  • Patent number: 9138717
    Abstract: Disclosed is 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, a rotation shaft, and a first feed distributor, wherein the first feed-in passage housing and the reactor housing are constructed coaxially and communicated with each other; the second feed-in passage, the hollow blade-wheel feed distributor and the rotation shaft each are fixed in connection with each other in the sequence along the central axis of the reactor; the hollow blade-wheel feed distributor is located within the reactor housing and rotates axially under the driving force of the rotation shaft; the second feed-in passage is connected with the hollow blade-wheel feed distributor; the first feed-in passage housing is set up with at least one first feed-in inlet therein; the reactor housing is set up with at least one reaction liquid outlet at its distal end; and the first feed distributor and the hollow blade-wheel feed distributor are pro

  • Patent number: 8042988
    Abstract: A hole-jetting type mixer-reactor, comprises the following parts: a first feeding port, a second feeding port, an outer casing, an inner casing, jet holes and a mixing reaction zone. The inner casing is inside the outer casing, and the lower portion of the outer casing forms a buffer chamber with the inner casing. The first feeding port connects with the inner casing to constitute one flow channel, and the second feeding port connects with the buffer chamber to form the other flow channel. The jet holes are on the wall of the inner casing situated at lower portion of the buffer chamber. The mixing reaction zone is inside the inner casing below the jet holes. The cross section of the inner casing is rectangular or rectangle-like. The mixer-reactor can achieve a fast mixing of two reactant streams which reacts with instantaneous, complicated parallel or consecutive competing reactions. The time scale of the mixing process is several milliseconds.
