Description

The vacuum evaporation heating plant

One, technical field the utility model provides thermal technology field heating plant, specifically vacuum evaporation heating plant.

Two, the background technology steam boiler produces vapours, is communicated with radiator by pipeline to constitute heating plant again.The steam of this heating plant is realized by steam boiler.Usually in steam boiler, inject the water of handling through softening, through fuel or the heating of other energy, make the water vapor evaporation, by the decalescence of water heat is brought in the radiator, water vapour is lowered the temperature to liquefy in radiator and is back in the steam boiler again, recirculation evaporation work.In this heating plant, be in steam boiler or the radiator all for malleation, thereby, in the apparatus system specification requirement higher, security is relatively poor.And the boiler preheating time is long, and the water in the boiler does not evaporate, and fin just can not be worked, and has retardance.When stopping heat supply, the water temperature in the boiler is higher, and it is more to store heat, and also causes waste.Owing to contain air in certain amount and mineral matter in the water, the device inwall there is a certain amount of corrosion again.This heating plant is less economical in little application scenario.Because there is the above-mentioned shortcoming that is difficult to overcome, thereby, seldom produce now, install and use.

Three, summary of the invention the utility model provides a kind of vacuum evaporation heating plant.Concrete scheme is, on evaporimeter, establish heater, can be electricity, coal, combustion gas equal energy source heater, in parallel or connect to several radiators upper end by pipeline on evaporimeter with one, and draw return duct in the radiator lower end and be connected with base of evaporator, formation work loop vacuumizes in the system, and injects the phase transformation conductive liquid in evaporimeter.

The heating plant that adopts the utility model scheme to make has following advantage:

1, security is good, is in vacuum state because evaporation reaches in the pipeline that links to each other with radiator, and after the evaporation of phase transformation conduction hydrothermal solution, its pressure increases less, is difficult for generation explosion and leakage.

2, heat conduction efficiency height, because the phase transformation conductive liquid is in vacuum state, thereby after being heated, under lower temperature, conductive liquid will reach boiling point and evaporate diffusion, arrives radiator and carries out heat supply work.Reaction speed is fast, and thermal starting is fast, and heat supply is even, and heat stagnation is little.

3, device inside is not perishable because phase transformation conduction is the liquid object through specially treated and proportioning, removed mineralising matter wherein and dissolve within it air.Thereby, be difficult for that metal in installing is produced corrosion and make the heating plant long service life.

Because the utility model device has as above major advantage, thereby, can be used as the heating of building, fields such as drying article and oil, chemical industry, agricultural are as heating plant.

Four, description of drawings

Fig. 1 is the utility model apparatus structure schematic diagram

Among Fig. 1,1 is evaporimeter, in evaporimeter 1 bottom or sidepiece heater 5 is installed, in the evaporimeter upper end evaporation conduit 2 is installed, and be connected with one to some groups radiators 3, radiator is provided with heat-dissipating fin 3a, is connected with evaporimeter 1 bottom by return duct 4 in the radiator bottom.A certain amount of phase transformation conductive liquid 1a is housed in evaporimeter.

Five, the specific embodiment

With the indoor heating device is that example is illustrated

Make the evaporimeter 1 of cavity type with metal, and be installed in coal stove or the heaters such as electric furnace, gas furnace 5, with metal tube make the evaporation conduit 2, and with evaporimeter 1 upper end and radiator 3 upper ends between be communicated with installation.Radiator 3 can be cavate or patterns such as sheet string type, fin tubular type.Also make return duct 4, and be communicated between radiator 3 and evaporimeter 1 bottom with metal tube.In evaporimeter 1, inject a certain amount of phase transformation conductive liquid 1a.Vacuumize in evaporimeter and radiator and the connecting line.Radiator can be one group or some groups, adopts the mode of serial or parallel connection to connect.

The explanation of the utility model course of work

When thermal source acts on the chamber wall of evaporimeter 1, be subjected to heat conducting effect, heat is conducted to the phase transformation conductive liquid, the phase transformation conductive liquid is heated up, when reaching uniform temperature and be boiling point, just beginning by liquid phase transition is vapour phase, density reduces, and proportion reduces, and is subjected to heat effect to evaporate diffusion by evaporating conduit 2 in radiator, when contacting with radiator 3 inwalls, the dispelled the heat heat conduction heat-absorbing action of wall conducts heat to heat radiation wall and heat sink fins, realizes the conduction of extraneous air heat, mode with conduction and heat radiation and thermal convection current heats room air, realizes indoor intensification.Behind the certain heat of phase transformation conductive liquid vapor evolution in the radiator, just change liquid state into from steam state, increase in density, proportion increases, and gravitate is collected at the radiator bottom.Because the phase transformation conductive liquid in the evaporimeter 1 constantly evaporates, produce negative pressure again in its bottom, be back to the bottom of evaporimeter 1 to making the low temperature phase change conductive liquid that is stored in the radiator be subjected to the effect of self gravitation and evaporimeter negative pressure by return duct 4, again to mend fair phase transformation conductive liquid.So periodic duty has realized the phase transformation conduction and circulation of heat, thereby has realized the room air or the heating purposes of other gas, liquid, solid attitude material.
