Abstract
A heat exchanger, comprises that heat exchange core, cold fluid discrepancy pipe, hot fluid are come in and gone out and managed, isocon.Wherein a kind of discrepancy pipe of fluid is come in and gone out and is managed inside at another fluid.One fluid is come in and gone out in inner tube, and another fluid is come in and gone out between inner and outer tubes, and inner fluid is come in and gone out and established isocon between pipe and heat exchange core.The applicable flow velocity of this heat exchanger is fast, flow is large, requires the heat-exchange system that the resistance of ducting is less, especially applicable Household gas-burning heating stove waste heat recovery.Use after described device, smog discharge temperature is decreased to 40 degree left and right by 120 degree, and energy-saving effect is fairly obvious.
Description
Technical field the utility model relates to heat exchange field, is a kind of device that the waste gas residual heat after heat after gas furnace burning is absorbed by stove heat exchanger is recycled.
Background technology is current, and after the heat that gas heating stove when burning produces is absorbed by traditional stove heat exchanger, waste gas residual heat has is used for heat cycles water, and the stove of most of producer is directly discharged by exhaust duct, and exhaust temperature is in 120 degree left and right.The stove of waste-heat recirculated water, device is complicated, requires highly, also will carry out Layout changing again to stove inside.
Smoke evacuation, the return air of existing traditional gas heating stove, complete by flowing back to airduct, and exhaust duct is in backwind tube.
Existing traditional shell and tube and plate type heat exchanger, imports and exports and has 4, can not be used on the pipeline that flows back to airduct of gas heating stove, and cold fluid and hot fluid all will turn back through two 90 degree, and current resistance is large.
Novel practical content the purpose of this utility model is that invent in order to solve above-mentioned deficiency a kind of allows the new type heat exchanger of the less waste gas residual heat heating combustion air of the resistance of exchange media traveled straight.
Corresponding device is arranged on gas heating stove and flows back on wind pipeline, heat exchange core, diameter-change flow diversion pipe, inside connecting tube (hot fluid pipe), external connection pipe (cold fluid pipe), shell, condenser pipe etc., consists of.Mounting casing outside plate core, forms external connection pipe 6,8, and the end face of core is established isocon, and isocon is divided into upper and lower two parts it, realizes the object (in Fig. 1 shown in 2 and 4) of the isolation of cold and hot chamber, cold-hot wind shunting.Isocon connects inside connecting tube, and wherein inside connecting tube is arranged in the inside (shown in Fig. 11 and 5) of external connection pipe, can and traditional gas heating stove flow back to the effective closed butt joint of wind pipeline, inside connecting tube connects exhaust duct, external connection pipe connection backwind tube.The waste gas that heating stove is discharged is introduced into heating stove and flows back to wind and smoke chimney, then through inside connecting tube, isocon, import heat exchange core hot-wind inlet 9 and enter hot chamber, heating chamber wall, reduces temperature and outside the exhaust duct discharge chamber of hot chamber outlet 9, isocon, inside connecting tube and UNICOM's inside connecting tube.There is condensation in waste gas, through 9 passages, converge to 7 outflows in heat exchanger.Fresh air enters the opposite side of isocon through flowing back to the passage of the return air channel of airduct and the external connection pipe of connection and inside connecting tube formation, from heat exchange core import 11, enter the cold chamber of heat exchange core, absorbing cavity wall heat, improve temperature, from 11 outflows, the space surrounding with external connection pipe outside isocon enters inside connecting tube, enters the return air channel of heating stove, along return air channel, enters in stove combustion-supporting.
Further, heat exchange core is comprised of plank frame, has ripple on plate, and stream socket is interlaced arrangement on the sidewall of plate, and the axis of gateway is parallel with plate face.
Further, heat exchange core can be tubular structure, changes the shape of diameter-change flow diversion pipe, can realize the object of shunting.
Further, described device can be arranged in the end that gas heating stove flows back to wind pipeline, the hot fluid outlet proper extension of described device one side some, port closed is offered some apertures through-flow on sidewall; Inlet ports sealing is offered some apertures through-flow on its sidewall.
Further, because flue gas contains steam, when by heat exchanger, temperature declines, and condensation can occur, and described device is installed condensate pipe in diameter-change flow diversion pipe bottom.

The specific embodiment
Described device is arranged on flowing back on wind pipeline of gas heating stove, as a part wherein, the airduct that flows back to of inside connecting tube 1 and external connection pipe 6 and gas furnace connects, interior junction pipe 5 and external connection pipe 8 and lead to the outdoor airduct that flows back to and connect, 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 inside connecting tube through exhaust duct, diameter-change flow diversion pipe, and the hot chamber of heat exchange core, heating chamber wall, temperature declines, and water vapor condensation, emits heat.The exothermic flue gas of heating chamber wall, through isocon 4, outside inside connecting tube 5 and chimney inner tube discharge chamber.Outdoor cold air, the space surrounding outside backwind tube enters heat exchanger external connection pipe 8 and inside connecting tube 5 flows into cold chamber, and it is combustion-supporting that absorbing cavity wall heat enters combustion chamber.
Through the flue gas of described equipment, temperature can be reduced to below 50 degree by 120 original degree left and right, and the steam generation condensation in flue gas, emits latent heat.Described in comprehensive, this heat exchanger adopts plank frame, traveled straight, and counterflow exchange, the medium temperature difference is larger, and resistance is little, is applicable to very much the waste heat recovery of gas heating stove, and heat transfer effect is obvious, obvious energy conservation.
This explanation is for gas heating stove waste heat recovery, but is not limited only to this structure of this function.
