Description

Technical Field

[0001] This utility model relates to the field of automated machinery, and in particular to a condensation device for silicon purification. Background Technology

[0002] In existing condensation devices, the condenser tube is generally formed by repeatedly bending a single condensation heat exchange pipe. When condensing, silicon powder will adhere to the pipe during the condensation process. Prolonged adhesion will affect the condensation effect. At the same time, a large amount of silicon powder adhering to the pipe will result in a lot of waste, reduce the silicon powder purification and collection rate, and increase production costs. Utility Model Content

[0005] A condensation device for silicon purification includes a first diversion chamber, a second diversion chamber, and a heat exchange condensation pipe. The first diversion chamber is fixedly installed on the upper end face of the second diversion chamber. A first medium chamber and a second medium chamber are respectively provided in the second diversion chamber and the first diversion chamber. The heat exchange condensation pipe includes an outer tube and an inner tube. An inner tube is provided inside the outer tube. The inner tube is a tube with openings at both ends. One end of the inner tube passes through the second medium chamber and connects to the first medium chamber. The opening of the outer tube communicates with the first medium chamber.

[0006] Furthermore, both the first and second medium cavities are provided with partition plates.

[0007] Furthermore, the number of the partition plates is not less than one, and the partition plates divide the first medium cavity and the second medium cavity into not less than two chambers on average.

[0008] Furthermore, the upper end face of the first medium cavity is provided with a medium outlet, and the second medium cavity is provided with a medium inlet. The medium inlet is connected to one of the separated second medium cavities A. The second medium cavity A connected to the medium inlet is connected to a first medium cavity A that is not connected to a medium outlet, and the first medium cavity A is connected to another second medium cavity B that is not connected to a medium inlet. The second medium cavity B is connected to another first medium cavity B, and so on, until the last first medium cavity N is connected to a medium outlet.

[0009] Furthermore, there is a certain medium flow gap between the inner tube body placed at the end of the outer tube body and the inner cavity of the outer tube body, and there is also a medium flow gap between the outer tube body and the inner tube body.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention utilizes a long, narrow condenser tube, on which a scraper plate can be easily mounted for scraping off silicon powder adhering to the condenser tube, facilitating the collection of silicon powder. Attached Figure Description
