Description

Technical Field

[0001] The present invention relates to the technical field of thermal measurement of fluid heat exchange processes, and more specifically to a temperature control method and system for a distributed flow calorimeter gas-liquid separation device. Background Art

[0002] Distributed flow calorimeter is an experimental instrument for measuring the thermal properties of high-pressure fluids. It can monitor the changes in thermodynamic parameters of the fluid in the pipeline in real time. Its core idea is to start from the differential point of view and based on the principle of conservation of energy, regard each microelement of the pipeline as a research object, so as to achieve accurate measurement of fluid properties. This instrument is often used to measure and screen endothermic hydrocarbon fuels, and is of great significance to fields such as aerospace. The overall distributed flow calorimetry system can be divided into four modules, namely: injection module, calorimetric module, gas-liquid separation module and data sampling module. The gas-liquid separation module is responsible for separating and collecting the gas and liquid produced after the thermal cracking of the fluid measured by the instrument, so as to facilitate subsequent research on the reaction characteristics of the fluid.

[0003] In the above-mentioned fields, since the measured fluid reaction process is carried out under high pressure, the gas products generated in the gas-liquid separation module have a process from high pressure to normal pressure during transportation. On the one hand, it will cause the gas products to expand rapidly and absorb heat, thereby freezing the gas transmission pipeline, causing pipeline blockage or even deformation and cracking, and the gas products are difficult to collect; on the other hand, the heat absorption process of the gas products also reflects the thermodynamic properties of the gas products. Measuring their thermodynamic parameters is conducive to the subsequent further analysis and research on the composition and characteristics of the products.

[0004] In summary, in view of the particularity of the application field and working conditions of the distributed flow calorimeter, the present invention proposes a temperature control method and system for the gas-liquid separation device of the distributed flow calorimeter. The present invention is based on the principles of thermodynamics and energy conservation. By real-time monitoring and conditioning of the temperature of the gas pipeline, the heating power of the gas pipeline is controlled in real time to stabilize the temperature of the gas pipeline within a certain temperature range, thereby ensuring the smooth flow of the pipeline and the stability of the gas products. The thermodynamic parameters of the gas products are further deduced through this method and system. Summary of the invention

[0005] In response to the problems mentioned in the background technology, the present invention provides a temperature control method and system for a distributed flow calorimeter gas-liquid separation device to address the shortcomings of the prior art, determine the parameter settings and operation strategies of the heating system under different temperature conditions, and establish a fast and efficient temperature control system.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] The present application provides a temperature control method for a gas-liquid separation device of a distributed flow calorimeter, comprising the following steps:

[0027] S1. Starting from the gas pipeline inlet of the gas-liquid separation device, build a gas pipeline in an adiabatic environment;

[0028] S2, obtaining temperature data of the inlet and outlet of the gas transmission pipeline and the surface of the pipeline;

[0029] S3, dynamically compensate the voltage signal to reduce the measurement value deviation;

[0030] S4, fitting a polynomial about temperature and heating power to obtain a functional relationship between the difference between the current temperature and the target temperature and the required heating power;

[0031] S5. Adjust the heating power according to the functional relationship to ensure that the overall temperature of the gas pipeline remains constant.

[0032] Furthermore, S2 sets temperature collection units at both ends and the outer wall of the gas pipeline to obtain the temperature values ​​of the gas pipeline inlet, outlet and pipeline surface in real time.

[0033] Further, the S3 is specifically:

[0034] A dynamic compensator is added at the output end of the temperature acquisition unit to eliminate the error caused by response lag. The compensator model is expressed as:

[0035]

[0036] Among them, T Comp,i is the collected temperature value after compensation, T Tc,i and T Tc,i-1 are two adjacent temperature values ​​collected by the temperature acquisition unit, and τ1 is the dynamic response time constant of the sample.

[0037] Furthermore, the gas transmission pipeline adopts a metal shell, and the insulation material is assembled inside the cavity of the metal shell using positioning pieces and sealing pieces at both ends, and a multi-layer insulation structure is adopted inside the shell.

[0038] Further, the S4 is specifically:

[0039] S4.1, fitting a polynomial about gas pipeline temperature and heating power;

[0040] S4.2, calculating relevant parameters in the polynomial;

[0041] S4.3. Obtain the functional relationship between the difference between the collected temperature and the target temperature and the required heating power:

[0042]

[0043] Among them, K p , K i and K d are the parameters that play the role of proportion, integration and differentiation respectively. e(k), e(k-1) and e(k-2) are the temperature values ​​collected three times continuously on the surface of the gas pipeline.

[0044] Furthermore, S5 is specifically as follows: adjusting the heating power according to the functional relationship, adopting a multi-stage heating method, if the collected temperature is lower than the target temperature, increasing the heating power of the corresponding segment, if the collected temperature is higher than the target temperature, reducing the heating power of the corresponding segment or stopping heating.

[0045] In a specific embodiment, the temperature control method for a distributed flow calorimeter gas-liquid separation device further includes:

[0046] S6. When the overall temperature of the gas pipeline remains constant, the inlet and outlet temperatures are measured and the total heating power is calculated to accurately deduce the relationship between the thermophysical parameters of the fluid and the physical and chemical changes of the gas products.

[0047] Furthermore, the relationship between the thermal characteristic parameters and the physical and chemical changes of the gas products includes: the heat flux density of the gas products, the changing relationship between the pressure and volume of the gas products, the work done by the gas on the outside, the change in entropy of the gas products, the change in enthalpy of the gas products and the change in Gibbs energy of the gas products.

[0048] like Figure 1 As shown, the embodiment of the present application discloses a temperature control method for a gas-liquid separation device of a distributed flow calorimeter, and the specific steps are as follows:

[0049] Step 1: Starting from the gas pipeline inlet of the gas-liquid separation device, build a gas pipeline in an insulating environment through a metal shell and thermal insulation materials to reduce the impact of heat loss during the heat exchange process.

[0050] In this embodiment, the metal shell is made of stainless steel, with positioning and sealing parts at both ends, and a multi-layer insulation structure is used inside the shell: an air insulation layer and aluminum silicate fiber insulation cotton are used to make the shell have good thermal insulation performance.

[0051] Step 2: Install thermocouples at the inlet and outlet of the constructed gas pipeline and on the pipeline surface to obtain the inlet and outlet temperature data of the gas product and the temperature data of the pipeline surface in real time.

[0052] Step 3: Since the dynamic characteristics of thermocouples are limited by the process, the signal response has a certain hysteresis, resulting in a certain deviation between the measured value and the current true value. Therefore, a dynamic compensator is added to extend the working frequency band of thermocouple measurement and eliminate the error caused by response lag. In order to ensure the real-time performance of temperature data, it is necessary to dynamically compensate the voltage signal of the thermocouple response to improve the dynamic response speed of the device, so as to accurately collect temperature.

[0053] A dynamic compensator is added at the output end of the thermocouple to achieve the effect of dynamic compensation. The compensator model of the thermocouple is expressed as formula (1):

[0054]

[0055] Among them, T Comp,i is the collected temperature value after compensation (K); T Tc,i and T Tc,i-1 are the two adjacent temperature values ​​collected (K); τ1 is the dynamic response time constant of the sample thermocouple.

[0056] Step 4: Use the incremental PID algorithm to control the heating power of the gas pipeline.

[0057] The temperature collected by the thermocouple is compared with the target temperature in real time, and a polynomial about temperature and heating power is fitted. Then, the relevant parameters in the polynomial are calculated by the self-tuning method to obtain the functional relationship between the difference between the current temperature and the target temperature and the required heating power. The form is generally formula (2):

[0058]

[0059] Among them, K p , K i and K d are the parameters that play the role of proportion, integration and differentiation respectively, and can be solved by the self-tuning method; e(k), e(k-1) and e(k-2) are the collected temperature values ​​of three consecutive samples of the thermocouple on the surface of the gas pipeline.

[0060] Step 5: The heating power is regulated by the polynomial fitted in step 4. A multi-stage heating method is adopted. If the temperature collected by the thermocouple is lower than the target temperature, the heating power of the corresponding section is increased. If the collected temperature is higher than the target temperature, the heating power of the corresponding section is reduced or the heating is stopped, so as to ensure that the overall temperature of the gas pipeline remains constant. According to the law of conservation of energy, the total heating power can be inferred to be formula (3):

[0061]

[0062] Among them, P Heater P is the total heating power of the heating wire or heating plate; Loss is the total heat loss power in the process; P Fluid It is the total heat absorption power of the gas product due to expansion and heat absorption at the separator outlet due to pressure reduction. Heater It can be accurately calculated by controlling the heating module, and P Loss Due to the adiabatic environment, the impact is small, usually expressed as formula (4):

[0063]

[0064] Where K is the heat dissipation constant of the device, the unit is W / K, T i is the steady-state temperature of each heating section of the gas pipeline. The heat dissipation constant K can be obtained by calibration.

[0065] Step 6: When the overall temperature of the gas pipeline remains constant, the thermophysical parameters of the fluid and the relationship between the physicochemical change process of the gas product and the thermophysical parameters can be accurately calculated by measuring the inlet and outlet temperatures and calculating the total heating power.

[0066] The heat absorption power of the gas product can be calculated by equation (3) and equation (4), and the heat flux density of the gas product can be expressed by equation (5):

[0067]

[0068] Where q is the heat flux of the gas product, d is the inner diameter of the pipe, and l is the length of the pipe.

[0069] Since the temperature of the outer wall of the pipeline is constant, the flow of the gas product inside the pipeline can be approximately regarded as occurring under isothermal conditions. The relationship between the pressure and volume of the gas product can be obtained through the ideal gas state equation and can be expressed by formula (6):

[0070]

[0071] Among them, p1 is the internal pressure of the separator, which can be obtained through the pressure sensor at the pipeline inlet, V1 is the volume of the gas product under pressure p1, p2 is the pipeline outlet pressure, which can be obtained through the pressure sensor at the pipeline outlet, and V2 is the volume of the gas product under pressure p2.

[0072] In the isothermal process, the gas changes from high pressure to low pressure, and its volume will change accordingly. The amount of heat absorbed Q is equal to the amount of work done by the gas to the outside. According to the definition of the isothermal process, the work done by the gas to the outside can be expressed by formula (7):

[0073]

[0074] Where n is the amount of substance in the gas product, R is the molar gas constant, and T is the temperature of the gas product at steady state.

[0075] Furthermore, the change in entropy of the gas product during this process, ΔS, can be expressed by equation (8):

[0076]

[0077] Under isothermal conditions, the volume and pressure of an ideal gas are inversely related, following Boyle's law. The change in enthalpy of the gas product during this process, △H, can be approximately expressed by equation (9):

[0078]

[0079] Where ΔP is the change in the pressure of the gas product.

[0080] Furthermore, the change in Gibbs energy of the gas product during this process, △G, can be expressed by equation (10):

[0081] like Figure 2As shown, an embodiment of the present application discloses a temperature control system for a distributed flow calorimeter gas-liquid separation device, which mainly includes a heat preservation module, a signal acquisition module, a heating module and a main control module.

[0082] The thermal insulation module is used to construct an insulating environment to reduce the impact of heat loss caused by environmental factors.

[0083] The signal acquisition module is used to detect the inlet and outlet temperatures of the gas products and the temperatures of each heating section of the gas pipeline in real time and perform dynamic compensation, collect data on the inlet and outlet pressures of the pipeline, and detect the mass flow of the gas products in real time.

[0084] The heating module divides the gas pipeline into multiple sections and heats the pipeline in each section. If the temperature of the gas pipeline is lower than the target temperature, the heating power is increased; if the temperature of the gas pipeline is higher than the target temperature, the heating power is reduced or the heating is stopped.

[0085] The main control module is used to acquire and compensate temperature data and fit the functional relationship between temperature and heating power, so as to regulate the power of the heating module.

[0087] The aluminum silicate fiber insulation cotton 2 is assembled inside the cavity of the metal shell 1 and fixed by sealing members and positioning members to ensure the stability of the internal environment.

[0088] The heating wire or heating sheet 3 is evenly covered on the outer wall of the gas pipeline 4 by winding and bonding, so that each heating section can evenly heat the pipeline.

[0089] The inlet thermocouple 5, outlet thermocouple 6 and pipeline surface thermocouple 7 are fixed to the inlet and outlet ends of the gas pipeline 4 and the outer wall surface at the center of each heating section of the gas pipeline by welding, and the purpose is to measure the inlet and outlet temperatures of the gas products and the outer wall temperature of each heating section pipeline in real time.

[0090] The gas-liquid separator 8 is a device for separating the gas and liquid from the outlet product of the distributed flow calorimeter.

[0091] The mass flow meter 10 is a device for measuring the flow of gas products inside the gas pipeline, and can provide data for solving the thermal physical property parameters of the gas products.

[0092] The pipeline inlet pressure sensor 11 and the pipeline outlet pressure sensor 12 are used to detect the pipeline inlet pressure and the pipeline outlet pressure in real time, respectively.

[0093] The main control module 9 is electrically connected to the heating wire or heating plate 3, the inlet thermocouple 5, the outlet thermocouple 6, the pipeline surface thermocouple 7, the mass flow meter 10, the pressure sensor 11 at the pipeline inlet and the pressure sensor 12 at the pipeline outlet. It is mainly used to obtain the data collected by the sensor, control the heating power of the heating wire or heating plate 3, communicate with the remote terminal, and display and save relevant data.

[0094] Furthermore, the relevant data displayed and saved include: temperature data collected by the thermocouple, flow data collected by the flowmeter, pressure data collected by the pressure sensor, the heating power of the system, the polynomial function fitted by the temperature control algorithm, and relevant parameters of the sensor dynamic compensation method.
