The favor of consumers in general.
Combustion gas vacuum boiler belongs to country's freed-from-inspection product, and along with the development of Gas Industry, combustion gas vacuum boiler also obtains
Development rapidly, but the developing history of combustion gas vacuum boiler is short, design experiences is not enough, present stage still has a lot of problem suddenly to wait to solve
Certainly: a vacuum boiler of present stage can only heat a kind of fluid, greatly reduces the popularization and application of vacuum boiler；Market now
On three-pass boiler have tube sheet cracking, radiation loss big and the problem such as the thermal efficiency is low.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of safe and efficient, a plurality of fluids and added simultaneously
The novel bifilar stream central flame flame vacuum boiler that heat, compact conformation, floor space are little, fuel can use natural gas and liquefied petroleum
Gas.
The technical solution adopted in the present invention is: novel bifilar stream central flame flame vacuum boiler, including burner, housing,
Turn smoke-box, fluid inlet and outlet, dividing plate, bobbin carriage, bifilar stream around heat exchange of heat pipe, stove water inlet pipe, air bleeding valve, Pressure gauge, core cylinder, stove
Gallbladder stay bolt, corrugated flue, smoke exhaust pipe, condensate outlet, blowoff valve and box-type heat exchanger.It is characterized in that: bifilar stream changes around pipe
Hot device is positioned at housing upper, by dividing plate, the fluid in bobbin carriage is divided into two parts；Flue and box-type heat exchanger are positioned under housing
Portion；Flue is waveform, and its front end is welded in and turns smoke-box, rear end welding ellipsoidal head, strile-back type centered by combustion system；Box
In heat exchanger, heat exchanger tube is arranged according to equilateral triangle, and its import welding turns smoke-box, exports the smoke pipe that runs in.Corrugated flue and box change
Hot device is by stove water soaking.
Described bifilar stream is wrapped on core cylinder according to certain angle around the heat exchanger tube of heat exchange of heat pipe, the winding side of adjacent two layers
To on the contrary.
Separating with dividing plate in the middle of described bobbin carriage, heated fluid A, B walk bobbin carriage dividing plate both sides respectively.
Described box-type heat exchanger is positioned at below flue, plate welding form, and two-port is that boiler smoke is imported and exported；On it
Lower flat board is the tube sheet of box-type heat exchanger heat exchanger tube, and the heat exchanger tube of box-type heat exchanger is pressed equilateral triangle and arranged.
Described flue is middle position major diameter flue, and strile-back type centered by its internal-combustion mode, flue and combustor are common
Composition combustion of natural gas region.
It is provided with blow-off pipe bottom described boiler shell, at smoke exhaust pipe, is provided with condensate discharge pipe.
Compared with prior art, the invention has the beneficial effects as follows: the most bifilar stream tilts to twine around the heat exchanger tube of heat exchange of heat pipe
It is wound on core cylinder, is beneficially back to lower portion thereof along tube wall after steam condensation, the winding direction phase of adjacent two layers heat exchanger tube
During rising and heat exchanger tube fully carries out heat exchange to anti-beneficially steam, there is not flow dead；2. in bobbin carriage every
Plate can allow two kinds of fluids pass in and out bifilar stream around heat exchange of heat pipe from different import and export respectively, and this structure can realize simultaneously to two
Plant fluid to heat, save time conveniently；3. the heat exchanger tube of box-type heat exchanger is arranged according to equilateral triangle, and high-temperature flue gas laterally rushes
Brush heat exchanger tube, convection transfer rate substantially increases, and improves boiler efficiency；The water of the bottom heat exchange by box-type heat exchanger in stove
Heating surface of tubes rises near corrugated flue after tentatively heating, and comes to life after continuing to be heated；The heat exchanger tube of box-type heat exchanger,
Tube sheet and weld seam are all by stove water soaking, and thermal-flame does not directly contact with weld seam, can be with the generation of Crack prevention；4. center is returned
The combustion system of combustion adds combustion flame residence time in flue, and Radiant exothermicity is increased, and so can reduce
The area of the convection heating surface of back-end ductwork, makes boiler structure be simplified, thus reduces boiler floor space, and reduction is fabricated to
This；5. furnace pressure subatmospheric, the boiling point of stove water is less than 100 DEG C, so energy consumption is relatively low；Boiler internal is negative pressure, will not
Blast, so the safety coefficient of boiler is high；6. ellipsoidal head ensure that combustion flame when a backhaul turns to two return without
Dead angle, Minimal energy loss.

Detailed description of the invention
Further illustrate the detailed description of the invention of novel bifilar stream central flame flame vacuum boiler below in conjunction with the accompanying drawings.
The processing technology of novel bifilar stream central flame flame vacuum boiler: corrugated flue one end ellipsoidal head is sealed,
Then by it with turn smoke-box and be welded as a whole.Box-type heat exchanger is that four pieces of plate weldings form, and one end connection turns smoke-box, the other end
Connecting smoke exhaust pipe, some heat exchanger tubes are welded on panel according to equilateral triangle arrangement；At bifilar stream around heat exchange of heat pipe
Successively it is wound around heat exchanger tube on core cylinder, then heat exchanger tube correspondence respectively is assigned to bobbin carriage median septum both sides, it is ensured that fluid the most of the same race is not
Can join mixed, the most bifilar stream is fixed on boiler shell top around heat exchange of heat pipe；Finally miscellaneous part is arranged on housing corresponding
Position.
Further illustrate the work process of novel bifilar stream central flame flame vacuum boiler below in conjunction with the accompanying drawings.
Preparatory stage: carry out stove water softening, deoxygenation processes, and adds a certain amount of by stove water inlet pipe to enclosure interior
Soften water.
Combustion process: from the flame that burner nozzle is spouting, arrive ellipsoidal head by corrugated flue, through ellipse
Return to turn smoke-box after shape end socket, then the heat exchanger tube of transversal flow box-type heat exchanger, finally discharge from smoke exhaust pipe.
Heating process: boiler internal was pumped into before normal combustion the state with certain vacuum degree, then allows burning
Device normal combustion.Stove water is heated boiling under the heat exchanger tube of box-type heat exchanger and the heating of corrugated flue, owing to being negative pressure in stove,
So stove water seethes with excitement when less than 100 DEG C, steam condenses around the heat exchanger tube surface of heat exchange of heat pipe at bifilar stream after rising, and puts
Going out vaporization latent heat tube fluid, the condensed fluid after steam condensation continues heated in falling back to stove.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
