Spray dust extracting device for top floating dust on artificial-board cyclone dust extractor

Abstract

The invention discloses a spray dust extracting device for top floating dust on an artificial-board cyclone dust extracting, which comprises a room body, wherein the interior of the room body is divided into an air purifying chamber and a dust collecting chamber through an isolation wall; an airflow hole is formed on the upper part of the isolation wall; an air inlet pipe is mounted on one end of the top part of the dust collecting chamber and is extended into the dust collecting chamber; a spraying ring pipe is mounted on the outer wall of the pipe orifice of the air inlet pipe; an atomizing direction of the spraying ring pipe is towards a center; a transversely-distributed first spraying rack pipe and a longitudinally-distributed spraying pipe are orderly mounted on the top part of the dust collecting chamber between the spraying ring pipe and the airflow hole; atomizing directions of first spraying rack pipe and spraying pipe are towards a bottom board of the air purifying chamber; the top part of the air purifying chamber is articulate with an inclined-downwardly whirl plate; a second spraying rack pipe is mounted on a whirl plate; an atomizing direction of the second spraying rack pipe is towards the airflow hole; and the left end of the top part of the air purifying end is provided with an air exhaust pipe communicated with the air purifying chamber. According to the invention, secondary dust collection effect is acquired by a little of equipment investment; enterprise neighboring environment is improved greatly; and operation cost is low.

Description

Technical field: [0001] The invention relates to a wood-based panel processing technology, in particular to a floating dust and water mist dust removal device at the top of a wood-based panel cyclone dust collector. Background technique: [0002] The cyclone dust collector is a device that uses the centrifugal force generated by the rotating motion of the dust-laden airflow to separate and capture the dust particles from the gas. After the airflow enters the cyclone dust collector from the inlet, it rotates spirally from top to bottom along the outer wall. After reaching the bottom of the cone, the downwardly rotating airflow turns upward and rotates upward along the axis. When the airflow rotates, the dust particles move to the outer wall under the action of the inertial centrifugal force, and fall into the ash hopper along the wall under the joint action of the airflow and gravity, and the dust-free gas flows to the axial center area and is discharged from the exhaust core...

AI Technical Summary

Problems solved by technology

Because the bag type or other types of dust collectors are not suitable for secondary dust removal (such as the cyclone separator at the dry end of the pipeline in fiberboard production, it is not suitable for dust removal by bag dust collectors due to the large amount of water in the exhaust gas) or expensive Investment and operating costs; so that these companies mostly discharge the fine dust escaping from the cyclone dust collector directly into the atmosphere, causing huge pollution to the surrounding environment of production
