Embodiment 1
[0032]In this embodiment, the structure of the phase change regenerative solar heater is as follows figure 1 , 2 As shown, it consists of a phase-change thermal storage heater 1, a solar thermal collector, and a bracket 4 supporting the phase-change thermal storage heater and the solar thermal collector. The structure of the phase change thermal storage heater 1 is as follows image 3 As shown in the figure, it includes a thermal insulation box, a heat transfer pipe 8, a heat exchange coil 7 and a phase change heat storage material; the thermal insulation box is made of a cylindrical box 5-1 made of carbon steel and a polyurethane thermal insulation layer covered by the outer wall of the box 5-2, the wall of the box is provided with a hole for pouring paraffin and rosin mixture, and is equipped with a hole plug 5-3; the heat pipe 8 is made of stainless steel 304, and is installed in the cylindrical box 5 -1 The lower part of the inner cavity; the heat exchange coil 7 is made...
Embodiment 2
[0034] In this embodiment, the system for producing biodiesel using solar energy is as follows Figure 4 As shown, it includes the phase-change regenerative solar heater 11 , the oil storage container 13 , the biodiesel equipment 15 , the circulation pump 12 , the control device 14 and the solar power source 16 described in Embodiment 1.
[0035] The phase-change regenerative solar heater 11 is used to heat the grease raw material; the oil storage container 13 is provided with two oil inlets and two oil outlets, and is equipped with a liquid level gauge and a thermometer. The oil port is used to add unheated grease raw material, a first solenoid valve 131 is installed at the first oil inlet port, and the second oil outlet port is used to output the grease raw material heated to meet the temperature requirements. A second solenoid valve 132 is installed at the place, the second solenoid valve is connected to the oil inlet of the biodiesel equipment through a pipe fitting, and i...
Embodiment 3
[0038] In this example, the system for producing biodiesel using solar energy described in Example 2 is used to produce biodiesel, the oil and fat raw material is Jatropha curcas oil, and the catalyst is calcium oxide. The preparation method of the catalyst is as follows: using calcium hydroxide as a raw material, the calcium hydroxide is placed in a muffle furnace, calcined at normal pressure and 800 DEG C for 2 hours, then cooled to room temperature with the furnace, taken out, and ground with an 80-mesh sieve. The calcium oxide powder obtained by screening is the catalyst.
[0039] In the present embodiment, the operation steps of producing biodiesel are as follows:
[0040] ①Turn on the solar power supply 16 and the control device 14, under the control of the control device, add rated Jatropha curcas oil into the oil storage container 13, and transport the oil through the circulating pump 12, so that the oil and fat raw materials are stored in the phase-change regenerative...
