Summary of the invention:
Purpose of the present invention is exactly the non-premixed inverted gas condensing hot water heating stove of provide for the deficiency that solves prior art a kind of simple in structure, low cost of manufacture, obvious energy conservation.
The deal with problems technical scheme that adopted of the present invention is achieved in that and the present invention includes housing, smoke pipe chamber, blower fan and heat exchanger; It is characterized in that: the heat exchanger of lower housing portion setting has petticoat pipe, and blower fan is placed in the petticoat pipe lower end, connects with the smoke pipe chamber by smoke-intake pipe; Be provided with a group or more in the smoke pipe chamber and be the heat exchanger tube of independent path, the rounded or ellipsoidal structure of heat exchanger tube is arranged with helical form or corrugated; Upper end, smoke pipe chamber is a smoke exhaust pipe, and the bottom is the condensation mouth of a river; The gas distributing rod of burner is provided with two groups of above burner and gas nozzles.
The present invention compared with the prior art, beneficial effect is embodied in:
1, the present invention is mounted with petticoat pipe in the heat exchanger bottom, blower fan is placed in the petticoat pipe lower end, connect with the smoke pipe chamber by smoke-intake pipe, form and be inverted burning structure, simultaneously the smoke pipe chamber is used as condenser, in the smoke pipe chamber, be provided with a group or more and be the heat exchanger tube of independent path, solved the difficult problem of condensed water corrosion and blocking heat-exchanger, improve combustion position, reduced manufacturing cost.
2, the rounded or ellipsoidal structure of heat exchanger tube that is provided with in the smoke pipe chamber of the present invention is arranged with helical form or corrugated, increases heat exchange area, forms simple compact water channel.
3, simple in structure, the energy savings of the present invention, installation, maintenance, use are all very convenient.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is another structural representation of the present invention;
By the following examples, in conjunction with the accompanying drawings the present invention is further described;
Description of reference numerals: the warm water of 1-housing, 2-gas distributing rod, 3-gas nozzle, 4-Gas Pipe, 5-burner, 6-combustion chamber, 7-heat exchanger, 8-petticoat pipe, 9-blower fan, 10-triple valve, 11-goes out pipe, 12-hot water out pipe, 13-plate parallel operation, 14-water inlet pipe, 15-return pipe, 16-water pump, the 17-condensation mouth of a river, 18-and warms up into connection pipe, 19-smoke-intake pipe, 20-smoke pipe chamber, 21-and warm up out connection pipe, 22-heat exchanger tube, 23-pipe, 24-water outlet connection and manage;
Embodiment:
Referring to accompanying drawing 1; The present invention includes housing (1), smoke pipe chamber (20), blower fan (9) and heat exchanger (7); Burner (5) is settled on top at housing (1), and petticoat pipe (8) is set on heat exchanger (7), and blower fan (9) is placed in petticoat pipe (8) lower end, connects with smoke pipe chamber (20) by smoke-intake pipe (19); Be provided with one group of spiral heat exchange tube (22) in the smoke pipe chamber (20), connection pipe (18) connects with water pump (16) by warming up in heat exchanger tube (22) inlet side, goes out end and communicates with heat exchanger (7) by warming up out connection pipe (21); Gas distributing rod (2) is provided with two groups of burners (5) and gas nozzle (3); Upper end, smoke pipe chamber (20) is pipe (23), and the bottom is the condensation mouth of a river (17), and two interfaces in plate parallel operation (13) upper end connect with triple valve (10) and return pipe (15) respectively, and two interfaces in lower end connect with hot water out pipe (12) and water inlet pipe (14) respectively;
When using hot water, open the water source, pump working, start-up control part (not drawing among the figure), triple valve (10) phase inversion, open heat exchanger (7) and plate parallel operation (13) passage, blower fan (9) work, combustion gas sprays from gas nozzle (3) through gas distributing rod (2) by Gas Pipe (4), be mixed into burner (5) with the air that enters (direction of arrow), burning in combustion chamber (6), the high-temperature flue gas that produces during burning is through petticoat pipe (8), blower fan (9), enter smoke pipe chamber (20) by smoke-intake pipe (19), discharge from pipe (23); Recirculated water enters heat exchanger tube (22) through water pump (16) and carries out heat exchange with high-temperature flue gas, heat in the flue gas is fully used, water after the preheating heats through warming up out connection pipe (21) inflow heat exchanger (7) again, the hot water that forms enters plate parallel operation (13) through triple valve (10), at this moment cold water also enters plate parallel operation (13) from water inlet pipe (14) and carries out heat exchange, and heated hot water flows out for people to use from hot water out pipe (12); When using heating, triple valve (10) phase inversion, open heat exchanger (7) and go out pipe (11) passage with warm water, water pump (16) work, recirculated water is through heat exchanger tube (22), heat exchanger (7) and triple valve (10), goes out pipe (11) from warm water and flows out and enter radiator (not drawing the figure) and heat for people; Recirculated water flows back to from radiator again, enters water pump (16) through return pipe (15), heating once more in heat exchanger (7), alternate cycles; Since smoke pipe chamber (20) are as condenser, simple in structure, in heat exchanger (7), can not produce condensed water, having solved corrosion and the obstruction of condensed water to heat exchanger (7), the condensed water that smoke pipe chamber (20) produces is discharged from bottom condensate water mouth (17).
Another embodiment: referring to accompanying drawing 2; In smoke pipe chamber (20), be provided with two groups of spiral heat exchange tubes (22), heat exchanger tube (22) inlet side, upper end is water inlet pipe (14), going out end connects with heat exchanger (7) by water outlet connection pipe (24), connection pipe (18) connects with water pump (16) lower end heat exchanger tube (22) by warming up into, goes out end and communicates with heat exchanger (7) by warming up out connection pipe (21); When using hot water, cold water enters from water inlet pipe (14), in heat exchanger (7) heating, provides hot water from hot water out pipe (12) outflow through heat exchanger tube (22); When using heating, water pump (16) work, recirculated water heat in heat exchanger (7) through heat exchanger tube (22), and going out pipe (11) outflow from warm water afterwards, to enter radiator (not drawing the figure) be that people heat; Recirculated water flows back to from radiator again, enters water pump (16) through return pipe (15), heating in heat exchanger (7) once more, alternate cycles.
