Description
Technical field
The invention belongs to a kind of dust collection method and device of dusty gas.
Background technology
Four classes are mainly contained at present for the equipment preventing and treating dust pollution, first electrostatic precipitator, electrostatic precipitation utilizes high-voltage dc that the gas molecule in air is ionized, produce a large amount of electronics and ion, move to the two poles of the earth under the effect of electric field force, dust granules in air-flow is encountered and bacterium makes it charged in moving process, electrically charged particle divides with air-flow under electric field force effect takes exercises to contrary pole plate, under electric field action, free ion in air will move to the two poles of the earth, voltage is higher, electric-field intensity is higher, and the movement velocity of ion is faster.Due to the motion of ion, interpolar defines electric current.During beginning, the free ion in air is few, and electric current is less.After voltage is elevated to certain numerical value, the ion near discharge electrode obtains higher energy and speed, and when they clash into the neutral atom in air, neutral atom can resolve into positive and negative ion, and this phenomenon is called air ionization.After air ionization, due to chain reaction, greatly increase at the number of ions of interpolar motion, the electric current (being referred to as corona current) showing as interpolar sharply increases, air has become conductor, high strong voltage catches subsidiary bacteria particles, and instant conductive punctures the cell membrane be made up of protein, reaches kill bacteria absorption dedusting.Such deduster is in running, cause dust removing effects to change owing to being subject to the height etc. of the dust stratification degree of dedusting cylindrical shell, cylindrical shell rapping deformation extent, the equidistant degrees of offset in negative and positive the two poles of the earth, discharge frequency thereupon, some fine particulates cannot be tackled, finally also can be in atmosphere floating.It two is water dust scrubbers, water dust scrubber be utilize dust in gas rotating centrifugal force and water to the suction-operated of dust to realize dedusting.Namely dusty gas tangentially enters deduster along deduster circular arc, form High Rotation Speed air-flow, dust is close to deduster inwall under the influence of centrifugal force, simultaneously, the water flow down from dust remover roof forms water membrane at deduster inwall, and dust dissolves in water, along with the flowing of water, outside discharge deduster, reach the object of purification dusty gas.The problem of this method mainly nozzle easily blocks, thus the inwall moisture film caused is uneven, cavity place easily knot dirt etc. affect the phenomenon that water system normally works.The method is owing to being subject to the impact of the uncertain factors such as coal dust burdening is how many, dust granules thing size, fireman's operant level simultaneously, directly affects the stable operation of dust removing effects and dust pelletizing system.It three is cyclone dust collectors.Cyclone dust removal is the centrifugal force utilizing the dust-contained airflow rotated to produce, the process separated from gas by particulate pollutant.When dust-contained airflow enters cyclone dust collectors by air inlet pipe, air-flow becomes circular motion from rectilinear motion.The overwhelming majority of swirling eddy becomes under screw along wall with cylinder, towards cone flowing, usually claims this to be contour stealth.Dusty gas produces centrifugal force in rotary course, and particle density being greater than gas gets rid of to wall, and particle, once contact with wall, just loses inertia force and leans on the momentum of entrance velocity and downward gravity to fall along wall, entering ash releasing tube.Rotate the outer rotational gas flow of decline when arriving centrum, draw close to deduster center because of conical contraction, its tangential velocity improves constantly.When air-flow arrives a certain position, centrum lower end, just with same direction of rotation in cyclone dust collectors by lower convolution on, continue motion of spinning.Finally, Purge gas, outside blast pipe ejector, claims this to be inward eddy usually.The particle of part collection at large is also discharged thereupon.Such cyclone dust collectors collect dust mainly through the mode of centrifugal force.Because the number of the size of its centrifugal force, particle quality, particle is variable, thus directly affect efficiency of dust collection.It four is sack cleaners, bag-type dust utilizes sack cleaner (a kind of dry dust removal apparatus), filter bag adopts the filter cloth of weaving or nonwoven felt to become, and utilizes the filtration of fabric to filter dusty gas, when dusty gas enters sack cleaner, large, the heavy dust of particle, because the effect of gravity settles down, fall into ash bucket, containing the gas compared with fine dusts when by filtrate, dust, by detention, makes gas be purified.It is applicable to trap tiny, dry non-fiber dust.Although this kind of dedusting method has good effect to dust collection, but cloth bag used is chemical fibre goods, because cloth bag has numerous lint hole, and cloth bag itself has certain elasticity, therefore increase dust and cohere probability in lint hole, also increase the coefficient of friction between dust and lint hole, very easily the dust formed between lint hole hardens simultaneously.Namely, when dusty gas passes through, fine dusts is easily blocked in cloth bag lint passage.Although take some measures in process of production, as installed aeration tube blowback additional in cloth bag cylinder, but because aeration tube leaves certain space distance as gas flow channel from cloth bag, and have two kinds of gases to occur in cloth bag simultaneously, a kind of be air-introduced machine gravitation, a kind of be the purge gas of aeration tube, two kinds of gas and vapor permeation together, weaken the blowback cross force of aeration tube greatly.And bag-type dust has inclined suction phenomenon, in the face of the one side dust suction of dust air-flow is many, the one side dust suction of dust air-flow is few dorsad, does not cause cloth bag internal pressure so not etc., increases and remove cloth bag dust stratification difficulty.In order to satisfied use can only strengthen the dust catching aperture of cloth bag, thus also reduce the accuracy class of interception dust.Secondly sack cleaner bad adaptability, can bake bad cloth bag when flue-gas temperature height, directly affect dust removing effects and service life.
The essential defect that above-mentioned all kinds of dedusting method exists jointly is in a word: the dust removing effects of dust removal installation all changes along with the change of extraneous condition of work, cause dust removing effects unstable, collected dust is all without after-treatment, in dust handling, transport, storage process, haze dirt, floating dust all can reappear and melt in atmosphere, cause secondary pollution.
