Abstract
The invention relates to dust collector equipment, in particular to a built-in cyclone bag-type dust collector. A built-in cyclone is installed between the outermost ring of the dust collector and the shell of the dust collector; the centers of the built-in cyclone and the shell of the dust collector are on the same center line; the upper end is connected with a pattern card, and the lower end is connected with the shell of the dust collector by a diversion diaphragm which is installed between the built-in cyclone and the shell of the dust collector; and the built-in cyclone and the shell of the dust collector form an annular gas fume channel called an annular cyclone chamber. Gas fume firstly passes through the annular cyclone chamber after entering the dust collector; under the action of centrifugal force and gravity, the fly ash of large particles settles to an ash bin, and the rest gas fume evenly enters the inner chamber of the dust collector after rectified by the diversion diaphragm to dedust by the bag; thus, bag abrasion caused by fly ash of large particle can be avoided, and a plurality of bags intensively brushed by gas fume can be avoided to protect the bag and improve the handling capability of the dust collector.
Description
Technical field
The present invention relates to deduster equipment, be specifically related to a kind of built-in whirlwind sack cleaner.
Background technology
In the prior art, sack cleaner is a kind of deduster commonly used, and separative efficiency is very high, be widely used at electric power and chemical field, but there is larger difference owing to entering stove fuel with the design fuel characteristic, so that boiler fly ash content is higher than design load, because fly ash granule causes more greatly the sack cleaner serious wear, directly affected the economic benefit in power plant and chemical plant simultaneously.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the advantage that provides a kind of technical ability to keep prior art, the while has been reduced again the built-in cyclone bag-type dust collector of operating cost.
The technical solution used in the present invention is: built-in cyclone cylinder is set in the outer case of dust remover of this deduster, and the shape of described built-in cyclone cylinder is consistent with outer case of dust remover, and both central lines; The top of described outer case of dust remover and built-in cyclone cylinder and affixed with card respectively, the lower end of built-in cyclone cylinder is fixed by flow guiding diaphragm and outer case of dust remover, and the middle part of built-in cyclone cylinder is fixed by support bar and outer case of dust remover; Sidewall at outer case of dust remover arranges smoke inlet, and the cleaning air cavity is set above card, and at the cleaning air cavity exhanst gas outlet is set.
Surrounded the annular cyclone chamber between described outer case of dust remover and the built-in cyclone cylinder.
Described flow guiding diaphragm plays the effect of water conservancy diversion to the flue gas of described annular cyclone chamber outlet, its quantity is at least 4.
Described support bar be shaped as cylinder or cuboid.
Described card is circular, and the some circular holes by arranged in concentric circles are arranged on it, and the cloth bag of opening upwards all is housed on each circular hole.
After flue gas enters deduster from smoke inlet; at first through the annular cyclone chamber flue gas is carried out rectification; under centrifugal force and action of gravitation, oarse-grained flying dust is deposited to ash silo; evenly enter the deduster inner room after remaining flue gas process flow guiding diaphragm rectification and pass through bag-type dust; so not only avoided the bulky grain flying dust to the wearing and tearing of cloth bag but also avoided the fume centralized to wash away several cloth bags, cloth bag had been played the disposal ability that protective effect has also improved deduster simultaneously.Last flue gas enters the cleaning air cavity and discharges from exhanst gas outlet.
Beneficial effect of the present invention is:
This deduster has kept the high advantage of conventional cloth bag Separation Efficiency of Dust Remover, has reduced again operating cost; The present invention is to the strong adaptability of fuel, when entering stove fuel and designing fuel characteristic to have larger difference, also can guarantee the use of cloth bag safety economy, often change in the biomass power plant especially for use in fuel, its effect is more obvious, and its suitable equipment enlarging simple in structure, with low cost and industrialization.
Description of drawings
Fig. 1 (a) and Fig. 1 (b) are respectively front view of the present invention and top view.
Number in the figure:
The 1-outer case of dust remover; The 2-flow guiding diaphragm; The 3-support bar; 4-annular cyclone chamber; The built-in cyclone cylinder of 5-; The 6-card; The 7-exhanst gas outlet; The 8-top cover; 9-cleans air cavity; The 10-smoke inlet.
The specific embodiment
The invention provides a kind of built-in whirlwind sack cleaner, the present invention will be further described below by the drawings and specific embodiments.
As shown in Figure 1, outer case of dust remover 1 is cylindrical shell, with top cover 8 the housing upper end is sealed.Outer case of dust remover 1 is interior to arrange built-in cyclone cylinder 5, and the shape of described built-in cyclone cylinder 5 is consistent with outer case of dust remover 1, and both central lines; The top of described outer case of dust remover 1 and built-in cyclone cylinder 5 and affixed with card 6 respectively, the lower end of built-in cyclone cylinder 5 is fixing with outer case of dust remover 1 by 4 flow guiding diaphragms that are evenly arranged 2, and the middle part of built-in cyclone cylinder 5 is fixing with outer case of dust remover 1 by support bar 3.Form an annular cyclone chamber 4 between built-in cyclone cylinder 5 and the outer case of dust remover 1.Card 6 is circular, and the some circular holes by arranged in concentric circles are arranged on it, and the cloth bag of opening upwards all is housed on each circular hole.Sidewall at outer case of dust remover 1 arranges smoke inlet 10, and cleaning air cavity 9 is set above card 6, and at cleaning air cavity 9 exhanst gas outlet 7 is set.
When the processing assembling, built-in cyclone cylinder 5 can be divided into a few part assemblings; In order to make built-in cyclone cylinder that fixation is installed, flow guiding diaphragm can be fixed with built-in cyclone cylinder and outer case of dust remover respectively; Built-in cyclone cylinder top can weld or be fixed by bolts on the card.
After flue gas enters deduster from smoke inlet 10; at first carry out rectification through the 4 pairs of flue gases in annular cyclone chamber; under centrifugal force and action of gravitation, oarse-grained flying dust is deposited to ash silo; evenly enter the deduster inner room after remaining flue gas process flow guiding diaphragm 2 rectification and pass through bag-type dust; so not only avoided the bulky grain flying dust to the wearing and tearing of cloth bag but also avoided the fume centralized to wash away several cloth bags, cloth bag had been played the disposal ability that protective effect has also improved deduster simultaneously.Last flue gas enters cleaning air cavity 9 and discharges from exhanst gas outlet 7.
