Overall demand is high thermal efficiency, low energy consumption, simple configuration, easy to control, small footprint, operating environment health and safety. At present, the salt industry to use more common drying equipment: rotary tube dryer, indirectly heated rotary dryers, disc continuous dryer, air dryer (divided pulse airflow, air rotary, positive and negative two air drying ), spin flash dryers, rotary drum dryer, spray dryer (divided granulated, powdered, centrifugal, pressure), vibration fluidized bed dryer, static vacuum dryer, hot air circulation oven, rake , paddle vacuum dryer, fluid bed dryer (horizontal and vertical), etc. These drying equipment for product quality to provide a guarantee, but there are exhaust collect "dust" problem. Due to the increasing nanoscale products, more and more original fine particle size, moisture content increase potential paste materials, companies continue to add to the large-scale, large-scale development, enterprise eager combination drying equipment. In particular, some large-tonnage products, such as precipitated calcium carbonate, the current national production of 300 million tons, the smallest of the production line with an annual output 10,000 tons, 100,000 tons of scale to be five sets of drying equipment, Guangxi, a business plan to get 500,000 tons, At the current level of drying equipment, regardless of the area of ??the exhaust gas after drying equipment or product revenue "dust" is a big amount. Widely used in accordance with current industry pulse bag filter, the operating environment is very harsh, we must take effective measures to solve them. Therefore, we want the device to the research unit focused on solving two problems, one is the high water content of the paste dry fine objects problem, and second, after the body dry exhaust collect "dust" industrial hygiene problems. Still calcium carbonate industry, for example, of the more than 200 companies in the drying equipment selection, basic use of indirect heating rotary dryers, continuous tray dryers, rotary tube dryer, etc., to be met, although productivity, energy consumption and exhaust revenue "dust" is not ideal, into calcium carbonate business from the ground to the roof are covered with a layer of white calcium carbonate powder, even the tables and chairs in the office is also a layer of white, this area has a management problem More importantly, after the dry exhaust collect "dust", but off. The industry has recently introduced the DuPont company's dust removal equipment, basically solved the problem. Therefore, the combination of drying equipment should include: providing a heat source equipment, primary and secondary drying equipment, exhaust collect "dust" equipment, hope equipment manufacturing, research units fuss high thermal efficiency, low energy consumption, simple configuration, easy to control, etc. In a combination of drying equipment to make a fuss, service to others, to develop themselves. If the dry calcium carbonate industry to solve the problem, and to achieve a high efficiency equipment, environment-friendly, like other varieties of dry problem solved.
