High-speed mixing reactor and application thereof

A rapid mixing reactor, comprising a first feed-in passage housing, a reactor housing, a second feed-in passage, a hollow blade-wheel feed distributor having lateral faces(s), a blade wheel plate, a rotation shaft, and a first feed distributor,

• wherein the first feed-in passage housing is coaxial with respect to the reactor housing and communicates with a reaction space inside the reactor housing via the first feed distributor that is set up at an end of the first feed-in passage housing;
• the second feed-in passage, the hollow blade-wheel feed distributor and the rotation shaft each are fixed in connection with each other in a sequence along the central axis of the reactor;
• the hollow blade-wheel feed distributor is located within the reactor housing and rotates axially under a driving force of the rotation shaft;
• the second feed-in passage is connected with a feed passage inside the hollow blade-wheel feed distributor;
• the first feed-in passage housing has at least one first feed-in inlet therein;
• the reactor housing has at least one reaction liquid outlet at its distal end;
• and
• the first feed distributor and the hollow blade-wheel feed distributor are provided with first feed-in jetting hole(s) and second feed-in jetting hole(s), respectively;
• wherein the second feed-in passage, the hollow blade-wheel feed distributor, and the rotation shaft are rigidly coupled in this order along the central axis of the reactor;
• wherein a dynamic seal ring and a static seal ring which can abut tightly against each other are located at the site where the hollow blade-wheel feed distributor is connected with the second feed-in passage;
• and
• the dynamic seal ring is located on the hollow blade-wheel feed distributor, and the static seal ring is located at the end of the second feed-in passage, wherein one side of the static seal ring abuts against the dynamic seal ring on the hollow blade-wheel feed distributor, and the other side of the static seal ring is fixed to the first feed distributor via, from inside to outside, an expansion joint and a spring.
