TH18720A - The diffuser device for the downward flow reactor with multiple bed. - Google Patents

Abstract

This invention provides a device that is a diffuser. To serve to distribute liquids and The gas flowing in the multi-bed downward flow reactor consists of (1) mostly horizontally placed collector trays. This tray provides a central channel for gas to flow, which is surrounded by the dam ridge. And there is a channel for the liquid to pass through around the dam ridge (2). Spread trays are mostly placed horizontally. The tray is located under the collection tray, where the distribution tray provides a number of downward-flow tubes for the liquid and gas to flow downward. (3) The fluid divert (4) Mixing chamber, located between the collection pan and distribution tray (5) Open end guide tube. Which has the first end and the second end Which one end will connect to Funnel for liquid to pass through the collection tray And the second end opens into the mixing chamber And which ends at These two are positioned so that during normal operation There will be a stream of liquid flowing out. From this second end collided Downstream type reactor The multi-bed reactor includes a diffuser device and a multi-bed downward flow reactor. In processes involving hydrocarbons

Claims (9)

1. a diffuser device For dispersing liquids and gases in flow reactors. Downstairs with multiple bakes, including (1) a collection tray that rests mostly horizontally. Which this tray provides a channel for gas to flow Pass in the middle Which is surrounded by the dam ridge And there is a channel for the liquid to pass through around the dam ridge (2). Spread trays are mostly placed horizontally. This tray is placed under the collection tray, where the distribution tray provides a number of downward flow tubes for the liquid and gas to flow downward. (3) Fluid divert (4) the mixing chamber, located between the collection pan and the distribution tray, and (5) the open end guide tube. Which has the first end and the second end Which one end will connect to Funnel for liquid to pass through the collection tray And the second end opens into the mixing chamber And which ends at These two are positioned so that during normal operation Flow of liquid flowing out from These second ends collide. 2. The distributed device according to claim 1, which also includes a path for Cooling fluid distribution By the way, it is mounted above the collection tray. 3. Distribution equipment according to claim 1 or item 2, which also includes a tray.
