Description

Technical Field

[0001] This utility model relates to the field of energy-saving technology for steam generators, specifically a device for recycling and reusing wastewater from steam generators. Background Technology

[0002] Steam boilers, sometimes called steam generators, are an important component of steam power plants. Power plant boilers, steam turbines, and generators are the main components of thermal power plants. Therefore, power plant boilers are important equipment for producing electricity. Industrial boilers are indispensable equipment in various industrial enterprises for providing the steam needed for production and heating.

[0003] When a steam generator is running, it usually separates steam and condensate with a steam-water separator while generating steam. In addition, a small amount of impurities are also generated during the process of heating water in the coil. These substances need to be discharged multiple times through the drain valve. These discharges are usually directly discharged into the sewage well, resulting in the long-term waste of water resources. Utility Model Content

[0043] Please see the appendix Figure 1 -Appendix Figure 9 This utility model discloses a steam generator wastewater recycling and reuse device, comprising a conveying pipeline 1, one end of which is connected to a supply device 2, and the other end is connected to a separator 3, so that the supplied gas flows through the separator 3 for gas and condensate separation:

[0044] The emission device 4 is connected to the separator 3 and is used to discharge the separated gas.

The filter chamber 51 is connected to the separator 3 so that the separated condensate flows into the filter chamber 51.

[0046] The cleaning component 6 is located on the sealing cover 52. By controlling its movement on the filter component 5, impurities on the filter component 5 can be scraped off.

[0047] A water storage tank 7 is connected to one side of the filter chamber 51. The water storage tank 7 has a drain pipe 8 for draining the condensate in the water storage tank 7.

[0063] Specifically, the connecting plate 651 and the rubber scraper 652 are detachably connected by bolts, and the rubber scraper 652 is made of neoprene rubber in one piece.

[0064] Working principle:

[0065] First, steam is supplied to the delivery pipeline 1 via a supply device, and then flows from the delivery pipeline 1 into the separator 3 for separation of gas and condensate. The separated gas is fed into the discharge device 4 through a connecting delivery pipe for treatment and discharge, while the separated condensate flows into the filter chamber 51 through a delivery pipe connecting the separator 3 and the filter chamber 51.

[0066] Unfiltered condensate in filter chamber 51 flows from top to bottom through filter plate 56. As the unfiltered condensate flows through each filter plate 56 in sequence, the condensate flows from the bottom side of filter plate 56 into the bottom of filter chamber 51, and then flows into water storage tank 7 through the conveying pipe connecting filter chamber 51 and water storage tank 7. The condensate in water storage tank 7 is then discharged through drain pipe 8, thus completing the filtration of condensate.

[0067] Remove the sealing plate on the drain pipe 10, and then start the servo motor 61. The output shaft of the servo motor 61 rotates synchronously, driving the pulley drive component 62 to rotate. The pulley drive component 62 drives the lead screw 63 to rotate inside the sealing cover 52. When the lead screw 63 rotates, it engages and drives the connecting plate 651 to move on the outer wall of the guide rod 64. While the connecting plate 651 is moving, it drives the rubber scraper 652 to move on the top surface of the filter plate 56 to the side close to the drain pipe 10. When the rubber scraper 652 moves on the top surface of the filter plate 56, it scrapes up the impurities on the plate and pushes them towards the drain hole 9. When the impurities pass through the drain hole 9, they flow into the drain pipe 10, and then the impurities are discharged from the drain pipe 10.

[0068] Remove the bolts connecting the filter chamber 51 and the sealing cover 52, and then remove the sealing cover 52 along with the cleaning assembly 6. Use the handle to lift the placement frame 54, along with the internal filter plate holder 55 and filter plate 56, from the placement frame 53 and move it to the outside of the filter chamber 51. Then use the handle to remove the filter plate holder 55 from the placement frame 54. Next, remove the old filter plate 56 from the positioning pin 551, and put the new filter plate 56 into the positioning pin 551 so that the limiting hole 11 of the filter plate 56 is aligned with the positioning pin 551 and put into place. At this point, the entire process is complete.
