Description

Technical Field

[0001] The present invention relates to the technical field of atomizers, and particularly relates to a remote warning control system and method for an atomizer. Background Art

[0002] In industrial production, the flue gas generated often contains a lot of acidic substances such as sulfur dioxide and hydrogen chloride. In industries such as waste incineration, thermal power generation, steel production, and coke production, flue gas desulfurization equipment is required. The commonly used process for flue gas desulfurization is semi-dry flue gas desulfurization. After the calcium hydroxide solution is atomized, it reacts fully with the acidic substances in the flue gas to achieve the effect of removing most of the acidic substances. Among them, the most core component of the semi-dry method is the rotary atomizer located at the top of the reaction tower. The stable operation of the rotary atomizer is related to whether the flue gas emission index can meet the environmental protection standards. At the same time, whether it can provide a pre-judgment before problems occur, and whether it can timely judge the cause of the failure and resume operation after a failure shutdown has become an important factor for stable operation in the factory. At present, the atomizer system includes an automatic control system for the equipment body, and the in-factory control is carried out in the central control room. The atomizer manufacturer or the engineering commissioning and maintenance personnel cannot see the equipment operation data.

[0070] The following will elaborate on the embodiments of the present invention. These embodiments are implemented on the premise of the technical solutions of the present invention, and detailed implementation methods and specific operation processes are given. However, the protection scope of the present invention is not limited to the following embodiments.

[0071] In the description of the specification of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0072] As shown Figure 1 in the figure is a schematic diagram of a remote warning control system for an atomizer according to an embodiment of the present invention.

[0073] Please refer to Figure 1 , the remote warning control system for the atomizer in this embodiment includes: a remote operation parameter acquisition device 1 and a warning device 2. Among them, the remote operation parameter acquisition device 1 acquires the parameters during the operation of the atomizer system; the warning device 2 is connected to the remote operation parameter acquisition device 1, receives the parameters acquired by the remote operation parameter acquisition device 1, and judges whether it exceeds the preset warning range or is greater than the preset warning value or is less than the preset warning value. If so, a warning signal is issued. The remote operation parameter acquisition device includes any one or more of: a temperature acquisition device, a pressure acquisition device, a flow rate acquisition device, a vibration acquisition component, and a flue gas composition analyzer; among them: the temperature acquisition device acquires any one or more of the motor temperature, bearing temperature, and cooling water temperature of the atomizer system; the pressure acquisition device acquires any one or more of the water pressure, lubricating oil pressure, and compressed air pressure of the atomizer system; the flow rate acquisition device acquires the lubricating oil flow rate and / or compressed air flow rate of the atomizer system; the vibration acquisition component acquires the vibration value of the atomizer system; the flue gas composition analyzer analyzes the flue gas composition.

[0074] In different embodiments, the requirements of the atomizer system for different parameters are different. For some parameters, fluctuations within a certain range are allowed. In this case, a preset warning value range is set in the warning device, and a warning is issued when the preset warning range is exceeded. For some parameters, a certain value cannot be exceeded. In this case, a warning preset value is set in the warning device, and a warning is issued when it is greater than the warning preset value. For some parameters, a certain value cannot be lower than. In this case, a warning preset value is set in the warning device, and a warning is issued when it is less than the warning preset value.

[0075] The atomizer will have different problems under different working conditions in different projects. The atomizer manufacturer and professional commissioning personnel for flue gas projects can easily predict possible problems. Since the data in the factory cannot be seen remotely, often before some signs of problems appear, not everyone in the factory can judge in time. And professional personnel can know the problems in advance based on the operation data, or judge whether it is time for equipment maintenance. Therefore, the preset warning range set according to the experience of professional personnel in the warning device can prompt in advance that maintenance is required on site before a failure occurs in the atomizer system, reducing the incidence of failure shutdowns.

[0076] In a preferred embodiment, the remote warning control system for the atomizer further includes: a first operation control device 3, and the first operation control device 3 is directly or indirectly electrically connected to the warning device 2. Please refer to Figure 2When the warning device emits a warning signal, the second operation control device is used to receive the warning signal and control the atomizer system to stop running. When the staff fails to detect the warning signal, the atomizer system can be automatically controlled to stop running to prevent damage to the atomizer caused by the working conditions.

[0077] In different embodiments, the first operation control device may not be included. When the staff receives an alarm signal, they can stop it manually; or, it can also be repaired in a timely manner without stopping the operation, and there is no need to stop the operation after the repair is completed.

[0078] In a preferred embodiment, the remote warning control system for the atomizer further includes: an alarm device 4. The alarm device 4 is connected to the remote operation parameter acquisition device 1, receives the parameters acquired by the remote operation parameter acquisition device, and determines whether they exceed the preset alarm range or are greater than or less than the preset alarm value. If so, it emits an alarm signal; during the same operation process, the alarm signal comes after the warning signal, and the alarm signal is more urgent than the warning signal. The warning signal is triggered in advance. When the staff fails to detect the warning or the problem is not solved, and the parameters exceed the preset alarm range during the continuous operation of the atomizer system, the alarm signal is triggered to remind the staff again that emergency maintenance is required on site.

[0079] In a preferred embodiment, the remote warning control system for the atomizer further includes: a second operation control device 5. The second operation control device 5 is directly or indirectly electrically connected to the alarm device 4. Please refer to Figure 4 When the alarm device 4 emits an alarm signal, the second operation control device receives the alarm signal and controls the atomizer system to stop running.

[0080] In different embodiments, the second operation control device may not be included. When the staff receives an alarm signal, they can stop it manually; or, it can also be repaired in a timely manner without stopping the operation, and there is no need to stop the operation after the repair is completed.

[0081] In a preferred embodiment, the atomizer system includes: an atomizer body and a mechanical cabinet. The mechanical cabinet includes: a cooling water pump, a lubricating oil pump, and a compressed air solenoid valve. The temperature acquisition device is used to acquire any one or more of the motor temperature, bearing temperature, and cooling water temperature of the atomizer system. The pressure acquisition device acquires any one or more of the water pressure, lubricating oil pressure, and compressed air pressure of the atomizer. The flow rate acquisition device acquires the lubricating oil flow rate and / or compressed air flow rate of the atomizer system. The vibration acquisition device acquires the vibration value of the atomizer system.

[0082] In a preferred embodiment, the remote warning control system for the atomizer further includes: a detection component. Before the atomizer is started, the detection component detects whether the parameters of the atomizer meet the preset requirements.

[0083] In a preferred embodiment, the atomizer system further includes: a third operation control device, which is directly or indirectly electrically connected to the detection component; when the parameters of the atomizer detected by the detection component meet the preset requirements, the operation control unit controls the atomizer to start.

[0084] In different embodiments, the third operation control device may not be included, and it may also be manually started when the parameters meet the requirements.

[0085] In different embodiments, when any two of the above-mentioned first operation control device, second operation control device, and third operation control device are included, or all three are included at the same time, any two devices can use the same one, or all three devices can use the same one. For example, when the first operation control device and the second operation control device are included at the same time, both can use the same operation control device, which is connected to the warning device and the alarm device at the same time, and can receive both the warning signal and the alarm signal. When the first operation control device and the third operation control device are included at the same time, or when the second operation control device and the third operation control device are included at the same time, the same operation control device can also be used, which will not be elaborated here. When all three operation control devices are included at the same time, the same operation control device can also be used, which is connected to the warning device, the alarm device, and the detection component at the same time; in addition, when all three operation control devices are included at the same time, any two of them can also use the same operation control device.

[0086] In a preferred embodiment, the atomizer remote warning control system further includes: a wireless communication unit, which is respectively connected to the remote operation parameter acquisition device and the warning device. The wireless communication unit receives the parameters of the atomizer during operation collected by the remote operation parameter acquisition device and the warning signal of the warning device and transmits them to the server side, and also receives the control signal of the server side to control the warning device.

[0087] In one embodiment, the wireless communication unit can use a wireless gateway. After inserting a mobile phone data card into the wireless gateway, the operation data of the atomizer can be uploaded to the server through the mobile phone network traffic. Engineers of the atomizer manufacturer or equipment debugging personnel can also upload the program in the PLC to a personal computer through the wireless gateway. After modifying or maintaining the program, it can be downloaded to the PLC through the wireless gateway to control its internal operation, realizing off-site and wireless remote maintenance of the equipment at any time and anywhere. At the same time, because the operation data and history of the atomizer can be recorded in the server, it can be more quickly clear about the problem and guide the handling of the problem when remotely assisting the operators in the factory to handle problems.

[0088] In a preferred embodiment, the remote operating parameter acquisition device includes: at least one tower body temperature sensor, at least one tower wall temperature sensor, a flue gas temperature sensor, a flow sensor, and a flue gas composition analyzer. The tower body temperature sensor is arranged in the straight cylinder section of the reaction tower of the atomizer system to collect the temperature of the straight cylinder section of the reaction tower. The tower wall temperature sensor is arranged on the tower wall of the reaction tower to collect the temperature of the tower wall of the reaction tower. The flue gas temperature sensor is arranged at the outlet flue of the reaction tower to collect the temperature of the outlet flue of the reaction tower. The flow sensor is arranged on the inlet slurry pipeline of the reaction tower to collect the slurry flow rate of the inlet slurry pipeline of the reaction tower. The flow sensor is also arranged at the outlet flue of the reaction tower to collect the flue gas flow rate of the outlet flue of the reaction tower. The flue gas composition analyzer is arranged at the outlet flue of the reaction tower to analyze the flue gas composition of the outlet flue of the reaction tower.

[0089] In one embodiment, there may be three tower body temperature sensors, which are respectively arranged at three different heights in the straight cylinder section of the reaction tower.

[0090] In one embodiment, there may be three tower wall temperature sensors, which are respectively arranged on the middle tower wall and the lower tower wall of the reaction tower.

[0091] In a preferred embodiment, it further includes: a slurry flow regulating valve, which is arranged at the outlet flue of the reaction tower and can regulate the slurry flow rate of the outlet flue of the reaction tower.

[0092] In one embodiment, the regulation of the slurry flow regulating valve can be carried out according to the temperature of the outlet flue collected by the flue gas temperature sensor. For example, it can be: when the temperature of the outlet flue is lower than the set value, the opening of the regulating valve is reduced by 10% each time; when the temperature of the outlet flue is higher than the set value, the opening of the regulating valve is increased by 10% each time. After 5 minutes, it is judged whether the set temperature is reached by comparison and whether to continue the regulation. If the flue gas parameters SOx and HCL at the outlet of the reaction tower do not meet the standards at this time, the slurry spraying amount is continuously increased until the temperature of the outlet flue reaches the lowest allowable limit.

[0093] In a preferred embodiment, it further includes: a frequency converter, which regulates the rotation speed of the atomizer system.

[0094] As Figure 5 shown is the flowchart of the atomizer remote early warning control method according to an embodiment of the present invention.

[0095] Please refer to Figure 5 , the atomizer remote early warning control method of this embodiment includes:

[0096] S91: Collect the parameters during the operation of the atomizer system;

[0097] S92: Determine whether the parameters collected in S91 exceed the preset warning range. If so, send a warning signal.

[0098] In a preferred embodiment, please refer to Figure 6 , after S92, it further includes:

[0099] S93: Determine whether the parameters collected in S91 exceed the preset alarm range. If so, send an alarm signal.

[0100] In a preferred embodiment, S91 includes: the flue gas temperature, the tower wall temperature of the straight cylinder section of the reaction tower, and the temperature of the outlet flue.

[0101] After S91, it further includes:

[0102] S141: According to the change trend of the difference between the tower wall temperature and the flue gas temperature of the straight cylinder section of the tower body, determine whether there is a wall hanging situation. If there is a wall hanging situation, limit or alarm the slurry flow rate of the inlet slurry pipeline of the reaction tower; and / or,

[0103] S142: Adjust the slurry flow rate of the outlet flue according to the temperature of the outlet flue. When the temperature of the outlet flue is lower than the preset value, reduce the slurry flow rate of the outlet flue. When the temperature of the outlet flue is higher than the preset value, increase the slurry flow rate of the smoking flue;

[0104] S141 and S142 have no sequence order. It can be that S142 is after S141, or S141 is after S142, or both can be carried out simultaneously.

[0105] In an embodiment, in S141, according to the change trend of the difference between the tower wall temperature and the flue gas temperature of the straight cylinder section of the tower body, determining whether there is a wall hanging situation is specifically as follows: When the tower wall temperature is more than 30°C lower than the flue gas temperature of the straight cylinder section of the tower body, it is determined that there is a tendency of wall hanging. When it lasts for more than 5 minutes, it is determined as wall hanging, and gradually reduce the regulated slurry inlet flow rate by 5% each time. When the tower wall temperature is more than 50°C lower than the flue gas temperature of the straight cylinder section of the tower body and lasts for more than 5 minutes, it is determined that wall hanging has occurred, and immediately adjust the slurry inlet flow rate, reducing it by 10% each time. When making each adjustment, it is best to last for five minutes and then determine whether further adjustment is needed.

[0106] In one embodiment, two tower wall temperatures can be collected: the first tower wall temperature and the second tower wall temperature; at the same time, the flue gas temperatures of two straight sections of the tower body are collected: the flue gas temperature of the first straight section of the tower body and the flue gas temperature of the second straight section of the tower body. The first tower wall temperature and the flue gas temperature of the first straight section of the tower body are the temperatures at the first height of the reaction tower, and the second tower wall temperature and the flue gas temperature of the second straight section of the tower body are the temperatures at the second height of the reaction tower. The first height is different from the second height. The temperature difference at different heights is used to judge whether there is wall hanging, and the judgment is more accurate. Specifically, when the first tower wall temperature is more than 30°C lower than the flue gas temperature of the first straight section of the tower body or the second tower wall temperature is more than 30°C lower than the flue gas temperature of the second straight section of the tower body, it is judged that there is a tendency of wall hanging. When it lasts for more than 5 minutes, it is judged as wall hanging, and the slurry feeding flow rate is gradually reduced by 5% each time. When the first tower wall temperature is more than 50°C lower than the flue gas temperature of the first straight section of the tower body or the second tower wall temperature is more than 50°C lower than the flue gas temperature of the second straight section of the tower body, and it lasts for more than 5 minutes, it is judged that wall hanging has occurred, and the slurry feeding flow rate is immediately adjusted, reducing by 10% each time. When the first tower wall temperature is more than 50°C lower than the flue gas temperature of the first straight section of the tower body and the second tower wall temperature is more than 50°C lower than the flue gas temperature of the second straight section of the tower body occur simultaneously, it is judged as serious wall hanging, and the slurry feeding flow rate is immediately adjusted, reducing by 10% each time. When making each adjustment, it is best to last for five minutes and then judge whether further adjustment is needed.

[0107] In a preferred embodiment, S91 further includes: collecting the flue gas flow rate of the outlet flue of the reaction tower and analyzing the flue gas composition of the outlet flue; further, according to the diameter of the reaction tower, the flue gas flow rate of the outlet flue of the reaction tower and the flue gas composition of the outlet flue, the rotation speed of the atomizer system is adjusted so that the slurry flowing out of the inlet slurry pipeline of the reaction tower does not have overspray, and the energy consumption of the atomizer system is not higher than a preset value.

[0108] Specifically, the rotation speed of the atomizer can be adjusted within the range of 0 - 12,000 revolutions per minute (rpm). The commonly used range of the atomizer's rotation speed is 8,000 - 12,000 rpm. However, for different reaction tower diameters, different flue gas volumes, and different flue gas compositions, the most suitable rotation speeds required are different. Even for the same equipment size, different rotation speeds are needed due to different flue gas compositions. At the optimal rotation speed, the best atomization effect and reaction effect can be achieved, the dosage of the reactant is most reasonable without overspray, and at the same time, the rotation speed is not too high to cause waste of system energy consumption. The specific operation method is as follows: When the atomizer is running, the adjustment range is set between 8,000 - 12,000 rpm. After operation, the atomizer system conducts a running stability test every 500 revolutions from 8,000 - 12,000 rpm, either manually or automatically by the system. When the difference in the temperature sensor H at the outlet of the reaction tower is less than 10 degrees after running at two adjacent rotation speeds for 5 minutes, it is determined that the gain brought by the rotation speed has reached a stable value, and the rotation speed will not be increased to avoid energy waste caused by blindly increasing the rotation speed. During operation, the PLC program will adjust from 8,000 - 12,000 rpm to find a reasonable rotation speed, and comprehensively judge the reasonable value of the rotation speed based on the change in the vibration value within 7 - 14 days. When the vibration curve of the atomizer grows rapidly during operation (the vibration value increases by more than 50% in 24 hours), or the vibration value exceeds the alarm setting value twice within 7 days, it is determined that the slurry scales quickly at this rotation speed, and then the rotation speed is reduced by 500 revolutions, and the running stability is recorded for 7 days.

[0109] In another preferred embodiment, it further includes: setting or correcting the operating parameters of the target atomizer system according to the operating parameters of other atomizers, which specifically includes:

[0110] S161: Regional analysis;

[0111] Analyze and compare the operating conditions of atomizers with the same model as the target atomizer in the adjacent area. Compare and obtain the atomizer with the best operating conditions, and use the operating parameters of the atomizer with the best operating conditions as the initial operating parameters of this atomizer; the adjacent area is the area where the distance from the target atomizer does not exceed the preset range.

[0112] Specifically: Analyze and compare the operating information of atomizers with the same model in similar regions in China. The garbage compositions in similar regions are approximate, and the flue gas compositions and parameters are approximate. Through the GPS positioning function of the remote module, the location information of all atomizers is fed back to the server. The server takes the atomizers with adjacent locations (automatically tracked), or approximate climate conditions (manually input), and approximate garbage compositions (garbage composition is manually input) as comparison references. When the approximate atomizer operates stably, the equipment operation parameters during stable operation are used as the operation values for the initial commissioning items (such as the opening of the slurry regulating valve, slurry concentration, atomizer rotation speed, etc.), which can avoid repeated tests during commissioning.

[0113] S162: Fault analysis;

[0114] Compare the failure frequencies and time of multiple atomizers with the same target atomizer model to obtain the high failure points of the atomizer, so as to check whether there are high failure points in the target atomizer; The judgment method for the high failure points of the atomizer is: within a preset time, the alarm frequency of this failure exceeds the preset range.

[0115] The following is an example of a failure: within 7 days or 14 days, the alarm frequency of a certain parameter is relatively high. For example, if the compressed air alarms, it reflects that the stability of the plant's gas source is poor, prompting the customer to improve the operating environment. The alarms of lubricating oil parameters and cooling water parameters can be inferred in the same way, indicating that this process link needs to be checked. When the analog parameters of the equipment (temperature, vibration, current, etc.) increase too fast within a short period of time, such as increasing by 30%-50% within a day (which can be set), it can be predicted as abnormal, prompting the customer to perform maintenance. It is also possible to analyze the failure points that occur in the equipment among all atomizers. For example, through one-year data analysis, judge the service life of the equipment. It is preset that the vibration of the atomizer should not exceed the design point within one year. If the vibration value of the equipment exceeds the first-level alarm point within one year, it means that the design stability of the atomizing disk of the atomizer needs to be improved, and the material or design needs to be improved, and suggestions are provided for the design of the equipment in reverse.

[0116] S163: Operating parameter correction;

[0117] Analyze and compare the operating parameters of the atomizers with the same target atomizer model in the adjacent area one by one. For a certain operating parameter, the operating parameter of the atomizer that does not experience shutdown or alarm within the preset time is the stable value, and the stable value is used to correct the operating parameter of the target atomizer.

[0118] The following is a specific example: Based on the data during the stable period of the recording device, the stable data is used as the reference value during the control and adjustment of on-site equipment. At the same time, the fault value during the operation of the recording device is recorded and used as the warning value for the operation of on-site equipment. If the equipment does not experience shutdown or alarm within 7 - 14 days, it is corrected as the stable value to the server database. This operation value (slurry flow regulating valve, atomizer inverter speed, slurry concentration) is sent to the on-site PLC as the stable operation value of the equipment and serves as the basic operation value. The automatic operation adjustment of the later program will be adjusted near the reference operation value, and the adjustment range can be set, which avoids the misoperation of operators and also avoids the lag and instability of the automatic adjustment of on-site equipment. The stable recorded values at different loads (flue gas flow 50% - 100%) are used as the operation value reference for different loads and uploaded to the server. After the process equipment is put into use again, the reference operation value will be used as the preset value for operation. During the commissioning stage or the initial operation stage of similar projects (adjacent regions, similar waste components, etc.), the stable operation values of similar projects in the server will be used as the initial preset values (flow regulating valve, atomizer inverter speed, slurry concentration). After this project operates stably and there is no shutdown or alarm within 7 - 14 days, the stable value of this project will be updated as the operation reference value of this project. If the waste components fluctuate, the waste components of this project are manually input, and the stable recorded values in the database will be updated by the on-site operation values.

[0119] S164: Reverse detection and analysis of slurry quality;

[0120] Compare the target atomizer with an atomizer of the same model and the same flue gas parameters, and judge whether the difference in the flue gas treatment effect between the two exceeds the preset range when the slurry flow rates are the same. If it exceeds the preset range and the effect of the target atomizer is poor, it is necessary to increase the concentration of the preset active ingredient in the slurry of the target atomizer. When there is still a difference when the concentration reaches the preset value, it indicates that the preset active ingredient in the slurry is poor, and it is prompted to check the preset active ingredient to improve the operation effect and reduce energy consumption.

[0121] The following is a specific illustration: For example, if there is a large difference in the removal effects of Sox and Hcl in flue gas treatment, it is necessary to increase the concentration of Ca(OH)2 in the slurry of the target atomizer. When there is still a difference when the concentration reaches 13%, it indicates that the active ingredient of Ca(OH)2 in the slurry is poor, and it is prompted to check the active ingredient of Ca(OH)2.
