Description

Technical Field

[0001] The present invention relates to the technical field of sludge treatment in nuclear power plants, and specifically to a cleaning device for sludge and a cleaning method therefor. Background Technique

[0002] Nuclear power plants rely on a large amount of water to cool reactors and auxiliary equipment. During the normal operation of nuclear power plants, radioactive substances may mix into the cooling water or other process water. These radioactive substances may then enter different systems along with the water flow and eventually deposit in low points or specific collection areas, such as the lower part of the pump house, sumps, or sedimentation tanks to form sludge. The accumulation of sludge in the pump house and sumps of nuclear power plants will directly affect the functions of pumps and other drainage equipment. The sludge will also hinder the water flow, increase the burden on the pumping system, resulting in reduced efficiency or equipment damage. Some sludge may also enter the interior of mechanical equipment, causing wear or blockage, affecting the normal operation of the equipment, and even potentially leading to a breakdown and shutdown.

Detailed implementation manners

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Embodiment 1;

[0042] Please refer to Figures 1-3 , the present invention provides a technical solution: a cleaning device for silt, including a vehicle body 1. The vehicle body 1 is driven through a drive system. In the first mode, wheel components are used to drive the vehicle body 1; in the second mode, a crawler-type walking mechanism is arranged at the bottom of the vehicle body 1. The crawler-type walking mechanism includes a drive wheel, a guide wheel, a load-bearing wheel and a rubber crawler arranged around it. The drive wheel is connected to the drive system of the vehicle body 1 through a reduction motor. The guide wheel and the load-bearing wheel are fixed to the bottom of the vehicle body 1 through brackets. The surface of the crawler is provided with anti-slip convex patterns, thereby improving the passability and stability of the vehicle body 1 in the complex terrain of the nuclear power plant, avoiding the problems of easy slipping or sinking into the silt of the traditional wheeled structure, and ensuring the continuity and safety of the cleaning operation;

[0043] A camera 2 is riveted on the frame of the vehicle body 1. The camera 2 is wirelessly connected to a remote control terminal, which is used to automatically monitor and judge the distribution and humidity of the silt in the cleaning area and make corresponding feedback data. At the same time, the humidity parameter of the silt is obtained. A transportation component 4 is installed inside the vehicle body 1, and a collection hopper 3 is hinged to the lower inner wall of the transportation component 4;

[0044] A driving shaft 41 is fixed through both upper and lower ends of the transport component 4, and both ends of the driving shaft 41 are connected to ear seats by bearings. The bottom of the ear seat is fixed to the frame of the vehicle body 1, and one end of the driving shaft 41 located at the lower end of the transport component 4 is fixedly connected to the motor 1 through a coupling. The motor 1 is also installed on the frame of the vehicle body 1, thereby providing the necessary power source for the sludge transportation of the transport component 4.

[0045] A processing box 5 is installed on the upper surface of the vehicle body 1 at one side of the output end of the transport component 4. A number of partitions are installed from top to bottom in the processing box 5 to separate the operation flow of each part, forming a feeding area, a centrifugal chamber, a driving chamber, and a stirring chamber. The collected sludge is subjected to corresponding feeding, centrifugal drying, feeding, stirring and solidification processing operations through the processing box 5;

[0046] A feed port is provided at the center of the top of the treatment box 5, and the feed port of the treatment box 5 is aligned with the output end of the transport component 4, so that the sludge transported from the transport component 4 enters the treatment box 5. A water supply tank 10 is provided on one side of the treatment box 5;

[0047] refer to Figure 3 as well as Figure 11 A technical improvement pump 11 is arranged under the vehicle body 1. The technical improvement pump 11 is a round pancake-shaped iron welding device, weighing about 60Kg. The technical improvement pump 11 is welded with a number of downwardly inclined water spraying ports 111 around the outer side of its circular side, usually 4 or 6 water spraying ports 111. There is a space of about 70 cubic centimeters in the technical improvement pump 11, which is connected to each water spraying port 111 on its side. Two water inlet pipes 112 are installed on the upper end surface of the technical improvement pump 11. The water inlet pipes 112 are iron pipes and connected to its inner space. The water inlet pipes 112 are connected to the water supply tank 10 through a water pump pipe. Water is pumped into the technical improvement pump 11 through the water supply tank 10. After the water gathers inside the technical improvement pump 11 to form pressure, it is sprayed out from each water spraying port 111 on the side to dilute and disperse the sludge, so that these deposits can be cleaned out efficiently and the cleaning progress of the operation can be accelerated;

[0048] Among them, the driving system of the vehicle body 1, the motor 1, the water pump in the water tank 10, and the technical improvement pump 11 are all connected to the remote control terminal signal;

[0049] In this embodiment, the cleaning personnel remotely controls the vehicle body 1 through the camera 2 to clean the sludge in various places in the sludge area, remotely controls the water spraying amount of the technical improvement pump 11, and washes the sludge around the technical improvement pump 11, thereby diluting and dispersing the sludge, and then drives the vehicle body 1 to move, controls the collection bucket 3 to collect the diluted sludge, and transports it to the treatment box 5 through the transport component 4 for treatment;

[0050] refer to Figure 4 , Figure 5, symmetric sliding grooves 31 are provided on the outer walls on both sides of the collection hopper 3. Electric push rods 32 are fixedly connected to the frames on the vehicle body 1 near both sides of the collection hopper 3. The electric push rods 32 are signal-connected to the remote control terminal. A driving rod 33 is fixedly connected to the output end of the electric push rod 32. The other end of the driving rod 33 is hinged with a slider 34, and the slider 34 is slidably connected to the sliding groove 31. When the electric push rod 32 is in the Figure 4 contracted state shown, the collection end of the collection hopper 3 contacts the ground, so as to achieve the effect of shoveling up the silt. When the electric push rod 32 is in the Figure 5 extended state shown, the slider 34 slides in the sliding groove 31, and the collection end of the collection hopper 3 rotates and lifts. The lifting of the collection hopper 3 can assist the silt on it to enter the transportation assembly 4, reducing the situation of silt residue;

[0051] Specifically, after starting to work, the vehicle body 1 drives into the area to be cleaned. At this time, the collection hopper 3 is in the lifted state, and the technical transformation pump 11 starts to work. The silt around the vehicle body 1 along the preset path starts the operation of humidifying and flushing. After completing the operation of humidifying and flushing, with the help of the camera 2, it is detected whether the silt in front of the vehicle body 1 along the preset path is in a wet state:

[0052] Set the actual humidity at which the silt can be shoveled by the collection hopper 3 as v, and the silt humidity parameter obtained by the camera 2 is s. Among them, the camera 2 uses a visual analysis method to judge and give the silt humidity parameter according to the color depth of the ground silt.

[0053] When s≥v, it means that the silt is in a situation with sufficient water content. At this time, lower the collection hopper 3 and remotely control the vehicle body 1 to collect the silt, and then transport it to the treatment tank 5 through the transportation assembly 4;

[0054] When s<v, it means that the water content of the silt is insufficient and cannot be shoveled by the collection hopper 3. At this time, increase the water spray amount of the technical transformation pump 11 through the remote control terminal, humidify and flush the surrounding silt again, and obtain the silt humidity parameter s through the camera 2 again until s≥v is obtained, then stop the continuous water spraying operation and lower the collection hopper 3 for collection operation;

[0055] Through the above embodiments, the remote cleaning and automatic control of the nuclear power plant silt are realized, reducing the time for personnel to enter the nuclear power plant, and thus reducing the risk of radiation exposure to the staff.

[0056] Embodiment 2;

[0057] Reference Figure 6, at the upper end face of the processing box 5, there is a fixed connection with a blanking plate 51. The blanking plate 51 is arranged as an inclined surface facing the feeding port direction, which is convenient for the rapid entry of silt. Below the feeding port, there is a rotatably connected centrifugal cylinder 52. Both the upper and lower ends of the centrifugal cylinder 52 are conical and the middle part is cylindrical. A number of perforations are evenly arranged in the middle of the centrifugal cylinder 52. The outer side of the centrifugal cylinder 52 is connected by a bearing with a cylindrical sleeve 53, and the sleeve 53 is fixedly connected inside the processing box 5;

[0058] Reference Figure 7 , at the bottom of the centrifugal cylinder 52, there is a connecting pipe 521 installed. A driven gear 522 is sleeved on the outer side of the connecting pipe 521. On one side of the driven gear 522, there is a driving gear 523. The driven gear 522 and the driving gear 523 are arranged as meshing bevel gears. The end face of the driving gear 523 is connected by a rod body with a second motor. The second motor is installed inside the driving cavity of the processing box 5 to control the rotation speed of the centrifugal cylinder 52. The outer side of the connecting pipe 521 is connected by a bearing with a blanking pipe 55. An electric control valve one is installed inside the blanking pipe 55 for conveying the silt to the mixing cavity. A spiral blade 524 is installed on the inner wall of the centrifugal cylinder 52 to prevent the silt from directly entering the driving cavity without centrifugal operation during the blanking process and waiting to be conveyed to the mixing cavity;

[0059] Reference Figure 3 And Figure 12 , on one side of the sleeve 53, there is a perforation. A drain pipe 8 is fixedly connected inside the perforation. A flow sensor is installed inside the drain pipe 8 and is signal-connected to the remote control terminal for monitoring the discharge situation of the wastewater. And the drain pipe 8 penetrates through the outer surface of the processing box 5 and is connected with a wastewater tank 9. The wastewater tank 9 is arranged above the water supply tank 10 for collecting the excess water in the silt;

[0060] Among them, the second motor and the electric control valve one are both signal-connected to the remote control terminal;

[0061] In this embodiment, the silt quickly enters the centrifugal cylinder 52 along the inclined surface of the blanking plate 51. The second motor drives the centrifugal cylinder 52 to rotate at a high speed, so that the silt and the sewage mixed therein rotate synchronously. At this time, the silt is orderly conveyed into the blanking pipe 55 through the blade arrangement of the spiral blade 524. Among them, the opening interval time of the electric control valve one is set as a fixed value t, so as to control the amount of silt for single centrifugation. During the centrifugation process, the water in the silt is continuously thrown out and converges at the input end of the drain pipe 8. The drain pipe 8 conveys this water into the wastewater tank 9 for collection;

[0062] Reference Figure 8, one side of the sleeve 53 is penetrated and connected with an electric telescopic rod. The electric telescopic rod is signal-connected to the remote control terminal. The fixed end of the electric telescopic rod is fixed to the outer wall of the sleeve 53. The telescopic end of the electric telescopic rod faces the centrifuge cylinder 52 and is connected with a cleaning part 54. The cleaning part 54 includes a moving block and a brush fixed on the surface of the moving block;

[0063] Further, referring to Figure 6 , on the same side where the cleaning part 54 is located as the electric telescopic rod, a steam generator 6 is connected through a pipeline. The steam generator 6 is signal-connected to the remote control terminal. Referring to Figure 8 , a plurality of air holes 541 are evenly opened on the surface of the moving block connecting the brush. The high-temperature steam generated by the steam generator 6 is transported through the pipeline and discharged through the air holes 541, so that the steam contacts the centrifuge cylinder 52; when the sludge is centrifuged at a high speed in the centrifuge cylinder 52, the water in the sludge contacts the inner wall of the centrifuge cylinder 52. After the high-temperature steam contacts the inner wall of the centrifuge cylinder 52, the water is quickly evaporated, thereby realizing the preliminary drying of the sludge and avoiding the subsequent solidification effect being affected due to the sludge being too wet;

[0064] Due to the irregular particles existing in the sludge, when continuously contacting the inner wall of the centrifuge cylinder 52 during the centrifugation process, the perforations on it will be blocked. At this time, the electric telescopic rod is driven to push the cleaning part 54, and the brush of the cleaning part 54 brushes the outer wall of the centrifuge cylinder 52 when the centrifuge cylinder 52 rotates at a high speed, thereby dredging the perforations and avoiding blockage;

[0065] Specifically, set the sludge water discharge amount at a certain moment under the ideal centrifugation operation as H, and detect the sludge water discharge amount at the above-mentioned certain moment through a flow sensor in the actual state, denoted as h;

[0066] When h > H, it means that during the sludge collection process, in order to make the humidity of the sludge meet the condition of being shoveled by the collecting hopper 3, the amount of water sprayed on it is too large. At this time, the control motor two will increase the centrifugal speed, so as to avoid too much water in the sludge being unfavorable for subsequent solidification operations;

[0067] When the speed of motor two increases, the distribution of the sludge in the centrifuge cylinder 52 will further spread and it is easy to cause blockage. While the speed of motor two increases, the electric telescopic rod will increase the moving frequency of the moving block, so that the brush can contact the surface of the centrifuge cylinder 52 multiple times during the centrifugation process and play a dredging effect;

[0068] When h ≤ H, it means that the amount of water discharged during the centrifugal drying process of the sludge is in a normal state, and there is no situation of excessive water content in the sludge itself;

[0069] Through the above embodiments, the control of the water in the sludge during the centrifugal drying process is enhanced, and the drying effect is greatly improved.

[0070] Embodiment three;

[0071] refer to Figure 6 A stirring rod 56 is rotatably connected to the inner wall of the stirring chamber. The partition area in the treatment box 5 where the stirring rod 56 is located is the stirring area. A stirring motor is installed at one end of the stirring rod 56. A torque sensor is installed on the output shaft of the stirring motor to detect the stirring resistance of the sludge. A discharge pipe 57 is installed below the stirring rod 56. An electric control valve 2 is installed in the discharge pipe 57 to control the discharge of the mixed sludge. A dosing barrel 7 is provided on one side of the treatment box 5 to store and put in the curing agent required for sludge treatment; after the sludge enters the stirring area, the curing agent in the dosing barrel 7 is put in to stir and solidify the sludge;

[0072] Further, refer to Figure 9 , Figure 10 A sorting plate 71 is installed at the bottom of the dosing barrel 7. Three feeding holes with different apertures are opened on the sorting plate 71, which are the first feeding hole, the second feeding hole and the third feeding hole from small to large. A sorting assembly 72 is installed below the sorting plate 71. The sorting assembly 72 includes a connecting rod 721, which is welded to the middle of the sorting plate 71. A rotating plate 722 is fixedly connected to the outer side of the connecting rod 721. The rotating plate 722 is a plate structure with U-shaped grooves opened on all sides. A disc 723 is arranged on one side of the rotating plate 722. The side of the disc 723 close to the sorting plate 71 is fixedly connected to the rotating plate 722. A lever 724 is connected, and the other side of the disc 723 is connected to a rotating motor through a rod. A feeding pipe 73 is installed on one side below the sorting component 72. The diameter of the feeding pipe 73 is larger than the diameter of any feeding hole. The feeding pipe 73 is connected to the processing box 5 through a pipeline. A cover 74 is installed on the outer side of the sorting component 72 to protect the component. After the rotating motor is started, the disc 723 rotates and drives the lever 724 to rotate around it. During the rotation of the lever 724, it will be inserted into the U-shaped groove on the rotating plate 722 in sequence, so as to drive the rotating plate 722 to drive the sorting plate 71 to rotate intermittently.

[0073] Among them, the second electric control valve and the rotating motor are both connected to the remote control terminal signal;

[0074] In this embodiment, when the stirring rod 56 is driven to stir the sludge, the stirring resistance it encounters is fed back by the torque sensor on the stirring motor, thereby reflecting the viscosity of the batch of sludge. Then, an appropriate amount of curing agent is added according to the viscosity of the sludge, and the most suitable stirring resistance range is set to [fmin, fmax]. The stirring resistance fed back by the torque sensor is fa;

[0075] When fmin ≤ fa ≤ fmax, the sludge is in a suitable form for solidification, that is, the viscosity of the sludge is moderate. At this time, the second feeding hole is selected to input the normal dose of the curing agent and mix it with the sludge, so as to achieve the best solidification effect while saving resources;

[0076] When fa < fmin, it indicates that the viscosity of the sludge is small and the water content in it is relatively high. The relatively large amount of water will dilute the curing agent and weaken the solidification effect of the curing agent. At this time, the third feeding hole is selected to input the curing agent, so as to improve the solidification effect;

[0077] Further, based on the improvement of the sludge drying effect by increasing the rotation speed of the centrifugal cylinder 52 in Embodiment 2, when the situation of fa < fmin occurs, it indicates that this operation has not been able to dry the sludge to a suitable degree for solidification. At this time, the steam generator 6 is turned on to introduce steam into the centrifugal cylinder 52 to achieve a further drying effect, and to avoid the situation that the sludge entering the mixing chamber subsequently still has too much water content and is not suitable for solidification;

[0078] When fa > fmax, it indicates that the viscosity of the sludge is large. The first feeding hole is selected to put the minimum amount of the curing agent to avoid problems such as uneven mixing caused by too much curing agent and resulting in poor solidification effect.

[0079] By selecting the appropriate amount of the curing agent to input according to different sludge conditions in the above embodiments, the best solidification effect can be ensured. At the same time, accurately adjusting the dosage of the curing agent according to the sludge viscosity can help avoid waste of the curing agent and reduce the treatment cost. Excessive use of the curing agent not only increases the cost but may also cause unnecessary environmental burden. In addition, by correctly evaluating the sludge viscosity and adjusting the dosage of the curing agent accordingly, the mixing process can be made smoother, reducing work delays caused by uneven mixing or poor solidification, and greatly improving the treatment efficiency of the nuclear power plant sludge.

[0080] Embodiment 4;

[0081] A cleaning method for a sludge cleaning device is as follows:
