Moisture in the fuel of hydrazine -70 is detected, and the result of purification can be verified, judges the fuel of hydrazine -70 after purification
Whether moisture is up to standard.
Alternatively, the reality on the purification system 1 of the present embodiment is detected to the moisture in the fuel of hydrazine -70 again
Existing mode is to close spray control valve V22, opens detection control valve V23, in the presence of pump 9, the fuel quilt of hydrazine -70 after purification
The moisture content detection device 7 being delivered in the first metaideophone pipeline P31, and then the moisture in the fuel of hydrazine -70 is examined again
Survey, to examine refining effect whether up to standard.Purify it is up to standard after, pump 9 can be stopped and worked, close detection control valve V23.By right
Moisture in the fuel of hydrazine -70 is detected., can be to carrying by being detected again to the moisture in the fuel of hydrazine -70
Pure result is detected again, the fuel of hydrazine -70 after purification can be verified, it is ensured that the quality of fuel of hydrazine -70 is up to standard, enters
And ensure the effect of purification operations.
The method of purification of the present embodiment is after execution of step S03, in addition to step S04：Make the hydrazine -70 in purification tank 3
Fuel flows under gravity to be returned in non-conservation tank 2.
Wherein, the fuel of hydrazine -70 in purification tank 3 is made to flow to return in non-conservation tank 2 under gravity and include：Reduce turnover
The height of tank 2, the fuel of hydrazine -70 in purification tank 3 is flowed under gravity and return in non-conservation tank 2.But this is not limited to, example
Such as, can also be realized by the way of the height of rise purification tank 3.
Specifically, shown in reference picture 6, after non-conservation tank 2 is reduced into original height, the first metaideophone control valve is opened
V14 and gas flow control valve V21, the fuel of hydrazine -70 are flow in non-conservation tank 2 by purification tank 3 through the first metaideophone pipeline P31, week
The nitrogen turned in tank 2 is entered in purification tank 3 by gas flow line P34.After the completion of metaideophone, the first metaideophone control valve is closed
V14 and gas flow control valve V21.So far, the purification processes of the fuel of hydrazine -70 have been completed.
Alternatively, after the completion of step S04, perform the step fuel of hydrazine -70 being recycled into storage tank 0.Specifically, such as
Shown in Fig. 7, the first pressurization control valve V11, first plus/re-injection control valve V13, second plus/re-injection control valve V03, the are opened
Two tail gas control valve V02；Under pressure nitrogen gas effect, the fuel of hydrazine -70 after the purification in non-conservation tank 2 passes through the first conduit successively
21st, plus/re-injection pipeline P21, the second conduit 01 are flow back into storage tank 0, meanwhile, the gas in storage tank 0 is via the second tail gas
Pipeline P02 is discharged in tail gas treatment device, can avoid the tail gas pollution environment of discharge.
