Abstract
A kind of fuel or gas molten salt furnace, form by fusion tank, circulating pump, heat medium heater, electric control system and conveyance conduit five parts, with fuel oil or natural gas is fuel, with the fused salt is heat carrier, the power-forced liquid phase circulation that utilizes circulating pump to produce, heat energy is flowed to the hot equipment of using, return hydronic single flow heating furnace in the fusion tank then.
Description
Technical field
The invention belongs to a kind of heating facility, is a kind of fuel or gas molten salt furnace specifically.
Background technology
The heat-conducting medium that adopts is to adopt steam and conduction oil at present, in view of with the required temperature of hot equipment, with steam and conduction oil is that the heating facility of medium is difficult to reach and surpasses 300 ℃ high temperature, and common heat medium heater adopts solid fuel (based on coal and wood waste), adopt this fuel combustion heating, not only the efficiency of heating surface is low, but also can cause a large amount of environmental pollutions.
Summary of the invention
The object of the present invention is to provide a kind of is fuel with fuel oil or natural gas, is heat carrier with the fused salt, utilizes circulating pump to force the liquid phase circulation, and heat energy is flowed to the hot equipment of using, and returns the single flow heating furnace that reheats then.The invention solves common heating facility the shortcoming of the high temperature more than 300 ℃ can not be provided, and adopt heating furnace of the present invention to heat, fuel oil or natural gas can be fully burned, reduce air pollution and environmental pollution, can be widely used in industries such as polymerization chemical industry, distillation, plastic, rubber industry, textile printing and dyeing.
In the technical scheme R﹠D process that realizes purpose of the present invention, the repetition test that combines by theory and practice, the present invention can provide 350～600 ℃ high temperature, and adopting fuel oil is the fuel of the comparable common solid saving of fuel 52% of heating fuel, promotes 5% efficiency of combustion; Adopting natural gas is the fuel of the comparable common solid saving of fuel 60% of heating fuel, promotes 5% efficiency of combustion.
The present invention is mainly by fusion tank, circulating pump, heat medium heater, electric control system and conveyance conduit five parts are formed, technical solution of the present invention is achieved in that the present invention adopts fused salt class heat carrier, fused salt adopts potassium nitrate, the mixture of natrium nitrosum and three kinds of inorganic salts of sodium nitrate, mixed proportion is that potassium nitrate is 53%, natrium nitrosum is 40%, sodium nitrate is 7%, the fusing point that adopts the molten salt mixture of this ratio is 142 ℃, the mixed inorganic of powdery is put into fusion tank, by more than the high steam heating tube heat temperature raising to 142 in the fusion tank ℃, the mixed inorganic of powdery enters molten condition, the complete liquefy of powdery mixed inorganic in being heated to groove, start circulating pump, under the pressure power of circulating pump, the mixed inorganic of molten condition is transported to heat-carrier heater and carries out further heat temperature raising, reach 350 ℃ or higher, reach the molten salt after the required temperature, be transported to the hot equipment of using, with with hot equipment sufficient heat exchange, after the release heat, re-circulate to fusion tank and reheat.In the molten salt course of conveying, block pipeline for avoiding inorganic salts Yin Wendu decline cooling to become solid, in pipeline, be blown into hot blast, to replenish the heat-energy losses of fused salt in flow process.Fuel or gas molten salt furnace of the present invention in use need be paid close attention to safety, produce blast for avoiding high-temperature molten salt to contact with organic substance, charge into certain inert gas in the fusion tank domestic demand, and be in barotropic state, and when system's operation stops, whole heat carrier fused salts in the circulatory system will enter in the fusion tank, avoid becoming the solid obstruction pipeline after the fused salt cooling.
Description of drawings
Fig. 1 is a system block diagram of the present invention.
The specific embodiment
The course of work of the present invention is such: the mixed inorganic powdered granule is joined in the fusion tank, under the heating of the high-temperature steam that in fusion tank, feeds, temperature in the fusion tank reaches 142 ℃, mixed inorganic powdered granule fusing liquefy, after being installed in temperature-detecting device in the fusion tank and detecting the fusion temperature that temperature reaches inorganic salts, return a signal of telecommunication and give electric control system, after electric control system receives this signal of telecommunication, send the signal of a startup circulating pump, circulating pump unlatching work, the power that produces in the circulating pump course of work is pressed into the mixed inorganic of the molten condition in the fusion tank in the conveyance conduit, and be delivered to and continue heating in the heat medium heater, heating furnace of the present invention adopts fuel oil or combustion gas to be the burning media, the thermal efficiency of heating is high and flue gas that the back of fully burning produces is also less, and flue gas can be by the smoke stack emission of heat medium heater; By the fused salt after the heat medium heater heating, be delivered to the hot equipment of using by the fused salt conveyance conduit, high-temperature molten salt through with after the abundant heat exchange of hot equipment, temperature decline, and be transferred back in the fusion tank heating once more, thereby finish a cyclic process by the fused salt conveyance conduit.For avoiding fused salt solidifying the obstruction pipeline through temperature decline after the heat exchange, need add companion's thermic devices at the fused salt conveyance conduit, replenish the heat-energy losses of fused salt.
