Specific embodiment
Below in conjunction with the drawings and specific embodiments to the utility model proposes a kind of electric heating fused salt heating plant make into
One step is described in detail.According to following explanation and claims, will be become apparent from feature the advantages of the utility model.It should be noted
It is that attached drawing is all made of very simplified form and using non-accurate ratio, only to facilitate, lucidly aid in illustrating this reality
With the purpose of new embodiment.
Embodiment one
The utility model provides a kind of electric heating fused salt heating plant, and structure is as shown in Figure 1.The electric heating fused salt
Heating plant includes container 1 and cavity 2.Heat exchanger tube 3 is equipped with inside the container 1；It is inserted with heating element 4 in the heat exchanger tube 3,
The heating element 4 can be high voltage heating element, ceiling voltage 10kV；Preferably, the inside of the container 1 is equipped with branch
Support ring 5, for fixing the heat exchanger tube 3, the bottom of the container 1 is equipped with port 10, for flowing out the fluid media (medium) after heating.
The cavity 2 is located at the top of the container 1 and communicates with the container 1.As shown in Fig. 2, equipped with flow point in the cavity 2
Orchestration 6, and be connected to the import of fluid 7.Please continue to refer to Fig. 2, fused-salt medium enters in the cavity 2 from import 7, passes through institute
It states flow distributor 6 to be assigned in each heat exchanger tube, be flowed through by the gap high speed between the heat exchanger tube 3 and its heating element 4,
Since this gap makes fluid velocity higher, the power density of the heating element 4 can also be very high, and general power density can
Reach 50-100W/cm2, can effectively save integrally-built volume.
Specifically, supported at three point is used between the heating element 4 and the heat exchanger tube 3, referring to Fig. 3, making the electric heating
Element 4 is in the middle position of the heat exchanger tube 3.Wherein, the heating element 4 is U-shaped heating element, is passed through in U-shaped elbow
