The cooling device 12 includes a cooling barrel 120, a condenser 121, a block 122 and a condensation port 123. The cooling barrel 120 is arranged inside the shell of the reactor 1. The cooling barrel 120 is formed by reducing the size of the reactor 1 in proportion. The block 122 is fixedly installed in the cooling barrel 12 0 is formed on the inner wall of the reactor 1.
