Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a spray tower demister. Background Technology

[0002] Spray towers exist as a type of environmental waste gas treatment equipment. Based on their working principle, they are classified into circulating water spray towers, alkaline spray towers, and acid spray towers. Based on the tower body material, they are classified into fiberglass spray towers, PP spray towers, and stainless steel spray towers.

[0003] A search revealed Chinese Patent Publication No. CN208626918U, which discloses an integrated desulfurization and denitrification device including a wire mesh demister. The device comprises an absorption tower, a flue gas inlet located on the side wall of the absorption tower, and a flue gas outlet located at the top of the absorption tower. Inside the absorption tower, along the flue gas flow direction, are sequentially arranged a tray, a slurry spray layer, a packing layer, a gas cap tray, a water washing spray layer, and a demister layer. The gas cap tray is connected to the inlet of a circulating water pump, and the outlet of the circulating water pump is connected to the water washing spray layer. A wire mesh demister is also installed between the gas cap tray and the water washing spray layer. This novel wire mesh demister can smooth the water flow, reduce aerosol generation, enhance the capture and washing of fine aerosols, and create a flue gas cleaning process with a concentration difference between the water washing layer and the slurry layer, thereby improving the flue gas removal efficiency. The wire mesh demister and the gas cap tray work together in a compact spatial arrangement.

Currently, high-pressure water washing is usually used to rinse the wire mesh; however, the dense structure of the wire mesh can easily create cleaning dead corners, and high-pressure water washing cannot completely remove stubborn dirt, resulting in low cleaning efficiency.

[0021] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a spray tower demister, including a tower body 3. The outer wall of the tower body 3 is provided with an air inlet pipe 1 and a spray pipe 2. The top of the tower body 3 is provided with an air outlet pipe 4. The inner wall of the tower body 3 is rotatably connected to a rotating mechanism 8. A moving component 13 is fixedly connected between the side walls on both sides of the rotating mechanism 8. A lifting component 12 is provided on the upper side of the moving component 13. A base plate 11 is fixedly provided at the output end of the lifting component 12. An ultrasonic cleaning device 10 is provided on the lower side of the moving component 13. The output end of the ultrasonic cleaning device 10 is fixedly provided on the lower side of the base plate 11. A wire mesh demisting bracket 6 is fixedly connected to the inner wall of the tower body 3. Multiple wire mesh demisting modules 7 are evenly arranged inside the wire mesh demisting bracket 6. The lower side of the wire mesh demisting module 7 is attached to the upper side of the base plate 11. An intelligent water cannon 5 is provided inside the tower body 3. The intelligent water cannon 5 is located above the wire mesh demisting bracket 6.

[0023] Specifically, the ultrasonic cleaning device 10 has sealing, heat dissipation and rust prevention treatments during operation. The wire mesh defogging module 7 is cylindrical in shape. The wire mesh defogging bracket 6 has through holes for installing the wire mesh defogging module 7. The intelligent water cannon 5 can use a PSKD series electric fire water cannon. When using this spray tower, high-temperature flue gas is input through the air inlet pipe 1 and atomized liquid is input through the spray pipe 2. The liquid acts on the high-temperature flue gas to purify it. The purified flue gas moves upward and is defogging and purified by the wire mesh defogging module 7. Then it is discharged through the air outlet pipe 4 or enters the next process.

[0024] When the wire mesh defogging module 7 needs cleaning, the rotating mechanism 8 and the tower body 3 are horizontally rotated together, and the moving component 13 and the rotating mechanism 8 are fixedly connected, causing the rotating mechanism 8 to rotate. The moving component 13 moves linearly horizontally, adjusting the position of the lifting component 12 on the moving component 13 so that the base plate 11 is directly below a wire mesh defogging module 7. Driven by the lifting component 12, the base plate 11 moves upward and slides into the through hole on the wire mesh defogging bracket 6. At this time, a sealing ring is provided on the outer side of the base plate 11 to achieve a seal between the base plate 11 and the through hole on the wire mesh defogging bracket 6; or the base plate 11 moves upward and fits against the lower side of the wire mesh defogging bracket 6, covering the through hole. At this time, a sealing ring is provided on the upper side of the base plate 11 to achieve a seal between the base plate 11 and the lower side of the wire mesh defogging bracket 6.

[0025] By aiming the intelligent water cannon 5 at the wire mesh defogging module 7 sealed by the base plate 11 and covering it with liquid, the ultrasonic cleaning device 10 drives the output end to vibrate the base plate 11 at high frequency. Through the conduction of the liquid, it can perform ultrasonic cleaning on the wire mesh defogging module 7. Repeat the above steps to clean multiple wire mesh defogging modules 7 on the wire mesh defogging bracket 6 in sequence. This not only improves the cleaning efficiency of the wire mesh defogging module 7, but also realizes the function of cleaning the spray tower without stopping the machine. This solves the problem that the dense structure of the wire mesh is prone to forming cleaning dead corners, and that high-pressure water rinsing cannot completely remove stubborn dirt, resulting in low cleaning efficiency.

[0026] Reference Figure 2 and Figure 4 The rotating mechanism 8 includes a drive assembly 81. An annular groove is provided on the inner wall of the tower body 3. The drive assembly 81 is disposed on the inner wall of the annular groove of the tower body 3. A rotating assembly 80 is provided at the output end of the drive assembly 81. The lower side of the rotating assembly 80 is rotatably connected to the inner wall of the annular groove of the tower body 3. The two ends of the moving assembly 13 are respectively fixedly connected to the side wall between the two sides of the drive assembly 81.

[0027] Specifically, the tower body 3 provides support for the rotating component 80 and the drive component 81. The drive component 81 drives the rotating component 80 to rotate, thereby realizing the function of relative rotation between the tower body 3 and the rotating mechanism 8.

[0028] Reference Figure 2 , Figure 3 and Figure 4 The drive assembly 81 includes a motor 810, which is disposed on the inner wall of the annular groove of the tower body 3. A gear 811 is fixedly disposed at the output end of the motor 810, and the tooth end of the gear 811 is meshed with one side of the rotating assembly 80.

[0029] Specifically, the motor 810 is sealed, heat dissipated and corrosion protected during operation. The tower body 3 provides support for the motor 810. The output of the motor 810 drives the gear 811 to rotate, which in turn drives the rotating component 80 to rotate, thus realizing the function of the drive component 81 driving the rotating component 80 to rotate.

[0030] Reference Figure 2 Figure 3 and Figure 4 The rotating component 80 includes a rotating ring 800, with a plurality of universal balls 802 evenly arranged on the lower side of the rotating ring 800. The lower side of the universal balls 802 is arranged on the inner wall of the annular groove of the tower body 3. A gear 801 is arranged on the outer side of the rotating ring 800. The tooth ends of the gear 801 and the tooth ends of the gear 811 are meshed and connected. The two ends of the moving component 13 are respectively fixedly connected to the side wall between the two sides of the rotating ring 800.

[0031] Specifically, the universal ball bearing 802 allows the rotating ring 800 to rotate on the inner wall of the annular groove of the tower body 3. Through the meshing connection of gear 2 811 and gear 1 801, the rotation of gear 2 811 can drive gear 1 801 to rotate, which in turn drives the rotating ring 800 to rotate, thus realizing the function of relative rotation between the tower body 3 and the rotating ring 800.

[0032] Reference Figure 3 , Figure 4 and Figure 5 The moving component 13 includes a lead screw 131. The bearing seats at both ends of the lead screw 131 are fixedly connected to the side walls between the two sides of the rotating ring 800. A second motor 130 is provided on the outer wall of the lead screw 131. The upper side of the second motor 130 is provided on the lower side of the lifting component 12, and the lower side of the second motor 130 is provided on the upper side of the ultrasonic cleaning device 10. Guide rods 132 are fixedly connected to both ends of the lead screw 131. The outer wall of the guide rods 132 passes through both sides of the second motor 130.

[0033] Specifically, motor 130 is a through-type lead screw motor, and it has sealing, heat dissipation and anti-rust treatment during operation. Driven by motor 130, it moves linearly horizontally on lead screw 131, and the guide rod 132 improves the stability of motor 130's movement. In turn, it can drive lifting assembly 12 and ultrasonic cleaning device 10 to move linearly horizontally. Combined with the rotation of rotating ring 800, it realizes the function of lifting assembly 12 being able to adjust to any position in the horizontal direction.

[0034] Reference Figure 2 and Figure 3 The inner wall of the tower body 3 is provided with a baffle plate 9, which is located below the ultrasonic cleaning device 10.

[0035] Specifically, the design of the baffle plate 9 can guide the high-temperature flue gas and the sprayed liquid to make full contact, thereby improving the separation efficiency.

[0036] Reference Figure 3 The lifting assembly 12 includes a cylinder 14, the lower side of which is located above the motor 130, and the upper side of which is located below the base plate 11.

[0037] Specifically, the cylinder 14 is sealed, heat dissipated and rust-proofed during operation. Driven by the output end of the cylinder 14, the base plate 11 moves up and down, thereby realizing the lifting function of the lifting assembly 12.

[0038] Reference Figure 5 In this embodiment, another structure is provided in the above embodiment: the lifting assembly 12 includes an electric push rod 15, the lower side of the electric push rod 15 is disposed on the upper side of the motor 130, and the upper side of the electric push rod 15 is disposed on the lower side of the base plate 11.

[0039] Specifically, the electric push rod 15 is sealed, heat dissipated and rust-proofed during operation. Driven by the output end of the electric push rod 15, the base plate 11 moves up and down, thereby realizing the lifting function of the lifting component 12.

[0040] Working principle: When the wire mesh defogging module 7 needs cleaning, the output of motor 1 810 drives gear 2 811 to rotate, causing gear 1 801 to rotate. Through the cooperation of universal ball bearing 802, the rotating ring 800 rotates. Driven by motor 2 130, it moves linearly horizontally on lead screw 131, which in turn drives the lifting assembly 12 and ultrasonic cleaning device 10 to move linearly horizontally. This enables the base plate 11 to be adjusted to any position in the horizontal direction, allowing the base plate 11 to be moved directly under any wire mesh defogging module 7.

[0041] If the lifting assembly 12 is a cylinder 14, the base plate 11 is driven to rise by the output of the cylinder 14. If the lifting assembly 12 is an electric push rod 15, the base plate 11 is driven to rise by the output of the electric push rod 15. Through the cooperation of the base plate 11 and the wire mesh defogging bracket 6, the area where the wire mesh defogging module 7 is located forms a bucket-shaped area that can store water. The intelligent water cannon 5 is aimed at the wire mesh defogging module 7 on the upper side of the base plate 11 and covers it with liquid. Driven by the ultrasonic cleaning device 10, its output vibrates the base plate 11 at high frequency. Through the conduction of the liquid, the wire mesh defogging module 7 can be ultrasonically cleaned. Repeat the above steps to clean multiple wire mesh defogging modules 7 on the wire mesh defogging bracket 6 in sequence. In this way, the cleaning efficiency of the wire mesh defogging module 7 is improved, and the function of cleaning the spray tower without stopping is also realized. This solves the problem that the dense structure of the wire mesh is prone to forming cleaning dead corners, and high-pressure water washing cannot completely remove stubborn dirt, resulting in low cleaning efficiency.
