DETAILED DESCRIPTION
[0027] It is easy to understand that according to the technical scheme of the present application, a person skilled in the art can propose a plurality of structure modes and implementation modes which can be replaced with each other without changing the essential spirit of the present application. Therefore, the following specific embodiments and drawings are only exemplary description of the technical scheme of the present application, and should not be regarded as the whole or regarded as the limitation or restriction of the technical scheme of the present application.
[0028] As Figure 1As shown, a kind of intermediate medium vaporizer dual-purpose heat transfer comprehensive experimental device, for simulating the real working condition of intermediate medium vaporizer, by working fluid circulation loop 1, heating water circulation loop 3, cooling water circulation loop 2 and data acquisition system composition.
[0029] The following will be combined Figure 2 For working fluid circulation loop 1 is specifically explained.
[0030] Working fluid circulation loop 1 is composed of evaporator 11, plate heat exchanger 12 and condenser 13, the gas generated in evaporator 11 is divided into three outputs and merged into one, which is again divided into three after passing through plate heat exchanger 12, and then enters condenser 13 along the gas pipeline, to ensure uniform distribution of working fluid vapor entering the upper part of condenser 13. The gas working fluid condenses on the condensing pipe and returns to the bottom of the evaporator 11 under the action of gravity, and so on.
[0031] It is worth mentioning that the inner diameter of the barrel of the aforementioned evaporator 11 and condenser 13 is 100 mm, and the length is 600 mm. The total length of the heat exchange pipe in the aforementioned evaporator 11 and condenser 13 is 520 mm, of which the effective heat exchange length is 400 mm. In order to form a seal with the flange, the end of the heat exchange pipe is a smooth pipe with an outer diameter of 25 mm, and is sealed by an O-ring when installed in the evaporator 11 and condenser 13. A sight glass is arranged on the barrel of the aforementioned evaporator 11 and condenser 13 to observe the phase change process, and two front and rear viewports are provided in the middle part. The sight glass is embedded in the aforementioned viewport, and the boiling condition and condensation condition of the working fluid can be observed through the sight glass during the experiment. The evaporator 11 and condenser 13 are made of stainless steel and wrapped with an outer rubber insulation layer to reduce heat dissipation. An exhaust valve is also connected to the condenser 13 for exhaust.
[0032] As Figure 1 As shown, working fluid circulation loop 1 is connected to working fluid storage tank through filling valve, and valve body is arranged between evaporator 11 and plate heat exchanger 12 to control the on-off of the delivery pipeline between evaporator 11 and plate heat exchanger 12. When working fluid needs to be introduced into working fluid circulation loop 1, the filling valve is opened and the aforementioned valve body is closed, and the working fluid enters the evaporator by backflow. A liquid discharge valve is arranged between the aforementioned condenser 13 and evaporator 11. When the working fluid needs to be discharged from working fluid circulation loop 1, the liquid discharge valve is opened, and the working fluid is condensed into liquid state by condenser 13 and can be directly discharged from the liquid discharge valve without entering the evaporator 11.
[0033] The following will be combined Figure 3 For working fluid circulation loop 1 is specifically explained.
[0034] The heating water circulation loop 3 comprises a heating water constant temperature tank 31, a second water pump 32, a mixer 7, an evaporator heat exchange pipe 33 and a plate heat exchanger 12. The heating water constant temperature tank 31 can stabilize the water temperature at the inlet of the pipe of the evaporator 11; the mixer 7 can ensure uniform temperature distribution and increase the measurement accuracy of the temperature; the heating water enters the evaporator heat exchange pipe 33, exchanges heat with the working medium in the evaporator 11 and then returns to the heating water constant temperature tank 31 (i.e. the first loop 34). The heating water circulation has a branch (the second loop 35) to heat the working medium steam in the working medium circulation loop 1 through the plate heat exchanger 12, so that the working medium can be maintained in the steam state and prevent it from condensing and flowing back into the evaporator 11 in advance; the first loop 34 and the second loop 35 are branched at the output end of the second water pump 32.
[0035] The following will be described in detail Figure 4 The cooling water circulation loop 2 will be described in detail.
[0036] The cooling water circulation loop 2 comprises a cooling water constant temperature tank 21, a first water pump 22, a mixer 7 and a condenser heat exchange pipe 23. The cooling water constant temperature tank 21 can stabilize the water temperature at the inlet of the pipe of the condenser 13; the mixer 7 can ensure uniform temperature distribution and increase the measurement accuracy of the temperature; the cooling water enters the condenser heat exchange pipe 23, exchanges heat with the working medium steam in the condenser 13 and then returns to the cooling water constant temperature tank 21.
[0037] The following will be described in detail for the data acquisition system.
[0038] The data acquisition system comprises temperature sensors 6, pressure sensors 5, turbine flow meters 4, mass flow meters 14 and a data acquisition device (not shown). The temperature sensors 6 adopt four-wire platinum resistance, and the platinum resistance is 1 / 3B grade precision. There are 8 temperature measurement points in the two-purpose heat transfer comprehensive experimental device of the medium vaporizer, of which 4 are respectively used to test the inlet temperature of the heating water, the outlet temperature of the heating water, the inlet temperature of the cooling water and the outlet temperature of the cooling water. The other 4 are respectively located at the working medium inlet and outlet of the evaporator 11 and the working medium inlet and outlet of the condenser 13, and are used to test the temperature data of the working medium when entering and leaving the evaporator 11 and the condenser 13. The evaporator 11 and the condenser 13 are respectively provided with a pressure sensor 5 for measuring the working medium pressure in the evaporator 11 and the working medium pressure in the condenser 13. The range of the pressure sensor 5 is 0-2 MPa, and the accuracy is 0.04% FS. Two turbine flow meters 4 are further included to measure the volume flow of the heating water and the cooling water, and the mass flow of the working medium is measured by a Coriolis mass flow meter 14. The data acquisition device is used to integrate the data information of the temperature sensors 6, the pressure sensors 5, the turbine flow meters 4 and the mass flow meters 14 and display and store them, which are applied to the subsequent calculation process.
[0039] The intermediate medium vaporizer (IFV) dual-purpose heat transfer comprehensive experimental device has a pressure range of 0-2 MPa, and can be used for heat transfer experiments of refrigerant working medium such as R134a and working medium such as propane.
[0040] The specific method for performing heat transfer experiments by using the intermediate medium vaporizer (IFV) dual-purpose heat transfer comprehensive experimental device is as follows:
[0041] (1) After the experimental system is built, the whole device needs to be cleaned.
[0042] (2) In order to ensure the reliability of the heat transfer coefficient calculation, the temperature of the eight platinum resistors needs to be checked before the experiment. In order to meet the experimental needs, the temperature checking range of the platinum resistor is determined to be 5-50℃, and the checking is performed at intervals of 3℃. When checking, the eight platinum resistors need to be placed in a constant temperature water bath, and the temperature measurement points need to be at the same position; in order to ensure the reliability of the checking, the contact between the platinum resistors needs to be avoided.
[0043] (3) After the evaporation tube and the condensation tube are installed into the cylinder, the air tightness of the experimental system needs to be tested. It is worth noting that before the heat transfer tube is installed, the test tube needs to be rusted and cleaned. If the heat transfer tube is made of carbon steel, the oxide on the inner and outer surfaces will affect the calculation of the tube wall thermal resistance and the heat transfer coefficient, and the antirust agent needs to be added to the heating water and the cooling water.
[0044] (4) The refrigerant is filled. Keep the vacuum degree, connect the filling valve of the experimental system with the working medium storage tank, pour the working medium storage tank upside down to make the refrigerant outlet downward to facilitate the filling of the refrigerant, and raise the working medium storage tank to make the height of the refrigerant outlet higher than the height of the filling valve of the experimental system. During the filling process, the water circulation can be started to keep the experimental system at a relatively low temperature to facilitate the filling of the refrigerant. When the liquid level of the refrigerant in the evaporation cylinder is higher than the evaporation tube by more than 3 cm, stop filling.
[0045] (5) After the filling is completed, the temperature and pressure characteristics of the working medium circulation loop 1 are tested. If the difference between the saturation temperature measured by the saturation temperature and pressure sensor 5 in the evaporator 11 and the condenser 13 and the shell side pressure is less than 0.2 K, it can be considered that the content of the non-condensable gas is extremely low, and the influence of the non-condensable gas can be ignored. If the requirement is not met, the non-condensable gas needs to be discharged until the requirement is met.
[0046] (6) According to the experimental scheme, adjust the flow rate of the cooling water, the inlet temperature of the cooling water and the heating water. After the working condition reaches a stable state for ten minutes, collect and record each measurement. Each experimental condition needs to be measured for at least sixty groups of data, and then the average value is taken for data processing.
[0047] (7) When the heat transfer experiment of a test tube is completed, the working medium needs to be recovered. After the recovery of the working medium is completed, the heat exchange tube is disassembled.
[0048] The following embodiments are described in detail in conjunction with the application of the intermediate medium vaporizer dual-purpose heat transfer comprehensive experimental device to simulate the actual working condition of the intermediate medium gasifier (IFV), so as to determine the heat transfer coefficient of the intermediate medium gasifier (IFV).
[0049] Example 1
[0050] The three-dimensional finned tube and the sintered porous surface tube are respectively installed in the device as the condensing tube and the evaporating tube, and the experiment is prepared. After the refrigerant charging is completed, the experiment is carried out. The inlet temperature of the heating water and the cooling water, the flow rate of the heating water and the cooling water are adjusted to the specified working condition. After the working condition is stable, the mass flow rate of the refrigerant is read The inlet and outlet temperatures T cwi , T cwo of the cooling water and the inlet and outlet temperatures T hwi , T hwo of the heating water are measured, and the flow rates of the cooling water and the heating water are read. Sixty groups of data are taken for each stable working condition to obtain the average value. The working condition is changed and the experiment is repeated to obtain the detailed heat transfer data of the heat exchange tube.
[0051] For experimental data processing, the sensible heat transfer of the refrigerant can be ignored compared with the latent heat, so the heat transfer can be calculated by the mass flow rate of the working medium: γ wf is the latent heat of vaporization of the working medium.
[0052] In the experiment, it is necessary to ensure that the deviation of the heat balance between the working medium and the cooling water and the heating water is less than 5%. The heat exchange amount of the cooling water is The heat exchange amount of the heating water is In the formula, c p,cw and c p,hw are the specific heat capacities of the cooling water and the heating water at constant pressure, ρ cw and ρ hw are the densities of the cooling water and the heating water, and the property parameters of the cooling water are provided by Nist.
[0053] The total heat transfer coefficient K is In the formula, A o is the heat exchange area of the test tube. For the finned tube, since the outer side of the tube is an irregular structure, it is difficult to calculate the actual heat exchange area, so the outer surface area of the base tube is used instead of calculation. The LMTD of the condensing working condition is the logarithmic mean temperature difference: The LMTD of the boiling working condition is the logarithmic mean temperature difference: In the formula, T sat is the saturation temperature of the working medium.
[0054] The heat transfer coefficient outside the tube is obtained by the heat resistance separation method: where A i is the inner surface area of the tube, R f is the fouling resistance, which can be ignored, and R w is the wall resistance: where λ w is the thermal conductivity of the tube material, d o and d i are the outer diameter and the inner diameter of the base tube, respectively.
[0055] The heat transfer coefficient h i inside the tube by forced convection can be obtained by the modified Wilson plot method, which can be expressed as h i = ch i , where c ip is the enhancement ratio, and h i is obtained by the Gnielinski formula:
[0056] where λ w is the thermal conductivity of water, Re is the Reynolds number of water, and Pr is the Prandtl number of water, and the above parameters are defined by the arithmetic average of the inlet and outlet temperatures of the cooling or heating water, L is the effective length of the finned tube, and Pr w is the Prandtl number of water with the inner wall temperature of the tube as the reference temperature, and the smooth tube resistance coefficient f i is calculated by the Filonenko formula:
[0057] f i = (1.82 lg Re - 1.64) -2
[0058] Therefore, the heat resistance separation method formula can be rewritten as: where,
[0059] It can be seen that when the heat transfer coefficient outside the tube is constant, n is a constant. For a certain test tube, the enhancement ratio c i almost does not change, and m is also a constant.
[0060] According to the heat transfer theory, when the saturation temperature is constant, the same heat transfer amount corresponds to the same heat transfer coefficient outside the tube. By keeping the heat transfer amount and the saturation temperature constant and changing the water flow rate, multiple sets of data are measured. With as the independent variable, as the dependent variable, linear fitting is performed, and the enhancement ratio is obtained according to the slope.
[0061] Since Pr wi is the Prandtl number of water with the inner wall temperature of the tube as the reference temperature, the inner wall temperature T wi of the tube must be obtained.Here, the iterative method is used to calculate:
[0062] First, the arithmetic mean of the inlet and outlet temperatures of the heating or cooling water is set as T wi , h ip and c i are obtained according to the above calculation method, and h i is obtained.
[0063] For condensation, ΔT wi = T wi -(T cwi +T cwo ) / 2.
[0064] For boiling, ΔT wi =(T cwi +T cwo ) / 2-T wi .
[0065] Therefore, the new Pr wi can be obtained according to the obtained T w . This step is repeated until the difference between T wi of two iterations is less than 0.001K.
[0066] According to the above experimental steps and data processing method, the heat transfer of different evaporation tubes and condensation tubes is tested, and after the original data is collected, the data is processed to generate an experimental report.
[0067] The technical scope of the utility model is not only limited to the content in the above description, and those skilled in the art can deform and modify the above embodiment without departing from the technical thought of the utility model, and these deformations and modifications should all belong to the protection scope of the utility model.
