Description
One, technical field:
The present invention relates to environmental technology field, especially for the two bag of a kind of inside and outside filter that purifies dusty gas sleeve integral type dedusting filter bag.
Two, background technology:
At present, known purification dusty gas sees through the filter bag mode, is generally inward flow filtration-type and outside filtering type and use separately, and filter area is limited, and occupation area of equipment is big, the cost height.In order to improve the efficient of filtration, purification, major part is to adopt the method that improves the filter bag filter area, generally has two kinds: the one, increase the filter bag diameter; The 2nd, the lengthening filter bag length, so often cause equipment volume to increase, the relevant device floor space is big, the cost height, therefore, how to overcome existing inward flow filtration-type and outside filtering type and use the filter area of being brought limited separately, occupation area of equipment is big, the cost height has become the problem that presses for solution at present.
Three, summary of the invention:
The objective of the invention is situation at prior art, solution to the problems described above is proposed, use the filter area of being brought limited respectively separately at existing inward flow filtration-type and outside filtering type, occupation area of equipment is big, the problem that cost is high, design provides a kind of simple in structure, by inward flow filtration-type and the two bag of outside filtering type sleeve combined filtering, increase filter area, save the device space, equipment volume is little, saves the two bag of a kind of inside and outside filter sleeve integral type dedusting filter bag of cost.
The technical solution adopted for the present invention to solve the technical problems is: in a kind of, the two bag of outer filter sleeve integral type dedusting filter bag, the cage skeleton that comprises filter bag and support filter bag, it is characterized in that: A, the cage skeleton is made up of inner bag cage skeleton 2 and outer bag cage skeleton 1, on the outer bag cage skeleton 1, the lower end is respectively equipped with location and installation dish 13 and following location and installation dish 10, wherein, last location and installation dish 13 is provided with the installation draw-in groove 15 that cooperates installation with outer filter bag piston ring 12, following location and installation dish 10 inboards are provided with interior filter bag piston ring 19 and cooperate the installation draw-in groove of installing 18, as Fig. 1,3, shown in 4.B, filter bag is made up of interior filter bag 8 and outer filter bag 7, interior filter bag 8 and outer filter bag 7 are designed to the integral structure by last location and installation dish 13 and 10 assemblings of following location and installation dish, interior filter bag 8 is parallel to outer filter bag 7 and interior filter bag 8 tops are lower than outer filter bag 7 and interior filter bag 8 bottoms and outer filter bag 7 bottoms height together, interior filter bag 8 is supported by inner bag cage skeleton 2 and the dust 17 of dusty gas 20 is adsorbed on the interior filter bag inboard 16 of interior filter bag 8, outer filter bag 7 is supported by outer bag cage skeleton 1 and the dust 5 of dusty gas is adsorbed on the outer filter bag outside 6 of outer filter bag 7, as Fig. 1,2,4, shown in 5.
The said location and installation dish 13 of going up is provided with the outer filter bag draw-in groove 15 that cooperates installation with the outer filter bag piston ring 12 of setting on the outer filter bag 7, following location and installation dish 10 lower inside are provided with the interior filter bag piston ring 19 that is provided with interior filter bag 8 lower ends and cooperate the installation draw-in groove of installing 18, the outside, following location and installation dish 10 bottoms is provided with outer filter bag 7 lower ends and cooperates the fixedly snap ring of installing 9, shown in Fig. 1,3,4.
The course of work and the principle of present technique are: in the time of in working order, the dusty gas 20 interior filter bag inboard 16 (direction of arrow is the direction that enters outside the dusty gas 20 inside filter bags of interior filter bag inboard 16) of the outer filter bag outside 6 of filter bag 7 (direction of arrow is the direction that enters in the outside filter bag 7 of dusty gas in the outer filter bag outside 6) and interior filter bag 8 outside enters outer filter bag 7 and interior filter bag 8 filters dust (outer filter bag dust 17 and interior filter bag dust 5) 17 and 5, outer filter bag 7 outsides that are adsorbed on of the dust 17 and 5 of dusty gas like this, interior filter bag 8 inboards, clean gas 4 is by interior filter bag 8 outsides, the outer filter bag 7 inboard top blowing gas outlets that constitute clean gas space 3 are discharged.After the dust 5 and 17 in interior filter bag 8 inboards, outer filter bag 7 outsides runs up to certain thickness, resistance increases, start deashing device and carry out deashing this moment, common ash removal method is as follows: mechanical oscillation, gas tank winding-up, pulse jet, pulse rotary blowing, chamber-dividing counter-blowing, nozzle blowback etc., the deashing state generally is the opposite states when working, as shown in Figure 3.In addition, present technique is that interior filter bag 8 is parallel to outer filter bag 7 and interior filter bag 8 tops are lower than outer filter bag 7 and interior filter bag 8 bottoms and outer filter bag 7 bottoms height together, under the situation of this structure filter bag 8 filter table areas in guaranteeing increase, saves the space, makes things convenient for deashing.
The inner bag cage skeleton 2 of present technique, outer bag cage skeleton 1 adopt the metal material manufacturing, also can adopt the nonmetallic materials manufacturing, plastics (environment-protecting asepsis plastics) etc. for example, also can adopt other nonmetallic materials manufacturing etc., present technique in use, by install on auxiliary accessories such as the interior filter bag bag cage suspension bracket and inside and outside filter bag bag cage lower fixed frame respectively hook or be articulated on the dotted line hook spare of filter bag 8 tops and outer filter bag 7 bottoms (as dotted portion among Fig. 1,3,4) lift fixing.Present technique with the beneficial effect that present technology is compared is: rational in infrastructure, easy to use, cost is low, particularly interior filter bag 8 tops are lower than outer filter bag 7 and interior filter bag 8 bottoms and outer filter bag 7 bottoms height together, under the situation of this structure filter bag 8 filter table areas in guaranteeing increase, save the space, make things convenient for deashing etc.
