Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Before explaining the embodiments of the present application in detail, the application scenarios related to the embodiments of the present application are explained first.
At present, a natural gas loop system can recycle natural gas, and is important equipment for measuring the flow rate of the natural gas. In the process of detecting the natural gas flow, that is, in the operation process of the natural gas loop system, the outlet of a component in the natural gas loop system, such as a loop compressor, usually generates a higher temperature. When the temperature exceeds a certain threshold, the operation of the natural gas loop system may be affected, and the detection of the natural gas flow is inaccurate.
Based on such application scenarios, the embodiments of the present application provide a cooling apparatus for a natural gas loop system, which is capable of controlling each component in the natural gas loop system in a stable temperature environment.
After the application scenario of the embodiment of the present application is described, a cooling device of a natural gas loop system provided by the embodiment of the present application will be described in detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a cooling device of a natural gas loop system according to an embodiment of the present application, and referring to fig. 1, the cooling device includes: the temperature control system comprises a temperature control unit 1, a water storage device 2, a water supply device 3, a temperature control water pipe 4 and a component to be cooled 5, wherein the component to be cooled 5 is surrounded by the temperature control water pipe 4.
The first end 11 of the temperature adjusting unit 1 is connected with the first end 21 of the water storage device 2, the second end 22 of the water storage device 2 is connected with the first end 31 of the water supply device 3, the second end 32 of the water supply device 3 is connected with the first end 41 of the temperature adjusting water pipe 4, and the second end 42 of the temperature adjusting water pipe 4 is connected with the second end 12 of the temperature adjusting unit 1.
In this application embodiment, thermoregulation unit, water storage equipment, water supply equipment and thermoregulation water pipe can constitute a circulation circuit, and the thermoregulation unit can be connected with water storage equipment to can adjust the temperature to the coolant liquid in the water storage equipment, and because the thermoregulation water pipe surrounds and treats the cooling member, consequently, when the coolant liquid circulates to the thermoregulation water pipe in, can take away and treat the produced heat of cooling member when the operation, thereby reach the cooling effect to natural gas loop system. In addition, the temperature adjusting unit, the water storage equipment, the water supply equipment and the temperature adjusting water pipe can form a circulation loop, so that the cooling liquid can be repeatedly utilized in the circulation loop, and resources are saved.
It should be noted that the temperature adjusting unit 1, the water storage device 2, the water supply device 3 and the temperature adjusting water pipe 4 may be connected through a water pipe. The temperature adjusting unit 1 can be used for adjusting the temperature of the cooling liquid entering the water storage device 2, and the temperature adjusting device 1 can comprise a heating component and/or a refrigerating component, wherein the heating component is used for increasing the temperature of the cooling liquid entering the water storage device 2, and the refrigerating component is used for reducing the temperature of the cooling liquid entering the water storage device 2. The heating component can be a heater and the like, the refrigerating component can be a condenser, a radiator, a water-cooling unit and the like, the water-cooling unit can be connected with the water storage equipment 2 through a water conveying pipe, and a water inlet, an overflow port and a sewage outlet can be arranged on the water-cooling unit. The temperature adjusting unit 1 can further comprise a water tank, when the temperature of the cooling liquid stored in the water storage device 2 needs to be adjusted, the temperature adjusting unit 1 can suck the cooling liquid in the water storage device 2, then adjust the temperature of the sucked cooling liquid, and then send the cooling liquid with the adjusted temperature to the water storage device 2.
Since the cooling device of the natural gas loop system can cool the component to be cooled under the control of the control device, the control device can be any terminal associated with the natural gas loop system. Therefore, in the embodiment of the present application, the control device may detect the temperature of the member to be cooled 5 during the operation of the member to be cooled 5, and the control device may detect the temperature of the member to be cooled 5 by the temperature sensor installed at the member to be cooled 5. For example, the temperature sensor may detect a temperature generated by the member to be cooled 5 during operation of the member to be cooled 5 and send the detected temperature to the control apparatus. After the control device obtains the temperature detected by the temperature sensor, the temperature is compared with the first temperature threshold, and if the temperature is greater than or equal to the first temperature threshold, the temperature adjusting unit 1 can be controlled to cool the cooling liquid entering the water storage device 2 according to the temperature of the component 5 to be cooled. When the detected temperature is lower than the first temperature threshold value, the control device does not need to control the temperature adjusting unit 1 to adjust the temperature of the cooling liquid entering the water storage device 2.
When the control device controls the temperature adjusting unit 1 to cool the cooling liquid entering the water storage device 2, the control device can determine a corresponding cooling temperature according to the temperature of the component to be cooled; then, the temperature adjusting unit 1 may cool the temperature of the cooling liquid entering the water storage apparatus to a cooling temperature according to the cooling temperature determined by the control apparatus.
In addition, the control apparatus may determine the corresponding cooling temperature according to the temperature of the member to be cooled by: the control device acquires a corresponding cooling temperature from the correspondence between the temperature of the member to be cooled and the cooling temperature, according to the temperature of the member to be cooled. Alternatively, the control apparatus may subtract the second temperature threshold value from the temperature of the member to be cooled to obtain the cooling temperature. The second temperature threshold may be set in advance, for example, the second temperature threshold may be 10 degrees celsius, 15 degrees celsius, or the like.
It should be noted that the control device may detect the temperature of the member to be cooled 5 in real time during the operation of the member to be cooled 5, or may detect the temperature of the member to be cooled 5 at detection time intervals. The detection time interval may be set in advance, for example, the detection time interval may be 5 minutes, 10 minutes, or the like. The first temperature threshold may also be set in advance, and may be different according to the component to be cooled, for example, when the component to be cooled 5 is the heat exchanger 51 in the natural gas loop system, the first temperature threshold may be 30 degrees celsius, 40 degrees celsius, 50 degrees celsius, or the like. When the member to be cooled 5 is the motor 52 of the gas compressor, the first temperature threshold may be 40 degrees celsius, 60 degrees celsius, 80 degrees celsius, 90 degrees celsius, or the like.
Furthermore, the temperature adjusting unit 1 may adjust the temperature of the cooling liquid entering the water storage device 2 according to the cooling temperature determined by the control device, or may directly adjust the temperature of the cooling liquid entering the water storage device 2 to a preset temperature when the temperature of the component to be cooled is greater than or equal to the first temperature threshold, where the preset temperature may be set in advance, for example, the preset temperature may be 10 degrees celsius, 13 degrees celsius, or the like.
The water storage device 2 is used for storing a cooling liquid which can be cooled or heated, and the cooling liquid can be tap water, soft water and the like. When the cooling liquid is soft water, the problems of scaling, scale inhibition and the like of equipment and pipelines can be reduced in the circulating process of the cooling liquid in the circulating loop, the maintenance frequency of the equipment is reduced, and the service life of the equipment is prolonged.
Further, the water storage device 2 may comprise a breathing unit, which may comprise an inhalation structure and an exhalation structure.
The breathing unit is positioned at the top of the water storage device, so that the cavity of the water storage device 2 is a sealed cavity; the air suction structure is used for supplying inert gas to the water storage device, and the air exhaust structure is used for exhausting non-inert gas in the water storage device 2 out of the water storage device 2.
It should be noted that the breathing unit is installed on the top of the cavity of the water storage device 2 to form an intermittently opened and closed sealed cavity. The air suction member may be connected to the top of the chamber of the water storage apparatus 2 and supply the inert gas to the chamber. The exhalation member can also be connected to the top of the cavity of the water storage device 2, and the exhalation member can lead the non-inert gas in the water storage device 2 out of the sealed cavity. The getter member may have an outlet port capable of extending into the cooling liquid in the cavity for delivering an inert gas into the cooling liquid.
It should be noted that the inert gas may be one or more of nitrogen, argon, and the like. The non-inert gas may include oxygen in the chamber, oxygen in the coolant, and other gases that can cause corrosion of the equipment.
It is worth mentioning that the inert gas can be injected into the water storage device 2 and the cooling liquid therein through the inhalation component of the breathing unit, and the inert gas can cover the surface of the cooling liquid and be dissolved in the cooling liquid, so that the non-inert gas dissolved in the cooling liquid is eliminated and further the non-inert gas in the air is prevented from permeating into the cooling liquid, and the non-inert gas in the water storage device 2 and the cooling liquid can be exhausted from the exhalation component, thereby playing a role of corrosion prevention.
Furthermore, as the temperature adjusting unit 1 may further include a heating component, the control device may further control the temperature adjusting unit 1 to heat the cooling liquid entering the water storage device 2, so as to heat a component that needs to be heated in the natural gas loop system.
Referring to fig. 2, the cooling device further comprises a water quantity regulating device 6.
Wherein the first end 61 of the water quantity adjusting device 6 is connected with the second end 32 of the water supply device 3, and the second end 62 of the water quantity adjusting device 6 is connected with the first end 41 of the temperature-adjusting water pipe 4.
It should be noted that the temperature adjusting unit 1, the water storage device 2, the water supply device 3, the water amount adjusting device 6 and the temperature adjusting water pipe 4 may form a circulation loop. The water amount adjusting device 6 may include a valve or a water amount control valve, etc., and the water amount adjusting device 6 may control the amount of the cooling liquid entering the temperature-adjusted water pipe 4 by controlling the opening degree of the valve or the water amount control valve.
Because the temperature adjusting unit 1, the water storage device 2, the water supply device 3, the water quantity adjusting device 6 and the temperature adjusting water pipe 4 can form a circulation loop, the control device can control the cooling liquid cooled in the water storage device to enter the water quantity adjusting device 4 through the water supply device; then, the PID parameter of a proportional-integral-derivative PID controller of the valve in the water quantity regulating device can be adjusted based on the temperature of the component to be cooled and the temperature of the cooled cooling liquid, and the PID parameter is used for changing the opening degree of the valve in the water quantity regulating device; determining the opening degree of a valve in the water quantity adjusting equipment 6 based on the PID parameter; the valve in the water quantity adjusting device 6 can be opened according to a determined opening degree, so that the cooled cooling liquid can enter the temperature adjusting water pipe 4 from the water quantity adjusting device 6.

It should be noted that the cooling liquid in the first water storage tank 23 and the cooling liquid in the second water storage tank 24 may circulate each other, and the first water storage tank 23, the second water storage tank 24 and the water pipe connected therebetween may form a circulation loop, or the first water storage tank 23, the second water storage tank 24, the temperature adjusting unit 1 and the water pipe connected therebetween may form a circulation loop. In the drawings of the embodiments of the present application, it is exemplified that the first water storage tank 23, the second water storage tank 24, the temperature adjusting unit 1 and the water conveying pipe therebetween may constitute a circulation loop.
In addition, the temperature control unit 1 may control the temperature of the coolant in the first water storage tank 23 and the second water storage tank 24, respectively, when controlling the temperature.
It should be noted that, in order to prevent the coolant in the first water storage tank 23 and/or the second water storage tank 24 from moving out of the tank body, when the coolant exists in the first water storage tank 23 and the second water storage tank 24, the liquid level is not higher than the tank body. For example, the height of the first water storage tank 23 is 2.1 meters, the height of the liquid level in the first water storage tank 23 should be no higher than 2.1 meters, the height of the second water storage tank 24 is 2 meters, and the height of the liquid level in the second water storage tank 24 should be no higher than 2 meters.
Moreover, the first water storage tank 23 and the second water storage tank 24 can be provided with a sewage draining outlet and an overflow outlet, and the overflow outlet is close to the air outlet of the air suction component and is lower than the air outlet of the air suction component.
It should be noted that, since the water storage apparatus 2 includes the first water storage tank 23 and the second water storage tank 24, the temperature adjustment unit 1 can deliver the cooling liquid in the second water storage tank 24 to the first water storage tank 23, and also can deliver the cooling liquid in the first water storage tank 23 to the second water storage tank 24, so as to ensure that the amounts of the cooling liquids in the two water storage tanks are in dynamic balance. For example, after the temperature adjustment unit cools the coolant in the second water storage tank 24, the coolant in the second water storage tank 24 may be transferred to the first water storage tank 23.
Referring to fig. 4, the water supply apparatus 3 includes a first water supply unit 33 and a second water supply unit 34, the temperature-adjusted water pipe 4 includes a first water pipe 43 and a second water pipe 44, and the member to be cooled 5 includes a heat exchanger 51 and a motor 52 of a gas compressor in a natural gas loop system.

Because the first water pipe 43 surrounds the motor 52 and the second water pipe 44 surrounds the heat exchanger 51, when the cooling liquid in the water storage device 2 circulates to the first water pipe 43 and the second water pipe 44, the cooling liquid can take away the heat generated by the motor 52 and the heat exchanger 51 respectively, so as to achieve the purpose of cooling the natural gas loop system.
In addition, since the water storage apparatus 2 includes the first water storage tank 23 and the second water storage tank 24, referring to fig. 5, the first end 331 of the first water supply unit 33 and the first end 341 of the second water supply unit 34 are connected to the second end 232 of the first water storage apparatus 23, respectively.

In addition, the temperature adjusting unit, the water storage equipment, the water supply equipment and the temperature adjusting water pipe can form a circulation loop, so that the cooling liquid can be repeatedly utilized in the circulation loop, and resources are saved.
Fig. 9 is a flowchart of a cooling method of a natural gas loop system according to an embodiment of the present application, and referring to fig. 9, the method is applied to a control device for controlling a cooling apparatus of the natural gas loop system shown in any one of fig. 1 to 8, and the steps include the following steps.
Step 901: the control device detects the temperature of the member to be cooled during operation of the member to be cooled.
Since the temperature around the thermometer of the component to be cooled will rise during the operation of the component to be cooled, and the normal operation of the component to be cooled will be affected when the temperature is too high, in order to ensure that the component to be cooled can operate normally, the control device may detect the temperature of the component to be cooled during the operation of the component to be cooled.
Wherein the control device may detect the temperature of the member to be cooled through a temperature sensor installed at the member to be cooled. For example, the temperature sensor may detect a temperature generated by the member to be cooled during operation of the member to be cooled, and send the detected temperature to the control apparatus.
It should be noted that the control device may detect the temperature of the member to be cooled in real time during the operation of the member to be cooled, or may detect the temperature of the member to be cooled 5 at detection time intervals. The detection time interval may be set in advance, for example, the detection time interval may be 5 minutes, 10 minutes, or the like.
Step 902: when the temperature of the member to be cooled is greater than or equal to the first temperature threshold value, the control device controls the temperature adjusting unit to cool the cooling liquid entering the water storage device according to the temperature of the member to be cooled.
Since when the temperature of the member to be cooled is greater than or equal to the first temperature threshold, it indicates that the normal operation of the member to be cooled is likely to be affected by the excessively high temperature of the member to be cooled, in order to ensure that the member to be cooled can be cooled, the control device may control the temperature adjustment unit to cool the coolant entering the water storage device according to the temperature of the member to be cooled, and the operation of controlling the temperature adjustment unit to cool the coolant entering the water storage device according to the temperature of the member to be cooled may be: determining a corresponding cooling temperature according to the temperature of the component to be cooled; and controlling the temperature adjusting unit to cool the temperature of the cooling liquid entering the water storage equipment to a cooling temperature.
Wherein, the operation of the control device determining the corresponding cooling temperature according to the temperature of the member to be cooled may be: according to the temperature of the component to be cooled, the corresponding cooling temperature is obtained from the corresponding relation between the temperature of the component to be cooled and the cooling temperature. Or subtracting the second temperature threshold value from the temperature of the component to be cooled to obtain the cooling temperature.
It should be noted that the first temperature threshold may be set in advance, and the first temperature threshold is different according to the component to be cooled, for example, when the component to be cooled is a heat exchanger in a natural gas loop system, the first temperature threshold may be 30 degrees celsius, 40 degrees celsius, 50 degrees celsius, or the like. When the member to be cooled is a motor of a gas compressor, the first temperature threshold may be 40 degrees celsius, 60 degrees celsius, 80 degrees celsius, 90 degrees celsius, or the like. The second temperature threshold may also be set in advance, for example, the second temperature threshold may be 10 degrees celsius, 15 degrees celsius, or the like.
In addition, the control device may control the temperature adjustment unit to adjust the temperature of the cooling liquid entering the water storage device according to the determined cooling temperature, or may control the temperature adjustment unit to adjust the temperature of the cooling liquid entering the water storage device to a preset temperature directly when the temperature of the member to be cooled is greater than or equal to the first temperature threshold, where the preset temperature may be set in advance, for example, the preset temperature may be 10 degrees celsius, 13 degrees celsius, or the like.
Furthermore, when the detected temperature is less than the first temperature threshold, the control device does not need to control the temperature adjusting unit to adjust the temperature of the cooling liquid entering the water storage device.
The coolant may be tap water, soft water, or the like. When the cooling liquid is soft water, the problems of scaling, scale inhibition and the like of equipment and pipelines can be reduced in the circulating process of the cooling liquid in the circulating loop, the maintenance frequency of the equipment is reduced, and the service life of the equipment is prolonged.
Step 903: the control device controls the cooled cooling liquid in the water storage device to enter the temperature adjusting water pipe through the water supply device, and when the cooled cooling liquid passes through the temperature adjusting water pipe, the cooling component to be cooled surrounded by the temperature adjusting water pipe is cooled.
Therefore, the water supply device can be connected with the temperature-adjusting water pipe, and the temperature-adjusting water pipe can surround the component to be cooled, so that the control device can control the water supply device to enable the cooled cooling liquid in the water storage device to enter the temperature-adjusting water pipe.
In addition, as can be seen from the above, the cooling apparatus further includes water amount adjusting means; therefore, when the water quantity adjusting device is included, the operation of the control device for controlling the cooling liquid cooled in the water storage device to enter the temperature adjusting water pipe through the water supply device can be as follows: the water supply equipment controls the cooled cooling liquid in the water storage equipment to enter the water quantity adjusting equipment; adjusting a PID parameter of a valve proportion-integral-derivative PID controller in the water quantity adjusting device based on the temperature of the component to be cooled and the temperature of the cooled cooling liquid, wherein the PID parameter is used for changing the opening degree of a valve in the water quantity adjusting device; determining the opening degree of a valve in the water quantity adjusting equipment based on the PID parameter; and controlling a valve in the water quantity regulating equipment to be opened according to the determined opening degree so as to enable the cooled cooling liquid to enter the temperature regulating water pipe from the water quantity regulating equipment.
In the embodiment of the application, the control device can detect the temperature of the member to be cooled in the operation process of the member to be cooled, and control the temperature adjusting unit to cool the cooling liquid entering the water storage device according to the temperature of the member to be cooled when the temperature of the member to be cooled is greater than or equal to the first temperature threshold value. The temperature adjusting unit, the water storage equipment, the water supply equipment and the temperature adjusting water pipe can form a circulation loop, and the temperature adjusting water pipe surrounds the component to be cooled, so that the control equipment can control the cooling liquid cooled in the water storage equipment to enter the temperature adjusting water pipe through the water supply equipment, and when the cooling liquid circulates into the temperature adjusting water pipe, the heat generated when the component to be cooled runs can be taken away, so that the cooling effect on the natural gas loop system is achieved. In addition, the temperature adjusting unit, the water storage equipment, the water supply equipment and the temperature adjusting water pipe can form a circulation loop, so that the cooling liquid can be repeatedly utilized in the circulation loop, and resources are saved.
