Detailed description of the invention
For making technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear complete description:
Noncontact electrical heating solid-liquid mixing heat-storing device as shown in Figure 1, including: electric heater unit 1, heat storage box 3 and heat-exchanger rig 4, electric heater unit 1 is connected with heat storage box 3 pipeline, heat storage box 3 is connected with heat-exchanger rig 4 pipeline, in use, insulation, heat conduction and arc extinguishing liquid will be loaded with in electric heater unit 1, utilize electric heater unit 1 that this liquid is heated, then the high-temp liquid after heating is entered in heat storage box 3 by pipeline。Being loaded with solid matter and hot body material in heat storage box 3, above-mentioned heated material enters heat storage box 3 and the material in heat storage box 3 and carries out electric heater unit 1 after heat exchange, repeatedly circulates, make the solid in heat storage box 3, temperature of liquid raise under above-mentioned work。Cryogenic substance in heat-exchanger rig 4 is back to heat-exchanger rig 4 after carrying out heat exchange with high temperature material in heat storage box 3 after entering heat storage box 3。Said structure be applied to the insulation in electric heater unit 1, heat conduction and arc extinguishing liquid can as Heat Conduction Material when。
Further, as shown in Figure 2, when the insulation in electric heater unit 1, heat conduction and arc extinguishing liquid and Heat Conduction Material are two kinds of materials, being then provided with heat storage exchanger 2 between electric heater unit 1 and heat storage box 3, heat storage exchanger 2 is connected with electric heater unit 1 and heat storage box 3 pipeline respectively。Liquid after being then heated in electric heater unit 1 enters after liquid internal with it in heat storage exchanger 2 carries out heat exchange and is back to electric heater unit 1。Temperature of liquid in heat storage exchanger 2 enters after heat storage box 3 carries out heat exchange with the material in storage tank 3 after raising and is back to heat storage exchanger 2。
Further, as in figure 2 it is shown, the entrance point of the port of export of described heat storage exchanger 2 and electric heater unit 1 is communicated with water pump I5;The entrance point of the port of export of heat storage box 3 and heat storage exchanger 2 is communicated with water pump II6;The entrance point of the port of export of heat storage box 3 and heat-exchanger rig 4 is communicated with water pump III7。
Further, as in figure 2 it is shown, the entrance point of heat storage box 3 is provided with accommodation chamber I37, the port of export of heat storage box 3 is provided with accommodation chamber II38。It is placed with liquid solution holding in chamber I37 and accommodation chamber II38。
