Description
Technical field the present invention relates to a kind of flue gas waste heat recovery aciculiform pipe waste heat boiler, can be widely used in the industrial silicon furnace flue gas waste heat recovery.
The background technology industrial silicon furnace is used to smelt manufacture silicon, mostly adopts the sack cleaner purifying and dedusting abroad, and the boiler recovery waste heat is set before the deduster.At present, the UTILIZATION OF VESIDUAL HEAT IN technical applications of China constantly enlarges, but in industrial silicon, silicomangan manufacturing field, the comprehensive recovery technology of fume afterheat still relatively is short of, the easy dust stratification of existence, the problem that flue gas resistance is big.
Summary of the invention the object of the present invention is to provide that a kind of compact conformation, cost are low, flue gas cooling, fume afterheat utilization, energy-saving and emission-reduction, environmental protection, raising generating efficiency, reduce that cigarette ash gathers, flue gas resistance is little, heating surface is big, heat exchange area is big, heat transfer efficiency is high, realize the flue gas waste heat recovery aciculiform pipe waste heat boiler of fume afterheat cascade utilization, shatter-proof noise reduction.
In order to achieve the above object, flue gas waste heat recovery aciculiform pipe waste heat boiler of the present invention comprises support; Be installed in the outlet smoke box in the support; Rack-mount side's economizer is installed in the low pressure evaporator of economizer top, is installed in the high pressure evaporator of low pressure evaporator top; Be installed in the superheater of high pressure evaporator top, be installed in the import smoke box of superheater top.
Flue gas waste heat recovery aciculiform pipe waste heat boiler of the present invention, said economizer is aciculiform pipe economizer.
Flue gas waste heat recovery aciculiform pipe waste heat boiler of the present invention; Its operation principle is: from the flue gas of industrial silicon furnace outlet, to exhaust-heat boiler inlet, flue gas flows from top to bottom through flue; Flow through superheater, high pressure evaporator, low pressure evaporator and economizer; Discharge chimney at last, flue-gas temperature drops to 180 ℃ from 450 ℃, and the heat that is discharged is used for making water to become 0.6MPa low-pressure saturated steam and 1.6MPa superheated steam.The superheated steam that produces is supplied with the steam turbine generating, and the low-pressure saturated steam of generation then gets into the female pipe of low-pressure steam, supplies the oxygen-eliminating device deoxygenation to use.
Flue gas waste heat recovery aciculiform pipe waste heat boiler of the present invention, economizer mainly is used for reclaiming discarded low level energy, improves feed temperature.In order to prevent that economizer surface receives cold end corrosion, the feedwater that requires to get into economizer reaches uniform temperature.
Flue gas waste heat recovery aciculiform pipe waste heat boiler of the present invention, in order to improve the heat transfer temperature and pressure of superheater, economizer, it is that working medium and flow of flue gas are in the opposite direction that superheater section, economizer section adopt counter-flow arrangement, the evaporimeter section still adopts following current to arrange.
Flue gas waste heat recovery aciculiform pipe waste heat boiler of the present invention, waste heat boiler heating surface is made up of economizer section, low pressure evaporator section, high pressure evaporator section and superheater section four parts.According to the waste heat boiler heat Balance Calculation, waste heat boiler will meet the requirements of superheated steam output, and delivery temperature is reduced as far as possible, and waste heat boiler must be provided with economizer, comes further to absorb low level energy in the exhaust with feedwater.Like this, the steam production of feed temperature, increase waste heat boiler can be improved on the one hand, on the other hand, the effective rate of utilization of evaporimeter section heating surface can be improved.
Flue gas waste heat recovery aciculiform pipe waste heat boiler of the present invention adopts forced circulation, and promptly vapour, water conservancy project matter are to drive according to external force feed pump, hot water circulating pump in pipe, like this, heating surface is arranged do not received any restriction, and it is compact that heating surface is arranged.Thereby, compact overall structure, unit heat metal consumption is low, and cost is low.
Flue gas waste heat recovery aciculiform pipe waste heat boiler of the present invention; Heating surface area on the unit length is big, is 1.3 times of spiral fin coil, and the argon arc welding welding is all adopted in butt weld; Its welding quality improves than manual welding quality greatly, and volume, the weight of equipment reduce significantly.Thereby under identical heat exchange area, equipment investment reduces greatly, aspect the apparatus arrangement installation, for the user provides than large space.Compact conformation, heat transfer efficiency is high.
Flue gas waste heat recovery aciculiform pipe waste heat boiler of the present invention with the cooling of the flue-gas temperature degree of depth in the industrial silicon furnace, reclaims the generating of flue gas heat driving steam turbine, reaches energy savings, environmental protection, the purpose of raising generating efficiency.
Flue gas waste heat recovery aciculiform pipe waste heat boiler of the present invention; When industrial silicon furnace moves, through absorbing exhaust waste heat, required superheated steam and the required saturated vapor of heating oxygen-eliminating device water but generation steam supply turbine generates electricity; Thereby fuel savings; Improve the utilization rate of fuel energy, satisfy industrial silicon technology simultaneously and make requirement, reach the purpose of not only economy but also energy-saving and emission-reduction.
Flue gas waste heat recovery aciculiform pipe waste heat boiler of the present invention is because aciculiform bobbin rib is a kind of cantilever design, under the percussion of air-flow; The pin rib produces vibration; Make cigarette ash be difficult to long-pending knot, add that the strong turbulent flow of flue gas washes away, it is stronger from the deashing ability that aciculiform pipe heat exchange element is had.
Flue gas waste heat recovery aciculiform pipe waste heat boiler of the present invention adopts cantilevered aciculiform pipe enhanced heat transfer component, has expanded heating surface.Compare with conventional heat transfer element; The heating surface of water pipe cigarette side can increase greatly, forms strong turbulent flow when flue gas is flowed through the aciculiform tube-surface simultaneously, self-vibration under strong action of turbulent flow; Play and improve heat transfer efficiency and reduce the effect that cigarette ash gathers; Effectively solve traditional waste heat boiler and be prone to dust stratification, the difficult problem that flue gas resistance is big, and effectively increase heat exchange area.Simple in structure, the thermal efficiency is high, and service life is long, and is safe and reliable, easy to maintenance.
Flue gas waste heat recovery aciculiform pipe waste heat boiler of the present invention, said economizer adopts cantilevered aciculiform pipe enhanced heat transfer component, and extended surface improves heat transfer efficiency.
Flue gas waste heat recovery aciculiform pipe waste heat boiler of the present invention adopts two technology of pressing, design high pressure and low pressure evaporator.Produce low-pressure saturated steam, be used for deoxygenation; Produce high pressure, superheated steam, be used for generating, realize the cascade utilization of fume afterheat.
Flue gas waste heat recovery aciculiform pipe waste heat boiler of the present invention, because the self structure characteristics of device structure design and aciculiform pipe make its characteristics with noise elimination, therefore, equipment can play the effect of noise elimination, shatter-proof noise reduction.
In sum, flue gas waste heat recovery aciculiform pipe waste heat boiler of the present invention, compact conformation, cost is low; The flue gas cooling, fume afterheat utilization, energy-saving and emission-reduction, environmental protection; Improve generating efficiency, reduce cigarette ash and gather, flue gas resistance is little, and heating surface is big; Heat exchange area is big, and heat transfer efficiency is high, realizes the fume afterheat cascade utilization, shatter-proof noise reduction.
