Abstract

A kind of gas heating stove chimney, this chimney emission pipe adopts one group of flat tube, there are the structure of similar plate type heat exchanger, the simple feature of tubular heat exchanger structure, plate type heat exchanger heat transfer effect, exchange media traveled straight, counterflow exchange, the medium temperature difference is larger, resistance is little, and heat transfer effect is outstanding, is applicable to very much the waste heat recovery of gas heating stove, it is identical that port flows back to wind and smoke chimney with tradition, and old and new users all can use.

Description

Gas heating stove chimney
Technical field the utility model relates to field of heat exchange, is a kind of device that the heat after gas furnace burning is recycled by the waste gas residual heat after the absorption of stove heat exchanger.
Background technology is current, and after the heat produced during gas heating stove burning is absorbed by traditional stove heat exchanger, what waste gas residual heat had be used for heat cycles water, the stove of most of producer is directly discharged by exhaust duct, and exhaust temperature is at about 120 degree.The stove of waste-heat recirculated water, device is complicated, requires high, also will carry out Layout changing again to stove interior.
The smoke evacuation of existing traditional gas heating stove, return air, complete by flowing back to airduct, an exhaust duct is in backwind tube, and waste heat can not better reclaim.
Existing traditional shell and tube and plate type heat exchanger, import and export and have 4, can not be used in flowing back on the pipeline of airduct of gas heating stove, and cold fluid and hot fluid all will be turned back through two 90 degree, passage resistance is large.
Summary of the invention the object of the invention is the Novel chimney in order to solve a kind of Mist heat recovering heating combustion air making the resistance of exchange media traveled straight less that above-mentioned deficiency is invented.Through chimney heating, combustion air temperature can improve 30 to 60 degree, and household small-size gas furnace burner hearth high-temperature region does not reach 1500 degree that Nox generates in a large number, after increasing described device, because waste heat is better recycled, decrease energy resource consumption, decrease pollutant emission, energy-conserving and environment-protective.
Corresponding device comprises shell 1, isocon 2, one group of smoke exhaust pipe 3, one group of fresh inlet 5 on the deflector 4 of plate face perforate and shell tail end shell wall, in the enclosure, deflector sealed attachment is in the outside of fresh inlet 5, heat exchange ante-chamber inside plate shell inner cavity being divided into isolation and the smoke evacuation back cavity outside plate, in ante-chamber, isocon, smoke exhaust pipe, deflector is sealed attachment UNICOM successively, flue gas enters smoke exhaust pipe from isocon head end gas approach 7, heating tube wall, release heat, reduce temperature and enter back cavity 11 by deflector, flow out from exhanst gas outlet 8, fresh air enters ante-chamber from fresh inlet 5, the flowing of inverse flow of flue gas direction, absorb smoke evacuation tube wall heat, flow out from new wind outlet 6, enter in stove combustion-supporting along gas furnace return air channel, it is identical that outer cover port and isocon head end and tradition flow back to wind and smoke chimney, effective docking can be realized, see Fig. 1.
Further, smoke exhaust pipe is one group of flat tube, and the height of flat tube is identical with the height of corresponding outer casing inner wall.
Further, smoke exhaust pipe is one group of flat tube, and the higher primary school of flat tube is in the height of the outer casing inner wall of correspondence.
Further, smoke exhaust pipe is one group of pipe.
Further, outer 2 to the 3 centimetres of mounting block aerofoils of shell tail end mouth, deep bead is fixed on shell by connecting plate, and flue gas is discharged from tail end mouth to deep bead gap.
Further, outside deflector, shell suitably adds and grows to 20 cm, and extension housing being opened one group of hole is exhanst gas outlet 8, and shell tail end mouth is closed by deep bead 10, Fig. 1
Further, changing tabular deflector is tubulose mozzle, and mozzle head end connects UNICOM with smoke exhaust pipe tail end sealing, and mozzle afterbody extends to outer 20 centimetres of shell tail end, and port closed, it is exhanst gas outlet that tube wall opens one group of hole, all the other space-closeds of outer cover port.
Further, deflector is identical with isocon shape and structure, in the enclosure respectively sealed attachment UNICOM smoke exhaust pipe head and the tail two ends, described device in the duct between position, realize the object of UNICOM and heat exchange.
Further, flue gas is through smoke exhaust pipe, and heating tube wall, temperature declines, and the steam generation condensation in flue gas, for preventing the unordered drippage of condensed water, installs condensate pipe in the bottom perforate of shell tail end, the relevant position perforate of shell Inner guide pipe.
Description of drawings 1 is chimney basic structure schematic diagram.Shell 1, isocon 2, smoke exhaust pipe 3, deflector 4, fresh inlet 5, new wind outlet 6, gas approach 7, exhanst gas outlet 8, back cavity 11.
Fig. 2 is the structural representation of deep bead sealed attachment when chimney tail end mouth.Shell 1, isocon 2, smoke exhaust pipe 3, deflector 4, fresh inlet 5, new wind outlet 6, gas approach 7, exhanst gas outlet 8, condensate pipe 9, deep bead 10, back cavity 11.
What device described in detailed description of the invention was arranged on gas heating stove flows back to wind pipeline tail end, shell and isocon head end and gas furnace flow back to airduct connection UNICOM, form closed air draft and return air path, condensate pipe connects water receptacle.After start, under the effect of stove inner blower, flue gas enters isocon through exhaust duct, smoke exhaust pipe, heating tube wall, and temperature declines, water vapor condensation, and release latent heat, heating chamber wall, exothermic flue gas, by deflector, shell back cavity, outside exhanst gas outlet discharge chamber.Outdoor fresh air, enters in shell through fresh inlet, and it is combustion-supporting that absorption smoke evacuation tube wall heat enters combustion chamber.
Through the flue gas of described equipment, temperature significantly declines, and reduces energy resource consumption, energy-conserving and environment-protective.Described in comprehensive, this chimney adopts similar board-like flat pipe type structure, there is the simple feature of tubular heat exchanger structure, plate type heat exchanger heat transfer effect, exchange media traveled straight, counterflow exchange, the medium temperature difference is comparatively large, and resistance is little, is applicable to very much the waste heat recovery of gas heating stove, heat transfer effect is obvious, obvious energy conservation.
