Description

A kind of dust arrester
Technical field
The utility model is related to a kind of dust arrester, and in particular to a kind of sack cleaner and its bag cage. 
Background technology
Production and processing type enterprise all has vent gas treatment, particularly it is particularly acute in the dust pollution of cement production enterprise, there is substantial amounts of short grained dust in discharging and fly upward everywhere in the tunnel of manufacture of cement and the belt conveyor at storehouse bottom, because there are unequal emptying point and reloading point in all kinds of tunnels and storehouse bottom, be up to twenties, these emptying points are horizontal pipe arrangement because of space limitation, the horizontal pipe of long range easily causes line clogging, cloth wind is uneven again for each airborne dust point, so the dust removing effects of general deduster are undesirable, it is difficult to reach discharge standard.Further, since dust is stained seriously, when belt conveyor is run, operator cannot be introduced into tunnel and storehouse bottom and be maked an inspection tour and be overhauled, and nearly 200 meters of Belt Conveying line length, easily produce failure, have impact on the economic benefit development of enterprise;And be negatively affected to worker is healthy. 
So enterprise is in order to reach the index of environmental protection, discharged again after carrying out absorption processing to the tail gas produced in production using various dust arresters, such as gas wash tower, dust settling pocket, Water spray method, the tail gas after processing substantially meet the requirement of discharge.Wherein, sack cleaner due to putting into that small, arrangement is convenient, good dedusting effect and used by vast enterprise. 
Sack cleaner is made up of bag cage overcoat filter bag, and wherein bag cage is the support rib of filter bag, filter bag is kept certain shape in filter dirt and deashing process;Bag cage is to constitute tubular cage bone by perpendicular muscle and circle muscle, and filter bag is strutted, prevents that filter bag from collapsing.When dusty gas passes through deduster, dust is attached to the outer surface of filter bag, is then shaken off dust by blowback, reaches deashing purpose.Because filter bag is with diameter greater than bag cage diameter, filter bag is adjacent to a bag cage during filtering, and filter bag leaves a bag cage during blowback, the action for making filter bag and bag cage frequently contact, unclamp, easily make the position friction damage that filter bag is contacted with the perpendicular muscle of bag cage, life of bag filter is have impact on, and increases production cost, influence safety in production.In addition, the thickness of bag cage is usually to immobilize, when filter bag such as expands because of the efficiency of deduster, then traditional bag cage adaptability is not strong, is easily trampled on because of the excessive of filter bag, and causes cost to improve. 
Utility model content
The utility model seeks to solve above-mentioned deficiency there is provided a kind of dust arrester, reaches good dedusting effect, takes up an area purpose that is small, economizing on resources. 
In order to reach the effect above, the utility model provides a kind of dust arrester, including support, the branch is set up in directly over dedusting point, the fixed casing of pedestal upper end, it is provided with the middle of the upper box and lower box of the casing inside deflector, the upper box and is provided with sack cleaner, the bottom of lower box, which is connected with, unloads grey slide carriage;Blowing device is installed with the outside of the casing, the blowing device is connected by injection tube with upper box. 
The blowing device includes gas bag, and the two ends of the gas bag connect centrifugal fan and electromagnetic impulse valve respectively, and the electromagnetic impulse valve is connected with the injection tube located at upper box upper end. 
The sack cleaner is made up of bag cage with its outer filter bag being arranged;Wherein bag cage includes top cover, perpendicular muscle and circle muscle, and the circle muscle is that arc-shaped and perpendicular muscle are affixed, and the radius of the top cover is less than the radius of circle muscle, and the perpendicular muscle is connected by diagonal bar with described top cover. 
In order to be able to adjust the injection time of cleaning cycle and electromagnetic impulse valve according to actual condition, deduster is set to be run in certain range of resistance, the inside of bag type dust collector is provided with the controller for being used for detecting bag interior air-flow resistance, and the controller is electrically connected with described electromagnetic impulse valve. 
Pressure is 0.4-0.7MPa in the gas bag, and injection air quantity is 1800-2800m3/h。 
The circle muscle is made up of elastomeric material PVC or plastics. 
Distance is not less than 4cm between the two ends of the circle muscle. 
Observation and maintenance for convenience, the top of the upper box is provided with maintenance door;In order to reach more preferable dust removing effects, the sack cleaner is at least provided with two. 
The dusty gas produced in enterprise's production, which enters, to be located at except in the dust arrester directly over dirt pits, and by being distributed in after deflector in each sack cleaner, wherein dust is delayed at the surface of filter bag, and gas is passed through from bag cage and is thrown into air.When the dust on filter bag is cumulative, the resistance produced to dusty gas air-flow is also increasing, makes also to tail off by the gas flow of filter bag.To enable this dust arrester normal work to reach the purpose of dedusting, its filter bag preferably, is now accomplished by periodically clearing up the dust adsorbed on filter bag to the resistance of air-flow no more than 1200MPa.It is used for the gas-flow resistance data for detecting the controller of filter bag interior air-flow resistance and injection time, the air quantity of injection in sack cleaner by setting, one when reaching the gas-flow resistance set on controller, controller sends instruction, make the wind that centrifugal fan is produced moment generation 0.4-0.7MPa by electromagnetic impulse valve compressed air, air quantity reaches 1800-2800m3/h;This compressed air is at full speed poured in filter bag by injection tube, while and induce the surrounding air of several times filter bag is drastically expanded in moment into filter bag, and shake off to fall to be trapped in the dust on filter bag surface along with the acting in opposition of air-flow, so as to reach deashing purpose.And the dust that deduster is collected is directly fallen on belt conveyor, and recycling is transported with material.So ensure that deduster is operated under a rational working condition always, so good dedusting effect. 
Certainly, also cleaning cycle and pulse jet time can be adjusted according to actual production operating mode, deduster is run in certain range of resistance. 
The bag cage of sack cleaner in the utility model, the circle muscle being made up of the elastomeric material of arc-shaped reaches the reducing of bag cage, and making the thickness of bag cage has Telescopic, its diameter is diminished and is easily inserted filter bag when mounted, it is also less prone to damage filter bag, extends the useful life of filter bag;Then manually strut or support the diameter of bag cage greatly and stretching filter bag by elastic force, filter bag is set to be close to a bag cage, when deduster works, filter bag will not be then subjected to displacement with dedusting and the alternating change of blowback process, avoid filter bag from leaving or be close to a bag cage, reduce the caused filter bag that rubbed between bag cage and cloth bag and damage.And available for the filter bag of different inner diameters size, saved use cost.The radius of the top cover of bag cage is small and be connected by diagonal bar with perpendicular muscle, more convenient when installing filter bag to operate, and it is easy to install in place, it is to avoid the phenomenon that filter bag slides is likely to occur when using, the dust removing effects of deduster have been ensured.The bottom of perpendicular muscle is provided with upper bag hook, if long bag cage is made up of a few section bag cages engagements, the splicing facilitated between each section bag cage is installed, and has ensured the safely, securely property connected between bag cage, prevents the discrepancy between bag cage, and protect filter bag uses safety.
