Abstract
The invention improves the technology of current experimental molten salt furnace heating systems, and effectively prevents the damage of electric heating elements. The specific technical scheme is as follows: the heating system of the molten salt heating furnace comprises a base, an insulating material, an inner cavity of the heating furnace and a shell, wherein the inner cavity of the heating furnace is made of a thickened high-temperature resistant steel plate, and at least one group of electric heaters are arranged on the exterior wall of the inner cavity of the heating furnace; the electric heaters are electric heating pipes which are fixedly coiled on the exterior wall of the inner cavity of the heating furnace through bolts and steel belts, and electric heating wires are arranged inside the electric heating pipes; the heights of the electric heating pipes are lower than the main body of the inner cavity of the heating furnace, and the two ends of the electric heating pipes extend outside the shell to be connected with exterior wires; the insulating material is filled between the electric heater and the shell of the heating furnace; the shell of the heating furnace is a stainless steel product. The heating system provided by the invention has the beneficial effects that the heat transmission efficiency is improved, the heat loss is reduced and the heating efficiency is guaranteed, thus the economic benefit is good.
Description
Technical field
The present invention relates to chemical catalyst experimental provision technical field, particularly a kind of heating system of fused salt heating furnace.
Background technology
At present, wrap up one deck asbestos cloth at the outer surface of molten salt furnace inner chamber carrying out the mode of heating that in the reaction of laboratory catalytic agent lab scale, fused salt heating furnace used adopts, in order to separate electric furnace heating wire and body of heater, to reach the object of insulation, again electrothermal furnace silk is put on the magnet ring Hou ， Chan that prevents line from the leaking electricity outside around asbestos layer.Adopt the shortcoming of this mode of heating as follows:
1, when fused salt has seepage time, the easily company's of generation electrical short and incinerator silk,
2, in use, due to the effect of expanding with heat and contract with cold, cause the downward landing of stove silk, thus make lower portion of furnace body stove silk density excessive, and top does not have stove silk can not normal heating, cause thus in the process of fused salt melting, due to the too fast and fused salt Flashmelt of bottom of bottom heating, volumetric expansion, and the fused salt on top is still solid, and in stove, produce high pressure, fused salt is upwards sprayed and hurts sb.'s feelings or damage other article.
Summary of the invention
For the problems referred to above, the present invention has carried out technological improvement to existing laboratory molten salt furnace heating system, effectively prevent the damage of electrical heating elements, and its concrete technical scheme is as follows:
A heating system for fused salt heating furnace, comprises pedestal, insulation material, and heating furnace inner chamber and shell, is characterized in that: described heating furnace inner chamber is made by thickening high temperature resistant steel plate, and in heating furnace, cavity outer wall is provided with at least one group of electric heater; Described electric heater is the electric heating tube being coiled in cavity outer wall in heating furnace fixed with screw and steel band, and the inside of described electric heating tube is provided with electrical heating wire; The height of described electric heating tube is lower than cavity main body in heating furnace, and the two ends of electric heating tube are stretched out fused salt oven enclosure and connected external cable; Described filled thermal insulation materials is between electric heater and oven enclosure; Described oven enclosure is stainless steel products.
Preferably, the two ends of described electrical heating wire are connected with electric wire by terminal.
Preferably, described heating furnace chamber exit diameter is greater than heating furnace inner chamber main diameter.
Preferably, asbestos fibre goods selected by described insulation material.
Beneficial effect of the present invention is:
1, set up heating tube in electrical heating wire outside, eliminating is short-circuited because of molten salt leakage burns the defect of electrical heating wire;
2, with screw and steel band, the electric heating tube of coiling is fixed on interior cavity outer wall, thus directly heats molten salt furnace, improve heat transfer efficiency, economize energy;
3, be added with insulation at the skin insulation material of heater, to reduce the loss of heat, ensure heating effect, there is good economic benefit.
Accompanying drawing explanation
Accompanying drawing 1 is the heating system structural representation of a kind of fused salt heating furnace of the present invention, in figure:
1. electric heating tube, 2. oven enclosure, cavity main body 3., 4. chamber exit, 5. screw, 6. steel band, 7. electrical heating wire.
Detailed description of the invention
Below, in conjunction with the accompanying drawings and embodiments the heating system of a kind of fused salt heating furnace of the present invention is illustrated further.
As shown in drawings, a kind of heating system of fused salt heating furnace, comprises pedestal, insulation material, heating furnace inner chamber and oven enclosure 2, is characterized in that: described heating furnace inner chamber is made by thickening high temperature resistant steel plate, and in heating furnace, cavity outer wall is provided with at least one group of electric heater; Described electric heater is the electric heating tube 1 being coiled in cavity outer wall in heating furnace fixed with screw 5 and steel band 6, and the inside of described electric heating tube 1 is provided with electrical heating wire 7; The height of described electric heating tube 1 is lower than cavity main body in heating furnace 3, and the two ends of electric heating tube 1 are stretched out fused salt oven enclosure 2 and connected external cable; Described filled thermal insulation materials is between electric heater and oven enclosure 2; Described oven enclosure 2 is stainless steel products.
Preferably, the two ends of described electrical heating wire 7 are connected with electric wire by terminal.
Preferably, described heating furnace chamber exit 4 diameter is greater than cavity main body 3 diameter in heating furnace.
Preferably, asbestos fibre goods selected by described insulation material.
During use, switch on power, electrical heating wire 7 is started working, electric heating tube 1 by heat transfer through fused salt in interior cavity main body 3 heating chamber, the electric heating tube 1 of coiling is fixed on interior cavity outer wall, sliding phenomenon can not occur, interior cavity main body 3 is heated evenly, and there will not be because local heat is too fast and the phenomenon of splash occurs.The molten salt furnace heating system of design of the present invention improves heat transfer efficiency, reduces the loss of heat, ensures heating effect, has good economic benefit.
