Description

Technical Field

[0001] The present invention relates to the technical field of monitoring of coking production equipment, and in particular, to a method and device for monitoring tube explosion of a coke dry quenching boiler and a storage medium. Background Art

[0002] The coke dry quenching technology is a widely used coke quenching technology in the coking industry, which refers to a coke quenching process method using inert gas to cool down red coke. In the actual production of a coke dry quenching boiler, the coke dry quenching waste heat boiler may have a tube explosion problem due to reasons such as service life, manufacturing defects, poor water quality of boiler water supply, defects in the material of the pipe, or corrosion of the pipe. Due to the high internal pressure and internal temperature of the waste heat boiler, it is difficult to directly monitor the tube explosion situation of the coke dry quenching boiler. Moreover, when the boiler has a tube explosion, it often starts from a small leak point at one place. As time goes by, the small leak point gradually becomes larger. Until the leak point affects the operation of the system, it will have a more obvious impact on the system. At this time, the shutdown for maintenance takes a long time. On the other hand, if the boiler is blindly shut down for maintenance before the tube explosion is determined, it will also affect the production capacity of the coke dry quenching boiler and cause economic losses. Summary of the Invention

[0003] The problem solved by the present invention is how to effectively monitor the tube explosion problem in the initial stage of the tube explosion.

[0004] To solve the above problems, the present invention provides a method for monitoring tube explosion of a coke dry quenching boiler, including:

[0005] Obtaining system internal parameters, where the system internal parameters include humidity; analyzing the system internal parameters to determine whether the coke dry quenching boiler system is in a normal operating state; if the coke dry quenching boiler system is not in the normal operating state, determining a corresponding preset treatment plan based on the system internal parameters.

[0006] Compared with the prior art, the present invention obtains system internal parameters, analyzes and determines whether the coke dry quenching boiler system is in a normal operating state, and determines that the coke dry quenching boiler system is not in a normal operating state when the system internal parameters are abnormal, so as to ensure that the system anomaly is discovered in the first time and actively intervened, effectively avoiding the further expansion of the tube explosion accident; after the system is not in a normal operating state, taking the humidity value as the main judgment basis, determining a corresponding preset treatment plan based on the system internal parameters, ensuring that the tube explosion of the boiler is discovered in the initial stage, avoiding the further expansion of the accident, providing sufficient time for preparation work, and at the same time greatly shortening the maintenance time.

[0007] Optionally, the analyzing the system internal parameters to determine whether the coke dry quenching boiler system is in a normal operating state includes:

[0008] Obtain the humidity; determine whether the humidity is greater than a first threshold; if the humidity is greater than the first threshold, then determine that the coke dry quenching boiler system is not in the normal operating state.

[0009] Thus, based on the first threshold of humidity, it can be determined whether the coke dry quenching boiler system is in the normal operating state.

[0010] Optionally, if the coke dry quenching boiler system is not in the normal operating state, then determining a corresponding preset processing scheme based on the internal parameters of the system includes:

[0011] Determine whether the humidity is greater than a third threshold, where the third threshold is greater than the first threshold; if the humidity is greater than the third threshold, then control the coke dry quenching boiler system and the induced draft fan to interlock and stop.

[0012] Thus, through the third threshold, it can be directly determined whether a serious pipe explosion accident has occurred, and by controlling the interlock shutdown of the coke dry quenching boiler system and the induced draft fan, it is ensured that the accident will not expand further and the safety of workers is guaranteed.

[0013] Optionally, if the coke dry quenching boiler system is not in the normal operating state, then determining a corresponding preset processing scheme based on the internal parameters of the system further includes:

[0014] Determine whether the humidity is greater than a second threshold, where the second threshold is greater than the first threshold and the second threshold is less than the third threshold; if the humidity is greater than the second threshold, then give an alarm and conduct a fault investigation.

[0015] Thus, after determining that the system is in an abnormal state, the second threshold is introduced to assist in judging whether an alarm is needed in the current situation, and a fault investigation is conducted to ensure that it is determined whether a pipe explosion accident has occurred in the first time.

[0016] Optionally, the internal parameters of the system further include the flue gas pressure, flue gas temperature, boiler liquid level, and hydrogen content in the pipeline of the coke dry quenching boiler system.

[0017] Thus, through the flue gas pressure, flue gas temperature, boiler liquid level, and hydrogen content in the pipeline, it is ensured to comprehensively and three-dimensionally judge whether there is an abnormality.

[0018] Optionally, analyzing the internal parameters of the system and determining whether the coke dry quenching boiler system is in the normal operating state further includes:

[0019] When at least one of the following situations occurs, determine that the coke dry quenching boiler system is not in the normal operating state:

[0020] The fluctuation range of the flue gas pressure is greater than a first preset range, the fluctuation range of the flue gas temperature is greater than a second preset range, the fluctuation range of the boiler liquid level is greater than a third preset range, and the hydrogen content in the pipeline is greater than a preset hydrogen threshold; if the coke dry quenching boiler system is not in the normal operating state, an alarm is given and a fault check is carried out.

[0021] Thus, by jointly judging the coke dry quenching boiler system's normal operating state through internal system parameters from different angles, the burst pipe accident can be detected in the first time.

[0022] Optionally, after analyzing the internal system parameters to determine whether the coke dry quenching boiler system is in the normal operating state, it further includes:

[0023] If the coke dry quenching boiler system is in the normal operating state, the internal system parameters are re-acquired after a preset interval time, and it is determined whether the coke dry quenching boiler system is in the normal operating state.

[0024] Thus, by continuously obtaining the internal system parameters, the parameter change situation of the system is ensured; continuously judging whether the coke dry quenching boiler system is in the normal operating state ensures that the burst pipe accident can be detected in the first time.

[0025] Optionally, the humidity includes the humidity at the inlet of the desulfurization reactor and the humidity at the chimney discharge port.

[0026] Thus, accurately obtaining the internal humidity of the system is ensured.

[0027] On the other hand, the present invention also provides a coke dry quenching boiler burst pipe monitoring device, including:

[0028] A detection module for acquiring internal system parameters, where the internal system parameters include humidity; an analysis module for analyzing the internal system parameters to determine whether the coke dry quenching boiler system is in the normal operating state; an execution module for, when the coke dry quenching boiler system is not in the normal operating state, determining a corresponding preset treatment plan based on the internal system parameters.

[0029] The beneficial effects of the coke dry quenching boiler burst pipe monitoring device of the present invention compared with the prior art are the same as those of the above-mentioned coke dry quenching boiler burst pipe monitoring method, and will not be elaborated here.

[0030] On the other hand, the present invention also provides a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, the above-mentioned coke dry quenching boiler burst pipe monitoring method is implemented.

[0031] The beneficial effects of the computer-readable storage medium of the present invention compared with the prior art are the same as those of the above-mentioned dry quenching coke boiler tube burst monitoring method, which will not be elaborated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] It should be noted that the modifications of "one" and "multiple" mentioned in the present invention are illustrative rather than restrictive. Those skilled in the art should understand that unless otherwise clearly specified in the context, it should be understood as "one or more".

[0040] The coke dry quenching boiler is an important part of the coke dry quenching system. Serving the boiler, it uses the high-temperature circulating gas that has absorbed the sensible heat of the red coke to exchange heat with desalted and deoxygenated pure water to generate steam at a rated temperature and pressure for power generation. During production, the boiler may experience a tube burst accident. A boiler tube burst often starts from a small leak point and is slowly eroded by the high-temperature and high-pressure steam of the waste heat boiler, resulting in the leak point tending to develop more and more and become larger, and it will slowly erode the adjacent pipes through the leak point, causing tube bursts in other pipes.

[0041] In the prior art, when the water vapor leakage accumulates to a certain extent, it will be recognized as a tube burst accident. At this time, the shutdown for maintenance may involve multiple leak points in multiple pipes, and the processing time is relatively long. During actual maintenance, for safety reasons, when a leak point is found, at least three pipes adjacent to the pipe where the leak point is located need to be blocked, which further increases the processing time, has an adverse impact on the stable operation of the coke dry quenching boiler, and also causes a certain economic loss.

[0042] As Figure 1 shown, a method for monitoring tube bursts in a coke dry quenching boiler provided by an embodiment of the present invention includes:

[0043] Step S100, obtaining system internal parameters, where the system internal parameters include humidity.

[0044] The system internal parameters refer to the internal parameters of various parts within the entire coke dry quenching boiler circulation system. During normal production, the coke dry quenching uses 170°C circulating flue gas to quench 1000°C red coke. During this process, the temperature of the coke is reduced. After being heated to 950°C, the circulating flue gas exchanges heat in the waste heat boiler to produce high-temperature and high-pressure steam at 9 MPa and 540°C for power generation. The 170°C circulating flue gas after heat exchange is transported back to the coke dry quenching furnace and reused repeatedly. During the circulation process of the circulating flue gas, the flue gas will burn in the high-temperature section, and coupled with the leakage in the negative pressure area of the circulation system, the amount of circulating flue gas will increase. Therefore, part of the flue gas needs to be discharged to achieve internal balance within the system.

[0045] The discharged flue gas (140°C - 200°C) from the coke dry quenching enters the SDS desulfurization reactor. The sulfur dioxide in the flue gas reacts with the activated baking soda in the reactor and is removed. After desulfurization, the flue gas enters the bag filter, and the solid products generated by desulfurization and the soot are efficiently captured together. After desulfurization and dust removal, the purified flue gas (130°C - 190°C) enters the chimney for emission through the induced draft fan.

[0046] During the entire flue gas circulation and emission process, the humidity of the flue gas is stable. Under normal circumstances, the humidity range should be within the interval of 5% ± 1%.

[0047] Optionally, the humidity includes the humidity at the inlet of the desulfurization reactor and the humidity at the chimney emission outlet.

[0048] Measure the humidity at the inlet of the desulfurization reactor and the chimney emission outlet, that is, there are measurement points before the flue gas of the CDQ desulfurization technical transformation project enters the desulfurization reactor and after desulfurization and dust removal and before going to the chimney for emission, to ensure accurate measurement of the humidity of the circulating flue gas.

[0049] Step S200, analyze the internal parameters of the system to determine whether the CDQ boiler system is in a normal operating state.

[0050] In one embodiment, the internal humidity of the system is obtained through the circulating flue gas humidity detection table inside the CDQ system, and the humidity is monitored in real time. In the CDQ system, the humidity range should always be maintained between 4% - 6%. Due to the relatively high pressure of the circulating flue gas in the CDQ system, in the blowdown and emission part of each cycle, the gas is discharged unidirectionally outward, and new flue gas with the same substance content is introduced in a new round of cycle, so the humidity always remains in a stable interval and will not fluctuate greatly. If the humidity abnormally rises above 6%, it indicates that the circulation process of the gas in the pipeline has changed, indicating that some problems may have occurred in the CDQ system.

[0051] In one embodiment, determine whether the humidity of the circulating flue gas is greater than 6%. If it is greater than 6%, attention needs to be paid, and it can be initially suspected that a pipe burst accident has occurred.

[0052] In another embodiment, if the detected humidity of the circulating flue gas is less than 4% - 6%, it indicates that there is no abnormality in the humidity of the circulating flue gas.

[0053] Step S300, if the CDQ boiler system is not in the normal operating state, determine the corresponding preset treatment plan based on the internal parameters of the system.

[0054] In one embodiment, if the humidity is greater than 6%, it is determined that the system is not in a normal operating state, and the corresponding preset treatment plan needs to be determined based on the specific value of the humidity of the circulating flue gas. When the humidity of the circulating flue gas is slightly greater than 6%, it indicates that the system may have an abnormality. At this time, fault troubleshooting can be carried out to discover problems in time and prevent the further expansion of pipe burst leakage points. After determining the fault problem, then judge whether it is necessary to stop the machine to prevent economic losses caused by blind shutdown and ensure the safety of workers; when the humidity of the circulating flue gas is much greater than 6%, it can be determined that the system has a fault. At this time, it is necessary to directly stop the machine and then carry out fault troubleshooting to prevent the escalation of the accident. Stopping the machine immediately also ensures the safety of workers.

[0055] Optionally, step S200 includes:

[0056] Step S210, obtaining the humidity.

[0057] Step S211, determining whether the humidity is greater than a first threshold.

[0058] Step S212: If the humidity is greater than the first threshold, it is determined that the CDQ boiler system is not in the normal operating state.

[0059] In one embodiment, the humidity of the circulating flue gas is obtained. Preferably, the humidity parameters at the air inlet of the desulfurization reactor and the chimney outlet are obtained to determine whether the humidity is greater than 6%. If greater than 6%, it indicates that the humidity is abnormal, and it is determined that the dry coke quenching boiler system is not in a normal operating state.

[0060] In one embodiment, the humidity is obtained by taking the average of the humidity at the air inlet of the desulfurization reactor and the humidity at the chimney outlet, so as to ensure that the humidity value is obtained accurately.

[0061] In another embodiment, the humidity at the air inlet of the desulfurization reactor is compared with the humidity at the chimney outlet, and the higher humidity is taken as the detected humidity, so as to prevent failure or detection error of one of the humidity sensors and ensure that abnormal humidity is not missed.

[0062] Optionally, step S300 includes:

[0063] Step S301, determining whether the humidity is greater than a third threshold, wherein the third threshold is greater than the first threshold.

[0064] Step S302: If the humidity is greater than the third threshold, the CDQ boiler system and the induced draft fan are controlled to be interlocked and shut down.

[0065] Step S303, determining whether the humidity is greater than a second threshold, wherein the second threshold is greater than the first threshold, and the second threshold is less than the third threshold.

[0066] Step S304: If the humidity is greater than the second threshold, an alarm is issued and a fault is checked.

[0067] In one embodiment, the third threshold is 10%. After it is determined that the system is not in normal operation, it is determined whether the humidity is greater than 10%. If the humidity of the circulating flue gas is greater than 10%, and its value is much greater than 6%, it can be determined that a pipe burst accident has occurred in the dry quenching boiler system with a high probability. At this time, the dry quenching boiler system and the induced draft fan are controlled to be interlocked and shut down. At the same time, the pressure and temperature inside the pipeline are reduced through process control to meet the maintenance conditions.

[0068] In one embodiment, when the detected circulating flue gas humidity is greater than 10%, the corresponding display module is controlled to display red, indicating that it is in a shutdown warning state.

[0069] In another embodiment, the second threshold is 7%. After it is determined that the system is not in normal operation, it is determined whether the humidity is greater than 7%. If the circulating flue gas humidity is greater than 7% and its value is slightly greater than 6%, it means that the dry quenching boiler system is abnormal and water may have entered the system. The system will not be shut down temporarily, but an alarm will be issued and troubleshooting will be performed. First, the humidity detection instrument will be calibrated and compared to eliminate the instrument failure, and then the cause will be further analyzed until the failure is eliminated.

[0070] In one embodiment, when the detected circulating flue gas humidity is greater than 7%, the corresponding display module is controlled to display yellow, indicating that it is in an abnormal state.

[0071] Optionally, when the humidity is greater than the second threshold value and lasts for a preset time, it is determined whether the fluctuation of the internal parameter of the system is greater than a preset fluctuation.

[0072] Since the leakage of boiler tube burst always increases from small to large, the changes in the system internal parameters should be analyzed after the circulating flue gas humidity is greater than the second threshold and lasts for a certain period of time.

[0073] In one embodiment, when the humidity of the circulating flue gas is greater than 7% and lasts for a period of time, it is suspected that a tube burst accident has occurred in the boiler. The dry coke quenching operator can confirm the situation by draining water through the low-point drain valve on site, and pay attention to the changes in the internal parameters of the dry coke quenching system. The internal parameters of the dry coke quenching system include hydrogen content, internal pressure, and internal temperature. It is determined whether the hydrogen content exceeds the preset threshold of hydrogen, and whether the fluctuation range of the internal pressure and internal temperature exceeds the fluctuation range under normal conditions.

[0074] Optionally, when the hydrogen content is less than 3%, it is determined that the system is in a normal state; when the hydrogen content is greater than 10%, it is determined that a pipe burst accident has occurred in the system.

[0075] Optionally, the system internal parameters also include the flue gas pressure, flue gas temperature, boiler liquid level and hydrogen content in the pipeline of the dry coke quenching boiler system.

[0076] The flue gas pressure indicates the pressure of each part in the circulation system of the entire CDQ boiler system; the flue gas temperature indicates the temperature of each part in the circulation system of the entire CDQ boiler system.

[0077] In the event of a serious pipe explosion or other production accident, the system's internal parameters will fluctuate abnormally, which will be measured by sensors. The hydrogen content in the circulating gas analyzer will also increase abnormally. In other production accidents, the system's internal parameters will fluctuate abnormally, and other components will not change.

[0078] Therefore, whether a serious pipe burst accident occurs can be judged by obtaining the flue gas pressure, flue gas temperature, boiler liquid level, and hydrogen content in the pipeline.

[0079] Optionally, step S200 further includes:

[0080] When at least one of the following situations occurs, it is determined that the coke dry quenching boiler system is not in the normal operating state:

[0081] The fluctuation range of the flue gas pressure is greater than the first preset range, the fluctuation range of the flue gas temperature is greater than the second preset range, the fluctuation range of the boiler liquid level is greater than the third preset range, and the hydrogen content in the pipeline is greater than the preset hydrogen threshold.

[0082] If the coke dry quenching boiler system is not in the normal operating state, an alarm is given and a fault check is carried out.

[0083] In one embodiment, to prevent the humidity detection device from malfunctioning, by detecting the fluctuation ranges of the flue gas pressure, flue gas temperature, and boiler liquid level, and detecting the hydrogen content in the pipeline to assist in judging whether a pipe burst accident occurs. When the above fluctuation ranges and hydrogen content are abnormal values, it can be determined that the coke dry quenching boiler system is not in the normal operating state. At this time, an alarm is given and a fault check is carried out. It is also possible to control the coke dry quenching boiler and the induced draft fan to interlock and stop.

[0084] In another embodiment, several parameters such as the circulating flue gas humidity, flue gas pressure fluctuation, flue gas temperature fluctuation, boiler liquid level fluctuation, and hydrogen content in the pipeline are combined to judge whether a pipe burst accident occurs. A fourth preset range, a fifth preset range, and a sixth preset range are set. When one of the following situations occurs: the humidity is greater than the third threshold, the fluctuation range of the flue gas pressure is greater than the fourth preset range, the fluctuation range of the flue gas temperature is greater than the fifth preset range, the fluctuation range of the boiler liquid level is greater than the sixth preset range, and the hydrogen content is greater than the second hydrogen threshold, the coke dry quenching boiler and the induced draft fan are controlled to interlock and stop.

[0085] Optionally, the second hydrogen threshold is 10%.

[0086] When one of the following situations occurs: the humidity is greater than the second threshold, the fluctuation range of the flue gas pressure is greater than the first preset range, the fluctuation range of the flue gas temperature is greater than the second preset range, the fluctuation range of the boiler liquid level is greater than the third preset range, and the hydrogen content is greater than the first hydrogen threshold, an alarm is given and a fault check is carried out. To prevent a malfunction of a certain sensor from causing the abnormal information not to be judged in the first time.

[0087] Optionally, the first hydrogen threshold is 3%.

[0088] Optionally, after step S200, it further includes:

[0089] If the coke dry quenching boiler system is in the normal operation state, the internal parameters of the system are re-acquired after a preset interval, and it is determined whether the coke dry quenching boiler system is in the normal operation state.

[0090] After determining that the coke dry quenching boiler system is in the normal operation state, the internal parameters of the system are re-acquired at regular intervals, and it is re-determined whether the coke dry quenching boiler system is in the normal operation state.

[0091] Since tube burst failures often deteriorate continuously from less to more, and the process is continuous, detecting at regular intervals can detect tube burst problems in the first time, providing more preparation time and solutions for maintenance and production organization, reducing the workload of maintenance, and shortening the maintenance time.

[0092] On the other hand, if the flue gas circulation humidity is greater than 6% and less than 10%, it may be necessary to assist in judging whether a tube burst accident has occurred through the fluctuation of the internal parameters of the system. At this time, it is necessary to retrieve the data of the past internal parameters of the system for comparison to calculate the magnitude of the fluctuation.
