Description

Super particulate fume purifier

Technical field

The utility model relates to a kind of super particulate fume purifier, belongs to the environmental protection cleaner.

Background technology

After national environmental protection pollutant emission new standard promulgation in 1996, past smoke and dust eliminating technology commonly used has a big chunk to prove definitely inferior.Because can only removing common particulate, they can not remove super particulate.Though in " old standard period " contribution was arranged, faced the destiny that is eliminated after the execution " new standard ".Though some technology can be up to standard, be difficult to adhere to long-term use because of running cost is expensive; Some technology is because of being subjected to some condition restriction can not extensive use.

Summary of the invention

For adapting to demands of social development, overcome the deficiency that prior art exists, a kind of super particulate fume purifier is provided, flue dust and gaseous contaminant there are significant regulation effect, have higher scientific and technological content.

Interrelated data calls " dirt " to the particle of 1～100 micron grain size in the waste gas, and the particle of 0.001～1 micron grain size is called " cigarette ", promptly we at ordinary times the common particulate of indication be " dirt ", super particulate is " cigarette ".Soot is a kind of like the non-gas of gas, and like solid non-solid material, handling with the method for dedusting can only be futile effort, should spend except that the method for gaseous state pollutant to administer.Packed bed is the better method that purifies gaseous contaminant in the past, and we are used for super particulate fume purifier with it, so obtained desirable effect.Super particulate fume purifier, comprise the air inlet pipe of fixedlying connected with clarifier body bottom, the escape pipe at clarifier body top, blower fan and chimney, link to each other between air inlet pipe and clarifier body bottom space and ponding, can be positioned at top between bottom space and ponding by the carriage of flue dust, fixedly connected with the clarifier body, carriage is formed packed bed with the packing layer that is placed on it, sparge pipe and water spray halter inject in the clarifier body, be positioned at packing layer top, dewatering plate is fixedly connected on clarifier body top cone place, the top of sparge pipe and water spray halter, blower fan is placed between escape pipe and the chimney.Be connected to sedimentation basin with pipeline between clarifier body bottom space and ponding, sedimentation basin communicates with clear water reserviors, is connected water pump between clear water reserviors and the sparge pipe.Blower fan also can adopt the air blast mode, also can adopt exhausting.Gaseous contaminant in all right smoke treatment of this device.The clarifier body can be made different shape as required, as circle, and square or rectangular or the like.It also can be made into civil engineering equipment, be built at the scene with brick, also can make iron and steel, directly installs and uses.This device is applicable to flue dust and the gaseous contaminant that various industries produce.Also can not establish dewatering plate.

Super particulate fume purifier is skillfully constructed, and modern design is cheap, widely applicable, and running cost reduces by 25% than other existing equipment, and the flue dust clearance reaches 98～99.5%, and gaseous contaminant (contains SO ₂), clearance reaches 85～95%, and the flue gas that is various look attitudes is become colourless cigarette, and non-secondary pollution.

The specific embodiment

Super particulate fume purifier, comprise the air inlet pipe 1 of fixedlying connected with clarifier body 13 bottoms, the escape pipe 7 at clarifier body 13 tops, blower fan 8 and chimney 9,2 link to each other between air inlet pipe 1 and clarifier body 13 bottom spaces and ponding, fire bars formula or net like carriage 3 are positioned at 2 tops between bottom space and ponding, fixedly connected with clarifier body 13, carriage 3 is formed packed bed with the packing layer 4 that is placed on it, sparge pipe and water spray halter 5 inject in the clarifier body 13, be positioned at packing layer 4 tops, dewatering plate 6 is fixedly connected on clarifier body 13 top cone places, the top of sparge pipe and water spray halter 5, blower fan 8 is placed between escape pipe 7 and the chimney 9.2 usefulness pipelines 14 are connected to sedimentation basin 12 between clarifier body 13 bottom spaces and ponding, and sedimentation basin 12 communicates with clear water reserviors 11, are connected water pump 10 between clear water reserviors 11 and the sparge pipe 5.Blower fan 8 also can adopt air blast, be placed on air inlet pipe 1 before.This device also can not established dewatering plate 6.

Flue gas enters between bottom space and ponding 2 from air inlet pipe 1, pass the fire bars formula or net like carriage 3 enters packing layer 4, flue gas is from tortuous rising the between the slit of packing layer 4, grit in the flue gas is under sparge pipe and water spray halter 5, bump with the water on the globule and packing layer 4 surfaces, caught by water, thereby enter the liquid phase main body by the gas phase main body.Also can be understood as toward dirty water and form a liquid film in the filler appearance, outside moisture film, form an air film toward the flue gas that rises, liquid film and air film frequently intersect at the volley and material Transfer take place, and particle in the flue gas and gaseous contaminant are delivered in the liquid film.Rise from the slit between itself and the clarifier body 13 through dewatering plate 6 then, carried out entering again after the dehydration escape pipe 7 during this, because the swabbing action of blower fan 8 enters chimney 9 backs and gets rid of.Water pump 10 is water suction sparge pipe and water spray halter 5, and water is sprayed on the packing layer 4.The surface of each piece filler all is soaked in water and water is arranged, at last water is concentrated between bottom space and ponding 2, flow into sedimentation basin 12 again, flow into clear water reserviors 11 after the clarification, enter new circulation then toward dirty.Water carries out closed circulation in the whole governance process, a certain amount of water of the every day of supply on demand, but do not allow to the external environment draining.If clarifier body 13 is than higher, flue gas arriving before the escape pipe 7 exclusion, also can not be provided with dewatering plate 6 in the process of handling.Before blower fan 8 also can be arranged on air inlet pipe 1, air blast in clarifier body 13, effect is the same.If not only remove flue dust, and to remove SO simultaneously ₂, at this moment can adopt lime masonry filler, the clear water and the lime stone of sparge pipe and 5 ejections of water spray halter all possess the flue dust of removal simultaneously and absorb SO ₂Effect.Also can take to spray milk of lime and use the filler of not participating in chemical reaction, can remove SO equally from sparge pipe and water spray halter 5 ₂This device is applicable to flue dust and the gaseous contaminant that various industries produce, and is widely applicable.The clarifier body can be made different shape as required, as circle, and square or rectangular or the like.It also can be made into civil engineering equipment, be built at the scene with brick, also can make iron and steel, directly installs and uses.
