Fish-shaped microreactor

The invention discloses a fish-shaped microreactor, and relates to the technical field of reaction equipment, the fish-shaped microreactor comprises a reaction plate, the reaction plate is provided with a feeding flow channel, a discharging flow channel and a plurality of reaction units, each reaction unit is divided into an upper layer flow channel and a lower layer flow channel, and each layer flow channel comprises a partition wall of a fan-shaped structure and an oval baffle arranged behind the partition wall. And the deflection baffles are arranged in a staggered manner. And the cross flow alternation of the two layers of runners is realized through holes formed in the middle-layer plate. Each reaction unit is provided with a partition wall with two fan-shaped structures and an elliptical baffle plate so as to realize shunting and converging of fluid, and contraction and release flow channels are arranged between flow channels on two sides of the partition wall with the two fan-shaped structures and the
