When the coke oven has a fault, the exchanger control device of the embodiment of the application firstly acquires the real-time position of the cock of the coal cylinder 25 and/or the waste gas cylinder 27 through the analog quantity input module 11, and then the controller 15 controls the driving module 13 according to the real-time position of the cock of the coal cylinder 25 and/or the waste gas cylinder 27 so as to close the coal cylinder 25 and/or the waste gas cylinder 27. Therefore, when the coke oven fails, the exchanger control device of the embodiment of the application can automatically acquire the real-time positions of the cocks of the coal cylinder 25 and/or the waste gas cylinder 27; the drive module 13 can then be controlled by the controller 15 in order to be able to automatically close the gas cylinder 25 and/or the waste gas cylinder 27.

In addition, the situation that when the coke oven fails, the exchanger is immediately powered off to cause the coal cylinder 25 and the waste gas cylinder 27 to be kept in place and have potential safety hazards can be avoided by closing the coal cylinder 25 and the waste gas cylinder 27 of the coke oven.
As shown in fig. 1, in the present embodiment, the analog input module 11 is used for collecting analog quantity. The analog quantity is a quantity in which a variable continuously changes within a certain range. I.e. can take any value (within a range of values) within a certain range (domain of definition).
In this embodiment, the analog input module 11 is used to capture the real time position of the stopcocks of the coal cylinder 25 and/or the exhaust cylinder 27. In other words, the analog quantity collected by the analog quantity input module 11 is the real-time position of the cock of the gas cylinder 25 and/or the waste gas cylinder 27. Further, the analog input module 11 may be used to obtain the real-time position of the tap of the coal cylinder 25 and the real-time position of the tap of the exhaust cylinder 27. The analog input module 11 may also be used to select one of the real time position of the tap of the gas cylinder 25 and the real time position of the tap of the waste cylinder 27 for acquisition.
In one embodiment, the switch control apparatus provided in the embodiment of the present application further includes: and the first detection device 21 and the second detection device 23 are connected with the analog quantity input module 11, the first detection device 21 is arranged on the coal cylinder 25, the first detection device 21 is used for detecting the real-time position of the cock of the coal cylinder 25, the second detection device 23 is arranged on the waste cylinder 27, and the second detection device 23 is used for detecting the real-time position of the cock of the waste cylinder 27. So that the analog input module 11 can acquire the real-time position of the cock of the coal cylinder 25 from the first detecting device 21 after the first detecting device 21 detects the real-time position of the cock of the coal cylinder 25. When the second detecting means 23 detects the real-time position of the cock of the degassing cylinder 27, the analog input module 11 can acquire the real-time position of the cock of the degassing cylinder 27 from the second detecting means 23.
Further, the first detecting device 21 and the second detecting device 23 are both displacement sensors. The first detection means 21 can thus detect the displacement of the cock of the coal cylinder 25 by means of the displacement sensor. I.e. the real time position of the tap of the gas cylinder 25 detected by the first detection means 21 is the real time displacement of the tap of the gas cylinder 25 by means of the displacement sensor. The displacement of the cock of the exhaust cylinder 27 can be detected by the displacement sensor second detecting means 23. I.e. the real time position of the tap of the exhaust cylinder 27 detected by the second detection means 23 is the real time displacement of the tap of the exhaust cylinder 27 by means of the displacement sensor.
In this embodiment, the drive module 13 is used to drive the movement of the coal cylinder 25 and/or the waste cylinder 27 cock. I.e. the drive module 13 may be used to drive the movement of the tap of the coal cylinder 25 and the movement of the tap of the exhaust cylinder 27. The drive module 13 may also be used to select one of the gas cylinder 25 tap and the waste cylinder 27 tap for driving.
Further, the driving module 13 is a switching value output module. The switching value is a discontinuous variable. Further, the switching value has two states of 1 and 0. The 1 and 0 can refer to the opening and closing of a circuit or the opening and closing of contacts, or the opening and closing in a digital circuit. The switching value output is an output 0 or 1 for controlling the on or off of an external device. So that the external device can be turned on or off through the switching value output module. Further, the switching value output module is used for enabling an existing switching value output channel structure to be adopted, and the application is not limited thereto.
In the present embodiment, the controller 15 is connected to the analog input module 11 and the driving module 13, respectively. The controller 15 is thus able to obtain the real time position of the taps of the gas cylinder 25 and/or the waste cylinder 27 in the analog input module 11. Specifically, the analog input module 11 is connected to the controller 15 through a communication bus 35. The drive module 13 is connected to the controller 15 via a communication bus 35. Further, the controller 15 is adapted to control the drive module 13 to switch off the coal cylinder 25 and/or the exhaust cylinder 27 depending on the real time position of the taps of the coal cylinder 25 and/or the exhaust cylinder 27. The drive module 13 is thus controlled by the controller 15 such that the drive module 13 can automatically close the gas cylinder 25 and/or the waste gas cylinder 27. The switch control device according to the embodiment of the present invention can close the coal cylinder 25 and/or the waste gas cylinder 27 in time when the coke oven is out of order, and does not require manual operation to close the coal cylinder 25 and the waste gas cylinder 27 of the coke oven.
Specifically, the controller 15 first determines a predetermined direction of movement of the coal cylinder 25 and/or exhaust cylinder 27 cock based on the real-time position of the coal cylinder 25 and/or exhaust cylinder 27 cock, and then the controller 15 controls the drive module 13 such that the coal cylinder 25 and/or exhaust cylinder 27 cock moves in the predetermined direction until the coal cylinder 25 and/or exhaust cylinder 27 cock is closed.
Further, the controller 15 is a PLC controller 15, but the controller 15 is not limited to the PLC controller 15, and may be other intelligent control devices, such as a computer. Further, the controller 15 is also connected to a power supply 31 and an ethernet 33, respectively. The ethernet 33 may be connected to a corresponding microcomputer on the control platform for control by the operator.
In one embodiment, the switch control apparatus provided in the embodiment of the present application further includes: and a switching value input module 19. The switching value input module 19 is connected to the controller 15. Specifically, the switching value input module 19 is connected to the controller 15 through a communication bus 35. The switching value input module 19 is used for acquiring the switching value of the coal cylinder 25 and/or the waste gas cylinder 27. The open state of the gas cylinder 25 can thus be indicated by 0 or 1 by means of the switching variable input module 19. And the closed state of the gas cylinder 25 can be represented by 0 or 1 through the switching value input module 19. The open state of the exhaust cylinder 27 can be indicated by 0 or 1 by the switching variable input module 19. And the off state of the off cylinder 27 can be represented by 0 or 1 by the switching value input module 19. So that the controller 15 can acquire the open or closed state of the coal cylinder 25 through the switching amount input module 19. Further, the switching value input module 19 is used to input the available switching value into the channel structure, and the application is not limited thereto.
Further, the controller 15 is also used to control the driving module 13 according to the switching amount of the coal cylinder 25 and/or the exhaust cylinder 27, so that the driving module 13 can drive the coal cylinder 25 and/or the exhaust cylinder 27 cock to move according to a predetermined rule. The predetermined rule may be to actuate the cock of the coal cylinder 25 to move to close the coal cylinder 25. The cock of the exhaust cylinder 27 is then driven to move to exchange exhaust gas and air. Finally, the cock of the coal cylinder 25 is driven to move to open the coal cylinder 25. So that the gas flow direction of the gas, air and exhaust gas can be reversed by the predetermined rule.
In one embodiment, the switch control apparatus provided in the embodiment of the present application further includes: switching value input detection means. One end of the switching value input detection device is connected with the gas cylinder 25 and/or the waste gas cylinder 27, and the other end of the switching value input detection device is connected with the switching value input module 19. The switching value input detection device is used for detecting the switching value of the coal gas cylinder 25 and/or the waste gas cylinder 27 and uploading the switching value of the coal gas cylinder 25 and/or the waste gas cylinder 27 to the switching value input module 19.
Further, the switching value input detecting means is connected to the switching value input module 19 through a relay. Thereby preventing currents of different voltage levels from entering the switching value input module 19.
In one embodiment, the switch control apparatus provided in the embodiment of the present application further includes: switching value output detection means. One end of the switching value output detection device is connected with the gas cylinder 25 and/or the waste gas cylinder 27, and the other end of the switching value output detection device is connected with the switching value output module. The switching value output detection device is used for detecting the switching value of the coal gas cylinder 25 and/or the waste gas cylinder 27 and uploading the switching value of the coal gas cylinder 25 and/or the waste gas cylinder 27 to the switching value output module.
Further, the switching value output detection device is connected with the switching value output module through a relay. Thereby preventing the current of different voltage levels from entering the switching value output module.
In one embodiment, the switching value input module 19 is also used to acquire the switching value of the emergency stop mechanism 29. Wherein the scram mechanism 29 is used for operation when the switch needs to be stopped. The switch is required to stop running, and the switch can be used for stopping running when a coke oven has faults, such as insufficient supply of heating gas of the coke oven, accidental closing of a flue gate, insufficient suction caused by tripping of a pressurizing fan of a flue gas desulfurization system, and the like. Of course, the need to stop the exchange is not limited to the case where the coke oven is out of order, and the need to stop the exchange may be other cases, and the present application is not limited thereto. The emergency stop mechanism 29 may be an emergency stop button. So that the emergency stop mechanism 29 can be activated by pressing the emergency stop button manually or by mechanical means when it is desired to stop the switch. Accordingly, the scram mechanism 29 is not triggered when the scram button is not pressed.
Further, when the scram mechanism 29 is not activated, the controller 15 controls the driving module 13 according to the switching amount of the coal cylinder 25 and/or the exhaust cylinder 27 so that the driving module 13 can drive the plug of the coal cylinder 25 and/or the exhaust cylinder 27 to move according to a predetermined rule. That is, when there is no need to stop the operation of the exchanger or the exchanger is normally operated without a malfunction or other urgent event, the controller 15 controls the driving module 13 so that the exchanger can reverse the gas flow direction of gas, air and exhaust gas by the driving of the driving module 13.
Further, when the scram mechanism 29 is triggered, the controller 15 controls the drive module 13 to turn off the coal cylinder 25 and/or the exhaust cylinder 27 according to the real-time position of the cock of the coal cylinder 25 and/or the exhaust cylinder 27. I.e. when it is desired to stop the switch, or a malfunction or other emergency occurs in the switch, the controller 15 controls the drive module 13 so that the switch can shut down the coal cylinder 25 and/or the exhaust cylinder 27 by the driving of the drive module 13. This makes it possible, on the one hand, to switch off the coal cylinders 25 and/or the waste gas cylinders 27 in a timely manner in the event of a coke oven failure, and does not require manual operation for switching off the coal cylinders 25 and the waste gas cylinders 27 of the coke oven. On the other hand, the situation that when the coke oven fails, the exchanger is immediately powered off to cause the coal cylinder 25 and the waste gas cylinder 27 to be kept in place and have potential safety hazards can be avoided by closing the coal cylinder 25 and the waste gas cylinder 27 of the coke oven.
As shown in fig. 2, the present embodiment also provides a control method using the above-described switch control device, including: step S11: the analog quantity input module 11 acquires the real-time position of the cock of the coal cylinder 25 and the real-time position of the cock of the waste cylinder 27; step S13: the controller 15 controls the drive module 13 according to the real-time position of the coal cylinder 25 cock; step S15: the driving module 13 drives the coal cylinder 25 cock to move until the coal cylinder 25 cock moves to a first middle limit position; wherein the first middle position is the position of the cock of the coal cylinder 25 when the coal cylinder 25 is closed; step S17: after the coal cylinder 25 is turned off, the controller 15 controls the driving module 13 according to the real-time position of the cock of the waste cylinder 27; step S19: the driving module 13 drives the waste air cylinder 27 cock to move until the waste air cylinder 27 cock moves to a second middle limit position; wherein the second middle limit is a position where the cock of the degassing cylinder 27 is located when the degassing cylinder 27 is turned off.
According to the control method of the exchanger control device of the embodiment of the application, when the coke oven has a fault, the real-time positions of the cocks of the coal cylinder 25 and the waste gas cylinder 27 can be automatically acquired; the drive module 13 can then be controlled by the controller 15 to automatically close the coal cylinder 25 and the exhaust cylinder 27 in turn. The switch control device according to the embodiment of the present invention can close the coal cylinder 25 and the waste gas cylinder 27 in time when the coke oven is out of order, and does not need to close the coal cylinder 25 and the waste gas cylinder 27 of the coke oven by manual operation. In addition, the situation that when the coke oven fails, the exchanger is immediately powered off to cause the coal cylinder 25 and the waste gas cylinder 27 to be kept in place and have potential safety hazards can be avoided by closing the coal cylinder 25 and the waste gas cylinder 27 of the coke oven.
In the present embodiment, step S11: the analog input module 11 acquires the real-time position of the cock of the coal cylinder 25 and the real-time position of the cock of the exhaust cylinder 27. Specifically, first, the first detecting device 21 detects the real-time position of the cock of the coal cylinder 25. The second detection means 23 detects the real time position of the cock of the degassing cylinder 27. The analog input module 11 then obtains the real-time position of the gas cylinder 25 tap from within the first sensing device 21. And the analog input module 11 obtains the real-time position of the cock of the cylinder 27 from the second detecting means 23.
In the present embodiment, step S13: the controller 15 controls the drive module 13 according to the real time position of the coal cylinder 25 tap. Specifically, the controller 15 first determines the positional relationship of the cock of the coal cylinder 25 with the first middle position based on the real-time position of the cock of the coal cylinder 25. For example, the controller 15 determines whether the cock of the coal cylinder 25 is located on the left or right side of the first middle limit position. The controller 15 then determines the predetermined direction of movement of the cock of the coal cylinder 25 toward the first intermediate position based on the positional relationship of the cock of the coal cylinder 25 with the first intermediate position. For example, when the coal cylinder 25 cock is located to the left of the first middle position, the predetermined direction is to the right. That is, when the cock of the coal cylinder 25 is positioned at the left side of the first middle limit position, the driving module 13 drives the cock of the coal cylinder 25 to move rightwards to reach the first middle limit position. The predetermined direction is to the left when the coal cylinder 25 cock is to the right of the first middle position. That is, when the cock of the coal cylinder 25 is positioned at the right side of the first middle limit position, the driving module 13 drives the cock of the coal cylinder 25 to move leftwards, namely, the first middle limit position can be reached. The first middle limit is the position where the gas cylinder 25 cock is located when the gas cylinder 25 is closed. The controller 15 then controls the drive module 13 so that the coal cylinder 25 cock can be moved in a predetermined direction.
In the present embodiment, step S15: the drive module 13 drives the coal cylinder 25 cock to move until the coal cylinder 25 cock moves to a first intermediate position.
Specifically, for example, when the coal cylinder 25 cock is located at the left side of the first middle limit position, the driving module 13 drives the coal cylinder 25 cock to move rightward until the coal cylinder 25 cock stops moving when the first middle limit position is reached. Thereby shutting off the coal cylinder 25. When the coal cylinder 25 cock is located at the right side of the first middle limit position, the driving module 13 drives the coal cylinder 25 cock to move leftward until the coal cylinder 25 cock stops moving when the first middle limit position is reached. Thereby shutting off the coal cylinder 25.
In the present embodiment, step S17: after the gas cylinder 25 is shut off, the controller 15 controls the drive module 13 according to the real-time position of the cock of the waste gas cylinder 27. So that in the event of a coke oven failure, the controller 15 first shuts down the coal cylinder 25 and then shuts down the waste cylinder 27. Therefore, the coal gas in the coke oven can be completely combusted, thereby thoroughly eliminating the potential safety hazard of the coke oven.
Specifically, the controller 15 first determines the positional relationship of the cock of the waste cylinder 27 with the second middle limit position based on the real-time position of the cock of the waste cylinder 27. For example, the controller 15 determines whether the cock of the degassing cylinder 27 is located at the left or right side of the second middle limit position. The controller 15 then determines the predetermined direction in which the cock of the waste cylinder 27 moves toward the second middle limit position based on the positional relationship of the cock of the waste cylinder 27 with the second middle limit position. For example, when the cock of the degassing cylinder 27 is located at the left side of the second middle limit position, the predetermined direction is rightward. That is, when the cock of the degassing cylinder 27 is located at the left side of the second middle limit position, the driving module 13 drives the cock of the degassing cylinder 27 to move rightward, i.e., to reach the second middle limit position. The predetermined direction is to the left when the cock of the degassing cylinder 27 is located at the right side of the second middle limit position. That is, when the cock of the degassing cylinder 27 is located at the right side of the second middle limit position, the driving module 13 drives the cock of the degassing cylinder 27 to move leftward, i.e., the second middle limit position can be reached. The second middle limit is the position where the cock of the exhaust cylinder 27 is located when the exhaust cylinder 27 is closed. The controller 15 then controls the drive module 13 so that the cock of the waste cylinder 27 can be moved in a predetermined direction.
Further, the controller 15 controls the driving module 13 according to the real-time position of the cock of the waste cylinder 27 while waiting for a predetermined time after the gas cylinder 25 is turned off. Thus, in order to further ensure that the gas in the coke oven is completely burned, the controller 15 waits for a predetermined time after the gas cylinder 25 is closed. The predetermined time may be set according to actual production, and is not specified in this application.
In the present embodiment, step S19: the driving module 13 drives the cock of the waste air cylinder 27 to move until the cock of the waste air cylinder 27 moves to a second middle limit position; wherein the second middle limit is the position where the cock of the degassing cylinder 27 is located when the degassing cylinder 27 is closed.
Specifically, for example, when the cock of the waste cylinder 27 is located at the left side of the second middle limit position, the driving module 13 drives the cock of the waste cylinder 27 to move rightward until the movement of the cock of the waste cylinder 27 stops when the second middle limit position is reached. Thereby shutting off the waste cylinder 27. When the waste cylinder 27 cock is located at the right side of the second middle limit position, the driving module 13 drives the waste cylinder 27 cock to move leftward until the waste cylinder 27 cock stops moving when the second middle limit position is reached. Thereby shutting off the waste cylinder 27.
Further, the control method of the switch control device according to the embodiment of the present application further includes: the controller 15 acquires the switching value of the emergency stop mechanism 29; when the emergency stop mechanism 29 is triggered, the above-described steps of the controller 15 controlling the drive module 13 according to the real-time position of the cock of the coal cylinder 25 and the controller 15 controlling the drive module 13 according to the real-time position of the cock of the waste cylinder 27 after the coal cylinder 25 is turned off are performed.
I.e. when it is desired to stop the switch, or a malfunction or other emergency occurs in the switch, the controller 15 controls the drive module 13 according to the real-time position of the coal cylinder 25 tap; the driving module 13 drives the cock of the coal cylinder 25 to move until the cock of the coal cylinder 25 moves to a first middle limit position; wherein, the first middle limit is the position of the cock of the gas cylinder 25 when the gas cylinder 25 is closed; after the gas cylinder 25 is closed, the controller 15 controls the driving module 13 according to the real-time position of the cock of the waste gas cylinder 27; the driving module 13 drives the cock of the waste air cylinder 27 to move until the cock of the waste air cylinder 27 moves to a second middle limit position; wherein the second middle limit is the position where the cock of the degassing cylinder 27 is located when the degassing cylinder 27 is closed. This makes it possible, on the one hand, to switch off the coal cylinders 25 and/or the waste gas cylinders 27 in a timely manner in the event of a coke oven failure, and does not require manual operation for switching off the coal cylinders 25 and the waste gas cylinders 27 of the coke oven. On the other hand, the situation that when the coke oven fails, the exchanger is immediately powered off to cause the coal cylinder 25 and the waste gas cylinder 27 to be kept in place and have potential safety hazards can be avoided by closing the coal cylinder 25 and the waste gas cylinder 27 of the coke oven.
Further, when the scram mechanism 29 is not triggered, the controller 15 cyclically executes the following steps:
step S111: the controller 15 controls the driving module 13 so that the driving module 13 can drive the cock of the coal cylinder 25 to move, thereby turning off the coal cylinder 25. Specifically, the controller 15 controls the drive module 13 such that the drive module 13 can drive the coal cylinder 25 tap to move toward the first mid-limit position and stop the coal cylinder 25 tap at the first mid-limit position. So that the coal cylinder 25 can be shut off to prepare for exchanging exhaust gas and air through step S111.
Step S113: the controller 15 controls the driving module 13 so that the driving module 13 can drive the cock of the exhaust cylinder 27 to move, thereby exchanging exhaust gas and air. Specifically, the controller 15 controls the drive module 13 such that the drive module 13 can drive the cock of the degassing cylinder 27 to move away from the second middle position first to open the degassing cylinder 27. The controller 15 then controls the drive module 13 so that the drive module 13 can drive the waste cylinder 27 tap away towards the middle position to close the waste cylinder 27. That is, the waste cylinder 27 is first opened and then the waste cylinder 27 is closed in step S113, thereby achieving the exchange of the exhaust gas and the air.
Step S115: the controller 15 controls the driving module 13 so that the driving module 13 can drive the cock of the coal cylinder 25 to move, thereby opening the coal cylinder 25. Specifically, the controller 15 controls the drive module 13 such that the drive module 13 can drive the coal cylinder 25 tap to move away from the first mid-stop position. So that the coal cylinder 25 can be opened through step S115. That is, the coal cylinder 25 is opened after the step S113, so that the gas flow direction of the gas, air and exhaust gas is once reversed.
That is, when the emergency stop mechanism 29 is not triggered, the controller 15 enables the exchanger to continuously reverse the gas flow direction of the gas, air and exhaust gas by performing the steps S111, S113 and S115 in a loop.
