<p><P>PROBLEM TO BE SOLVED: To provide a small-sized solid/fluid contact treatment device which keeps the pressure loss reduced even in the time of treating a large flow rate at a low power cost and prevents the reduction of a reaction rate and the wear of particles. <P>SOLUTION: A plurality of fluid feed pipes provided with a fluid-permeable wall are arranged in a container where solid particles move downward and the contact of the solid particles with the fluid is performed with a small pressure loss by allowing the fluid to pass through the pipe. Further, a plurality of solid particle feed pipes forming a space surrounded with the fluid-permeable wall are arranged in the container where the fluid flows and the contact of the solid particles with the fluid is performed with a small pressure loss by allowing the solid particles to move in the solid particle feed pipes. Furthermore, a plurality of fluid flow passages of which the cross section of the lower part opened is polygonal or semicircular are arranged in the container where the solid particles move downward and the contact of the solid particles with the fluid is performed with a small pressure loss by allowing the fluid to pass through it. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
