Description

Technical Field

[0001] This utility model belongs to the field of distillation equipment technology, specifically relating to an intelligent energy-saving distillation equipment that can be used for both grain distillation and alcohol distillation. Background Technology

[0002] Currently, energy-saving equipment for baijiu distillation typically recovers residual heat from the vapors by connecting a steam regeneration device to the outside of the still, and generates regenerated steam using a heat exchanger. This regenerated steam is then sent to the low-pressure end of a steam compressor, pressurized, and reused in the still, thus achieving heat recycling and reducing energy costs. However, this technology has significant shortcomings: baijiu distilleries need to use the same still for both grain steaming and baijiu distillation. While the energy-saving equipment effectively recovers heat from the vapors during the distillation stage, it is problematic during grain steaming. The steam contains grain impurities and volatile components, and direct recovery could contaminate the quality of the final baijiu. Therefore, to avoid cross-contamination, the still is usually left uncovered during grain steaming, allowing the steam to be directly released into the atmosphere, resulting in significant heat energy waste and hindering the efficient operation of the energy-saving equipment throughout the process. This limitation reduces overall heat recovery efficiency and increases production costs. Utility Model Content

[0003] The purpose of this invention is to overcome the problem that existing energy-saving distillation equipment for baijiu (Chinese liquor) cannot recover the heat generated during the grain steaming process, resulting in heat energy waste. This invention provides an intelligent energy-saving distillation equipment that can recover the heat generated during the grain steaming process, and can be used for both grain steaming and liquor distillation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This intelligent, energy-saving distillation equipment, capable of both steaming grains and distilling spirits, includes a steam regenerator, a still, a steam compressor, and a steam input module. The steam regenerator features an inner, separate waste steam cooling chamber and a spirit steam cooling chamber, as well as a steam regeneration chamber that exchanges heat with both chambers to generate regenerated steam. The waste steam cooling chamber has a waste steam inlet and a waste liquid outlet, while the spirit steam cooling chamber has a spirit steam inlet and a spirit liquid outlet. The steam regeneration chamber has a water inlet and a regenerated steam outlet. Both the waste steam inlet and the spirit steam cooling inlet are connected to a spirit steam delivery pipe. The still... The equipment includes an inner cooking chamber with a steam inlet and a distillation outlet connected to it. The steam inlet is selectively connected to either a waste steam delivery pipe or a liquor steam delivery pipe, depending on the process requirements, allowing the distillation equipment to be used for grain steaming or liquor distillation. The steam compressor has an inlet connected to a regenerated steam outlet and a compressed steam outlet. The compressed steam outlet is connected to the steam inlet of the still through a steam delivery pipe. The steam input module is connected to the steam delivery pipe and is used to supply steam to the cooking chamber of the still. The steam input module is equipped with a steam control valve to control the amount of steam input.

[0006] Compared with existing technologies, this utility model's intelligent energy-saving distillation equipment, which combines grain steaming and liquor distillation, features separate waste steam cooling chambers and liquor steam cooling chambers within the steam regenerator. This allows for independent recovery of waste steam from the grain steaming stage and liquor steam from the distillation stage, completely avoiding cross-contamination issues caused by shared recovery systems in traditional equipment. This ensures both the purity of the liquor and efficient heat recovery throughout the entire process. During both the grain steaming and distillation stages, waste steam containing impurities is cooled separately in the waste steam cooling chamber, recovering residual heat, while liquor steam undergoes efficient heat exchange in the liquor steam cooling chamber. This results in low-pressure regeneration in the steam regeneration chamber of the steam regenerator. Steam is then pressurized by a steam compressor before being supplied to the distillation still, ensuring a stable steam pressure in the still at different process stages. This reduces the need for external fresh steam replenishment and effectively recovers and utilizes heat, solving the energy waste problem of direct steam emission during grain steaming in traditional technology and reducing waste steam emissions. It saves 90% of the steam consumption in the cooking section of the grain steaming process. While retaining the functions of the traditional still, the equipment can be adapted to either grain steaming or distillation modes simply by switching pipelines, allowing the use of energy-saving distillation systems in both baijiu distillation and grain steaming processes, significantly improving production continuity and equipment economy.

[0007] Furthermore, it also includes a cooling device, which comprises a waste liquid cooling chamber and a wine liquid cooling chamber, as well as a coolant storage chamber for heat exchange with the waste liquid cooling chamber and the wine liquid cooling chamber. The waste liquid cooling chamber is provided with a waste liquid discharge outlet and a waste liquid cooling inlet connected to the waste liquid outlet. The wine liquid cooling chamber is provided with a wine liquid discharge outlet and a wine liquid cooling inlet connected to the wine liquid outlet. The coolant storage chamber is provided with a water inlet and a water outlet. It also includes a cooling water input module, which is connected to the water inlet through a cooling water control valve, and the water outlet is connected to the coolant storage chamber through a water supply pipe. The water inlet is connected, and the water supply pipe is equipped with a water supply valve to control its flow rate. With this setup, by adding a cooling device, waste liquid and wine liquid are introduced into separate waste liquid cooling chambers and wine liquid cooling chambers, respectively. The heat exchange between the waste liquid and the coolant storage chamber is used to further recover waste heat. At the same time, the cooled liquid can be reused as water supply in the steam regeneration chamber, forming a closed-loop energy-saving system. The linkage control between the cooling water input module and the water supply valve optimizes the cooling efficiency and water resource recycling rate, reducing energy consumption and wastewater discharge, and improving the overall sustainability of the equipment.

[0008] Furthermore, the coolant storage chamber includes a wastewater coolant storage chamber and a liquor coolant storage chamber arranged separately; the water inlet includes a wastewater cooling water inlet connecting to the wastewater coolant storage chamber and a liquor cooling water inlet connecting to the liquor coolant storage chamber. The wastewater cooling water inlet is connected to the cooling water input module sequentially through a wastewater cooling water inlet valve and the cooling water control valve, and the liquor cooling water inlet is connected to the cooling water input module sequentially through a liquor cooling water inlet valve and the cooling water control valve; the water outlet includes a wastewater cooling water outlet connecting to the wastewater coolant storage chamber and a liquor cooling water outlet connecting to the liquor coolant storage chamber, and the wastewater cooling water outlet and the liquor cooling water outlet are respectively connected to the water replenishment port. It also includes a cooling water recovery pipe, with the wastewater cooling water outlet and the beverage cooling water outlet respectively connected to the cooling water recovery pipe. The cooling water recovery pipe is equipped with a cooling water recovery valve to control its flow rate. By further subdividing the coolant storage chamber into a wastewater coolant storage chamber and a beverage coolant storage chamber, and equipping them with independent inlet valves, outlet valves, and cooling water recovery pipes, complete isolation of the waste liquid and beverage cooling systems is achieved, avoiding the risk of cross-contamination. At the same time, the cooling water can be flexibly selected for reuse in the steam regeneration chamber or recycled for reuse, further optimizing the efficiency of water and heat energy recycling, making the system operation more energy-efficient and environmentally friendly, and improving the accuracy and reliability of process control.

[0009] Furthermore, the wastewater coolant storage chamber is arranged around the periphery of the waste liquid cooling chamber, and the wine coolant storage chamber is arranged around the periphery of the wine cooling chamber; the waste liquid cooling chamber is located above the wine cooling chamber; or, the waste liquid cooling chamber is located below the wine cooling chamber. This arrangement, by surrounding the wastewater coolant storage chamber and the wine coolant storage chamber with their respective cooling chambers, forms a compact nested heat exchange structure, significantly improving cooling efficiency. Simultaneously, the waste liquid cooling chamber and the wine cooling chamber are arranged in a layered layout, saving equipment space and facilitating flexible adjustment of their relative positions according to process requirements, optimizing the synergy of the heat recovery process, and further enhancing the system's thermal energy utilization rate and operational stability.

[0010] Furthermore, a waste liquid thermometer is installed at the outlet of the waste liquid discharge port, and a wine liquid thermometer is installed at the outlet of the wine liquid discharge port. By setting up thermometers at the waste liquid discharge port and the wine liquid discharge port respectively, real-time monitoring of the discharge temperature of the waste liquid and the wine liquid is achieved, which facilitates precise control of the heat exchange efficiency of the cooling system. At the same time, the temperature data can be fed back to adjust the cooling water flow and water replenishment circulation, avoiding energy waste caused by overheating or overcooling, and further optimizing the stability and energy-saving effect of the heat recovery process.

[0011] Furthermore, the waste gas cooling chamber is arranged around the upper part of the alcohol vapor cooling chamber, and the steam regeneration chamber is arranged around the outer side of the waste gas cooling chamber and the lower part of the alcohol vapor cooling chamber. By arranging the alcohol vapor cooling chamber around the upper part of the waste gas cooling chamber and the steam regeneration chamber around the outer side of the alcohol vapor cooling chamber and the lower part of the waste gas cooling chamber, a stepped heat exchange structure is formed. This fully utilizes the natural convection effect of the rising high-temperature alcohol vapor and the sinking low-temperature waste vapor, significantly improving the heat recovery efficiency. At the same time, the compact three-dimensional layout optimizes the space utilization of the equipment, reduces heat loss, makes the steam regeneration process more efficient and stable, and further reduces the system's operating energy consumption.

[0012] Furthermore, the waste steam cooling chamber and the liquor steam cooling chamber have openings at the top. One end of the waste steam conveying pipe is sealed to the top opening of the waste steam cooling chamber, and the other end of the liquor steam conveying pipe is also sealed to the top opening of the liquor steam cooling chamber. The inner diameter of the liquor steam conveying pipe is larger than the outer diameter of the waste steam conveying pipe. The waste steam conveying pipe is placed inside the liquor steam conveying pipe, and the other end of the waste steam conveying pipe extends outward through the side of the liquor steam conveying pipe near the other end of the liquor steam conveying pipe. By nesting the waste steam conveying pipe inside the liquor steam conveying pipe and using a sealed fit structure with a top opening, an integrated design of the steam pipeline for the grain steaming and distillation processes is achieved. This saves equipment space and avoids external heat interference. At the same time, the large inner diameter design of the liquor steam conveying pipe ensures the independent flow of liquor steam and waste steam, preventing cross-contamination. The lateral extension structure of the waste steam pipe facilitates flexible connection to different process stages, significantly improving the system's compactness and ease of operation.

[0013] Furthermore, the vapor delivery pipe and the waste vapor delivery pipe are arranged side by side with intervals between them. By arranging the vapor delivery pipe and the waste vapor delivery pipe in a side-by-side and spaced manner, the two pipelines can operate independently and without interference, completely eliminating the risk of cross-contamination between the waste vapor from grain steaming and the vapor from distilling liquor. At the same time, this side-by-side layout facilitates the installation, maintenance, and temperature monitoring of the pipelines, improves the reliability and ease of operation of the system, and achieves efficient and stable operation of the heat recovery system while ensuring the purity of the liquor quality.

[0014] Furthermore, the top of the still is fitted with a still lid, and the distillation outlet is located on the still lid. The still lid is equipped with a first water seal device on the outer periphery of the distillation outlet. The waste steam conveying pipe or alcohol vapor conveying pipe is sealed to the distillation outlet through the first water seal device. With this arrangement, by setting the first water seal device on the outer periphery of the distillation outlet of the still lid, the waste steam conveying pipe or alcohol vapor conveying pipe is sealed to the distillation outlet, effectively preventing steam leakage and the entry of external air, and ensuring the airtightness and stability of the distillation process.

[0015] Furthermore, a second water seal device is provided on the outer periphery of the top opening of the waste vapor cooling chamber, and the waste vapor conveying pipe is sealed to the top opening of the waste vapor cooling chamber through the second water seal device; a third water seal device is provided on the outer periphery of the top opening of the liquor vapor cooling chamber, and the liquor vapor conveying pipe is sealed to the top opening of the liquor vapor cooling chamber through the third water seal device; with this arrangement, by setting the second and third water seal devices at the top openings of the waste vapor cooling chamber and the liquor vapor cooling chamber, a double-sealed connection is achieved between the waste vapor conveying pipe and the liquor vapor conveying pipe and the cooling chamber, effectively preventing steam leakage and external contamination, and ensuring the efficient and stable operation of the distillation system; at the same time, the water seal device has a simple and reliable structural design, is easy to install and maintain, improves the airtightness and efficiency of heat energy recovery, and further ensures the purity and safety of the liquor distillation process.

[0022] See Figures 1 to 4This utility model discloses an intelligent energy-saving distillation device for both grain steaming and liquor distillation, comprising a steam regenerator 3, a still 1, a steam compressor 5, and a steam input module 4. The steam regenerator 3 is equipped with a waste steam cooling chamber 31 and a liquor steam cooling chamber 32 arranged separately on the inner side, as well as a steam regeneration chamber 33 that exchanges heat with the waste steam cooling chamber 31 and the liquor steam cooling chamber 32 to generate regenerated steam.

[0023] Compared with existing technologies, this utility model's intelligent energy-saving distillation equipment, which combines grain steaming and liquor distillation, features a separate waste steam cooling chamber 31 and liquor steam cooling chamber 32 within the steam regenerator 3. This allows for the independent recovery of waste steam from the grain steaming stage and liquor steam from the liquor distillation stage, completely avoiding the cross-contamination problems caused by shared recovery systems in traditional equipment. This ensures the purity of the liquor and achieves efficient heat recovery throughout the entire process. During both the grain steaming and liquor distillation stages, waste steam containing impurities is cooled separately in the waste steam cooling chamber 31, recovering residual heat, while liquor steam undergoes efficient heat exchange in the liquor steam cooling chamber 32. This process regenerates the steam regeneration chamber 33 of the steam regenerator 3. The steam is converted into low-pressure regenerated steam, which is then pressurized by steam compressor 5 and supplied to the distillation still. This ensures that the still 1 obtains stable steam pressure at different process stages, while reducing the need for external fresh steam replenishment and effectively recovering and utilizing heat. This solves the energy waste problem of direct steam emission during grain steaming in traditional technology and reduces waste steam emissions, saving 90% of the steam consumption in the cooking section of the grain steaming process. While retaining the functions of the traditional still 1, the equipment can be adapted to either grain steaming or distillation mode simply by switching pipelines. This allows the use of an energy-saving distillation system in both the liquor distillation process and the grain steaming process, significantly improving production continuity and equipment economy.

[0024] See Figure 1 and Figure 2 In one embodiment, the system further includes a cooling device 6, which comprises a waste liquid cooling chamber 61, a wine liquid cooling chamber 62, and a coolant storage chamber for heat exchange with the waste liquid cooling chamber 61 and the wine liquid cooling chamber 62. The waste liquid cooling chamber 61 is provided with a waste liquid discharge port 611 and a waste liquid cooling inlet 613 connected to the waste liquid outlet 312 via a hot wastewater pipe 612. A cold wastewater pipe 614 is connected to the waste liquid discharge port 611. The wine liquid cooling chamber 62 is provided with a wine liquid discharge port 621 and a wine liquid cooling inlet 623 connected to the wine liquid outlet 322 via a hot wine liquid pipe 622. The coolant storage chamber is provided with an inlet and an outlet. The system also includes a cooling water input module 64, which is connected to the coolant storage chamber for heat exchange with the waste liquid cooling chamber 61 and the wine liquid cooling chamber 62. The cooling water control valve 65 is connected to the water inlet, and the water outlet is connected to the water supply port 331 through the water supply pipe 66. The water supply pipe 66 is equipped with a water supply valve 661 to control its flow rate. With this configuration, by adding the cooling device 6, the waste liquid and wine liquid are respectively introduced into the independent waste liquid cooling chamber 61 and wine liquid cooling chamber 62, and the waste heat is further recovered by utilizing the heat exchange with the coolant storage chamber. At the same time, the cooled liquid can be reused as water supply to the steam regeneration chamber 33, forming a closed-loop energy-saving system.

By further subdividing the coolant storage chamber into a wastewater coolant storage chamber 638 and a beverage coolant storage chamber, and equipping them with independent inlet valves, outlet valves, and cooling water recovery pipes 67, the waste liquid and beverage cooling systems are completely isolated, avoiding the risk of cross-contamination. At the same time, the cooling water can be flexibly selected for reuse in the steam regeneration chamber 33 for water replenishment or for recycling, further optimizing the efficiency of water and heat energy recycling, making the system operation more energy-efficient and environmentally friendly, and improving the accuracy and reliability of process control.

[0026] See Figure 1 and Figure 2 In one embodiment, the wastewater coolant storage chamber 638 is arranged around the outer periphery of the waste liquid cooling chamber 61, and the wine coolant storage chamber 639 is arranged around the outer periphery of the wine coolant cooling chamber 62; the waste liquid cooling chamber 61 is located on the upper side of the wine coolant cooling chamber 62; or, the waste liquid cooling chamber 61 is located on the lower side of the wine coolant cooling chamber 62.

At the same time, the compact three-dimensional layout optimizes the space utilization of the equipment, reduces heat loss, makes the steam regeneration process more efficient and stable, and further reduces the system's operating energy consumption.

[0029] See Figure 1 and Figure 2 See Figure 1 In this embodiment, the exhaust gas cooling chamber 31 and the alcohol vapor cooling chamber 32 have openings at the top. One end of the exhaust gas conveying pipe 37 is sealed to the top opening of the exhaust gas cooling chamber 31, and one end of the alcohol vapor conveying pipe 36 is sealed to the top opening of the alcohol vapor cooling chamber 32.

The exhaust gas conveying pipe 37 is placed inside the alcohol vapor conveying pipe 36, and the other end of the exhaust gas conveying pipe 37 passes through the alcohol vapor conveying pipe 36 near the other end of the alcohol vapor conveying pipe 36. The side extends outward; by nesting the waste steam conveying pipe 37 inside the alcohol steam conveying pipe 36 and adopting a top-opening sealed fit structure, the integrated design of the steam pipeline for the grain steaming and distillation processes is realized, which saves equipment space and avoids external heat interference; at the same time, the large inner diameter design of the alcohol steam conveying pipe 36 ensures the independent flow of alcohol steam and waste steam, preventing cross-contamination, while the lateral extension structure of the waste steam pipe facilitates flexible access to different process links, significantly improving the system's compactness and ease of operation.

[0030] In an alternative embodiment, the vapor delivery pipe 36 and the waste vapor delivery pipe 37 are arranged side by side with a gap between them. By arranging the vapor delivery pipe 36 and the waste vapor delivery pipe 37 in a side-by-side and spaced manner, the two pipes can operate independently and without interference, completely eliminating the risk of cross-contamination between the waste vapor from grain steaming and the vapor from distilling liquor. At the same time, this side-by-side layout facilitates the installation, maintenance, and temperature monitoring of the pipes, improves the reliability and ease of operation of the system, and achieves efficient and stable operation of the heat recovery system while ensuring the purity of the liquor.

[0031] See Figure 1 and Figure 2 In one embodiment, the top of the still 1 is fitted with a still cover 11, and the distillation outlet 23 is located on the still cover 11. The still cover 11 is provided with a first water seal device (not shown) on the outer periphery of the distillation outlet 23. The waste steam conveying pipe 37 or the alcohol vapor conveying pipe 36 is sealed to the distillation outlet 23 through the first water seal device.

[0033] In one embodiment, the first water seal device, the second water seal device, and the second water seal device are water seal devices for water-sealing connections between pipes in the prior art. For example, one end of one pipe is provided with a water-filling U-shaped groove, and the end of the other pipe is inserted into the U-shaped groove for water sealing.

[0034] See Figures 1 to 3The intelligent energy-saving distillation equipment of this utility model, which can be used for both grain steaming and liquor distillation, includes the following working processes when using the liquor distillation process:

[0035] The vapor delivery pipe 36 is connected to the distillation outlet 23 of the still 1, so that the still 1 is connected to the steam regenerator 3. The steam input module 4 generates steam, which enters the still 1 through the steam delivery pipe 41 to heat the mash. The steam control valve 43 is adjusted according to the steam pressure sensor 42 to control the amount of steam within the preset range. Then, alcohol vapor is generated in the still 1, and enters the alcohol vapor cooling chamber 32 of the steam regenerator 3 through the alcohol vapor delivery pipe 36. It exchanges heat with the water in the steam regeneration chamber 33. After the water temperature sensor 35 reaches the set value, the steam output valve 53 and the regeneration steam valve 39 open, and the steam compressor 5 starts, so that a low-pressure environment is formed on the water side of the steam regeneration chamber 33. The water boils in the low-pressure environment to generate regeneration steam, which is sent to the steam compressor 5 through the regeneration steam pipe 38. After being pressurized, it forms recovered steam, which enters the still 1 through the regeneration steam output pipe 54. Due to the recovery steam, the steam pressure sensor 42 detects the pressure increase and reduces the opening of the steam control valve 43 to keep the pressure within the set value. The opening of the steam control valve 43 gradually decreases as the recovered steam increases until it is completely closed. The operating frequency of the steam compressor 5 is automatically adjusted according to the steam control valve 43 to keep the pressure within the set value.

[0036] In the vapor cooling chamber 32 of the steam regenerator 3, the vapor turns into condensed liquid due to heat transfer and enters the liquid cooling chamber 62 of the cooling device 6 through the hot liquid pipe 622. The cooling water control valve 65 and the liquid cooling inlet 632 are opened, and the cooling water input module 64 delivers cooling water into the liquid cooling liquid storage chamber 639 of the cooling device 6, where it exchanges heat with the liquid in the liquid cooling chamber 62. After the liquid is cooled, it is delivered to the liquid collection container through the liquid discharge port 621. A liquid thermometer 682 is installed at the liquid discharge port 621 to control the opening of the liquid cooling water inlet valve 634 to control the amount of cooling water, so that the outlet temperature reaches the set value.

[0037] As the water in the steam regeneration chamber 33 boils and evaporates, the water level sensor 34 detects a value lower than the lower limit setting value, the water supply valve 661 opens, and the cooling water recovery valve 671 closes. The heated cooling water in the wine coolant storage chamber 639 enters the steam regeneration chamber 33 through the water supply pipe until the water level sensor 34 detects a value higher than the upper limit setting value. Then, the cooling water recovery valve 671 opens, the water supply valve 661 closes, and the cooling water in the wine coolant storage chamber 639 is sent to the cooling water collection container through the cooling water recovery pipe 67.

[0038] See Figure 1 , Figure 2 and Figure 4The present invention relates to an intelligent energy-saving distillation device that can be used for both grain steaming and alcohol distillation. When using the grain steaming process, the intelligent energy-saving distillation device includes the following working process:

[0039] Waste steam delivery pipe 37 is connected to the distillation outlet 23 of still 1, connecting still 1 to steam regenerator 3. Steam input module 4 generates steam, which enters still 1 through steam delivery pipe 41 to heat the mash. Steam control valve 43 is adjusted according to steam pressure sensor 42 to control the steam volume within a preset range. This generates alcohol vapor in still 1, which enters the waste steam cooling chamber 31 of steam regenerator 3 through waste steam delivery pipe 37, exchanging heat with the water in the steam regeneration chamber 33. When water temperature sensor 35 reaches the set value, steam output valve 53 and regeneration steam valve 39 open, and steam compressor 5 starts. A low-pressure environment is formed on the water side of the steam regeneration chamber 33. The water boils under low pressure to generate regenerated steam, which is sent to the steam compressor 5 through the regenerated steam pipe 38. After being pressurized, it becomes recovered steam and enters the steam pot 1 through the regenerated steam output pipe 54. Due to the presence of recovered steam, the steam pressure sensor 42 detects the pressure increase and reduces the opening of the steam control valve 43 to keep the pressure within the set value. The opening of the steam control valve 43 gradually decreases as the recovered steam increases until it is completely closed. The operating frequency of the steam compressor 5 is automatically adjusted according to the steam control valve 43 to keep the pressure within the set value.

[0040] In the exhaust steam cooling chamber 31 of the steam regenerator 3, the exhaust steam becomes condensed waste liquid due to heat transfer, and enters the waste liquid cooling chamber 61 of the cooling device 6 through the hot waste water pipe 612. The cooling water control valve 65 and the beverage cooling water inlet 632 are opened, and the cooling water input module 64 delivers cooling water into the waste liquid storage chamber of the cooling device 6 to exchange heat with the waste liquid in the waste liquid cooling chamber 61. After the waste liquid is cooled, it is delivered to the waste liquid collection container through the waste liquid discharge port 611. A waste liquid thermometer 681 is installed at the waste liquid discharge port 611 to control the opening of the waste water cooling water inlet valve 633 to control the cooling water flow rate so that the waste water outlet temperature reaches the set value.

[0041] As the water in the steam regeneration chamber 33 boils and evaporates, the water level sensor 34 detects a value lower than the lower limit setting value, the water supply valve 661 opens, and the cooling water recovery valve 671 closes. The cooling water heated in the waste liquid coolant storage chamber enters the steam regeneration chamber 33 through the water supply pipe until the water level sensor 34 detects a value higher than the upper limit setting value. Then, the cooling water recovery valve 671 opens, the water supply valve 661 closes, and the cooling water in the waste liquid coolant storage chamber is sent to the cooling water collection container through the cooling water recovery pipe 67.
