Granted: 2020-06-22
Abstract: The present invention relates to a dust collection and deodorization apparatus which allows dust particles, fine dust particles, and odor components generated during a painting operation in various painting booths, together with air inside a painting booth, to pass through a filtering means and be discharged to the outside, thus removing air pollutants. In particular, a blower fan is installed in an upper space inside an apparatus housing, and in a lower space of the apparatus housing, a glass wool filter, a prefilter, an activated charcoal filter, and a carbon filter are sequentially installed so as to correspond to a flow path of gas, wherein each filter is configured as a cartridge-type filter in a form of a rectangular plate. In particular, the glass wool filter and the carbon filter are each inserted in a horizontal direction along a bottom surface and a central line of the apparatus housing. In particular, each of the prefilter and the activated charcoal filter is configured as a filtering unit formed by two filters leaning on each other with an inclination in a ″∧″ shape, wherein the filtering unit of the prefilter is inserted into the filtering unit of the activated charcoal filter, and then is disposed continuously along a space between the glass wool filter and the carbon filter. Accordingly, large-size dust particles are removed by the glass wool filter for a first time, extremely small-size particles are removed by the prefilter for a second time, and micron-size fine dust particles and odor components are finally removed by the activated charcoal filter and the carbon filter. Through the above scheme, the dust collection and deodorization apparatus efficiently distributes a treatment load for each filter, and at the same time, enables a multistep high-performance filtering operation with four or more steps while securing a sufficient filtering area even in an extremely small space.
