The second backup pad 152 is vertical setting and its both ends along the horizontal direction extend to mounting hole 12 open-ended lower border department respectively, and the tip of second backup pad 152 passes through bolt or screw detachable connection to have a fixed plate 153, and fixed plate 153 fixed connection is in the opening border of mounting hole 12 to can be when doing support and sealed to adjacent first filter plate 23 opposite side border, can also do the tear open and trade support piece 15, thereby can optimize the result of use.
Referring to fig. 2 and 3, a gasket 3 having a frame shape is disposed between the first filter plate 23 and the opening edge of the mounting hole 12, and the contour of the rim of the gasket 3 is adapted to the opening edge of the mounting hole 12 and the contour of the support member 15, such that the rim of the gasket 3 is fitted to the opening edge of the mounting hole 12 and the upper plate surface of the first support plate 151 is predicted, so as to seal the gap between the mounting hole 12 and the first filter plate 23 and the gap between the first support plate 151 and the first filter plate 23. Wherein, the gasket 3 can be made of NAS.
Meanwhile, since a gap is relatively easily generated between the first support plate 151 and the first filter plate 23, a plurality of fastening members 4 for tightly adhering the first support plate 151 to the adjacent two first filter plates 23 are disposed between the adjacent two first filter plates 23.
The fastener 4 includes the gasket 41 that is long strip shape and the fastening bolt 42 that is used for the fastening, the fastening bolt 42 wears to locate first backup pad 151 and gasket 41, gasket 41 is located between the spiral shell head and the nut of fastening bolt 42, and the border of packing ring 3, first backup pad 151 and first filter plate 23 is by the centre gripping between gasket 41 and first backup pad 151, the last face of two adjacent first filter plates 23 is set up respectively at the both ends of gasket 41, so that can make the gasket 41 closely laminate packing ring 3, first backup pad 151 in two adjacent first filter plates 23 simultaneously through fastening bolt 42.
In addition, in order to facilitate the assembly and disassembly of the first filter plate 23, the nuts of the fastening bolts 42 are fixedly connected to the lower plate surface of the first support plate 151, so that when the first filter plate 23 is assembled and disassembled, only the screws of the fastening bolts 42 need to be rotated; meanwhile, a plurality of fastening bolts 42 are also arranged at the edge of the opening of the mounting hole 12 where the first filter plate 23 is laid, and nuts of the fastening bolts 42 arranged at the edge of the mounting hole 12 are also fixedly connected to the lower plate surface at the edge of the opening of the mounting hole 12, so that the first filter plate 23 can be detached integrally.
The implementation principle of a tray for a nitrogen scrubber in the embodiment of the application is as follows: when in use, the openings 11 on the adjacent tower plates 1 are respectively positioned at two vertical sides, the lower edge of the second overflow plate 14 is partially overlapped with the first overflow plate 13 on the tower plate 1 below the second overflow plate 14, and the lower edge of the second overflow plate 14 is positioned at one side of the first overflow plate 13 below the second overflow plate, which is far away from the filter plate 2; therefore, when the washing water flows into the lower tower plate 1 from the opening 11, the washing water can be primarily buffered and blocked by the first overflow plate 13 and overflows into the cofferdam through the upper edge of the first overflow plate 13, and the filtered H at the moment2The gas overflow pipe 21 is communicated into the cofferdam, and H2 can be relatively fully mixed into the washing water to absorb impurities such as CO and the like due to the action of the bubble cap 22 and the fact that the upper opening edge of the gas overflow pipe 21 is lower than the upper edge of the first overflow plate 13. When the filter plate 2 needs to be disassembled and replaced, the fastening bolts 42 connected with the first filter plate 23 needing to be replaced are only required to be disassembled, the whole filter plate is not required to be disassembled, and meanwhile, when the filter plate 2 needs to be disassembled and replaced, the nitrogen washing tower is taken out only by disassembling the different first filter plates 23 once, so that the possibility of interference caused by the fact that the filter plate 2 is too large is reduced, and the disassembly and replacement are relatively convenient.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
