This utility model relates to an anti-clogging reactor for the resource recovery and preparation of ammonium sulfate from high-concentration ammonia-containing waste gas. The reactor body includes an absorption zone and a crystallization zone from top to bottom, with the crystallization zone and the absorption zone connected. The absorption zone is located above the liquid surface, and the crystallization zone is located below the liquid surface. The top of the absorption zone has a tail gas outlet, and the bottom of the crystallization zone has a crystal slurry outlet. An external Venturi reaction zone is located below the absorption zone of the reactor body, connected to the reactor body. The Venturi reaction zone has an inlet for the ammonia-containing waste gas and an inlet for the circulating absorbent liquid. The external Venturi reaction zone forms a primary absorption, reducing the intensity of the absorption reaction within the reactor and significantly improving the anti-clogging capability.

This application relates to the field of polymer materials technology, providing a PET elastomer, composite material, dynamic covalent network polymer, and its preparation method and application. The elastomer is prepared by in-situ self-assembly of crown ether-primary amide dual-functionalized PET through melt blending. Its molecular network integrates a quasi-rotaxane supramolecular crosslinking network. This structure is formed by the host-guest interaction between the crown ether and the primary amide, and can act as a sliding crosslinking point to dissipate energy through the sliding of cyclic components. This application employs a two-step end-capping-in-situ self-assembly process to overcome the technical obstacles of low PET chain-end activity and poor compatibility between polyrotaxane and PET, achieving molecular-level dispersion of quasi-rotaxane in the PET matrix. This fully utilizes the molecular pulley effect to achieve breakthrough toughening of the elastomer. Simultaneously, it combines rigid nanofillers modified with aminosilane coupling agents to form a soft-hard synergistic network, enabling the PET composite material to maintain high toughness while simultaneously improving strength, modulus, and thermal properties.

This invention relates to the field of cleaning device technology, specifically to a milling copper shavings recycling device, including a splash guard, and further comprising: a material guiding section, including two symmetrically arranged material guiding plates disposed below the splash guard, with multiple vibrating units mounted on the material guiding plates; and a cleaning section, including a bearing assembly disposed below the material guiding port of the material guiding plates, with cleaning components mounted on the bearing assembly. The material guiding section reduces the adhesion of untreated copper shavings, and the material guiding plates and vibrating units can gather the copper shavings to the bearing assembly, increasing the distribution density of copper shavings in the bearing assembly and facilitating improved cleaning efficiency of the cleaning components. The cleaning frame in the cleaning components can rub the copper shavings with rollers, which helps to remove impurities from the surface of the copper shavings and improve cleaning quality. In this device, the vibrating units can cooperate with the transmission assembly to make the vibrating plates continuously reciprocate, thereby providing effective vibration force to shake off the copper shavings.

This invention discloses a method for reinforcing and toughening recycled PET using waste rock wool and epoxidized natural rubber, belonging to the field of functional polymers. The invention synthesizes modified rock wool by grafting epoxidized natural rubber onto the surface of waste rock wool fibers, and strengthens the phase interface between the modified rock wool and PET by utilizing the reaction of epoxy residues with recycled PET at a melting temperature, ultimately forming a multiphase, multi-layered structure of rigid rock wool fiber-flexible natural rubber-rigid PET. The resulting composite material exhibits improved impact strength and tensile strength.
