Description

Technical Field

[0001] The invention belongs to the technical field of oil and gas separation and recovery, and in particular relates to a vehicle-mounted oil and gas separation and recovery device. Background Art

[0002] The number of cars in use has increased rapidly, and with it comes an increasing consumption of gasoline. The need to reduce pollution caused by car use is becoming increasingly urgent. Due to the volatile nature of gasoline, the oil and gas escaping from the fuel tank during use, especially during refueling, has increased at an alarming rate every year. Test results show that for every liter of gasoline added to a car, about 1.5 grams of oil and gas will evaporate. With the increasingly stringent control of automobile exhaust, the oil and gas volatilized during refueling has exceeded automobile exhaust, becoming the main source of volatile organic compounds (VOCs).

[0003] In the prior art, a small carbon canister is provided in the on-board automobile fuel system, which is used to absorb the oil and gas emissions caused by heat soak loss and daytime loss of the automobile, and is not used for oil and gas adsorption during the refueling process. Therefore, the existing on-board system cannot recycle the oil and gas during the refueling process, resulting in a waste of resources and environmental pollution. Even if the oil and gas during the refueling process are introduced into the carbon canister in the existing on-board automobile fuel system through an external pipeline, although partial oil and gas separation can be completed, the small carbon canister cannot handle the large amount of oil and gas generated during refueling and the separation is not complete. At the same time, additional devices or methods are also needed to solve the problem of activated carbon regeneration.

[0004] Patent document CN116571023B discloses a pre-oil-gas separation device, comprising an oil-gas separation mechanism, comprising a lubricating oil tank, a first conduit arranged on the lubricating oil tank, and an oil-gas separation component arranged at the end of the first conduit; a collecting mechanism, comprising an air box arranged in the middle of the first conduit, and a collecting component arranged on the air box; a filtering mechanism, comprising a containing component arranged on the air box, a one-way valve arranged on the containing component, and an oil pipe arranged between the one-way valve and the lubricating oil tank, the filter plate is composed of a combination of high-density stainless steel ultra-fine foil strips, which can effectively separate part of the lubricating oil in the air, the setting of the inclined plate is convenient for better limiting the oil residue, and can effectively guide foreign matter in the oil body into the slag discharge pipe, which is convenient for discharging the oil residue, the setting of the slag guide groove can effectively guide the oil residue out, the setting of the motor is convenient for better driving the device, and the second gear is rotatably connected to the filter box through a bearing. Although this patent can pre-process oil and gas, the separation method of this patent is too complicated. The patent uses both gears and belts, which brings the disadvantages of inconvenient maintenance and large floor space. It cannot be applied to automobile on-board systems. At the same time, this patent cannot complete oil and gas recovery. Summary of the invention

[0077] S33, after a preset time, the operation of the variable frequency motor 410 is stopped, the adjustment assembly 300 is returned to the initial state, and the guide plate 710, the lifting shaft 730, the linkage plate 740 and the lifting block 750 are all reset under the action of the spring 720.

[0078] It is not difficult to understand that in the second oil-gas separation process by collision, the oil-gas mixture can collide back and forth between the third through hole 511 , the fourth through hole 512 , the fifth through hole 521 and the sixth through hole 531 .

[0079] Furthermore, during the periodic compression of the sponge board, the variable frequency motor 410 is currently used to run at a low speed, and the holes corresponding to the adjusting screw 310 and the lifting shaft 730 are clearance-matched. When the sponge board is periodically compressed, the guide plate 710 and the adjusting screw 310 do not rotate, and the lifting shaft 730 rotates, so the adjusting screw 310 needs to be replaced regularly. In the case of a larger vehicle model with installation space, two electric push rods can be set on the top of the separation top plate 220, the guide plate 710 is replaced with a piston, and the extended shafts of the two electric push rods are connected to the piston, and the lifting is achieved by the electric push rods, so that the spring 720 does not need to be used.

[0080] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
