Waste heat cyclic utilization type high-efficiency energy-saving drying machine

Abstract

The invention discloses an energy-efficient dryer featuring recyclable use of exhaust heat, comprising a high-temperature insulated cylinder assembly, a low temperature insulated cylinder assembly and a multi-source heat pump assembly. In the invention, the multi-source heat pump technology is adopted to improve heat efficiency, most importantly, previously unused hot air is used as a heat source, a heat absorption pipe coil is adopted to absorb heat in the hot air, meanwhile, moisture of the cooled hot air is condensed to water, as a result, the air is increasingly drier and the temperature is increasingly higher, when the temperature reaches the set value, a programming controller is adopted to regulate working frequency of a compressor via a frequency converter to keep the temperature optimal. By doing so, all driers can save electricity by over 80%, according to the annual consumption of 3 trillion kilowatt-hour of electricity for drying all objects in the world, if the electricity can be saved by 80%, then 2.4 trillion kilowatt-hour of electricity and 864 million tons of coal can be saved annually, which means carbon dioxide emission can be reduced by 1,468,800,000 tons.
