Abstract
An energy-saving combined dust collector consists of an inertial separator 1 and a pulse bag type dust collector 6. The inertial separator 1 comprises reversal blades, a separating plate, transverse plates and an airflow distribution plate, guide blades 2 are arranged at an air inlet on the top of the separator 1 which is wedge-shaped, lattices of the guide blades 2 are parallel to an airflow direction, the louver separating plate 3 is mounted below the guide blades, and the transverse plates 4 and the distribution plate 5 with vent holes are sequentially mounted behind the separating plate 3. After passing through the inertial separator 1 on the upstream, concentration of dust content of air containing dust is reduced by 60% at least. Dust removing cycle of a filter bag is prolonged greatly, and the service life of the filter bag can be prolonged to over 4 years. The new emission standards can be achieved without expanding specification of the dust collector and dust removing effect can not be affected by specific resistance of a dust. Further, the dust collector saves energy and reduces at least 1/4 electric consumption and about 1/5 steel consumption and space occupation compared with an electric-bag combined dust collector.
Description
Technical field
The utility model relates to a kind of novel inertia separator and the combined deduster of bag dust collector, particularly a kind of energy-conservation combined duster.
Background technology
Sack cleaner is widely used in industries such as electric power, cement, metallurgy, chemical industry at present.The basic structure of this class deduster comprises housing, filter bag, ash bucket, anti-blow cleaning dust device.In dusty gas enters from air inlet behind the air channel, dusty gas move downward from the air outlet in interior air channel rush at the ash bucket bottom, the back that collides changes the direction of motion with it.Dusty gas moves upward.The dusty gas that moves upward enters filter bag, gas passes filter bag, and dust is delayed at the filter bag surface, and dusty gas is purified.Purified gas enters exhaust zone through upper face plate and is discharged from air outlet by the air draft blower fan.Because dusty gas rushes at ash bucket and collides with it from the air outlet in interior air channel, this can make the dust of collecting in the ash bucket raise up with higher speed, in the service life that has so not only increased the load of filter bag but also made the filter bag excessive wear, reduce filter bag, the while also has a strong impact on the dust removing effects of deduster.The concentration of emission of existing deduster, most discharge standards that all can not reach new revision need to transform, conventional electric cleaner or bag dedusting area are in order to satisfy new discharge standard, can only increase the time of staying of dust during transformation at electric field, or the filter area of increase filter bag, the specification that promptly increases deduster solves.
The utility model content
The technical problems to be solved in the utility model provides that a kind of energy consumption is low, efficiency of dust collection is high and meets discharging standards, the long energy-saving combined type deduster of life of bag filter.
Solving the problems of the technologies described above the technical scheme that is adopted is: a kind of energy-saving combined type deduster, be to combine by inertia separator [1] and pulse packet deduster [6], inertia separator comprises guide vane [2], separating plate [3], transverse plate [4] and airflow-distribution board [5], it is characterized in that being provided with guide vane [2] at air inlet place, inertia separator [1] top, this blade [2] grid are parallel with airflow direction, shutter separating plate [3] is housed below guide vane, at separating plate [3] rear portion transverse plate [4] is housed successively and has the distribution grid [5] of passage.
The utility model compared with prior art has following advantage:
1, dusty gas is by behind the inertia separator of upstream, and dust content reduces by 60% at least.As the air inlet dust content is 30g/m
3(mark) is through behind the inertia separator and the dust content that enters the downstream bag dust collector will drop to 12g/m
3(mark).Because dust content greatly reduces, the cleaning cycle of filter bag can prolong greatly.As conventional bag dust collector life of bag filter is 2～3 years, and just can extend to more than 4 years the service life of this patent product filter bag;
2, owing to the dust content that enters bag dedusting area is lower, so the comparable conventional bag dust collector of the filtration velocity of design improves, according to practical experience, filtration velocity (air cloth ratio) can improve 30%～40%, reaches as high as 2.0m
3/ m
2/ min (2.0m/min), so the specification of deduster can dwindle correspondingly saves once investment.Because the quantity of filter bag reduces than conventional bag dust collector, therefore the regular maintenance expense of corresponding replacing filter bag also can decrease simultaneously.Once investment and the regular maintenance expense of newly founding the factory can reduce about 15% and 25% respectively, modernizes and expands the existing factory can reduce approximately and once invests 30%;
3, conventional electric cleaner or bag dedusting area can only increase the time of staying of dust at electric field, or increase the filter area of filter bag in order to satisfy new discharge standard during transformation, and the specification that promptly increases deduster solves.Adopt this combined duster, need not to increase the deduster specification, just can reach new discharge standard (≤50mg/m
3(mark), and efficiency of dust collection is not subjected to the influence of dust specific resistance;
4, dusty gas through inertia separator, except that playing pre-dedusting and dust cohesion effect, also helps air-flow and evenly distributes earlier, because be provided with guide plate in the blast pipe of inertia separator, air-flow tentatively evenly can be distributed;
5, this equipment is saved the energy, and power consumption is lower at least by 1/4 than electricity bag combined dust remover, and simple in structure, and steel consumption and floor space also all lack 1/5 than electricity bag combined dust remover approximately.
Description of drawings
Accompanying drawing is an overall structure schematic diagram of the present utility model.
The specific embodiment
The utility model is combined by inertia separator 1 and pulse packet deduster 6.Inertia separator is made up of parts such as guide vane 2, shutter separating plate 3, transverse plate 4 and airflow-distribution boards 5 again.Project organization is: the air inlet place is provided with guide vane 2 at wedge shape separator 1 top, and these blade grid are parallel with airflow direction; Shutter separating plate 3 is housed below guide vane, at separating plate 3 rear portions multilayer labyrinth type transverse plate 4 is housed, transverse plate and airflow direction are perpendicular, and transverse plate 4 is arranged on 3～5 layers usually, are staggered between each layer transverse plate and arrange; At multilayer transverse plate 4 rear portions airflow-distribution board 5 is set, has passage on the distribution grid 5.
When dusty gas enters inertia separator 1, at first air-flow is tentatively evenly distributed through guide vane 2, because the volumetric ratio blast pipe of separator 1 is capacious many, air velocity reduces rapidly, dusty gas and shutter separate type separator collide and change direction simultaneously, so the larger particles dust leans on the synergy of gravity and inertia force to be deposited to separator 1 bottom ash bucket 10.Dusty gas collides with transverse plate separator 4 more subsequently, and collection big dust particle at large continues sedimentation, through behind the novel inertia separator, the concentration that enters the downstream bag dust collector is reduced greatly, and is therefore very favourable to the service life of improving bag dust collector.
The dusty gas that comes out from separator enters bag dust collector through airflow distribution device.The clean gas of gas after filter bag filters enters air-purifying chamber 7, enters atmosphere through exhaust blower 8 and chimney 9 again.
The electric cleaner of the separator of this energy-saving combined type deduster upstream and electricity bag combined dust remover upstream all is the dust content that enters the downstream bag dust collector in order to reduce, and promptly plays pre-dedusting.But this energy-saving combined type deduster is saved the energy than the deduster of electricity bag combination.Because it is identical that the effect of inertial dust separator and electric cleaner is set, about 60～the 80Pa of the resistance of inertia separator, though be a bit larger tham electric cleaner, but do not need to be provided with high voltage source, so the power consumption of energy-saving combined type deduster is lower at least by 1/4 than electricity bag combined dust remover, steel consumption and floor space also lack 1/5 than electricity bag combined dust remover.
