[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0020] Example 1: This embodiment provides a steam quality evaluation method. By using measured data such as steam pressure, temperature, and dryness fraction within the pipeline, the method for calculating steam enthalpy is optimized. Based on this, enthalpy difference and dryness fraction are considered to correct for steam quality, thereby achieving quantitative judgment of steam quality and accurate assessment. The method includes: S1. Data Collection: Optionally, the temperature of the steam can be collected in real time at a sampling interval of 1 second using various steam data sensors such as temperature sensors, pressure sensors, and dryness sensors installed inside the steam outlet pipe. T ,pressure P and dryness X data.

[0021] S2, Data Processing: Optionally, the collected data can be filtered and amplified using a signal conditioning circuit.

[0022] S3. Calculation of specific heat capacity at constant pressure: Optionally, temperature-dependent isobaric specific heat capacity can be introduced. To achieve dynamic and accurate calculation of steam enthalpy, a constant value is no longer used; instead, a temperature polynomial fitting method is employed to correct the isobaric specific heat capacity of steam. ; in, Specific heat capacity at constant pressure The corresponding unitless specific heat capacity at constant pressure; a , b and c These are constants calibrated based on actual measurements; For temperature T The corresponding unitless current steam temperature value.

[0023] It should be noted here that, under the premise of constant pressure, the results were obtained by fitting multiple temperatures and the specific heat capacity corresponding to multiple temperatures. At that time, only the specific heat capacity at constant pressure is utilized. and temperature T The value.

[0024] And through temperature T and Determine the specific heat capacity at constant pressure At that time, the temperature T Corresponding temperature value Substituting the values, we obtain the isobaric specific heat capacity. Then, the specific heat capacity at constant pressure is determined by adding units. Corresponding specific heat capacity at constant pressure That's all.

[0025] For example, when the pressure is 0.1 MPa and the steam temperature is 200℃: ; ; Corresponding: ; Optionally, the input T during the fitting calculation should be in degrees Celsius (°C). If the input temperature unit is K, it needs to be converted to degrees Celsius (°C) (-273.15). The unit of the fitting calculation result can be KJ / (kg·K) or KJ / (kg·°C), because a temperature difference of 1°C is equal to a temperature difference of 1 K, and using KJ / (kg·K) is the standard notation of SI units.

[0026] S4, based on temperature T and pressure P Data, calculate steam enthalpy. h and enthalpy difference : S4.1 Determine the enthalpy of saturated vapor ( h sat ): Based on current pressure P Query the international steam table to obtain the corresponding saturation temperature The enthalpy value is obtained by taking the enthalpy value of the saturated vapor. h sat .

[0027] S4.2 Determine the actual steam enthalpy h actual : If the steam inside the pipe is saturated steam, then h actual =h sat ; If the steam inside the pipe is superheated steam, the calculation formula is: ; enthalpy difference ( ): ; When determining steam quality, in addition to considering enthalpy difference, the actual impact of steam dryness is also taken into account. Therefore, this embodiment establishes a comprehensive steam quality factor. Q Used to quantify the quality level of steam:

[0028] in, X Steam dryness is the percentage of dry steam mass in a saturated steam mixture, which can be obtained by a dryness detection sensor and is dimensionless; it is measured in real time by the dryness monitoring sensor. These are weighting coefficients, configured according to the industrial application scenario.

[0029] Q This is a comprehensive steam quality factor, with a numerical range of [0, 1], used to determine the steam grade. Steam quality comprehensive factor Q When the value is greater than or equal to the first preset value, the steam is defined as high-quality steam; optional, Q ≥0.85: High-quality steam, with a significantly higher heat price, suitable for highly dry applications such as pharmaceuticals and food processing; Steam quality comprehensive factor Q When the value is greater than or equal to the second preset value and less than the first preset value, the steam is defined as medium-quality steam; optionally, 0.6≤Q<0.85: medium-quality steam, with a slightly higher heat price, suitable for general industrial applications, such as heating, power equipment, etc. When the comprehensive steam quality factor is less than the second preset value, the steam is defined as low-quality steam; optionally, Q < 0.6: low-quality steam, charged according to the basic heat price, usually used in less stringent applications, or as initial steam for further processing.

[0030] An alarm will be triggered if the comprehensive steam quality factor is less than the third preset value; if Q < 0.4 and A value less than 0 indicates a sensor malfunction or excessively high steam moisture content, triggering a local alarm and sending a warning message to the cloud. Maintenance personnel then issue commands via the cloud. At this time, the terminal detects and calibrates the temperature and pressure sensors to ensure they are functioning correctly; checks the connection and operational status of the data acquisition system; and checks for leaks in the steam pipeline, repairing any leaks.

[0031] Example 2: Current smart heat price meters lack dynamic compensation mechanisms when pressure or temperature fluctuates, resulting in poor measurement stability. Furthermore, traditional flow meters output only flow rate data, failing to adequately consider the impact of steam quality, thus failing to directly link costs to actual heat energy consumption and compromising economic fairness.

[0032] Based on this, this embodiment also provides an intelligent heat price meter based on steam enthalpy difference measurement, which can calculate the actual heat provided according to the steam quality and charge dynamically accordingly. The intelligent heat price meter in this embodiment implements the method in Embodiment 1.

[0033] like Figure 2 and Figure 3 As shown, the intelligent heat price meter in this embodiment optimizes the calculation method of steam enthalpy by measuring data such as steam pressure, temperature, and dryness in the pipeline. Based on this, it corrects the steam quality by considering enthalpy difference and dryness, thereby realizing the quantitative judgment of steam quality and pricing according to quality.

[0034] As steam flows through the meter, the steam temperature is collected in real time at 1-second sampling intervals by a steam data sensor installed inside the steam outlet pipe. T ,pressure P and dryness X The data acquisition system connects to the sensors, and the sensor selection ensures that the measurement range covers the temperature, pressure, and dryness of the steam. The sensor signal is filtered and amplified by the signal conditioning circuit before being transmitted to the enthalpy calculation module, which calculates the enthalpy difference based on the steam data. and comprehensive factors of steam quality Q The calculation results are transmitted to the heat price adjustment module, which can then adjust the heat price based on the comprehensive steam quality factor. Q The system determines steam quality and sets the steam price accordingly. The enthalpy calculation module and the heat price adjustment module are integrated into a separate calculation unit module located outside the heat price meter. This module is equipped with an LCD display that shows the current steam data and can adjust different heat price strategies based on various industrial scenarios via a communication module.

[0035] like Figure 4 and Figure 5 As shown, this embodiment introduces temperature-dependent isobaric specific heat capacity. To achieve dynamic and accurate calculation of steam enthalpy, a constant value is no longer used; instead, a temperature polynomial fitting method is employed to correct the isobaric specific heat capacity of steam. ; in, Specific heat capacity at constant pressure The corresponding unitless specific heat capacity at constant pressure; a , b and c These are constants calibrated based on actual measurements; For temperature T The corresponding unitless current steam temperature value.

[0036] It should be noted here that, under the premise of constant pressure, the results were obtained by fitting multiple temperatures and the specific heat capacity corresponding to multiple temperatures. At that time, only the specific heat capacity at constant pressure is utilized. and temperature T The value.

[0037] And through temperatureT and Determine the specific heat capacity at constant pressure At that time, the temperature T Corresponding temperature value Substituting the values, we obtain the isobaric specific heat capacity. Then, the specific heat capacity at constant pressure is determined by adding units. Corresponding specific heat capacity at constant pressure That's all.

[0038] When the enthalpy calculation module receives the temperature T and pressure P When processing the data, begin calculating the vapor enthalpy h: saturated vapor enthalpy h sat Based on the current pressure P Consult the international steam table to obtain the enthalpy value at the corresponding saturation temperature.

[0039] Actual steam enthalpy h actual Calculation: If the steam inside the pipe is saturated steam, then h actual =h sat ; If the steam inside the pipe is superheated steam, the calculation uses the following formula: ; enthalpy difference for: ; When determining steam quality, in addition to considering enthalpy difference, the actual impact of steam dryness is also taken into account. Therefore, this invention establishes a comprehensive steam quality factor. Q Used to quantify the quality level of steam: ; in, X Steam dryness is measured in real time using a dryness monitoring sensor. These are weighting coefficients, configured according to the industrial application scenario.

[0040] Q As a comprehensive factor for steam quality, its numerical range is [0, 1], and it is used to determine the steam grade: Q≥0.85: High-quality steam, with a significantly higher heat price, suitable for highly dry applications such as pharmaceuticals and food processing; 0.6≤Q<0.85: Medium-quality steam, with a moderately higher heat price, suitable for general industrial applications such as heating and power equipment; Q<0.6: Low-quality steam, charged at the base heat price, typically used for less demanding applications or as initial steam for further processing.

[0041] If Q < 0.4 and A value less than 0 indicates a sensor malfunction or excessively high steam moisture content, triggering a local alarm and sending a warning message to the cloud. Maintenance personnel then issue commands via the cloud. At this time, the terminal detects and calibrates the temperature and pressure sensors to ensure they are functioning correctly; checks the connection and operational status of the data acquisition system; and checks for leaks in the steam pipeline, repairing any leaks.

[0042] Billing standards are based on real-time calculations. Q The system dynamically adjusts and generates billing records. The calculation unit transmits the corresponding billing standard for steam to the meter installed on the pipeline in real time, and calculates the actual heat supply and heat price based on the flow meter in the pipeline. The heat price meter is equipped with an LCD display screen that can display the current heat price, cumulative heat price, and cumulative heat supply in real time.

[0043] In other embodiments, the heat price per unit time is based on the steam mass flow rate. m enthalpy value h and heat price p Calculate the cost of heat per unit time .

[0044] ; The cumulative heat price is accumulated based on the actual steam supply time. The data is uploaded to the cloud server through the 4G / WIFI module inside the heat price meter, supporting remote monitoring, historical data query and billing report generation.

[0045] One of the working principles or processes of the intelligent heat price meter in this embodiment is as follows: When steam flows from steam inlet 5 through heat price meter 1, the flow meter inside heat price meter 1 measures the mass flow rate per unit time. m The steam data sensor at temperature and pressure measurement point 2 collects the steam temperature in real time at a sampling interval of 1 second. T ,pressure P and dryness X The data acquisition system 7 converts the measured steam data from the steam outlet 5 into an electrical signal, which is then transmitted via the transmission pipe 3 to the enthalpy calculation module 8. The enthalpy calculation module 8 can calculate the enthalpy difference based on the steam data. and comprehensive factors of steam quality Q Steam data can be displayed in real time on the LCD screen of the computing unit module 4. The heat price adjustment module 10 has a built-in preset tiered heat price strategy, which is based on the comprehensive steam quality factor. Q Steam is divided into different steam heat prices. p The heat price strategy can be changed according to different industrial scenarios through the communication module 11 in the calculation unit 4. If the comprehensive steam quality factor... Q <0.4 and If the value <0 remains negative, alarm module 9 determines it as a sensor malfunction or excessively high steam moisture content, triggering a local alarm and sending a warning message to the cloud. Heat price adjustment module 10 adjusts the steam heat price. p The data is transmitted to heat price meter 1, which can then measure the mass flow rate. m Steam heat price p and vapor enthalpy h Calculate the heat price per unit time. P 0. The heat price meter 1 is equipped with an LCD display screen, which can display the cumulative heat price cost in real time. P Cumulative heating costs P Calculated based on actual steam supply time. Furthermore, the cost data can be uploaded to the cloud server via the 4G / WIFI module inside the heat price meter 1, supporting remote monitoring, historical data query, and billing report generation.

[0046] The intelligent heat price meter provided in this embodiment uses a calculation unit and a flow meter as its core. The calculation unit calculates the enthalpy difference of the steam before and after the flow based on the temperature and pressure measured at the steam outlet. It then classifies the steam into different qualities based on a comprehensive steam quality factor. Different qualities of steam correspond to different heating policies and heat prices. The final real-time heat price is calculated using the flow rate measured by the flow meter. This intelligent heat price meter based on steam enthalpy measurement provides accurate measurement of the user's heat consumption. By correcting for steam quality using parameters such as temperature, pressure, dryness, and enthalpy, it achieves quality-based pricing, effectively improving the accuracy and stability of steam quality judgment. It is particularly suitable for fluctuating operating conditions and high-calorific-value-sensitive industrial processes, demonstrating significant feasibility and long-term benefits.
