K E M A C PULSE JET DUST COLLECTOR • Since 1978 * No moving parts. Compact. Easy to install and maintain. • Fully automatic and self cleaning. * Applicable to a wide range of industries offering solutions to process control and in plant dust control problems. • Designed together with you, for you, to suit the conditions unique to your plant. • Kemac’s service start from planning to drawing board and right to the fully installed dust control system. THE DUST COLLECTOR The Kemac pulse jet dust collector is a continuous automatic self cleaning unit employing the most popular, successful and the latest cleaning technique used by most well known fabric dust collector manufacturers in the world. The superior cleaning technique enable it to be used with higher filter velocity resulting in less filter bags to maintain and replace. Also being a smaller unit, it occupies less productive floor space compared to other types of fabric collectors. PRINCIPLE OF OPERATIONS An exhaust fan pulls the dust laden air into the hopper section of the dust collector where preseparated large dust particulars drop out of the air stream. The fines are trapped on the surface of the fabric. The filtered air flows through the filters into the plenum chamber and then through the fan to the atmosphere. The cleaning of these filters is done by pulses of compressed air fired into the filters via a venturi. An electronic timer regulates the cleaning frequency and cleaning time which occurs in a fraction of a second. Each bank of filters is cleaned in a repetitive sequential order. During cleaning, a short pulse of compressed air is fired into the venturi which induces a large volume of secondary filtered air from the neighbouring filters to flow into the filter being cleaned. The flow of air result on three cleaning actions occuring in a fraction of a second. a) ‘Shock’ cleaning by vibrations generated. b) Flexing of the filter media. c) Reverse flow of air from the clean air side to the dirty air side removes trapped particles in the fabric and temporarily lubricates the filter surface allowing dust cakes to slide down the side to the hopper below. FEATURES Standardisation to world standards on filter fabric type and size, and control valves have been achieved on Kemac dust collectors to enable end users easy access to Spare parts. Also standard size dust collectors are available if required. The outstanding features of Kemac dust collectors are: • No internal moving parts – eliminating valves and bearings which require regular maintenance and often problematic. • All filters type used are needle loom felt material Individually selected to suit acidic, alkaline, humid, hot conditions. e.g. polyester, polpropylene, nomex, teflon, fibre glass etc. • Large hinged access doors are provided for maintenance and access to the sock chamber. • The housing is made of heavy gauge material in mild steel, stainless or aluminium and reinforced suitably to provide a strong housing for the filters. The unit is of welded construction and easily assembled. No major assembly need be done on site. Each individual unit is designed to suit local conditions. • The timer is weather proofed and the solenoid valve coil is encapsulated in nylon to withstand hot humid conditions. • It uses a solid state timer with no moving parts. All control I.Cs are mounted on an interchangeable printed circuit board. • The unit can handle dust streams with temperature Well beyong 500 degree F. • Compressed air usage is minimum because of the venturi action. OPTIONAL • Top removal filter type are available • Round and flat types are designed to overcome Space limitations and applications. • Accessories available: Cast iron rotary valve Solids level controller Electromagnetic vibrator Vibrator mootors Fluidisation padas SIZING OF DUST COLLECTOR Each Kemac dust collector is individually sized, designed and custom built to suit each individual plant/process application taking into consideration several factors like temperature, moisture content, humidity of the air, type of material, particle size, dust loading, application, other gases involved, space limitations and emission standard. This ensures that you are getting the dust collector best suited for the duty it is required to perform. APPLICATIONS These units are used both as a process equipment to collect powder from an air conveying system and also as a means of air pollution control of dust and fumes of micron size. It has wide applications in industry related to the following materials. Aluminium Dolomite Milk powder oxide Alfafa Epoxy resin Oat flour Asbestos Feed mash Oat products Barley Feed mill dust Paper Bentonite Felspar Pebble lime Bone meals Fertilizer Puffed rice Calcium Fibre glass Puffed wheat carbonate Candy sugar Filter clay Phenolic resins Carbon black Fish flour Phosphate rock Cereal Flour Plastic powder Cement Fruit sugar Rubber Charcoal Gelatin Sand Chemicals Glue Sawdust Cocoa powder Glue binder Soya bean meal Coke Gluten meal Steel grinding Corn meal Gypsum Sugar Corn starch Hydrated lime Talc Dextrose sugar Insecticide dust Tobacco Detergent Iron oxide Tea Dried blood Lime Vitamin fines Dried oats Lead Wood dusts Dried mix cereal Mixed feeds Zinc oxide OTHER AIR POLLUTION CONTROL PRODUCTS Mechanical/manual shake fabric dust Collector Reverse air type dust collector High efficiency cyclones Scrubbers |
