The deduster is characterized in that a rigid non-compression eccentric rotating interference compressing piece is used for compressing between an air-out end surface of the filter drum and an overhung pore plate; a cushion space which is not less than 30cm is reserved between the bottom of the filtering drum and the bottom plane of a filtering drum box body; and a filtering air inlet is arranged in the cushion space at the lower part of the filtering drum. According to the deduster provided by the invention, over-diameter particles are ensured not to exist in the filtered gas, the filtering material is prevented from being damaged effectively, the service life of the filtering drum is prolonged, two main defects which are hard to solve by a traditional filtering drum deduster are solved completely, and the effective service life of the filtering drum is prolonged from originally maximum twelve months to eighteen months. A frame type filter is added above a filtering drum air outlet by being connected with a transition section interval, the filter precision of the frame type filter is higher than the filter grade of the lower filtering drum, thereby forming secondary filtration of upper and lower inter-phase serial connection; the minimum filtering precision can be 0.1 microns; the filter drum deduster provided by the invention can be used in the lead-acid battery industry for filtering lead dust and fume, and the dust content of the filtered gas is not more than 0.07mg/m<3>, which is far less than the national emission standard; the filtration resistance is increased by more or less than 10% on the basis of previous grade, so that the contradiction between the filtering precision and the filtering resistance is balanced well.
Description
Technical field
The present invention is the improvement to filter cartridge dust remover, relates in particular to a kind of filter cylinder and does not leak out with the installation orifice plate, and filtering accuracy can reach the filter material precision, the filter cartridge dust remover of filter cylinder long service life.
Background technology
The dust removal by filtration that contains fine dirt gas, a kind of mode through the filtration of filter cylinder filter material, makes dust granules be trapped within filter cylinder filter material appearance for adopting the outside filtering type filter cartridge dust remover, and pure air then passes the filter cylinder filter material, thereby reaches catharsis.For satisfying safeguarding and replaceability of filter cylinder, usually with the movable assembled of cartridge design one-tenth, promptly filter cylinder adopts with fixing suspention filter cylinder orifice plate (vertically placed type) and flexibly connects in actual design.Yet in actual motion, an objective phenomenon, deduster always contains the micronic dust of particle diameter greater than filter cylinder aperture of filter material (precision) in the filtration treatment gas after operation a period of time, makes actual treatment be difficult to reach designing requirement.The applicant is on substantive test, analysis foundation for this reason; Think to use after a period of time and have the micronic dust that surpasses filter screen precision (hole) in the gas of filter back; Main cause has two: one, and the dusty gas filtration treatment is that big air quantity, high flow rate filter; The movable assembling between filter cylinder end face and orifice plate may particularly be moved and repeatedly dismantle and unavoidably can reduce sealing in vibration for a long time because of seal failure causes leaking out, and causing the generation of leaking out to exceed standard; The 2nd, existing filter cartridge dust remover; Air inlet is over against filter cylinder; Airduct filtered air directly high speed (air velocity duct is up to 11 meter per seconds) directly impacts the thin filter medium (wood pulp cellulose filter paper) of filter cylinder, and dust granules dirt high speed impact very easily causes the punch through damage to filter material, not only influences filtering accuracy; And cause the actual Acceptable life of filter cylinder to shorten, general common had only about 10-12 month.Therefore filtration exceeds standard and filter cylinder weak point in service life, becomes the two big shortcomings that existing filter cartridge dust remover is difficult to overcome.
Existing filter cartridge dust remover; Though sealing between assembling filter cylinder end face and suspention orifice plate was proposed to improve; But all continue to use the unique employing compressible elastomeric of usual thinking and compress (compression) sealing; Chinese patent CN200951368 filter cylinder fixture for example, being provided with section between filter cylinder rectangle air outlet and the framework grid is the sealing channel-section steel of U-shaped, pad has asbestos board between U-shaped sealing channel-section steel and the rectangle air outlet.Chinese patent CN2655993 filter cylinder syndeton, the filter cylinder port seals flexible the connection through expansion pad with filter cylinder port and the formation all around of orifice plate aperture.Chinese patent CN2204190 cartridge type filter screen deduster, casing are installed the interior cartridge clip positioner that is provided with along the duct of filter cylinder circular hole.Yet because filter cylinder filtration work; Receive bigger vibration impulsive force (for example impact of high flow rate filtered airflow and compressed air are to the filter cylinder jetting deashing) for a long time, above-mentioned elastic compression compresses seal approach and still is difficult to avoid sealing the lax inefficacy of fatigability, the for example expendable compression of meeting generation after asbestos board and the expansion pad time length; Cartridge clip also can receive the tired spring force that reduces to cause loosening easily; Therefore adopt the new equipment treatment effect of this type of sealing better, then occur filter dirt after use a period of time and exceed standard, it is simple that this problem seems; But fail for a long time effectively to be solved, become and be difficult to the obstacle gone beyond in the industry.
Secondly, existing filter cartridge dust remover, filter cylinder blowback flushing all adopts a pulse valve to control a single filter cylinder winding-up regeneration a plurality of arranged side by side of not having simultaneously.The loss factor of gas in pipeline that objectively exists ignored in this design, causes that each nozzle ejection pressure is actual can not evenly to produce each filter cylinder ash-removal effect difference thus, influences the effective filtration area behind the deashing; Add that electrically-controlled valve relatively easily damages, a plurality of filter cylinders are concentrated valve control reverse gas cleaning to cause a valve to damage a plurality of filter cylinders of influence and are lost the reverse gas cleaning function, cause the filter cylinder dust stratification to can not get timely cleaning, lose the filter cylinder filter efficacy.And the filter cylinder deashing is not thorough, also can influence the filter cylinder Acceptable life, and therefore existing filter cylinder is short service life, and also factor is relevant therewith.In addition; Have the jet deashing of blowback now, give vent to anger for valve nozzle and directly directly blow at a high speed, valve nozzle is given vent to anger and is directly jetted; The less relatively filter cylinder top of causing of angle of flare can not get effective deashing regeneration; Also reduce the actual treatment effective area, drawn back nozzle and filter cylinder distance and can cause distance winding-up power and tolerance deficiency again, reduced ash-removal effect.Also have, existing control winding-up pulse valve is arranged on the unit outside, and it is big that winding-up produces noise, forms the secondary noise pollution.
Besides, for realizing that high accuracy filters, for example lead dust, lead fume, discharging standards dust-laden≤0.7mg/m
3, existing filter cartridge dust remover is for realizing the high accuracy filtration, pursue simply that improving filter cylinder filter material precision meets the demands.Yet single pursuit filter material high accuracy can cause the filtration resistance straight line to increase (the more former rank of resistance increases 30-40% usually), thereby cause operation energy consumption to increase considerably.The particularly existing wood pulp cellulose filter paper that adopts usually; Be used for battery industry system lead powder and produce the dusty gas processing,, and keep certain moisture because of lead powder uses the dilute sulfuric acid immersion in the mill and adds other additive; Make that wearing into fine powder has certain cohesiveness; Filtration treatment very easily sticks to filter material surface, and the difficult removing in bonding back, influences filter capacity; Wood pulp cellulose filter paper is filtered into layer and filters; Particle diameter unavoidably can take place about equally or be slightly less than the aperture particle and pierce, and be difficult to go out through reverse gas cleaning in high-rate fitration gas shock filter material; Also can cause the part filter opening to stop up for a long time, this also influences the filter material Acceptable life.
Above-mentioned objective phenomenon seems simply, but fails effectively to be solved in the filter cylinder dedusting midium or long term, also is enough to the technical difficulty that shows that people solve.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned prior art, a kind of filter cylinder is provided and orifice plate is installed is not leaked out, and filtering accuracy can be stablized and reaches the filter material precision, the filter cartridge dust remover of filter cylinder long service life.
Another purpose of the present invention is to provide a kind of reverse gas cleaning effective, can prolong the filter cylinder filter cartridge dust remover in service life.
It is little that still a further object of the present invention is to provide a kind of filter cylinder to attach dirt, and reverse gas cleaning is thorough, and the filter cylinder long service life is specially adapted to contain the filter cartridge dust remover of wet dirt gas filtration.
Another object of the present invention is to provide a kind of filtering accuracy high, and the relatively little filter cartridge dust remover of filtration resistance.
The present invention's first purpose realizes; Mainly improving one is vertically to hang tube filter cylinder end face and suspending in midair and fixedly adopt rigidity not have the eccentric rotary of compression interference compressing structure between orifice plate; The 2nd, set up the air inlet cushion space in the filter cylinder bottom; The filtering inlet air mouth is arranged on cushion space, fixedly is prone between orifice plate leak out thereby overcome prior art filter cylinder end face and suspend in midair, and handles the direct at a high speed impact filter cylinder of gas surface and cause puncture; Cause to occur oversize micronic dust and filter cylinder two short big long-term existing problems of service life in the gas of filter back, realize goal of the invention.Specifically; Filter cartridge dust remover of the present invention comprises the filter cylinder casing of bringing air port and air outlet into, and is interior by suspention orifice plate assembling suspention alternate some air-out filter cylinders of vertically installing arranged side by side; The reverse gas cleaning nozzle of filter cylinder outlet top; It is characterized in that having between filter cylinder air-out end face and suspention orifice plate rigidity not have compression eccentric rotary interference compressing member and compress, there is the cushion space that is not less than 30cm the filter cylinder bottom with the filter cylinder tank floor, and the filtering inlet air mouth is arranged on filter cylinder bottom cushion space.
The present invention's second purpose realizes; The main improvement is that each filter cylinder top reverse gas cleaning nozzle respectively has independently electrically-controlled valve control; An i.e. nozzle one valve; Thereby avoid the shared electrically-controlled valve control of a plurality of blowback nozzles reverse gas cleaning, cause each filter cylinder deashing difference, and a valve damages the shortcoming that influences other a plurality of filter cylinder deashing regeneration.
The present invention's the 3rd purpose realizes, mainly improves the filter cylinder filter material and adopts the overlay film filter material that at least simultaneously is covered with the high molecule micropore film, and for example fiber filter paper simultaneously is covered with the overlay film filter material of PTFE polyester perforated membrane.Thereby filter material is filtered by original filter paper layer, become the overlay film facial mask and filter, not only strengthened surface of filter medium intensity, make filter material be difficult for being processed micronic dust puncture in the gas, also make the filtration micronic dust pierce the filter material probability and significantly reduce; And overlay film makes the filter filter material adhere to micronic dust to reduce greatly, the particularly adhesion of wet dust, and both reverse gas cleaning effects that have been significantly increased make that the filter material deashing is more thorough.These all help the prolongation of filter material Acceptable life, and reduce filter paper puncture probability greatly.
The present invention's the 4th purpose realizes; Main improve be perpendicular put above the filter cylinder air outlet through connect changeover portion at interval (blowback nozzle top) have filtering accuracy to be higher than second filter box of bottom filter cylinder filtration grade, the box filter of the screen pack H13-H15 of built-in HEPA level or ULPA level screen pack U15-U16 composition.Thereby the secondary different accuracy that forms vertical alternate serial connection filters; Make filter become before (descend) thick back carefully (on) double-filtration; Not only satisfied some high accuracy and filtered, and adopted cascade filtration obviously to reduce the filtration drag overall, better balanced filtering accuracy and filtration resistance contradiction.
Among the present invention.
Between filter cylinder end face and suspention orifice plate, and between frame-type filter and installation frame, adopt rigidity not have compression eccentric rotary interference compressing member and compress, for the present invention solves the measure that is different from usual thinking (elastic compression sealing) that the permanently effective sealing of assembled end is taked.Rigidity does not have the compressibility distortion, can guarantee to use for a long time no any fatigability loose; Eccentric rotary can realize rigidity do not have the compression interference compress; For example the magnitude of interference is enough to make the combination end face; For example the filter cylinder end face with or install to still have after the original flexible gasket of end face compresses fully and can compress the magnitude of interference, reaches long-term use with this and do not leak out, and eccentric rotary compresses; Can not turn round to make to compress to produce and become flexible, can guarantee that assembled end fully compresses sealing because of vibration.The eccentric rotary hold down gag for example can be cross section eccentric wheel or axle, cross section elliptic wheel or axle, and their distortion, and rotation eccentric wheel that the two steel axles that for example link into an integrated entity are side by side formed or axle, its offset is and compresses the magnitude of interference.Do not have compression eccentric rotary interference compressing member, can be arranged between the connection both ends of the surface, can be arranged at an end face pushing tow yet and compress, from easy mounting structure, the interference compressing member, a kind of being preferably adopts the pushing tow ascending manner to compress.
Be not less than the cushion space of 30cm at the bottom of filter cylinder bottom and the casing, make filtering inlet air be able to buffer deceleration, both avoided handling the direct high speed impact filter cylinder of dust granules surface in the air intake, cause that the filter cylinder filtrate damages; Because of reducing, filtering velocity makes that filtering the time of staying prolongs, and has also promoted the filter effect raising again.Filter cylinder bottom cushion space height, test is preferably 30-100cm, and promptly the filter element casing is vertically highly greater than filter cylinder height 30-100cm (not comprising bottom flue-dust retainer and feet); Promptly have above-mentioned technique effect,, then can increase the volume and the cost of equipment if increase too much; And the non-linear relation of raising effect; Therefore do not have this necessity, but do not represent to exceed 100cm cannot, proposing that the upper limit places restrictions on only is the preferable selection of considering from economy.
Overlay film filter material, its base material are prior art filter cylinder filter material, for example fiber filter paper; Only be its at least one side (filtering the outside) pass through film mulching method; Compound one deck high molecule micropore film, its macromolecular material only need to select from economy and porous film forming, all can be used for overlay film as long as can form the high molecular film material of micropore; Its film mulching method also can adopt prior art, and the film mulching method of for example weaving is manufactured.The results showed, be best with PTFE polyester film performance especially wherein.
Filter cylinder top filtering accuracy is higher than the frame-type filter of bottom filter cylinder filtration grade; Its filter element filter screen can adopt the screen pack H13-H15 (0.3 micron of filtering accuracy, filter efficiency 99.9-99.999%) or the ULPA level screen pack U15-U16 (0.1 micron of filtering accuracy, filter efficiency 99.9995-99.999995%) of commercial for example HEPA level; Main cascade filtration with the filtering accuracy requirements at the higher level; And, reduce the overall operation resistance through thickness two filtrations, improve filter efficiency.
In addition.
The filter cylinder box back surface also can be provided with outstanding air intake linkage section; For example U-shaped or arc air intake linkage section, its main effect has two: one, helps the filtering inlet air switching-over and forms cyclonic current, further air intake is played cushioning effect; Avoid directly impacting the surperficial filter paper of filter cylinder; Two can simplify with the external air inlet pipeline and are connected, and for example can pass through vertical air intake, reduce the outer blast pipe that connects and take up room.
Can also have in the installation of the aperture of being close in suspention filter cylinder orifice plate suspention each aperture, filter cylinder opposite; The bottom bore is with the Venturi tube (venturi) in aperture; On the filter cylinder air outlet, under the blowback nozzle, set up Venturi tube and can play two effects: the one, set up and can make behind the Venturi tube when deashing winding-up high velocity air passes Venturi tube, under venturi action, can bring the more air in outside into; For example induce the 5-8 air supply of doubly jetting, thereby several times have increased filter cylinder deashing winding-up tolerance; The 2nd, penetrate the air-flow angle of divergence through Venturi tube and increase; Make filter cylinder topmost section also can obtain effective reverse gas cleaning; Reduced filter cylinder deashing winding-up dead angle, top, two big effects make that the regeneration of filter cylinder deashing is more thorough, better effects if; Not only improved the filter cylinder filter efficiency, and because deashing thoroughly also can prolong the filter cylinder Acceptable life.Suspention filter cylinder orifice plate is close in the Venturi tube lower end, upper end and blowback injector spacing, and test is preferably 10-15cm, the too small induced air amount that then influences of spacing, the excessive blowback winding-up power that then can weaken of spacing influences ash-removal effect.Though corresponding blowback nozzle and the filter cylinder apical side height (increasing by a Venturi tube height) of having increased owing to increase the air capacity that Venturi tube has increased the deashing blowback greatly, far can be offset because of nozzle and raise the deficiency that influences jetting deashing.
Vertical suspention filter cylinder; Each cartridge wall spacing test is preferably 15-35cm; Usually, filter cylinder dedusting filter cylinder spacing increases; Filter cylinder attaches dirt and comes off and fly to adjacent filter cylinder in the time of can effectively avoiding filter cylinder to replace reverse gas cleaning, thereby the mutual infection when having avoided that filter cylinder replaces deashing one by one makes that deashing regeneration is more thorough.
The technical staff should be understood that and understands; The said numerical value of this patent be not requirement be that exact value could be realized basic effect on the mathematics; It is a kind of preferable interval of the present invention's test; Depart from this interval value and just do not represent and can not realize basic function of the present invention, therefore suitably deviation still should belong to this patent category.
Filter cartridge dust remover of the present invention, with respect to prior art, it is big not only to have kept the perpendicular filter cylinder filter area of putting; Deashing is advantage completely, and compresses (not adopting compressible strain part to compress) because filter cylinder air-out end face and orifice plate assembling adopt rigidity not have compression eccentric rotary interference compressing member, and rigidity does not have compression; Can not produce any compressibility distortion, there is the magnitude of interference in eccentric rotary, even repeatedly dismounting; Can not cause to compress yet and the gap occur; Compress sealing lastingly thereby guarantee to need sealing surface (for example filter cylinder air-out end face with between suspention orifice plate) to have, can be in long-term the use and repeatedly assemble because of vibration, produce irreversible compression and produce seal clearance and cause and leak out.The filter cylinder bottom increases the air intake buffering, and air inlet is arranged on breeze way, not only can avoid pipeline high wind speed (for example 11 meter per seconds) dust directly to impact filter cylinder filter paper; Cause damage, and increase buffering area, make the filter box spatial volume increase filter paper; Making filter cylinder filter filtering velocity is able to descend; For example drop to below 0.74 meter/minute by former 1.2 meters/minute, the dust time of staying prolongs, the also corresponding raising of purification efficiency; This external air inlet buffering area is provided with; Some relatively large granule dusts are through high velocity impacts and after cushioning in the also feasible processing gas; Direct natural subsidence is separated under the self gravitation effect, has also alleviated filter cylinder filtration, purification load, and this has all weakened the punch through damage of dust granules to the filter cylinder filter material greatly.Aforementioned binomial measure can be guaranteed no oversize particle in the filtering gas, effectively protects filter material not to be damaged, and prolongs filter cylinder service life, thereby has thoroughly solved the two big shortcomings that filter cartridge dust remover is difficult to overcome.Secondly, each back-flushing soot-cleaning nozzle adopts independently electrically-controlled valve (filter cylinder one valve), each filter cylinder deashing indifference; High conformity; And valve damages and can not influence other filter cylinder deashing regeneration, and overall deashing favorable regeneration effect has also improved filter efficiency and service life.The filter cylinder filter material adopts the surface to be covered with the compound overlay film filter material of macromolecular material microporous barrier; Filter material is filtered by original filter paper layer; Become the overlay film facial mask and filter, not only strengthened surface of filter medium intensity, filter material is difficult for being processed micronic dust puncture in the gas; Also make the filtration micronic dust pierce the filter material probability and significantly reduce, also help deashing regeneration thoroughly; Simultaneously overlay film makes filter filter material micronic dust adhere to greatly to reduce, the particularly adhesion of wet dust, and both reverse gas cleaning effects that have been significantly increased make that the filter material deashing is more thorough.These also all help the prolongation of filter material Acceptable life, and reduce filter paper puncture probability greatly.Set up Venturi tube on blowback nozzle below, the orifice plate face, can not only bring the more air in outside (for example induce 5-8 doubly jet air supply) into and carry out jetting deashing, increased winding-up recoil air capacity greatly; Make deashing more thorough; Also help prolonging filter cylinder service life, and Venturi tube also enlarged the angle of divergence of ejection air-flow, can be to the recoil of jetting of filter cylinder top; Realize no dead angle reverse gas cleaning, guarantee that the filter cylinder gross area filters.Besides; The perpendicular filter cylinder air outlet top of putting increases the frame-type filter that filtering accuracy is higher than bottom filter cylinder filtration grade at interval through connecting changeover portion; (descending) thick back before filtration becomes (on) thin double-filtration, not only having satisfied some high accuracy and filtered, minimum filtering accuracy can reach 0.1 micron; Be used for the lead-acid accumulator industry, filter lead dust, lead fume filtration back gas dust-laden≤0.07mg/m
3, well below discharging standards, and adopt the cascade filtration of vertical alternate serial connection, obviously reduced the filtration drag overall, same treatment precision, filtration resistance are only increasing about 10% on the prime basis, better balanced filtering accuracy and filtration resistance contradiction.Middle air-out connects the transition casing, makes filter cylinder blowback nozzle be arranged in the casing of sealing, has externally also alleviated the compressed air spraying deashing and has produced noise, has avoided the noise secondary pollution.The filter cylinder spacing increases, and filter cylinder attaches dirt and comes off and fly to adjacent filter cylinder in the time of can effectively avoiding filter cylinder to replace reverse gas cleaning, thereby the mutual infection when having avoided that filter cylinder replaces deashing one by one makes that deashing regeneration is more thorough.Above-mentioned resultant effect, laboratory test make the filter cylinder Acceptable life bring up to 18 months by original maximum 12 months, and can guarantee that error-free running period inner filtration gas dust-laden does not exceed standard.
Optimize specific embodiment below in conjunction with two; Essence of the present invention is further understood in exemplary illustration and help; But the embodiment detail only is in order the present invention to be described, not to represent the present invention to conceive whole technical schemes down, therefore should not be construed as the total technical scheme of the present invention to be limited; Some are In the view of the technical staff; The unsubstantiality that does not depart from the present invention's design increases and/or change, and for example simple the change or replacement of technical characterictic to have same or similar technique effect all belongs to protection domain of the present invention.
