Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The offshore flexible and straight platform cooling control method of the present invention is described below with reference to fig. 1-2.
As shown in fig. 1, the present embodiment proposes a first offshore flexible and straight platform cooling control method, which may include the steps of:
S101, responding to equipment cooling instructions, starting N seawater pumps so that the N seawater pumps can extract seawater from a sea area and drive the seawater to be discharged to the sea area through a seawater collecting main pipe and M heat exchangers, and carrying out heat exchange on M equipment corresponding to the M heat exchangers one by one; wherein N and M are positive integers greater than 1.
It should be noted that the present embodiment may be applied to a marine flexible and straight platform cooling control system.
The equipment cooling instruction can be manually input to the offshore flexible and straight platform cooling control system by a technician, can be generated and input to the offshore flexible and straight platform cooling control system when the temperature of the related equipment is monitored to reach a certain threshold value by the related monitoring system, and can be generated and input to the offshore flexible and straight platform cooling control system when the offshore flexible and straight platform is operated.
Alternatively, the M heat exchangers may be connected in series or in parallel. Of course, the M heat exchangers may also be connected in series-parallel.
Specifically, when M heat exchangers are connected in parallel, the output end of the seawater gathering main pipe can be connected with the public input end of the M heat exchangers, and the public output end of the M heat exchangers can be connected with the sea area.
Specifically, the seawater extracted by the N seawater pumps may be collected into a seawater collecting main pipe. When the M heat exchangers are connected in parallel, the seawater collecting main pipe can respectively convey seawater to the M heat exchangers for heat exchange, and the M corresponding devices are cooled. The seawater output by the M heat exchangers can be discharged into the sea area.
It should be noted that, in this embodiment, when the M heat exchangers are connected in parallel, if a pipeline where a certain heat exchanger is located fails or needs to be maintained, only a valve arranged on the pipeline needs to be closed and the pipeline needs to be maintained, and pipelines where other heat exchangers are located can still work normally, so as to ensure the stability and reliability of equipment cooling. In addition, the heat load of different devices can be uniformly distributed on different pipelines, so that the different devices share cooling resources, the uniform distribution of the cooling load is realized, poor cooling effect or overload of certain devices is avoided, and the cooling stability and reliability of the devices are improved.
S102, monitoring the heat dissipation capacity of each device; the heat dissipation capacity of the equipment is the heat transferred to the seawater by the equipment through the corresponding heat exchanger.
Specifically, the present embodiment can continuously monitor the heat dissipation capacity of each device.
Optionally, the step S102 may include:
for any device, the temperature of the incoming seawater, the temperature of the outgoing seawater and the seawater flow of the corresponding heat exchanger are monitored, and the heat dissipation capacity of the device is determined according to the temperature of the incoming seawater, the temperature of the outgoing seawater and the seawater flow.
Specifically, the embodiment can determine the sea water temperature difference according to the sea water inlet temperature and the sea water outlet temperature, and can determine the heat dissipation capacity of the device according to the sea water temperature difference and the sea water flow.
Specifically, the present embodiment may determine the heat dissipation capacity of the device according to the calculation formula of the heat dissipation capacity Q. The formula is q= (q×c×Δt)/3.6.
Wherein q is the seawater flow. C is the specific heat capacity of water, 4.18 kJ/(kg. Deg.C). Δt is the sea water temperature difference.
As shown in fig. 2, the N may be 4, and the M devices are a converter valve, a coupling transformer, and an air conditioner, respectively, and in this embodiment, the M heat exchangers are connected in parallel and the connection relationship between the related devices is shown. 11. 12, 13 and 14 respectively denote a seawater pump, 21, 22, 23 and 24 respectively denote check valves, 15 denotes a filter, 31, 32 and 33 respectively denote an intake water temperature monitor, a seawater flow rate monitor and an outlet water temperature monitor of the converter valve heat exchanger 16, 34, 35 and 36 respectively denote an intake water temperature monitor, a seawater flow rate monitor and an outlet water temperature monitor of the coupling variable heat exchanger 17, and 37, 38 and 39 respectively denote an intake water temperature monitor, a seawater flow rate monitor and an outlet water temperature monitor of the air conditioner heat exchanger 18. 41 denotes the temperature of the sea water discharged to the sea area. MO denotes a pump, and TT and FT denote a temperature monitor and a flow rate detector, respectively.
It should be noted that, the intake water pipeline of each heat exchanger may be sequentially connected to the cooling water supply system and the cooling water return system of the corresponding device, for example, the intake water pipeline of the converter valve heat exchanger may be sequentially connected to the cooling water supply system and the cooling water return system of the converter valve, the intake water pipeline of the connection heat exchanger may be sequentially connected to the cooling water supply system and the cooling water return system of the connection change, and the intake water pipeline of the air conditioner heat exchanger may be sequentially connected to the cooling water supply system and the cooling water return system of the air conditioner, and then discharged to the sea through the discharge main pipe.
S103, controlling the start-stop state of at least one seawater pump according to the heat dissipation capacity of at least one device.
Specifically, the embodiment can control the start-stop state of the seawater pump, namely, control the running state or the shutdown of the seawater pump according to the monitored heat dissipation capacity of at least one device, so as to control the running quantity of the seawater pump and the cooling intensity of the device.
Optionally, N is 3, and the m devices include a converter valve, a coupling transformer, and an air conditioner.
Optionally, the step S103 may include:
For any device, monitoring the difference value between the rated heat dissipation capacity and the heat dissipation capacity of the device, and determining a first set threshold corresponding to the device, wherein the first set threshold is the product of the rated heat dissipation capacity and a first preset coefficient of the device; wherein the first preset coefficient is greater than 0 and less than 1;
and under the condition that the difference value corresponding to each device is larger than the corresponding first set threshold value, stopping the first seawater pump, wherein the first seawater pump is one of N seawater pumps.
It should be noted that, the heat dissipation capacity of the device monitored in this embodiment is the actual heat dissipation capacity of the device. The rated heat dissipation capacity of the device can be set by the skilled person according to the actual situation.
The first set threshold is obtained by multiplying rated heat dissipation capacity of the equipment by a first preset coefficient. The first preset coefficient may be set by a technician according to actual situations, for example, the first preset coefficient may be set to 0.6.
Specifically, the embodiment may subtract the actual heat dissipation capacity from the rated heat dissipation capacity of the device to obtain a corresponding difference value.
Specifically, when three conditions are met, the embodiment can stop one seawater pump and keep the working conditions of the two seawater pumps running. The three conditions are that the difference value (Q12-Q11) between the rated heat dissipating capacity Q12 and the actual heat dissipating capacity Q11 of the converter valve is larger than a set value 0.6Q12, the difference value (Q22-Q21) between the variable rated heat dissipating capacity Q22 and the actual heat dissipating capacity Q21 is larger than a set value 0.6Q22, and the difference value (Q32-Q31) between the rated heat dissipating capacity Q32 and the actual heat dissipating capacity Q31 of the air conditioning system is larger than a set value 0.6Q32.
It will be appreciated that the heat dissipation capacity of the device is closely related to the load on the device. When the heat dissipation capacity of the device is large, the device load is high. When the heat dissipation capacity of the device is low, it means that the device load is low. When the heat dissipation capacity of the device changes, the device load is indicated to change. According to the embodiment, the running number of the seawater pumps and the cooling intensity of the equipment are controlled according to the heat dissipation capacity of the equipment, namely the cooling intensity of the equipment can be controlled according to the load control of the equipment, and the cooling intensity of the equipment can be controlled in quick response to the load change of the equipment.
It should be noted that if the cooling intensity of the equipment cannot be controlled in response to the change of the load of the equipment, hysteresis may exist in the cooling control, for example, the related technology starts and stops the sea water pump according to the sea water temperature, the change of the load of the equipment cannot be adapted, the hysteresis exists in the cooling control, the related equipment may generate dew, and high-pressure equipment such as a converter valve breaks down when serious, so that safety risks exist.
The cooling control performed by the embodiment can realize the control of the cooling intensity of the equipment in quick response to the change of the equipment load, effectively eliminate the hysteresis of the cooling control, effectively adapt to the change of the equipment load, avoid the generation of condensation water by related equipment, reduce the risk of breakdown of high-pressure equipment such as a converter valve due to the condensation water, and further improve the safety of the equipment.
According to the offshore flexible straight platform cooling control method, the starting and stopping state of the seawater pump can be controlled according to the monitored heat dissipation capacity of at least one device, namely the seawater pump is controlled to keep in an operating state or stop running, so that the operation quantity of the seawater pump and the cooling intensity of the device are controlled.
Based on fig. 1, the present embodiment proposes a second offshore flexible and straight platform cooling control method, which may further include, after performing the step of stopping the first seawater pump, the steps of:
determining a second set threshold corresponding to each device, wherein the second set threshold is the product of the rated heat dissipation capacity of the device and a second preset coefficient; wherein the second preset coefficient is greater than 0 and smaller than the first preset coefficient;
and under the condition that the difference value corresponding to any one device is smaller than the corresponding second set threshold value, starting the first seawater pump.
The second preset coefficient may be set by a technician according to actual situations, which is not limited in this embodiment. For example, when the first preset coefficient is 0.6, the second preset coefficient may be 0.4.
Specifically, the embodiment may continuously monitor the actual heat dissipating capacity of each device after the first seawater pump is stopped, and calculate the difference between the rated heat dissipating capacity and the actual heat dissipating capacity of each device. And when any one of the three preset conditions meets the requirement, starting the first seawater pump again. The three conditions may include that the difference value (Q12-Q11) between the rated heat dissipating capacity and the actual heat dissipating capacity of the converter valve is smaller than a set value 0.4Q12, the difference value (Q22-Q21) between the rated heat dissipating capacity and the actual heat dissipating capacity of the connection transformer is smaller than a set value 0.4Q22, and the difference value (Q32-Q31) between the rated heat dissipating capacity and the actual heat dissipating capacity of the air conditioner is smaller than a set value 0.4Q32. It can be understood that the second preset coefficient is 0.4 at this time.
According to the offshore flexible straight platform cooling control method, the starting and stopping state of the seawater pump can be controlled according to the monitored heat dissipation capacity of at least one device, namely the seawater pump is controlled to keep in an operating state or stop operation, so that the operation quantity of the seawater pump and the cooling intensity of the device are controlled, the control of the cooling intensity of the device is effectively realized, and the safety of the device is improved.
Based on fig. 1, the present embodiment proposes a third offshore flexible and straight platform cooling control method, which may further include, after the step S101, the steps of:
Monitoring the temperature difference between the sea water inlet temperature and the sea water outlet temperature of each heat exchanger;
And under the condition that the temperature difference corresponding to each heat exchanger is determined to be larger than a preset threshold value, starting the standby seawater pump so that the standby seawater pump can extract seawater from the sea area and drive the seawater to be discharged to the sea area through the seawater collecting main pipe and the M heat exchangers.
The preset threshold may be set by a technician according to actual situations, which is not limited in this embodiment. For example, it may be set at 10 degrees celsius.
As shown in fig. 2, three seawater pumps denoted by 11, 12 and 13 may be used as a common seawater pump, and a seawater pump denoted by 14 may be used as a standby seawater pump. In this embodiment, when a device cooling command is received, three common seawater pumps may be started. When the temperature differences are all larger than the preset threshold, the equipment load is determined to reach the maximum intensity, and the standby water pump can be started in the embodiment, so that the cooling intensity of the equipment is further enhanced, and the safety of the equipment is guaranteed.
According to the offshore flexible and straight platform cooling control method, the standby water pump can be arranged, the standby water pump is not required to be started when not needed, the energy consumption is reduced, the standby water pump can be started when necessary, the cooling strength of equipment is further enhanced, and the safety of the equipment is guaranteed.
