PURPOSE:To enable a large flow rate of gaseous raw materials to feed stably to a reaction vessel by conducting out a pipeline by which the gaseous mixture is fed to the reaction vessel from a bubbler vessel, from the space of the upper part of liquid incorporated in the bubbler vessel. CONSTITUTION:After the gaseous raw material is elevated till the upper end R of a winding tube 9 of the upper part of a condenser, it is descended along the downward winding tube 9 and the constant gas which is directed towards the upper part by means of the two-branched pipe of lower end Q of the winding tube is entered into a pipeline 11, passed through the condenser and communicated to a pipeline 8 in the outlet S of the condenser to be fed to a reaction bessel. The condenser 7 is maintained at constant temp. with the circulating hot water and the gaseous mixture which has been passed through the condenser 7 to the lower part from the upper part is cooled till the temp. of the condenser and the gaseous raw material contained in the gaseous mixture becomes vapor at the temp. of the condenser. In this process, the excess gaseous raw material is condensated in the pipeline incorporated in the condenser and returned into a bubbler vessel 1 along the pipeline. |
