Description
Technical field
The invention belongs to the heating energy equipment technical field, specifically a kind of can with boiler exhaust gas spring back over downwards below the burning zone and with heating pipe network in cold heat-conducting medium in the loop flow to and form the reverse split-type reverse heat exchanger that once heats back boiler of feeding post bake.
Background technology
As everyone knows, along with world population, economic increasing rapidly, energy resource consumption sharply increases.Adding today that sternness, living environment are endangered day by day environmental pollution day, the hope that people thirst for green, protection environment, energy savings is also strong day by day.Boiler is a heating equipment the most general in the city; Its main function is exactly the heating system heat supply for the user; Existing boiler leans in the combustion chamber thorax to accomplish the heat transfer process body of heater to need taller and biglyyer, also need higherly so not only waste the boiler room from the material to some extent by single, and the low temperature heat-conducting medium after the heat exchange is directly gone into heat cycles in the boiler through the heating pipe network loop; Supply with each user through pipe network again after reaching uniform temperature; And mostly existing boiler is coal-burning boiler, thus not only need consume a lot of coals by the direct-fired mode of low temperature heat-conducting medium, and can produce a large amount of boiler exhaust gas; These tail gas contain high concentration dust, temperature generally up to 250 ℃, directly are discharged into to cause serious environmental to pollute in the atmosphere; In addition, because the temperature difference between cold heat-conducting medium and the boiler can shorten the service life of boiler more greatly more.
Summary of the invention
The purpose of this invention is to provide a kind of can with boiler exhaust gas spring back over downwards below the burning zone and with heating pipe network in cold heat-conducting medium in the loop flow to and form the reverse split-type reverse heat exchanger that once heats back boiler of feeding post bake.
The objective of the invention is to realize like this: it includes the housing of gas approach and exhanst gas outlet; It is characterized in that: be provided with one by leading directly to the threeway exhaust gases passes that exhaust gases passes and retrograde exhaust gases passes are formed at the enclosure interior upside; Straight-through exhaust gases passes is communicated with gas approach and exhanst gas outlet, be provided with in the junction of straight-through exhaust gases passes and retrograde exhaust gases passes controlled tobacco curing air-flow to the upset baffle plate; Be provided with the heat-conducting medium inlet that is communicated with the cycle heat exchange chuck in the housing sidewall bottom, be provided with the heat-conducting medium outlet that is communicated with the cycle heat exchange chuck on housing sidewall top; In retrograde exhaust gases passes housing all around, be provided with that be communicated with heat-conducting medium outlet and heat-conducting medium inlet and cycle heat exchange chuck band flue gas rise mouth; The shell space on cycle heat exchange chuck top is that the shell space that flue gas rise chamber, bottom are communicated with retrograde exhaust gases passes is the Flue Gas Diffusion chamber, at the indoor backflow vent mouth that also is provided with of flue gas rise.
Bottom, said Flue Gas Diffusion chamber is arranged on pairing boiler coal seam downside.
The lower edge of said housing is provided with a shoot door.
Described heat-conducting medium is water or conduction oil or air.
The present invention possesses following advantage:
1, can burning be produced heat and cut apart the mode of heat exchange and downgrade body of heater, along with the dwarfing boiler room height of body of heater also can be downgraded relatively,
2, energy-efficient.After the present invention once heats, supply with boiler post bake quick heating, reduced the consumption of fuel, reduced boiler heat time heating time, reach energy-saving effect.
3, prolonged boiler service life.The heat-conducting medium after once heating and the temperature difference of boiler are dwindled, and have lowered owing to the infringement of the temperature difference to boiler.
4, the normal boiler exhaust temperature of discharging is discharged exhaust temperature and is significantly reduced up to more than 250 ℃ behind the present invention, and since can be an amount of remove the flue dust in the tail gas, thereby played the effect of protection environment.
5, safe and reliable, low cost of manufacture, easy to use.The present invention gets final product operate as normal under normal pressure, need not to increase power.
Description of drawings
Fig. 1 is a perspective view of the present invention.
To combine accompanying drawing below, to further explain of the present invention, but following instance only is the example among the present invention through instance, the rights protection scope of not representing the present invention and being limited, and rights protection scope of the present invention is as the criterion with claim.
The specific embodiment
As shown in Figure 1; Primary structure of the present invention includes the housing 1 of gas approach 6 and exhanst gas outlet 15; Be provided with one by leading directly to the threeway exhaust gases passes that exhaust gases passes 3 and retrograde exhaust gases passes 9 are formed in housing 1 inner upper side, straight-through exhaust gases passes is communicated with gas approach 6 and exhanst gas outlet 15, and retrograde exhaust gases passes 9 is arranged on below the burning zone; Be provided with in the junction of straight-through exhaust gases passes 3 and retrograde exhaust gases passes 9 controlled tobacco curing air-flow to upset baffle plate 5, upset baffle plate 5 connects joysticks 13; Be provided with water inlet 12 in the housing sidewall bottom, be provided with water out 7 in housing 1 side wall upper part; Be provided with the go up kitchen range formula cycle heat exchange chuck 10 of mouth 4 of and band flue gas that is communicated with in shell 1 body around the flue gas logical 9 that drives in the wrong direction with water out 7 and water inlet 12; Housing 1 space on cycle heat exchange chuck top is that housing 1 space that flue gas rise chamber 14, bottom are communicated with retrograde exhaust gases passes 9 is Flue Gas Diffusion chamber 11, in flue gas rise chamber 14, also is provided with backflow vent mouth 2.
For the holdup time of flue gas in diffuser casing prolonged, fully heat exchange, then 11 bottoms, Flue Gas Diffusion chamber are arranged on pairing boiler coal seam downside.
Be deposited in the flue dust in the housing 1 for the ease of cleaning, be provided with a shoot door 8 in the lower edge of housing 1.
During use, the present invention is connected on the water return pipeline of heating system, promptly water return pipeline connects water inlet 12, and water out 7 connects the boiler feed water mouth; Boiler flue gas outlet connects gas approach 6 of the present invention, and exhanst gas outlet 15 of the present invention connects chimney, when boiler is just lighted; Fired coal combustion is insufficient in the stove, and flue-gas temperature is not high, and density is bigger; Value is little, can make flue gas get into chimney from straight-through exhaust gases passes 3 and discharge through 5 upsets of joystick 13 control upset baffle plates; When the boiler fuel combustion was abundant, flue-gas temperature was high, and density reduces behind the expanded by heating; Through 5 upsets of joystick 13 control upset baffle plates; Make flue gas get into Flue Gas Diffusion chambers 11 from the flue gas logical 9 that drives in the wrong direction, Flue Gas Diffusion chamber 11 in the water heat exchange of cycle heat exchange chuck 10, and owing to the trend of flue gas and water is opposite; Not only heat exchange effect is fine; The flue gas temperature row also fully be reduced, and the flue gas after the heat exchange leads to chimney through backflow vent mouth 2 again and discharges through flue gas rise mouthful entering flue gas rise chambers 14 4.
In addition, outside the heat-conducting medium in the above-mentioned heating system dewaters, can also be conduction oil or air, its operation principle and water are in full accord, and the Therefore, omited is introduced.
In sum, realized the object of the invention.
