Abstract
The utility model relates to dust collector equipment, in particular to a bag-type dust collector with a built-in cyclone tube. The built-in cyclone tube is arranged between the outermost ring of bag of the dust collector and a shell of the dust collector, the center of the built-in cyclone tube is in the same central line with the shell of the dust collector, the upper end is linked with a pattern board, and the lower end is connected with the shell of the dust collector by a division membrane that is arranged between the built-in cyclone tube and the shell of the dust collector; and the built-in cyclone tube and the shell of the dust collector form an annular smoke channel named as an annular cyclone chamber. After entering the dust collector, the smoke firstly passes through the annular cyclone chamber, large-grain flying ashes are settled in an ash bin under the action of centrifugal force and the gravity, and other smoke uniformly enters the internal chamber of the dust collector after being rectified by the division membrane for dust collection by cloth bags, thereby not only avoiding abrasion of large-grain flying ashes to the cloth bags, but also avoiding concentrative flushing of the cloth bags by smoke, and further playing a role in protecting the cloth bags and improving the processing capability of the dust collector.
Description
Technical field
The utility model relates to deduster equipment, is 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 purpose of this utility model is to overcome the deficiencies in the prior art, the advantage that provides a kind of technical ability to keep prior art, and the while has been reduced the built-in whirlwind tube sack cleaner of operating cost again.
The technical solution adopted in the utility model 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.
The beneficial effects of the utility model are:
This deduster has kept the high advantage of conventional cloth bag deduster separative efficiency, has reduced operating cost again; The utility model 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 utility model 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 utility model provides a kind of built-in whirlwind cartridge type sack cleaner, below by the drawings and specific embodiments the utility model is described further.
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.
