Apparatus for the static mixing of fluid streams

A mixing insert which comprises at least two plates provided with webs defining slots therebetween, the webs of one plate extending crosswise through the slots of at least one other plate which is set at an angle to the first plate, said insert being suitable for insertion into a pipe to provide static mixing of a stream of fluid flowing in the pipe and wherein the plates are provided with wwbs which taper stepwise.

A mixing insert which comprises at least two plates provided with webs defining slots therebetween, the webs of one plate extending crosswise through the slots of at least one other plate which is set at an angle to the first plate, said insert being suitable for insertion into a pipe to provide static mixing of a stream of fluid flowing in the pipe in which the plates are in the form of combs and have elliptical circumferences.

A mixing insert which comprises at least two plates in the form of combs provided with webs defining slots therebetween, the webs of one plate extending crosswise through the slots of at least one other plate which is set at an angle to the first plate, said insert being suitable for insertion into a pipe so that each plate makes contact all along its circumference inside of the pipe, and, being effective to provide static mixing of a stream of fluid flowing in the pipe by subdivision of the stream.

Apparatus for the static mixing of a fluid stream which comprises a pipe provided with at least one mixing insert which comprises a first group of spaced webs disposed so as to define slots between the webs, and a second group of spaced webs also disposed as to define slots between the webs, the webs of one of said groups extending crosswise through the slots of the other of said groups, said first and second group of webs being mounted in the pipe inclined at an angle to the axis of the pipe for static mixing of a fluid stream passed through the pipe.
