Background technology
Along with the depletion and the environmental pollution of resource are serious day by day, countries in the world are all towards the target of setting up a conservation-minded society and effort, the vital task that energy-saving and emission-reduction are pendulum in face of we everyone.
Development along with society, the application of dryer is more and more extensive, comprise grain, tealeaves, food, medicine, agricultural byproducts, tobacco, Chinese medicine, feed, herbage, vegetables, meat, fish, seafood, melon and fruit, preserved fruit, melon seeds, cement, industrial chemicals, paper, dyeing material, printed matter, paint, clothing, rotating cylinder, the mine, ore, the dregs of a decoction, schlempe, pomace, slag, coal, metal dust, feces of livestock and poultry, phosphate fertilizer, the sulphur ammonium, blowing agent, precipitated calcium carbonate, carclazyte, magnetic, graphite, milk powder, rubber, leather, cloth, mud, mud, waste residue, rubbish, starch, bean product, the carbohydrate goods, dryer is all extensively adopted in the oven dry of chemical fertilizer etc., but the efficient of dryer is very low at present, the hot-air that has carried big energy directly is discharged in the atmosphere, so special power consumption should be as the highest priority of energy-saving and emission-reduction.
For example the foodstuff drying device that extensively adopts consumes lot of energy, demarcation by the foodstuff drying device of certain company: oven dry 50kg finished product of grain needs power consumption 7.5 degree, promptly quite consume 150 degree with oven dry one ton-grain food, there is 3,000,000,000 ton-grain food to need oven dry by the whole world, then annual power consumption 4,500 hundred million degree, conversion consumption 16,200 ten thousand tons in coal (every degree power consumption coal 360g) is equivalent to 27,540 ten thousand tons of earth row carbon dioxide.If can economize on electricity 80%, 3,600 hundred million degree that then can economize on electricity can be economized on coal 12,960 ten thousand tons, but 22,032 ten thousand tons of reducing emission of carbon dioxide.
The family of developed country 76% such as American-European-Japanese has used dryer (containing the washing machine of being with clothes drying function), but the efficient of dryer is low especially, the parameter that provides according to certain international top-brand NH45-19T model dryer products instruction, the power of dryer is 1280W, oven dry 4.5kg clothing needs 165 minutes consuming time, like this power consumption is reached 3.5 degree (kwh), by the annual work of every dryer 120 times, about 500,000,000 of whole world dryer (containing the washing machine of being with clothes drying function), then annual drying power consumption 2,100 hundred million degree, conversion consumption 7,560 ten thousand tons in coal (every degree power consumption coal 360g), be equivalent to 12,852 ten thousand tons of earth row carbon dioxide, if can economize on electricity 80%, 1680 degree then can economize on electricity, can economize on coal 6,028 ten thousand tons, but 10,281 ten thousand tons of reducing emission of carbon dioxide.
The power consumption of other dryer is also quite surprising, and concrete power consumption situation is here given unnecessary details no longer one by one; The total power consumption of all dryers estimates to surpass 30,000 hundred million degree.
