Detailed Description
The invention is described in further detail below with reference to the drawings and the detailed description.
As shown in fig. 1 and 2, the present invention includes a heating device 1, a heat conduction device 2, a stirling engine 3, and a bracket 4. The heating device comprises a 1-1 invasive heater, a 1-2 control system, 1-3 wires, a 1-4 outer flange, and a flange 2-1 connected with the heat conduction device 2 through a 1-5 gasket and a 1-6 bolt. The columnar container 2-2 is welded with the flange 2-1, the outer side is covered with the ceramic fiber heat insulation layer 2-3, the upper side is provided with holes, the external thread platform feed inlet 2-4 is welded, and the lower side is provided with holes, the external thread platform discharge outlet 2-5 is welded. The right end face of the columnar container 2-2 is closed, a hole is formed in the center of the columnar container, the sleeve 2-6 is inserted into the cavity through the hole to a certain depth and welded to the right end face, and the heat conducting medium 2-7 is contained in the cavity. The ball valve 2-8 and the ball valve 2-9 are respectively connected with the external thread feed inlet 2-4 and the external thread discharge outlet 2-5, and when a heat conducting medium (such as molten salt) needing to isolate air heating or a heat conducting medium (such as heat conducting oil) needing to release pressure is adopted, the ball valve 2-8 can be replaced by a one-way valve or a pressure release valve.
As shown in fig. 2, the stirling engine 3 is divided into a heating end 3-1 of the stirling engine and the remaining part 3-2, the heating end 3-1 of which is inserted into the sleeve 2-6 and the gap is filled with heat conductive silica gel 3-3. The bracket 4 is divided into a left bracket 4-2, a right bracket 4-4 and a cross beam 4-3. The cushion block 4-1 is connected to the cross beam 4-3 through a bolt, the left end of the heat conduction device 2 is lifted, the heat conduction medium 2-7 is conveniently discharged from the discharge port 2-5, so that the accident condition of coolant deficiency is simulated, the heat conduction medium is discharged after the experiment is finished, and the chemical corrosion of the device is reduced. The remainder of the Stirling engine 3-2 is secured by contact constraint to a platform 4-5 which is bolted to the right bracket 4-4 and supported by the ribs 4-6. In addition, the output of the Stirling generator is connected to a power measuring device, and thermocouples, not shown here, are arranged around the sleeves 2-6.
When the invention is used for demonstration verification, the power parameters of the invasive heater 1-1 are set by the control device 1-2, the power output is completed within 100ms, after heating for a period of time (not more than 20s, the temperature of the heater is higher than the melting point of the heat conducting medium), the heat conducting medium 2-7 is added from the feed port 2-5 (if a heat pipe or the heat conducting medium can be stored in the columnar container 2-2 for a long time (such as heat conducting oil is used), the experiment can be directly started), after the heat conducting medium is filled (can be confirmed visually), the spherical valve 2-8 is closed, and data recording is started (the temperature field distribution in the columnar container 2-2 reaches a steady state after simulation calculation under the geometric parameters of the existing experiment table for about 5 min).
The heat conducting medium 2-7 (here, lead bismuth alloy) is added after the invasive heater (1-1) is preheated for 30s, at which time the heater temperature exceeds the medium melting point, and the melted heat conducting medium flows to the right side of the cylindrical container 2-2 due to the lower medium viscosity. Due to the excellent heat conductive properties of the heat conductive medium, a large amount of heating power can be conducted to the stirling engine 3. After the heating end 3-1 of the Stirling engine is heated, gas in the engine is heated and expanded, and heat energy is converted into electric energy through a thermodynamic cycle (Stirling cycle) and a generator. In the conversion process, the thermocouple measures the temperature of the inner wall of the sleeve in real time, the universal meter measures the power generation parameter in real time, and the demonstration verification of different working conditions is realized by combining the setting parameters of the control system.
In particular, a stirling cycle reactor demonstration verification device made in accordance with the present invention is pointed out herein. The device adopts a heating device 1 with the power range of 1-8kW, the size of a heating rod of the invasive heater 1-1 is phi 10x250mm, and 4 heating rods are uniformly distributed on the circumference of phi 40. The columnar container 2-2 is made of a 304 stainless steel tube with the length DN80 of 300mm, the thickness of the ceramic fiber heat insulation layer 2-3 is 20mm, the caliber of the external thread platforms 2-4 and 2-5 is 1.5 inches, and the high-temperature spherical valves 2-8 and 2-9 of DN40 are matched. The sleeve 2-6 is 19mm long and 2mm thick, the heating end of the Stirling engine is 3-1 mm long, and the heat conductivity of the heat conducting silica gel 3-3 is 2W/(mK). The size of the support is not directly related to the verification target of the system core demonstration, and the description is omitted here.
Referring to fig. 3 (cylindrical vessel 2-2 axis temperature distribution), when the heating rod temperature reached 873K, the sleeve steady state temperature reached 790K (about 520 ℃), thereby demonstrating the rationality and advancement of the present invention by numerical calculations.
It should be understood that the heat transfer medium 2-7, the power parameters of the invasive heater 1-1, the geometry of the columnar container 2-2, the heat transfer medium 2-7, etc. are not limited to those exemplified in the above examples, and the above parameters may be adjusted according to the verification accuracy and conceptual design.
For example, some conceptual designs may optionally include coolant circulation loops, and when such conceptual designs are demonstrated, mating externally threaded tubing and circulation pumps may be connected to the other side of ball valves 2-8 and 2-9.
For example, the present invention may alternatively employ a mass-produced Stirling engine as the modular part 3 based on the original purpose of inexpensive design and the current state of the art of domestic space Stirling engines. If special requirements are required on the accuracy of demonstration verification, the Stirling engine prototype selected by the conceptual design can be selected for demonstration verification.
For example, alternatively, fig. 3 only shows the temperature distribution at the axis of the columnar vessel 2-2 at the time of steady-state operation at the set parameters, and the temperature distribution of the remaining operation states (such as the transient temperature distribution of start-up/shut-down and the time when the coolant is gradually lost) may be set to the corresponding initial conditions for numerical calculation.
For example, the present invention may alternatively employ a substance having heat conductive ability such as heat conductive oil, molten salt, heat pipe, or the like as the heat conductive medium. According to the existing experimental data, the highest heating temperature should not exceed 220 ℃ when using heat conduction oil, forced convection equipment (such as a stirrer) or a flow loop needs to be arranged in the columnar container 2-2 when using molten salt as a heat conduction medium, and a positioning grid needs to be arranged in the columnar container 2-2 when using a heat pipe, so that the structural stability is improved.
In summary, the invention provides a Stirling cycle reactor demonstration verification device, which comprises four parts, namely a bracket, a heating device, a heat conduction device and a Stirling engine. The heating device and the heat conduction device are connected through a welding flange and a bolt, the invasive heater and the heat conduction medium are contained in the cavity of the heat conduction device, the upper side surface and the lower side surface of the heat conduction device are respectively provided with holes and welded with a threaded platform, and the spherical valve is installed. The heating end of the Stirling engine realizes heat conduction through the sleeve, and heat conduction silica gel is filled at the contact part of the heating end and the sleeve to reduce heat resistance. The heating device, the heat conduction device and the Stirling engine are all arranged on the support, and the left end face of the heat conduction device is lifted through the cushion block, so that heat conduction medium can flow and be discharged conveniently.
The invention regulates and controls the power parameters of the invasive heater through the control system, completes power regulation and output within 100ms, and realizes the redistribution of an internal temperature field (using lead bismuth alloy) within a few minutes, thereby simulating different reactor core temperatures and realizing demonstration verification of the reactor working condition under the working conditions of starting, stable operation, shutdown and partial accidents.
For the Stirling engine, the invention adopts the model of the Stirling engine produced in batch based on the principle of low price, thereby being convenient for the production and the assembly of experimental devices. For high-precision verification requirements, part of modules (such as Stirling engines, sleeves and the like) can be replaced by special prototype parts, so that the rationality of the overall design of the reactor can be verified on the one hand, and the rationality of the special Stirling engines can be verified on the other hand.
In the design of the invention, a large number of detachable bolt connection and modularized designs are used, so that the invention has great flexibility, and demonstration verification of different conceptual designs can be realized.
For the heat conduction portion, based on the experimental and simulation results conducted so far, it is preferable to use a lead bismuth alloy as the heat conduction medium. For part of special designs, the heat conducting medium can be flexibly replaced by corresponding substances, or the feed inlet and the discharge outlet are connected with a pipeline to manufacture a gaseous/liquid working medium circulation loop, so that the application range of the invention is enlarged.
Through numerical calculation, the heat transfer efficiency of the invention is higher, and the rationality and the advancement of the design are verified. The invention can be used as a demonstration verification device of a reactor type based on Stirling cycle, and has the advantages of simple body design, low price, accurate and convenient data acquisition and wide research range.
