Description
Technical field
The invention belongs to material drying technology field, the system of before specifically utilizing bagasse making sheet, bagasse being dried.
Background technology
Along with the enforcement of the enhancing of consumption of resident ability and the transformation of consumption idea and wildwood protected project, new growth peak will be welcome at industry-by-industries such as furniture, building, decoration, packaging, shipbuilding, automobiles to the demand of fiberboard.
Furniture is the required consumer goods of people, and as global Furniture manufacturing center, leap to No. 1 in the world as far back as the China Furniture Industry output value in 2006,1/5th of global furniture total trade volume is completed by China.The above enterprise of National Furniture scale in 2009 total industrial output value reaches 3,409 hundred million yuan, has increased by 13.5% on a year-on-year basis.The gross output value of the whole industry is greatly about about 7,300 hundred million yuans.The 1-11 month in 2010, furniture manufacturing industry income from sales total value reaches 3793.079 hundred million yuan, increases by 30.77% on a year-on-year basis; Furniture manufacturing industry total profit reaches 186.080 hundred million yuan, increases by 46.80% on a year-on-year basis.2011, China's furniture and part export amount thereof were 379.4 hundred million dollars, increase by 15% than the same period in 2010.Along with the development of housing industry, no matter be as impregnated paper veneer laminate flooring base material, still make concrete blinding, materials for wall, fiberboard application space is wide, and market potential is huge.Within following significant period of time, China's fiberboard output will increase by continued smooth.
Large-scale public building decoration such as the interior decoration sheet material consumptions such as theater, office building, market are 3-4 times of construction area, hotel, apartment, house etc. are 5-6 times, the multiplex solid wood board of these materials, core-board, glued board, cost height consumes the forest reserves again, if have 30% to replace with bagasse pressuring template, domestic market share can reach billions of unit every year.
In addition, the principles and policies of national a series of expansion domestic demand, guarantor's growth, tune structure, the heavy people's livelihood also will promote the development of fiberboard industry.And in sugarcane producing region, bagasse is the accessory substance in cane sugar manufacture process, how processing bagasse is also the problem needing to solve.At present, bagasse is mainly as the raw material of papermaking, boiler oil and fiberboard.Bagasse manufacture fiberboard completes primarily of the making sheet workshop in sugar refinery, and bagasse needs to dry bagasse before being used for making sheet, oven dry dries the water content of bagasse more than 20% to 5-9% water content, and the flue gas that the oven dry of bagasse mainly utilizes hot-blast stove to produce is dried bagasse.
In traditional drying system, bagasse raw material directly enters primary drying blast system from wet feed storehouse, understands some cold wind and be inevitably mixed in drying system in process of pneumatic transmission, reduces effluent gas temperature, drying property is reduced, and drying effect receives impact.In order to ensure that the traditional way of drying effect raises hot-blast furnace temperature, although the method also can reach the drying effect meeting technological requirement, but also can increase as the firewood consumption of fuel, disagree with " energy-saving and emission-reduction " advocated now, how to reduce before utilizing bagasse making sheet power consumption again can by bagasse dry to the water content meeting technological requirement be a current difficult problem.Open source literature also reports the drying plant of bagasse, such as:
