Description
Technical field
The present invention relates to the technical field of mechanical equipment, specifically a kind of bagasse multistage drying cleaning combustion system.
Background technique
Chinese Government is to whole world solemn commitment on the World Climate Conference of Copenhagen within 2009, to the year two thousand twenty China list
Position GDP CO2 emission decline 40%~45% in than 2005；China's haze weather duration is continuous in recent years
Elongated, the principal element of influence is power plant, vehicle exhaust and industrial fumes, and nitrogen oxides and flue dust are the main members to form haze
Act of violence, the boiler of sugar manufacturing industry is using biomass --- for bagasse as fuel, flue gas emission is also influence factor therein.Sugar refinery
The bagasse moisture content 45-50% of milling shop discharge, the bagasse overwhelming majority are used as boiler oil burning and are directly entered boiler
Interior burning, the boiler of current each sugar enterprise is due to remaining in the lower operation of old Theory of Combustion guidance, and environmental protection facility is big in addition
Part is all the dust pelletizing system based on water film dedusting, and denitrification system is almost without foundation, absolutely the major part below standard row in sugar refinery
It puts.A big chunk moisture contained by bagasse can be only achieved the ignition point of bagasse, shadow after need to being also evaporated in boiler furnace
The fire box temperature for having rung boiler, reduces boiler combustion efficiency.Some bagasse end energy completely burned is just carried over furnace
Outside, fuel is wasted significantly, is unfavorable for energy-saving.In addition big and heavy bagasse enters burner hearth cannot form suspended state completely, be
It using low-NO_x combustion technology, realizes the double technical bottlenecks up to standard of bagasse boiler flue gas emission, is that current sugar enterprise is badly in need of solving
Technical problem.
Once development and application bagasse dry technology is more in China sugar refinery, mainly uses chimneying drying, pneumatic conveying drying, returns
The methods of transfer roller cartridge type, superheat steam drying, cyclone type, helical feed flue gas formula, but there are technical errors more, pipeline
Blocking, the disadvantages of production safety rate is low, drying efficiency is not high, there is presently no the mature technologies of normal operation.Include in bagasse
The ingredients such as cellulose, lignin, sugarcane marrow, main component are cellulose.The degree of cross linking between cellulose is strong, and bagasse is caused to be easy knot
Group, does not can be uniformly dispersed in burner, cannot form suspended state in boiler, prevent it from being fully burned.
