Abstract
The invention relates to a double-layer hot blast stove with a reverse burning heating pipe. A burning system is formed by a coal storage reverse burning grate, a burning chamber, a hearth, a second time burning grate, a flame channel, a flue, an exhaust pipe and an induced draft fan under a pipe board. Air enters into a return air inlet and then into a lower wind channel from a lower part with the gravitation of the induced draft fan to scrub the hearth, the flame channel, the outer wall of the flue and strip fins on the flue and absorb high temperature radiation convective heat, and then enters into a hot air generating room at the upper part of the pipe board of the heating pipe heat exchanger to scrub a heat release segment of heating pipe fins and release the heat that is absorbed by a heat absorption segment of the heating pipe from the flue and transferred to the heat release segment of the heating pipe arranged in a heating pipe generating room, thereby, the air is heated up quickly and sent to occasions which need hot air by the induced draft fan. Burning conditions can be adjusted by regulating the wind amount with the induced draft fan that has a speed-changing motor under the instruction of a temperature transducer arranged at a hot wind outlet and a temperature controller in an automatic controlling box, thereby realizing automatic operation.

Background technology:
The low profile thermal wind furnace of existing coal-fired preparation hot-air, adopt burner hearth and tubulation structure, rely on the gas-gas heat exchange of metallic plate, pipe to add hot-air, because the coefficient of heat transfer of gas-gas heat exchange is low, hearth wall surface temperature height influences safe in utilization and life-span of hot-blast stove, in service simultaneously because the thermal (temperature difference) stress difference of tube sheet, easily cause tube sheet cracking, the flue gas string mixes, and is accidents caused.
Summary of the invention:
The objective of the invention is to design that a kind of employing double-layer grate naked light is counter burns solution smoke abatement and dust control, adopt hearth outer wall and strip fin in the air channel behind the convection current radiation heat transfer again through utilize heat-tube vacuum phase transformation superconduction heat exchange prepare clean hot air the efficient fuel coal heat pipe hot-blast stove.
Technical solution of the present invention:
Technical scheme of the present invention: the present invention burns flue (1) anti-burn grate (5) and the same flue of combustion chamber (9) burner hearth (2) (16) places lower air duct by the coal storage in the burner hearth is counter, and burner hearth is by the coal-fired heat pipe hot-blast stove of quirk (13) with the novelty of the anterior integrally welded employing heat-tube vacuum phase-change heat-exchange of the flue under the heat exchange of heat pipe tube sheet.
Double-layer inverse burning hot pipe hot-air stove of the present invention is arised from the front panel (4) together by the anti-same burner hearth of flue (1) (2) flue (1) top board (3) that burns of fire coal, its internal upper part is the storage coal chamber (6) that anti-burn grate (5) is arranged down, the cinder chamber of interior bottom (7), second-time burning fire grate (8) is arranged above the cinder chamber (7), in the middle of the two-layer fire grate is combustion chamber (9, firing door (10) (air intake) is arranged respectively on the plate in front, door (11) pokes fire, cleanout door (12) (little air intake) is regulated combustion conditions, combustion chamber (9) rear portion quirk (13), burner hearth (2) is by the same heat exchange of heat pipe of quirk (13) (14) tube sheet (15) underflue (16) plate sealing assembly welding, afterbody is that smoke exhaust pipe (17) and air-introduced machine (25) are formed the double-layer inverse burning system, and the bottom is air entering and returning mouth (26).
Heat exchange of heat pipe of the present invention (14) is divided into top for arranging the hot-air generation chamber (19) of ratio-frequency welding fin heat pipe (18) heat release section by tube sheet (15), the bottom is the flue (16) that heat pipe (18) endotherm section stretches into, the anterior same quirk of flue (16) (13) plate assembly welding, be welded with strip fin (20) at burner hearth (2) flue (16) outer wall, with placing the following lower air duct (21) of tube sheet (15), the air that enters from air entering and returning mouth (26) is entered after hot-air generation chamber (19) absorbs heat that heat pipe (18) heat release section discharges and heat by flue (16) burner hearth (2) and strip fin (20) convection current radiation heating again, deliver to the occasion of using hot blast by blower fan (22), have air-introduced machine (25) the interlocking levelling combustion conditions on same temperature controller of temperature sensor (23) (24) and the smoke exhaust pipe (17) to realize operation automatically at hot-blast outlet.
The present invention compared with prior art has following technique effect:
1, in anti-outer wall welding rod shape radiating fin (20) road all at a disadvantage that burns flue (1) and burner hearth (2) and quirk (13) of coal storage of the present invention.Discharge high temperature convection current radiant heat under airflow scouring, atmosphere temperature rising is fast, and thermal efficiency height, and guarantee that burner hearth (2) plate is not burnt out prolongs hot-blast stove service life.
2, the present invention adopts the heat exchange of heat pipe (14) of different working medium heat pipes (18) combination in middle low-temperature flue gas heat exchange, heat pipe (18) phase transition of vacuum superconduction heat exchange, exhaust gas temperature is low to be changed, thermal efficiency height, safe and reliable, simultaneously at burner hearth (2) flue (16) outer wall assembly welding strip fin (20), with placing lower air duct (21), utilization rate of waste heat height.
3, at the blower fan (25) of smoke exhaust pipe (17) back dress stepless speed-regulating motor, hot-blast outlet has temperature sensor (23) simultaneously, realizes that counter-burning coal-fired hot-blast stove moves automatically under temperature controller (24) instruction.
Description of drawings:
Fig. 1 looks cutaway view for master of the invention process.
Fig. 2 looks cutaway view for a left side of the present invention.
Referring to Fig. 1, Fig. 2 the invention process anti-burning flue (1) is arranged, burner hearth (2), top board (3), front panel (4), anti-burn grate (5), coal storeroom (6), cinder chamber (7), fire grate (8), combustion chamber (9), firing door (10), the door (11) that pokes fire, cleanout door (12), quirk (13), heat exchange of heat pipe (14), tube sheet (15), flue (16), smoke exhaust pipe (17), heat pipe (18), hot-air generation chamber (19), strip fin (20), lower air duct (21), blower fan (22), temperature sensor (23), temperature controller (24), air-introduced machine (25), air entering and returning mouth (26).
