Abstract

PURPOSE: To eliminate scale sticking on heating surfaces and clogging of the device by using an outside kettle type evaporator separating the evaporator and a heating chamber, and additionally providing a settling chamber below the evaporator.
CONSTITUTION: In refining of, for example, semiconductor high-purity silicon chloride, the liquid-state crude trichlorosilane and silicon tetrachloride obtained by the reaction of metallic silicon and gaseous HCl are pumped as raw liquid through a feed port 5 into an evaporator 1. The solid chlorides such as aluminum chloride, iron chloride, calcium chloride and other in the raw liquid settle into a settling chamber 14 lower than the opening part of a liquid passage 12 down to a heating kettle 10 in the lower part of the vessel 1. Then, the amount of the solid chlorides flowing into the heating chamber of an outside kettle 10 past the passage 12 is much less than that of the raw liquid supplied from 5.
