Abstract
The utility model relates to a front shutter inertia dust-removing device, which comprises a casing, a dust hopper, an inlet gas flue, an outlet gas flue, etc. The internal part of the front shutter inertia dust-removing device is provided with an upper shutter and a lower shutter for catching and processing the dust in the flue gas. The utility model has the characteristics of high efficiency, low resistance, and small size. When the processed gas quantity is (10-100) *10< 4 > m< 3 >/h, and the particle diameter of the powder dust is d=20 to 50 um, the dust-removing efficiency is n=65% to 80%, and the resistance delta p=200-400p< a >. The front shutter inertia dust-removing device has favorable gas flow uniformity and can be directly used as the pre-arranged dust-removing device of the large-sized dust-removing device (comprises a multi-tube dust-collecting device, an electric dust-removing running sleeve, and a bag type dust-removing device).
Description
The utility model relates to a kind of deduster of industrial fumes.
Inertial dust separator is fit to capture the dust greater than 50 μ m, and resistance is little, is the preposition deduster of using always.Conventional inertial dust separator has two big classes, but all can not be directly as the preposition deduster of the processing atmosphere scale of construction because, the first kind is the deduster that inertia combines with sedimentation, be characterized in air velocity less than 1～2m/s, bulky, separate unit is handled gas flow all less than 10
4m
3/ h, during dust size d ≈ 50 μ m, efficiency of dust collection η≤60%, resistance Δ P≤200Pa.Second class concentrates the compound deduster of forming of deduster by inertial separation inspissator and secondary, inertial separation plays a part dust is concentrated to and accounts for 10～20% and handle gas flows, concentrate this part gas of back and also will enter the secondary ash collector processing, this sharp inertia complex dust collector is when capturing d=20～50 μ m dust, efficiency of dust collection η=50～75%, resistance Δ P=600～1200Pa can reach 10 * 10 though handle gas flow
4m
3/ h, but take up an area of greatly, system complex also is not suitable for directly being used as preposition deduster.
The purpose of this utility model provides a kind of efficient, low-resistance, volume is little, can be directly as the preposition shutter inertial dust separator of the preposition deduster of large-scale deduster (comprising multi-tube dust cleaner, electric cleaner, sack cleaner etc.).
Structure of the present utility model, comprise housing, ash bucket, inlet flue duct, exhaust pass etc., it is characterized in that being provided with in the deduster one and go up shutter and a following shutter, the said shutter of going up is located at the flue gas flow direction top, the inclination angle a of its window face and horizontal plane is 0～30 °, the wide A of seam between each shutter board is 40～120mm, the angle theta of shutter board and window face
aIt is 45～20 °; Said shutter down is located at the below of flue gas flow direction, and the inclination angle b of its window face and horizontal plane is 30～50 °, and its shutter board is a sector, and the wide B of the seam between each shutter board is 80～240mm, the angle theta of the upper folding surface of sector shutter board and window face
bIt is 45～20 °.
Shutter board in the above-mentioned said shutter down can adopt angle steel to make.Used angle steel both can be equilateral, also can be unequal-sided.
Above-mentioned said upward shutter can adopt flat steel to be arranged in parallel as shutter board and form.
Above-mentioned said last shutter also can adopt angle steel to be arranged in parallel as shutter board and form, and in this case, should make its following arm of angle form corresponding shutter face, and make the angle theta that arm of angle is become with the window face under it
aScope at 45～20 °.
For flue gas can evenly, stably be flowed in the deduster, can in the air inlet flue, deflector be set.
The flue-dust retainer upper surface of the utility model bottom and the inclination angle c of horizontal plane answer 〉=60 °, to guarantee the smooth and easy ash discharge of flue-dust retainer, do not stockpile ash.
The utility model is simple in structure, has efficient, low-resistance, characteristics that volume is little, is (10～100) * 10 handling gas flow
4m
3/ h, when dust size is d=20～50 μ m, efficiency of dust collection η=65～80%, resistance Δ P=200～400Pa, its airflow homogeneity is good, can satisfy the discharge standard of increasingly stringent in the high dust concentration gas purification engineering directly as the preposition deduster of large-scale multi-tube dust cleaner, electric cleaner, sack cleaner.
Fig. 1 is a kind of structural representation of preposition shutter inertial dust separator;
Fig. 2 is the structural representation of another kind of preposition shutter inertial dust separator.
Among the figure, 1 is following shutter, and 2 is last shutter, and 3 is deflector, and 4 are the air inlet flue, and 5 for giving vent to anger flue, and 6 is flue-dust retainer, and 7 is housing.
