Low-rank coal pyrolysis reaction system based on electromagnetic induction rapid heating

The invention discloses a low-rank coal pyrolysis reaction system based on electromagnetic induction rapid heating. Comprising a pyrolytic reaction unit, an electromagnetic induction heating unit used for providing a heat source for the pyrolytic reaction unit, an oil-gas separation and collection unit connected with the pyrolytic reaction unit and used for collecting and separating oil gas generated by pyrolysis, and a control unit used for controlling the pyrolytic reaction. According to the system, the whole process from coal pyrolysis to oil-gas separation and residue collection is greatly simplified by integrating the spiral pyrolysis reaction unit, the electromagnetic induction heating unit and the oil-gas separation and collection unit. Meanwhile, an internal heating type electromagnetic induction heating technology is adopted, an alternating magnetic field is controlled through heating frequency and current, so that the heating temperature is accurately controlled, escape of pyrolysis volatile compone
