The invention discloses a fuel vapor liquefaction recovery device and a fuel vapor discharge system thereof. The fuel vapor liquefaction recovery device comprises an upper end cover, a casing and a lower end cover which are sequentially connected from top to bottom to form a sealed cavity. The upper end cover, the shell The body and the lower end cover are respectively provided with a first pipe joint, a second pipe joint, and a third pipe joint; the housing is provided with an annular self-rotating separation chamber corresponding to the second pipe joint, and the self-rotating separation The inner edge of the chamber surrounds and forms a hollow part that penetrates up and down. The upper end of the hollow part communicates with the first pipe joint. The casing is provided with an impeller assembly and a separation guide cover under the self-rotating separation chamber; inside the lower end cover A one-way valve assembly is provided which only flows in the direction of the third pipe joint. The invention utilizes the kinetic energy formed by the high-speed fuel vapor generated during refueling, through the airflow self-rotation and the centrifugal force separation of the blades, gathers the tiny droplets to liquefy them, and returns them to the fuel tank assembly.

The invention relates to the technical field of a nanometer material and provides a self-cleaning fluidized bed reactor for carbon nanotube production. The self-cleaning fluidized bed reactor comprises a fluidized bed reactor body with a reaction chamber and a rotating device arranged in the reaction chamber, wherein the rotating device comprises a rotating shaft and a rotator; the rotating shaft is longitudinally arranged along the center of the reaction chamber; the rotator is connected with the rotating shaft and is rotated under the driving of the rotating shaft; the reaction chamber is provided with a flow inlet and a flow outlet; the gas flows in through the flow inlet and flows out through the flow outlet; the rotating shaft is communicated with the flow inlet; the rotator is communicated with the rotating shaft; a plurality of gas holes are formed on the rotator; the gas holes are opposite to the inner wall of the reaction chamber and are communicated with the rotating shaft; gas flows out through the gas holes. In the self-cleaning fluidized bed reactor for carbon nanotube production, the rotator is rotated under the driving of the back-flushing acting force of the gas flow; when the rotator is rotated, the catalyst and the carbon nanotube adhered to the inner wall of the reaction chamber are cleaned by the rotator; the inner wall of the reaction chamber is washed by the gas sprayed from the gas holes; the carbon nanotube is prevented from being locally accumulated on the inner wall of the reaction chamber and accordingly causing the reduction of effective volume in the fluidized bed.
