Description

UV paint dust collection device

technical field

The invention relates to a UV paint dust collection device, in particular to a UV paint dust collection device which can improve the dust collection efficiency of dust containing a large amount of mucus-like components and is easy to maintain the dust collection equipment.

Background technique

The so-called UV paint refers to the paint whose coating film is hardened under the action of ultraviolet rays (Ultra Violet). The UV paint is widely used in the painting operations of wood, plastic, paper, PVC, etc. that are prone to thermal deformation.

In addition, the space occupied by the painting equipment is small, and drying heat is not required for curing, so it is not only energy-saving, but also environmentally friendly without solvents.

However, although the UV paint is environmentally friendly, the paint dust gas produced during the product painting operation not only seriously pollutes the atmosphere, but also is harmful to the health of the operator. Therefore, it is necessary to install Dust collection device for paint dust.

As shown in Figure 1, the dust collector of existing UV paint dust is supplied by the conduit 10 of UV paint dust gas from UV painting equipment, the air blower 20 that introduces UV paint dust gas forcibly through the conduit, and the air blower forcibly The introduced UV paint dust gas imparts centrifugal force to remove particulate matter centrifugal force dust collector 30, and the activated carbon adsorber 40 for secondary adsorption treatment of the fine UV paint dust gas that removes particulate matter is discharged into the atmosphere.

But, described UV paint dust gas is in the process that moves by conduit on its material characteristic, because mutually agglomerates and becomes slime, therefore, in the dust collection device of existing UV paint dust, becomes the UV paint dust of slime The gas adsorbs on the activated carbon adsorber to increase the pressure loss, and the mucus-like UV paint dust gas blocks the air gap of the activated carbon and cannot play an adsorption role. For this, in the consistent dust collection process, after the activated carbon adsorber is eliminated, Just start described dust collecting device etc., have quite serious problem on the use structure.

As mentioned above, the existing UV paint dust collection device is composed of a cleaning dust collector instead of an activated carbon adsorber as required, so there is often a situation of selective utilization, but because this cleaning dust collector is only suitable for handling soluble dust gas Composition, the UV paint dust gas insoluble in cleaning water cannot be adsorbed and purified. Therefore, the UV paint dust gas generated in the UV paint equipment is still discharged into the atmosphere, polluting the precious environment, etc., which still has serious problems in treatment efficiency.

That is, the above-mentioned conventional UV paint dust collector must be equipped with a centrifugal force dust collector and an activated carbon adsorber, and thus has a problem of increased cost burden.

In addition, there is a problem that the dust collection process is difficult for the viscous dust that becomes viscous during the process of flowing in through the duct. Therefore, the dust collection process cannot be smoothly carried out for UV paint dust containing a large amount of viscous components, and the dust collection efficiency is high. Lowering the problem.
