Abstract

The utility model relates to a bidirectional hydrocyclone separation bag filter, which comprises a box body for the bag filter. The box body comprises a dust hopper, a middle box body and an upper box body which are connected in sequence, an air discharging hole is arranged on the upper box body, the middle box body is internally provided with a filter bag, the lower end of the dust hopper is provided with a dust unloading hole, an air intake duct which comprises an arc-shaped pipeline and a connecting pipeline is also connected on the box body, one end of the connecting pipeline is connected with the gas exhaust duct of a dust discharging device, the other end is connected with the arc-shaped pipeline, and the orifice at the other end of the arc-shaped pipeline is opposite to the dust hopper. The utility model enables the dust entering into the arc-shaped pipeline to be separated under the action of the centrifugal force through making the air intake duct of the bag filter into an arc-shaped elbow, thereby enabling the dust contained in the dusty air and the air to be separated, so that not only the contact between the dust and the filter bag is reduced, and the purifying efficiency and the continuous working time of the bag filter are improved, but also the purifying effect of the equipment can be improved.

Description

A kind of bidirectional rotational flow separation cloth bag dust remover

Technical field:

The utility model relates to a kind of sack cleaner, particularly a kind of bidirectional rotational flow separation cloth bag dust remover.

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 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 moisture content in the big or dusty gas of dust concentration, can further increase the deashing time and the difficulty of sack cleaner.

The utility model content:

The purpose of this utility model is: a kind of bidirectional rotational flow separation cloth bag dust remover is provided, the utility model 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.

The technical solution of the utility model: a kind of bidirectional rotational flow separation cloth bag dust remover, the casing 1 that comprises sack cleaner, the composition of casing 1 comprises the ash bucket 7 that connects successively, middle casing 8 and upper box 9, on upper box 9, be provided with gas discharge outlet 10, in middle casing 8, filter bag 6 is housed, be provided with cinder-discharging port 11 in ash bucket 7 lower ends, 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 the tubaeform mouth of pipe.

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

Compared with the prior art, the utility model 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 directly is injected into the ash bucket of stacking dust under action of centrifugal force, can reduce the contact rate of moisture dust and heavier dust and filter bag in the dusty gas so greatly, in the sack cleaner course of work, reduce the laying dust amount on the filter bag, improve purification efficiency, stream time and the clean-up effect of sack cleaner.Therefore the utility model has the excellent popularization value and use value.

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the vertical view of Fig. 1.

The specific embodiment:

Embodiment of the present utility model: as Fig. 1, Fig. 2 and shown in Figure 3, a kind of bidirectional rotational flow separation cloth bag dust remover, the casing 1 that comprises sack cleaner, casing 1 is by ash bucket 7, middle casing 8 and upper box 9 are connected in sequence, on upper box 9, be provided with purified gas outlet 10, in middle casing 8, be equipped with and be used for the filter bag 6 of Chalk-dust filtering, be provided with in ash bucket 7 (also being lower box) lower end and be used for going out clearly the cinder-discharging port 11 of dust in the casing, on casing 1, also be connected with admission line 2, admission line 2 comprises arc pipe 3, connecting pipe 4, arc pipe 3 is positioned at casing 1, and arc pipe 3 is two, two are the in-line connection after connecting by " fourth " font pipeline 5 with arc pipe 3, another interface of " fourth " font pipeline 5 is connected with connecting pipe 4, the other end of connecting pipe 4 is connected with the smoke discharging pipe of discharging dust-laden device, for guaranteeing that the dust that flies out from arc pipe 3 can directly fall into ash bucket 7, the mouth of pipe of arc pipe 3 other ends is relative with ash bucket 7, and the critical point of the arc pipe 3 relative with ash bucket 7 is made as tubaeform mouth of pipe shape; Be introduced in like this dusty gas in the admission line 2 arc pipe 3 in according to the suffered centrifugal force of quality difference of each material of dusty gas inside also difference to some extent, dust and gas are produced separate the back by the different tracks campaign, from dusty gas isolated dust under action of centrifugal force from tangentially directly flying into the ash bucket 7 of sack cleaner after the horn mouth of arc pipe 3 flies out, there is not dust separated from the gas, rise to the middle casing 8 of sack cleaner, dust is attracted on the filter bag 6, gas rises to upper box 9, discharges from gas discharge outlet 10.
