Description
Technical field:
The present invention relates to wood-based plate process technology, relate in particular to a kind of wood-based plate cyclone dust collectors top floating dust Water-fog dusting apparatus.
Background technology:
Cyclone dust collectors be utilize dust-contained airflow rotate produce centrifugal force grit is separated from gas and traps the device getting off.Air-flow, from import enters cyclone dust collectors, moves as spiral rotating from top to bottom along outer wall, and the air-flow that this strand is rotated down arrives after cone base, then upwards, rotates up along axle center.When air-flow rotates, grit moves down to outer wall in the effect of centrifugal inertial force, and under air-flow and gravity acting in conjunction, along the wall people's ash bucket that falls, the gas of having removed dust converges is discharged by exhaust core pipe to central core region.
Domestic artificial board enterprise aborning, generally adopts cyclone dust collectors to realize wood fibre wind-force and carries gathering dust of end separation or production environment.For the grit of collecting more than 5～10 μ m, its efficiency of dust collection can reach 90% left and right.Due to the deduster of cloth-bag type or other pattern or be not suitable for final dusting (as inapplicable with sack cleaner dedusting again because containing a large amount of moisture content in exhaust in pipeline drying end cyclone separator in Fibreboard Production) or expensive investment, operating cost burden; Be directly to enter atmosphere to making these enterprises mostly for the micronic dust of escaping from cyclone dust collectors, cause the huge pollution to production surrounding enviroment.
Summary of the invention:
In order to solve prior art problem, the object of this invention is to provide a kind of wood-based plate cyclone dust collectors top floating dust Water-fog dusting apparatus, reasonable in design, has improved production environment.
Technical scheme of the present invention is as follows:
Wood-based plate cyclone dust collectors top floating dust Water-fog dusting apparatus, it is characterized in that: comprise room body, in room body, be divided into air-purifying chamber and dust chamber by divider wall, divider wall top has airflow hole, described one end, dust chamber top is provided with stretches into air inlet pipe inner and cyclone dust collectors blast pipe blast pipe UNICOM, on air inlet pipe mouth of pipe outer wall, spraying ring pipe is installed, the spray direction of spraying ring pipe is towards center, between spraying ring pipe and airflow hole dust chamber top the first spray row of tubes of cross direction profiles is installed successively, the shower longitudinally distributing, the first spray row of tubes, shower spray direction is towards air-purifying chamber base plate, described air-purifying chamber top is hinged is provided with the deflection plate under oblique, and the second spray row of tubes is installed on deflection plate, and the second spray row of tubes spray direction is towards airflow hole, and the left end at described air-purifying chamber top is provided with the blast pipe with air-purifying chamber UNICOM.
Described wood-based plate cyclone dust collectors top floating dust Water-fog dusting apparatus, is characterized in that: the oral area that described air inlet pipe stretches in dust chamber is horn mouth.
Described wood-based plate cyclone dust collectors top floating dust Water-fog dusting apparatus, is characterized in that: described spraying ring pipe is by upper and lower two groups.
Described wood-based plate cyclone dust collectors top floating dust Water-fog dusting apparatus, is characterized in that: described dust chamber front end one side is also provided with clamshell doors.
Described wood-based plate cyclone dust collectors top floating dust Water-fog dusting apparatus, is characterized in that: described dust chamber front end is positioned at clamshell doors opposite side and is also provided with discharger.
Described wood-based plate cyclone dust collectors top floating dust Water-fog dusting apparatus, is characterized in that: described interval, shower lower end is provided with spherical shower nozzle, and spherical shower nozzle lower surface has arc spout.
Described wood-based plate cyclone dust collectors top floating dust Water-fog dusting apparatus, is characterized in that: the inwall of described blast pipe is provided with spaced apart conical baffled.
Advantage of the present invention is:
The present invention obtains with less equipment (facility) investment the effect that secondary gathers dust.To process 60,000 m
3/ hr. ash-laden gas flow calculates, and equipment (facility) expense is (containing self-emptying device) in 20,000 left and right.
The present invention provides a kind of Regulations of simple possible to business processes cyclone dust collectors top floating dust, improved admirably enterprise's surrounding enviroment.Little and the operation and maintenance cost of equipment investment is low is suitable for the secondary processing of gathering dust, and optimizes production environment.
Operating cost of the present invention is low.Process 60,000 m
3/ hr. floating dust throughput, consumes about 3 yuan/hour of water rates, well below sack cleaner system operation and maintenance expense.Because water consumption is few, most ofly after spraying absorbed by floating dust, minimum water liquid with laying dust discharging after natural air drying, can not produce new wastewater treatment workload.
