Description
Technical field
The invention belongs to the environment-friendlyanti-explosion anti-explosion method in wood processing technique field, and in particular to the anti-prosecutor that wood dust is fired
Method.
Background technology
With social city, technicalization, hommization development, wood-processing industry obtained vigorous growth, increasingly
Many timber is processed application, and the thing followed is that wood dust fires showing for problem.China's wood processing enterprise occurs every year
It is tens of or even nearly a hundred or so that dust fires event.With social construction, security developments theory and legal society construction process
Promote, the influence that dust fires to safety in production is paid much attention to by various circles of society.Each not phase of inducement that wood dust is fired
Together, but the common problem of industry.Therefore, the preventing control method that a kind of wood dust is fired is designed, to promote industrial security to give birth to
Production, is very important.
And with the popularity of humanized concept, prevention and control wood dust, which is fired, to be very important, dust fire only occur in it is outstanding
Float aerial dust be dust cloud reach finite concentration, and have extraneous factor induction under conditions of.It is static to be piled up in feed bin
In or to be deposited on the dust of solid wall surface be not possess dust to fire condition.The firing of wooden dust belongs to induction formula and fired,
Its condition fired is：The concentration of dust cloud reaches that it fires concentration accordingly；The inducement for causing and firing is there is, and is had enough
Induction energy；Firing has certain combustion adjuvant such as oxygen concentration in environment.I.e. when in indoor local space or vessel space
When the concentration of dust suspension reaches certain scope, in the case where being enough to cause the extraneous risk factor fired to act on, will occur powder
Dirt combustion explosion phenomenon.For different dust, its dust concentration fired has individual limit range, i.e. least concentration to be referred to as blast
Least concentration and maximum concentration, even if presence can cause the incitant fired, if actual dust concentration is less than LEL
Or higher than UEL, will not also induce dust and fire.The concentration of wood dust is the necessary condition that it is fired.Wood particulate reaches
25-65g/m3After can fire, dust fire the presence of inducement and with enough induction energy be its occur dust fire
Adequate condition.In the past due to a lack of the understanding and attention fired to dust, thus dust fire showing as phenomenon more it is accidental prominent
Send out sexual behavior part.Mainly there are naked light, red-hot particulate matter or surface, aggregation heat, heat ray, mechanical friction such as sand to cut and touch with regard to its inducement
Hit the spark of generation, spark that electric or static discharge is produced etc..
Dust explosion occurred for the nineties in last century, glued board sanding workshop section of Shanghai wood-based plate manufacturing enterprise dust pelletizing system
Accident.The cause of blast is that the abrasive band that sand is cut and the irony debris remained in glued board plate friction are produced caused by spark.Blast
Tempering causes operative employee to burn, and sander is badly damaged, and deduster disintegrates, and the dust room of brick mix structure collapses.In fiberboard life
In producing line, the scratch board conveyor or bucket elevator of the wooden particle of transport also once occurred dust and fired.The process fed in transporter
In, because coming off, being entrained in the bolt in wood particulate, nut etc. and transporter housing, hopper or scraper plate collision generation spark, from
And the airborne dust for inducing charging or discharge pit is fired.
Explosion accident occurs for the dust pelletizing system of southern Jiangsu furniture enterprise, and its reason is induced by electrostatic discharge spark.
In enterprise's dust pelletizing system, connecting machine tool dust shield and dust sucting pipeline all use plastic flexible pipe, and length is longer.It is swiftly flowing
Air-flow carries dry wood chip and electrostatic charge is produced when flowing through plastic flexible pipe, and is gathered on flexible pipe.Because of plastic flexible pipe
Electric conductivity extreme difference, a large amount of discharge electrostatic charges gathered, the final dust that induces is fired.On the sander of some artificial board enterprises
The dust suction interface of sand frame and the junction of dust sucting pipeline use plastic flexible pipe or rubber tube, also once produce electric discharge because electrostatic gathers
Induce dust to fire, this kind of accident also mostly occurs in the occasion that air is more dried, wooden particle moisture content is relatively low.Northeast fiber
Plate manufacturing enterprise once there occurs because of filter fabric of bag filter precipitator static discharge generation spark, produced by fiberboard sanding workshop section of having ignited
Wood-fibred dust, initial explosion occur dust pelletizing system dust-collecting bin, then cause dust in cleaning shaft and workshop
Subsequent explosion, the final fire for triggering workshop and storehouse.
It is quick-fried that the solid wooden floor board on the ground such as East China, south China is processed, a lot of dust also once occurred for the dust pelletizing system of Furniture Manufacturing Enterprise
It is fried.Its reason be many saw blade circular sawing machines of longitudinal break down in sawing hard wood, because of broached-tooth design and size is not good enough, saw blade tensioned
Degree problem, feed speed too big or sawtooth rust etc., cause saw blade binding, swage set surface local because of improper frictional heating, carbon
Change or burning sawdust particulates enter dust collection pipeline with dust-absorbing airflow, so as to cause dust to fire.The nineties in century, Hunan is artificial
Dust explosion occurs for fiberboard sanding dedusting workshop section of plate enterprise, and it is as caused by aggregation heat induced that it, which is fired,.The sand of the enterprise
Light dedusting is by primary dust removing of cyclone separator, sack cleaner is two-stage dust removal.Because two-stage dedusting still can not finally reach
Dust removing effects, enterprise is on the basis of two-stage dedusting, 1 so-called " three-level " dedusting of having been connected again in sanding dust pelletizing system, with
Improve dust removing effects.Due to adding 1 sack cleaner in original secondary dust collecting system so that the air-flow resistance of former dust pelletizing system
Power increase about 30%.By the increased influence of the resistance of ducting, the air quantity of vane centrifugal blower fan is greatly lowered, one side sweep-up pipe
The melting concn of dust is increased to 219.6g/ m in road3, in another aspect pipeline actual deficiency in draught with take away in time because
Sanding and the frictional heat produced, red-hot powder cause filter bag of dust collector to burn with air-flow, ignite the dust in deduster, and
Secondary fire is formd in pipe-line system.
