodiment, the automatic water replenishment subsystem 700 is connected to the first cooling circulation subsystem 300, the second cooling circulation subsystem 400 and the absorption refrigeration subsystem 500 to achieve automatic water replenishment.

[0078] Specifically, the automatic water replenishment subsystem 700 includes an expansion water tank 710, which is connected to an external water supply pipeline, such as tap water. The expansion water tank 710 is connected to at least one of the second water supply pipeline 420 of the second cooling circulation subsystem 400 and the cold water circulation pipeline 560 in the absorption refrigeration subsystem 500 through a water replenishment pipeline 720.

[0079] Optionally, the first cooling circulation subsystem 300 is replenished with water through an external water pipe of the thermal insulation water tank 310, wherein a float valve is provided at the water replenishment port of the thermal insulation water tank 310 to realize automatic water replenishment.

[0080] Furthermore, the water transported by the external water pipe of the insulated water tank 310 is softened.

[0081] Optionally, a softening water processor may be provided on the pipeline of the expansion water tank 710, so that water can be replenished through the softening water processor to soften the replenished water.

[0082] See also Figure 1 , Figure 2 and Figure 3 The following is an example of a wine system producing wine vapor above 95°C:

[0083] Specifically, wine vapor above 95°C passes through the detachable filter 610 and enters the primary condenser 100 to exchange heat with the 55°C medium-temperature circulating water in the insulated water tank 310 to obtain 60°C wine liquid. The 55°C medium-temperature water reaches 90°C after heat exchange through the primary condenser 100. The 90°C hot water can provide a driving heat source for the absorption refrigeration host 510 through the first return water pipeline 330. The 90°C hot water is used by the absorption refrigeration host 510 (hot water type lithium bromide absorption refrigerator) and then returns to the insulated water tank 310 at 55°C. The absorption refrigeration main unit 510 generates 7°C cold water which is supplied to the air-conditioning terminal 530 for refrigeration, and also supplies the second heat exchanger 410. The 7°C cold water is heat exchanged through the air-conditioning terminal 530 and the second heat exchanger 410 to obtain 12°C cold water which is returned to the absorption refrigeration main unit 510. After the second cooling circulation subsystem 400 exchanges heat in the second heat exchanger 410, circulating cold water of about 20°C is obtained to supply the secondary condenser 200, so that the 60°C wine is further cooled to about 35°C. The pressure information of the first pressure sensor, the second pressure sensor and the third pressure sensor are monitored to determine whether the detachable filter 610, the primary condenser 100 and the secondary condenser 200 need to be cleaned. Among them, two detachable filters 610 are used alternately and can be disassembled and cleaned without stopping production to ensure the normal operation of the system; the first proportional regulating valve 321 is controlled by the temperature linkage of the second temperature sensor 120 to adjust the heat exchange rate of 55°C hot water in the first-stage condenser 100, and the second proportional regulating valve 421 is controlled by the temperature linkage of the third temperature sensor 220 to control the heat exchange rate of the second-stage condenser 200 according to the required wine outlet temperature; the insulated water tank 310 ensures a stable supply of system water when the amount of wine changes. For example, when the amount of wine decreases or the absorption refrigeration host 510 fails, the water is bypassed through the bypass branch pipe 390 and then through the first heat exchanger 360 for heat exchange and then dissipated by the corresponding cooling tower to cool the high-temperature water in the first return water pipeline 330 to meet the cooling needs of the wine; the control of the first heat exchanger 360 is controlled by the valve changer.

[0084] The waste heat utilization system for wine making provided in this embodiment greatly reduces the amount of tap water used and sewage treatment during wine making. The waste heat from wine making is used for refrigeration and process heating, thereby improving energy utilization, improving the quality of wine, achieving a wine output temperature of less than 35°C, and increasing the wine output by 30%.
