Description
Technical Field
Embodiments of the present disclosure relate to the field of energy technologies, and in particular, to a method, an apparatus, an electronic device, and a medium for determining a saturation temperature of water vapor.
Background
Industrial boilers for producing high-temperature and high-pressure steam are widely used in various industrial fields, and the produced steam is used for heating, process manufacturing and the like. Steam produced by an industrial steam boiler is generally steam, and the temperature of the steam is higher than that of saturated steam under the same pressure. Because a steam boiler generally only has corresponding temperature, pressure and flow measurement points, the superheat degree of output steam cannot be directly obtained, and the steam thermodynamic calculation is the basis of the heat balance calculation of an industrial thermodynamic system, the saturation temperature of the steam is usually required to be calculated, so that the superheat degree of the steam is calculated, and the phase state of working medium water under corresponding absolute pressure is judged.
When the pressure of liquid flowing to a certain position in a flow passage of the water pump is equal to or lower than the corresponding vaporization pressure, the liquid can be vaporized to generate a large amount of bubbles, and when the bubbles flow to a high-pressure area, the bubbles are quickly condensed and broken under the action of high pressure, and great and repeated impact is formed on materials on the surface of the flow passage to cause fatigue erosion or denudation, namely water pump cavitation.
The damage of water pump cavitation:
noise and vibration
In the process of cavitation of the water pump, from a suction inlet (low-pressure area) to a water outlet (high-pressure area) of the water pump, a large number of bubbles are continuously generated, developed, condensed and broken to bring repeated continuous high-speed impact and great pulsating force, and serious noise and severe vibration can be caused along with the impact.
② damage to water pump material
Because a large amount of bubbles are generated and broken continuously to bring high-speed impact, a great pulse impact force is formed and is repeatedly and continuously acted on the surface of a water pump flow passage, so-called 'weeping rock', and metal materials are often damaged or failed due to the severe test that the metal materials cannot bear.
Hydraulic performance is greatly reduced
When the water pump generates cavitation, the flow is reduced (the smaller the flow channel is, the more serious the flow channel is), the speed and the direction of the water flow are changed, the energy obtained by the fluid from the impeller blade is reduced, and the lift of the water pump is greatly reduced. At present, the saturation temperature of water vapor is mainly obtained by looking up a thermodynamic diagram or table of water and water vapor according to the absolute pressure of the water vapor.
However, the above method of looking up the thermodynamic property diagrams or tables of water and steam is a conventional method of thermodynamic calculation of water and steam, and because the thermodynamic property diagrams or tables of water and steam are complicated, it is necessary to manually mark the corresponding saturation temperatures in the thermodynamic property diagrams or tables of water and steam according to the pressure of water and steam, and the method is time-consuming and labor-consuming and has no real-time calculation capability.

The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Fig. 1 is a schematic diagram of one application scenario of a method of determining a saturation temperature of water vapor according to some embodiments of the present disclosure.
In the application scenario of FIG. 1, first, the computing device 101 may obtain the absolute pressure 102 of the water vapor. The computing device 101 may then determine a saturation temperature 104 of the water vapor using a higher order function 103 based on the absolute pressure 102.
The computing device 101 may be hardware or software. When the computing device is hardware, it may be implemented as a distributed cluster composed of multiple servers or terminal devices, or may be implemented as a single server or a single terminal device. When the computing device is embodied as software, it may be installed in the hardware devices enumerated above. It may be implemented, for example, as multiple software or software modules to provide distributed services, or as a single software or software module. And is not particularly limited herein.
It should be understood that the number of computing devices in FIG. 1 is merely illustrative. There may be any number of computing devices, as implementation needs dictate.
With continued reference to fig. 2, a flow 200 of some embodiments of a method of determining a saturation temperature of water vapor according to the present disclosure is shown. The method may be performed by the computing device 101 of fig. 1. The method for determining the saturation temperature of the water vapor comprises the following steps:
in step 201, the absolute pressure of the water vapor is obtained.
In some embodiments, the performing entity (e.g., computing device 101 shown in FIG. 1) of the method of determining the saturation temperature of water vapor may obtain the absolute pressure of water vapor through a wired connection or a wireless connection. As an example, the execution body may receive an absolute pressure input by a user as the absolute pressure of the water vapor. As another example, the execution main body may be connected to another electronic device by a wired connection method or a wireless connection method, and an absolute pressure of water vapor stored in the connected electronic device is acquired as the absolute pressure of the water vapor.
It should be noted that the wireless connection means may include, but is not limited to, a 3G/4G connection, a WiFi connection, a bluetooth connection, a WiMAX connection, a Zigbee connection, a uwb (ultra wideband) connection, and other wireless connection means now known or developed in the future.
In some embodiments, the execution body may substitute the absolute pressure into the high-order function to obtain the saturation temperature of the water vapor.
In some optional implementations of some embodiments, the higher-order function is obtained by: acquiring a training sample set, wherein training samples in the training sample set comprise sample absolute pressure of sample water vapor; substituting the sample absolute pressure of the sample water vapor in the training sample into a standard saturation temperature formula to obtain the sample saturation temperature of the sample water vapor; calculating the standard saturation temperature of the sample water vapor according to the thermodynamic property table of water and water vapor and the sample absolute pressure of the sample water vapor; determining a saturation temperature error based on the sample saturation temperature and the standard saturation temperature; generating a higher order function based on the saturation temperature error. Here, the execution body may obtain a difference by subtracting the standard saturation temperature from the sample saturation temperature of the sample water vapor. Then, the execution body may determine the difference as the saturation temperature error.
The standard saturation temperature formula set forth above refers specifically to the general industrial water and water vapor thermodynamic calculation formula. As an example, the standard saturation temperature formula may be the prior art International general Industrial Water and steam thermodynamic calculation formula — the IAPWS-IF97 formula. The standard saturation temperature formula can be corrected according to engineering requirements, and a formula which meets the actual pressure interval and takes calculation precision and speed into consideration is fitted.
In some optional implementations of some embodiments, the generating a higher order function based on the saturation temperature error includes: determining whether the saturation temperature error meets a preset condition; in response to determining that the standard saturation temperature formula is not satisfied, adjusting parameters of the standard saturation temperature formula to obtain an adjusted standard saturation temperature formula; determining an adjusted saturation temperature error based on the adjusted standard saturation temperature formula; determining the adjusted standard saturation temperature formula as the high order function in response to determining that the adjusted saturation temperature error satisfies the preset condition. Here, the preset condition may be that the saturation temperature error value is not greater than a preset value.
The above-stated saturation temperature error after adjustment satisfies the predetermined condition, which means that the convergence degree of the saturation temperature error is relatively high, and therefore, the accuracy of the calculation result obtained by using the high-order function is relatively high. It should be noted that the amount of sample water vapor should be large to ensure the accuracy of the fitted higher order function. Therefore, the saturation temperature error should be a saturation temperature error including a large amount of sample water vapor respectively. Optionally, the adjusted saturation temperature errors meet the preset condition, where a sum of saturation temperature errors corresponding to the multiple sample superheated water vapors is not greater than a preset value, or a saturation temperature error corresponding to each sample superheated water vapor is not greater than a preset value.
In some alternative implementations of some embodiments, the above method may be adapted to the saturation temperature of other thermodynamic working fluids, fitting the derivation of higher order functions of absolute pressure.
In some optional implementations of some embodiments, the above-mentioned higher-order function may be represented as follows:
t(P)＝-10.9858534680823×P1.5+87.0639896853169×P1.25-282.92113545391×P+487.911303047971×P0.75-483.854281154476×P0.5+440.701716149279×P0.25-58.0848701830052。
wherein P represents the absolute pressure of water vapor in MPa. T represents the saturation temperature of water vapor in degrees C.
In some alternative implementations of some embodiments, the accuracy of the calculation of the higher order function is illustrated by a relative error (which refers to a value obtained by multiplying the ratio of the absolute error caused by the measurement to the measured (agreed) true value by 100%, expressed as a percentage) that is more reflective of the trustworthiness of the measurement, and the data and calculation results are shown in the following table:
through comparison of experimental data, the maximum value of the relative error of the predicted thermal efficiency is 1.447633764%, and the minimum value is only 0.002355149%. Through comparison of test data, it can be seen that the method provided by the embodiment has very high accuracy in calculating the saturation temperature of the water vapor.
In some optional implementations of some embodiments, the method further comprises: transmitting the saturation temperature of the water vapor to a target device with a display function, and controlling the target device to display the saturation temperature of the water vapor.
One of the above-described various embodiments of the present disclosure has the following advantageous effects: the absolute pressure of the water vapor is obtained, and the saturation temperature of the water vapor can be determined by using a high-order function. The method disclosed by the embodiment does not need manpower, marks the corresponding saturation temperature in the thermodynamic property diagram or table of the water and the steam according to the pressure of the steam, saves time and labor, has real-time calculation capability, and can accurately determine the saturation temperature of the steam. In addition, the method has universality, is suitable for saturation temperatures of other thermodynamic working media, and is fit to derivation of a high-order function of absolute pressure.
