Abstract

The invention relates to a dust removal method of a bidirectional cyclone separation bag-type dust remover; an intake pipe of the bag-type dust remover is produced into an arch-shaped pipeline, the pipe orifice of the intake pipe which is connected with the bag-type dust remover faces a dust hopper of the bag-type dust remover, therefore, the dust in the dust-containing gas which is led into the intake pipe of the bag-type dust remover can generate high centrifugal force in the arch-shaped pipeline and is separated from the gas in virtue of the centrifugal force; the dust separated from the gas is directly jetted into the dust hopper of the bag-type dust remover along the opening direction of the arch-shaped pipeline so as to reduce the load of a filter bag of the bag-type dust remover. In the invention, the intake pipe of the bag-type dust remover is produced into the arch-shaped pipeline, so that the dust which enters the external intake pipe can be separated from the gas under the action of centrifugal force, in this way, the contact between the dust and the filter bag can be reduced and the purification efficiency and continuous operating time of the bag-type dust remover as well as the purification effect of the device can be improved.

Description

A kind of bidirectional rotational flow separation cloth bag dust remover and dust collection method thereof

Technical field:

The present invention relates to a kind of sack cleaner and dust collection method thereof, particularly a kind of bidirectional rotational flow separation cloth bag dust remover and dust collection method thereof.

Technical background:

Filtration to dusty gas all is to adopt sack cleaner to filter at present, its operation principle is dusty gas is incorporated into sack cleaner by connecting pipe a casing, dusty gas is subjected to the absorption affinity of air-introduced machine close to filter bag, dust is attracted on the filter bag, and cleaned gas is discharged in filter bag, thereby reaches the effect of air cleaning.Because of the dust that is adsorbed on the filter bag can will increase the circulating resistance that air passes strainer gradually in banking process, reduce the filter effect of filter bag, therefore blowback system generally all is set on sack cleaner, be used for removing the dust stratification on the filter bag, the dust of removing falls into the ash bucket of sack cleaner, and the cinder-discharging port from ash bucket is discharged.Because of blowback system sack cleaner when working need quit work, need the strainer dust adsorbed many more, the also corresponding raising of blowback system operating frequency, to reduce the operating efficiency of sack cleaner greatly like this, when particularly containing water in the big or dusty gas of dust concentration, can increase the deashing time and the difficulty of sack cleaner more.

Summary of the invention:

The objective of the invention is to: a kind of bidirectional rotational flow separation cloth bag dust remover and dust collection method thereof are provided, the present invention separates with gas in advance by utilizing the admission line dust that quality in the dusty gas is heavier, low the contacting of moisture dust and heavier dust and filter bag in the dusty gas, improve the purification efficiency and the stream time of sack cleaner, can overcome the deficiencies in the prior art.

Technical scheme of the present invention: a kind of dust collection method of bidirectional rotational flow separation cloth bag dust remover, this method is that the air inlet pipe with sack cleaner is made as arc pipe, the air inlet pipe mouth of pipe that is connected on the sack cleaner is relative with the ash bucket of sack cleaner, make the dust that is incorporated in the interior dusty gas of sack cleaner air inlet pipe in arc pipe, produce bigger centrifugal force, and it is separated from the gas under this action of centrifugal force, dust separated from the gas directly is injected into the ash bucket of sack cleaner along the opening direction of arc pipe, thereby reduces the load of sack cleaner filter bag.

A kind of bidirectional rotational flow separation cloth bag dust remover, the casing (1) that comprises sack cleaner, the composition of casing (1) comprises ash bucket (7), middle casing (8) and upper box (9), on upper box (9), be provided with gas discharge outlet (10), filter bag (6) is housed in middle casing (8), be provided with cinder-discharging port (11) in ash bucket (7) lower end, it is characterized in that: on casing (1), also be connected with admission line (2), admission line (2) comprises arc pipe (3), connecting pipe (4), connecting pipe (4) one ends are connected with the smoke discharging pipe of dust exhaust, the other end is connected with arc pipe (3), and the other end mouth of pipe of arc pipe (5) is relative with ash bucket (4).

Arc pipe (3) is positioned at the casing (1) of sack cleaner.

The mouth of pipe of the arc pipe (3) relative with ash bucket (4) is a horn mouth.

The quantity of arc pipe (3) is two, and two arc pipes (3) connect by be in-line by " fourth " font pipeline (5), and connecting pipe (4) is connected another port of " fourth " font pipeline (5).

Compared with the prior art, the present invention is made as curve bend by the admission line with sack cleaner, the dusty gas dust under action of centrifugal force that enters in the arc air inlet pipe is separated with gas, dust after the separation is subjected to centrifugal action directly to be injected into the ash bucket of stacking dust, can greatly reduce the contact rate of moisture dust and heavier dust and filter bag in the dusty gas like this, in the bag-type dust course of work, reduce the laying dust amount on the cloth bag, improved the clean-up effect of purification efficiency, stream time and the equipment of sack cleaner.Therefore the present invention has the excellent popularization value and use value.
