Abstract
The utility model discloses a chimney capable of using waste heat which is composed of an outer chimney (1), an inner chimney (2), a crack channel (3) between the outer chimney and the inner chimney, a blower (4) and a boiler (5). The high-temperature waste heat generated after the boiler (5) burns can be exhausted through the inner chimney (2) and can be passed to the crack channel (3) between the outer chimney and the inner chimney. The hot air can obtain 300-400 DEG C when the hot air passes through the blower, then the hot air recycled enters the boiler (4) serving as the energy resource of combustion air, and the purpose of using the waste heat can be obtained.
Description
Technical field:
The utility model relates to the chimney arrangement of saving the energy, especially a kind of chimney that can utilize waste heat.
Background technology:
Chimney be industrial commonly used also be in demand equipment, in the growing modern economy of industrial production, the requirement of chimney arrangement is also improved day by day.As everyone knows, the chimney role is to enter waste gas, in the environment of green industry, need reach the requirement of purification to toxic emission; On the other hand, when chimney advances also can take away a large amount of heat energy the same of discharging waste gas, these heat energy distribute the pollution that not only brings environment, main is the consumption that has increased fuel, influences the thermal efficiency of fuel.
Summary of the invention:
The utility model the technical problem that will solve be to overcome above-mentioned weak point, design a kind of chimney arrangement of saving the energy.
The utility model provides a kind of chimney that can utilize waste heat.Design principle of the present utility model is for the heat in the waste gas that utilizes smoke stack emission removes the required fresh air of heating boiler, enters in the burner hearth after making it reach tens thousand of degree again.Can improve the thermal efficiency greatly like this, save the energy.
The chimney of this device is provided with trunk of funnel and inner chimney, the height used heat that produces after boiler combustion can be discharged by inner chimney, and pass to air in the crack passage between trunk of funnel and the inner chimney, by air blast the time, can reach 300-400 ℃, and then the circulation enter boiler as the combustion air energy, thereby reach the purpose of utilizing waste heat.
In order to improve the thermal efficiency, inner chimney can be with there being tuberculated pipe to make, and trunk of funnel is built into insulating brick, and air blast will be used heat resistant type, in order to avoid burn.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Description of drawings:
Fig. 1 is the chimney that the utility model can utilize waste heat
Crack passage 4-air blast 5-boiler between 1-trunk of funnel 2-inner chimney 3-trunk of funnel and the inner chimney
The specific embodiment:
The chimney that can utilize waste heat shown in Figure 1 is made up of the crack passage 3 between trunk of funnel 1, inner chimney 2, trunk of funnel and the inner chimney, air blast 4 and boiler 5.Boiler 5 communicates with being connected with inner chimney, and the two ends of air blast connect the crack passage 3 between inner chimney 2 and trunk of funnel and the inner chimney respectively.
When boiler combustion, because crack passage 3 places that connect between trunk of funnel and the inner chimney that are rotated in of air blast produce a negative pressure, the outer fresh air of stove enters air blast by the crack passage between trunk of funnel and the inner chimney, enter again in the boiler G, the used heat that height is arranged that the burning back produces is logical discharges in inner chimney, as long as chimney is enough high, in trunk of funnel, its heat can be by the air of inner chimney biography in crack.Owing to be the convection type exchange process, can reach 300～400 degree in air arrival place.Therefore, just can utilize waste heat during boiler combustion, reach the effect of saving the energy.
Claims (4)
1, a kind of chimney that can utilize waste heat is characterized in that this chimney comprises crack passage (3), air blast (4) and boiler (5) composition between trunk of funnel (1), inner chimney (2), trunk of funnel and the inner chimney.
2, a kind of chimney that can utilize waste heat according to claim 1 is characterized in that wherein described boiler (5) is connected with inner chimney (2) to communicate.
3, a kind of chimney that can utilize waste heat according to claim 1, the two ends that it is characterized in that wherein said air blast connect the crack passage (3) between inner chimney (2) and trunk of funnel and the inner chimney respectively.
4, a kind of chimney that can utilize waste heat according to claim 1 is characterized in that wherein said inner chimney (2) should be higher than trunk of funnel (1).
