The biological hydrogen purification device based on the hydrate method disclosed in the embodiment is disassembled and assembled as follows:
when the installation is performed, firstly deionized water is injected into the first reactor 110, then the first guide rod 113 is clamped into the first guide hole 134, then the cover 130 is made to approach the first reactor 110, after the first reactor 110 is clamped into the first annular groove 132, the control knob 131 is twisted, the opening 1311 is communicated with the first clamping groove 135, at this time, the second rod 1132 is rotated, the second rod 1132 is clamped into the second clamping groove 137, then the control knob 131 is twisted, the opening 1311 is staggered with the second clamping groove 137, and the installation of the first reactor 110 is completed.
Then, cooling water is injected into the second reactor 120, and the second guide rod 122 is engaged into the second guide hole 136. After the second guiding rod 122 is clamped into the second guiding hole 136, the second guiding rod 122 can push the clamping block 181 back to the connecting groove 138, and one end of the clamping block 181 departing from the second guiding rod 122 is clamped into the clamping hole 112 of the first reactor 110.
Then, the second reaction vessel 120 is moved toward the cover 130, and after the second reaction vessel 120 is engaged in the second annular groove 133, the control knob 131 is twisted to communicate the opening 1311 with the second engaging groove 137, and at this time, the fourth rod 1222 is rotated to engage in the second engaging groove 137. And the control knob 131 is turned again to stagger the opening 1311 and the second slot 137, thereby completing the installation of the second reactor 120. At this time, since one end of the latch 181 is located in the latching hole 112 of the first reactor 110 and the other end of the latch 181 is located in the connecting groove 138, the first reactor 110 cannot be separated from the lid 130, even though the control knob 131 rotates to connect the opening 1311 thereof with the first latching groove 135, the first reactor 110 cannot be separated from the lid 130.
When disassembling, the control knob 131 is first twisted to align the opening 1311 with the second slot 137, and then the fourth rod 1222 is rotated to be perpendicular to the axis of the lid 130, so that the second reactor 120 can be separated from the lid 130, thereby facilitating the replacement of the cooling water.
When the second reactor 120 and the second guide rod 122 are not completely separated from the cover 130, the latch 181 is always restricted in the latch hole 112 of the first reactor 110, so that the first reactor 110 is not separated from the cover 130 by mistake.
When the second reactor 120 and the second guide rod 122 are completely separated from the cover 130, the cover 130 and the first reactor 110 may be removed from the second reactor 120, and after the first reactor 110 is moved to a proper position, the cover 130 is separated from the first reactor 110, so that the used deionized water may be poured into a designated container for recycling. After the second reactor 120 and the second guide rod 122 are completely separated from the cover 130, the latch 181 is separated from the range of the latch hole 112 under the action of the elastic member 182, that is, the first reactor 110 and the cover 130 can be separated only by rotating the second guide rod 122 to the vertical state.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
