The specific embodiment:
Below in conjunction with drawings and Examples the utility model is further described.
Referring to accompanying drawing, the utility model comprises heating system, pressure self-adjusting joint system and fuel control system 19.The body of heater 1 that comprises sealing in the said heating system, being installed in having circulation catch fire coil pipe 2, the tube 18 of heated medium, the heat medium 16 of smoke pipe 17 and certain flow in the body of heater 1.Said pressure self-adjusting joint system comprises collection box 11, check valve 7, injector mixer 8, infusion pump 9 and pressure controller 10; Described collection box 11 is provided with outside the body of heater 1, and its side is provided with liquid-level switch 15, and collection box 11 can be connected with body of heater 1 by liquid-level switch 15; Also be equipped with the fuel coil pipe in the collection box 11; Said check valve 7 and injector mixer 8 also are set in turn between body of heater 1 and the collection box 11; Also be provided with pressure controller 10 on body of heater 1, said pressure controller 10 is connected with infusion pump 9, and described infusion pump 9 one ends are connected with injector mixer 8, and the other end is connected with collection box 11, and the top of described collection box 11 is provided with atmospheric valve 13.Also be provided with unidirectional relief valve 14 between said body of heater 1 and the collection box 11.
On body of heater 1, also be provided with burst disk 6, thermometer 3, conventional accessory such as vent valve 4 and Pressure gauge 5.On collection box 11, also be provided with burst disk 12.
When using the utility model, heating furnace can adopt the hot type method to get rid of furnace air before work, realized the vacuum work state, and heat medium produces phase-change heat-exchange, and is energy-efficient.After heating up, heating furnace opens vent valve 4 deaerations.Close vent valve after air has been arranged and enter the heating in vacuum state.After the heating furnace work, fire tube 18 and smoke pipe 17 are passed to liquid medium 16 to the heat that burner produced in the fuel control system 19.Change gaseous state into after liquid medium 16 is heated, run into the coil pipe 2 of cold conditions after, heat is passed to coil pipe 2, and makes and self be condensed into liquid state.In this phase transition process, discharged the heat of transformation to coil pipe 2 again.The effect of heat transfer is improved greatly.Because produce phase transformation, volume sharply shrinks, and has formed negative pressure thereby make in the body of heater 1.Continuous in the process of liquid medium 16 heat supplies and coil pipe 2 heat absorptions at fire tube 18, evaporation and condensation reach relative equilibrium, keep metastable negative pressure in the body of heater 1.
When evaporation capacity during greater than condensation number, furnace pressure raises and forms malleation.When pressure reached pressure-fired, pressure controller 10 was opened infusion pump 9, extracted unnecessary gaseous medium out by the check valve 7 that connects in the injector mixer 8.In the process that extracts, from the cold conditions liquid in the collection box 11 with from the mixing mutually in injector mixer and pipeline of the hot gas in the stove, and carry out thermal energy exchange and make most of gaseous medium be condensed into liquid state, sent back to collection box 11 at last together.
When said collection box pressure reached certain pressure-fired, the atmospheric valve 13 that is installed in its top was opened.Discharge micro-unnecessary gas, keep collection box pressure.
When the liquid in the said collection box reached certain liquid level, liquid-level switch 15 was opened, and liquid is put into stove, has reclaimed thermal medium.
Top overall process has accurately been regulated negative pressure in the stove, has also absorbed unnecessary heat.
Thermal medium in the collection box also is used for the ducted fuel gas of pre-heating fuel, makes a small amount of liquid hydrocarbon volatilization in the fuel gas, improves efficiency of combustion, has prevented from that liquid fuel from entering to cause flame-outly, and makes burning more stable.
When non-transformer, this device also can be kept negative pressure in the stove preferably automatically.When furnace pressure reached pressure-fired, the unidirectional relief valve 14 that is installed between body of heater and collection box was opened, and unnecessary gas is discharged by the liquid in the collection box 11 in the body of heater 1, liquid absorbing member heat energy.
The process of above-mentioned pressure self-adjusting joint can only realize that under the evaporation operating mode roughly suitable with condensation controlling furnace temp and pressure at first is to realize by fuel control system 19, and its meticulous adjusting realizes by top said pressure self-adjusting joint system.
