Problems solved by technology

[0003] With the development of society, the application of dryers is becoming more and more extensive, including grain, tea, food, medicine, agricultural and sideline products, tobacco, traditional Chinese medicine, feed, pasture, vegetables, meat, fish, seafood, melons and fruits, preserved fruits , melon seeds, cement, chemical raw materials, paper, printed matter, printed matter, paint, clothing, drum, mine, ore, medicine residue, wine residue, fruit residue, slag, coal, metal powder, livestock manure, phosphate fertilizer, ammonium sulfate , foaming agent, light calcium carbonate, clay, magnetic powder, graphite, milk powder, rubber, leather, cloth, sludge, mud, waste residue, garbage, starch, bean products, sugar products, chemical fertilizers, etc. A dryer is used, but the efficiency of the current dryer is very low, and the hot air carrying a large amount of energy is directly discharged into the atmosphere, so it consumes a lot of energy and should be a key target for energy saving and emission reduction

no. 1 approach

[0029] figure 1 It is a schematic diagram of a waste heat recycling type high-efficiency energy-saving dryer of the present invention.

[0030] Such as figure 1 As shown, the waste heat recycling type high-efficiency energy-saving dryer of the present invention includes a high-temperature insulation cylinder assembly, a low-temperature insulation cylinder assembly, a multi-source heat pump assembly, a blower device 17, a first filter 6, a drain pipe 13, Temperature sensor (not marked in the figure), humidity sensor (not marked in the figure), frequency converter (not marked in the figure), program controller (not marked in the figure).

[0031]The high-temperature insulation cylinder assembly includes a high-temperature insulation cylinder shell 1, a high-temperature insulation cylinder insulation layer 2, a high-temperature insulation cylinder inner shell 3, a high-temperature insulation cylinder air outlet 4, a high-temperature insulation cylinder air outlet pipe 5, and a h...

no. 2 approach

[0043] figure 2 It is a schematic diagram of the second embodiment of the waste heat recycling type high-efficiency energy-saving dryer of the present invention. The second embodiment is basically the same as the first embodiment, except that a heat supplement pipe 31 and a cooling pipe 32 are added to the liquid storage tank 12, so that The heat in the liquid storage tank 12 will be continuously replenished, and the heating effect of the multi-source heat pump assembly can be guaranteed. The fluid in the supplementary heat pipe 31 can be the water of natural temperature, also can be the waste hot water that is useless, also can be the hot water that hot spring discharges, also can be other any fluid that has certain temperature. After cooling, the cooled water is drained through the cooling pipe 32 to maintain a suitable liquid level and temperature in the liquid storage tank.

no. 3 approach

[0045] image 3 It is a schematic diagram of the third embodiment of the waste heat recycling type high-efficiency energy-saving dryer of the present invention. The third embodiment is basically the same as the first embodiment, except that the heat supplementary pipe 31, the cooling pipe 32, and the supplementary heat pipe 31 are added to the liquid storage tank 12. The heat radiation pipe 33, the fluid in the heat supplement pipe 31 and the heat supplement heat dissipation pipe 33 is higher than the temperature of the liquid in the liquid storage tank 12, and the heat supplement heat dissipation pipe 33 will supplement heat to the liquid in the liquid storage tank 12, and then pass through the cooling pipe 32 flow to the designated place, only heat exchange occurs in this process, no substance exchange occurs.

Abstract

The invention discloses an efficient energy-saving drying machine which is of a waste heat recycling model, comprising a high temperature heat-preservation cylinder assembly, a low temperature heat-preservation cylinder assembly and a multi-source heatpump assembly. The machine not only uses the multi-source heatpump technology to improve the heating efficiency, but also takes the original useless hot air as heat power supply to absorb heat from hot air by utilizing a heat absorbing coil, meanwhile, the moisture of the temperature-lowed hot air is condensed into water, the air becomes drier and drier and the temperature becomes higher and higher, after the temperature reaches a seted dgree, a program controller adjusts the working frequency of a compressor by a frequency converter so as to ensure the temperature to keep an optimum temperature. In this way, all drying machines can save more than 80% electricity and the invention is certainly one of the most important energy-saving and emission-reduction measures, which is a thorough revolution of the drying machines. According to that drying all materials in the world needs 3000 billion degrees per year currently, if 80% electricity can be saved, 2400 billion degrees of electricity can be saved, 0.864 billion tons of coal can be saved and 1.4688 billion tons of carbon dioxide emission can be reduced per year.
