Description
Technical Field
The application relates to the technical field of gas chamber operation control, in particular to a gas chamber operation control method, a monitoring system and electronic equipment.
Background
The gas holder is a device which can be used for stabilizing the pressure of a gas pipe network. The piston is arranged in the gas chamber, and the gas chamber can send and receive gas of a gas pipe network through the up-and-down movement of the piston, so that the pressure of the gas pipe network can be adjusted.
For the on-line grid-connected operation mode adopted by the existing gas cabinet, the gas cabinet is communicated with a gas pipe network, namely, a piston of the gas cabinet moves up and down according to the pressure change of the gas pipe network under the condition that a communication valve between the gas cabinet and the gas pipe network is fully opened. When the pressure of the gas pipe network is higher than that of the gas tank, the piston moves upwards, and the gas tank sucks gas from the gas pipe network, so that the tank capacity of the gas tank rises. When the pressure of the gas pipe network is lower than that of the gas tank, the piston moves downwards, the gas tank supplies gas to the gas pipe network, the tank capacity of the gas tank is reduced, and therefore the pressure regulating function of the gas tank is achieved.

Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
The gas tank is a large-scale device, and the internal capacity of the gas tank can reach thousands of cubic meters to dozens of thousands of cubic meters according to different requirements. In the operation process of the gas chamber, the gas chamber may have operation risks such as deformation of the chamber body, inclination of the piston, clamping stagnation of the piston and the like.
The gas pipe network connected with the gas cabinet comprises at least one gas pipeline. The gas pipelines are connected with large-scale equipment such as a large blast furnace, a large coke oven and a large generator set of a steel mill, and when the large-scale equipment such as a blast furnace gas production device, a coke oven gas production device and a gas using device which respectively correspond to the large blast furnace, the large coke oven and the large generator set suddenly breaks down and stops producing and using gas, the pressure of the whole gas pipe network is suddenly changed due to the change of the gas produced and used by the large equipment. Under the condition, the gas chamber is influenced by the pressure fluctuation of the gas pipe network, so that the lifting speed of the gas chamber piston is overlarge. If the lifting speed of the piston in the gas chamber exceeds the allowable range, accidents of the gas chamber equipment are easily caused.
In order to reduce the risk of operating the gas holder, the inventors propose the following example to improve.
Referring to fig. 1, fig. 1 is a schematic diagram illustrating a relationship between a gas tank and a gas pipe network according to an embodiment of the present disclosure.
As shown in fig. 1, a communication valve C is arranged between the gas cabinet a and the gas pipe network B. The communicating valve C is connected with the gas chamber A through a gas communicating pipe.
A movable piston D is arranged in the gas chamber A. The dashed arrows in fig. 1 may indicate the movable direction of the piston.
Based on the scenario shown in fig. 1, when the communication valve C is opened, if the pressure of the gas pipe network B is higher than the gas storage pressure of the gas tank a, the gas in the gas pipe network B enters the gas tank a (below the piston D in fig. 1), the piston D rises, and the gas tank a sucks gas from the gas pipe network B to reduce the pipe network pressure. If the pressure of the gas pipe network B is lower than the storage pressure of the gas tank A, the piston D descends, and the gas tank A supplies gas to the gas pipe network B so as to improve the pressure of the gas pipe network.
The communication valve D can be used as a control object in the gas holder operation control method provided in the embodiment of the present application.
The gas chamber A can be a thin oil gas chamber A, compared with a common gas chamber A, the thin oil gas chamber A has higher operating pressure, and the thin oil gas chamber A is adopted to stabilize the pressure of the gas pipe network B, so that the gas utilization rate can be improved, and the energy consumption can be reduced.
In one example, the gas cabinet a includes a floor, side panels, and a cabinet top. A piston D is arranged between the cabinet top and the bottom plate. And oil grooves are respectively arranged at the edge positions of the piston D and the bottom plate. The oil groove at the piston is marked as a piston oil groove, and the oil groove at the bottom plate is marked as a bottom oil groove. An oil pump station and a prepared oil tank are arranged outside the shell of the gas holder, and the oil pump station and the prepared oil tank are connected through an oil pipe.
In the prior art, a gas cabinet and a gas pipe network are usually communicated, and under the condition that a communication valve is fully opened, in the grid-connected operation process of the gas cabinet, various complex operation state parameters and process parameters of the gas cabinet are monitored in an artificial monitoring mode, and by combining the experience of operators of the gas cabinet and the safe operation rules of the gas cabinet, when some parameters are judged to exceed the safe operation standard range of the gas cabinet, manual intervention is performed, so that the communication valve between the gas cabinet and the gas pipe network is adjusted.
In the embodiment of the application, some parameters of the gas chamber are detected and analyzed, and based on different states of the gas chamber, a scheme capable of automatically controlling the communication valve is provided, so that on one hand, the gas chamber can be automatically put into/out of a grid-connected operation mode, on the other hand, in the grid-connected operation process of the gas chamber, the piston operation track and the piston operation parameters of the gas chamber can be pre-judged, and the opening degree of the communication valve can be adjusted according to the prediction result. Thereby reducing the requirements for workers and reducing the operation risk of the gas tank.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for controlling operation of a gas tank according to an embodiment of the present disclosure. The method can be applied to a monitoring system.
As shown in fig. 2, the method includes: S21-S24.
The method comprises the steps of S21-S22, wherein when the gas tank capacity is too high or too low, the system automatically and fully opens or fully closes the communication valve to automatically put the gas tank into or out of a grid-connected operation mode. S23-S24 provide a method by which the system can automatically fully open or fully close the on-line valve to automatically engage or disengage the gas cabinet from the on-line mode of operation under normal cabinet conditions.
S21: when the gas chamber capacity is detected to be increased to a first threshold value or when the gas chamber capacity is detected to be decreased to a second threshold value, the gas chamber is determined to enter an abnormal chamber capacity state, and a communication valve between the gas chamber and a gas pipe network is closed, so that the gas chamber exits a grid-connected operation mode.
In this embodiment, when the gas tank capacity exceeds the first threshold, the gas tank is considered to be in the high tank capacity state. And when the tank volume of the gas tank is lower than the second threshold value, the gas tank is considered to be in a low tank volume state. The high cabinet capacity state and the low cabinet capacity state are both regarded as abnormal cabinet capacity states. The volume of the space below the piston can be represented by the cabinet volume, the height of the space below the piston can be represented by the cabinet position, and the handling and storage conditions of the gas cabinet for the gas can be reflected by the cabinet volume and the cabinet position.
In one example, the distance between the piston and the highest stroke point of the piston of the gas holder is recorded as a first distance, the distance between the piston and the holder bottom of the gas holder is recorded as a second distance, the sum of the first distance and the second distance is recorded as a total distance value, and the holder capacity (or holder position) change of the gas holder can be reflected according to the ratio relation among the first distance, the second distance and the total distance value. The first threshold may be 80%, 85%, 90% of the total gas holder interior volume equivalent and the second threshold may be 10%, 15%, 20% of the total gas holder interior volume equivalent. The method provided by the present application will be described below by taking the first threshold and the second threshold as 90% and 10% of the entire internal space of the cabinet as examples.
When the gas chamber is detected to enter the abnormal chamber capacity state from the normal chamber capacity state, S21 can be executed, so that when the chamber capacity reaches the high chamber capacity (90%) or the low chamber capacity (10%), the on-line valve is controlled to be closed, and the gas chamber automatically exits the on-line grid-connected operation mode. Based on S21, accidents such as piston top rushing and piston bottom falling caused by the fact that the communication valve is not closed in time when the gas holder is in a high holder capacity state and a low holder capacity state can be avoided.
When the gas tank entering the abnormal tank capacity state exits the grid-connected operation mode, S22 may be executed.
S22: and when the gas tank exits the grid-connected operation mode and is in an abnormal tank capacity state, if the pressure of the gas pipe network is detected to meet the grid-connected operation input condition of the gas tank, the communication valve is opened so that the gas tank enters the grid-connected operation mode.
When the pressure of the gas pipe network reaches the grid-connected operation input condition of the gas cabinet, the monitoring system can automatically open the communication valve, so that the gas cabinet is input into grid-connected operation. When S22 is executed after S21, the gas holder in the abnormal holder capacity state can be put into grid-connected operation again.
In one embodiment, when the gas tank is in a low tank volume state, if the pressure of the gas pipe network is detected to be greater than the storage pressure of the gas tank, the monitoring system opens the communication valve, so that the gas tank is put into grid-connected operation. At the moment, the gas tank swallows gas from the gas pipe network, so that the pressure of the pipe network is reduced, the tank position of the gas tank is improved, the tank capacity is increased, and online grid-connected operation is realized.
In another embodiment, when the gas tank is in a high tank capacity state, if the pressure of the gas pipe network is detected to be lower than the storage pressure of the gas tank, the monitoring system opens the communication valve, so that the gas tank is put into grid-connected operation. At the moment, the gas cabinet discharges the gas in the cabinet, the gas is supplied to the gas pipe network, the cabinet position of the gas cabinet is reduced, the cabinet capacity is reduced, and online grid-connected operation is realized.
When the tank capacity (level) of the gas tank does not exceed the first threshold value and is not lower than the second threshold value, S23 is performed.
S23: and when the gas chamber capacity is between the first threshold value and the second threshold value, determining that the gas chamber is in a normal chamber capacity state, and if the piston operation parameters of the gas chamber are detected to meet grid-connected operation exit conditions, closing the communication valve so as to enable the gas chamber to exit the grid-connected operation mode in the normal chamber capacity state.
Among them, there are various piston operation parameters of the gas holder. The piston operating parameters of the gas holder may include: the piston inclination, the piston lifting speed, the oil level of the piston oil groove, the carbon monoxide concentration above the piston and the piston clamping stagnation mark position. The piston clamping stagnation zone bit is used for indicating whether the gas holder is in a piston clamping stagnation state, piston clamping stagnation time and the like. The specific manner in which the operating parameters of the individual pistons of the gas holder are obtained should not be construed as limiting the application.
Under the condition that the safe operation standard range corresponding to each piston operation parameter of the gas chamber is preset, when any one of the piston operation parameters of the gas chamber exceeds the safe operation standard range allowed by the gas chamber, the piston operation parameter of the gas chamber can be regarded as meeting grid-connected operation exit conditions.
When the gas chamber is in a normal chamber capacity state (the chamber capacity is between 10% and 90%), and the piston operation parameters of the gas chamber are determined to reach the grid-connected operation exit condition of the gas chamber, the monitoring system can completely close the communication valves, so that the automatic exit grid-connected operation in the normal chamber capacity state is realized.
In one example, when the gas holder is in a normal holder capacity state in the operation process, if the monitoring system detects that any one of piston operation parameters such as piston oil level, piston inclination, piston lifting speed, piston rising carbon monoxide concentration, piston clamping stagnation amount and the like of the gas holder exceeds a set normal operation standard range, an alarm prompt of 'piston operation parameter abnormity' can be output, a closing instruction of 'exiting grid-connected operation' is output to close a communication valve between the gas holder and a gas pipe network, and the gas holder automatically exits the grid-connected operation.
After the gas tank in the normal tank capacity state exits the grid-connected operation mode, S24 may be executed.
S24: and when the gas chamber is detected to be in the range between the first threshold value and the second threshold value and all the piston operation parameters of the gas chamber meet the grid-connected operation input condition, the communication valve is opened, so that the gas chamber in the normal chamber capacity state enters the grid-connected operation mode again.
Under the condition that the piston operation parameters of the gas chamber are various, when each piston operation parameter of the gas chamber accords with the safe operation standard range allowed by the gas chamber, the piston operation parameters of the gas chamber can be regarded as meeting grid-connected operation input conditions. It will be appreciated that the range of safe operating criteria for each parameter is different.
In one example, when the gas holder is in a state of exiting grid-connected operation and is in a normal holder capacity state, if the monitored piston operation parameters include 6 parameters of a piston oil level, a piston inclination, a piston lifting speed, a carbon monoxide concentration above the piston and a piston clamping stagnation amount, when the monitored 6 parameters all meet a set normal operation standard range, the grid-connected operation input condition can be met, the monitoring system generates an opening instruction of inputting grid-connected operation, and the communication valve is opened to realize grid-connected operation.
When the gas chamber is in a normal chamber capacity state (the chamber capacity is between 10% and 90%), and the piston operation parameters of the gas chamber reach the grid-connected operation input condition of the gas chamber, the monitoring system can fully open the communication valve, so that automatic input grid-connected operation in the normal chamber capacity state is realized.
Through the implementation mode of the S24, the gas tank in the normal tank capacity state can be put into grid-connected operation again at a proper time, and compared with a manual control mode, the method has higher processing efficiency.
Regarding the above-mentioned S23-S24, when it is detected that the piston operation parameter of the gas holder exceeds the allowable safe operation standard range of the gas holder, it is determined that the gas holder is faulty, and at this time, the monitoring system may turn the on-off valve all off, and the gas holder automatically exits the on-grid operation mode. When all the piston operation parameters of the gas chamber are detected to be in accordance with the safe operation standard range allowed by the gas chamber, the fault of the gas chamber can be determined to be repaired (no fault exists), at the moment, the monitoring system can fully open the communication valve, and the gas chamber automatically enters a grid-connected operation mode.
In the method of S21-S24, the gas chamber can be measured by a mechanical position transducer, an isolation amplifier and a chamber indicator as a way of measuring the chamber. When the piston moves up and down, the tank volume of the gas tank changes. As another implementation mode for measuring the cabinet volume, the distance between the piston and the top of the gas cabinet can be detected by ultrasonic waves and laser, so that the cabinet volume of the gas cabinet is obtained.
Wherein, the tank capacity of the gas tank can be regarded as a process operation parameter of the gas tank. In one example, the process operating parameters of the gas cabinet may include: the gas cabinet volume, the piston down pressure, the gas temperature, the pressure and the flow of the gas pipe network. The specific manner in which the various process operating parameters are obtained should not be construed as limiting the application.
By the method, the method for automatically switching the gas tank into/out of the grid-connected operation mode is provided. Wherein, the gas cabinet is compared with two threshold values to determine whether the gas cabinet is too high or too low. When the tank capacity is too high or too low, the gas tank is considered to be in an abnormal tank capacity state, and the communication valve between the gas tank and the gas pipe network is closed, so that the gas tank automatically exits from a grid-connected operation mode when entering the abnormal tank capacity state, and accidents such as piston top rushing and piston bottom falling caused by manual control untimely can be avoided. Under the condition that the cabinet capacity is too high or too low, the communication valve can be opened again based on the pressure monitoring of the gas pipe network, so that the gas cabinet exiting from the grid-connected operation mode can be automatically restored to the grid-connected operation mode. And when the gas tank is determined to have the normal tank capacity, whether the communication valve is to be closed is determined according to the piston operation parameters. In the method, the tank capacity of the gas tank, the pressure of a gas pipe network and the piston operation parameters are comprehensively considered, the gas tank is automatically put into/out of grid-connected operation in different scenes, the labor intensity of workers can be reduced, and the operation risk of the gas tank can be reduced.
Optionally, as shown in fig. 3, when the gas tank is in the grid-connected operation mode, the method may further include steps S25-S26. S25-S26 provide an implementation mode that the opening degree of the communication valve can be automatically adjusted in the grid-connected operation process of the gas holder.
S25: and in the grid-connected operation process of the gas tank, generating an adjusting instruction according to the historical operation parameters of the gas tank and the current pressure of the gas pipe network.
As an implementation of S25, as shown in fig. 4, S25 includes the sub-steps of: S251-S252.
S251: and predicting the piston running state of the gas tank at the next moment according to the historical running parameters of the gas tank and the current pressure of the gas pipe network.
Wherein S251 may include: S2511-S2512.
S2511: and obtaining a correlation analysis result between the full-stroke piston operation state of the gas chamber and the pressure data of the gas pipe network according to the historical operation parameters of the gas chamber, wherein the correlation analysis result is used as a first analysis result.
S2512: and predicting the piston running state of the gas tank at the next moment according to the current pressure of the gas pipe network and the first analysis result.
The monitoring system can analyze historical operation data of the gas holder (including historical process operation parameters and historical piston operation parameters of the gas holder), comprehensively analyze the relation among the holder position of the gas holder, the pressure of a gas pipe network and piston operation parameters (oil level, inclination, lifting speed, carbon monoxide concentration, piston clamping stagnation and the like) based on the historical operation data to obtain a group of relation curves, and accordingly obtain a correlation analysis result between the full-stroke piston operation state of the gas holder and the pressure data of the gas pipe network to serve as a first analysis result. Full stroke means that the moving path of the piston comprises the stroke from the highest stroke point of the piston of the gas holder to the bottom of the holder or from the bottom of the holder to the highest stroke point of the piston. The expression form of the first analysis result may be a relational curve, an array, or a relational expression obtained by fitting based on the relational curve and the array, and the like.
Under the condition of obtaining the first analysis result, the piston running state corresponding to a certain pressure value of the gas pipe network can be determined (when the opening degree of the communication valve is unchanged). For example, from the first analysis result, it can be known that when the pressure of the gas pipe network is b1, the corresponding piston operating state is: the piston ascends to d1, or the piston moving speed reaches v 1.
Based on the principle, under the condition that a first analysis result is obtained, the piston running state of the gas holder at the next moment is obtained through prediction according to the currently obtained pressure value of the gas pipe network.
In the embodiment of the application, the piston operation state of the gas tank at the next moment is represented by the piston operation parameter of the gas tank at the next moment. And when the prediction result indicates that abnormal piston operation parameters exist in the piston operation parameters of the gas tank at the next moment, the gas tank is considered to be about to have equipment failure. The abnormal piston operating parameter may also be referred to as an abnormal state parameter of the piston.
Through the implementation of the S2511-S2512, an implementation mode capable of predicting the piston running condition of the gas holder is provided.
If the piston operation state of the gas holder at the next time is predicted, S252 is executed.
S252: and generating the adjusting instruction according to the predicted piston running state of the gas tank at the next moment.
In an application scenario, when the piston rises at a speed v1 at the next moment according to the current pressure prediction of the gas pipe network and the current piston position is determined to be close to the cabinet top, an adjusting instruction can be generated to reduce the opening degree of the communication valve and prevent the piston from moving to the cabinet top at an excessively high speed.
Compared with the mode of performing post control after a fault is found, the implementation mode of S251-S252 can analyze and predict the relevant parameters of the gas chamber, predict the running condition of the piston of the gas chamber, and timely generate an adjusting instruction for adjusting the communication valve according to the predicted result, so that the fault occurrence probability of the gas chamber can be reduced, and the running risk of the gas chamber is reduced.
Wherein, S252 may include: S2521-S2522.
S2521: and obtaining a correlation analysis result among the pressure data of the gas pipe network, the opening value of the communicating valve and the abnormal state parameter of the piston according to the historical operating parameters of the gas cabinet, and taking the correlation analysis result as a second analysis result.
S2522: and when the predicted piston running state of the gas holder at the next moment comprises the abnormal state parameters of the piston, generating the adjusting instruction according to the second analysis result.
The monitoring system can analyze historical operation data of the gas holder (including historical process operation parameters and historical piston operation parameters of the gas holder), comprehensively analyze the relationship among the pressure of the gas pipe network, the opening degree of the communicating valve and the piston operation parameters (the height of an oil level, the gradient, the lifting speed, the piston clamping stagnation amount and the like) based on the historical operation data, perform correlation analysis on different opening degrees of the communicating valve and the abnormal state parameters of the piston by combining the pressure of the current gas pipe network to obtain a group of relation curves, and obtain correlation analysis results among the pressure data of the gas pipe network, the opening degree of the communicating valve and the abnormal state parameters of the piston as second analysis results. The expression form of the second analysis result can be a relational curve, an array or a relational expression obtained by fitting based on the relational curve and the array.
Under the conditions of obtaining the pressure of the current gas pipe network and predicting the piston running state of the gas cabinet at the next moment, a certain pressure value of the gas pipe network and the opening value of the communicating valve corresponding to one piston running state can be determined based on a second analysis result obtained by analysis.
Based on this principle, from the second analysis result, it can be known that when the pressure of the gas pipe network is b1 and the piston moving speed reaches v1, the opening value of the corresponding communication valve is k 1. And generating an adjusting instruction based on the obtained k 1. Therefore, an adjusting instruction for adjusting the opening degree of the communication valve can be automatically generated based on the prediction result, and the communication valve can be adjusted (the valve is closed) in advance by adjusting the opening degree of the communication valve based on the adjusting instruction, so that the piston operation parameters are in the safe operation standard range, and the safe operation of the gas holder is guaranteed. And it is advantageous to enable the piston that has entered the abnormal state (for example, the piston that has moved too fast can be regarded as entering the abnormal state) to return to the normal state as soon as possible.
Through the implementation mode of S2521-S2522, after historical data of the gas holder are analyzed, a second analysis result is obtained, an adjustment instruction is generated based on the predicted piston operation condition and the second analysis result, the opening degree of the communication valve is adjusted based on the adjustment instruction, and the condition that the piston operation state parameters exceed the safe operation standard allowed by the gas holder under the condition that the communication valve is fully opened can be avoided.
S26: and adjusting the opening degree of the communication valve according to the adjusting instruction.
The adjusting instruction comprises a control parameter for adjusting the opening degree of the communicating valve.
Through the implementation mode of the S25-S26, the opening degree of the communicating valve can be adjusted in time in the grid-connected operation process of the gas cabinet, the operation risk of the gas cabinet can be reduced, and the influence of artificial regulation and control hysteresis on the safe operation of the gas cabinet can be avoided.
Optionally, when the gas tank is in the grid-connected operation mode, as shown in fig. 5, the method may further include step S27. When the piston jamming phenomenon is detected, the gas tank is enabled to exit the grid-connected operation mode by controlling the communication valve to be closed through S27.
S27: and in the process that the gas tank supplies gas to the gas pipe network or in the process that the gas tank sucks gas from the gas pipe network, if the piston clamping stagnation phenomenon of the gas tank is detected, the communication valve is closed.
For example, the piston sticking measurement mode may be: and comparing the measured piston down pressure with the designed operating pressure range of the gas chamber, and if the measured piston down pressure is lower than the designed operating pressure range lower limit of the gas chamber, or if the measured piston down pressure is higher than the designed operating pressure range upper limit of the gas chamber, determining that the piston clamping stagnation phenomenon occurs.
When the piston jamming phenomenon is determined to occur, the piston jamming flag bit is a valid word bit, and can be set to be 1, 0 and the like, for example. When the piston clamping stagnation phenomenon is determined, the time of the piston in the piston clamping stagnation state can be counted.
Through the implementation mode of the S27, when the piston clamping stagnation phenomenon is detected, the communication valve is closed, and the potential safety hazard caused by continuous gas supply or gas suction of the gas chamber under the piston clamping stagnation condition can be reduced.
Optionally, as shown in fig. 6, the method may further include steps S20 and S28.
S20: and in the grid-connected operation process of the gas chamber, acquiring the piston operation parameters of the gas chamber and the process operation parameters of the gas chamber.
S28: and when detecting that the piston operation parameters or the process operation parameters of the gas chamber exceed the safe operation standard range of the gas chamber, giving an alarm for prompting.
S28 may be used in combination with S23, for example, when it is detected that a piston operation parameter of the gas tank exceeds a safe operation standard range of the gas tank, an alarm is given, and it is determined that a grid-connected operation exit condition is satisfied at this time, the communication valve is closed, so that the gas tank exits the grid-connected operation mode.
Through the implementation mode of the S28, the on-duty personnel of the gas chamber can find out abnormal conditions of the gas chamber in time.
Optionally, when it is determined that the tank volume of the gas tank exceeds the first threshold, an alarm prompt content indicating the current tank volume may be output.
Optionally, when it is determined that the tank volume of the gas tank is lower than the second threshold, an alarm prompt content indicating that the current tank volume is low may be output.
Optionally, when a certain operating parameter of the piston of the gas holder is abnormal, an alarm prompt content for indicating that the current holder holds the abnormal operating parameter can be output.
In this application embodiment, when needing control UNICOM's valve to open, monitored control system can generate the instruction of opening for open the UNICOM's valve. When it is desired to control the closing of the communication valve, the monitoring system may generate a closing command to close the communication valve.
