According to the device, the cyclone dust remover is adopted to filter large-particle dust, is high in dust removal efficiency and achieves the purpose of pre-removal; the backward-stage porous plate dust remover collects fine dust and is high in dust removal efficiency; the smoke emission concentration is low; and the device is low in investment and operation energy consumption and good in purification effect.
Description
Technical field
The utility model relates to casting industry cleaning grinding dust removing device, and particularly a kind of micro-filtration filter of administering casting cleaning polishing PM2.5 micronic dust belongs to the flue gas ash removal technical field.
Background technology
The casting cleaning grinding dust removing device is that fume trap cover, sack cleaner, air-introduced machine, aiutage connect successively by pipeline in the prior art, produce metal iron filings and emery wheel bits etc. in the casting cleaning bruting process and mix dust, under the suction function of blower fan after fume trap cover captures, enter sack cleaner via pipeline, enter atmosphere through blower fan by aiutage after the filtration.Because dust removal installation adopts sack cleaner in the device, the dust removing effects that mixes fine solid particle for metal iron filings and emery wheel bits etc. is very undesirable, the dust that is retained down forms filter cake on the cloth bag surface, hardened in the cloth bag surface, cause and stick with paste bag, deduster running resistance height, the air-introduced machine energy consumption is big, even deduster can't run well; Because the pore size filter of cloth bag can't be finished filtration work for particle diameter smaller or equal to the fine solid particle of 2.5 microns (PM2.5) more than 30 microns, discharging enters atmosphere, enters to human lung's deposition by respiratory tract, and health is worked the mischief.
Summary of the invention
At the problems referred to above, the utility model provides a kind of micro-filtration filter of administering casting cleaning polishing PM2.5 micronic dust, for particle diameter is low smaller or equal to fine solid particle good dedusting effect, the concentration of emission of 2.5 microns (PM2.5), running resistance is low.
The technical solution of the utility model is: a kind of micro-filtration filter of administering casting cleaning polishing PM2.5 micronic dust, comprise fume trap cover, cyclone dust collectors, sintered plate deduster, main air blower, aiutage, it is characterized in that: described fume trap cover is by pipeline be linked in sequence cyclone dust collectors, sintered plate deduster, main air blower, aiutage.
The beneficial effects of the utility model are: cyclone dust collectors filter big dust particle, the efficiency of dust collection height, collect 95% Dust Capacity, reach the purpose of pre-dedusting, back level sintered plate deduster is collected fine solid particle, because the sintered plate filter core has 0.03～0.3 micron pore size filter, be 99.99% for particle diameter smaller or equal to the fine solid particle efficiency of dust collection of 2.5 microns (PM2.5), for the dust more than 0.1 micron, efficiency of dust collection is 99%, guarantee the low concentration discharging, the device running resistance is low, reduced system's operation energy consumption, system's main air blower total head is low, power of motor reduces, the plant investment expense is low, maintenance cost is low, plant area is economized, concentration of emission is low, can guarantee to discharge dust concentration 2mg/Nm

Advantage of the present utility model is:
1, dedusting precision height: the sintered plate filter core has 0.03～0.3 micron pore size filter, and for the fine solid particle of particle diameter smaller or equal to 2.5 microns (PM2.5), efficiency of dust collection is 99.99%, and for the dust more than 0.1 micron, efficiency of dust collection is 99%;
2, sintered plate deduster filter area is big: the wave-shape design of sintered plate filtering surface, the filter area in equal volume are 3～6 times of filter bag;
3, the self-cleaning ability is strong: the structure of rigidity, and make purge gas more directly act on the powder that is attached to filtering surface, there is not the existence of buffering, ash-removal effect is thorough;
4, hydrophobic, oleophobic: the sintered plate matrix is formed by the different macromolecular material sintering of multiple density, and the PTFE coating deeply also forms ultra-fine micropore resistance to bond structure with it to sintered plate matrix hole, have the hydrophobic oleophobic performance;
5, acidproof, alkaline-resisting ability is strong: the special resins material, can stand the long term high temperature corrosion of strong acid, highly basic;
6, the service life of overlength: higher intensity and toughness, can stand the repeated stock of several thousand times gases at high pressure every day, its anti-wear performance is more than 4 times of iron and steel, and superpower acid and alkali-resistance ability and perfect self-cleaning effect are arranged again, makes can reach more than 10 years the service life of sintered plate;
7, constant pressure, resistance is stable: uniform micron order aperture, make dust can only be attached to the filter course surface, thereby it is unimpeded fully that the filter course inner passage almost still keeps, simultaneously, filter cake is removed thoroughly during blowback, and then when long-time running, it is constant to show as filter pressure, and running resistance is stable;
8, convenient maintenance and replacement is quick.
Description of drawings
Fig. 1 is device structure schematic diagram of the present utility model.
Among the figure, 1. fume trap cover, 2. cyclone dust collectors, 3. sintered plate deduster, 4. main air blower, 5. aiutage.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
A kind of micro-filtration filter of administering casting cleaning polishing PM2.5 micronic dust in the utility model, comprise fume trap cover 1, cyclone dust collectors 2, sintered plate deduster 3, main air blower 4, aiutage 5, it is characterized in that: described fume trap cover 1 is by pipeline be linked in sequence cyclone dust collectors 2, sintered plate deduster 3, main air blower 4, aiutage 5.
The course of work of the present utility model is: be example to produce ￠ 1500mm valve casting cleaning polishing dust collecting process, as flow 10000Nm
3/ h, 40 ℃ of temperature, dust content 7g/Nm
3Metal iron filings and emery wheel bits etc. mix dust, enter fume trap cover 1, are transported to cyclone dust collectors 2 through piping, cyclone dust collectors 2 filter big dust particle, and efficiency of dust collection is 95%, reaches the purpose of pre-dedusting, through sintered plate deduster 3, dust content is 2mg/Nm after sintered plate deduster 3 purifies again
3, be pressed into aiutage 5 through pipeline by main air blower 4 and enter atmosphere.
