Description

Technical Field

[0001] The invention relates to the technical field of water jacket furnaces, and in particular to an intelligent measurement and control device, system and method for a water jacket heating furnace. Background Art

[0002] At present, many production blocks in the oil field have super-heavy oil, extra-heavy oil and ordinary heavy oil. After the crude oil is mined and brought into the station, it is difficult to transport it out due to its high viscosity and poor fluidity. At the same time, it causes high back pressure in the oil well, which seriously affects the production capacity of the oil well. In view of this situation, water jacket furnace heating is often used to heat the crude oil to a higher temperature (90℃) to reduce the viscosity of the crude oil and realize the transportation of crude oil.

[0003] During the daily production and operation of the water-jacketed furnace, the water in the water jacket will be consumed and often needs to be replenished. However, the operating staff cannot always observe the water addition on site, which may easily lead to excessive water addition and waste of water resources.

[0004] Therefore, there is a need for an intelligent measurement and control device, system and method for a water jacket heating furnace that can accurately replenish water, improve production efficiency and reduce labor costs. Summary of the invention

[0005] One of the purposes of the present invention is to provide an intelligent measurement and control device for a water jacket heating furnace, which can achieve accurate water replenishment.

[0006] In order to solve the above technical problems, this application provides the following technical solutions:

[0007] The intelligent measurement and control device of the water jacket heating furnace comprises a water jacket furnace body, and a water supply tank arranged on the top of the water jacket furnace body, and also comprises a water supply pipe, a controller, a normally closed solenoid valve and a water level control valve located in the water supply tank;

[0008] The water level control valve comprises a water level control valve body, a connecting rod and a floating ball; the floating ball is connected to the water level control valve body through the connecting rod; water inlet holes are opened on the side wall and the top of the water tank, and the water supply pipe passes through the water inlet holes on the side wall of the water tank and is connected to the water inlet end of the water level control valve body;

[0009] The normally closed solenoid valve is installed on the water inlet hole on the top of the water tank, the water supply pipe is also connected to the normally closed solenoid valve, and the normally closed solenoid valve is electrically connected to the controller.

[0010] The basic scheme principles and beneficial effects are as follows:

[0011] In this solution, a water level control valve is set in the water tank, and the conversion of the open and closed states of the water level control valve body mainly relies on the float to sense the change of the liquid level. During the production process of the water jacket furnace, if the water in the water jacket furnace body is consumed, the liquid level in the water tank will change. The float set in the water tank will move downward with the change of the liquid level. When the liquid level drops, the float will drop accordingly. When the float drops, the valve of the water level control valve body opens, and water flows through the water supply pipe, flows out of the water level control valve body, and enters the water tank to replenish water for the water jacket furnace body. When the liquid level rises, the float will move upward accordingly. When the float rises to a certain height, the valve of the water level control valve body is closed, and the water discharge into the water jacket furnace body is automatically stopped.

[0012] In order to further accurately control the amount of water added and facilitate active intervention in water addition, this solution also installs a normally closed solenoid valve on the water inlet hole at the top of the water tank. In daily use, the normally closed solenoid valve is closed. When the amount of water added needs to be actively controlled or the water level control valve fails, the normally closed solenoid valve can be controlled by the controller to open and add water to the water jacket furnace body. Since the normally closed solenoid valve is located at the top of the water tank, the amount of water added can be higher than the amount of water added by the water level control valve.

[0013] In summary, this solution can automatically complete the water replenishment of the water jacket furnace body and can also accurately control the amount of water added. Compared with manual control, it can reduce labor costs and improve production efficiency.

[0014] Furthermore, it also includes a liquid level sensor disposed in the water jacket furnace body, and the liquid level sensor is electrically connected to the controller;

[0015] The controller is used to obtain liquid level data from the liquid level sensor and determine whether the liquid level is lower than the warning value based on the liquid level data. If it is lower than the warning value, the normally closed solenoid valve is controlled to open.

[0016] By monitoring the liquid level, when the liquid level is lower than the warning value, that is, when the water level control valve does not play its due role, water can be injected into the water jacket furnace body in time to avoid damage to the water jacket furnace.

[0017] Furthermore, it also includes a temperature sensor disposed in the water jacket furnace body, and the temperature sensor is electrically connected to the controller;

[0018] The controller is also used to obtain temperature data from the temperature sensor, determine the current preset liquid level based on the temperature data and the preset liquid level parameters, and determine whether the liquid level is lower than the preset liquid level based on the liquid level data. If it is lower than the preset liquid level, determine whether the liquid level is in a rising state based on the liquid level data within a preset time. If it is not in a rising state, control the normally closed solenoid valve to open.

[0019] In this preferred embodiment, above the liquid level at which the water level control valve automatically adds water, different preset liquid levels can be set for different temperatures. After the water level control valve stops adding water, water continues to be added to the water jacket furnace body. The amount of water added can be controlled in a targeted manner according to the working status of the water jacket furnace body at different temperatures.

[0020] Furthermore, the controller is also used to determine whether the temperature is in a stable state based on the temperature data within the preset time. If it is in a stable state, determine whether the liquid level is in a declining state based on the liquid level data within the preset time. If it is in a declining state, determine whether the decline in the liquid level within the preset time is higher than a threshold. If it is higher than the threshold, generate an alarm message.

[0021] The temperature is stable, indicating that there is no abnormal temperature fluctuation. However, the drop in the liquid level within the preset time is higher than the threshold, indicating that the current water consumption is abnormal. There may be a problem with the water jacket furnace body or the liquid level sensor is faulty. By generating an alarm message, relevant personnel can detect the fault early.

[0022] Furthermore, it also includes a server, and the controller is communicatively connected to the server. The server is used to obtain corresponding temperature data and liquid level data from the controller, count the fluctuations of the corresponding temperature data and liquid level data of each controller within a preset period, mark the controller whose temperature data fluctuations and liquid level data fluctuations are both within the first set value as a sleep controller, and send a sleep control instruction to the sleep controller; the sleep controller is also used to enter a sleep state according to the sleep control instruction.

[0023] Putting a controller whose temperature data fluctuation and liquid level data fluctuation are both within the first set value into sleep mode, in other words, putting a controller whose working state is stable into sleep mode, can reduce energy consumption and reduce the data processing capacity of the server.

[0024] Furthermore, the server is also used to mark a controller whose temperature data fluctuation and liquid level data fluctuation are both greater than a first set value and less than a second set value as a stable controller, and send a frequency reduction control instruction to the stable controller; the stable controller is also used to reduce the collection frequency of temperature data and liquid level data according to the frequency reduction control instruction.

[0025] The controller that makes the fluctuation of temperature data and the fluctuation of liquid level data greater than the first set value and less than the second set value works at a lower acquisition frequency, which can reduce the amount of data processing and maintain only the lowest intensity detection.

[0026] Furthermore, the server is also used to send a frequency increase control instruction to the controller corresponding to the alarm information, and the controller corresponding to the alarm information is also used to increase the collection frequency of temperature data and liquid level data according to the frequency increase control instruction.

[0027] Increasing the collection frequency of the controller corresponding to the alarm information can obtain more complete temperature data and liquid level data, which is convenient for subsequent analysis and processing.

[0028] The second object of the present invention is to provide an intelligent measurement and control method for a water jacket heating furnace, comprising the following contents:

[0029] Collection step: collecting temperature data and liquid level data respectively through the temperature sensor and liquid level sensor arranged in the water jacket furnace body;

[0030] Data acquisition steps: obtaining temperature data and liquid level data through the controller;

[0031] Liquid level height judgment step: judging whether the liquid level is lower than the warning value according to the liquid level data, if it is lower than the warning value, executing the water injection step; then determining the current preset liquid level according to the temperature data and the preset liquid level parameters, judging whether the liquid level is lower than the preset liquid level according to the liquid level data, if it is lower than the preset liquid level, executing the liquid level change judgment step;

[0032] Liquid level change judgment step: judging whether the liquid level is in a rising state according to the liquid level data within a preset time, and if it is not in a rising state, executing the water injection step;

[0033] Water injection step: control the normally closed solenoid valve on the water filling tank on the top of the water jacket furnace body to open.

[0034] Furthermore, it also includes an early warning step: judging whether the temperature is in a stable state based on the temperature data within the preset time; if it is in a stable state, judging whether the liquid level is in a declining state based on the liquid level data within the preset time; if it is in a declining state, judging whether the decline in the liquid level within the preset time is higher than a threshold; if it is higher than the threshold, generating an alarm message.

[0035] The third object of the present invention is to provide an intelligent measurement and control system for a water jacket heating furnace using the above-mentioned device. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Figure 1 It is a front view of the water jacket heating furnace in the first embodiment;

[0037] Figure 2 It is a longitudinal sectional view of the water tank in the first embodiment;

[0038] Figure 3 This is a logic block diagram of the intelligent measurement and control device for a water jacket heating furnace in Example 1. DETAILED DESCRIPTION

[0039] The following is further described in detail through specific implementation methods:

[0040] The symbols in the drawings of the specification include: a water jacket furnace body 1, a water supply tank 2, a main water pipe 3, a first branch pipe 4, a second branch pipe 5, a water level control valve body 6, a connecting rod 7, a float 8, and a normally closed solenoid valve 9.

[0041] Embodiment 1

[0042] The intelligent measurement and control device for the water jacket heating furnace of this embodiment includes: a water jacket furnace body 1, a water tank 2, a water supply pipe, a controller, a normally closed solenoid valve 9, a water level control valve, a liquid level sensor, a temperature sensor and a server.

[0043] like Figure 1 and Figure 2 As shown, the water adding tank 2 is fixed on the top of the water jacket furnace body 1, and the water level control valve is fixed in the water adding tank 2.

[0044] In this embodiment, the water supply pipe includes a main water pipe 3, and a first branch pipe 4 and a second branch pipe 5 connected to the main water pipe 3 via a three-way adapter.

[0045] The water level control valve includes a water level control valve body 6, a connecting rod 7 and a float 8; the float 8 is connected to the water level control valve body 6 through the connecting rod 7; water inlet holes are opened on the side wall and the top of the water tank, and the first branch pipe 4 passes through the water inlet hole on the side wall of the water tank and is connected to the water inlet end of the water level control valve body 6; in this embodiment, the water outlet of the water level control valve body 6 faces downward.

[0046] During installation, it is necessary to control the height of the water level control valve in the water tank 2 according to the water level of the water level control valve so that the float 8 can contact the water surface, and control the opening and closing of the water level control valve body 6 according to the changes in the water surface.

[0047] The normally closed solenoid valve 9 is installed on the water inlet hole at the top of the water tank. The second branch pipe 5 is also connected to the normally closed solenoid valve 9, and the normally closed solenoid valve 9 is electrically connected to the controller.

[0048] The liquid level sensor and the temperature sensor are fixed in the water jacket furnace body 1, and both the liquid level sensor and the temperature sensor are electrically connected to the controller.

[0049] like Figure 3 As shown, the controller is used to obtain liquid level data from the liquid level sensor, and determine whether the liquid level is lower than the warning value according to the liquid level data. If it is lower than the warning value, the normally closed electromagnetic valve 9 is controlled to open. In this embodiment, the warning value is lower than the lowest height of the float ball 8 of the water level control valve. In other words, when the water level is at the warning value, the float ball 8 of the water level control valve does not contact the water surface.

[0050] The controller is also used to obtain temperature data from the temperature sensor, determine the current preset liquid level according to the temperature data and the preset liquid level parameters, and determine whether the liquid level is lower than the preset liquid level according to the liquid level data. If it is lower than the preset liquid level, determine whether the liquid level is in an ascending state according to the liquid level data within the preset time. If it is not in an ascending state, control the normally closed electromagnetic valve 9 to open. In this embodiment, in the preset liquid level parameters, different temperatures correspond to different preset liquid levels, and the higher the temperature, the higher the corresponding preset liquid level; in this embodiment, the liquid level is in an ascending state, which means that the liquid level sampled each time within the preset time is higher than the previous liquid level. In other embodiments, it can also be set according to the sampling rate to select one sample per several intervals for comparison.

[0051] The controller is also used to determine whether the temperature is in a stable state based on the temperature data within a preset time. If it is in a stable state, it is then used to determine whether the liquid level is in a declining state based on the liquid level data within the preset time. If it is in a declining state, it is determined whether the decline in the liquid level within the preset time is higher than a threshold value. If it is higher than the threshold value, an alarm message is generated. In this embodiment, the stable state is determined by calculating the variance of all sampled temperature values ​​within the preset time, and the obtained variance is compared with the set variance value. If it is less than the set variance value, it is considered to be in a stable state. The set variance value can be calculated based on the temperature data of the stable state measured in advance. The judgment of the declining state is similar to that of the rising state.

[0052] The controller is connected to the server for communication. The controller can communicate with the server through a built-in WIFI module or a 4G module, etc. In this embodiment, a 4G module is used.

[0053] The server is used to obtain the corresponding temperature data and liquid level data from the controller, count the fluctuations of the temperature data and liquid level data corresponding to each controller within a preset period, mark the controller whose temperature data fluctuations and liquid level data fluctuations are both within the first set value as a dormant controller, and send a dormant control instruction to the dormant controller; the dormant controller is also used to enter a dormant state according to the dormant control instruction. In this embodiment, the variances of the temperature data and liquid level data within the preset period are calculated respectively to characterize the fluctuations. In this embodiment, the first set value is less than the above-mentioned set variance value; in other embodiments, different first set values ​​can also be set for the temperature data and liquid level data; after entering the dormant state, wake up regularly, for example, every 10 days.

[0054] The server is also used to mark a controller whose temperature data fluctuation and liquid level data fluctuation are both greater than a first set value and less than a second set value as a stable controller, and send a frequency reduction control instruction to the stable controller; the stable controller is also used to reduce the frequency of collecting temperature data and liquid level data according to the frequency reduction control instruction.

[0055] The server is further used to send a frequency increase control instruction to the controller corresponding to the alarm information, and the controller corresponding to the alarm information is further used to increase the frequency of collecting temperature data and liquid level data according to the frequency increase control instruction.

[0056] This embodiment also provides an intelligent measurement and control system for a water jacket heating furnace, using the above-mentioned device.

[0057] Based on the intelligent measurement and control system of the water jacket heating furnace, this embodiment also provides an intelligent measurement and control method for the water jacket heating furnace, including the following contents:

[0058] Collection step: collecting temperature data and liquid level data respectively through the temperature sensor and liquid level sensor arranged in the water jacket furnace body 1;

[0059] Data acquisition steps: obtaining temperature data and liquid level data through the controller;

[0060] Liquid level height judgment step: judging whether the liquid level is lower than the warning value according to the liquid level data, if it is lower than the warning value, executing the water injection step; then determining the current preset liquid level according to the temperature data and the preset liquid level parameters, judging whether the liquid level is lower than the preset liquid level according to the liquid level data, if it is lower than the preset liquid level, executing the liquid level change judgment step;

[0061] Liquid level change judgment step: judging whether the liquid level is in a rising state according to the liquid level data within a preset time, and if it is not in a rising state, executing the water injection step;

[0062] Water injection step: control the normally closed solenoid valve 9 on the water filling tank 2 disposed on the top of the water jacket furnace body 1 to open;

[0063] Early warning steps: determine whether the temperature is in a stable state based on the temperature data within the preset time. If it is in a stable state, determine whether the liquid level is in a declining state based on the liquid level data within the preset time. If it is in a declining state, determine whether the drop in the liquid level within the preset time is higher than the threshold. If it is higher than the threshold, generate an alarm message.

[0064] Embodiment 2

[0065] The difference between this embodiment and embodiment one is that in the device of this embodiment, the server is also used to obtain an inspection plan, which includes the water jacket furnaces to be inspected and the inspection time of each water jacket furnace; the server is also used to determine whether there are dormant controllers corresponding to the water jacket furnaces to be inspected, and if so, to determine whether the number of dormant controllers is greater than 3, and if greater than 3, mark them as test controllers.

[0066] The server is also used to determine the test time according to the inspection time corresponding to the water jacket furnace. The test time is 5-12 hours ahead of the inspection time. In this embodiment, it is 10 hours ahead. The server is also used to send a test control instruction to the test controller at the test time; the controller is also used to control the normally closed solenoid valve to open after receiving the test control instruction, until the liquid level rises to the preset maximum liquid level according to the liquid level data, and then control the normally closed solenoid valve to close.

[0067] The server is also used to mark the liquid level data and temperature data corresponding to the liquid level from the preset maximum liquid level to the preset liquid level as test temperature data and test liquid level data, respectively, among the temperature data and liquid level data uploaded by the test controller, wherein each test controller uses the same preset liquid level.

[0068] The server is also used to draw the temperature change curve and the liquid level change curve according to the test temperature data and the test liquid level data. Taking the temperature data as an example, the temperature change curve is drawn with the temperature as the ordinate and the time as the abscissa. The liquid level change curve is drawn in the same way. The temperature change curves corresponding to each water jacket furnace are superimposed in the same coordinate system to generate a temperature change graph, and the liquid level change curves corresponding to each water jacket furnace are superimposed in the same coordinate system to generate a liquid level change graph; the server is also used to package the temperature change graph and the liquid level change graph into inspection auxiliary information.

[0069] The method of this embodiment also includes a detection step: obtaining an inspection plan, the inspection plan including the water jacket furnaces to be inspected and the inspection time of each water jacket furnace; determining whether there are dormant controllers corresponding to the water jacket furnaces to be inspected, and if so, determining whether the number of dormant controllers is greater than 3, and if so, marking them as test controllers;

[0070] The test time is determined according to the inspection time corresponding to the water jacket furnace, and a test control instruction is sent to the test controller at the test time; after receiving the test control instruction, the controller controls the normally closed solenoid valve to open, until the liquid level rises to the preset maximum liquid level according to the liquid level data, and then controls the normally closed solenoid valve to close.

[0071] In the temperature data and liquid level data uploaded by the test controller, the liquid level data and temperature data corresponding to the liquid level from the preset maximum liquid level to the preset liquid level are marked as test temperature data and test liquid level data, respectively, wherein each test controller uses the same preset liquid level.

[0072] The temperature change curve and the liquid level change curve are drawn according to the test temperature data and the test liquid level data. Taking the temperature data as an example, the temperature change curve is drawn with the temperature as the ordinate and the time as the abscissa. The liquid level change curve is drawn in the same way. The temperature change curves corresponding to each water jacket furnace are superimposed in the same coordinate system to generate a temperature change graph, and the liquid level change curves corresponding to each water jacket furnace are superimposed in the same coordinate system to generate a liquid level change graph; the temperature change graph and the liquid level change graph are packaged as inspection auxiliary information.

[0073] Since the controller is in a dormant state, it is impossible to obtain relevant data and the working status of the liquid level sensor, temperature sensor and water jacket furnace. In this embodiment, water is injected to the preset maximum liquid level before the inspection to change the temperature and water level to test whether the liquid level sensor and temperature sensor are working properly. The temperature change graph and liquid level change graph come from more than 3 water jacket furnaces, which is helpful for subsequent inspection personnel to conduct comparative analysis and find problems such as abnormal leakage of the water jacket furnace or failure of the liquid level sensor and temperature sensor, which can improve the inspection effect.
