Due to the diversity of raw materials and products and the complexity of the production process, tens of thousands of chemical production processes are formed. In the chemical production process, waste gas containing various harmful gases is generated, which needs to be treated before being discharged. The treatment process of harmful gases will greatly damage the filter core of the filter, thereby reducing the efficiency of waste gas treatment.

After the filtering operation is completed, the cover 400 is rotated in the opposite direction to separate it from the filter chamber 100, at this time the annular liquid storage bag body 530 is not extruded under the action of external force, and is reset under the action of its elastic force, and the liquid in the multiple first hydraulic chambers 550 is drawn back at this time, and the folding filter element assembly 500 returns to the initial folded state.

[0023] Example two, refer to Figures 6-8 On the basis of example one, the inside of each of the folding pipe bodies 520 is equipped with a film pressing assembly 600, the film pressing assembly 600 includes movable rods 620 penetrating and slidingly connected in the limiting plate 590, the movable rods 620 are provided in three, one end of the three movable rods 620 is fixed with a linkage plate 610, the other end of the three movable rods 620 is fixed with rubber pressing blocks 630, the side of the linkage plate 610 is connected with the first hydraulic rod 560 through profiled rods 640, the profiled rods 640 are provided in two, the two profiled rods 640 are respectively fixed on both sides of the first hydraulic rod 560, the bottom of the folding pipe body 520 is provided with a penetrating groove 650 for the movement of the profiled rods 640, and the movement of the profiled rods 640 does not form motion interference due to the penetrating groove 650 in the bottom of the folding pipe body 520. The movement of the profiled rods 640 is driven by the movement of the first hydraulic rod 560, the movement of the linkage plate 610 is driven by the movement of the profiled rods 640, at this time the three movable rods 620 move simultaneously, at this time the three rubber pressing blocks 630 will cooperate with the limiting plate 590 to extrude and position the high-pressure-resistant microporous filter membrane inside it, preventing the high-pressure-resistant microporous filter membrane from being separated and misaligned during the filtering process.

[0024] In particular, when the folding filter element assembly 500 is installed in the filter bin 100 and fully unfolded, the movement of the first hydraulic rod 560 will drive the movement of the two profiled rods 640 fixed on both sides. Since the bottom of the folding pipe body 520 is provided with a through slot 650, the movement of the profiled rods 640 will not form a movement interference. With the movement of the two profiled rods 640, the connecting plate 610 fixedly connected with the profiled rods 640 will be driven to move. At this time, the three movable rods 620 fixed on the connecting plate 610 will simultaneously drive the movement of the three rubber pressing blocks 630. At this time, the three rubber pressing blocks 630 will cooperate with the limiting plate 590 to extrude and position the high-pressure resistant microporous filter membrane in the rubber pressing blocks 630, so as to prevent the high-pressure resistant microporous filter membrane from being separated and misaligned during the filtration process.

The other end of the inside of the second hydraulic bin 720 is provided with a hydraulic rod three 730 slidably connected with the side of the arc-shaped plate 580. When the arc-shaped plate 580 is opened, the hydraulic rod three 730 will be extruded. Under the action of the liquid pressure, the hydraulic rod two 740 will drive the lifting plate 710 to rotate and lift, so as to lift the high-pressure resistant microporous filter membrane, thereby facilitating the replacement of the high-pressure resistant microporous filter membrane.

[0026] In particular, when the folding filter element assembly 500 is installed in the filter bin 100 and fully unfolded, the movement of the first hydraulic rod 560 will drive the movement of the two profiled rods 640 fixed on both sides. Since the bottom of the folding pipe body 520 is provided with a through slot 650, the movement of the profiled rods 640 will not form a movement interference. With the movement of the two profiled rods 640, the connecting plate 610 fixedly connected with the profiled rods 640 will be driven to move. At this time, the three movable rods 620 fixed on the connecting plate 610 will simultaneously drive the movement of the three rubber pressing blocks 630. At this time, the three rubber pressing blocks 630 will cooperate with the limiting plate 590 to extrude and position the high-pressure resistant microporous filter membrane in the rubber pressing blocks 630, so as to prevent the high-pressure resistant microporous filter membrane from being separated and misaligned during the filtration process.
