The application relates to the technical field of catalysts, and discloses a limited type iodine-based homogeneous immobilized catalyst as well as a preparation method and application thereof. The catalyst comprises a carrier and iodine ions, magnesium ions and quaternary ammonium ions loaded on the carrier, wherein the molar ratio of the magnesium ions, the quaternary ammonium ions, the iodine ions and the carrier is 0.01-1:4-15:1-30:1. The limited type iodine-based homogeneous immobilized catalyst disclosed by the application enhances the electrostatic interaction between iodine ions and quaternary ammonium ions through the molecular sieve limiting effect to construct a limited type structure. The catalyst has significantly enhanced CO2 adsorption and activation capacity, can activate an epoxide compound, and accelerates the ring opening of the epoxide compound. In a cycloaddition reaction catalyzed by the catalyst under the conditions of no solvent and no auxiliary agent, the conversion rate of propylene oxide can reach more than 73%, and the propylene carbonate selectivity can reach more than 85%.

The application discloses a kind of fine particle trapping systems of rotary disturbance combined flue gas condensation, it is related to waste heat recovery and dust removal field, it is characterized in that, including wet limestone-gypsum flue gas desulfurization system, cyclone air device, first stage heat exchanger, rotary fan, second stage heat exchanger and net demister by flue gas pipeline sequentially connected, first stage heat exchanger, second stage heat exchanger are connected with heat pump.The application combines the effect of turbulent flow disturbance and flue gas condensation, on the one hand, through the mode of flue gas condensation, the waste heat and moisture in flue gas are recovered, on the other hand, by adding cyclone equipment, the effective trapping and removal of fine particles are realized.

The application discloses a kind of waste wind power blade supercritical ethanol catalytic depolymerization high-value disposal method.The method comprises the following steps: using co-impregnation method is loaded on γ-Al2O3 Ni and Ru active component, γ-Al2O3, nickel nitrate hexahydrate and ruthenium chloride are dissolved in water and stirred sufficiently, precursor is calcined and activated to obtain Ru-Fe-Ni / γ-Al2O3 Catalyst;Waste wind power blade, catalyst and ethanol are put into batch reactor, sealed, purged with nitrogen, heated to ethanol reaches supercritical state;After reaction, solid phase and liquid phase are separated by suction filtration;Washing, suction filtration solid phase obtains glass fiber and recovered catalyst, glass fiber is combined with fly ash and slag to prepare fiber reinforced concrete brick, realize waste and waste joint resource utilization;Rotary evaporation is carried out on liquid phase to obtain recovered ethanol and high-quality oil, and recovered ethanol and catalyst can continue to be used in reaction kettle.The application can realize high-value and harmless disposal of waste wind power blade, and has good application prospect.

The utility model relates to the technical field of petroleum machinery, in particular to a pipe moving machine, which comprises a connecting frame, hook claw mechanisms, walking mechanisms and sensor assemblies, the claw mechanism is used for hooking an oil pipe or a sucker rod; the walking mechanism is used for moving back and forth along the pipeline; and the sensor assembly is used for speed reduction detection and in-place detection of the pipe moving machine. The traditional oil pipe tripping operation depends on manpower, the labor intensity is high, the physical labor of workers can be reduced by using the pipe moving machine, the labor intensity of the workers is reduced, and the body health of the workers is protected. By using the automatic equipment, the influence of human factors on the operation process can be reduced, so that the accuracy and the consistency of operation are improved, and the production quality is further improved.
