The cooling method of a condensation bucket has important influence to the distillation process, the domestic sponge titanium enterprise who uses the type of falling U stove at present, the condensation bucket structure that uses is the formula cooling method of soaking, the condensation bucket lower part is intake, set up three delivery port at the different height in condensation bucket upper portion, the reactor latter half is whole to be soaked in the aquatic of a condensation bucket during the distillation, goes out water through the delivery port from different heights and adjusts the inside temperature of cold junction reactor.

The steam volume that the distillation initial stage entered into cold junction reactor inside is great, and the cold junction internal temperature is higher, and the condensation is a bucket and need set up high water level and prevent that the reactor internal temperature is too high to this avoids magnesium vapour to come too late the condensation and enters into vacuum system, and in the distilled middle and later stages of high constant temperature, the steam volume is less, needs the condensation to prop up the bucket and set up relatively lower water level, prevents that the cold junction internal temperature from crossing low and leading to steam to cover the condensation greatly at the cold junction and cause the distillation stifled pipe. The structure of present condensation bucket can't carry out linear regulation, can only carry out three grades of water level control temperature, consequently to the required cooling effect adaptability of different distillation stages relatively poor, and soak formula cooling water inlet and delivery port overall arrangement in 180 positions, the use cooling water is whole to flow below the liquid level, the condition of local water short circuit can not be avoided to exist, and then leads to the uneven phenomenon of cooling.
