Description

TECHNICAL FIELD

[0001] The present application relates to the field of methanol hydrogen generator, in particular to a methanol vaporization device for vehicle-mounted methanol hydrogen generator. BACKGROUND

[0002] The vehicle-mounted methanol hydrogen generator generates hydrogen and carbon dioxide by reforming reaction of methanol and water vapor under the action of a catalyst. The generated mixed gas is purified by pressure swing adsorption (PSA) or palladium membrane purification technology to obtain hydrogen with a purity of ≥99.99%, which is directly used as fuel for vehicle fuel cell power generation or driving motor. Among them, the methanol vaporization device is one of the core components, which converts liquid methanol into gaseous methanol for subsequent mixing with water vapor for reforming reaction to produce hydrogen.

Exhaust pipe 106 is installed below the vaporization chamber.

[0032] The process of methanol vaporization is as follows: the methanol in the methanol storage tank is extracted by the pump body therein, transported into the input pipe 4 of the methanol vaporization device, then sprayed out in the form of atomized methanol through the nozzle 11, then the methanol is heated by the heating assembly to form vaporization, and then the vaporized methanol is discharged from the exhaust pipe 106.

[0033] The atomized methanol sprayed out by the nozzle 11 splashes onto the elastic thin cylinder 10, causing the problem of methanol adhering to the elastic thin cylinder 10. The elastic thin cylinder 10 is collided by the impact assembly 5 to make the elastic thin cylinder 10 vibrate, so that the adhered methanol is shaken off.

[0034] The methanol shaken off and the methanol not completely vaporized fall to the bottom of the vaporization chamber and are collected in the liquid collecting cavity 107; the methanol collected in the liquid collecting cavity 107 is sucked by the suction assembly 12 and is returned to the methanol storage tank through the return pipe 6.

[0035] Through the above design, the methanol on the elastic thin cylinder 10 is conveniently discharged downward; at the same time, the methanol not vaporized is conveniently collected, and the return is reused.

[0036] As shown in Figure 3 and Figure 9 , as a specific technical solution, the impact assembly 5 comprises a first fixed cylinder 501; the first fixed cylinder 501 is fixedly connected with the side wall of the top cylinder 2 of the vaporization chamber, a guide ring 504 is fixedly installed in the first fixed cylinder 501, an impact column 502 is slidingly sleeved with the guide ring 504, one end of the impact column 502 located outside the first fixed cylinder 501 faces the elastic thin cylinder 10, a disc body 506 is fixedly installed at one end of the impact column 502 located in the first fixed cylinder 501, the disc body 506 is connected to the first fixed cylinder 501 in a matching manner, a guide hole is formed at one end of the first fixed cylinder 501, a connecting rod 503 is slidingly sleeved with the guide hole, the connecting rod 503 is connected with a driving part 13, one end of the connecting rod 503 is connected with the disc body 506 through a locking part, an unlocking part is arranged on the disc body 506, and the inner wall of the first fixed cylinder 501 is elastically connected with the disc body 506 through a first spring 509.

[0038] Then, the connecting rod 503 is moved to the right to reset, and the locking portion on the connecting rod 503 is locked with the disc body 506 again for next impact.

After locking, the connecting rod 503 moves to the left, which can drive the disc body 506 and the impact column 502 to move to the left.

[0043] When the disc body 506 is separated from the stop ring 505, the movable column 515 and the first plug rod 521 are reset through the third spring 517 and the fourth spring 523.

[0044] In summary, the whole impact assembly 5 only needs to control the connecting rod 503 to move left and right, which is simple and convenient; at the same time, the impact compresses the first spring 509 to store power of the first spring 509 to generate the power of the impact; through the power storage design, the impact vibration effect is guaranteed.
