Abstract

A spray booth with a dry separating system, in which liquid repaint material is removed from sucked up air during spraying of liquid material. Its filtration system consists of three degrees of filtration, whereas the first level is formed by a shutter (3), the second a filtration wall (4) and the third by large-area suspension filters (5).<IMAGE>

Description

BACKGROUND OF THE INVENTION The present invention relates to a spray booth with a dry separation system which separates liquid mass overspray from the exhaust air when spraying liquid masses.

Heretofore, a spray booth with a different embodiment of a separation system is used for separating overspray of sprayed liquid masses from the exhaust air of the spray booth. The purpose of these systems is to ensure sufficient exhaustion of the liquid mass spray area and to eliminate liquid mass sprays from the exhaust air.

Several methods have been proposed to solve the above problem. Two separation methods are commonly used. Wet separation method and dry separation method. The wet separation method involves mixing the overspray with water while simultaneously acting with chemical agents. This method requires complex and demanding waste water disposal, frequent replacement and complex cleaning of the entire system. The method is also very energy intensive. The dry separation method involves trapping overspray on dry filter materials. However, the filter materials used hitherto have a low separating capacity. Unsupported sprays thus escape into the open air, resulting in negative ecological consequences. At the same time, the safety of the entire system is also compromised.

The above-mentioned disadvantages of the prior art are eliminated by a spray booth with a dry separating system, characterized in that a dry separating system consisting of louvers, a filter wall and large pocket filters is located between the suction fan and the liquid spray area. The blinds are preferably composed of three consecutive slats.

can be achieved by high pelletizing by separating filtration. The first stage of the flow direction is extracted

Advantages of the invention reside in the fact that the fluidity of the overspray of liquid materials is clear. This conveying system is divided into three stages formed by louvers, air massive part is formed by a filter wall, passed through the first stage of spraying of liquid masses, the filtration degree, constituted by the main advantage of the invention consists in low energy demands and simple operation and maintenance.

divided into the trapping effect of changes of overflows of liquid masses. The second stage catching liquid spray, filtration. Perfect separation of the remaining from the exhausted air is ensured by the third large-size pocket filters. Not the whole separation system

The accompanying drawing shows schematically an exemplary embodiment of a spray booth with a dry separation system. Figure 1 is a cross-sectional side view of the cab; Figure 2 is a cross-sectional plan view of the cab.

From the spraying area of the liquid masses 1, the ventilator 2 sucks off the air mass - spraying the liquid masses through a dry separating system consisting of louvers 3, a filter wall 4 and large-area filters 5. The louvers 2 consist of individual slats 2 ·
