Description

Technical Field

[0001] The present application relates to a field, and in particular to a built-in steam-water dual-flow boiler. Background Art

[0002] The boiler's steam-water flow is designed as a dual-flow system, separated by a built-in startup separator. From the cold ash hopper inlet to the intermediate mixing header at an elevation of 49.327 meters, a spiral water-cooled wall is connected to the vertical tube panels of the upper furnace water-cooled wall and the rear water-cooled wall hanging tubes. The water then flows through downcomers into the flame deflection angle, the horizontal flue bottom wall, and the horizontal flue side walls, ultimately entering the steam-water separator.

[0003] Steam from the separator is directed to the ceiling and wall system before entering the low-temperature superheater. It then flows through the platen superheater and final superheater. The reheater is arranged in two sections: a low-temperature reheater and a high-temperature reheater, without a header connecting them. The low-temperature reheater is located in the front duct of the dual-stage flue, while the high-temperature reheater is located in the horizontal flue, exchanging heat with the flue gas using a combination of countercurrent and cocurrent flow.

[0004] When adding water to a dual-process steam-water boiler, tap water is first heated in a deaerator to remove oxygen and other impurities. The treated water is then pumped into the boiler via a feedwater pump. However, despite the heating process in the deaerator, some impurities may not be completely removed. Summary of the Invention

[0035] Figure 1-5 The embodiment of the present application provides a built-in steam-water dual-flow boiler, comprising a base 1, a deaerator 11 being provided on the top of the base 1, and a treatment box 12 being fixedly mounted on the upper surface of the base 1;

[0036] A box cover 13 is provided at the top of the treatment box 12, and a water injection pipe 14 is fixedly installed at the center of the top of the box cover 13. L-shaped plates 15 are fixedly installed on both sides of the inner wall of the treatment box 12, and a filter screen 16 is fixedly installed on the top of the L-shaped plate 15;

[0037] A water pump 17 is fixedly installed on the top of the base 1, and a water pipe 18 is fixedly installed on one side of the water pump 17. The side of the water pipe 18 away from the water pump 17 is fixedly connected to the processing box 12;

[0038] A water supply pipe 19 is fixedly installed on the top of the water pump 17 , and a side of the water supply pipe 19 away from the water pump 17 is fixedly connected to the deaerator 11 .

[0039] In a possible embodiment, two symmetrically distributed fixing seats 2 are fixedly installed on opposite sides of the processing box 12, and a first screw 21 is rotatably passed through the middle of each set of fixing seats 2;

[0040] The threads of the two first screws 21 are opposite to each other, and the two first screws 21 are connected by a toothed synchronous belt transmission;

[0041] The outer side of the first screw 21 is threadedly connected to a moving block 22. The processing box 12 is located at the positions of the fixed seats 2 on both sides and has a sliding groove 20 that cooperates with the moving block 22.

[0042] A connecting plate 24 is provided at the top of the connecting block 23 , a U-shaped frame 25 is fixedly mounted at the bottom edge of the connecting plate 24 , and a brush 26 is fixedly mounted at the bottom end of the U-shaped frame 25 .

[0043] In a possible embodiment, a material receiving box 27 is provided at the top of each of the two L-shaped plates 15 , and an empty slot 28 for use with the material receiving box 27 is penetrated and opened on the other two opposite sides of the processing box 12 .

[0044] In a possible embodiment, the top of the connecting block 23 is threadedly connected to the second screw 3, the top of the second screw 3 is fixedly mounted with a fixing plate 31, and the top of the fixing plate 31 is fixedly mounted with a diamond block 32;

[0045] A square groove 33 is formed through the top of the connecting plate 24, and the second screw 3 passes through the square groove 33;

[0046] Specifically, by rotating the diamond block 32, the fixing plate 31 and the second screw 3 can be driven to rotate. The second screw 3 is threadedly connected to the connecting block 23, so that the fixing plate 31 slowly moves away from the connecting plate 24. Then, when the connecting plate 24 is no longer in contact with the fixing plate 31 and the connecting plate 24 and the fixing plate 31 are in the shape of a letter "2", the connecting plate 24 and the connecting block 23 can be separated, thereby separating the connecting plate 24, the U-shaped frame 25, and the brush 26 from the connecting block 23, and the brush 26 can be replaced.

[0047] Specifically, the length and width of the square groove 33 are both longer than those of the fixing plate 31 , so that the square groove 33 on the connecting plate 24 can pass through the fixing plate 31 , thereby separating the connecting plate 24 , the U-shaped frame 25 , the brush 26 and the connecting block 23 and replacing the brush 26 .

[0048] In one possible embodiment, two symmetrically distributed trapezoidal blocks 4 are fixedly mounted on the bottom end of the box cover 13. The trapezoidal blocks 4 are located at the edge of the box cover 13. The upper surface of the processing box 12 is provided with a trapezoidal groove 41 for use with the trapezoidal blocks 4.

[0049] Specifically, by providing the trapezoidal block 4 and the trapezoidal groove 41 , it is convenient to install the box cover 13 on or remove it from the processing box 12 , and to replace the brush 26 .

[0050] In one possible embodiment, a plurality of rectangular evenly distributed first drain holes 5 are formed through the bottom end of the receiving box 27, and a plurality of evenly distributed second drain holes 51 are formed through the bottom end of the L-shaped plate 15, and the first drain holes 5 correspond to the second drain holes 51;

[0051] Specifically, by setting the first drain hole 5 and the second drain hole 51, when the impurities adsorbed on the filter screen 16 are swept into the receiving box 27, a small amount of water is also swept into the receiving box 27, and then a small amount of water is filtered through the first drain hole 5 and the second drain hole 51 to the bottom of the processing box 12 for use.

[0052] In a possible embodiment, a protective frame 6 is fixedly installed on the top of the processing box 12 outside the first screw 21;

[0053] Specifically, by setting up the protective frame 6, the first screw 21 and the synchronous belt are protected to prevent the first screw 21 and the synchronous belt from being exposed to rainwater when used outdoors, causing the first screw 21 to rust and the synchronous belt to be damaged, thereby affecting the use of the first screw 21 and the synchronous belt.

[0054] In one possible embodiment, a forward and reverse motor 7 is fixedly mounted on a side of the protective frame 6 away from the processing box 12, and a driving end of the forward and reverse motor 7 is fixedly connected to one of the first screws 21, and one of the first screws 21 is rotatably connected to the protective frame 6;

[0055] Specifically, by setting a forward and reverse motor 7, one of the first screws 21 is controlled to rotate forward and reverse, and then the other first screw 21 is driven to rotate simultaneously through a synchronous belt drive connection, so that the moving block 22, the connecting plate 24, the U-shaped frame 25, and the brush 26 can move back and forth to scrape off impurities adsorbed on the filter screen 16;

[0056] In actual use, a protective cover can be installed on the outside of the forward and reverse motor 7 to protect the forward and reverse motor 7, which is not shown in the figure.

[0057] The working principle of this utility model is as follows:

[0058] During actual use, the tap water pipe is connected to the water injection pipe 14, and then the tap water is turned on. The tap water enters the treatment box 12 from the water injection pipe 14, and then falls on the filter screen 16. The water and impurities pass through the filter screen 16, so that the water is filtered to the bottom of the treatment box 12, and the impurities are adsorbed on the filter screen 16. Then, the water filtered to the bottom of the treatment box 12 is started by the water pump 17, and the water passes through the water pump pipe 18, and then the clean water is added to the deaerator 11 through the water adding pipe 19. Then, water is added to the steam-water dual-process boiler through the deaerator 11 and the water feed pump;

[0059] When filtering tap water, at the same time, the forward and reverse motors 7 are started to drive one of the first screws 21, and then the other first screw 21 is driven to rotate simultaneously through the synchronous belt transmission connection. The rotation of the first screw 21 drives the moving block 22, the connecting plate 24, the U-shaped frame 25, and the brush 26 to move. Through the forward and reverse rotation of the forward and reverse motors 7, the moving block 22, the connecting plate 24, the U-shaped frame 25, and the brush 26 are driven to reciprocate back and forth to scrape off the impurities adsorbed on the filter screen 16. The scraped impurities fall into the receiving boxes 27 on both sides, and then the impurities in the receiving boxes 27 are regularly poured out.

[0060] The above embodiments are intended only to illustrate the technical solutions of the present application and are not intended to limit them. The present application is not limited to the precise structures described above and illustrated in the accompanying drawings, and it cannot be assumed that the specific implementation of the present application is limited to these descriptions. For those skilled in the art of the present application, any changes and modifications made without departing from the concept of the present application should be deemed to fall within the scope of protection of the present application.
