Description

The oven dry of viscose and adjusting device
Technical field
The utility model relates to a kind of oven dry and adjusting device of viscose.
Background technology
Viscose is regarded as high pollution, highly energy-consuming, expensive industry always, China's viscose output accounts for 60% of world wide production at present, the energy consumption and the blowdown that bring thus increase, and energy consumption and environmental issue become one of further fast-developing " bottleneck " property problem of restriction China viscose glue industry.Wherein, the whole energy consumption level of viscose glue industry exceeds 10~30% than international most advanced level, and also there are a lot of problems in this external disposal of waste gas, water and industrial residue aspect.Therefore, energy-conservation, reduction of discharging has become the core work of viscose glue industry sustainable development.
In the viscose industry, dryer is one of highly energy-consuming equipment, it also is the emphasis of energy-saving and emission-reduction, what usually adopt at present is common warm-air type dryer, dry 1 ton of viscose and consume approximately 2.8 tons of steam, the dried tail gas temperature is about 110 ℃, and water vapour content accounts for 60~70%, the direct emptying one side of tail gas that carries a large amount of waste heats causes huge energy waste, causes on the other hand serious environmental pollution.
Curtain formula or drying cylinder formula drying machine subregion stage drying are adopted in the oven dry of viscose and adjusting usually, and proparea drying medium temperature is 70~100 ℃; 100~120 ℃ in middle district; 60~70 ℃ of back zones; Then enter the damping stage.Shredding wet fiber deliver on the sheet convoying curtain to machine by feeding, about 100 millimeters of fiber floor height on the maintenance convoying curtain, translational speed is 0.82~3.7 m/min, pressure fan blasts fresh air, air-heater blasts high steam simultaneously, by being discharged by exhaust fan after the repeated multiple times circulation of circulating fan, this drying course mesohigh vapours plays the effect that heat temperature raising makes the moisture gasification again, and fresh air works the wet effect of taking.Dried tail gas can't effectively carry out waste heat recovery in this traditional drying system, its main cause has two aspects: first, the drying medium that utilizes in these three sections is the mist of steam and air, dried tail gas contains a large amount of incoagulable gas, and air specific heat is little, has assembled heat exchanger and also only can reclaim fraction dried tail gas sensible heat afterwards; The second, can carry capillary fiber secretly in the drying course dried tail gas of viscose, if assemble common fin-tube heat exchanger, capillary fiber can accumulate on the fin, passage and reduction surface film thermal conductance.Therefore, dried tail gas waste heat can't effectively reclaim in the existing viscose stoving process, has caused great energy waste.
The utility model content
