The aforementioned scheme solves the problem in the prior art that condensed water mixed with dust is output from the pipe at the bottom of the dust removal bin 101, but the bottom of the dust removal bin 101 is horizontal, and the dust in the condensed water will gradually accumulate at the bottom of the dust removal bin 101, which may subsequently clog the pipe and affect the recovery and recycling of the condensed water. It can be understood that the aforementioned scheme can use the cleaning component to clean the dust in the hydrogen with the sprayed condensed water, thereby preventing the dust from gradually accumulating at the bottom of the dust removal bin 101 and affecting the recovery and recycling of the condensed water.

However, the bottom of the dust removal bin 101 is horizontal and dust is easily accumulated, so the moving driving component is started to drive the limiting moving component to move in the dust removal bin 101 toward the discharge pipe 104, and the limiting moving component drives the lifting gas rod 107 and the scraper 106 to move. The dust at the bottom of the inner cavity of the dust removal bin 101 is scraped toward the exhaust pipe 104 for output, so as to clean the dust removal bin 101. When the scraper 106 moves back and forth, the scraper 106 is driven to move upward by the contraction of the lifting gas rod 107.
