Description

Technical Field

[0001] This utility model relates to the field of low-energy-consumption cooling technology in winter, and in particular to a low-energy-consumption cooling device for winter. Background Technology

[0002] The reaction of calcium carbide with water to produce acetylene is an exothermic process. To control the reaction rate, prevent localized overheating, and avoid excessively high acetylene gas temperatures, an effective cooling system is needed to ensure the equipment and process operate at a safe and stable temperature. Cooling water at 5°C provides sufficient cooling capacity to ensure that critical equipment such as reactors, gas scrubbing towers, and cooling towers operate at a safe and stable low temperature. Therefore, configuring an independent 5°C cooling water system for the acetylene process is a common and necessary engineering design. Its main purpose is to ensure the stability of the reaction process, improve gas purity, ensure safe equipment operation, and prevent major accidents such as fires and explosions.

[0003] However, in winter, due to the low ambient temperature, the cooling demand of some processes is reduced, resulting in a cooling capacity demand that is far less than the minimum output capacity of the ice machine. Therefore, there are fewer energy-consuming devices, the ice machine is often idle, and surge reduces the service life of the ice machine. Furthermore, long-term operation poses a risk of equipment damage, and the equipment maintenance costs are high, resulting in high operating costs. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of reduced cooling demand, frequent idling of ice machines, reduced equipment lifespan, and increased operating costs during winter, and to propose a low-energy-consumption cooling device for winter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A low-energy-consumption cooling device for winter includes a chilled water buffer tank, an air cooler, and a condensate tank. The outlet of the chilled water buffer tank is connected to an installation pipe, the first outlet of the installation pipe is connected to a first connecting pipe, the outlet of the first connecting pipe is connected to a first inlet of the air cooler, the outlet of the air cooler is connected to a delivery pipe, and the outlet of the condensate tank is connected to a second inlet of the air cooler.

[0006] By using a condensate tank and an air cooler, the water in the condensate tank is at a low temperature in winter. The water in the condensate tank is then transferred to the air cooler to cool the chilled water in the chilled water buffer tank, eliminating the need for a refrigeration unit and protecting the refrigeration unit.

[0007] Preferably, a first self-regulating valve is provided on the first connecting pipe.

[0008] Depending on the needs of use, the first or second automatic control valve can be closed or opened. Depending on the temperature used in winter, chilled water can also be supplied to the chiller unit, which will cool the chilled water to prevent the outside temperature from being too high in winter and failing to meet the cooling requirements.

[0009] Preferably, a pressure gauge, a temperature gauge, and a flow meter are connected sequentially to the delivery pipe.

[0010] Preferably, an air-cooled fan is installed above the refrigeration unit.

[0011] Air-cooled fans cool the chilled water in the air cooler.

[0012] Preferably, the air cooler is equipped with a spray system, and the second outlet of the air cooler is connected to a circulation pump, the outlet of which is connected to the spray system.

[0013] A circulating pump draws water from the air cooler and delivers it to a spray system, which cools the chilled water.

[0014] Preferably, the third outlet of the installation pipe is connected to a circulation pipe, and the outlet of the circulation pipe is connected to the chilled water buffer tank.

[0015] Preferably, the first inlet of the chilled water buffer tank is connected to an inlet pipe, and the second inlet of the chilled water buffer tank is connected to a return pipe.

[0016] Compared with the prior art, the beneficial effects of this utility model are: by cooperating with the condensate tank and the air cooler, the water in the condensate tank is cooled in winter, and the cooled production water cools the chilled water supplied to the air cooler. There is no need to use the refrigeration unit, and the refrigeration unit can be shut down to protect it. Furthermore, the refrigeration unit and the condensate tank can be used in combination according to the winter temperature conditions to ensure that the equipment that needs to be cooled operates at a safe and stable temperature.

[0020] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0021] Reference Figure 1A low-energy-consumption cooling device for winter includes a chilled water buffer tank 1, an air cooler 15, and a condensate tank 6. The air cooler 15 has two media channels. Production water from the condensate tank 6 is supplied to the chilled water buffer tank 1 through these channels. An installation pipe is connected to the outlet of the chilled water buffer tank 1, and a circulation pipe 3 is connected to the third outlet of the installation pipe. The circulation pipe 3 balances the pressure within the overall pipeline. The outlet of the circulation pipe 3 is connected to the chilled water buffer tank 1. A water inlet pipe 2 is connected to the first inlet of the chilled water buffer tank 1, and a water return pipe 7 is connected to the second inlet. The water return pipe 7 is connected to equipment requiring cooling. Used chilled water is returned to the chilled water buffer tank 1. The condensate tank 6 contains residual production water. This water is supplied to the condensate tank 6, which is then placed outdoors. When the outdoor temperature is low, the water in the condensate tank 6 is cooled before being supplied to the air cooler 15. The air cooler 15 is connected to a first connecting pipe 16, the outlet of which is connected to the first inlet of the air cooler 15. The chilled water in the chilled water buffer tank 1 is transported to the air cooler 15 through the first connecting pipe 16. The air cooler 15 cools the chilled water in the chilled water buffer tank 1 through the condensate tank 6. Since the temperature is low in winter, the water temperature in the condensate tank 6 is also low, which can cool the chilled water in the chilled water buffer tank 1 to meet the requirements. At this time, the refrigeration unit 4 can be completely shut down, and the operation of the refrigeration unit 4 is not required, which protects the refrigeration unit 4, improves its service life, and saves the enterprise's production costs. The refrigeration unit 4 includes ice machines, and different numbers of ice machines are set according to the requirements during use. The outlet of the air cooler 15 is connected to a conveying pipe 13. The air cooler 15 transports the cooled chilled water to the conveying pipe 13, and the conveying pipe 13 transports the cooled chilled water to the location that needs to be cooled during acetylene production. A pressure gauge 8, a temperature gauge 9, and a flow meter 10 are sequentially connected to the delivery pipe 13. A first automatic control valve 17 is installed on the first connecting pipe 16. The outlet of the condensate tank 6 is connected to the second inlet of the air cooler 15. A second connecting pipe 18 is connected to the second outlet of the installation pipe and is connected to the inlet of the chiller unit 4. The outlet of the chiller unit 4 is connected to the delivery pipe 13 through the outlet pipe 19. During use, the temperature of the chilled water in the delivery pipe 13 is monitored. When the temperature of the chilled water in the delivery pipe 13 is high, the second automatic control valve 21 on the second connecting pipe 18 is opened. A filter 20 is connected to the second connecting pipe 18. The chilled water in the chilled water buffer tank 1 is... The chilled water in the chilled water buffer tank 1 is cooled by the second connecting pipe 18. After cooling, the chilled water is sent to the delivery pipe 13 through the outlet pipe 19, thereby reducing the required temperature of the chilled water. At this time, the flow rate of the air cooler 15 needs to be controlled. When the temperature of the two mixtures passes the temperature detection gauge 9, if it still does not meet the standard, the first automatic control valve 17 on the first connecting pipe 16 is closed, and the second automatic control valve 21 on the outlet pipe 19 and the second connecting pipe 18 is opened. At this time, all the chilled water in the chilled water buffer tank 1 is sent to the chiller unit 4. The ice machine in the chiller unit 4 cools the chilled water in the chilled water buffer tank 1, and then sends it to the delivery pipe 13 through the outlet pipe 19.

[0022] Reference Figure 1 An air-cooled fan 14 is installed above the refrigeration unit 4. When the highest temperature is below -10℃, only two air-cooled fans 14 and circulating pump 11 are needed for cooling to meet process requirements. After the air cooler is put into operation, when the highest temperature is above -10℃, the operation is gradually increased to three air-cooled fans 14 and circulating pump 11 to meet process requirements. A spray system 12 is installed inside the air cooler 15. The second outlet of the air cooler 15 is connected to the circulating pump 11, and the outlet of the circulating pump 11 is connected to the spray system 12. When the chilled water buffer... When the chilled water in tank 1 is supplied to the air cooler 15, the air-cooled fan 14 cools the chilled water in the air cooler 15. At the same time, the circulating pump 11 extracts the water supplied from the condensate tank 6 to the air cooler 15 and supplies it to the spray system 12. The spray system 12 sprays the water to cool the chilled water supplied from the chilled water buffer tank 1 again, thereby quickly reducing the temperature of the chilled water supplied to the delivery pipe 13. This facilitates cooling of the required locations later, improves cooling efficiency, and reduces the use of the refrigeration unit 4.

[0023] The operation method of a low-energy-consumption cooling device in winter includes the following steps: S1: When the outdoor temperature is low in winter, the temperature of the condensate tank 6 is low. The condensate tank 6 supplies production water to the air cooler 15. At the same time, the first automatic control valve 17 is opened. The chilled water buffer tank 1 supplies chilled water to the air cooler 15 through the chilled water pump 5 and the first connecting pipe 16. The production water cools the chilled water. S2: At the same time, the air-cooled fan 14 cools down the chilled water in the air cooler 15, and the circulating pump 11 draws the production water from the air cooler 15 and delivers the production water to the spray system 12, which cools down the chilled water again. S3: The cooled chilled water is delivered to the delivery pipe 13, and the delivery pipe 13 delivers the water to the equipment that needs to be cooled during acetylene production; S4: Temperature sensor 9 on delivery pipe 13 detects the delivery temperature. When the temperature of chilled water does not meet expectations, the second automatic control valve 21 on the second connecting pipe 18 and the outlet pipe 19 is opened. S5: At this time, the chilled water in the chilled water buffer tank 1 will also be transported to the chiller unit 4 through the second connecting pipe 18. The chiller unit 4 cools the chilled water. The cooled chilled water is then transported to the conveying pipe 13 through the outlet pipe 19. The conveying pipe 13 transports the chilled water to the equipment that needs to be cooled during acetylene production. S6: When the temperature detection gauge 9 on the delivery pipe 13 detects that the temperature of the chilled water is still not as expected, the first automatic control valve 17 is closed. At this time, all the chilled water in the chilled water buffer tank 1 is delivered to the chiller unit 4 through the second connecting pipe 18. The chiller unit 4 cools down the chilled water. The cooled chilled water is delivered to the delivery pipe 13 through the outlet pipe 19. The delivery pipe 13 delivers the chilled water together to the equipment that needs to be cooled during acetylene production. S7: Then, the outdoor temperature is detected. When the outdoor temperature is below -10℃, the second automatic control valve 21 is closed and the first automatic control valve 17 is opened, and the chilled water is sent to the air cooler 15 again.
