Embodiment 1
[0029] The reaction furnace outlet was discharged from the liquid mixture obtained by cold-bonded separation, and the liquid mixture of silicon tetrachloride was required, and it is necessary to pass through a rectification column (referred to as a cold hydrogenated coarse tower) to combine trichloride and tetrachloride. Departure. The impurity content in the isolated trichloride is too high as the requirements of the production of polysilicon, and is required to be sent to the rectification system for multi-stage rectification purification. Due to the multifestine silicon in the top of the coarse column, the cooling medium of air cooling, water cooling or even lower temperature is cooled, and the temperature of the top elimination of trichloride is between 20-50 ° C, and the rectification system first-stage tower The material plate temperature is more than 70-90 ° C, and the feed temperature is obviously low.
[0030] The use of a partial material having a cold hydrogenation furn...
