Abstract
The utility model relates to a boiler, in particular to a multi-hole air preheater of a countercurrent single return type industrial boiler, which comprises smoke pipes and sleeves, wherein the concentric sleeves are arranged on the periphery of the smoke pipes in connection mode to form the air preheater. A plurality of holes are circumferentially arranged on the lateral side of the sleeve arranged at the low-temperature end of the air preheater, and holes are arranged on the lateral side of the sleeve arranged at the high-temperature end of the air preheater to be connected with an air blower or an air inlet of a boiler door. The multi-hole air preheater of the countercurrent single return type industrial boiler has the advantages of being simple in structure, small in investment, small in occupied space, convenient to construct and transform, flexible and various in arrangement modes and remarkable in energy-saving effect, and effectively improving heat efficiency of the boiler.
Description
Technical field
The utility model relates to boiler, relates in particular to the single return-stroke type Industrial Boiler of a kind of porous adverse current air preheater.
Background technology
At present, 90% above boiler only just is equipped with air preheater more than or equal to 20 tons/hour steam boiler or power more than or equal to the hot-water boiler of 14 megawatts at evaporation capacity, but the air preheater of brand involves great expense; That is to say; The air that boiler combustion consumed all is a room temperature, and not through heating or intensification, a large amount of heat energy is directly taken away (even through after economizer) by flue gas; Off-energy, the boiler inefficiency.
The utility model content
The utility model technical problem to be solved is: for fear of the deficiency of above-mentioned prior art, the single return-stroke type Industrial Boiler of a kind of porous adverse current air preheater is provided, has solved heat energy and taken away by flue gas and make the ineffective problem of boiler efficiency.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is:
The single return-stroke type Industrial Boiler of a kind of porous adverse current air preheater; Comprise chimney, sleeve; Be connected and installed concentric sleeve in the chimney periphery and form air preheater; Side at air preheater low-temperature end sleeve is arranged circumferentially a plurality of holes, in the side perforate of air preheater temperature end sleeve, connects air blast or fire door air inlet.
According to such scheme, described side at air preheater low-temperature end sleeve is arranged circumferentially 6-12 hole, and the diameter in hole is 5-10cm.
According to such scheme, described chimney is connected distance and is 15-30cm with the plane of sleeve, and the height of sleeve is at least 1m.
According to such scheme, described chimney is metal chimney or flue, and described sleeve is a metal sleeve.
Preferably, described chimney is the steel chimney, and preferred, described sleeve is the steel sleeve.
The operation principle of the utility model: the air through heating or intensification does not get in the concentric porous sleeve through a plurality of holes adverse current that the air preheater low-temperature end is arranged circumferentially; When boiler smoke process chimney; Because of boiler smoke has a large amount of heat energy; Can get into the air heat intensification formation hot blast of concentric porous sleeve to adverse current; Hot blast utilizes the heat energy of boiler smoke from perforate drainage to the boiler blower or the fire door air inlet of air preheater temperature end again, improves the operating efficiency of boiler.
The beneficial effect of the utility model is: simple in structure, and small investment, it is little to take up room, and construction is transformed convenient, and arrangement form is versatile and flexible, effectively improves boiler thermal output, and energy-saving effect is obvious.
Description of drawings
When Fig. 1 is the chimney setting, the structural representation of the utility model.
Fig. 2 be chimney tiltedly immediately, the structural representation of the utility model.
Wherein, 1-steel chimney, 2-steel sleeve, 3-air preheater low-temperature end, 4-air preheater temperature end.
The specific embodiment
Further specify the embodiment of the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1, the single return-stroke type Industrial Boiler of the described a kind of porous adverse current of this specific embodiment air preheater is when chimney is erect; Connecting apart from chimney at steel chimney 1 peripheral mounting plane is 20cm; Highly be the concentric porous steel sleeve 2 of 2m, hoop evenly is provided with 10 holes in the side of air preheater low-temperature end 3, and the diameter in hole is 7cm; In the perforate of the side of air preheater temperature end 4, connect air blast or fire door air inlet.
Referring to Fig. 2, the single return-stroke type Industrial Boiler of the described a kind of porous adverse current of this specific embodiment air preheater, chimney is tiltedly immediately; Connecting apart from chimney at steel chimney 1 peripheral mounting plane is 15cm; Highly be the concentric porous steel sleeve 2 of 1m, the hoop Lower Half evenly is provided with 6 holes in the side of air preheater low-temperature end 3, and the diameter in hole is 6cm; In the perforate of the side of air preheater temperature end 4, connect air blast or fire door air inlet.
The operation principle of this specific embodiment: through the air of heating or intensification, the hole adverse current that distributes through air preheater low-temperature end 3 side hoops does not get in the concentric porous steel sleeve 2; When boiler smoke shown in a among Fig. 1,2; During through steel chimney 1; Because of boiler smoke has a large amount of heat energy, can get into the air heat intensification formation hot blast of concentric porous steel sleeve 2 to adverse current, hot blast is from side perforate drainage to the boiler blower or the fire door air inlet of air preheater temperature end 4; The heat energy of boiler smoke is utilized again, improve the operating efficiency of boiler.
The beneficial effect of this specific embodiment is: simple in structure, and small investment, it is little to take up room, and construction is transformed convenient, and arrangement form is versatile and flexible, effectively improves the boiler operating efficiency, and energy-saving effect is obvious.
The specific embodiment of the utility model does not constitute the restriction to the utility model.
