Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 and 2, the present invention includes a heating device 1, a heat conducting device 2, a stirling engine 3, and a bracket 4. The heating device comprises a 1-1 invasive heater, a 1-2 control system, a 1-3 conducting wire, a 1-4 outer flange and a flange 2-1 which is connected with the heat conducting device 2 through a 1-5 gasket and a 1-6 bolt. The cylindrical container 2-2 is welded with the flange 2-1, the outer side of the cylindrical container is covered with a ceramic fiber heat insulation layer 2-3, the upper side of the cylindrical container is provided with a hole, an external thread platform feeding hole 2-4 is welded, and the lower side of the cylindrical container is provided with a hole, and an external thread platform discharging hole 2-5 is welded. The right end face of the columnar container 2-2 is closed and is provided with a hole in the center, the sleeve 2-6 is inserted into the cavity by a certain depth through the hole and is welded on the right end face, and the heat-conducting medium 2-7 is contained in the cavity. The spherical valves 2-8 and 2-9 are respectively connected with the external thread feed inlets 2-4 and the external thread discharge outlets 2-5, and when a heat-conducting medium (such as fused salt) needing air isolation heating or a heat-conducting medium (such as heat-conducting oil) needing pressure relief is adopted, the spherical valves 2-8 can be replaced by one-way valves or pressure relief valves.
As shown in FIG. 2, the Stirling engine 3 is divided into a Stirling engine heating end 3-1 and a remaining portion 3-2, and the heating end 3-1 is inserted into the sleeve 2-6 and the gap is filled with heat conductive silica gel 3-3. The support 4 is divided into a left support 4-2, a right support 4-4 and a 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, the working condition of the coolant loss accident is simulated, the heat conduction medium is completely discharged after the experiment is finished, and the chemical corrosion of the device is reduced. The rest of the stirling engine 3-2 is fixed to a platform 4-5 by contact restraint, which is bolted to the right bracket 4-4 and supported by ribs 4-6. In addition, the output end of the Stirling generator is connected with a power measuring device, and thermocouples, which are not shown, are arranged around the sleeves 2-6.
When the device is used for demonstration and verification, the power parameters of the invasive heater 1-1 are set through the control device 1-2, power output is completed within 100ms, after the device is heated for a period of time (the temperature of the heater is not more than 20s and is higher than the melting point of a 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 cylindrical container 2-2 for a long time (such as heat-conducting oil), an experiment can be directly started), after the heat pipe or the heat-conducting medium is filled, the spherical valve 2-8 can be closed (determined visually), and data recording is started (the temperature field distribution in the cylindrical container 2-2 reaches a stable state within about 5min under the geometric parameters of an existing experiment table through simulation calculation).
The heat-conducting medium 2-7 (lead bismuth alloy in the present case) is added after the intrusive heater (1-1) is preheated for 30s, at this time, the temperature of the heater exceeds the melting point of the medium, and the melted heat-conducting medium flows to the right side of the cylindrical container 2-2 due to the lower viscosity of the medium. Due to the excellent heat-conducting property of the heat-conducting 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 parameters in real time, and demonstration verification of different working conditions is realized by combining the setting parameters of the control system.
In particular, a stirling cycle reactor demonstration and verification device made in accordance with the present invention is disclosed. The device adopts a heating device 1 with the power range of 1-8kW, the size of a heating rod of an invasive heater 1-1 is phi 10x250mm, and 4 heating rods are uniformly distributed on the circumference of phi 40. The cylindrical container 2-2 is made of a 304 stainless steel pipe 300mm long DN80, the ceramic fiber heat-insulating layer 2-3 is 20mm thick, the external thread platform 2-4 and 2-5 inches in caliber are matched with DN40 high-temperature ball valves 2-8 and 2-9. 2-6 of the sleeve is 19mm long and 2mm thick, 3-1 of the heating end of the Stirling engine is 39mm long, and 3-3 of the heat-conducting silica gel has the heat conductivity of 2W/(mK). The size of the bracket is not directly related to the demonstration verification target of the system core, and the detailed description is omitted here.
With reference to fig. 3 (cylindrical vessel 2-2 axis temperature profile), when the heater rod temperature reached 873K, the sleeve steady state temperature reached 790K (about 520 c), thereby proving 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 geometric dimensions of the cylindrical container 2-2, the heat transfer medium 2-7, etc. are not limited to those listed in the above examples, and can be adjusted according to the verification accuracy and the conceptual design.
For example, some conceptual designs optionally include a coolant circulation loop, and when such conceptual designs are demonstrated, mating external threaded pipes and circulation pumps may be connected to the other side of the globe valves 2-8 and 2-9.
For example, the present invention alternatively employs a mass-produced stirling engine as the modular component 3, based on the initial design of low cost and the current state of research of the stirling engine in domestic space. If special requirements are required for demonstration and verification precision, a Stirling engine prototype selected by concept design can be selected for demonstration and verification.
For example, alternatively, fig. 3 shows only the temperature distribution at the axis of the cylindrical vessel 2-2 in steady state operation under the set parameters, and the temperature distribution in the remaining operating states (such as transient temperature distribution at start/stop and gradual absence of coolant) may be set to the corresponding initial conditions for numerical calculation.
For example, the present invention may also optionally employ a heat conductive oil, a molten salt, a heat pipe, or the like having a heat conductive capability as a heat conductive medium. According to the existing experimental data, the maximum heating temperature when using heat conduction oil should not exceed 220 ℃, 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.
