Description

A kind of power economized boiler

Technical field

The utility model relates to a kind of energy conversion, and more particularly, it relates to a kind of boiler.

Background technology

Boiler is a kind of energy conversion, and the energy to boiler input has chemical energy, electric energy in fuel, and boiler exports steam, high-temperature water or the organic heat carrier with certain heat energy.The original meaning of pot refers to the water container heated on fire, and stove refers to the place of combustion fuel, and boiler comprises pot and stove two large divisions.The hot water produced in boiler or steam 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 are converted to electric energy again.There is provided the boiler of hot water to be called hot-water boiler, be mainly used in life, in industrial production, also have a small amount of application.

At present, the boiler on market, fuel, after stove combustion, produces and has the steam of a large amount of heat energy, these steam by Cemented filling to subsequent work link.And steam is carried in the duct, be certain to the energy that outwards waste is certain, and these energy are dissipated, and cannot be effectively utilized, waste very.And need combustion fuel just must pass into air in boiler, and generally air enter the temperature that can reduce in stove, so just make the efficiency of fuel combustion decline, be unfavorable for the burning of fuel.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of more energy-conservation and boiler that fuel economy is higher.

For achieving the above object, the utility model provides following technical scheme: a kind of power economized boiler, comprise boiler body, blast pipe and escape pipe, described escape pipe comprises transportation section and parcel section, described blast pipe comprises bringing-up section, bringing-up section is wrapped in the inside of escape pipe by described parcel section completely, the surface of described bringing-up section is provided with some fins in order to enlarge active surface, the outer surface of described transportation section and parcel section is provided with heat-insulation layer, described heat-insulation layer comprises ceramic fiber cotton layer, cement foamed flaggy, mineral wool layer, rock wool heat-preservation carpet veneer and glue powder polyphenyl particle layer.

The utility model is set to further: described fin is uniformly distributed in the surface of bringing-up section.

The utility model is set to further: described glue powder polyphenyl particle layer is arranged at the innermost layer of heat-insulation layer, and described ceramic fiber cotton layer is arranged at the outermost layer of heat-insulation layer.

By adopting technique scheme, the vapours that the fuel burnt down in boiler produces, the work of next stage is entered by escape pipe, and this escape pipe is provided with parcel section, and this parcel section is wrapped in the outside of blast pipe bringing-up section, so just makes vapours directly contact with blast pipe, air in blast pipe is heated, thus the air themperature entered in stove is raised relatively, make the burning in stove more rapid, better effects if.Compare other heat across pipe, the effect that obvious this direct mode of heating plays is more outstanding.And the fin of bringing-up section surface setting here, the contact area between vapours and blast pipe can be made to increase, better can play the effect of heating.And the heat-insulation layer of the outer setting at escape pipe, can be good at the loss that energy outwardly occurs preventing vapours too much in the process of conveying, reaches energy-conservation effect.Ceramic fiber cotton is by raw material high-temperature fusion in industrial furnace such as highly purified chamotte, alumina powder, Cab-O-sil, chromium sands, forms fluid.Then adopt compressed air spraying or get rid of silk with tumbling machine and become threadiness, cotton through condensers collection, a kind of heat preserving and insulating material of formation.Have lightweight, intensity is high, anti-oxidant, thermal conductivity is low, flexibility is good, corrosion-resistant, thermal capacitance is little and the feature such as sound insulation.Be arranged on outermost layer, make use of high, the soft model of its intensity, corrosion resistant feature, make its weatherability more outstanding, service life is more permanent.The main material of cement foam board is cement, adds hydrogen peroxide, hard calcium, flyash and cement blowing agent fusion foaming forms.Cement insulation board is the optimal insulation material of current wall thermal insulating and wall thermal insulating fire-blocking belt, and its advantage is: thermal conductivity factor is low, and high insulating effect is not burnt, waterproof, and strong with body of wall cohesive force, intensity is high, nonhazardous radiogen, environmental protection.Mineral wool belongs to a classification in glass fibre, is a kind of manmade inorganic fibre.Mineral wool is by melten glass fibrillatable, and form the material of cotton like, chemical composition belongs to category of glass, is a kind of inorganic fibre.Have that forming, bulk density are little, thermal conductivity Go-to-and-fro, insulation is adiabatic, sound absorption qualities is good, corrosion-resistant, stable chemical performance.Rock wool heat-preservation carpet veneer, is be primary raw material with natural basalt, after high-temperature fusion, makes artificial organic fiber by high speed centrifugation equipment, add special binding agent and dust laying oil simultaneously, then through heating cure, the rock wool heat-preservation goods be made into.Have fire prevention, pest control, corrosion-resistant, not containing asbestos, stable chemical performance, be Green Product, to human body and environmentally friendly, be easy to carrying and transport, the advantages such as maintenance cost is low.Glue powder polyphenyl particle is gently expected by rubber powder material, granular polystyrene and cement mixing forms, scene adds water and can use (i.e. adhesive polystyrene granule heat-insulating mortar), its heat-insulating property is better, construction is simple, the strong outside of cohesive force in addition finish coat mortar, fibre-reinforced anti-crack can solve the problems such as surface layer hollowing splits.Be set to the innermost layer of heat-insulation layer, the effect that its cementitiousness is strong can be utilized fully, make heat-insulation layer more firmly be fitted in pipe surface, play better heat insulation effect.
