Abstract: The present invention belongs to the field of environmental materials, and discloses a simulation method for analyzing a diffusion property of a water-soluble monomer in a hydrogel membrane. The method specifically includes the following steps: 1) selecting a hydrogel membrane material and a water-soluble monomer to be simulated; 2) constructing an initial model; 3) optimizing a molecular dynamics model of the hydrogel membrane system; 4) performing a molecular dynamics simulation of the optimized model; 5) drawing a mean square displacement-time (MSD-t) curve; and 6) calculating a diffusion coefficient of a water-soluble monomer molecule in the hydrogel membrane system. The present invention analyzes the diffusion performance of the water-soluble monomer molecule in the hydrogel membrane system on a molecular level.

Abstract: Some embodiments of the disclosure provide systems and methods for a bearingless hydraulic rotary stirring water distributor. According to an embodiment, the bearingless hydraulic rotary stirring water distributor includes a rotary inlet pipe, stirring pipes, water distribution pipes, a ball head shaft, a fixed inlet pipe, a bowl seat, a first seal ring, and a second seal ring. The stirring water distributor is vertically mounted, the fixed inlet pipe is vertically arranged and inserted into the rotary inlet pipe, the fixed inlet pipe and the rotary inlet pipe are mechanically sealed through the seal rings therebetween, the rotary inlet pipe is a vertically mounted pipe, and the rotary inlet pipe is vertically mounted in a semispherical groove of the bowl seat through the ball head shaft mounted at one end of the rotary inlet pipe.
