[0003] Most double-layer demisters have a set of supporting structures inside to complete the stability of the two-layer filter structure. Without the support of the supporting structure, the filter structure is easily affected by external pressure and vibration, which may cause deformation or damage. This will reduce the service life of the demister and increase maintenance and replacement costs.
[0004] At the same time, most of the existing support structures cannot be adjusted, and the filter structure has been deformed.

[0037] The existing single-layer demister has low efficiency, so through design improvement, a filter layer is added on one side to achieve the effect of double-layer filtration. However, it is found that during use, the structure of the internal support will reduce the filter layer close to the outer side of the support as it is used, resulting in unstable internal filtration effect. In order to improve the frequent occurrence of this problem, this application proposes a double-layer fiber bed demister; while achieving the effect of double-layer filtration, the convenience of adjusting the internal support is also improved.
[0038] The present application is mainly composed of an outer mesh cage 1, an inner mesh cage 2 coaxially arranged with the outer mesh cage 1, a liquid-dropping structure arranged at the bottom of the outer mesh cage 1 and the inner mesh cage 2, a connecting piece 4 arranged inside the inner mesh cage 2, a supporting piece 5 connected to the upper side of the connecting piece 4, and a liquid-dropping structure arranged at the bottom of the outer mesh cage 1 and the inner mesh cage 2.
[0039] For reference Figure 1 A fiber bed 3 is provided in each of the outer mesh cage 1 and the inner mesh cage 2. The two fiber beds 3 are provided to achieve a two-layer filtering effect; wherein the fiber bed 3 is made of corrosion-resistant and high-temperature-resistant glass fiber.
[0040] It should be noted that both the inner mesh cage 2 and the outer mesh cage 1 are pipe structures with multiple through holes on the pipe wall, and flanges are installed at the upper ends of the inner mesh cage 2 and the outer mesh cage 1, and an inner hole with the same diameter as the inner mesh cage 2 is opened in the middle of the flange; two ears are fixed on the inner wall of the inner hole along the two ends of the inner hole diameter; the upper side of the ear is flush with the top surface of the flange; thus, the lifting work is completed through the ear.
[0041] For reference Figure 1 The connecting piece 4 is used for straightening the inner mesh cage 2, so as to maintain the long-term working state of the fiber bed 3 on the inner mesh cage 2; wherein the connecting piece 4 comprises a top plate 41 and a sinking shaft 42; the top plate 41 has a diameter consistent with the diameter of the inner mesh cage 2, and is installed on the top of the inner mesh cage 2; the sinking shaft 42 is coaxially installed at the bottom of the top plate 41 with the top plate 41, wherein the outer diameter of the sinking shaft 42 is consistent with the inner diameter of the inner mesh cage 2; thereby, the sinking shaft 42 is pressed against the inner wall of the inner mesh cage 2 to play a certain supporting effect.
[0042] For reference Figure 1 A support member 5 is provided on the connecting member 4, and the outer mesh cage 1 is supported by the support member 5; the support member 5 includes a wing plate 51, a sliding group 52 and a disc 53; wherein the disc 53 is coaxial with the connecting member 4, and the wing plates 51 are arranged on the disc 53 in an annular and equidistant manner, wherein a plurality of slideways corresponding to the wing plates 51 are arranged at corresponding distribution positions of the disc 53, and the wing plates 51 can move linearly along the slideways; if there is slight deformation inside and other misalignment of the connection, the gap between the connections can be reduced by adjusting the wing plates 51, so that each wing plate 51 can be pressed against the inner wall of the outer mesh cage 1 to form a perfect stabilizing effect.
[0043] It should be noted that after adjusting the wing plate 51, the wing plate 51 is installed and fixed on the disc 53 for support by bolts; the existing middle wing plate 51 is generally set in a fixed form, so there will be certain inconveniences in adjustment and slightly irregular structure when placing the disc 53.
[0044] At the same time, considering that liquid will accumulate in the connection gap between the wing plate 51 and the disc 53 after the wing plate 51 moves, due to the connection setting between the bottom of the disc 53 and the connecting piece 4, the accumulated liquid will not flow downward, so the sliding group 52 is set to control the situation where a large amount of liquid accumulates in the gap; at the same time, the sliding group 52 can effectively increase the supporting force of the connection between the wing plate 51 and reduce the situation where deformation is easy to occur.
[0045] Among them, the sliding group 52 includes a slide groove 521, a slide shaft 522 and a slider 523; the slide groove 521 is arranged in the disc 53; the slider 523 is arranged in the slide groove 521, and can make a linear motion along the direction of the slide groove 521, and press against the wing plate 51 during the movement; wherein the width of the slider 523 is the same as the width of the wing plate 51 on the parallel corresponding side; the slide shaft 522 is arranged at the top of one side of the slider 523, and is used to push the slider 523 to make a linear motion; and after the slide shaft 522 moves, it is tightened by bolts to reduce the back and forth motion of the slide shaft 522.
[0046] For reference Figure 1 The liquid-dropping structure includes a blocking plate 6, a downcomer 7 and a liquid-sealing cup 8. The bottoms of the outer mesh cage 1 and the inner mesh cage 2 are located at the same horizontal plane, and the blocking plate 6 is arranged at the bottoms of the outer mesh cage 1 and the inner mesh cage 2; the downcomer 7 is arranged at the bottom of the blocking plate 6; and the liquid-sealing cup 8 is arranged at the bottom of the downcomer 7;
[0047] When demisting begins, fog droplets will appear in the outer mesh cage 1 and the inner mesh cage 2 after being filtered by the fiber beds 3 at two locations, and the fog droplets will fall downward due to their weight; the blocking plate 6 will receive the fog droplets falling from above, and flow into the liquid sealing cup 8 through the downcomer 7 on the blocking plate 6, wherein the downcomer 7 is arranged to connect the inside and outside of the inner mesh cage 2 at the same time; thereby, the fog droplets settled inside the inner mesh cage 2 and the outer mesh cage 1 are collected synchronously.
[0048] In the utility model, the working steps of the device are as follows:
[0049] 1. First, install the connecting member 4 on the top of the inner mesh cage 2, and then install the supporting member 5 on the connecting member 4, and then adjust the wing plates 51 and the sliding group 52 in the supporting member 5 to enable the multiple wing plates 51 to stably support the inner wall of the outer mesh cage 1;
[0050] 2. Secondly, the mist enters the inner fiber bed 3 from the lower end of the inner mesh cage 2, and passes through the fiber bed 3 into the connecting channel between the inner mesh cage 2 and the outer mesh cage 1;
[0051] 3. Then, another part of the mist passes through the fiber bed 3 inside the outer mesh cage 1 from the outside and enters the connecting passage between the outer mesh cage 1 and the inner mesh cage 2;
[0052] 4. Finally, through the fiber beds 3 at two locations, mist droplets are formed in the outer mesh cage 1 and the inner mesh cage 2; they fall into the blocking plate 6, and the collected mist droplets in the outer mesh cage 1 and the inner mesh cage 2 flow into the liquid sealing cup 8 through the downcomer 7 to achieve the purpose of demisting.
[0053] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of protection claimed by the utility model.
