The specific embodiment
The present invention is described in further detail below in conjunction with embodiment and accompanying drawing, but embodiments of the present invention are not limited thereto.
Consult shown in Figure 1, the invention provides a kind of bottom flue dust-filtering scavenge unit, comprise cyclone dust collectors and the ash can 2 that is connected with cyclone dust collectors, it also comprises the filter screen deduster that is installed in the cyclone dust collectors, and is installed on the cyclone dust collectors outside to drive the vibrator of filter screen deduster vibration.
Preferable, cyclone dust collectors comprise filter housing 1, are located at gas approach 3, exhanst gas outlet 4 on the filter housing 1, and the bellows 5 that is positioned at filter housing 1 and is connected with exhanst gas outlet 4.Wherein, gas approach 3 is positioned at the side of filter housing 1, and exhanst gas outlet 4 is positioned at the top of filter housing 1, and ash can 2 is positioned at the lower end of filter housing 1, is convenient to dust like this and falls in the ash can 2 in the effect of self gravitation.And the filter screen deduster comprises the filter screen stand 6 that is installed on bellows 5 lower ends, and is installed on the screen pack 7 on the filter screen stand 6.Vibrator comprises that symmetry is installed on the electromagnetic vibrator 8 in the cyclone dust collectors outside, and the vibrating controller 9 of control electromagnetic vibrator 8 vibration frequencies and vibration intensity.Bellows 5 in the present embodiment has bigger flexibility and elasticity, so under the effect of bellows 5, filter screen stand 6 is subjected to the electromagnetic force of electromagnetic vibrator 8, can move along the direction of electromagnetic force along with bellows 5, and then the inwall of touching filter housing 1.Be that screen pack 7 produces vibration, be adsorbed on dust on the screen pack 7 and shaken and fall, fall into ash can 2.Preferably, filter mounting 6 is made for the magnetic material, and filter housing 1 is made for nonmagnetic material, and namely filter screen stand 6 can not be subjected to the effect of filter housing 1 and have influence on the control effect of electromagnetic vibrator 8.Further preferred, the material of filter mounting 6 is iron and steel, and the material of filter housing 1 is stainless steel, and then vibrating controller 9 control electromagnetic vibrators generation electromagnetic forces, and electromagnetic force penetrates 1 pair of filter mounting of filter housing, 6 generation active forces.General, the lower end that filter housing 1 is set is down trapezoidal structure, it forms one and collects mouth, falls into ash can 2 with the convenient dust that drops from screen pack 7.
Again in conjunction with Fig. 1, shown in Figure 2, a kind of bottom flue dust-filtering method of the present invention, its filtration step comprises:
The first step, the gas approach 3 of cyclone dust collectors is connected with bottom flue, and starts cyclone dust collectors work;
Dust in second step, the bottom flue enters in filter housing 1 inner chamber of cyclone dust collectors, and the screen pack 7 on the filter screen deduster filters and the absorption dust;
The 3rd step, Vibration on Start-up controller 9 control electromagnetic vibrators 8 produce electromagnetic force, the filter screen stand 6 of filter screen deduster direction along electromagnetic force under the electromagnetic force driving effect of electromagnetic vibrator 8 produces vibration, and then the inwall of touching filter housing 1, be that screen pack 7 produces vibration, being adsorbed on dust on the screen pack 7 is shaken and is fallen, fall into ash can 2, realize the removing of dust on the screen pack 7.Certainly in use, can adjust vibration frequency and the vibration intensity of electromagnetic vibrator 8 by vibrating controller 9, to reach best dust cleaning effect.
Bottom flue dust-filtering scavenge unit of the present invention is in industrial processes or laboratory test process, and the dust-filtering and the dust that are used in the bottom flue are removed.On the one hand cyclone dust collectors and filter screen deduster are combined, improved the flue gas ash removal effect of bottom flue, the vibrator that is provided with the non-insertion mounting means on the other hand in the cyclone dust collectors outside can guarantee the long-term use of screen pack, make the use that bottom flue can be steady in a long-term, make smoke filtration have long-term, efficient, stable advantage simultaneously.
Above-described embodiment is preferred implementation of the present invention; but embodiments of the present invention are not restricted to the described embodiments; other any do not deviate from change, the modification done under spiritual essence of the present invention and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
