Abstract
The utility model aims at providing a dust removal bag for bag dust removal equipment and can overcome the defect of incomplete dust removal in the prior art. In order to fulfill the aim, the utility model adopts the technical scheme that the dust removal bag comprises a bag body; one end of the bag body is sealed, and the other end of the bag body is open; and the dust removal bag is characterized in that the bag body is a cone-shaped or frustum-shaped bag body, and the diameter of the open end of the bag body is larger than the diameter of the sealed end. After the dust removal bag adopts the technical scheme, dust attached to the bag body can sufficiently drop off by means of gravity, and in the process of spraying to remove the dust, the strength of sprayed gas flow can be kept constant basically to achieve roughly the same kinetic pressure of the spray gas flow at any position in the bag body so as to improve the dust removing effect of a dust remover and reduce the dust removal cost.
Description
Technical field
The present invention relates to a kind of dust settling pocket that is used for bag-type dust collecting equipment, relate in particular to a kind of dust settling pocket that is used for the action of low-voltage pulse bag-type dust collecting equipment.
Background technology
The dusty gas that Low-Pressure Pulse Bag Filter is mainly used in industries such as metallurgy, electric power, building materials purifies, and dust settling pocket is the core component of deduster, is directly connected to the dust removing effects of deduster.The dust settling pocket that generally uses mainly is made up of bag and bag cage at present, wherein bag is generally the not cylindrical shape cloth bag of opening (two ends equal diameter) of an end opening one end, according to the characteristic and the working condition of dusty gas, this dust settling pocket service life is greatly about 1.5-2.But development along with industry, and the raising that dedusting technology is required, the weak point of this cylindrical shape cloth bag is more and more obvious, mainly shows as: 1, dusty gas moves from bottom to top in the deduster, and enters in the cloth bag from cloth bag is suitable for reading along the cloth bag outer surface, in this process, dust is filtered at the cloth bag outer surface, for the cylindrical shape cloth bag, in its surface, below dust to top generation supporting role, make dust be difficult to come off naturally by gravity; 2, injection system is in the process of deashing winding-up, and blowing gas sprays into from the suitable for reading of cloth bag, because the sectional area of cloth bag does not reduce, and the blowing gas amount reduces gradually, the influence of resistance in addition, blowing gas its flow velocity that more down moves is low more like this, finally influences the ash-removal effect of cloth bag bottom; It is long that the cloth bag that 3 present large-scale sack cleaners use generally all is no more than 6m, and this mainly is subjected to bag influence of cage perpendicularity can not be oversize, otherwise causes cloth bag bottom gouging abrasion cloth bag easily.
Based on above-mentioned shortcoming, not only increased deduster deashing frequency, increased operating cost, and reduced the service life of dust settling pocket.
Therefore how can fully remain unchanged substantially, and then the problem of raising ash-removal effect needs to be resolved hurrily by gravity and maintenance winding-up current rate.
Summary of the invention
The utility model purpose is to provide a kind of dust settling pocket that is used for bag-type dust collecting equipment, and it can overcome the halfway defective of prior art deashing, realizes fully by gravity and the constant substantially function of maintenance winding-up current rate.
For achieving the above object, the technical solution adopted in the utility model is, a kind of dust settling pocket that is used for bag-type dust collecting equipment, include bag, this bag one end closure, an end opening is characterized in that, described bag is taper or taper type bag, and the openend diameter of described bag is greater than the sealing end diameter.
Described dust settling pocket also comprises the marsupial cage, and this bag cage is taper or taper type bag cage cooperating with taper or taper type bag, and described bag cage is arranged in the described bag.
Described taper or the big end of frustum bag cage opening are provided with fixture.
The openend of described bag is connected with bag filter tubesheet.
In order to adapt to different industry needs and different dedusting requirements, described bag can be that cloth bag can be the material densification also, and other material bag of specific function is arranged.The bag of a specific embodiment of the present utility model is a cloth bag.
After having adopted technique scheme:
1, because bag is taper, its beginning diameter is greater than the sealing end diameter, so behind the bag surface attachment dust, rely on gravity to be easy to nature and come off;
2, because bag is taper, by principle of hydrodynamics, blowing gas even there is a small amount of gas excessive, also can guarantee flow velocity, thereby realize good winding-up effect in the process of winding-up;
3, owing to being the taper bag, so be easier to change;
4, owing to use conical cloth bag, the bag diameter reduces gradually from top to bottom, causes wearing and tearing thereby avoided the bottom to collide mutually like this, and then can increase the length of cloth bag. can reduce the occupation of land of deduster.
Description of drawings
Fig. 1 the utility model dust settling pocket specific embodiment structural representation;
Fig. 2 is the structure diagram of bag-type dust collecting equipment.
The specific embodiment
In order better to understand structure function of the present utility model and characteristics, a specific embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
For helping to understand the structure and the function of the utility model dust settling pocket, below a kind of common cleaner is done simple an introduction, bag-type dust collecting equipment comprises upper box 4, middle casing 5, card 3, dust settling pocket and ash bucket.Wherein upper box 4 separates by card 3 with middle casing 5, equidistantly on the card 3 offers a plurality of holes 32 that are used to lift dust settling pocket, and the openend 11 of dust settling pocket is fixed on the card; Middle casing 5 is communicated with ash bucket, and ash bucket is connected with the dusty gas pipeline.As shown in Figure 2, dusty gas 6 enters ash bucket by gas pipeline, casing 5 in entering then, and in middle casing 5, by the filtration of dust settling pocket, the clean gas 7 turnover dust settling pocket inside after the processing enter upper box 4 by the hole on the card 32 then; The dust of staying the dust settling pocket outer surface is by the gravity effect, and perhaps regular deashing is collected in the ash bucket.
Be illustrated in figure 1 as the utility model dust settling pocket one specific embodiment structural representation, it includes bag 1, these bag 1 one ends are sealing end 12, one end is an openend 11, in the embodiment shown in fig. 1, described bag 1 is the taper type bag, and openend 11 diameters of described bag 1 are greater than sealing end 12 diameters, openend diameter D1 is 130mm, and its sealing end diameter D2 is 110mm.
As shown in Figure 1 and Figure 2, dust settling pocket described in the utility model also comprises marsupial cage 2, this bag cage 2 is a taper type, to cooperate with the taper type bag, and described bag cage (2) is arranged in the described bag (1) end that the diameter of described taper type bag cage is bigger, i.e. an end that cooperates with taper bag openend, the elastic ring that one flanging is arranged is as fixture 31, is used for openend 11 with bag 1 and is fixed in gas communication hole on the card 3.
