Abstract
The utility model provides a rapid fused salt heating and melting device, which aims at solving the problem that a special rapid smelting device for testing the performance of fused salt is in shortage at present, and relates to a heating device. The rapid fused salt heating and melting device comprises a stainless steel storage tank, wherein the outer side of the stainless steel storage tank is provided with heat insulation cotton for heat insulation, a resistance wire heating layer is arranged between the outer side of the stainless steel storage tank and the heat insulation cotton, the resistance wire heating layer is formed by winding a heating resistance wire on the outer wall of the stainless storage tank, and the insulation of the heating resistance wire is realized by sleeving porcelain beads on the nickel-chromium resistance wire. The rapid fused salt heating and melting device is simple in structure and can be used for testing the high-temperature fused salt, the high-temperature fused salt can be rapidly heated and molten, and the insulation effect of a tank body for the molten high-temperature fused salt is good.
Description
Technical field:
The utility model relates to a kind of heating arrangement, relates in particular to a kind of fused salt Fast Heating melting appartus.
Background technology:
In the fast development of solar energy optical-thermal field, in the exploitation of photo-thermal power station, fused salt has become the important leverage that long-time stable electric generation is realized in current photo-thermal power station as a kind of heat transfer, heat accumulation actuating medium of better performances at present.
In the exploitation of photo-thermal power station, fused salt has become the important leverage that long-time stable electric generation is realized in current photo-thermal power station as a kind of heat transfer, heat accumulation actuating medium of better performances.Traditional fused salt that application arranged in the project of a plurality of actual power stations is generally mixed by 60% sodium nitrate and 40% potassium nitrate, and this fused salt has all been adopted in the U.S. and Hispanic a plurality of CSP power station.Facts have proved that the configuration heat reservoir can make photo-thermal power generation and unsettled photovoltaic and wind-powered electricity generation contend with.Such configuration also makes the CSP power station can realize 24 hours continued powers and the Height Adjustable characteristic of output power, the electrical production mode of its capable and traditional coal electricity, fuel gas generation, nuclear power is compared favourably, possessed the potentiality as shoring of foundation power supply and the competition of traditional thermal power plant.
All the time, the heat-storage medium that more can be applicable to photo-thermal power generation is also being continued research and development, but so far, does not also have a kind of can comparing favourably with fused salt.The performance test work of some high-temperature molten salts need be melted high-temperature molten salt fast now, lacks a kind of specialized equipment that high-temperature molten salt can be melted fast at present, to satisfy high-temperature molten salt performance test requirements of one's work.
The utility model content:
Technical problem to be solved in the utility model is to overcome the defective of prior art, and a kind of fused salt Fast Heating melting appartus is provided, to be used for carrying out the test job of high-temperature molten salt aspect.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A kind of fused salt Fast Heating melting appartus, it is characterized in that: comprise a stainless steel storage tank, the stainless steel storage tank outside adds the heat-preservation cotton insulation, be provided with the resistance wire zone of heating between the described stainless steel storage tank outside and the heat-preservation cotton, described resistance wire zone of heating is to be wrapped on the stainless steel storage tank outer wall by resistive heater to constitute, and described resistive heater is to be enclosed within the insulation that realizes the resistance wire outside on the nickel-chromium resistance wire with porcelain bead.
Described resistance wire zone of heating is connected with temperature control system.
Described temperature control system is the temperature of gathering the stainless steel storage tank outside by thermopair, adjusts the electric current of resistive heater again by thermometric instrument control controllable silicon, realizes the control of fused salt fusing heating power.
Fused salt fusing heating is the process that realizes the solid-state fusing of fused salt normal temperature and be heated to 500 ℃ in a stainless steel storage tank.
A kind of fused salt Fast Heating melting appartus that the utility model provides, this apparatus structure is simple, can be used for carrying out the test job of high-temperature molten salt aspect, can be with the fusing of high-temperature molten salt Fast Heating, tank body is to the high-temperature molten salt high insulating effect after melting.
