This invention relates to the field of medical blood purification equipment technology, and discloses a lipid adsorption material regeneration device, including a main body, a rotary switching module, an adsorption column module, a dynamic pressure balancing system, a fluid pipeline system, and a main controller. The rotary switching module drives the adsorption column module to switch between three stations: treatment, regeneration, and balancing preparation. The adsorption column module is filled with pH-responsive hydrogel material to achieve adsorption and regeneration functions. The dynamic pressure balancing system forms a magnetic circuit through a magnetic piston and electromagnetic drive components in a bypass pipe, which senses and adjusts the pressure inside the column in real time. The fluid pipeline system controls the connection of input and output connectors via an electric push rod to achieve fluid switching. The main controller integrates data from multiple sensors, including pressure, pH, and optical sensors, to intelligently terminate the regeneration process. This invention achieves in-situ online regeneration of the adsorption material, continuous uninterrupted treatment, and precise closed-loop control, improving treatment efficiency and safety, and significantly reducing consumable costs.

The application relates to the technical field of explosion suppression agents, in particular to a novel inorganic porous explosion suppression material and a preparation method thereof. The steps comprise the following: placing dried molecular sieves in a metal salt solution with the same volume as the water absorption amount of the molecular sieves, placing the molecular sieves in a constant-temperature oscillator for impregnation, then drying the molecular sieves in a blast drying oven for 12 hours, and then placing the molecular sieves in a muffle furnace for calcination for 5 hours, so that the molecular sieve powder modified by different metal ions is prepared. The prepared inorganic porous explosion suppression material has the advantages of being economic and efficient, low in cost, non-toxic and harmless, and applicable to industrial production, and can be applied to the field of methane explosion suppression.

This invention provides a NiO x A method for preparing a Ni(OH)₂ / NF supported palladium nanoparticle catalyst includes the following steps: Nickel foam (NF) is sequentially placed in hydrochloric acid solution, acetone solution, and deionized water, ultrasonicated, and dried to obtain pretreated NF; Nickel nitrate hexahydrate and hexamethylenetetramine are dissolved in deionized water, ultrasonicated until a homogeneous solution is formed, poured into a high-pressure reactor, and the pretreated NF is vertically immersed into the homogeneous solution, sealed, and subjected to a hydrothermal reaction. After removal, it is washed and dried to obtain a Ni(OH)₂ / NF intermediate with an ultrathin array of nickel hydroxide nanosheets; The obtained Ni(OH)₂ / NF intermediate is placed in a tube furnace and sintered under nitrogen conditions to obtain NiO with a porous array of nickel oxide nanosheets. x / NF precursor. The obtained NiO x The / NF precursor was placed in a palladium salt solution and reacted at a constant temperature. After removal, it was washed and dried to finally obtain NiO. x / NF supported palladium nanoparticle catalyst. This application also discloses a NiO x / NF supported palladium nanoparticle catalyst and its electrocatalytic method for PET plastics.
