Abstract
The utility model relates to a frame-supported dedusting frame of ejector, which comprises a frame 1 and an ejector 2. The utility model is characterized in that a plurality of upright ribs 4 are fixedly connected above a bag cage opening 3 of the frame 1; the upright rib 4 is fixedly connected with an ejector (2), the upright rib 4 is integrated with the vertical rib 5 of the frame 1 and is the extended part of the vertical rib 5. The utility model solves the contradiction between resistance and dust-cleaning requirement, and also reduces the resistance that the induced airflow enters the interior of sack from the assembly opening of the sack and the frame twice, because of spacial increment, the dust-cleaning airflow amount in the sack is also increased, on the one hand, the dust-cleaning effect is ensure to be more thorough, on the other hand, under the same effect required by the design, compression air consumption can be saved, thereby saving energy.
Description
Affiliated technical field
The utility model belongs to a kind of deduster parts, is a kind of skeleton of fiber bag precipitator particularly.
Background technology
In the prior art, skeleton is used for supporting cloth bag as the vitals of fiber bag precipitator, to guarantee cloth bag inside sufficient space is arranged.The outside of cloth bag is a dusty gas; after dusty gas becomes clean gas after by the cloth bag surface filtration that is supported by skeleton; enter the inner space of cloth bag; make air-flow flow to the general assembly mouth that skeleton mouth and cloth sack are combined to form by this space; by air-introduced machine the purified gas extraction is entered atmosphere; thereby realize purifying flue gas, the purpose of protection environment.When the dust on cloth bag surface reached certain thickness, the resistance of cloth bag will be increased to very big, and air-flow just can not pass through cloth bag smoothly, at this moment just need implement deashing to cloth bag.Compressed air system provides the momentary pulse air flow stream of coming to enter the cloth bag inner space that skeleton supports with very high speed by the skeleton mouth, the vibrations of formation impact, induce several times secondary gas flow to enter cloth bag inside simultaneously by sack, air-flow externally expands, make originally being in the cloth bag of taking out under the flat state under the blower fan negative pressure and outwards heave distortion, shake off to be attached to the dust on cloth bag surface by vibrations and distortion, recover the filtering function of cloth bag.Because of the length of cloth bag longer, have from the length of 2 meters to 10 meters all sizes, unconfined high velocity air bundle forms brute force near the cloth bag inner surface the cloth sack on the one hand and washes away, cause the cloth bag life-span to shorten, oversize because of cloth bag on the other hand, air-flow can not arrive the bottom, can not implement deashing completely.For solving this difficult problem; on the mouth of cloth bag, add a metal trunnion that inlet diameter is big, mid diameter is little, outlet diameter is big slightly; the device that is called the venturi injector; to slow down the impulsive force of import department; and the distance travelled of air-flow of effectively extending; both protect cloth bag, and can implement deashing completely to cloth bag again.Traditional injector is arranged on skeleton bag cage oral area, because of the structure that its throat diameter dwindles, when air-flow outwards flows out from cloth bag is inner, resistance can increase, not only can increase energy consumption, and when the device space, area and SR are subjected to limiting to, make design and use all to be subjected to obstacle.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of improved injector dedusting skeleton is provided, and it has solved the contradiction of resistance and deashing requirement, energy efficient.
For reaching above-mentioned purpose, the utility model is taked following technical scheme: the utility model includes: skeleton, injector is characterized in that: the bag cage mouth upper fixed at skeleton is connected with some perpendicular muscle, and injector has been fixedly connected on the perpendicular muscle.
The utility model is taked technique scheme, has following beneficial effect: the utility model is connected with some perpendicular muscle in the bag cage oral area upper fixed of skeleton, and the injector that has been fixedly connected on the perpendicular muscle makes injector surpass the position of the general assembly mouth of skeleton and cloth bag.Air-flow not only can outwards flow out from the larynx of injector is inner, also can outwards flow out from the brace rod space of injector outside.This structure has not only solved the contradiction of resistance and deashing requirement, and lowered secondary is entered cloth bag inside from cloth bag and skeleton general assembly mouth by induced draft resistance, increasing because of this space, the deashing throughput that enters in the cloth bag is also strengthened, can guarantee that ash-removal effect is more thorough on the one hand, on the other hand under the same ash-removal effect of design, but the save compressed air consumption, thus energy efficient.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated:
Fig. 1 is the utility model structure diagram.
Mark among the figure: 1-skeleton, 2-injector, 3-bag cage mouth, the perpendicular muscle of 4-, the vertical muscle of 5-
The specific embodiment
By shown in Figure 1, the utility model includes: skeleton 1, injector 2, be connected with some perpendicular muscle 4 in bag cage mouth 3 upper fixed of skeleton 1, and injector 2 has been fixedly connected on the perpendicular muscle 4.Perpendicular muscle 4 of the present utility model is an one with the vertical muscle 5 of skeleton 1, is the extension of vertical muscle 5.
Claims (2)
1. injector overhead system dedusting skeleton, include: skeleton (1), injector (2) is characterized in that: bag cage mouth (3) upper fixed at skeleton (1) is connected with some perpendicular muscle (4), and injector (2) has been fixedly connected on the perpendicular muscle (4).
2. a kind of injector overhead system dedusting skeleton according to claim 1, perpendicular muscle (4) is an one with the vertical muscle (5) of skeleton (1), is the extension of vertical muscle (5).
