APPARATUS FOR AND A METHOD OF REMOVING MATERIAL

摘要

Material in liquid or solid form is removed from a surface by means of an open ended ejector pipe which receives a flow of gas under pressure through one or more injectors located along its lenght. In use of the apparatus, a flow of gas is induced into the open end of the ejector pipe sufficient to draw particles of material through the pipe and to eject these particles at a location remote from the free surface of the material.
