[0024] The gas-liquid separation device for coal-to-ethylene glycol provides two technical solutions:

[0025] like Figure 1-3 The first embodiment is shown: comprising a protective tube 1 and a wire mesh demister 4, the protective tube 1 is provided with an air inlet pipe 2, an air outlet pipe 3 and a discharge pipe 7, the air outlet pipe 3 is provided with an installation and disassembly mechanism for installing and disassembling the wire mesh demister 4, and the installation and disassembly mechanism comprises:

[0026] The mounting assembly 5 includes a semicircular groove 51 and an inner semicircular plate 52. The semicircular groove 51 is arranged on the right side of the air outlet pipe 3, and the inner semicircular plate 52 is inserted in the semicircular groove 51. The outer surface of the inner semicircular plate 52 is fixedly connected with an outer semicircular plate 53. The inner surface of the inner semicircular plate 52 is fixedly connected with two upper and lower groups of support plates 54. Each group of support plates 54 is composed of three support plates 54, and the three support plates 54 are fixed on the inner surface of the inner semicircular plate 52 at equal distances. The left side of the outer semicircular plate 53 is fixedly connected with two front and rear mounting blocks 55. The two mounting blocks 55 are both provided with a U-shaped groove 56 on the opposite sides, and a slope 57 is arranged on the left side of the mounting block 55. The left side of the inner semicircular plate 52 is provided with two front and rear sealing assemblies 58.

[0027] The locking assembly 6 is provided with two front and rear groups, which are used to lock the installation assembly 5 after it is installed on the outlet pipe 3. The locking assembly 6 includes a fixing block 61, which is fixedly connected to the front side of the outlet pipe 3. The interior of the fixing block 61 is provided with a mounting groove 62 that matches the mounting block 55. The front side of the fixing block 61 is movably connected with a slide rod 63, which passes through the fixing block 61 and extends to the interior of the mounting groove 62 and is fixedly connected with a cam 64. The surface of the mounting groove 62 between the cam 64 and the inner wall of the mounting groove 62 is sleeved with a return spring 65, and the end of the slide rod 63 located in front of the fixing block 61 is fixedly connected with a handle 66.

[0028] When the wire mesh demister 4 needs to be replaced, the wire mesh demister can be quickly taken out from the air outlet pipe 3 through the installation and disassembly mechanism without removing the pipe connected to the air outlet pipe, which greatly improves the maintenance efficiency.

[0029] like Figure 2 , 3 Figure 4 shows a second embodiment, which mainly differs from the first embodiment in that the sealing assembly 58 includes two front and rear plug-in blocks 581, both of which are fixedly connected to the left side of the inner semicircular plate 52, a sealing sleeve 582 is provided on the outer sleeve of the plug-in block 581, and two left and right fish scale strips 583 are fixedly connected to the front and back sides of the sealing sleeve 582, and the fish scale strips 583 are in the shape of a triangular prism, and two front and rear slots 584 matching with the plug-in block 581 are provided on the left side of the inner wall of the semicircular arc groove 51.

[0031] During installation, the wire mesh demister 4 is placed between the upper and lower support plates 54, and the inner semicircular plate 52 is inserted into the semicircular arc groove 51. At this time, the insert block 581 is inserted into the interior of the slot 584, and the mounting block 55 is inserted into the mounting groove 62. When the mounting block 55 is inserted into the mounting groove 62, the left side of the mounting block 55 contacts the cam 64 and pushes the cam 64 to move, so that the cam 64 can pass over the head of the mounting block 55 and enter the U-shaped groove 56 under the action of the reset spring 65. Then, the cam 64 is rotated so that the longer end of the cam 64 contacts the left side of the inner wall of the U-shaped groove 56, thereby completing the locking.
