Description
Technical field
The utility model relates to the boiler plant application, particularly relates to waste heat recovery that the tail gas of boiler produces at use device.
Background technology
Boiler is a kind of energy conversion, the forms such as heat energy of chemical energy in the fuel, electric energy, high-temperature flue gas are arranged to the energy of boiler input, and through the boiler conversion, outwards output has steam, high-temperature water or the organic heat carrier of certain heat energy.The original meaning of pot refers to the water container that heats at fire, and stove refers to the place of combustion fuel, and boiler comprises pot and stove two large divisions.The hot water that produces in the boiler or steam can be directly for industrial production and people's lives provide required heat energy, also can be converted to mechanical energy by Steam Power Equipment, or by generator mechanical energy is converted to electric energy again.Provide the boiler of hot water to be called hot-water boiler, be mainly used in life, a small amount of application is also arranged in the industrial production.The boiler that produces steam is called steam boiler, and is often referred to as boiler, multiplex in thermal power station, boats and ships, locomotive and industrial and mining enterprises.Boiler carries out simultaneously at " pot " and " stove " two parts, and water enters after the boiler, and boiler heating surface makes water be heated into hot water or the generating steam of uniform temperature and pressure in the heat transferred water that absorbs in boiler circuit, is drawn application.In the combustion apparatus part, heat is constantly emitted in fuel combustion, and the high-temperature flue gas that burning produces is by the propagation of heat, and with the heat transferred boiler heating surface, and self-temperature reduces gradually, is discharged by chimney at last.
Yet, continuous development along with society, the energy also is more next more in short supply, so all trades and professions are advocating thriftiness very all, yet the waste heat that boiler exhaust gas produces, but must not use at present, large good resource has been slatterned greatly, the flue-gas temperature that the most of boiler tails that move in China discharge is up to 150 degree, can therefrom waste many coal, increase the cost of processing, simultaneously, also improved workman's labour intensity, and hot gas flows to the outside, will certainly cause the pollution of air, cause mass energy to run off, not meet the demand of presentization development.
In sum, for the defective of prior art, need especially a kind of residual heat reclaiming apparatus for boiler vent gas, to solve the deficiencies in the prior art.
The utility model content
Do a large amount of wastes of heat for boiler exhaust gas in the prior art, and flow to the pollution that can cause environment in the air, the utility model proposes a kind of residual heat reclaiming apparatus for boiler vent gas, simple in structure, can effectively the direct filtration of the waste heat of boiler be recovered to again body of heater the inside, and flow process is simple, it is convenient to filter, practical, the energy is re-used.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of residual heat reclaiming apparatus for boiler vent gas, comprise body of heater, Rose Box, the top of described body of heater is provided with exhaust opening, be connected with the flue gas transfer tube between described exhaust opening and the Rose Box, described Rose Box inside is hollow structure, and Rose Box inside is equipped with seperator, side at seperator is provided with the smoke absorption device, its opposite side is provided with the hot gas guiding piece, and described smoke absorption device one side is provided with exhaust opening, and described hot gas guiding piece connects the hot gas case.
Between body of heater described in the utility model and hot gas case, be connected with the hot gas ingress pipe.
In an embodiment of the present utility model, an end of described seperator is equipped with fan, and its other end is provided with supporting seat.
Further, the arranged outside of described seperator has guard box.
The beneficial effects of the utility model are: this product structure is simple, easy to use, can be effectively and boiler carry out combination, the tail gas that boiler produces can directly enter into filter, in filter, hot gas and flue gas are separated, heat can use inferior, tail gas then directly enters the external world and emits, and belongs to waste gas filtering utilizing, and has saved Gas Resource, alleviated production cost, simultaneously also reduced workman's labour intensity, the automaticity of device is high, satisfies the demand of modernization development, modern design is easy to promote and use.
