Embodiment 1
[0037] Such as figure 1 As shown, the hydrazine propellant waste liquid degradation device provided by the present invention includes a high-voltage electrode 1, a low-voltage electrode 3 and a high-voltage pulse power supply 6;
[0038] The high-voltage pulse power supply 6 is connected to the high-voltage electrode 1;
[0039] The low-voltage electrode 3 is grounded;
[0040] The plasma generated in the gap between the low-voltage electrode 3 and the high-voltage electrode 1 degrades the waste liquid of the hydrazine propellant. In order to adjust the output voltage of the high-voltage pulse power supply 6 conveniently, a transformer 7 is provided, and the transformer 7 is electrically connected with the high-voltage pulse power supply 6 .
[0041] Wherein, the gap between the low-voltage electrode 3 and the high-voltage electrode 1 is 0.5cm˜1.5cm. If the gap exceeds 1.5cm, no plasma will be generated between the high-voltage electrode 1 and the low-voltage electrode 3. I...
Embodiment 2
[0045] This embodiment is a further improvement made on the basis of Embodiment 1, and its structural schematic diagram is shown in figure 2 .
[0046] In Embodiment 2, the same components as those in Embodiment 1 are given the same reference numerals, which will not be repeated here, and only the differences between Embodiment 2 and Embodiment 1 will be described.
[0047] In order to further reduce energy consumption and increase the electric field strength at the gap, an insulating layer 2 is provided outside the high-voltage electrode 1, see figure 2 . The insulating layer 2 is one of insulating materials such as glass, quartz, ceramics, resin, etc. The function of the insulating layer 2 is: on the one hand, it avoids short circuit caused by direct contact between the high-voltage electrode 1 and the waste liquid; on the other hand, the insulating material acts as an insulating layer to improve The electric field strength in the discharge area. The shape of the low-volt...
Embodiment 3
[0049] This embodiment is a further improvement made on the basis of Embodiment 2, and its structural schematic diagram is shown in
[0050] image 3 .
[0051] In Embodiment 3, the same components as those in Embodiment 2 are given the same reference numerals, which will not be repeated here, and only the differences between Embodiment 3 and Embodiment 2 will be described.
[0052] In this implementation, the high-voltage electrode 1, the low-voltage electrode 3 and the insulating layer 2 form a dielectric barrier discharge unit, and there are multiple dielectric barrier discharge units, and a plurality of dielectric barrier discharge units are connected in series to form a dielectric barrier discharge module 4. The dielectric barrier discharge modules 4 are connected in parallel to form a dielectric barrier discharge array 5 . In actual use, one of the dielectric barrier discharge unit, dielectric barrier discharge module 4 and dielectric barrier discharge array 5 can be u...
