Abstract

Disclosed is a cyclone bag-type combined dust cleaner which comprises an upper box, a middle box and a lower box integrated into one box. Plural cyclone barrels are fixed in the upper box. An air inlet is connected with the cyclone barrels by an air inlet valve. The bottom of each cyclone barrel is provided with an air-locking valve. The lower outlet of each cyclone barrel is provided with an overflow pipe spiral and the upper outlet is connected with a corresponding child room in the middle box. The middle box is provided inside with plural bag cages communicated with the upper box and each bag cage is covered with a filter bag. The upper box is connected with an air outlet. An air bag is connected with the upper opening of each bag cage in the upper box by a blow pipe with a pulse valve. The filter bags have a long service life, the dust cleaner is simple in structure, good in dedusting effects and low-consumption and does not have double absorption of dust. The utility model can be widely used in places and industries of high dust concentration and is a perfect environment-protection dedusting device.

Description

The bag-type whirlwind combined dust remover

Technical field:

The utility model relates to a kind of environmental protection cleaner, especially bag-type whirlwind combined dust remover.

Background technology:

Existing cleaner mainly contains cyclone dust collector, mist dust remover, high-voltage electrostatic dust separator, impulse bag dust-precipitator, and the pluses and minuses of oneself are respectively arranged, and cyclone dust collector is simple in structure, and efficient is low, is unfavorable for the collection of fine dust; Pulse bag type dust collector, the efficiency of dust collection height, but filter bag is easy to wear, and life-span of the filter bag is short.Mist dust remover needs consume water resources, and high-voltage electrostatic dust separator need consume a large amount of electric energy, and damages easily.Lack that a kind of good dedusting effect, long service life, power consumption are low, the deduster of dependable performance.

Summary of the invention:

The purpose of this utility model provides a kind of bag-type whirlwind combined dust remover, can have simultaneously that good dedusting effect, long service life, power consumption are low, the characteristics of dependable performance.

The purpose of this utility model realizes as follows: this deduster relates to whirlwind tube and bag cage and cover filter bag thereon, by last, in, lower box is combined in one and constitutes casing, a plurality of whirlwind tubes are fixed in the lower box, air inlet links to each other with the whirlwind tube by the air intake valve, each whirlwind tube lower end is to there being air valve, whirlwind tube outlet down has the overflow pipe spiral, the locellus that the upper outlet of each whirlwind tube is corresponding with middle casing is connected, be furnished with some bag cages that lead to upper box in the middle casing, the bag cage is covered with filter bag, upper box links to each other with air outlet, has gas bag to be connected to the place suitable for reading of upper box inner bag cage by the winding-up pipe that has pulse valve.Dusty gas enters the whirlwind tube by air inlet, the dust that particle is big is because the friction and the action of centrifugal force of high velocity air and cyclone wall drop to lower cone downwards, fine dusts enters the branch mailbox air chamber by whirlwind tube intermediate exhaust pipe, through filter bag dust-filtering and gas is discharged, dust enters lower cone, can control deashing automatically by automatically controlled PC, close air chamber, unload grey supervisor, each air chamber is by configuring stop air chamber, deashing, carry out again and again, because filter bag has only participated in the filtration work of fine dusts, the degree of wear is lower, and increase service life; Because adopt the method for two-stage dust removal, efficient is higher.

The bag cage evenly distributes in middle casing.

The utility model is simple in structure, good dedusting effect, and life of bag filter is long, and it is low to consume energy, and dust does not produce second adsorption, is widely used in big place of dust concentration and industry, as building material industry, is a kind of desirable environmental protection cleaner.

Description of drawings:

Accompanying drawing is the structural representation of the utility model bag-type whirlwind combined dust remover.

1, overflow pipe spiral; 2, air valve; 3, inspect door; 4, whirlwind tube; 5, blanking cone; 6, bag cage; 7, filter bag; 8, inspection platform; 9, railing; 10, air outlet; 11, top cover; 12, support; 13, lower box; 14, air inlet; 15, air intake valve; 16, cylinder; 17, middle casing; 18, pulse valve; 19, gas bag; 20, winding-up pipe; 21, upper box.

The specific embodiment:

With reference to accompanying drawing, it is by upper box 21, middle casing 17 and lower box 13 are combined in one and constitute casing, between connect by flange, upper box 21 tops are provided with top cover 11, be used for maintenance and change filter bag, lower box is fixing by support 12, the lower box both sides have inspects door 3, a plurality of whirlwind tubes 4 are fixed in the lower box 13, air inlet 14 links to each other with whirlwind tube 4 with control cylinder 16 by air intake valve 15, each whirlwind tube 4 lower end is to there being air valve 2,4 times outlets of whirlwind tube have overflow pipe spiral 1, and overflow pipe spiral 1 is connected with lower box 13 usefulness flanges, and the upper outlet of each whirlwind tube 4 is connected by blanking cone 5 and middle casing 17 corresponding locellus, be furnished with some bag cages 6 that lead to upper box 21 in the middle casing 17, bag cage 6 is covered with filter bag 7, and upper box 21 links to each other with air outlet 10, has gas bag 19 to be connected to the place suitable for reading of upper box 21 inner bag cages 6 by the winding-up pipe 20 that has pulse valve 18, during being fixed in, inspection platform 8 and railing 9 on the casing 17, be convenient to the maintenance of equipment.Dusty gas enters whirlwind tube 4 by air inlet 14, owing to be subjected to high velocity air and centrifugal action, big powder ash particle falls into air valve 2 tops, casing 17 air chambers during fine dusts is entered by whirlwind tube upper outlet, dust enters upper box 21 after filter bag 7 filters, discharge after entering air-introduced machine by air outlet 10, thereby reach dust removing effects, by pulse valve 18 control gas bags 19, supply gas by winding-up pipe 20, regularly clear up the dust of filter bag absorption, the dust of being cleared up enters whirlwind tube 4 through blanking cone 5 and falls into air valve 2 places, and air valve 2 began to unload ash automatically when air valve top dust arrived constant weight, entering overflow pipe spiral 1 discharges, this equipment is joined conventional external air pressure 0.5-0.7MPa, connects gas bag 19 and pulse valve 18 and winding-up pipe 20, finishes filter bag ash removal work.
