Description

Technical Field

[0001] The invention relates to the field of industrial automation, and in particular to a vaporization system. Background Art

[0002] During the smelting process, the converter provides cooling medium for the vaporization cooling flue. During the smelting process, the thermal radiation of the converter flue gas exchanges heat with the flue exhaust pipe, and a steam-water mixture is produced in the vaporization cooling flue pipe. Then, it enters the steam drum through the riser of the flue. The steam-water mixture is separated in the steam drum, and the water continues to circulate through the feed water pump for flue cooling. After the steam reaches a certain pressure, it enters the heat accumulator for storage.

[0003] In the related art, the pressure of the converter vaporization cooling system changes with the converter smelting rhythm. Since the converter smelting rhythm is unstable, the vaporization system exchanges heat with the flue gas during smelting, and the pressure and temperature in the system rise.

[0042] As described in the background technology, during the smelting process, the converter provides a cooling medium for the vaporization cooling flue. During the smelting process, the heat radiation of the converter flue gas exchanges heat with the flue exhaust pipe, and a steam-water mixture is generated in the vaporization cooling flue pipe. Then, it enters the steam drum through the riser of the flue, and the steam-water compounds are separated in the steam drum. The water continues to circulate through the water supply pump for flue cooling, and the steam enters the heat accumulator for storage after reaching a certain pressure. In the related technology, the system pressure of the converter vaporization cooling system changes with the converter smelting rhythm. Since the converter smelting rhythm is unstable, the vaporization system exchanges heat with the flue gas during smelting, and the pressure and temperature in the system rise. When the converter stops smelting, the vaporization system has no heat exchange energy, and the pressure also decreases. In addition, the smelting and shutdown time is very irregular, resulting in a large range of pressure and temperature changes in the vaporization system during operation, which is easy to cause safety accidents.

[0043] The present invention provides a vaporization system, characterized in that the vaporization system includes: a heat accumulator for storing steam; a steam drum for receiving steam from the heat accumulator; a detection device arranged in the steam drum, for obtaining steam information in the steam drum, the steam information including pressure information and / or temperature information in the steam drum; a steam compensation device arranged between the heat accumulator and the steam drum; a main processor electrically connected to the steam compensation device; wherein the steam compensation device includes: a compensation pipeline connecting the heat accumulator and the steam drum, for transporting the steam from the heat accumulator to the steam drum; a control valve group arranged on the compensation pipeline, for controlling whether the compensation pipeline is open; the main processor is used to receive the steam information, and when the steam information does not meet the expected setting, control the compensation pipeline by issuing a control command to the control valve group to adjust the steam information in the steam drum. In this way, the steam from the heat accumulator can be transported to the steam drum through the steam compensation device according to the steam information in the steam drum, thereby adjusting the steam information in the steam drum and further balancing the pressure and / or temperature of the entire vaporization system. Compared with the related art in which the pressure of the converter vaporization cooling system changes with the converter smelting rhythm and is prone to cause safety accidents, the present invention has higher safety.

[0044] In the related art, most converter flues use a close-packed pipe structure with a pipe material of 20g. Since metal materials will creep under the action of pressure and temperature, and the creep amount is proportional to the pressure and temperature fluctuations, the pipe material of the vaporization cooling flue will fatigue prematurely due to the large pressure and temperature fluctuation range of the converter vaporization cooling system, resulting in a reduced service life. In addition, during the smelting process, the vaporization cooling flue leaks and enters the converter molten steel, causing splashing or even explosion accidents.

[0045] In this regard, in an embodiment of the present invention, the vaporization system further includes: a vaporization flue (i.e., a vaporization cooling flue in the related art) disposed above the converter, for receiving moisture from the steam drum according to the steam information in the steam drum; and a first pipe connecting the steam drum and the vaporization flue, for transporting moisture from the steam drum. The vaporization flue can receive moisture from the steam drum through the first pipe according to the steam information in the steam drum, so that the main processor can adjust the moisture in the vaporization flue while adjusting the steam information in the steam drum, thereby further reducing the pressure and / or temperature changes of the vaporization flue and extending the service life of the vaporization flue.

[0046] The technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0047] Figure 1 The structure of the vaporization system according to some embodiments of the present invention is shown. Figure 1 As shown, the vaporization system provided by the present invention comprises:

[0048] accumulator, used to store steam;

[0049] a steam drum for receiving steam from the accumulator;

[0050] A detection device disposed in the steam drum, used for obtaining steam information in the steam drum, wherein the steam information includes pressure information and / or temperature information in the steam drum;

[0051] a steam compensation device disposed between the heat accumulator and the steam drum;

[0052] a main processor electrically connected to the steam compensation device;

[0053] Wherein, the steam compensation device comprises:

[0054] a compensating pipe connecting the heat accumulator and the steam drum, for transporting the steam from the heat accumulator to the steam drum;

[0055] A control valve group arranged on the compensation pipeline, used to control whether the compensation pipeline is open;

[0056] The main processor is used to receive the steam information and, when the steam information does not meet the expected setting, control the compensation pipeline by issuing a control command to the control valve group to adjust the steam information in the steam drum.

[0057] In some embodiments, the detection device disposed in the steam drum may be a pressure sensor and / or a temperature sensor, or other detection devices capable of detecting the pressure and / or temperature in the steam drum. The steam information may be a value directly detected by the detection device, or may be data obtained by further processing the value detected by the detection device.

[0058] In some embodiments, the control valve group may include multiple types of control valves, such as a control valve that controls whether the compensation pipe is open, or a check valve that prevents the steam in the compensation pipe from flowing backward. The control valve group controls whether the compensation pipe is open by switching the valves included therein, and further enables the steam of the heat accumulator to flow to the steam drum through the compensation pipe, thereby balancing the pressure and / or temperature in the steam drum.

[0059] In some embodiments, when the steam information is lower than the expected setting, it indicates that the pressure and / or temperature in the drum is low, and the main processor can open the compensation pipeline by issuing a control command to the control valve group (at this time, the control command instructs the control valve group to open), so that the steam in the heat accumulator can flow to the drum through the compensation pipeline, thereby increasing the pressure and / or temperature in the drum. Correspondingly, when the steam information is higher than the expected setting, it may indicate that the pressure and / or temperature in the drum is high, and the main processor can close the compensation pipeline (at this time, the control command instructs the control valve group to close), so that the steam in the drum is transported to the heat accumulator through the relevant pipeline (such as the steam in the drum described in the related art is transported to the heat accumulator when it reaches a certain value).

[0060] In some embodiments, the main processor can adjust the switch and / or flow of the control valve group according to preset rules, so that the steam information in the steam drum decreases or increases linearly, thereby extending the service life of the equipment.

[0061] In some embodiments, the main processor can not only send control commands to the control valve group based on steam information, but also determine what control commands to send to the control valve group based on signals such as the oxygen gun lifting height, oxygen valve switch signal, oxygen flow, and nitrogen valve switch signal.

[0062] In some embodiments, after receiving the steam information, the main processor can not only determine the control command based on the steam information, but also save the steam information for subsequent viewing and sorting.

[0063] In this way, the steam from the heat accumulator can be transported to the steam drum through the steam compensation device according to the steam information in the steam drum, thereby adjusting the steam information in the steam drum and further balancing the pressure and / or temperature of the entire vaporization system. Compared with the related art in which the pressure of the converter vaporization cooling system changes with the converter smelting rhythm and is prone to cause safety accidents, the present invention has higher safety.

[0064] In some embodiments, the control valve group provided by the embodiment of the present invention includes a regulating control valve, which is used to receive a control command from the main processor and control whether the compensation pipeline is open according to the control command. When the control command indicates to open, the regulating control valve can open the valve, so that the compensation pipeline is opened, and the steam in the heat accumulator can flow to the steam drum. Correspondingly, when the control command indicates to close, the regulating control valve can close the valve, so that the compensation pipeline is closed and steam cannot be transported. The main processor can control whether the compensation pipeline is open through the regulating control valve, and further balance the steam in the heat accumulator and the steam in the steam drum.

[0065] In some embodiments, the control valve group further includes a check valve, which is used to automatically close when the compensation pipeline transports the steam of the drum. The check valve can be a one-way valve that can be automatically closed. When the steam in the compensation pipeline flows in the reverse direction (i.e., from the drum to the heat accumulator), the check valve can automatically close to prevent the steam of the drum from passing through the compensation pipeline to reach the heat accumulator, but the steam of the drum can reach the heat accumulator through other pipelines in the converter vaporization cooling system in the related technology, which will not be described here. The one-way travel of the steam in the compensation pipeline is achieved by the check valve, which facilitates the main processor to perform more targeted management of steam flows in different directions and balance the pressure and / or temperature of the drum.

[0066] In some embodiments, in consideration of the maintenance of the vaporization system and troubleshooting of the control valve group fault, the control valve group further includes a manual stop valve for repairing the vaporization system fault. The manual stop valve is not controlled by the control command of the main processor. The manual stop valve can remain in a normally open state during the operation of the vaporization system provided by the embodiment of the present invention. When the vaporization system is being repaired or troubleshooting, the manual stop valve can be closed manually, thereby closing the entire compensation pipeline for easy maintenance.

[0067] In some embodiments, Figure 2 1 shows a cross-sectional view of a steam compensation device in a steam drum according to some embodiments of the present invention, as shown in FIG. Figure 2 As shown, the steam compensation device provided in the embodiment of the present invention also includes:

[0068] a distribution pipe disposed between the compensation pipe and the steam drum, for accumulating steam from the compensation pipe;

[0069] a nozzle inserted into the steam drum and used for spraying steam from the compensation pipe into the steam drum;

[0070] A sleeve connecting the dispensing tube to the nozzle.

[0071] In some embodiments, the nozzle is made of 1Cr18Ni9Ti. The distribution pipe can wrap the steam drum and connect with the compensation channel outside the steam drum to realize the steam channel and steam accumulation function. The sleeve is used to connect the distribution pipe and the nozzle.

[0072] In some embodiments, the nozzle comprises:

[0073] an expansion section, for receiving steam from the compensation pipe;

[0074] A contraction speed-up section, used to increase the speed of the steam passing through the expansion section;

[0075] The injection section is used to reduce the speed of the steam passing through the contraction and speed-up section, and spray the steam passing through the contraction and speed-up section into the steam drum.

[0076] In some embodiments, the expansion section can ensure that the steam enters the nozzle evenly, the contraction and acceleration section is used to increase the steam flow velocity entering the nozzle, and the injection section is used to reduce the steam rate, steam injection range and uniform injection into the steam drum, so as to fully fill every space in the steam drum and allow the water at the bottom of the steam drum to fully absorb the steam heat and increase the temperature.

[0077] In some embodiments, the vaporization system further comprises:

[0078] The converter is used to generate converter flue gas during the production and smelting process.

[0079] The camera disposed above the converter is used to record the image of the converter and send the image of the converter to the main processor. In some embodiments, the vaporization system also includes a converter that generates converter flue gas, and the converter flue gas can be used to generate steam transported to the steam drum and / or the regenerator. The camera disposed above the converter can capture and record the image of the converter, for example, the image content of the converter may include the amount of smoke from the converter, etc. The image of the converter is sent to the main processor to facilitate unified calculation and processing by the main processor.

[0080] In some embodiments, the main processor is further used to determine the operating status of the converter based on the screen of the converter, and determine the expected settings based on the operating status of the converter.

[0081] In some embodiments, the operating status of the converter may include the converter iron charging period, the early stage of blowing, the middle stage of blowing, the late stage of blowing, the slag splashing period and the non-smelting period.

[0082] In some embodiments, the main processor can find out the changing relationship between the converter iron adding period, early blowing period, middle blowing period, late blowing period, slag splashing period and non-smelting period and the pressure and temperature in the drum based on the recorded steam information, images of the converter at various periods, oxygen lance lifting height, oxygen valve switch signal, oxygen flow rate, and nitrogen valve switch signal through an algorithm, and obtain the changing relationship between the length of the non-smelting period and the pressure and temperature of the drum, so as to determine the expected settings based on the steam information of the drum during the trial period.

[0083] In some embodiments, the expected setting is the ideal value of the steam information in the current production cycle and / or the ideal value of the steam information in the first production cycle, the first production cycle is the next production cycle of the current production cycle, and the production smelting process includes N production cycles.

[0084] In some embodiments, the N production cycles may be the converter iron charging period, the early stage of blowing, the middle stage of blowing, the late stage of blowing, the slag splashing period and the non-smelting period mentioned above. The expected setting may not only characterize the steam information in the drum in the current production cycle, but also characterize the ideal value of the steam information in the drum in the next production cycle. Based on the predicted expected setting, the steam information in the drum may be adjusted in advance to ensure that the pressure in the drum decreases or increases linearly, thereby avoiding the equipment being affected by pressure and temperature fluctuations and resulting in a reduction in life.

[0085] In some embodiments, the vaporization system further includes: a vaporization flue disposed above the converter, for receiving moisture from the steam drum according to the steam information in the steam drum; and a first pipe connecting the steam drum and the vaporization flue, for transporting moisture from the steam drum. A feed water pump may also be provided on the first pipe to transport the water decomposed by the steam drum to the vaporization flue. Receiving moisture from the steam drum through the first pipe and the feed water pump facilitates the main processor to adjust the moisture in the vaporization flue while adjusting the steam information in the steam drum, thereby further reducing the pressure and / or temperature changes of the vaporization flue and extending the service life of the vaporization flue.

[0086] In order to better understand the steam compensation device provided in the embodiment of the present invention, an example is given. In the embodiment of the present invention, the vaporization system includes the following modules:

[0087] (1) Steam drum pressure compensation device: By adding a branch line from the steam drum to the heat accumulator pipeline, the steam from the heat accumulator is returned to the pressure compensation device in the steam drum. Under the control of the branch pipeline valve group, the steam in the heat accumulator passes through the manifold of the pressure compensation device, and then the high-temperature and high-pressure steam in the heat accumulator is compensated to the steam drum through the nozzle.

[0088] (2) Image recognition module: Through the camera and image processing system, each process during the converter smelting and the non-smelting period are monitored in real time.

[0089] (3) Sensor module: including pressure sensor, temperature sensor, switch quantity sensor, flow metering sensor, used to detect drum pressure, converter blowing, excess oxygen content and converter slag splashing process.

[0090] (4) Data analysis and control module: Combined with sensor data and image recognition results, the preset algorithm analysis and self-learning model are used to analyze the changes in pressure and temperature in the converter drum at each stage of the converter. Based on the analysis results and the self-learning model mechanism, the switch signal is provided to the control valve group of the drum replenishment device to ensure pre-control and precise control of the drum pressure and temperature compensation.

[0091] The image recognition module works in coordination with the sensor module: the image recognition module analyzes the images during the converter smelting period and the non-smelting period, and is linked with the oxygen lance lifting height, oxygen valve switch signal, oxygen flow rate, and nitrogen valve switch signal. The algorithm finds out the changing relationship between the converter iron adding period, early blowing period, middle blowing period, late blowing period, slag splashing period, and non-smelting period and the pressure and temperature in the drum. The image recognition and sensor modules can work together to complete the changing relationship between the length of the non-smelting period and the pressure and temperature of the drum, and provide the data module with actual monitoring data of on-site operation.

[0092] Data analysis module: collects image and sensor data, and uses built-in algorithms to analyze the changing trends between the pressure and temperature in the drum during the converter iron addition period, early blowing period, mid-blowing period, late blowing period, slag splashing period, and non-smelting period. When the system predicts or reaches the drum pressure limit, the pressure compensation device control valve group is opened and closed.

[0093] like Figure 3 As shown, the compensation pipe of the steam compensation device is installed on the steam pipe from the steam drum (9) to the heat accumulator. The concept of the steam compensation device can refer to Figure 4 In order to ensure that the accumulator steam can be correctly diverted to the drum, the branch pipeline must be installed behind the control valve group (10) of the drum delivery pipeline. Manual stop valves (1), (3) (5) and check valves (4) and (6) are provided on the pressure compensation device pipeline. The manual stop valve is used in case of valve group failure or drum maintenance. The check valve is used to prevent the backflow of the drum (9) when the pressure in the drum does not reach the delivery pressure to the accumulator (at the same time, the accumulator pressure must be lower than the drum pressure). The control valve (2) is combined with the corresponding module to control the amount of steam entering the drum and adjust the pressure and temperature in the drum.

[0094] The installation front view of the steam compensation device (7) in the steam drum can be referred to Figure 5 , the inner view can refer to Figure 6 The specific installation structure diagram in the steam drum can be referred to Figure 2 , comprising a nozzle (11), a sleeve (12), and a distribution pipe (13), wherein the nozzle (11) comprises an expansion section, a contraction speed-up section, and an injection section, wherein the expansion section ensures that the steam enters the nozzle evenly, the contraction speed-up section is used to increase the steam flow velocity entering the nozzle, and the injection section is used to reduce the steam velocity, the steam injection range, and uniform injection into the steam drum, so as to fully fill every space in the steam drum and allow the water at the bottom of the steam drum to fully absorb the heat of the steam and increase the temperature, and the material of the nozzle is 1Cr18Ni9Ti; the sleeve (12) is used to connect the distribution pipe (13) and the nozzle (11); the distribution pipe (13) is connected to a branch pipeline outside the steam drum, and acts as a steam channel and steam storage.

[0095] In an embodiment of the present invention, the operation of the vaporization system includes the following steps:

[0096] Monitoring and judgment;

[0097] Image recognition and sensor data acquisition;

[0098] Data analysis and prediction of drum pressure trend;

[0099] Start-up control of the drum pressure replenishment device.

[0100] The control logic of the main processor can be understood as follows: Under normal conditions, the system continuously monitors whether the converter enters smelting, oxygen lance height, oxygen valve switch, oxygen lance oxygen blowing volume, nitrogen valve switch, and drum pressure and temperature data, and records the data. Under abnormal conditions, once it is detected and predicted that the drum pressure is lower or higher than the set value, the system quickly analyzes and adjusts the control valve of the pressure compensation device according to the preset rules to ensure that the pressure in the drum decreases or increases linearly, avoiding the reduction of the life of the flue gas pipe due to the pressure and temperature fluctuations.

[0101] The vaporization system provided by the embodiment of the present invention realizes intelligent pressure and temperature compensation control through image recognition and sensor data fusion, which is convenient for early prediction and protection of pressure changes in the vaporization cooling flue. It also includes a real-time data analysis and feedback mechanism, real-time judgment and control based on big data and self-learning model analysis, and improves the response speed and accuracy of the system.

[0102] In addition, the vaporization system provided by the embodiment of the present invention also has the following advantages:

[0103] (1) Reduce investment costs: The original oxygen lance control sensor and the drum pressure and temperature sensor data are incorporated into the device's data analysis system to reduce investment costs.

[0104] (2) Compensate the pressure and temperature of the vaporization system: Based on the set value and image recognition and sensor fusion technology, the pressure and temperature of the vaporization system are compensated by controlling the regulating valve group of the replenishment device, thereby reducing the impact of the pressure and temperature fluctuations during the converter smelting process on the life of the flue metal materials and reducing the probability of flue leakage.

[0105] (3) Full integration of pressure and temperature: By rationally designing the nozzle of the replenishment device, the filling pressure in the drum and the heat absorption effect of water and steam in the drum are improved, thereby reducing the cost of steam use.

[0106] (4) Predict the relationship between drum pressure and converter smelting process: Through image recognition and data analysis, the relationship between the converter non-smelting and smelting period and the drum pressure and temperature changes can be self-learned through algorithms, which can better control the pressure and temperature changes and provide a basis for the adjustment of the pressure compensation device;

[0107] (5) Improving the service life of the converter flue: Using an intelligent braking system to reduce the fluctuation of pressure and temperature of the converter vaporization cooling flue system, thereby improving the service life of the flue pipe;

[0108] (6) Automation and intelligence: The system can operate autonomously, reducing human intervention and lowering maintenance costs.

However, those skilled in the art should understand that various technical means can be used to form layers, regions, etc. of desired shapes. In addition, in order to form the same structure, those skilled in the art can also design methods that are not completely the same as the methods described above.
