Abstract

Official abstract text for this publication.

A gravitational settling tank including a pressure vessel which precipitates solid content contained in slurry in which coal and solvent are blended, and separates the solid-content concentrated liquid from the supernatant liquid, and a supply pipe which supplies the pressure vessel with the slurry. A main body part and a nozzle part which is connected on the downstream side of the main body part and extends horizontally are provided in the supply pipe. A plurality of holes are provided in the nozzle part. By virtue of this, agitation of the solid-content concentrated liquid which has settled in the bottom is inhibited.

First claim

Opening claim text (preview).

The invention claimed is: 1. A gravitational settling tank comprising a pressure vessel configured to separate a slurry in which coal and a solvent are mixed together into a solid-content concentrated liquid and a supernatant liquid by settling solid matter contained in the slurry; and a supply pipe configured to supply the pressure vessel with the slurry, wherein the supply pipe includes a main body part and a nozzle part connected on the downstream side of the main body part, th…
