Micro-channel reactor

The invention relates to the technical field of chemical equipment, in particular to a micro-channel reactor which comprises a first reaction plate, a second reaction plate, a third reaction plate and a fourth reaction plate. The second reaction plate and the first reaction plate are arranged in a stacked mode, the second reaction plate is provided with a second unit mixing area, the second unit mixing area is provided with a second reaction channel, and the second reaction channel is communicated with the first reaction channel; the adjusting assembly is provided with a force application part, and the force application part is arranged on at least one side of the second reaction plate so as to apply force to the second reaction plate, so that the second reaction plate and the first reaction plate move relatively, the communication area of the second reaction channel and the first reaction channel is changed, and the flux of the micro-channel reactor is further adjusted; the communication area of the second r
