Description

Technical Field

[0001] This utility model relates to the field of gas processing equipment, and in particular to a demisting device for water film dust removal. Background Technology

[0002] Water film dust collectors can remove most of the dust and some droplets from the gas, but the outlet flue gas still carries a large amount of fine water mist. This water mist not only wastes water resources but may also carry pollutants and corrode downstream pipes and fans. Therefore, existing technologies often install a dedicated demister after the water film dust collector. Among the demisters, baffle plate demisters are the mainstream choice, which utilize the principles of gas inertial collision, droplet agglomeration, and gravity separation to achieve efficient collection. However, the droplets condensed on the corrugated plate are relatively dispersed, which is not conducive to rapid collection and recovery. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a demisting device for water film dust removal, which facilitates the rapid collection and recovery of most of the liquid droplets condensed on the corrugated plate.

[0004] The technical solution of this utility model is as follows:

[0005] A demisting device for water film dust removal includes a baffle plate demister and a manifold frame. The baffle plate demister includes a support frame and multiple demister modules arranged in a disc shape within the support frame. Each demister module includes multiple equidistantly arranged multi-directional corrugated plates. The manifold frame includes a manifold frame and collection strips within the manifold frame. The manifold frame is located at the bottom of the support frame, and a manifold groove is formed on the top edge of the manifold frame. A drain outlet communicating with the manifold groove is provided at the bottom of the manifold frame. The number of collection strips is the same as the number of multi-directional corrugated plates, and they are aligned with the bottom of the multi-directional corrugated plates. The top of each collection strip has a collection groove communicating with the manifold groove on both sides corresponding to the multi-directional corrugated plates.

[0006] In a further technical solution, the collecting strip includes a support strip and baffles on both sides of the support strip. The middle part of the support strip is provided with a slot for insertion into the bottom side of the multi-folded corrugated plate. The baffles and the support strip are combined to form a collecting groove.

[0007] In a further technical solution, the bottom of the collection tank slopes downward from the middle to both ends.

[0008] In a further technical solution, the slot at the top of the support bar has beveled surfaces on both sides.

[0009] In a further technical solution, a water spraying structure is also included, which includes a water supply pipe and a number of nozzles disposed on the water supply pipe. The water supply pipe is connected to the manifold frame, and the nozzles are arranged toward the multi-folding corrugated plate.

[0010] In a further technical solution, the top edge of the manifold is provided with a connecting post, and the water supply pipe is arranged in a ring shape with its bottom side connected to the connecting post.

[0011] In a further technical solution, the nozzles include multiple groups, each group having a different nozzle angle and being arranged alternately.

[0012] The beneficial effects of this utility model are:

[0013] 1. When the flue gas carrying mist-like droplets passes through the curved channel formed by the multi-fold corrugated plate, the droplets will collide with the multi-fold corrugated plate and stay there. After most of the droplets accumulate to a certain amount, they will flow down along the multi-fold corrugated plate under the action of gravity and flow into the collection tank, so that the dispersed droplets can be quickly concentrated and merged into the confluence tank, and discharged to the designated location through the drain outlet.

[0014] 2. The water supply pipe can be connected to a water source to directly flush the multi-bend corrugated plate. The multi-angle nozzles provide more comprehensive flushing. Some of the water after flushing from top to bottom can also flow down the multi-bend corrugated plate and be collected in the collection tank. Attached Figure Description

[0022] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0023] Example:

[0024] like Figures 1-5 As shown, a demisting device for water film dust removal includes a baffle plate demister and a manifold. The baffle plate demister includes a circular support frame 11 and multiple demister modules arranged in a disc shape within the support frame 11. Each demister module includes multiple equidistant multi-directional corrugated plates 12. Connecting plates 13 can be welded between the multi-directional corrugated plates 12 of the same demister module to stabilize the structure. The multi-directional corrugated plates 12 at the edges of the demister module can be welded to the inner wall of the support frame 11. The manifold includes a circular manifold frame 20 and collecting strips within the manifold frame 20. The support frame 11 can be mounted on top of the manifold frame 20. A collecting groove 21 is provided on the top edge of the manifold frame 20. The bottom of the flow frame 20 is provided with a drain outlet 22 that connects to the confluence channel 21; the number of collection strips is the same as the number of multi-fold waveform plates 12, and they are aligned with the bottom of the multi-fold waveform plates 12; the collection strips include support strips 31 and baffles 32 on both sides of the support strips 31, and the middle of the support strips 31 is provided with slots 33 that can be inserted into the bottom side of the multi-fold waveform plates 12. To facilitate the insertion of the multi-fold waveform plates 12 into the slots 33, the bottom side of the multi-fold waveform plates 12 extends to the outside of the bottom side of the support frame 11; the baffles 32 and the support strips 31 are combined to form a collection channel, which is located on both sides of the bottom of the multi-fold waveform plates 12. The two ends of the collection channel are higher than the confluence channel 21 and are connected to the confluence channel 21.

[0025] The working principle of the above technical solution is as follows:

[0026] Flue gas carrying mist-like droplets passes through the curved channel formed by the multi-fold corrugated plate 12 at a certain speed. As the flue gas flow direction changes continuously in the curved channel, the droplets, due to their much greater inertia than the gas, cannot follow the flow direction. As a result, the droplets collide with the multi-fold corrugated plate 12 and remain there. After most of the droplets accumulate to a certain amount, they flow down the multi-fold corrugated plate 12 under the action of gravity and into the collection tank. This allows the dispersed droplets to quickly concentrate and flow into the confluence tank 21, and then be discharged to the designated location through the drain outlet 22.

[0027] In another embodiment, such as Figure 4-5 As shown, the bottom of the collection tank slopes downward from the middle to both ends; the slot 33 at the top of the support bar 31 has inclined surfaces 34 on both sides.

[0028] The droplets flowing down the multi-folded corrugated plate 12 can easily flow into the collection tank from the inclined surface 34, and the droplets in the collection tank can easily flow into the confluence tank 21 for collection at both ends.

[0029] In another embodiment, such as Figure 1As shown, the device also includes a water spraying structure, which includes a water supply pipe 41 and several nozzles 42 disposed on the water supply pipe 41. The top edge of the manifold 20 is provided with connecting posts 23 in a ring array. The water supply pipe 41 is arranged in a ring and connected to the connecting posts 23 on its bottom side. The nozzles 42 are arranged facing the multi-folding corrugated plate 12. The nozzles 42 may include multiple groups, and each group of nozzles 42 has a different angle and is arranged alternately.

[0030] The water supply pipe 41 can be connected to a water source to directly rinse the multi-bend corrugated plate 12. The multi-angle nozzles 42 rinse more thoroughly. Some of the water after rinsing from top to bottom can also flow down the multi-bend corrugated plate 12 and flow into the collection tank 21 for recycling.

[0031] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
