JPS55155702A - Concentrating vessel - Google Patents

Abstract

PURPOSE: The evaporating vessel which comprises mounting a spiral concentrating pipe within the outside barrel provided on the outside circumference of the vessel body, extending the top end thereof to the outside the barrel then inserting the same into the vessel body in the horizontal tangential direction, and which is capable of concentrating the water-contained raw material of high viscosity.

CONSTITUTION: The water-contained material of high viscosity such as organic sludge discharged from the waste-water treating facilities is preheated and is sent through a transport pipe Pb into a concentrating vessel 6, where it is concentrated. First, the water-contained material enters the inside of the preconcentrating pipe 6d in an outside barrel 6c, is fored up in spiral form and is heated by the steam introduced into the outside barrel through steam pipes Pl, 6k. Thence, it is fed into the vessel body 6a through feed-in port 6j and while it is turned by centrifugal force on the outside of a vapor-liquid separating barrel 6e, it is separated of steam. Further, the water-contained material falls down the inside wall surface of the bessel body and is heated by being pressure-contacted with the heating surface of the outside barrel by revolving stirring blades 6s, and therefore it is efficiently concentrated snd is thence extracted through discharge pipes 6i, Pc.
