Description
Technical field
The utility model relates to a kind of slag micropowder bag dust collector.
Background technology
Slag is the waste residue that steel mill discharges, and slag micropowder can equivalent substitution cement after levigate, not only environmental protection but also can produce considerable economic benefit.Because the thin many (420-470m of raw material powder of the fineness ratio cement flour of slag micropowder and preparation cement
2/ kg), water content is big, moisture content is high, the dust that filters on filter bag is difficult to peel off, adopt conventional in the past bag dust collector running resistance height (＞1700Pa), system's power consumption height, life-span of the filter bag generally is lower than 2 years.
Summary of the invention
The purpose of this utility model is to provide that a kind of running resistance is low, life-span of the filter bag is long, the lower slag micropowder bag dust collector of outlet concentration of emission.
Its technical scheme is: a kind of slag micropowder bag dust collector, comprise the casing of being with ash bucket, be arranged on a plurality of bags of chambers that constitute by card, filter bag and chamber dividing plate in the casing, by the air channel dividing plate constitute into and out of the air channel, form air-purifying chamber between roof box and the card, the deashing device of each bag chamber is made of the off-line valve plate of lift valve and lift valve control and the pulse valve that is arranged on the air-purifying chamber both sides of top, each bag chamber, it is characterized in that: filter bag adopts the acrylic filter bag of anti-hydrolysis, and its outer surface adopts the PTFE overlay film; The outside of casing and ash bucket is provided with heat-insulation layer, and the inboard of top inspection door is provided with heat-insulation layer; Ash conveying device under the ash bucket adopts air conveyer flume, and unloading valve adopts unpowered three road Weight type reprint valves.
Its technique effect and advantage: the utility model is at the characteristic of slag micropowder, and structural design is crossed the flow velocity at each position to reduce air communication to greatest extent, improved the inertial settling amount of dust, reduces filter bag dust adsorbance is principle.Card upper space air-purifying chamber horizontal gas flow speed＜8m/s, off-line valve plate lower stream of airflow speed＜6m/s, the wind speed＜6m/s of air outlet under the valve plate, the air velocity＜10m/s in turnover air channel.According to above-mentioned parameter, go out the different slag micropowder bag dust collector of size according to the different designs of air quantity.According to characteristic according to slag micropowder " moisture content height, the dust fineness is thin, dust content is high ", each spot size that the deduster internal gas flow passes through is according to the air velocity design of setting, rational in infrastructure, the deduster structural drag is low, the inertial settling that helps big dust particle reduces dust adsorbance on the filter bag.Owing to adopt acrylic overlay film filter bag, prevent the hydrolysis broken bag, lower filtration resistance is arranged again.Each position INSULATION DESIGN of deduster has been avoided dewfall lake bag.Ash bucket adopts down air conveyer flume, and it is big to unload grey ability, the wearing and tearing of having avoided adopting the ash conveying device of other form to cause.Device for discharging adopts unpowered three road weighted valves, and lock wind is effective, saves power consumption, discharging amount and unload grey frequency and can and adjust arbitrarily by the adjusting of weight position.Practical application shows, " slag micropowder bag dust collector " advantage highly significant is compared with other bag dust collector of air quantity with same specification, and technical-economic index holds a safe lead, complete machine running resistance 600-1000Pa, outlet discharging＜25mg/nm
3, the system fan power consumption can save 30%, and life-span of the filter bag can be above 3 years.Can be used for the collection of steel mill, cement plant slag milling system product and gather dust.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the side view of Fig. 1.
The specific embodiment
As shown in Figure 1, the slag micropowder bag dust collector, comprise the casing 3 of being with ash bucket 2, be arranged on a plurality of bags of chambers 11 that constitute by card 8, filter bag 4 and chamber dividing plate 15 in the casing, by air channel dividing plate 13 constitute into and out of the air channel, the air-purifying chamber that forms between roof box and the card, the deashing device of each bag chamber is made of the off-line valve plate 9 of lift valve 10 and lift valve control and the pulse valve 6,7 that is arranged on the air-purifying chamber both sides of top, each bag chamber.
Because the slag water content is big, moisture content is high, the external thermal insulation of deduster casing 3 and 100 millimeters thickness of ash bucket 2 designs, the inner thermal insulating layer of 50 millimeters thickness of top inspection door design prevents the inner dusty gas dewfall of deduster.For preventing filter bag 4 hydrolysis broken bags, adopt the acrylic filter bag of anti-hydrolysis.Because the slag micropowder fineness is thin, the filter bag outer surface adopts the PTFE overlay film again, prevents that fine dusts from entering obstruction filter bag in the filter bag fiber hole and influencing the filter bag gas permeability, adopt PTFE overlay film filter bag, dust is easy to peel off, and can keep filter bag gas permeability and strainability preferably, and running resistance is low.
Because the Dust Capacity of slag micropowder is big, grindability is poor, and the ash conveying device under the ash bucket adopts air conveyer flume 16, and unloading valve 1 adopts unpowered three road Weight type reprint valves, and this valve unloading ash capacity is big, and lock wind is effective, and non-power consumption.The weight Position Design becomes adjustable, unloading performance and unload grey frequency and can adjust by the adjusting of weight position.
Its operation principle: when dusty gas enters ash bucket by blast pipe, oarse-grained dust is here because gravity and inertial collision at first fall into ash bucket, played the effect of gathering dust in advance, all the other thinner dust along with air-flow after filter bag filters, dust is delayed at the outer surface of filter bag, purified gas enters exhaust duct via air-purifying chamber, off-line valve plate hole, enters atmosphere by blower fan then, thereby has reached the purification purpose.Along with constantly carrying out of filtering, dust attached to the filter bag outside constantly thickens, the resistance of dust-precipitator also constantly rises, when resistance reaches certain value, need dust-precipitator is carried out deashing, at this moment, controller sends instruction to " pulse dust cleaning system ", at first, first bag of chamber off-line valve plate closed, and two pulse valves are opened (0.15 second) simultaneously about this bag chamber, spray the compressed air of 0.35-0.45Mpa to air-purifying chamber space, card top, compressed air moment enters filter bag inside, makes the filter bag vibrations, blow-up, the dust that accumulates in the filter bag outer surface is stripped from, fall into ash bucket, after 4 seconds, reopen the off-line valve plate of first Room, first Room enters the filtration state once more; Deashing is carried out by said process successively in each chamber, so circulation.The soot cleaning system operating frequency is adjusted according to the dust remover resistance situation.
