Abstract
The design and fabrication of an economical air filter is for an industrial cupola furnace in MIDC, Hingna. The purpose of an industrial filter is to remove unburned coal particles’ hazardous fumes and reduce NOX in the environment. The filtration system consists of a filter box that comprises four filter media which are placed vertically like a cartridge. The first media is manufactured like a frame containing a steel wool scrubber. This frame traps hot gases and large particles of smoke. The second frame contains a layer of blue silica gel that absorbs moisture present in polluted air. The third filter frame consists of activated carbon which has chemical properties for the adsorption of Carbon dioxide and Nitrogen dioxide gases. The last filter is HEPA (high-efficiency particulate air) filter, which is made from element paper. It can filter 0.3μm diameter of dust particles. Finally, we get the filtered air through the exhaust. This filtration system is effective in terms of cost, cleaning, and maintenance. The filters are easy to remove when the dust gets chocked in it, also clean easily with the help of a pneumatic gun or some dust cleaning system. This will be economical and easy to maintain.
