Description

Technical Field

[0001] This utility model relates to the field of boiler equipment technology, and in particular to a makeup water treatment device for a cogeneration boiler. Background Technology

[0002] Combined heat and power (CHP) is a highly efficient energy utilization method that uses waste heat generated during power generation for heating, achieving cascaded energy utilization, improving energy efficiency, and reducing environmental pollution. In a CHP system, the boiler is one of the core pieces of equipment; its operational stability and efficiency directly affect the performance of the entire CHP system. While existing feedwater treatment devices for CHP boilers are generally sufficient to meet daily operating needs, some shortcomings still require improvement.

[0003] Commercially available cogeneration boiler feedwater treatment systems use reverse osmosis (RO) components to remove various contaminants from the feedwater. However, with prolonged use, the surface of the RO membrane gradually becomes covered by contaminants, or the membrane structure changes, leading to a decrease in its ability to retain salt and other impurities, resulting in a lower desalination rate. Consequently, the RO components need to be disassembled and replaced. Most RO components are tubular in design and quite long, requiring multiple people to work together to lift the components and align the pipes during disassembly and installation, making the replacement process cumbersome. To address these issues, we propose a cogeneration boiler feedwater treatment system. Utility Model Content

[0009] As an improved technical solution, a control panel is installed on the front right side of the water supply treatment tank, and the input terminals of the servo motor and the linear driver are electrically connected to the control panel through wires.

[0010] As an improved technical solution, the inner wall of the guide sleeve is polished, and the outer wall of the connecting plate is glued with an anti-slip rubber sleeve.

[0028] Figures 1 to 5As shown, this embodiment provides a feedwater treatment device for a cogeneration boiler, including a feedwater treatment tank 1, a reverse osmosis chamber 2 and a pretreatment chamber 3 disposed within the feedwater treatment tank 1. Multiple sets of pipes 4 are installed within the reverse osmosis chamber 2, and each set of pipes 4 contains a reverse osmosis assembly 5. A guide rail 6 is fixed to the top of the feedwater treatment tank 1. A servo motor 7 is installed on the outer wall of the left end of the guide rail 6. A lead screw 8 is rotatably connected inside the guide rail 6, and the input end of the servo motor 7 is connected to the end of the lead screw 8. A guide slider 9 is slidably connected inside the guide rail 6. The guide slider 9 has a threaded hole 10. The guide slider 9 is threadedly connected to the lead screw 8 through the threaded hole 10. A linear actuator 11 is installed at the front end of the guide slider 9. The output end of the linear actuator 11 is connected to a guide sleeve 12. Both sides of the bottom end of the guide sleeve 12 have a storage groove 13. An extension rod 14 is slidably connected in both sets of storage grooves 13. A connecting plate 15 is installed at the front end of both sets of extension rods 14. Locking components are provided on both sides of the bottom end of the guide sleeve 12.

[0029] By installing a guide sleeve 12 with a quick-adjustable position on the makeup water treatment tank 1, the guide sleeve 12 can be quickly moved to the required position when the reverse osmosis component 5 is disassembled, and the guide sleeve 12 can support the reverse osmosis component 5. Furthermore, by installing a telescopic extension rod 14 and a connecting plate 15 at the front end of the guide sleeve 12, the two sets of extension rods 14 and connecting plate 15 can further support the reverse osmosis component 5. When installing the reverse osmosis component 5, the reverse osmosis component 5 can be quickly inserted into the guide sleeve 12 on the connecting plate 15, and the guide sleeve 12 guides the reverse osmosis component 5 to accurately enter the pipeline 4. This effectively simplifies the replacement steps, reduces the difficulty of replacing the reverse osmosis component 5, and improves the convenience of using the device.

[0030] In other embodiments, the locking assembly includes sleeves 16 fixed on both sides of the guide sleeve 12, movable blocks 17 disposed inside the two sets of sleeves 16, and locking plates 18 fixed at the front ends of the two sets of movable blocks 17. The opposite ends of the two sets of extension rods 14 are provided with slots 19. The opposite ends of the two sets of locking plates 18 can be inserted into the slots 19 on the two sets of extension rods 14. The two sets of sleeves 16 are provided with return springs 20. The outer walls of the front ends of the two sets of locking plates 18 are fixed with push plates 21.

[0031] By installing laterally movable locking plates 18 on both sides of the guide sleeve 12, the two sets of locking plates 18 can be quickly inserted into the slots 19 on the two sets of extension rods 14 under the elastic force of the return spring 20, effectively fixing the movable position of the two sets of extension rods 14, thereby ensuring the stability of the two sets of extension rods 14 during use.

[0032] In other embodiments, a control panel 22 is installed on the right side of the front end of the water supply treatment tank 1, and the input terminals of the servo motor 7 and the linear driver 11 are electrically connected to the control panel 22 through wires.

[0033] This design enables the control panel 22 to control the start and stop of the servo motor 7 and the linear driver 11 in real time, ensuring that the servo motor 7 and the linear driver 11 can be used normally.

[0034] In other embodiments, the inner wall of the guide sleeve 12 is polished, and the outer wall of the connecting plate 15 is glued with an anti-slip rubber sleeve.

[0035] With this design, when the reverse osmosis component 5 moves laterally along the inside of the guide sleeve 12, it can effectively prevent the guide sleeve 12 from causing wear on the surface of the reverse osmosis component 5, while the connecting plate 15 can increase the friction between its exterior and the outer wall of the reverse osmosis component 5, preventing the reverse osmosis component 5 from slipping off the connecting plate 15.

[0036] like Figure 5 As shown, the two ends of the return spring 20 are respectively connected to the outer wall of the movable block 17 and the inner wall of the sleeve 16, and the movable block 17 is elastically connected to the inner wall of the sleeve 16 through the return spring 20.

[0037] This design allows the two sets of return springs 20 inside the two sets of sleeves 16 to continuously apply opposing elastic forces to the two sets of movable blocks 17, enabling the two sets of movable blocks 17 to drive the two sets of locking plates 18 to quickly insert into the slots 19 on the two sets of extension rods 14.

[0038] In other embodiments, the outer wall of the card plate 18 can fully fit against the inner wall of the slot 19 on the extension support rod 14;

[0039] With this design, when the end of the card plate 18 is inserted into the slot 19 on the extension rod 14, the card plate 18 can provide a stable limiting effect on the extension rod 14.

[0040] like Figure 5 As shown, the diameter of the movable block 17 is the same as the inner diameter of the sleeve 16, and the movable block 17 and the sleeve 16 are slidably connected.

[0041] With this design, when the movable block 17 drives the card plate 18 to move laterally along the sleeve 16, it can effectively prevent the movable block 17 from shaking significantly during the movement, thus improving the stability of the movable block 17 during movement.

[0042] This utility model provides a feedwater treatment device for a cogeneration boiler, the specific working principle of which is as follows:

[0043] When the reverse osmosis component 5 needs to be replaced, the servo motor 7 can be driven by the control panel 22 to rotate the lead screw 8. This causes the guide slider 9 to move laterally under the action of the thread, and the linear actuator 11 moves the guide sleeve 12 to the front end of the reverse osmosis component 5 to be disassembled. Then the reverse osmosis component 5 can be disassembled, and the guide sleeve 12 can support the disassembled reverse osmosis component 5. The extension rod 14 and the connecting plate 15 at the front end of the guide sleeve 12 extend the supporting length of the guide sleeve 12, thereby effectively preventing the reverse osmosis component 5 from falling accidentally after it is completely detached from the guide sleeve 12. After the reverse osmosis component 5 is completely disassembled, one end of the replacement reverse osmosis component 5 can be placed on the connecting plate 15, and the end of the replacement reverse osmosis component 5 can be pushed so that the reverse osmosis component 5 can be inserted into the guide sleeve 12 through the connecting plate 15. Under the guidance of the guide sleeve 12, it can be quickly inserted into the corresponding pipe 4, thereby effectively shortening the time required to replace the reverse osmosis component 5. The operation is then completed.

[0044] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.

[0045] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
