Description

Technical Field

[0001] This utility model relates to the field of gas-liquid separation technology, and in particular to a load regulating device for a ridge-type demister. Background Technology

[0002] In flue gas desulfurization (FGD) operations, collaboration with users such as peak-shaving power plants and heating stations is often required. This necessitates that the FGD system adapt to significant load variations depending on the user. However, large load variations lead to large changes in the empty tower flow velocity of the FGD tower. These large variations pose a challenge to the demister equipment in the FGD tower, as the FGD demister is a static device and cannot automatically adjust according to the empty tower flow velocity after installation. To maintain a high demister efficiency, the empty tower flow velocity needs to be kept within a relatively small range of variation. Exceeding this flow velocity range results in poor demister performance and can easily lead to excessive emissions. To address this problem, this invention designs a load regulating device for a ridge-type demister, which solves the aforementioned issues. Utility Model Content

[0003] In view of the above technical problems, this utility model provides a roof-type demister load regulating device that adjusts the gas flow rate of the demister body to achieve the best performance of the demister body.

[0004] This utility model provides a load adjustment device for a ridge-type demister, including a ridge-type demister body, characterized in that a flap mechanism is connected inside the lower side of the ridge-type demister body.

[0005] The flapping mechanism includes a driven component, a connecting rod, and a driving component. The left and right sides of the driving component are rotatably connected to the driven component through multiple connecting rods and hinges. The driven component includes a flap A, a driven rotating shaft, and a crank A. The driven rotating shaft is connected to the middle of the flap A. The crank A is fixedly connected to the front and rear positions of the driven rotating shaft. The crank A is located on the same side of the flap A. The driving component includes a crank B, a flap B, a driving rotating shaft, and a positioning plate. The driving rotating shaft is connected to the middle of the flap B. One end of the driving rotating shaft is connected to the positioning plate through a sleeve. The upper and lower sides of the flap B are fixedly connected to the crank B. The crank B located on the upper side of the flap B is opposite to the crank B located on the lower side of the flap B.

[0006] Both flap A and flap B have flap steps at their left and right edges.

[0007] The ridge-type demister body includes a blade assembly, a connecting plate, a side plate, a front plate, a crossbeam, and a rear plate. The left and right sides of the blade assembly are connected to the side plates through connecting plates and lifting lugs, respectively. The two connecting plates are connected to the same crossbeam. The front ends of the two side plates are fixedly connected to the same front plate, and the rear ends of the two side plates are fixedly connected to the same rear plate. The blade assembly is composed of multiple single-hook blades, and the multiple single-hook blades are fixedly connected to form a ridge shape.

[0008] The connecting plate has blade fixing chambers on one side, one above the other, and the two blade fixing chambers are symmetrically arranged. Single hook blades are installed in the blade fixing chambers.

[0009] Multiple mounting holes are provided at the upper end of the side plate, and a sealing strip is provided on one side of the middle end of the side plate.

[0010] The rear end plate has three through holes evenly distributed along its horizontal center side, and each through hole has a sealing strip on its left and right sides.

[0011] Three through holes are evenly distributed along the middle side of the front end plate. A sealing strip is provided on the left and right sides of each through hole.

The limiting plate has limiting holes evenly distributed from 0 degrees to 90 degrees on its surface. Positioning sleeves are provided on the left and right sides of the limiting plate.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a load adjustment device for a ridge-type demister, wherein the air volume is adjusted by controlling the ventilation area through the rotation of each flap around its respective shaft. The drive of the active shaft in the flap mechanism can be manual or automatic (including electric, pneumatic, and hydraulic), enabling the opening or closing of each flap, thereby controlling the cross-sectional area through which gas passes and thus controlling the gas flow rate. By controlling the gas flow rate of the demister within a reasonable range, the demister achieves its optimal performance and meets the ideal requirements for vapor-liquid separation.

[0016] like Figure 1 As shown, this utility model provides a load adjustment device for a ridge-type demister, including a ridge-type demister body, characterized in that a flap mechanism 6 is connected inside the lower side of the ridge-type demister body.

[0017] The flap mechanism 6 includes a driven component 61, a connecting rod 62, and a driving component 63. The left and right sides of the driving component 63 are rotatably connected to the driven component 61 through multiple connecting rods 62 and hinges. The driven component 61 includes a flap A612, a driven shaft 613, and a crank A611. The driven shaft 613 is connected to the middle of the flap A612. The crank A611 is fixedly connected to the front and rear positions of the driven shaft 613, respectively. The crank A611 is located on the flap A61. On the same side of 2, the active component 63 includes a crank B631, a flap B632, an active shaft 633, and a positioning disk 634. The active shaft 633 is connected to the middle of the flap B632. The positioning disk 634 is connected to one end of the active shaft 633 through a sleeve. The crank B631 is fixedly connected to the upper and lower sides of the flap B632 respectively. The crank B631 located on the upper side of the flap B632 is arranged opposite to the crank B631 located on the lower side of the flap B632.

[0018] Flip-plate A612 and flip-plate B632 are both provided with flip-plate steps 635 on their left and right edges.

[0019] The ridge-type demister body includes a blade assembly 1, a connecting plate 2, a side plate 3, a front plate 4, a crossbeam 5, and a rear plate 7. The left and right sides of the blade assembly 1 are connected to the side plate 3 through the connecting plate 2 and the lifting lug 22, respectively. The two connecting plates 2 are connected to the same crossbeam 5. The front ends of the two side plates 3 are fixedly connected to the same front plate 4, and the rear ends of the two side plates 3 are fixedly connected to the same rear plate 7. The blade assembly 1 is composed of multiple single-hook blades 11, and the multiple single-hook blades 11 are fixedly connected to form a ridge shape.

[0020] The connecting plate 2 has blade fixing chambers 21 on one side, one above the other. The two blade fixing chambers 21 are symmetrically arranged, and single hook blades 11 are installed in the blade fixing chambers 21.

[0021] Multiple mounting holes 31 are provided at the upper end of the side plate 3, and a sealing strip 32 is provided on one side of the middle end of the side plate 3.

[0022] Three through holes are evenly distributed on the middle side of the rear end plate 7, and sealing strips 32 are provided on the left and right sides of each through hole.

[0023] Three through holes are evenly distributed on the middle side of the front end plate 4. A sealing strip 32 is provided on the left and right sides of each through hole. The sealing strips 32 are all located on the same side of the front end plate 4. A limiting plate 41 is provided in the middle of the surface of the front end plate 4 on the side opposite to the sealing strip 32. The limiting plate surface has limiting holes 411 evenly distributed from 0 degrees to 90 degrees. Positioning sleeves 42 are provided on the left and right sides of the limiting plate 41. Example 2

[0024] In use, the driven shaft 613 and the driving shaft 633 corresponding to the flap A612 and flap B632 are connected to the corresponding through holes of the front plate 4 and the rear plate 7 through bearings. There are gaps between the flap A612, flap B632 and the front and rear plates and the side plate 3. The front and rear plates are provided with corresponding sealing strips 32 at the closed position of the flaps. The sealing is achieved by the sealing strips 32 engaging with each flap. A flap step 635 is provided at the joint of flap A612 and flap B632. The flap step 635 forms a convex-concave interlocking shape to achieve sealing between the flaps.

[0025] The active rotating shaft 633 of this invention can be driven manually or mechanically, with a rotation range of 0-90 degrees. The 0-degree and 90-degree positions are preferred. When manually driven, such as... Figure 6 , 10 As shown, rotate the handle on the positioning disk 634. After the handle is rotated into position, insert the spring plunger positioning pin into the positioning disk 634 and the limiting hole 411 of the limiting disk 41 to achieve locking and positioning. If it is mechanically driven, no positioning pin is needed, and the position is locked by the driving mechanism.

[0026] The rotation position is determined by the magnitude of the flue gas velocity in the empty tower and the applicable velocity range of the demister body. When the velocity is too low, the flap is closed; when the velocity is too high, the flap is opened. It can be half-open or fully open, with full closure or full opening being preferred. The flap B632 on the active shaft 633 is rotated by an external drive, which in turn causes the crank B631 to move the connecting rod 62 through the hinge. The movement of the connecting rod 62 causes the crank A611 to rotate. The rotation of the crank A611 causes the driven shaft 613 and the flap A612 connected to the driven shaft to rotate, thereby realizing the linkage between the active shaft 613 and the driven shaft 633. It also realizes the simultaneous opening or closing of the flap B632 on the active shaft 633 and the flap A612 on the driven shaft 613, thus controlling the magnitude of the airflow.
