This invention discloses an electrolytic water anode mesh, its preparation method, and an electrolysis apparatus, relating to the field of hydrogen production through water electrolysis. A collision-embedding method is used to deposit electrolytic nickel powder onto the surface of a preheated nickel mesh. By controlling the deposition conditions, a large-area, stable catalytic working layer with a micro / nano structure can be prepared, enhancing the electrolytic catalytic performance of the electrolysis. Compared to plasma spraying for Raney nickel deposition, the method provided by this invention eliminates the need for subsequent alkaline activation, significantly improving preparation efficiency and reducing equipment, maintenance, and manufacturing costs. Furthermore, it avoids the environmental pollution caused by alkaline aluminum removal activators. Compared to plasma spraying for Raney nickel deposition, the micro / nano dual-scale structure working layer prepared by this invention offers controllable micron and nanoscale dimensions and a three-dimensional structure, further enhancing the electrode's electrolytic catalytic performance and demonstrating excellent application prospects.

The utility model relates to a filter screen structure for ship main engine cooling seawater filtration, including with to install in filter bowl inside's filter screen, the bottom end of filter screen is fixed with axial vertical cylindrical base, the top of filter screen is fixed with with base coaxial cylindrical support seat, the left and right sides of filter screen all are fixed with with to adhere filter bowl inner peripheral wall's side plate, the top of side plate all with support seat's outer peripheral wall linkup fixed, the bottom of side plate all with base's outer peripheral wall linkup fixed. This filter screen structure for ship main engine cooling seawater filtration's filtering effect is better, and the structure is more stable.
