The invention provides an oil gas filtering system, which relates to the technical field of oil gas treatment equipment and specifically comprises a medium filter and a hydraulic mechanism, the medium filter comprises a main body, a filter material and a pressing plate; the liquid inlet, the oil outlet, the air outlet and the water outlet are communicated with the filtering chamber, the liquid inlet is formed in the top of the main body, and the oil outlet and the water outlet are formed in the bottom of the main body; the filter material is arranged in the filter chamber, is an oil-absorbing hydrophobic filter material and is of a soft porous sponge structure; the pressing plate is arranged in the main body and is positioned in the filtering chamber; the hydraulic mechanism is in transmission connection with the pressing plate to drive the pressing plate to move towards the filter material to extrude the filter material. The oil-absorbing and water-filtering filter material in the embodiment can selectively absorb oil-containing wastewater, so that waste oil is absorbed in the filter material, the wastewater can be discharged through the water outlet after passing through the filter material, waste gas can be discharged out of the main body through the gas outlet, and after oil absorption reaches saturation, oil can be discharged in a manner of extruding the filter material through the pressing plate; therefore, stable emission of oil, water and gas is realized.

The application discloses a kind of fibrous felt that can be all-weather fast recovery high viscosity crude oil, preparation method and its application.The fibrous felt includes the fibrous substrate formed by profiled cross-section fiber, and the binder layer, functional layer and hydrophobic coating sequentially loaded on its surface;Functional layer is used to generate Joule heat when energized and generate photo-thermal effect under light;The water contact angle of fibrous felt is greater than 140°.The application also provides its preparation method and application.The application integrates photo-thermal and Joule heat effect in the same felt, realizes all-weather operation ability;Use C-shaped or Y-shaped profiled cross-section fiber, accelerate the penetration and absorption of high viscosity crude oil;Through the synergistic effect of polypyrrole layer and MXene layer, the resistance is significantly reduced and the oil absorption time is shortened.The fibrous felt of the application has simple preparation process, and is suitable for all-weather oil spill recovery in complex environment such as ocean oil spill.

The invention relates to a preparation method of a graphene-carbon nanotube hybrid oil absorption material. The preparation method comprises the following steps: S1, preparing graphene oxide foam; s2, preparing modified graphene oxide foam from the graphene oxide foam; s3, preparing a graphene-carbon nanotube hybrid foam material: heating the prepared modified graphene oxide foam in a tubular furnace, introducing argon into the tubular furnace, introducing hydrogen into the tubular furnace, introducing a catalyst into the tubular furnace through an injection pump, introducing acetylene into the tubular furnace, closing an acetylene channel and the injection pump, and carrying out heat preservation for 2-3 hours at the same time, so as to obtain the graphene-carbon nanotube hybrid foam material. Meanwhile, closing a temperature control system of the tubular furnace, cooling to room temperature, and taking out a sample, so as to obtain the graphene-carbon nanotube hybrid foam material. S4, grafting octadecylamine: preparing an octadecylamine grafting preparation solution, immersing the prepared graphene-carbon nanotube hybrid foam material into the octadecylamine grafting preparation solution, and performing freeze drying to obtain the graphene-carbon nanotube hybrid oil absorption material grafted with octadecylamine.

This utility model discloses an atomizer and an electronic cigarette using the same. The atomizer includes an oil storage body and an atomizing body. The oil storage body has an oil storage chamber and a receiving chamber that are isolated from each other. The atomizing body is located in the receiving chamber. An oil guide hole is provided on the corresponding chamber wall of the receiving chamber for guiding the e-liquid from the oil storage chamber into the receiving chamber. The atomizing body has an atomizing channel, within which are arranged an electric heating element, an oil-absorbing element wrapped around the electric heating element, and an oil guide element made of a material with good adsorption and permeability wrapped around the oil-absorbing element. An oil inlet hole corresponding to the oil guide element is provided on the atomizing body. This utility model, by adopting the above technical solution, solves the problem that existing electronic cigarette atomizers have multiple layers of oil-absorbing elements wrapped around the electric heating element. This not only increases the cost of several layers of oil-absorbing elements but also slows down the oil absorption speed. Furthermore, impurities mixed in the e-liquid can deposit on the outer layer of the oil-absorbing element, preventing e-liquid from entering the inner layer and causing the oil-absorbing element to burn.
