    Abstract: A frustum embedded fabricated composite protective structure is provided, including a restraint frame, a back plate, an infill block and a buffer block. The restraint frame is provided with a plurality of mounting holes matching with the shape of the infill block, the restraint frame is arranged on the back plate, the infill block is in a frustum shape. The buffer block and the infill block are installed in the mounting hole of the restraint frame, the buffer block is arranged on the smaller end of the infill block, and the infill block is wedged into the mounting hole of the restraint frame through a wedge surface mating, . Because this protective structure is assembled by multiple restraint frames and infill blocks, under the prestress restraint of partition blocks, the damage range after penetration or explosion will be significantly reduced, and it can withstand multiple blows.

    Abstract: A three-stage degassing and dewatering device includes a first-stage degasser, a second-stage degasser, an oil drainer, a rod electrode, a dewaterer, and a water drainer. The first-stage degasser implements a first-stage axial-flow type collision buffer degassing and dewatering operation, forming a first-stage crude oil after removing some of the gas and water in the gas-containing and water-containing crude oil. The second-stage degasser implements a second-stage elevated efficient degassing operation, forming a second-stage crude oil after removing the remaining gas in the first-stage crude oil. The rod electrode constructs a dynamic electric field with a high frequency and a high voltage, and implements a third-stage high-frequency and high-voltage rapid dewatering operation together with the dewaterer, forming a qualified crude oil after removing the remaining water in the crude oil emulsion.

    Abstract: The disclosure discloses a catalyst capable of simultaneously removing COS and H2S in garbage gasification and a preparation method thereof, and belongs to the technical field of preparation of desulfurization catalysts. The method includes the following steps: pretreating an SBA-15 molecular sieve with a templating agent unremoved, which primarily includes the steps of removing the templating agent and introducing halogen atoms to modify the molecular sieve; then synthesizing an active component solution; and finally introducing active components into channels of the pretreated molecular sieve via surface tension by adopting an impregnation method, performing washing and drying, and performing calcining under an N2 atmosphere, so as to obtain the catalyst. The catalyst prepared according to the present disclosure can load the active components in fixed positions inside and outside the channels, and the components are easy to obtain, thereby having the advantages of low cost and good desulfurization effects.

    Abstract: A molding process of a co-cured short-fiber resin-based damping composite material and a molding part. Different from a traditional centrifugal processing process of a thin-walled tube of a resin-based composite material, the process uses raw materials including three kinds of materials with different densities and including two kinds of short-fiber epoxy resin with different densities and a damping material. During centrifugal molding, the three kinds of materials are made into fluids to be respectively injected at a uniform speed in three times according to the sizes of the densities. Layering is performed by using different centrifugal forces applied to the three kinds of materials. Co-curing is performed according to a resin curing process after the three kinds of materials are stably distributed, and a tubular thin-walled part of the embedded co-cured short-fiber resin-based damping composite material with a uniform wall thickness is obtained.
