Abstract
The utility model relates to a cloth bag dust remover used for continuously processing dust in dusty airflow. A circular cloth bag is suspended. The lower part of a box body in the dust remover is provided with a dust cleaning valve. The utility model adopts the method that chambered airflow is switched and dust is shaken off by the cloth bag automatically for cleaning accumulated dust in the cloth bag.
Description
This deduster is in environmental engineering and the Labor Protection, is used for eliminating the novel sack cleaner of dust-contained airflow dust.
The sack cleaner kind is a lot of both at home and abroad, as pulse bag type dust collector, and the double-deck sack cleaner of LFS type blowback wind, the rotary counter-blowing flat bag filter, and more novel downflow type flat bag filter (China Patent No. 85200663.2) etc.Though these dedusters have been produced for many years, all there are some problems in using, mainly be that the deashing device energy consumption is big, deashing mechanism is complexity but also fragile not only.More advanced downflow type flat bag filter adopts the deashing method of leaking out, and confirms that deashing is unclean, does not reach to give the phase effect in actual the use.Its cloth bag adopts flat cloth bag, and dust stops up cloth bag easily in the use.
Purpose of design of the present utility model is a shortcoming of attempting to overcome above-mentioned sack cleaner, adopts newly-designed deashing device and garden cloth bag mode, thereby a kind of novel sack cleaner is provided.
Structure of the present utility model is provided by following examples and accompanying drawing thereof.
Accompanying drawing is the schematic diagram according to the sack cleaner that the utility model proposes.
Describe structure of the present utility model and working condition in detail below in conjunction with accompanying drawing.
During this deduster work, dust-contained airflow is entered in the upper box ［ 2 ］ by blast pipe ［ 1 ］, distribute then and enter in cloth bag ［ 3 ］, ［ 4 ］, through the cloth bag filtration, soot cleaning valve ［ 6 ］, ［ 7 ］ and the communicating pipe ［ 8 ］ of the unlatching of casing ［ 5 ］ bottom are discharged by discharge pipe ［ 9 ］ in the clean gas process.Dust in the dust-contained airflow is attached on cloth bag ［ 3 ］, ［ 4 ］ inwall, when dust thickness is increased to a certain degree, may fall voluntarily in lower box (ash bucket) ［ 10 ］, is discharged by ash exhauster ［ 11 ］.Dust also might be adsorbed on the inwall of cloth bag ［ 3 ］, ［ 4 ］ and not fall, and this just needs regularly deashing, and dust is shaken off.
The mode that this deduster deashing adopts locellus airflow-reversing, cloth bag to shake off dust voluntarily.Please see accompanying drawing.Casing in the deduster ［ 5 ］ is divided into two Room by dividing plate ［ 12 ］, a Room ［ 13 ］ and two Room ［ 14 ］ (can be divided into multicell).Deduster is worked under negative pressure state.When dust is adsorbed on the cloth bag inwall when many, regularly adjustable controller ［ 15 ］ sends instruction, electromagnet ［ 16 ］ on the soot cleaning valve ［ 6 ］ is got, soot cleaning valve ［ 6 ］ is closed by opening to become, and at this moment the cloth bag ［ 3 ］ in the Room ［ 13 ］ of middle casing ［ 5 ］ is outside becomes atmospheric pressure state by negative pressure state.But the inner two ends of cloth bag ［ 3 ］ communicate with cloth bag ［ 4 ］ in two Room ［ 14 ］ by upper box ［ 2 ］ and lower box ［ 10 ］, and still be in the negative pressure duty two Room ［ 14 ］ this moment, so the interior pressure of the cloth bag ［ 3 ］ of a Room ［ 13 ］ still is negative pressure.Because of cloth bag ［ 3 ］ inside and outside differential pressure, cause cloth bag ［ 3 ］ to shrink and become flat like this.After several seconds, timing controller ［ 15 ］ sends instructions again, electromagnet ［ 16 ］ dead electricity, and soot cleaning valve ［ 6 ］ is opened by closing to become, and a Room ［ 13 ］ recover the negative pressure duty by malleation, and cloth bag ［ 3 ］ is by shrinking the normal operative condition that becomes bulging capsule again.Dust stratification in one of these receipts, cloth bag ［ 3 ］ is shaken off, and has finished the grey process of asking of the interior cloth bag in a Room ［ 13 ］ ［ 3 ］.Timing controller ［ 15 ］ sends instructions then, makes the electromagnet ［ 17 ］ of soot cleaning valve ［ 7 ］ get electric dead electricity, makes the cloth bag ［ 4 ］ in two Room ［ 14 ］ also finish above-mentioned deashing process.Large-scale deduster can adopt the above multicell in two Room, and its deashing can repeat said process in proper order.
In order to overcome the shortcoming that flat cloth bag stops up easily, the cloth bag of this deduster ［ 3 ］, ［ 4 ］ adopt garden shape to be suspended.
The utility model deduster has the following advantages:
1, deashing device is made up of timing controller and soot cleaning valve, and structure is very simple. Its power is non-damageable electromagnet, reliable operation, a little repair.
2, the electromagnet of deashing device is a discontinuous operation, only switches on for tens seconds during deashing, energy-conservation apparent notes.In addition, the back blowing machine that does not need compressed air and deashing to use.
3, cloth bag adopts circular cloth bag, can not stop up.
