Description

Technical Field

[0001] The utility model relates to the technical field of cleaning, in particular to a novel on-line rubber ball cleaning device. Background Art

[0002] Due to water quality problems in our country, the phenomena of water scale and dirt are very serious. The thickness of water scale and dirt on the inner wall of the condenser cooling pipe is generally about 0.6 - 0.9 mm, and in some areas it is even more serious. At present, the solution to this problem is to conduct an artificial chemical cleaning of the steam turbine condenser regularly, and use a brush to remove the dirt on the inner wall of the copper pipe. This method of artificial chemical cleaning has many drawbacks, such as: it cannot completely remove the dirt, and may damage the inner wall of the copper pipe of the steam turbine condenser due to improper manual operation. More importantly, this method can only temporarily remove the water scale and dirt. With the restart of the steam turbine, new water scale and dirt gradually appear. Generally, after the steam turbine is cleaned manually and then put into use for about 200 hours, the water scale and dirt in the condenser copper pipe will continue to thicken and harden, the heat exchange rate will rapidly decrease, the operating efficiency of the steam turbine will decline, and the energy consumption will continue to increase. Therefore, the steam turbine condenser is mostly in this state for most of the time.

[0003] At present, the rubber ball cleaning device is a relatively good cleaning method for cleaning the condenser cooling pipe. Compared with the mechanical and chemical cleaning methods, it has the advantages of not shutting down the machine, little damage to the cooling pipe, and good cleaning effect. However, due to the system structure of the traditional rubber ball cleaning device, there are problems in use. At present, most of the in-service rubber ball cleaning devices cannot be put into normal use and have poor cleaning effects.

[0004] Two core problems of the traditional rubber ball cleaning device: one is the low ball collection rate. The low ball collection rate is the main problem of the traditional rubber ball cleaning device. Most devices have a ball collection rate of less than 80%, and in the worst case, it is less than 20%. The problem of low ball collection rate makes the traditional rubber ball cleaning device unable to be put into normal use. The other is that it cannot clean all the cooling pipes of the condenser. This problem is the most core problem of the traditional rubber ball cleaning device. Even if the ball collection rate is maintained above 95% for a long time, the traditional rubber ball cleaning device still cannot clean all the cooling pipes of the condenser. The above-mentioned dirt on the condenser cooling pipe and its cleaning situation are very common in domestic power plants, which is a problem that the traditional rubber ball cleaning system cannot completely solve. According to relevant investigations and statistics, among the condenser units equipped with rubber ball cleaning systems in China at present, less than 40% of the rubber ball cleaning systems can be put into normal operation. Among these 40%, less than 38% can achieve a ball collection rate of more than 90%. Therefore, the vast majority of rubber ball cleaning systems are in an abnormal or unusable state, seriously affecting the power generation efficiency of the power plant.

[0005] Specifically, the traditional rubber ball cleaning device mainly has the following problems:

[0006] (1) The number of balls loaded is only 10% of the number of condenser cooling tubes. Because the number of balls loaded is small, the cooling tubes cannot be cleaned comprehensively. According to the characteristics of the circulating water volume in the condenser, the water flow characteristics in the middle are better and the flow velocity is faster. Even if the ball collection rate of the rubber balls can reach the required level, the cleaning is concentrated in the middle area of the condenser tube bundle. The other tube bundles can basically not be cleaned by the rubber balls, thus forming dirt and causing blockage of the cooling tubes.

[0007] (2) The butterfly-shaped ball collection net adopts an open-close design. Due to the large net surface, under the long-term impact of the circulating water, the net surface is extremely easy to deform, resulting in incomplete closure and ball leakage.

[0008] (3) Since the ball collection device has an open-close design of the net plate, the ball collection net plate is closed when the rubber ball device is running and opened when the operation ends. Due to the structure of the condenser, there are certain dead corners in the water chamber. A small amount of rubber balls come back slowly during the ball collection process and are lost after the net plate is opened when the rubber ball device operation ends, resulting in a gradual decrease in the ball collection rate, which is more obvious especially in winter when the circulating water flow is small.

[0009] (4) As Figure 4 shown, the ball collection net plate adopts a long-strip hole design. Rubber sponge balls with a wet state diameter slightly larger than the inner diameter of the condenser tube bundle by 1-2 mm are used. When the rubber balls are fully soaked, they become soft and swollen due to the water pressure, and the rubber balls get stuck in the holes of the ball collection net. After a long time, the rubber balls are squeezed into long strips and run away from the holes.

[0010] (5) Since the rubber balls are soaked and used for cleaning in water for a long time, the specific gravity of the rubber balls becomes heavier and heavier with the use time, and finally they cannot be in a semi-suspended state and sink to the bottom of the water chamber, resulting in the failure to smoothly recover the rubber balls.

[0011] (6) Since the ball collection port is arranged on both sides of the circulating pipe, the water flow velocity at this place is the lowest, resulting in the failure to timely recover the rubber balls.

[0012] (7) The rubber balls enter from the tube bundle in the front water chamber of the condenser and flow into the tube bundle on the water outlet side along the water flow. The cleaning is also concentrated in the area with a faster flow velocity.

[0013] (8) The degree of automation is low, and manual participation is required for each operation. Utility Model Content

[0051] Compared with the prior art, the utility model has the following beneficial effects:

[0052] 1.

The rubber balls first enter the most favorable point in the middle of the water chamber. Since the diameter of the rubber balls is larger than the inner diameter of the cooling pipes, the rubber balls entering the cooling pipes form a certain water resistance, and the flow rate of the adjacent tube bundles increases. The rubber balls then enter the cooling pipes with an increased flow rate, thus making the probability of the rubber balls entering all the cooling pipes equal, enabling all the cooling pipes to be comprehensively cleaned; it solves the problem that the existing rubber ball cleaning device cannot comprehensively clean all the cooling pipes, especially the cleaning effect of the tube bundles on the water outlet side is worse than that of the tube bundles on the water inlet side.

[0055] 4. By using PLC to control the operation of all the pumps, motors, valves and air compressors in the entire cleaning device, the problem of low automation degree is solved.

[0056] 5. By using PLC to control the vacuum pump and the dehydration valve, the dehydration process can end when the rubber balls maintain a reasonable water content, solving the problem that in the existing rubber ball cleaning device, the rubber balls are soaked for too long, the specific gravity increases and they cannot maintain a semi-suspended state, resulting in poor cleaning effect.

[0098] As Figures 2 - 3 shown, the ball catcher includes a housing 44, a rotating shaft 45, a hollow ball receiving box 46, a conical filter screen 47, an upper ball receiving pipe 48, a lower ball receiving pipe 49, and a transmission device 50.

[0099] Inside the housing 44, there is a rotating shaft 45. The rotating shaft 45 has a hollow structure. The top and bottom of the rotating shaft 45 are respectively connected to the vertical parts of the upper ball collecting pipe 48 and the lower ball collecting pipe 49 through bearing sleeves. Under the action of the bearing sleeves, the upper ball collecting pipe 48 and the lower ball collecting pipe 49 are communicated with the rotating shaft 45 but do not rotate with the rotating shaft 45. The ends of the horizontal parts of the upper ball collecting pipe 48 and the lower ball collecting pipe 49 extend out of the housing 44 to serve as the upper ball collecting port and the lower ball collecting port.

[0100] The upper ball collecting pipe 48 and the lower ball collecting pipe 49 are fixedly installed inside the housing 44. Inside the housing 44, a conical filter screen 47 is also fixedly installed. The conical filter screen 47 is coaxially arranged with the rotating shaft 45.

[0101] A number of openings are provided on the shaft wall of the rotating shaft 45 from top to bottom, so that the hollow part inside the rotating shaft 45 is communicated with the outside. The openings are within the height range of the conical filter screen 47.

[0102] The transmission device 50 includes a motor, a driving gear, and a driven gear. The output shaft of the motor is connected to the driving gear. The driving gear and the driven gear are connected by a chain. The driven gear is coaxially fixed on one end of a driven rod. The upper end of the one end of the driven rod passes through the lower ball collecting pipe 49 and is installed on the inner wall of the lower end of the rotating shaft 45 through a bracket.

[0103] The inner wall of the upper end of the rotating shaft 45 is fixedly connected to a second section of the driven rod through a bracket. The top of the second section of the driven rod is rotatably installed on the upper ball collecting pipe 48.

[0104] In this embodiment, the motor is arranged on the outer wall of the housing 44. The chain passes through the housing 44, and a sealing ring is provided between the chain and the housing 44.

[0105] Symmetric hollow ball collecting boxes 46 are provided on the rotating shaft 45. The front view of the hollow ball collecting box is triangular and matches the conical filter screen 47. There is a gap between the outside of the hollow ball collecting box 46 and the conical filter screen 47. The plate surface of the hollow ball collecting box 46 is L-shaped.

[0106] The mesh holes on the conical filter screen 47 are regular hexagonal mesh holes. When the hollow ball collecting box 46 rotates, the rubber balls stuck on the filter holes and the rubber balls attached to the mesh surface are recovered. By using a fixed conical filter screen 47 with regular hexagonal mesh holes, when the rubber balls are attached to the mesh surface, the deformation is within a controllable range, and they cannot escape from the mesh holes. Moreover, they are easily recovered during the contact with the hollow ball collecting box 46, solving problems such as rubber ball running, leaking, jamming, and loss.

[0107] The top opening of the housing 44 is a water return port. The circulating water discharged from a section of the circulating water outlet pipe enters the housing 44. The projection of the water return port is within the coverage range of the conical filter screen 47.

[0108] The rubber balls moving along with the circulating water fall into the conical strainer 47. The rotating shaft 45 drives the hollow ball collecting box 46 to rotate relative to the conical strainer 47, collects the rubber balls into the hollow ball collecting box 46 and enters the rotating shaft 45 through the opening, and is collected into the service ball tank along the upper ball collecting pipe 48 and the lower ball collecting pipe 49 under the action of the ball collecting pump.

[0109] The working process of the utility model is as follows:

[0110] A complete working cycle is divided into 2 sub-working cycles: the ball sending, collecting, and rubber ball dehydration process in the front water chamber on the A side; immediately following that, the ball sending, collecting, and rubber ball dehydration process in the rear water chamber on the A side ends; after an interval of 30 seconds to 60 seconds, it automatically switches to the ball sending, collecting, and rubber ball dehydration process in the front water chamber on the B side; the completion of the ball sending, collecting, and rubber ball dehydration process in the rear water chamber on the B side marks the end of one cleaning, and the rubber ball device enters the next cycle standby timing mode. When the preset interval time arrives, the system automatically runs again to achieve a closed loop without manual operation.

[0111] (1) Ball sending in the front water chamber: Sequentially open the exhaust valve 18 of the compressed air energy storage tank 38, exhaust valve A, the exhaust valve A15 of the front service pipe, communication valve A3, service valve A8, the inlet valve A11 of the front water chamber, and finally open the water injection valve 2 (alternately shared when receiving and sending balls on both the A and B sides), and perform the water filling operation until water overflows from the exhaust valve 18 of the compressed air energy storage tank 38, exhaust valve A, and the exhaust valve A15 of the front service pipe for 5 - 10 seconds and then stop water filling. At the same time, send the rubber balls along the water flow to the front service valve A12 of the water chamber (the installation position is near the front water chamber A of the condenser 43), and sequentially close the exhaust valve 18A of the compressed air energy storage tank 38, exhaust valve A, the exhaust valve A15 of the front service pipe, and water injection valve 2. Sequentially open the front service valve A12 of the water chamber and the pressurizing valve (alternately shared when receiving and sending balls on both the A and B sides), and use compressed air as the power to push the water in the compressed air energy storage tank 38 and the receiving and sending ball tank through the service pipeline to launch the rubber balls into the water chamber of the condenser 43 (the compressed air pressurizing time is set at about 0.5 - 5 seconds), and then close the pressurizing valve, communication valve A3, service valve A8, the inlet valve A11 of the front water chamber, and the front service valve A12 of the water chamber. So far, the ball sending process in the front water chamber ends.

[0112] (2) Ball collection in the front water chamber: Before starting the ball collection pump, it is necessary to fill the ball receiving and sending tank and the pipeline connected to the ball collection pump with water. The process is as follows: Open the exhaust valve 18A of the compressed air energy storage tank 38, exhaust valve A, communication valve A3, and water injection valve 2. Stop adding water 5 - 10 seconds after water overflows from the exhaust valve. Then, close the exhaust valve 18A of the compressed air energy storage tank 38, exhaust valve A, and communication valve A3 in sequence. Next, open the ball receiving valve A7, the upper ball catching valve 17 of the ball catcher A, the lower ball catching valve 16 of the ball catcher A, the water pumping valve A6, start the ball collection pump and the motor until the rubber balls are recycled to the ball loading bucket of the A-side ball receiving and sending tank (the time setting range is 5 - 30 minutes). Then, close the ball collection pump, the motor, the ball receiving valve A7, the upper ball catching valve 17 of the ball catcher A, the lower ball catching valve 16 of the ball catcher A, and the water pumping valve A6 in sequence. The ball collection process in the front water chamber ends.

[0113] (3) Dehydration of the front water chamber: Open the exhaust valve A, drain valve A4, ball sending valve A8, inlet ball valve A11 of the front water chamber, and exhaust valve A15 of the front ball sending pipe for drainage. After the drainage is completed, close the exhaust valve A, drain valve A4, ball sending valve A8, inlet ball valve A11 of the front water chamber, and exhaust valve A15 of the front ball sending pipe. Open the outlet valve 35 of the vacuum pump. After starting the vacuum pump to establish a vacuum, open the inlet valve 34 of the vacuum pump and the dehydration valve A5 in sequence until the rubber balls maintain a reasonable water content. Then, close the dehydration valve A5, the inlet valve 34 of the vacuum pump, the vacuum pump, and the outlet valve 35 of the vacuum pump in sequence. Up to this point, the ball receiving and sending process in the front water chamber ends, and immediately enters the ball receiving and sending process of the rear water chamber.

[0114] (4) Ball sending in the rear water chamber: Open the exhaust valve 18A of the compressed air energy storage tank 38, exhaust valve A, exhaust valve A of the rear water chamber ball sending pipe, communication valve A3, ball sending valve A8, inlet ball valve A10 of the rear water chamber, and finally open the water injection valve 2 (alternately shared during AB-side ball receiving and sending) for the water addition operation. Stop adding water 5 - 10 seconds after water overflows from the exhaust valve 18A of the compressed air energy storage tank 38, exhaust valve A, and exhaust valve A of the rear water chamber ball sending pipe. At the same time, send the rubber balls along the water flow to the ball sending valve A13 of the rear water chamber (the installation position is near the rear water chamber A of the condenser 43). Then, close the exhaust valve 18A of the compressed air energy storage tank 38, exhaust valve A, exhaust valve A15 of the front ball sending pipe, and water injection valve 2 in sequence. Open the ball sending valve A12 of the front water chamber and the pressurizing valve (alternately shared during AB-side ball receiving and sending) in sequence. Using compressed air as the power, push the water in the compressed air energy storage tank 38 and the ball receiving and sending tank through the ball sending pipeline to launch the rubber balls into the water chamber of the condenser 43 (the compressed air pressurizing time is set at about 0.5 - 5 seconds). Close the pressurizing valve, communication valve A3, ball sending valve A8, inlet ball valve A10 of the rear water chamber, and ball sending valve A13 of the rear water chamber. Up to this point, the ball sending process in the front water chamber ends.

[0115] (5) Ball collection in the rear water chamber: Before the ball collection pump is turned on, the ball receiving and sending tanks and the pipes connected to the ball collection pump need to be filled with water. The process is as follows: Open the exhaust valve 18A, exhaust valve A, connecting valve A3, and water injection valve 2 of the compressed air storage tank 38. Stop adding water after water overflows from the exhaust valve for 5-10 seconds. Close the exhaust valve 18A, exhaust valve A, and connecting valve A3 of the compressed air storage tank 38 in sequence. Then open the ball collection valve A7, the upper ball collection valve 17 of the ball catcher A, the lower ball collection valve 16 of the ball catcher A, and the water pumping valve A6. Start the ball collection pump and motor until the rubber balls are recovered and loaded into the ball barrel of the ball receiving and sending tank on the A side (the time setting range is 5-30 minutes). Close the ball collection pump, motor, ball collection valve A7, the upper ball collection valve 17 of the ball catcher A, the lower ball collection valve 16 of the ball catcher A, and the water pumping valve A6 in sequence. The ball collection process in the front water chamber is completed (the ball collection process in the front and rear water chambers is the same).

[0116] (6) Dehydration of the rear water chamber: Open the exhaust valve A, the sewage valve A4, the ball valve A8, the rear water chamber ball valve A10, and the exhaust valve A of the rear water chamber ball pipe to drain water until no water flows out of the sewage valve A4. After the drainage is completed, close the exhaust valve A, the sewage valve A4, the ball valve A8, the rear water chamber ball valve A10, and the exhaust valve A of the rear water chamber ball pipe. Open the vacuum pump outlet valve 35, start the vacuum pump to establish vacuum, and then open the vacuum pump inlet valve 34 and the dehydration valve A5 in sequence until the rubber balls maintain a reasonable water content. Then close the dehydration valve A5, the vacuum pump inlet valve 34, the vacuum pump, and the vacuum pump outlet valve 35 in sequence. At this point, the ball receiving and sending process on the condenser 43A side is completed.

[0117] (7) Receiving and serving the ball on the condenser 43B side: After the receiving and serving process on the condenser 43A side is completed, it will automatically switch to the receiving and serving of the ball on the condenser 43B side after a certain period of time (the time can be set to 30-60 seconds). The receiving and serving process on the condenser 43B side is the same as that on the condenser 43A side. After the receiving and serving process on the condenser 43B side is completed, it will enter the next automatic operation to timing, with a time interval of 5-20 minutes.

[0118] In this utility model, under the control of a PLC microcomputer program, water circulation is utilized to intermittently launch cleaning balls into the inlet of condenser 43 24 hours a day, wiping and cleaning all cooling pipes of condenser 43. The cleaned balls are then collected by a ball collector. A single cycle lasts only approximately 15 to 30 minutes, and a cycle is performed every 20 to 30 minutes. This intermittent operation is repeated 20 to 30 times throughout the day, meaning that the cooling pipes of condenser 43 are cleaned every 20 to 30 minutes.

[0119] It is worth noting that, based on the above structural design, in order to solve the same technical problem, even if some insubstantial improvements are made on the basis of the present invention, they also fall within the scope of protection of the present invention.
