Abstract
The present disclosure provides a gas-solid separation structure including: a feeding pipeline including a first feeding part, a second feeding part and a first valve disposed between the first and second feeding parts; a discharge pipeline having a first opening and a second opening opposite to each other, the second feeding part extending into the discharge pipeline via the first opening; wherein an exhaust channel is formed between the second feeding part and the discharge pipeline, exhaust holes are formed in a portion of the discharge pipeline opposite to the second feeding part, and the exhaust channel is in communication with the exhaust holes. The present disclosure further provides a feeding device and an electrochemical deposition apparatus. The present disclosure can improve the problem of interference with medicine powder release caused by gases entering the discharge pipeline.
