Description

A kind of lead-acid accumulator industry purification equipment for separating lead powder from air and purification method thereof
Technical field
The present invention is the improvement to purification equipment for separating lead powder from air, particularly relates to the filtering technique that a kind of wet water membrane adds dry method high efficiency particulate air filter integral type.
Background technology
The grid casting process of lead-acid accumulator industry, can produce leaded smoke mixture, and the inside is mingled with a large amount of cork powder, machine oil, gelatine.If adopt dry cleaning technique, then oil-containing can block the ventilative filter opening of filtrate very soon containing the mixture of glue, and service life is short, at a certain temperature very easily initiation fire.
If adopt wet type water dust scrubber, purification efficiency is low, and with a certain amount of steam after water-bath, being present in deduster is liquid or gaseous state, does not reach the harsh conditions using high efficiency particulate air filter (environment must be dry).The plumbous fume purifier of Chinese patent CN201120421659.6, adopts shower nozzle spray to form water smoke, being with water rate high, being mingled with lead ion in recirculated water by making deduster in the gas finally discharged, and finally affects environmental protection tests test effect.Multiple filtration filler, when flue gas concentration is larger, particle directly blocks filler, although there is Water spray to clean, nothing
Method is thoroughly removed, and day tie the moon and tire out, the air current flow of circulation is more and more less, and packing layer is blocked, causes shorten the service life of deduster.
Besides, for realizing high-precision filtration, such as lead fume, specifies in national GB16297-1996 discharge standard, dust-laden≤0.7 milligram/cubic metre, lead-acid accumulator cleaner production relevant regulations≤0.1 milligram/cubic metre.Existing purification equipment for separating lead powder from air, adopt water film dedusting technique can to prevent fires washing flue dust, in order to ask most raising filter efficiency simply, Multi-level water film duster parallels is adopted to purify, the resistance straight line of system can be caused to increase, and it is clean finally cannot to dewater, and causes the lead ion in steam to enter air with airflow exits, affect environmental protection tests effect, be difficult to up to standard.Adopt nonaqueous dust cleaner, the greasy dirt in flue gas, gelatine cannot be overcome to the problem of media filtration micropore Severe blockage, pole fire hazardous at a certain temperature.Adopt electrostatic precipitator, the mixture of cork powder greasy dirt gelatine is bonded in electrode surface, cannot thoroughly clean up, and under certain accumulation, electrostatic attraction electrode lost efficacy, and pole fire hazardous.
Above objective phenomenon seems simple, but in the problem of polar plate of lead acid storage battery casting link release heavy metal contaminants, fails for a long time effectively to be solved, be also enough to the technical difficulty showing that people solve.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of filtrate is provided automatically to change, wet method water-bath adds lead-acid accumulator industry purification equipment for separating lead powder from air and the purification method thereof that efficiency of dust collection that dry method high efficiency particulate air filter is integrated reaches more than 99.9%, there is cooling, fire prevention, oil-stain-preventing blocking filtrate, use super high efficient filter, the advantages such as filtering accuracy is high, long service life.
The present invention for achieving the above object, provide following technical scheme: a kind of lead-acid accumulator industry purification equipment for separating lead powder from air, comprise housing, housing cavity is made up of water-bath back-fire relief room and adsorption filtration room, described water-bath back-fire relief room comprises two, the left and right chamber become by baffle for separating, described two chamber lower portion are communicated with and are marked with water bath shampoo, left chamber top offers air inlet, air inlet is connected with intake stack and stretches into the indoor chamber of water-bath back-fire relief near water bath shampoo surface, described dividing plate end is near water-bath liquid level, water-bath back-fire relief room intracavity bottom offers water inlet and bottom blow-down mouth, described right chamber is provided with dehydration deflection plate, described adsorption filtration room is made up of the one-level filtrate adsorption section be intervally arranged, active carbon section, secondary filtrate adsorption section, super high efficient filter section successively, super high efficient filter section rear portion housing offers air outlet, described dehydration deflection plate upper chambers and one-level filtrate adsorption section chamber.
As a further improvement on the present invention, one-level filtrate adsorption section is provided with filtrate apparatus for automatic change, described filtrate apparatus for automatic change comprise the drum-type handling filtering device being installed on one-level filtrate adsorption section housing both sides, the rolling filtrate be wound on drum-type handling filtering device, be close to the rolling filtrate back side support rolling steel wire link network and load and unload with drum-type the reductor that filtering device is in transmission connection.Arrange one-level filtrate after absorption is saturated by this kind, can be automatically replaced with new filtrate by mechanical device, saturated filtrate is then discharged clarifier casing.Fill rolling filtrate above the mechanical device of replacing filtrate, filtrate, under the air intake cross section of clarifier hangs, is covered with cross section, near there being steel wire transmission device after filter cloth, hold filter cloth in cross section, prevent filter cloth by the dynamic displacement of drifting of wind, can effectively prevent filter cloth from pulling apart simultaneously.Wrap-up is equipped with in the bottom of mechanical device, when automatically changing filter cloth, above puts down receipts.
As preferably, described intake stack is provided with adjustable deep bead.
As preferably, dehydration deflection plate is S type demist deflection plate.
For realizing the object of the invention, the following provide the purification method of above-mentioned lead-acid accumulator industry purification equipment for separating lead powder from air, it is characterized in that comprising the following steps: first flue gas is passed into by air inlet, by deep bead by the speeds control of airflow strikes liquid level within the scope of 5 ~ 8 meter per seconds, clash into the air-flow after the water surface with the speed impacts S type demist deflection plate of≤1.5 meter per seconds, through one-level filtrate purified gas, with the speed of≤2 meter per seconds by activated carbon filtration layer cross section, gas after activated carbon filter layer, process purification rank is the second level filtering material filter between F5-F9 again, after the frame type high efficient metre filter that the U15-U17 being finally H13-H15 or the ULPA level of HEPA level by purification circle forms, discharged by air outlet.
Beneficial effect of the present invention: purification equipment for separating lead powder from air of the present invention, traditional water bath dedusting is adopted to add the pattern of super high efficient filter, fire falls in water-bath, and the super high efficient filter that rear installs additional then can realize the purification efficiency of more than 99.9%, makes below lead ion concentration of emission≤0.1 milligram/cubic metre.The feature being different from other technique is: after filtrate absorption is saturated, directly dispelled out clarifier cavity.Absorption type filtrate is installed before super high efficient filter, the pollutants such as filter material surface adsorbed water gasoline mist.Utilize differential manometer accurate Calculation, when differential pressure reaches pre-set value, differentiate that filtrate reaches absorption saturation value, PLC interlock motor, automatic replacing filtrate, saturated filtrate is discharged in clarifier cavity, thus has manufactured the environment space of clarifier inner chamber drying, meets the condition that super high efficient filter uses.
