Abstract
The utility model provides a molten salt heat storage eddy current heater and a molten salt heat storage tank. The molten salt heat storage eddy current heater comprises a non-ferromagnetic material metal plate, an iron plate, a support column, a coil and a coil fixing body. The coil is fixedly arranged below the non-ferromagnetic material metal plate through the coil fixing body. The iron plate is arranged above the non-ferromagnetic material metal plate. The iron plate is fixedly connected with the non-ferromagnetic material metal plate through the support column. Current passes through the coil and produces a magnetic field. When the magnetic field reaches the iron plate through the non-ferromagnetic material metal plate, small eddy current is produced. The iron plate voluntarily heats quickly, thus a salt mixture in the molten salt heat storage tank is heated. The molten salt heat storage eddy current heater and the molten salt heat storage tank have the advantages that the service lives are long; the heating rate of the salt mixture in the heat storage tank is fast; and the heating efficiency is high. In addition, device replacement can be easily realized under the condition that a system does not stop, thus the operation stability is improved, and the service life of the whole system is effectively ensured.

Preferably, an end of described coil fixed body is fixedly connected with described nonferromagnetic material metallic plate, the described coil of other end fixed installation of described coil fixed body.
Preferably, the length of described iron plate is less than the length of described nonferromagnetic material metallic plate.
Preferably, the axis of the longitudinal centre line of the longitudinal centre line of described iron plate, described nonferromagnetic material metallic plate and described coil is positioned at same straight line.
The utility model also provides a kind of fused salt heat storage can, comprises tank body and above-mentioned fused salt heat accumulation eddy current heater more than; Offer more than one through hole in the bottom surface of described tank body, each described fused salt heat accumulation eddy current heater passes described through hole; Described nonferromagnetic material metallic plate and the described through hole of described fused salt heat accumulation eddy current heater are sealedly and fixedly connected, the described iron plate of described fused salt heat accumulation eddy current heater is positioned at the inside of described tank body, and the described coil of described fused salt heat accumulation eddy current heater is positioned at the outside of described tank body.
Preferably, each described through hole is evenly distributed on the bottom surface of described tank body.
The beneficial effects of the utility model are as follows:
The fused salt heat accumulation eddy current heater that the utility model provides and fused salt heat storage can, electric current produces magnetic field by coil, when magnetic field sees through nonferromagnetic material metallic plate arrival iron plate, namely can produce little eddy current, iron plate itself is heating at a high speed voluntarily, thereby heats the saline admixture of fused salt heat storage can inside.Has advantages of long service life and fast and the efficiency of heating surface is high to saline admixture firing rate in heat storage can.

Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated:
As shown in Figure 3, the utility model provides a kind of fused salt heat accumulation eddy current heater, comprising: nonferromagnetic material metallic plate, iron plate, support column, coil and coil fixed body; Described coil is fixedly mounted on the below of described nonferromagnetic material metallic plate by described coil fixed body, described iron plate is arranged on the top of described nonferromagnetic material metallic plate, and described iron plate is fixedly connected with by described support column with described nonferromagnetic material metallic plate.Wherein, an end of coil fixed body is fixedly connected with described nonferromagnetic material metallic plate, the described coil of other end fixed installation of described coil fixed body.In addition, for improving the heating temp of iron plate, the length of iron plate is less than the length of nonferromagnetic material metallic plate.Axis E-the F of the longitudinal centre line A-B of iron plate, the longitudinal centre line C-D of nonferromagnetic material metallic plate and coil can be positioned at same straight line.
As shown in Fig. 1-2, the utility model also provides a kind of fused salt heat storage can, comprises tank body and above-mentioned fused salt heat accumulation eddy current heater more than; Offer more than one through hole in the bottom surface of described tank body, each described through hole preferably is evenly distributed on the bottom surface of tank body.Each described fused salt heat accumulation eddy current heater passes described through hole; Described nonferromagnetic material metallic plate and the described through hole of described fused salt heat accumulation eddy current heater are sealedly and fixedly connected, the described iron plate of described fused salt heat accumulation eddy current heater is positioned at the inside of described tank body, and the described coil of described fused salt heat accumulation eddy current heater is positioned at the outside of described tank body.
The operation principle of the fused salt heat storage can that fused salt heat accumulation eddy current heater is installed that the utility model provides is:
When need to be to the saline admixture heating of fused salt heat storage can inside, electric current produces magnetic field by coil, when magnetic field sees through nonferromagnetic material metallic plate arrival iron plate, namely can produce little eddy current, iron plate itself is heating at a high speed voluntarily, thereby heats the saline admixture of fused salt heat storage can inside.In said process, because the nonferromagnetic material metallic plate can electromagnetic wave absorption, so on the one hand, itself can not generate heat the nonferromagnetic material metallic plate, thereby extended the useful life of nonferromagnetic material metallic plate; On the other hand, electromagnetic wave is fully absorbed by iron plate and generates heat, thereby has improved speed and the efficient of iron plate heating.With respect to the internal electrical heater design that is difficult to change, this kind mode can realize in the situation that stopping system is easily realized equipment replacement.Improve operation stability, effectively guarantee total system useful life.
