Pipe and device for trapping and discharging a condensate edge film for installation therein

摘要

A device in a pipe has an annular partition spaced radially inwardly from an inner face of the pipe and defining therewith an upstream annular space opening axially upstream of the direction into the pipe such that a secondary gas stream is separated from the primary gas stream along with a liquid film on the inner surface, a downstream annular space larger than the upstream annular space, and a droplet separator opening into the downstream annular space. The separator has a plurality of lamellas, a condensate sump, and a drain, so that the edge film intercepted by the partition into the upstream space passes therefrom into the downstream space and therefrom through the separator such that the liquid of the film flows into the sump and out the drain and the secondary gas stream passes out of the separator.

1. In combination with a pipe centered on an axis and through which wet flue gases of a scrubbing process pass axially as a stream in a flow direction, a device comprising:
an annular partition spaced radially inwardly from an inner face of the pipe and defining therewith an upstream annular space opening axially upstream of the direction into the pipe such that a secondary gas stream is separated from the primary gas stream along with a liquid film on the inner surface; structure at a downstream end of the partition forming a downstream annular space larger than the upstream annular space; and a droplet separator opening into the downstream annular space and having a plurality of lamellas, a condensate sump, and a drain, whereby the edge film intercepted by the partition into the upstream space passes therefrom into the downstream space and therefrom through the separator such that the liquid of the film flows into the sump and out the drain and the secondary gas stream passes out of the separator.
