Description

A kind of flue gas processing equipment of boiler
Technical field
The present invention relates to a kind of flue gas processing equipment of boiler, flue gas harmful substance can be removed, belong to gaseous contamination improvement and heat recovery technology field.
Background technology
Boiler is a kind of energy conversion, and the energy to boiler input has the forms such as the heat energy of the chemical energy in fuel, electric energy, high-temperature flue gas, and changes through boiler, and outwards output has the steam of certain heat energy, high-temperature water or organic heat carrier.The hot water produced in boiler or steam directly can provide required heat energy for commercial production and people's lives, it is possible to be converted to mechanical energy by Steam Power Equipment, or convert mechanical energy into electric energy again through electromotor.
The smoke evacuation flue-gas temperature of boiler is generally 120～250 DEG C, smoke evacuation flue gas in heat and steam in substantial amounts of evaporative heat loss in the every heat-energy losses of boiler, account for very big proportion, have the sensible heat of 8%～15% and the steam latent heat of 11%；Common boiler does not make full use of this energy, causes the wasting of resources, and directly discharge can cause environmental pollution.Additionally, due to containing CO in the smoke evacuation flue gas of boiler2、NOx、SO2, the harmful substance such as flue dust solid content, be air-polluting major pollutants, cause the atmospheric pollution phenomenon that haze, acid rain etc. are important.
Summary of the invention
The technical problem to be solved is to provide a kind of flue gas processing equipment of boiler, the heat energy of the available boiler smoke of this device, moreover it is possible to simultaneously the harmful substance in flue gas is purged.
The mentality of designing of the present invention, is design one smoke processing system；The smoke evacuation flue gas and the domestic water that make boiler carry out heat exchange, it is to avoid the thermal waste of boiler smoke；Meanwhile, utilize heat exchange to make smoke evacuation flue-gas temperature be reduced to steam below dew point, make the water vapor condensation in flue gas, form moisture film；Utilize the coil pipe fin shape layout of Patent design, make flue gas contact with moisture film in motor process, the most of CO in flue gas2、NOXAnd solid content is retained by moisture film, it is collected the condensed water containing solid content in flue gas and harmful gas processing.
The technical scheme is that a kind of flue gas processing equipment of boiler, including boiler, boiler exhaust gas pipeline, smoke processing system；Described smoke processing system is made up of shell, coil pipe, coil pipe fin, smoke inlet and exhanst gas outlet；Coil pipe coils arrangement in the enclosure in the shape of a spiral, and coil pipe fin is fixed on coil pipe；The coil pipe mouth of pipe by smoke outlet is water inlet, and the coil pipe mouth of pipe by smoke inlet end is outlet；The space surrounded between inner surface and the coil pipe appearance of described shell is exhaust gases passes；Smoke inlet is in shell left, and exhanst gas outlet is in the right of shell；Having hot well in shell lower inner surface, the lowest order of hot well is equipped with sewage draining exit；Sewage draining exit connects condensate processor and eliminating solid content and harmful gas is processed.
Described coil pipe fin is foliaceous, multi-disc coil pipe fin is fixed on the helical buckling side of coil pipe equally spacedly, make the blade tip free end being distributed in all coil pipe fins in a circumference coil pipe point to hollow part, be distributed in the coil pipe fin between a pitch coil pipe and keep staggering；The blade tip free end of every coil pipe fin has the degree of depth to cut seam.
Operation principle: the flue gas of 120～250 DEG C given off in boiler enters smoke processing system through boiler exhaust gas pipeline, flue gas is advanced by the multi-disc fin circuitous on smoke processing system；Flue gas can be made to slow down rapidly, reach gravity and be detained flue dust effect.Meanwhile, smoke evacuation flue gas carries out contacting heat exchange with coil pipe fin, and the flowing water in coil pipe is heated, and flue gas is cooled cools to below dew point.Owing to containing substantial amounts of water vapour in smoke evacuation flue gas, producing substantial amounts of condensed water in heat exchange temperature-fall period, fin surface condensation forms moisture film；Condensed water moisture film absorbs the most of CO in smoke evacuation flue gas2And NOXStick on coil pipe fin etc. harmful gas, also the harmful components such as the sulfur being detained in flue dust, arsenic, hydrargyrum, flue dust are retained simultaneously, drain through the sewage draining exit of outer casing bottom；The discharge capacity making harmful gas significantly reduces.
Additionally, under the effect of air-introduced machine, the flue gas of flowing blows to the coil pipe fin in smoke processing system, owing to the blade tip free end of every coil pipe fin has the degree of depth to cut seam, air-flow is by cutting seam, and coil pipe fin produces dither, will accumulate in sewage membrane or mud shake on coil pipe fin de-, reach automatic pollution removing effect, make coil pipe fin keep high efficiency heat transfer effect.
Compared with prior art, the invention has the beneficial effects as follows:
After the high-temperature flue gas smoke processing system flue gas waste heat recovery apparatus of boiler combustion, its flue-gas temperature gradually reduces to 30-50 DEG C, substantial amounts of obvious heat of smoke and steam latent heat are recycled, moisture and harmful substance in flue gas are greatly lowered, boiler efficiency decreases the discharge of pollutant while improving.By the present invention in that by the coil pipe fin shape layout of Patent design, improve heat transfer effect, reduce exhaust gas temperature.Can Mist heat recovering in a large number, condensed water uses as boiler replenishing water and utilizes, and has saved the energy；Substantial amounts of harmful substance can be made to be dissolved in condensed water and together discharge therewith simultaneously, decreasing the pollutant discharge to air.
The present invention is widely used in the boiler that power is 0.7～70 megawatt.
