CHEMICAL POURING NOZZLE FOR CRYSTALLIZATION TANK

摘要

PROBLEM TO BE SOLVED: To provide a chemical pouring nozzle for a crystallization tank capable of preventing crystals from being deposited on the liquid chemical pouring nozzle provided on the crystallization tank and smoothly and uniformly performing pouring of the crystallization liquid chemical. SOLUTION: A reverse flow prevention means becoming in the opened state by pouring pressure of the crystallization liquid chemical is provided on a jet port 31 of the chemical pouring nozzle 22 for pouring the crystallization liquid chemical fed from a liquid chemical pouring pipe into a mixture liquid of raw water in the crystallization tank with a crystallization material. The reverse flow prevention means can be formed by attaching a cylindrical elastic member 32 so as to cover the jet port 31. COPYRIGHT: (C)2005,JPO&NCIPI
