The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing:
Housing 2 tops are fixedly connected with tangential admission pipe 17, are fixedly connected with speedup guide plate 15 in tangential admission pipe 17, the exit of speedup runner, and promptly speedup guide plate 15 is equipped with water atomizing nozzle 16 near a side of housing 2.Whirlwind in fixedly being equipped with one heart in the housing 2, the sub-bottom of interior whirlwind is the tangential admission section, the tangential admission section is that urceolus 12, inner core 13 and tangential admission mouth 18 are formed, and tangential admission mouth 18 connects firmly between urceolus 12 and inner core 13, makes urceolus 12 inner cores 13 tangential admission mouths 18 be unified into an integral body.Interior whirlwind middle part is a circular cone anemostat 10, and the bottom of circular cone anemostat 10, urceolus 12 upper edges are connecting firmly steam reflection cone 11.The sub-top of interior whirlwind is that the top of circular cone anemostat 10 is connecting firmly cylindrical straight tube 8, is installing annular shutter 5 at cylindrical straight tube 8 centers, has exhaust outlet 6 on the upper top cover plate of shutter 5, and shutter 5 bottoms are connecting firmly bipyramid reflector 3.The cylindrical straight tube 8 outer annular conduits 9 that are fixed with are that one group of tangential water spout 7 supplies water by annular conduit 9, and tangential water spout 7 is distributed on the top top board of circular cone anemostat 10, and water are sprayed on the inwall of circular cone anemostat 10 and form moisture film.The center of the sub-lower tangential air inlet of interior whirlwind section is fixed with opposing steam flow pipe 1, has tangential outlet 19 in the bottom of opposing steam flow pipe 1, more than is main frame of the present invention.
Main frame of the present invention is installed on the detritus tank 22, and 24 is water purifying tank, and detritus tank 22 offers slag trap 20 with water purifying tank 24 usefulness spilling water wall branches, and water pump 21 is housed on the water purifying tank 24.Water in the pond is to contain buck.
Exhaust outlet 6 links to each other with air-introduced machine.
During work, the flue gas that boiler is discharged flows into tangential admission smoke pipe 17, along with flow area dwindles progressively speedup, at tangential admission smoke pipe end, further speedup is to high flow rate under the effect of speedup guide plate 15 for inboard fraction flue gas, and most of flue gas tangentially enters housing 2 and the molecular annular dedusting area of interior whirlwind with low flow velocity.One group of atomizing spray mouth 16 is housed in the exit of speedup guide plate 15, and the water that water pump 21 is sent here is by water atomizing nozzle 16 ejections, and water atomizes under the effect of the high speed flue gas stream of water atomizing nozzle 16 and the outflow of speedup runner.Water smoke together tangentially enters annular dedusting area with high speed flue gas stream.In the process of screw, water smoke mixes with flue gas and cut the 2 inwall sedimentations of flue gas flow direction housing, forms moisture film and flows back to detritus tank 22 along barrel at housing 2 inwall coalescences.In centrifugation, discharge housing 2 with the most of grit capture in the flue gas and with moisture film under the acting in conjunction of water smoke droplet collision interception capture and film entrapment.
In the process that water smoke and high-temperature flue gas mix, SO in alkali in the water and the flue gas
2Carry out chemical reaction Deng oxious component, reach the purpose of desulfurization.There is the heat absorption of part water to flash to steam simultaneously.The severe of these water vapours is less than the severe of flue gas, under the effect of centrifugation, be enriched in the internal layer of cyclone, during tangential admission mouth 18 upper edges of the flue gas stream lower tangential air inlet of whirlwind section in housing 2 and the molecular annular dedusting of interior whirlwind space inside spin come downwards to, the flue gas stream that the air-flow internal layer is rich in water vapour cycle stream and participating in the fresh smoke on the sub-outside wall surface of whirlwind in the effect lower edge of the sub-steam reflection of the interior whirlwind conical surface 11, make the water vapour in the fresh smoke cross the degree of saturation raising, the enhancing water vapour is moistening to small dust, coalescence, the capture effect has also reduced the smoke moisture that enters interior whirlwind.
The inner core 13 of whirlwind and the annular space between the opposing steam flow pipe 1 and spiral were up to anemostat 10 in flue gas stream tangentially entered under the effect of sub-tangential admission mouth 18 deflectors of interior whirlwind.Along with flue gas flow rate descends, static pressure gos up, water vapour strengthens moistening, coalescence, the capture effect of micronic dust, when coalescence during to greater particle size, under centrifugation, from flue gas stream, separate, by the film entrapment on the sub-inwall of interior whirlwind, and descend with moisture film and between urceolus 12 and inner core 13, to flow back to detritus tank 22.
Because the severe of steam is less than the severe of flue gas, under centrifugation to cyclone center's enrichment, when being threaded to 3 times reflectings surface of bipyramid reflector on the air-flow center enrichment air-flow reflexed backspin under the effect of reflector 3 of steam, and inflow opposing steam flow pipe 1, tangential outlet 19 outflows by opposing steam flow pipe 1 bottom participate in the flue gas stream that newly enters interior whirlwind, improve the degree of supersaturation of steam in the flue gas, strengthen moistening, coalescence, the trapping ability of steam, also reduce exhanst gas outlet humidity particulate.Be threaded to the cylindrical straight tube 8 on top on the flue gas of outer relatively drying.The annular shutter 5 of cylindrical straight tube 8 centres dress is according to the design of inertial dust collection principle, and the small dust-laden water droplet in the flue gas is removed, and flue gas is being turned back on the conical surface on the bipyramid reflector 3 by behind the annular shutter 5, flows to exhaust outlet 6.
Detritus tank 22 is basic components of the present invention, main frame of the present invention just is installed on the detritus tank 22, the water level of detritus tank 22 floods certain depth with the bottom of main frame of the present invention, form water seal, guarantee the air-tightness requirement of main frame of the present invention, make the lime-ash sedimentation in the backwater simultaneously, the lime-ash that has been deposited to detritus tank 22 bottoms transfers out detritus tank 22 by slag tapping equipment 23, when detritus tank 22 water levels were higher than spilling water wall end face, water purifying tank 24 was gone in the water overflow in the detritus tank 22.Slag trap 20 is used to prevent that detritus tank 22 water surface scum silica frost from entering water purifying tank 24, the water pump 21 of dress recycles the gas cleaning water for water atomizing nozzle 16 and tangential water spout 7 water purification pumping endlessly on the water purifying tank 24, reduce water consumption, prevent the secondary pollution that a large amount of drainings cause.
