It is sensitive, 1/10 to ten percent the time required to conventional heating methods is only needed, and also without hysteresis quality after closing；Secondly micro-
Wave has very strong penetration capacity, not begins to warm up from the surface of material, but from all directions balancedly penetrable material
After be evenly heated, so heat source can not directly be contacted with material, and be directed through media interior in the form of an electromagnetic wave；It is micro-
Wave energy is enough integrally to heat substance inside, can be evenly heated substance, realizes " no temperature gradient heating ".
Based on the above, microwave heating can make, material inside and outside is heated evenly or even internal temperature is higher, compared to conventional pyrolysis
Mode, microwave-heating have higher controllability, high energy efficiency, economy, more saving pyrolysis time and energy, are that substitution works as forward pass
System pyrolysis way is used to handle and dispose the ideal chose of waste.This just handles organic polluted soil for microwave-heating and provides
The feasibility of theoretical basis advantage and reality.
