The invention provides a metal arsenic preparation system. The metal arsenic preparation system comprises a conveyor belt feeding machine, a reduction reaction furnace, a gas-solid separator, a crystallizer and a carbon powder recovery assembly. The conveyor belt feeding machine is used for conveying arsenic trioxide solids; the reduction reaction furnace can effectively carry out reduction reaction on arsenic trioxide solid and carbon powder under a high-temperature condition to generate arsenic gas and carbon dioxide gas. The gas-solid separator enables arsenic gas and carbon dioxide gas generated by the reaction to be efficiently separated from unreacted carbon powder. The crystallizer enables arsenic gas to be fully condensed and crystallized into metal arsenic solids, and a fixed exhaust port and a gas exhaust port in the crystallizer are respectively used for discharging the metal arsenic solids and carbon dioxide gas, so that effective separation and collection of products are realized. Due to the arrangement of the carbon powder recycling assembly, the carbon powder can be recycled again, the resource utilization rate is remarkably increased, the production cost is reduced, and the economical efficiency and sustainability of the whole device are improved.

The application belongs to the technical field of thermosetting resin preparation, and particularly relates to a thermosetting resin capable of being heated and degraded for recycling, a preparation method and application thereof. The structural formula of the thermosetting resin is shown in formula I, II, III and IV. The thermosetting resin capable of being heated and degraded for recycling is prepared by using ester-based alkyne and di-oxime compounds. The thermosetting resin is selectively and quantitatively broken under relatively mild heat treatment conditions by using the thermal reversible characteristics of enoxyl bond, and high-purity original monomers are efficiently depolymerized and recycled. The monomer recovery rate can reach more than 88%, high-value closed-loop recycling is realized, and the resource utilization rate is greatly improved. In the preparation process, no inert gas protection is needed, and no harsh catalyst is needed, which greatly reduces the energy consumption and equipment requirements, and the recycling process is more energy-saving, safe and low in cost. Meanwhile, the alkyne-oxime click reaction has the characteristics of high efficiency, high atom utilization rate, no by-product and mild reaction conditions, which is beneficial to material preparation and recycling.

This invention discloses the application of NaOH-KOH molten salt in the depolymerization of PET plastics, belonging to the field of polyester plastic depolymerization technology. This invention uses NaOH-KOH molten salt as the substrate for PET depolymerization and employs a xenon lamp to simulate sunlight as the heat source for the reactor.
