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

Built-in whirlwind tube sack cleaner
Technical field
The present invention relates to deduster equipment, be specifically related to a kind of built-in whirlwind cartridge type 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 exist than big-difference with the design fuel characteristic owing to go into stove fuel, make boiler fly ash content be higher than design load, because fly ash granule causes the sack cleaner serious wear more greatly, directly influenced 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 the built-in whirlwind tube sack cleaner of operating cost again.
The technical solution used in the present invention is: built-in whirlwind tube is set in the deduster shell of this deduster, and the shape of described built-in whirlwind tube is consistent with the deduster shell, and both central lines; The top of described deduster shell and built-in whirlwind tube and affixed with card respectively, the lower end of built-in whirlwind tube is fixed by flow guiding diaphragm and deduster shell, and the middle part of built-in whirlwind tube is fixed by support bar and deduster shell; On the sidewall of deduster shell, smoke inlet is set, the cleaning air cavity is set above card, and on the cleaning air cavity, exhanst gas outlet is set.
Surrounded annular cyclone chamber between described deduster shell and the built-in whirlwind tube.
Described flow guiding diaphragm plays the effect of water conservancy diversion to the flue gas of described annular cyclone chamber outlet, and 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 that opening makes progress all is housed on each circular hole.
After flue gas enters deduster from smoke inlet; at first flue gas is carried out rectification through annular cyclone chamber; under the effect of centrifugal force and gravity, oarse-grained flying dust is deposited to grey storehouse; 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 deduster separative efficiency, has reduced operating cost again; The present invention is strong to the adaptability of fuel, when going into stove fuel and designing fuel characteristic to exist than big-difference, also can guarantee the use of cloth bag safety economy, often change in the biomass fermentation 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 vertical view.
Number in the figure:
1-deduster shell; The 2-flow guiding diaphragm; The 3-support bar; 4-annular cyclone chamber; The built-in whirlwind tube 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 cartridge type sack cleaner, the present invention will be further described below by the drawings and specific embodiments.
As shown in Figure 1, deduster shell 1 is a cylindrical shell, with top cover 8 the housing upper end is sealed.Built-in whirlwind tube 5 is set in the deduster shell 1, and the shape of described built-in whirlwind tube 5 is consistent with deduster shell 1, and both central lines; The top of described deduster shell 1 and built-in whirlwind tube 5 and affixed with card 6 respectively, the lower end of built-in whirlwind tube 5 is fixing with deduster shell 1 by 4 flow guiding diaphragms of evenly arranging 2, and the middle part of built-in whirlwind tube 5 is fixing with deduster shell 1 by support bar 3.Form an annular cyclone chamber 4 between built-in whirlwind tube 5 and the deduster shell 1.Card 6 is circular, and the some circular holes by arranged in concentric circles are arranged on it, and the cloth bag that opening makes progress all is housed on each circular hole.Smoke inlet 10 is set on the sidewall of deduster shell 1, cleaning air cavity 9 is set above card 6, and on cleaning air cavity 9, exhanst gas outlet 7 is set.
When the processing assembling, built-in whirlwind tube 5 can be divided into a few part assemblings; For built-in whirlwind tube is installed and fixed firmly, flow guiding diaphragm can be fixed with built-in whirlwind tube and deduster shell respectively; Built-in whirlwind tube 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 4 pairs of flue gases of annular cyclone chamber; under the effect of centrifugal force and gravity, oarse-grained flying dust is deposited to grey storehouse; 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.
