Description

Technical Field

[0001] The present invention relates to the technical field of waste heat and waste energy utilization and energy and water saving in coal chemical industry, and in particular to a cooling system for a coal gas generator set and a coal gas generator set. Background Art

[0002] In the process of development and utilization of coal resources, environmental protection and sustainable development are issues that cannot be ignored. The state encourages the coal industry to develop in the direction of high-end, intelligent, and green, and promotes the deep integration of coal with new energy, chemical and other industries. A large amount of coal gas will be produced in the process of deepening the utilization of coal. After the coal gas is produced, it needs to be purified to remove impurities, such as dust, sulfides, etc., to meet the use requirements of different fields. The purified coal gas can be used as an efficient fuel for power generation, industrial heating, urban gas and other fields. The gas generator set has reliable operation, strong adaptability, and fast return on investment. It is a very energy-saving and environmentally friendly coal utilization solution with broad application prospects in the northwest region.

[0003] Due to the scarcity of water resources in the northwest region, water conservation is very important. Therefore, in the construction of gas-fired generator sets in the northwest region, it is necessary to fully consider the local environmental characteristics and challenges, and then adopt reliable solutions to deal with water conservation issues. Therefore, water-saving equipment and processes need to be used during the design and construction process to reduce the waste of water resources.

[0004] During the operation of a power plant, various auxiliary equipment will generate a large amount of heat, which needs to be dissipated through a cooling system to ensure the normal operation of the equipment and the power generation efficiency. Among them, the heat generated by the condensation of the exhaust steam of the steam turbine is the largest heat-generating part of the gas-fired generator set. In water-scarce areas, this part of the heat is directly cooled by the air cooling system, while the heat dissipation of the auxiliary equipment supporting the gas-fired generator set requires another system for cooling. Conventional gas-fired generator sets use cooling water to cool the auxiliary equipment. In water-cooled units, the cooling water cannot be effectively recovered, resulting in evaporation loss, wind loss and sewage loss, which in turn causes a huge waste of water resources.

[0043] In the process of development and utilization of coal resources, environmental protection and sustainable development are issues that cannot be ignored. The state encourages the coal industry to develop in the direction of high-end, intelligent, and green, and promotes the deep integration of coal with new energy, chemical and other industries. A large amount of coal gas will be produced in the process of deepening the utilization of coal. After the coal gas is produced, it needs to be purified to remove impurities, such as dust, sulfides, etc., to meet the use requirements of different fields. The purified coal gas can be used as an efficient fuel for power generation, industrial heating, urban gas and other fields. The gas generator set has reliable operation, strong adaptability, and fast return on investment. It is a very energy-saving and environmentally friendly coal utilization solution with broad application prospects in the northwest region.

[0044] Due to the scarcity of water resources in the northwest region, water conservation is very important. Therefore, in the construction of gas-fired generator sets in the northwest region, it is necessary to fully consider the local environmental characteristics and challenges, and then adopt reliable solutions to deal with water conservation issues. Therefore, water-saving equipment and processes need to be used during the design and construction process to reduce the waste of water resources.

[0045] During the operation of a power plant, various auxiliary equipment will generate a large amount of heat, which needs to be dissipated through the cooling system to ensure the normal operation of the equipment and the power generation efficiency. Among them, the heat generated by the condensation of the exhaust steam of the steam turbine is the largest heat-generating part in the gas-fired generator set. This part of the heat is directly cooled by the air cooling system, while the heat dissipation of the auxiliary equipment supporting the gas-fired generator set requires another system for cooling. Conventional gas-fired generator sets use cooling water to cool the auxiliary equipment. In water-cooled units, the cooling water cannot be effectively recovered, resulting in evaporation loss, wind loss and sewage loss, which in turn causes a huge waste of water resources.

[0046] In order to solve the above problems, the present invention proposes a gas generator set cooling system and a gas generator set, aiming to provide a gas generator set cooling system and a gas generator set which can both cool and save water. Figure 1 to Figure 2 A schematic structural diagram of an embodiment of a cooling system for a coal gas generator set of the present invention.

[0047] Please refer to Figure 1 In one embodiment of the present invention, the gas generator set cooling system 100 is applied to the gas generator set, including a tower body 1, a circulation pipeline 2 and a circulation pump body 3. The tower body 1 contains a first cooling medium in a closed arrangement; the circulation pipeline 2 is connected to the tower body 1 in a closed circulation manner; the circulation pump body 3 is installed in the circulation pipeline 2 to drive the first cooling medium to reciprocate from the tower body 1 along the circulation pipeline 2; wherein the first cooling medium is used to absorb the heat generated by the auxiliary device 200 on the gas generator set, and the tower body 1 is used to perform heat exchange cooling on the first cooling medium.

[0048] The technical solution of the present invention adopts connecting the auxiliary device 200 to the circulation pipeline 2, and the first cooling medium reciprocating in the circulation pipeline 2 absorbs the heat generated by the auxiliary device 200, and then the tower body 1 cools the first cooling medium in a closed arrangement. Such an arrangement can not only cool the auxiliary device 200, but also protect the first cooling medium from loss, thereby achieving a saving effect.

[0049] It is understandable that in the northwest region, wind resources are very abundant and the wind direction is relatively stable, and the wind energy density is high. When planning the gas generator system, the use of wind power should also be considered simultaneously. In this example, by utilizing the abundant wind resources in the northwest region, the first cooling medium in the closed arrangement in the tower body 1 is cooled and cooled, and then the first cooling medium is used to cool the auxiliary equipment of the gas generator set, thereby forming a system that saves water and effectively utilizes wind energy, which is of great value in the construction of the gas generator set in the northwest region and has a significant water-saving effect.

[0050] For further information, please refer to Figure 1 and Figure 2 The circulation pipeline 2 includes a liquid outlet pipe 21 and a liquid inlet pipe 22, which are respectively installed at the liquid outlet port 11 and the liquid inlet port 12 of the tower body 1; the tower body 1 also includes a heat exchange coil 13, with two ends respectively connected to the liquid outlet pipe 21 and the liquid inlet pipe 22, so as to cool the first cooling medium; wherein the first cooling medium circulates in the liquid outlet pipe 21, the liquid inlet pipe 22 and the heat exchange coil 13.

[0051] It can be understood that the heat exchange coil 13 is arranged in a spiral rotation, so that the surface area of ​​the heat exchange coil 13 is increased, and heat can be fully exchanged between the first cooling medium and the air, thereby achieving a cooling effect. In order to achieve the cooling effect of the first cooling medium on the auxiliary device 200 of the gas generator set, specifically, the circulation pipeline 2 includes the liquid outlet pipe 21 and the liquid inlet pipe 22, which are respectively installed on the liquid outlet port 11 and the liquid inlet port 12 of the tower body 1, and the two ends of the heat exchange coil 13 are respectively connected to the liquid outlet pipe 21 and the liquid inlet pipe 22, and the first cooling medium circulates in the liquid outlet pipe 21, the liquid inlet pipe 22 and the heat exchange coil 13. At the same time, the auxiliary device 200 of the gas generator set is connected between the liquid outlet pipe 21 and the liquid inlet pipe 22, and the first cooling medium is driven by the circulation pump body 3 to circulate back and forth along the circulation pipeline 2, thereby achieving the cooling effect of the first cooling medium on the auxiliary device 200 of the gas generator set.

[0052] Specifically, the auxiliary device 200 of the gas generator set includes an oil cooler 201, an air cooler 202 and auxiliary equipment 203. In order to achieve higher cooling efficiency, the oil cooler 201, the air cooler 202 and the auxiliary equipment 203 are connected in parallel in the circulation pipeline 2.

[0053] For further information, please refer to Figure 1 and Figure 2 , the tower body 1 also includes cooling blades 14 and a motor 15. The cooling blades 14 are installed at the top of the tower body 1 and are arranged opposite to the heat exchange coil 13; the motor 15 is electrically connected to the cooling blades 14 to drive the cooling blades 14 to rotate. It can be understood that although the wind resources in the northwest region are very rich, the wind force level varies with the weather and seasons. In order to further provide more stable cooling air for the first cooling medium and thus accelerate the cooling rate of the first cooling medium, the tower body 1 also includes the cooling blades 14 and the motor 15. The cooling blades 14 are installed at the top of the tower body 1 and are arranged opposite to the heat exchange coil 13; the motor 15 is electrically connected to the cooling blades 14 to drive the cooling blades 14 to rotate.

[0054] It is understandable that, as is well known, cold air has a greater density than hot air and has a greater tendency to settle downward. Therefore, the cooling blades 14 are arranged at the top of the tower body 1, facing the heat exchange coil 13, which is more conducive to driving the cold air to settle to the surrounding side of the heat exchange coil 13 as driven by the cooling blades 14, thereby cooling the first cooling medium enclosed in the heat exchange coil 13, thereby further improving the cooling efficiency of the first cooling medium in the heat exchange coil 13, and can better cool the auxiliary device 200 of the gas generator set.

[0055] It is understandable that, leaving aside environmental factors, when the power of the gas generator set rises to a relatively large level, the heat generated by the gas generator set also greatly increases. At this time, in order to ensure the normal operation of the gas generator set, it is necessary to cool down the auxiliary device 200 more quickly. Therefore, the rate at which the first cooling medium absorbs heat is also increasing. At this time, the cooling efficiency of the first cooling medium is required to be improved. Therefore, the motor 15 is required to drive the cooling blades 14 to cool down the first cooling medium that absorbs a large amount of heat in the heat exchange coil 13 more quickly, thereby ensuring the normal operation of the gas generator set.

[0056] In addition, please refer to Figure 1, the gas generator set cooling system 100 also includes an auxiliary cooling system 4 for cooling the first cooling medium in the liquid outlet pipe 21. It is understandable that under some extreme conditions, such as when the gas generator set is running at high load or the ambient temperature is high, the cooling effect of the cooling blades 14 on the first cooling medium in the heat exchange coil 13 is not ideal, which in turn causes the first cooling medium to have an unsatisfactory cooling effect on the auxiliary device 200 of the gas generator set, thereby causing the gas generator set to fail to operate normally. Therefore, in some embodiments, the gas generator set cooling system 100 also includes the auxiliary cooling system 4 for directly cooling the first cooling medium in the liquid outlet pipe 21, thereby improving the cooling effect of the first cooling medium on the auxiliary device 200.

[0057] For further information, please refer to Figure 1 The auxiliary cooling system 4 includes a liquid storage tank 41, a liquid spraying pipeline 42 and a liquid spraying pump body 43; the liquid storage tank 41 is used to accommodate the second cooling medium; one end of the liquid spraying pipeline 42 is connected to the liquid storage tank 41, and the other end is opposite to the liquid outlet pipe 21; the liquid spraying pump body 43 is installed in the liquid spraying pipeline 42, and is used to drive the second cooling medium to move from the liquid storage tank 41 along the liquid spraying pipeline 42 to the liquid outlet pipe 21.

[0058] It can be understood that in order to achieve further cooling of the first cooling medium under some extreme conditions, such as when the gas generator set is running at high load or the ambient temperature is high, so as to ensure the normal operation of the gas generator set, the auxiliary cooling system 4 includes the liquid storage tank 41, the liquid spraying pipeline 42 and the liquid spraying pump body 43. The liquid storage tank 41 is used to accommodate the second cooling medium. One end of the liquid spraying pipeline 42 is connected to the liquid storage tank 41, and the other end is opposite to the liquid outlet pipe 21. The liquid spraying pump body 43 is installed in the liquid spraying pipeline 42, and then drives the second cooling medium to move from the liquid storage tank 41 along the liquid spraying pipeline 42 to the liquid outlet pipe 21. With such an arrangement, when necessary, the second cooling medium is driven by the liquid spraying pump body 43 to move from the liquid storage tank 41 along the liquid spraying pipeline 42 to the liquid outlet pipe 21, and then sprayed on the liquid outlet pipe 21, so as to achieve the technical effect of further cooling the first cooling medium.

[0059] For further information, please refer to Figure 1, the liquid reservoir 41 is arranged below the liquid outlet pipe 21. It is understandable that due to the scarcity of water resources in the northwest region, water conservation is a very important issue. Therefore, in this embodiment, the liquid reservoir 41 is arranged below the liquid outlet pipe 21, so that the second cooling medium sprayed on the liquid outlet pipe 21 can be recovered into the liquid reservoir 41, and then the liquid spray pump body 43 drives this part of the recovered second cooling medium to continue to spray from the liquid reservoir 41 along the liquid spray circuit to the liquid outlet pipe 21, thereby realizing recycling and saving the second cooling medium; it is understandable that since the liquid reservoir 41 is open, the heat absorbed by the second cooling medium will be naturally released into the air.

[0060] Furthermore, the liquid reservoir 41 also includes a pressure sensor, which is arranged at the bottom of the liquid reservoir 41, for detecting the pressure value of the second cooling medium; wherein, when the measured pressure value is less than a preset pressure, the second cooling medium starts to be replenished into the liquid reservoir 41; when the measured pressure value is greater than the preset pressure, the second cooling medium stops being replenished into the liquid reservoir 41.

[0061] Understandably, please refer to Figure 1 Since the liquid storage tank 41 is open, the heat absorbed by the second cooling medium will be naturally released into the air, which causes evaporation loss and wind loss of the second cooling medium. Therefore, as time goes by and the second cooling medium in the liquid storage tank 41 is sprayed and cooled on the liquid outlet pipe 21 for many times, the amount of the second cooling medium in the liquid storage tank 41 becomes increasingly insufficient, thereby affecting the cooling effect of the first cooling medium at the liquid outlet pipe 21. Therefore, it is necessary to replenish the second cooling medium in the liquid storage tank 41 in time.

[0062] Specifically, in the present embodiment, the liquid reservoir 41 further comprises the pressure sensor, which is arranged at the bottom of the liquid reservoir 41 to detect the pressure value of the second cooling medium; it is understandable that, as is well known, the pressure of the liquid is related to the depth, and when the second cooling medium decreases, that is, the depth of the second cooling medium in the liquid reservoir 41 is becoming shallower, and then the pressure value is becoming smaller, thus, by setting the pressure sensor, when the measured pressure value is less than the preset pressure, it means that the amount of the second cooling medium in the liquid reservoir 41 is insufficient, and then the second cooling medium is started to be supplemented into the liquid reservoir 41; when the measured pressure value is greater than the preset pressure, it means that the amount of the second cooling medium in the liquid reservoir 41 is sufficient, and then the supplement of the second cooling medium into the liquid reservoir 41 is stopped.

[0063] Furthermore, the first cooling medium includes desalted water; and / or the second cooling medium includes industrial water. It is understandable that the medium used for cooling needs to have properties such as large specific heat capacity and fast heat absorption, so water is a good choice. However, general water is corrosive, and circulating in the circulation pipeline will gradually corrode the equipment, causing damage and affecting the cooling effect of the gas generator set. Therefore, the first cooling medium uses the desalted water, which is desalted, thereby greatly reducing its corrosiveness, and at the same time, the specific heat capacity is large enough, and the cooling effect is good.

[0064] It can be understood that since the second cooling medium of the liquid storage tank 41 cools the first cooling medium at the liquid outlet pipe 21, if it only plays a cooling role, the requirements for water quality do not need to be so high. In addition, since water resources in the northwest region are very scarce, in this embodiment, roughly treated industrial water can be used for cooling, thereby greatly saving the use of water resources.

[0065] In addition, the tower body 1 also includes a temperature sensor, which is arranged at the liquid outlet port 11 to detect the temperature value of the first cooling medium in the liquid outlet pipe 21; when the measured temperature value is greater than the preset temperature, the auxiliary cooling system 4 is started; when the measured temperature value is less than the preset temperature, the auxiliary cooling system 4 is turned off.

[0066] It can be understood that in order to further save water resources, the auxiliary cooling system 4 is only turned on at special times, such as when the weather temperature is high or the gas generator set is running at high load. As for when to turn on the auxiliary cooling system 4, in this embodiment, the tower body 1 also includes the temperature sensor, which is arranged at the liquid outlet port 11 to detect the temperature value of the first cooling medium in the liquid outlet pipe 21. The temperature of the first cooling medium in the liquid outlet pipe 21 is a reference value. If the temperature of the first cooling medium in the liquid outlet pipe 21 is too high, it will inevitably affect the absorption of heat by the auxiliary device 200. Therefore, when the measured temperature value is greater than the preset temperature, it means that the temperature of the first cooling medium is still high after being cooled by the cooling blades 14 of the tower body 1, and further cooling is required, and then the auxiliary cooling system 4 is started; when the measured temperature value is less than the preset temperature, it means that the temperature of the first cooling medium is low enough after being cooled by the cooling blades 14 of the tower body 1, and further cooling is not required, and then the auxiliary cooling system 4 is turned off.

[0067] The present invention further proposes a gas generator set, which includes a gas generator set cooling system 100. The specific structure of the gas generator set cooling system 100 refers to the above embodiment. Since the gas generator set adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0068] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
