Description

Technical Field

[0001] The invention relates to the technical field of cleaning control of inner wall of a multiple-effect distiller, and in particular to a control mechanism and a use method of a salt dehydration device. Background Art

[0002] In the production process of thermal power plants, key equipment such as boilers and steam turbines require high-purity water to ensure the normal operation of the equipment and extend its service life. Therefore, a large amount of desalinated and impurity-free water is required to ensure the purity of the water quality. Using desalted water as a cooling medium can reduce scaling and corrosion in the cooling system and improve cooling efficiency.

[0003] In the production process of thermal power plants, a large amount of high-temperature steam will be generated. Therefore, multiple-effect distillation and other methods are often used to desalinate and dehydrate water, purify water and improve water quality. Water resources that meet cooling needs such as cooling can be obtained through multiple multiple-effect distillation equipment. In the process of distilling water, impurities in the water often remain in the cavity of the distiller, causing salt to remain in the cavity of the distiller. The concentrated cavity is in contact with the side walls and bottom walls for a long time, which may cause corrosion to the tank body. Therefore, it is necessary to clean the interior of the distiller from time to time. The control mechanism needs to be able to collect and process parameters and information of each link in the production process to optimize production efficiency. At the same time, it is also necessary to consider the issue of reducing production costs. It is necessary to control existing actuators and use existing resources to reduce production costs. Steam is a by-product of thermal power processing and has a lower cost than electricity. If the interior of the distiller can be cleaned by controlling the flow direction and flow rate of steam energy, the cost of desalination and dehydration can be reduced to a certain extent.

[0004] Therefore, it is necessary to invent a control mechanism and a method for using a salt dehydration device to solve the above problems. Summary of the invention

A pressing rod 508 located at the bottom of the triangular block 505 and extending to the inside of the middle channel 5042, and an extension arm 517 detachably mounted on the bottom of the pressing rod 508 for driving the transmission rod 502 to synchronously slide in the vertical direction. The transmission rod 502 can rotate around the contact point of the extension arm 517. The clamping end of the transmission rod 502 is arranged in a ring shape, which can ensure its rotation effect while driving it to slide vertically, thereby ensuring the transmission effect on the output gear 503. The U-shaped tube 518 is connected with the middle cavity 514 and the lower cavity 515, so that when the water flows through the middle cavity 514 to the lower cavity 515, it can vertically blow the transmission blades 516 to ensure that there is enough impact force to drive the blades to rotate.

[0040] The control box 501 is further provided with an upper cavity 513, a middle cavity 514, and a lower cavity 515. A connecting groove 510 located on one side of the middle cavity 514 is opened on one side of the middle cavity 514. The extension arm 517 extends to the inside of the middle cavity 514 through the connecting groove 510 and clamps the transmission rod 502. The end face of the transmission rod 502 located in the lower cavity 515 is connected to the transmission fan blade 516. The lower cavity 515 is connected to the lower channel 5043.

The lower cavity 515 is connected to the lower channel 5043, which can ensure that the transmission blade 516 has sufficient rotation space. The transmission rod 502 is driven to slide by the extension arm 517 to adjust the position of the transmission blade 516, thereby further controlling the transmission power of the output gear 503.

[0042] A receiving groove 509 for receiving the triangular block 505 is provided inside the upper channel 5041, and a reset push plate 506 for driving the triangular block 505 to reset is provided inside the receiving groove 509, and a plurality of reset springs 507 are provided at the bottom end of the reset push plate 506, and guide columns 512 for vertical sliding are provided at the multiple corners of the triangular block 505; when the reset push plate 506 is in the reset state, the top of the triangular block 505 fits with the top of the upper channel 5041, and when the triangular block 505 is located inside the receiving groove 509, the fluid can flow out through the upper channel 5041, and the device of the guide column 512 can prevent the triangular block 505 from flipping and deflecting, etc. The cleaning pipe 2 also includes a pipe four 207 connected with the pipe two 202 and the bottom wall cleaning component 4.

The rotation range of the bottom scraper 401 will not interfere with the guide block 302, thereby avoiding collision during the rotation process.

[0043] The multi-effect distiller body 1 also includes a distiller shell 102, and the side wall cleaning component 3 includes a guide block 302 installed on the inner wall of the distiller shell 102. The portion between the guide block 302 and the distiller shell 102 is provided with a plurality of threaded rods 303 that can rotate synchronously. The plurality of threaded rods 303 are commonly threadedly connected with an annular scraper 301. The end face of the annular scraper 301 is in contact with the inner wall of the distiller shell 102. The bottom end of the threaded rod 303 extends to the bottom end of the distiller bottom wall 101 and is sleeved with a transmission gear 304 that can drive it to rotate. A driven gear 306 meshing with the driven gear 304 is provided on one side of the driven gear 304 close to the output gear 503.

The synchronous gear ring 305 is used to ensure the synchronous rotation of multiple threaded rods 303, so that the annular scraper 301 can fit with the end face of the distiller shell 102 to maintain the cleaning effect on the side wall.

[0044] A synchronous gear ring 305 meshing with multiple transmission gears 304 is installed at the bottom end of the distiller bottom wall 101; when the driven gear 306 rotates, the synchronous gear ring 305 can drive the remaining transmission gears 304 to rotate synchronously, and the synchronous gear ring 305 drives the remaining transmission gears 304 to rotate synchronously, and the transmission gear 304 drives the threaded rod 303 to rotate, driving the annular scraper 301 to clean the inner wall of the distiller shell 102.

[0045] The outer side of the pipe four 207 is provided with a solenoid valve two 205 for controlling its opening, and the top of the solenoid valve two 205 is provided with a one-way valve 206 for preventing liquid reflux, and the bottom end of the bottom scraper 401 is provided with a plurality of spray holes 402 for flushing the bottom wall 101 of the distiller, and the spray holes 402 are connected with the pipe four 207. The bottom end of the bottom wall 101 of the distiller is also installed with a drainage pipe 103 for discharging waste water, and the setting of the spray holes 402 can utilize the impact force of steam or flushing water to clean the bottom wall, thereby improving the cleaning effect.

[0046] The cleaning pipeline 2 also includes a pipeline three 203 which is connected to the pipeline one 201 and the upper cavity 513 respectively. The pipeline three 203 is equipped with a solenoid valve one 204 for controlling its opening. The upper cavity 513 is provided with a connecting hole 511 at a portion adjacent to the upper channel 5041. When the pipeline three 203 is in an open state, the fluid can flow out through the pipeline three 203, the upper cavity 513, the connecting hole 511, the upper channel 5041 and the pipeline two 202 in sequence. When the pipeline three 203 is in an open state, when the steam is blocked on one side and open on the other side, it will tend to choose a path with less resistance to flow out, and can flow out through the open channel, thereby avoiding the reduction of impact force caused by the impact on the transmission blades 516 during the flow process, resulting in insufficient driving force when flowing to the remaining distiller, resulting in the inability to effectively drive the cleaning components.

[0047] The present invention provides a control mechanism and a method for using a salt dehydration device, step S1: a cleaning pipe 2 and a control component 5 are respectively installed at the bottom ends of a plurality of multiple-effect distiller bodies 1, and a pipe 2 202 is respectively connected to a pipe 1 201 at the bottom ends of the other multiple-effect distiller bodies 1, and the ends of the cleaning pipe 2 are respectively connected to a steam pipe and flushing water, and are connected to a pressure pump for controlling the flow rate; Step S2: When the cleaning function needs to be debugged, the flow rate of the fluid is controlled so that the fluid impacts the triangular block 505 at different flow rates, and the triangular block 505 slides downward, driving the transmission rod 502 and the output gear 503 to adjust their positions; Step S3: When the output gear 503 moves to mesh with the driven gear 2 405, the transmission gear 2 403 can drive the bottom scraper 401 to rotate, so that the liquid inside the tank body is heated evenly; Step S4: When the output gear 503 moves to the point where the driven gear 2 405 is meshed with the driven gear 1 306, it can drive the bottom scraper 401 and the annular scraper 301 to work and clean the inner wall and side wall of the tank body; Step S5: The solenoid valve 1 204 controls the pipeline 3 203 to be opened, and the fluid can flow to the pipeline 2 202 through the pipeline 3 203, the output gear 503 is in an idle state, and the cleaning component stops working. After the fluid passes through the control component 5, it can be used for cleaning the rest of the multiple-effect distiller body 1; Step S6: When the solenoid valve 205 is opened, steam and flushing water can be transported to the interior of the tank body. In the process of draining water, injecting steam into the interior of the tank body can accelerate the discharge of waste water. At the same time, the spray hole 402 faces the bottom wall 101 of the distiller, which can improve the cleaning effect. By injecting flushing water, the residue can be flushed and cleaned after the waste water is discharged.

[0048] The flushing water can be recycled water collected after steam condensation. By using steam and flushing water to push the triangular block 505, the position of the transmission rod 502 can be controlled. Through the rotation of the transmission fan blades 516, the components that need to be cleaned can be driven to work. When the flow rate is low, the output gear 503 can drive the bottom scraper 401 to rotate at a lower speed, which can effectively prevent impurities from precipitating and solidifying on the bottom wall 101 of the distiller during the distillation process, and help to extend the life of the equipment.

[0049] According to the present invention, when the pipe 3 203 is closed, the triangular block 505 can be impacted by controlling steam and flushing water, so that the extension arm 517 drives the transmission rod 502 to move to different positions, and the transmission fan blades are driven to rotate by steam and flushing water, so as to drive different cleaning components to work. During the distillation process, the liquid inside the tank body can be driven to flow by controlling the rotation of the bottom scraper 401, so that the internal temperature of the tank body is uniform and the distillation efficiency is improved; during the wastewater discharge process, by injecting steam into the tank body while the bottom scraper 401 rotates and cleans, a faster drainage effect can be achieved, and the work efficiency is improved; during the cleaning process, the bottom wall cleaning component 4 and the side wall cleaning component 3 work to clean the residue inside the cavity; when other multi-effect distiller bodies 1 need to be cleaned, the flow rate consumption during the flow process is reduced by controlling the circulation of the pipe 3 203, so as to ensure that different multi-effect distiller bodies 1 can be cleaned, and by using steam and flushing water as the power source for cleaning the multi-effect distiller body 1, energy can be reused, waste gas emissions can be reduced, and maintenance costs can be reduced.
