Abstract

The invention discloses a deduster utilizing combination of a plurality of ash removal methods. The deduster belongs to environmental protection equipment and especially relates to a dedusting device. More than half of work energy consumption of the deduster dependents on ash removal effects of a dedusting bag. According to different dedusting conditions and difference of adherence intensity to the dedusting bag, different ash removal methods are adopted. Aiming at easily-removed dust, a return air back-flushing process is utilized and one or more large vibrators produce large vibration action on the whole dedusting box, aiming at dust having middle removal difficulty, a return air back-flushing process is utilized and multiple small vibrators of which the number is equal to the number of the deduster cleaning chambers are used for directly vibrating a reinforcing steel bar inner frame in the cloth dedusting bag thereby directly vibrating the dedusting bag, and aiming at difficultly-removed dust having oiliness and adhesion, all air sprayed by a whole fan is used for intensively blowing one of the deduster cleaning chambers and multiple small vibrators of which the number is equal to the number of the deduster cleaning chambers are used for directly vibrating a reinforcing steel bar inner frame in the cloth dedusting bag thereby directly vibrating the dedusting bag. Through combination of a plurality of the ash removal methods, the deduster has dedusting effects superior to the simple superposition of dedusting effects of single ash removal methods, can always control dust thickness in 1mm and can manyfold reduce blower fan power energy consumption.

Description

The deduster of multiple purge mode use
Technical field
Multiple purge mode is also used deduster, belongs to environmental protection equipment, is specifically related to dust arrester.
Background technology.
The work power consumption of deduster, a greater part of quality that depends on the grey effect that falls on dust settling pocket, because dust is tied thicker and thicker when overanxious, after through air, the gap that will first cross dust could arrive in cloth bag discharges, what dust was thick like this must increase power of fan more, and the therefore method of deashing becomes the key technology of deduster.Purge mode is all single method at present, as shakes formula, rotary counter-blowing formula, high-pressure gas box pulsed etc., and the dust on cloth bag also often has 3-8 millimeters thick, and air, through the resistance of dust, can be still several times of dust settling pocket layer, and its reform still has a lot of potentiality to dig.
Summary of the invention
For the difference of dedusting operating mode, dust settling pocket adhesion strength difference is taked to different modes: the selecting of easy-to-clean ash, return air blowback+one or two big bang device is to dust cleaning case entirety big bang; Selecting of medium deashing, return air blowback+deduster clean room divides several chambers just with many smaller tremors devices, and what locellus was grown also can two to three of Room smaller tremors device, and reinforcing bar inner frame in cloth bag is directly shaken to dust settling pocket; The difficult deashing of oiliness adhesion, adopt the air quantity of overall blower fan to concentrate blowback wherein one Room+deduster clean room to divide several chambers just with many smaller tremors devices, steel skeleton in cloth bag is directly shaken, pulse backblowing even again adds high pressure.Multiple ash removal method also, with reaching the effect that 1+1 is greater than 3, can be controlled at dust thickness in one millimeter all the time, will reduce at double blower fan power consumption.
The deduster of multiple purge mode use, by deduster, blower fan, electromagnetic shaker or be made up of large air exhaust passage etc., its architectural feature is: when blower fan back-blowing or pressure-air blowback, deashing when disposing big bang or smaller tremors device and coordinating back-blowing.
The deduster of multiple purge mode use, by deduster, blower fan, electromagnetic shaker or be made up of large air exhaust passage etc., its architectural feature is: on dust cleaning case, configure big bang device, the deashing while coordinating back-blowing to shake the mode of whole casing.
The deduster of multiple purge mode use, by deduster, blower fan, electromagnetic shaker or formed by large air exhaust passage etc., its architectural feature is: in the clean room of separating at deduster, through transverse and longitudinal hitch by smaller tremors device, be connected as a single entity with the reinforcing bar inner frame in several dust settling pockets, while coordinating back-blowing, directly shake dust settling pocket deashing.
The deduster of multiple purge mode use; by deduster, blower fan, electromagnetic shaker or formed by large air exhaust passage etc.; its architectural feature is: at fan outlet or together with blower fan root; by the exhaust of multiple blower fans; import a large air exhaust passage; in air exhaust passage outlet, pneumatic control door is set; only need passage moment to close the door; the air that just several blower fans can be discharged; give the dirt pocket reverse gas cleaning of single shutdown; as many especially in dedusting locellus, can suitably increase the special air inlet of locellus and pneumatic door gear, guarantee the effect of the concentrated reverse gas cleaning of Wind Volume.

Detailed description of the invention
The deduster of multiple purge mode use, by deduster, blower fan, electromagnetic shaker or be made up of large air exhaust passage etc., we are to many former pulse dust collectors, and the summary of experience that transform the positive back flushing type deduster of energy-conservation locellus as is:
Do impeller blasting, pitch is heated, and the amount of dust such as mixing plant are more and dust is heavier, belong to the dedusting of easy-to-clean ash class, can select axial flow blower 10 blowbacks, strengthen electromagnetic shaker 9 and shake two kinds of modes deashings simultaneously of whole deduster 7.
Do that various dusts collect, belong to deashing difficulty medium, can select axial flow blower 10 blowbacks, add smaller tremors device 5, combine group frame 4 through transverse and longitudinal, 3, the two kinds of modes of dust settling pocket and reinforcing bar inner frame of directly shaking coordinate deashing.
Do the collection of converter flue dust, the light difficult deashing of its weight of dust, axial flow blower 10 can be selected, strengthen air exhaust passage 8, join smaller tremors device 5, combine group frame 4 through transverse and longitudinal, shake dust settling pocket and reinforcing bar inner frame 3, tremble two kinds of means of ash and use deashing with adding air quantity blowback and raising.
With the collection of oil fume, the serious special difficult deashing of the sticky bag of its dust, can select axial flow blower 10 to strengthen air exhaust passage 8, join smaller tremors device 5, combine group frame 4 through transverse and longitudinal, shake dust settling pocket and reinforcing bar inner frame 3, then add high pressure air pulse moment blowback, add Wind Volume blowback, improve and tremble ash, moment and put three kinds of means of high pressure big gun and also use mode deashing with special air inlet.
By the also use practice of above-mentioned purge mode, can protect the outer dust thickness of cloth bag and be controlled at all the time in 1 millimeter, can reduce in practice power of fan 60-80%.
Those of ordinary skill in the art will be appreciated that, above embodiment is only for this technology is described, each technology can be implemented separately, also enforcement capable of being combined, so not as the restriction to this technology, as long as in the essential scope of this technology, variation, modification to the above embodiment all will drop in the scope of this technological right claim.
