1. a nozzle, it can be used for being injected in olefin polymerization reactor by catalyst solution or catalyst pulp, and described nozzle is made up of following:

  • First pipeline, it includes main body, transition portion and injects end;

    Second pipe, it has inner surface and outer surface, wherein said first pipeline is arranged around described second pipe, to define first annular space between the two at the first pipeline and second pipe, and wherein said second pipe includes the radial and axial spaced apart multiple apertures around this second pipe;

    AndSupporting member, it is arranged at least partially about the outer surface of described first pipeline, to define the second annular space between the two at supporting member and the first pipeline, described supporting member has the outer surface of contraction at its first end place, wherein, the described injection end of described first pipeline extends 0.5 inch to about 1 inch from the described first end of described supporting memberWherein, one or more spaced radial things are arranged in described second annular space, 0.5 inch to 3 inches location of the end of nozzle described in wherein said spaced radial object distance, wherein spaced radial thing keeps the fixed range between described first pipeline and described supporting member at the duration of work of described nozzle, and thin to avoid the stream stopping or hindering in the second annular space.
