Description

Technical Field

[0001] This invention relates to the field of condenser ball cleaning technology, specifically a ball circulation cleaning device. Background Technology

[0002] Condenser ball cleaning systems are one of the main auxiliary devices for improving the thermal efficiency of steam turbine cycles. Since the 1970s, many thermal power plants in China, regardless of the age or capacity of their units, have widely adopted this system. Ball cleaning is an online, continuous cleaning method that improves condenser heat transfer, reduces turbine back pressure, and increases power generation without requiring shutdown or load reduction, thereby reducing coal consumption and improving operational economy. Furthermore, it reduces copper tube corrosion and extends service life. Especially with increasing unit power, the urgent need for energy conservation, emission reduction, and improved unit economy makes the importance of ball cleaning systems even more prominent.

[0003] The working principle of the ball cleaning system: Using suitable sponge balls, the balls are put into the system through the manhole of the ball loading chamber. The balls are pumped into the cooling water inlet pipe by the ball pump. The balls flow into the condenser water chamber with the water. The diffused balls are evenly distributed into the cooling pipes and squeezed through, carrying away the dirt attached to the inner wall of the pipes and dispersing it into the water flow. The ball collection net on the condenser outlet pipe section recovers the balls in the water flow, which are then pumped out by the ball pump and sent back to the ball loading chamber. This process is repeated.

[0004] In the existing technology, during the cleaning process, the rubber balls can only clean the surface of the rubber balls along the flow of water. However, for dirt that is both adhesive and dissolving, the dirt will adhere to or penetrate into the sponge rubber balls after dissolving or adhering, resulting in incomplete cleaning of the rubber balls.

During transport, the receiving pipe collects the separated, water-saturated sponge balls, which then flow downwards in an inclined pipe. When they reach the extrusion pipe, the arc-shaped protrusion rotates to its upper end, squeezing the sponge balls by the protrusion and the semi-circular ring mesh pipe. This forces out the permeated, dissolved, and adhered dirt, achieving thorough cleaning of the balls. As the extrusion pipe rotates, the arc-shaped protrusion rotates to its lower end, increasing the inner diameter. The balls continue to fall and are transported along the U-shaped pipe to the upper end of the lower filter screen. There, the filtered water flow impacts the balls, causing them to re-absorb water. They then undergo a secondary extrusion cleaning via a lower transfer assembly, improving the tilting quality of the balls. After cleaning, the balls are circulated to the condenser for further cleaning via a ball pump assembly. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 10 The present invention provides a technical solution:

[0035] Example 1: A ball circulation cleaning device, comprising a cleaning tank 1, an inlet 2 at the upper end of the cleaning tank 1, and two sets of vertically parallel filter screens 6 arranged at an angle in the inner cavity of the cleaning tank 1.

[0036] The wastewater from the condenser, along with the rubber balls, is transported to the cleaning tank 1 through the feed inlet 2. The water flow is then filtered by the filter screen 6 to separate the rubber balls from the water flow.

[0037] The filter screen plate 6 is provided with a transfer component 10, which consists of a receiving pipe 18, an extrusion pipe 19 and a U-shaped pipe 20. The receiving pipe 18 is located at the upper end of the filter screen plate 6, and a semi-circular receiving opening 21 is provided on the receiving pipe 18. A guide plate 22 is provided on the outside of the receiving opening 21, which is inclined and fits against the inclined surface of the upper end of the filter screen plate 6.

[0038] The rubber balls impacting the inclined surface of the filter screen plate 6 are transported to the receiving opening 21 by the guide plate 22, and the rubber balls are transported downward along the receiving pipe 18.

[0039] Both the receiving pipe 18 and the U-shaped pipe 20 are provided with semi-circular stepped grooves 29 at their ends. A semi-circular mesh pipe 34 is provided between adjacent semi-circular stepped grooves 29. Both ends of the semi-circular mesh pipe 34 are provided with semi-circular end plates 35 that fit with the stepped surface of the semi-circular stepped groove 29. The semi-circular end plates 35 are provided with multiple sets of mounting holes 36 arranged in a circumferential array. The stepped surface of the semi-circular stepped groove 29 is provided with screw holes 30 that overlap with the mounting holes 36. The semi-circular end plates 35 are fastened to the semi-circular stepped groove 29 by screws that pass through the mounting holes 36 and the screw holes 30. The semi-circular mesh pipe 34 is located at the upper end of the arc-shaped protrusion 33. The outer diameter of the semi-circular mesh pipe 34 is smaller than the minimum inner diameter of the arc-shaped protrusion 33. The arc-shaped inner wall of the semi-circular mesh pipe 34 fits with the inner wall of the receiving pipe 18 and the U-shaped pipe 20.

[0040] By setting the semi-circular end plate 35 and the semi-circular stepped groove 29 to cooperate, the semi-circular mesh tube 34 is installed through the extruded tube 19.

[0041] The drive assembly includes a drive gear 9. A support 8 is vertically installed on the inner wall of the cleaning tank 1. The drive gear 9 driven by a motor is installed on the support 8. The drive gear 9 meshes with a gear ring 24. The other end of the receiving pipe 18 extends downward at an angle and connects to the extrusion pipe 19. The extrusion pipe 19 is eccentrically positioned with the receiving pipe 18. The extrusion pipe 19 is located at the lower end of the receiving pipe 18. A gear ring 24 is installed on the outer wall of the extrusion pipe 19. A U-shaped arc protrusion 33 is installed at the lower end of the arc inner wall of the extrusion pipe 19. The thickness of the middle of the arc protrusion 33 is greater than the thickness on both sides. The two sides of the arc protrusion 33 are smoothly attached to the arc inner wall of the extrusion pipe 19.

[0042] The drive gear 9 drives the gear ring 24 to rotate, thereby realizing the rotation of the extrusion tube 19. During the rotation of the extrusion tube 19, the arc-shaped protrusion 33 rotates up and down. When the arc-shaped protrusion 33 rotates to the upper end (e.g. Figure 10 As shown), the sponge ball is squeezed by the arc-shaped protrusion 33 and the semi-circular ring tube 34, causing the penetrating, dissolved, and adhered dirt water to be squeezed out, achieving the purpose of thoroughly cleaning the sponge ball. As the squeezing tube 19 rotates, when the arc-shaped protrusion 33 rotates to the lower end (as shown), Figure 9 As shown in the diagram, the inner diameter increases, and the rubber ball continues to fall.

[0043] The other end of the extrusion tube 19 is connected to a U-shaped tube 20. The extrusion tube 19 is rotatably installed between the receiving tube 18 and the U-shaped tube 20. One end of the U-shaped tube 20 is located at the upper end of the filter screen plate 6. The middle bent section of the U-shaped tube 20 is fixed to the inner wall of the cleaning tank 1. The other end of the U-shaped tube 20 extends to the lower end of the filter screen plate 6, and the lower end port of the U-shaped tube 20 is directly facing the upper end face of the lower filter screen plate 6. The transport assembly includes a transfer box 4 and a ball pump assembly. One end of the transfer box 4 is connected to the lower inner cavity of the cleaning tank 1, and the other end of the transfer box 4 is connected to the ball pump assembly.

[0044] The rubber balls are transported along the U-shaped tube 20 to the upper end of the lower filter screen plate 6. With the impact of the filtered water flow, they are filled with water again and are cleaned by secondary squeezing through the lower transfer component 10, thereby improving the tilting quality of the rubber balls. After cleaning, the rubber balls are transported back to the condenser for circulation cleaning through the transfer box 4 and the rubber ball pump assembly.

[0045] Example 2: Based on Example 1, the feed inlet 2 is inclined and the lower end of the feed inlet 2 is directly opposite the upper filter screen plate 6. The upper side frame 7 and the lower side frame 11 are staggered on both sides of the inner wall of the cleaning tank 1. The two ends of the filter screen plate 6 are respectively screwed onto the upper side frame 7 and the lower side frame 11. The lower end of the cleaning tank 1 is provided with a downward inclined guide groove.

[0046] By setting an inclined feed inlet 2, the water flow and the rubber balls directly impact the filter screen 6, thereby improving the filtration efficiency.

[0047] A transfer box 4 and a recovery water tank 3 are provided between the cleaning tank 1 and the rubber ball pump assembly. One side of the transfer box 4 is connected to the guide channel through an inclined connecting pipe 5. The upper ends of the front and rear side walls of the transfer box 4 are provided with linearly arranged multi-component diversion ports, and diversion pipes 12 connected to the recovery water tank 3 are provided on the diversion ports.

[0048] By setting up the diversion pipe 12, the liquid level in the transfer tank 4 is maintained, and the excess water flow is recovered using the recovery water tank 3.

[0049] The ball pump assembly includes a motor 13, a rotating shaft 14, and an impeller 16. The output end of the motor 13 is connected to the rotating shaft 14, and the impeller 16 is sleeved at the front end of the rotating shaft 14. A feed horn pipe 17 is provided between the ball pump assembly and the intermediate transfer box 4. One end of the feed horn pipe 17 is directly opposite the impeller 16, and the other end of the feed horn pipe 17 is connected to the inner cavity of the intermediate transfer box 4. The flow divider is located at the upper end of the rotating shaft 14, and a ball outlet 15 is provided at the upper end of the impeller 16.

[0050] By setting the diversion pipe 12, the liquid level in the transfer box 4 is always kept in the feed horn pipe 17, so that the rubber balls remain facing the feed horn pipe 17 during the floating process, which makes it easy for the rubber balls to be sucked into the rubber ball pump assembly by the rotation of the impeller 16.

[0051] Example 3: Based on Example 2, a lateral protective mesh plate 23 is provided at one end of the receiving opening 21 connected to the flow guide mesh plate 22. The lateral protective mesh plate 23 is vertically installed on the upper end of the flow guide mesh plate 22, and the receiving pipe 18 extends downward at an angle to the rear side of the cleaning tank 1.

[0052] By setting up a lateral protective mesh plate 23, the rubber balls are prevented from falling to the side during the collection process, ensuring that the rubber balls are accurately collected in the receiving pipe 18.

[0053] Both the receiving pipe 18 and the U-shaped pipe 20 are provided with connecting discs 25 at their ends. The connecting discs 25 are provided with annular rotating grooves 26. The cross-section of the rotating grooves 26 is T-shaped. Opening grooves 27 are symmetrically arranged on both sides of the rotating grooves 26. Lateral sliders 32 are installed on the opening grooves 27. Both ends of the extrusion pipe 19 are provided with a pair of rotating blocks 37 arranged in a circumferential array. The rotating blocks 37 are T-shaped structures that rotate and fit against the inner wall of the rotating grooves 26. The rotating blocks 37 are installed in the rotating grooves 26 along the opening grooves 27. The lateral sliders 32 are fixedly sealed on the outer inner wall of the rotating grooves 26. The inner wall of the lateral sliders 32 coincides with the inner wall of the rotating grooves 26.

[0054] By setting the opening slot 27, the rotating block 37 can be conveniently installed on the rotating slot 26, thereby realizing the rotating installation on both sides of the extrusion tube 19.

[0055] An extension frame 28 is provided on the outside of the opening slot 27. A transverse thread is provided on the outside of the extension frame 28 and is rotatably mounted on the screw 31. The end bearing of the screw 31 is rotatably mounted on the side slider 32. The inner diameter of the receiving tube 18 and the U-shaped tube 20 is larger than the outer diameter of the rubber ball. The inner diameter of the extrusion tube 19 is larger than the inner diameter of the receiving tube 18 and the U-shaped tube 20. The minimum distance between the arc-shaped protrusion 33 and the central axis of the receiving tube 18 is smaller than the outer diameter of the rubber ball.

[0056] By setting screw 31, the position of the lateral slider 32 can be easily adjusted. After the rotating block 37 is installed, the lateral slider 32 is driven to block the outer port of the opening slot 27 by the advancement of screw 31, so as to prevent the rotating block 37 from falling off.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
