2. a kind of methanol according to claim 1 or liquefied ammonia charging device, it is characterised in that: described to fill unit at least
It is two.
3. a kind of using methanol claimed in claims 1-2 or the methods for filling of liquefied ammonia charging device, it is characterised in that: this is filled
Dress method includes the following steps:
Step 1: several fill vehicle rest in it is corresponding fill unit attachment, the first seal cap (9) is mounted on and fills vehicle
Front fill mouth, while the second seal cap (12) being mounted on and fills the rear portion of vehicle and fills mouth；
Step 2: the first stop valve (3), the first ball valve (7), the second stop valve (5) and the second ball valve (10) are opened, fluid reservoir is made
(1) methanol or liquefied ammonia in enter first by liquid pump (2), the first stop valve (3), flowmeter (4) and the second stop valve (5)
In threeway (6), a part of methanol or liquefied ammonia in the first threeway (6) are filled by the first threeway (6), the first ball valve (7), first
Pipeline (8), the first seal cap (9) inlet and fill the front of vehicle and fill mouth and enter and fill in the vehicle tank of vehicle, another part
Methanol or liquefied ammonia fill pipeline (11), the second seal cap by the third end of the first threeway (6), the second ball valve (10), second
(12) inlet and the rear portion for filling vehicle fill mouth and enter in the vehicle tank for filling vehicle；
Step 3: the tail gas filled in the vehicle tank of vehicle passes through the gas outlet of the first seal cap (9) and going out for the second seal cap (12)
Port enters in the second threeway (13), and enters adsorbent equipment (14) by the third end of the second threeway (13) and adsorbed, and takes off
Except pernicious gases such as methanol or liquefied ammonia, treated, and pure air passes through the second shut-off valve (16) discharge atmosphere；
Step 4: two absorbing units, an absorbing unit are in adsorbed state, another absorbing unit is in reproduced state；
Tail gas in step 3 enters in the absorbing unit of adsorbed state, is now in the absorbing unit corresponding first of adsorbed state
Shut-off valve (15) and the second shut-off valve (16) are opened, corresponding first shut-off valve (15) of absorbing unit in reproduced state and
Second shut-off valve (16) is closed；
Step 5: the second stop valve (5), the first ball valve (7) and the second ball valve (10) are in the open state always, arrive when filling vehicle
Behind position, the first seal cap (9) and the second seal cap (12) with it is corresponding fill tight-lipped close connection after, the first stop valve of opening
(3)；
Step 6: it when entirely filling battery limit (BL) there are when security risk, closes the first stop valve (3)；
Step 7: when individually filling vehicle, there are when problem or security risk, closed and there are problems or security risk to fill vehicle phase
Corresponding second stop valve (5)；
Step 8: flowmeter (4) detection flows can close the first ball valve (7) and the second ball valve when flow meets the requirements
(10)；Close the mode that the mode of the first ball valve (7) and the second ball valve (10) combines for automatic, manual, automatic or manual.
