Embodiment 1

[0021] like figure 1 and figure 2 As shown, a pipeline-embedded gas-liquid separation structure for a fuel tank and a fuel tank according to the present invention include an impeller unit 100, and the impeller unit 100 is arranged with a vertical partition with an upper and lower arc-shaped end surface and the inner wall of the exhaust pipe 300. plate 110, a horizontal partition 120 is arranged on one side of the vertical partition 110, and the vertical partition 110 intersects with the horizontal partition 120; One side of the vertical partition 110 is extended with two spiral partitions 130, and the spiral partitions 130 are respectively located in the diagonal area formed by the intersection of the vertical partition 110 and the horizontal partition 120; The arc-shaped edge of the spiral partition 130 is attached to the inner wall of the exhaust pipe 300; a plurality of impeller units 100 are combined in a straight line to form a pipe-embedded gas-liquid separation struct...

Embodiment 2

[0023] like figure 2 As shown, the vertical partition 110 and the horizontal partition 120 are vertically intersected, and the intersection point is located on the axis of the exhaust pipe. The exhaust pipe 300 is equally divided into a smooth part and a flow-restricted part, and the flow of the liquid is restrained while ensuring a sufficient clear path.

Embodiment 3

[0025] like figure 1 and 3 As shown, when the plurality of impeller units 100 are combined in a straight line, at least one impeller unit 100 that is not located at the front and rear ends is connected in reverse, so that the fuel vapor must pass under the diaphragm 120 of the impeller unit 100, and the liquid can fall back. to the bottom of the exhaust pipe 300, and the gas passes through the bottom of the diaphragm 120 and then continues to rise and be discharged.

Abstract

The invention provides a pipeline embedded type gas-liquid separation structure for a fuel tank and the fuel tank; the structure comprises impeller units, the impeller unit is provided with a verticalpartition plate with the upper arc-shaped end face and the lower arc-shaped end face attached to the inner wall of a pipeline, a transverse partition plate is arranged on one side of the vertical partition plate, and the vertical partition plate intersects with the transverse partition plate; the left and right arc-shaped end faces of the transverse partition plate are attached to the inner wallof the pipeline; two spiral partition plates extend from one side of the vertical partition plate and are located in diagonal areas formed by intersection of the vertical partition plate and the transverse partition plate respectively. The arc-shaped edge of the spiral partition plate is attached to the inner wall of the pipeline. The multiple impeller units are combined in a linear mode to form apipeline embedded type gas-liquid separation structure. According to the technical scheme, gas and liquid can be effectively separated, liquid fuel is prevented from entering the carbon canister, thestructure is small, and the internal volume of the fuel tank is not occupied when used in cooperation with the exhaust pipeline.

Description

technical field [0001] The invention relates to the field of motor vehicle fuel tanks, in particular to a pipeline-embedded gas-liquid separation structure for the motor vehicle fuel tank and the fuel tank. Background technique [0002] Usually, the fuel tank of a motor vehicle needs to arrange a plurality of valves, and the fuel vapor is discharged from the valves through the pipes. For the consideration of saving fuel and protecting the environment, these vapors will be discharged into the carbon tank through the pipeline, and the inside of the carbon tank is filled with activated carbon with strong adsorption capacity. environmental pollution. [0003] However, the fuel vapor discharged from the above valve not only contains fuel gas, but may also contain some liquid fuel, and the liquid fuel cannot be effectively absorbed and stored by the activated carbon in the carbon tank, so it is necessary to separate the liquid and gas in the fuel vapor and Recycled to prevent li...
