Abstract
The utility model relates to a modularized waste heat boiler which comprises the main parts of an inlet flue duct, overheaters, an evaporator, an economizer, an outlet flue duct, a steam drum, and a steel frame platform; the inlet flue duct, the overheaters, the evaporator, the economizer, the outlet flue duct, and the steam drum are all independently formed modules; and the connecting surfaces of the modules are in correspondence. Further, heating pipes are reasonably arranged and the structural parameters of heat exchange pipes are optimized, so as to achieve the purpose of self-ash removal, and the heating pipes adopt finned tubes; a water supply preheater is arranged on the economizer, thereby solving the problem of low-temperature dew point corrosion; and compared with the prior art, the utility model has the characteristics of light weight, high heat efficiency, compact structure, convenient field installation and maintenance, easy operation, and long service life. The modularized waste heat boiler is a product replacing the old-fashioned waste heat boiler in china.
Description
One, technical field
The utility model belongs to the waste heat boiler equipment technical field, is specifically related to a kind of modularization waste heat boiler.
Two, background technology
Mainly there is following several problem in existing waste heat boiler:
1) major part all is the loose mail delivery, the on-the-spot installation, and installing generally needs 6 months, long construction period.Because the restriction of field condition is easy to cause hidden danger of quality, the health problem that also is subject to season and weather condition effect, especially insulation material is difficult to ensure the quality of products.
2) dust stratification of waste heat boiler convection heating surface is the technical barrier that is perplexing China's waste heat boiler development always, though taked various measures, effect is not ideal, and this has had a strong impact on the raising of China's waste heat boiler thermal efficiency.
3) low-temperature dew point corrosion of economizer is the key issue of the restriction China's waste heat boiler service life and the cycle of operation, though tested various materials, effect is also not too obvious, does not tackle the problem at its root, but also cost has been improved greatly.
4) the heating surface design is most of adopts light pipe, thereby makes it bulky, and floor space is many, and the unit steel quantity consumption is also very big, and anufacturability is very poor, thereby is difficult to guarantee its workmanship.
Three, summary of the invention
The purpose of this utility model just provides a kind of convenience quick for installation, can improve the modularization waste heat boiler of the thermal efficiency.
The technical solution adopted in the utility model is: the modularization waste heat boiler comprises several major parts such as inlet flue duct, superheater, evaporimeter, economizer, exhaust pass, drum and steelframe platform, the independent composition module of each critical piece of inlet flue duct of the present utility model, superheater, evaporimeter, economizer, exhaust pass and drum, abutted surface is corresponding mutually between each module.
The heating surface tube of evaporimeter of the present utility model and economizer all adopts spiral fin coil, and the heating surface tube of superheater partly adopts spiral fin coil.
The utility model is provided with feed water preheater at the economizer place.
Adopt modular design, have on-the-spot easy for installationly, save manpower, can shorten field installation time greatly, reduce mounting cost.The waste heat boiler of modular construction is on-the-spot to be installed about 1 month the time that only needs, and boiler body several days just can be all in place.The waste heat boiler body is made (comprising refractory cement) quality and is controlled easily in factory building, structure also can design more rationally, thereby the workmanship of boiler obtained great assurance, and this just lays a good foundation for the boiler long-term safety turns round.Thereby prolonged the service life of boiler.Generally can continuous operation 3～4 years and do not need maintenance.
Because can reduce fouling of heating surface effectively and accumulate rich experience aspect the employing finned tube, so novel waste heat boiler whole finned tubes that adopt on economizer and evaporimeter, the wing rate reaches 100%; Also reach more than 50% in convection current superheat section wing rate.
Because heating surface adopts fusion rate that finned tube adds finned tube to bring up to more than 90% by domestic 80% in a large number, therefore the heat exchange area of Unit Weight greatly increases, the waste heat boiler of same model, just the weight that might design is lighter, and floor space also can be smaller.
Compare with traditional waste heat boiler, the utlity model has following advantage: in light weight, the thermal efficiency is high, compact conformation, on-the-spot easy for installation, easy to maintenance, easy operating, life-span are long, it is the regeneration product of the old-fashioned waste heat boiler of alternative China.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model.
Five, the specific embodiment
The modularization waste heat boiler comprises inlet flue duct 1,1 # superheater 2,2# superheater 3, evaporimeter 4, economizer 5, exhaust pass 6, drum 7, steelframe platform 8 and feed water preheater 9.Wherein, the all independent composition module of inlet flue duct 1,1 # superheater 2,2# superheater 3, evaporimeter 4, economizer 5, exhaust pass 6 and drum 7, each module adopts flange to connect, the flange that intermodule is made up of identical length and width angle steel or channel-section steel, channel-section steel carries out seal weld after connecting with bolt again between each module, then press between each module insulation material and fill out, prevent smoke spillage to reach with the aluminosilicate refractory fiber felt of thick 25mm.Each module reinforcement also makes whole boiler neat in appearance under the situation of proof strength then point-blank.
Waste heat boiler is shutdown maintenance or periodic cleaning if desired, and the maintainer can be by being located between tube panel and the superheater, and between superheater and the evaporator section, and the manhole between evaporator section and the economizer enters in the stove.Repairing the pipe that leaks if desired also is very easily.
Rationally arrange heat pipe, the appropriate design tube pitch, the structural parameters of optimization heat exchanger tube have purpose to strengthen flue gas flow rate, reach the purpose from deashing.Add the telescopic efficient soot blower of design, solved the dust stratification problem basically.Owing to can reduce fouling of heating surface effectively and accumulate rich experience aspect the employing finned tube, the novel waste heat boiler all adopts finned tube on economizer 5 and evaporimeter 4, the heat exchange area of Unit Weight is greatly increased, this unit's of greatly reducing steel quantity consumption also makes the whole volume of waste heat boiler greatly reduce.
Reduce dew point corrosion by control exhanst gas outlet temperature, exhaust gas temperature is controlled on the reasonable levels, avoid the dew point corrosion temperature.In addition, improve economizer cold side inlet water temperature, make economizer 5 cold junction tube wall temperatures be higher than dew-point temperature, thereby avoided dew point corrosion by adopting feedwater preheater 9.
