[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1 As shown, a heat recovery device for a slurry bed reactor includes a downcomer 1, a liquid separation chamber 2 fixedly connected to the lower surface of the downcomer 1, a plurality of rising pipes 3 fixedly connected to the outer wall of the liquid separation chamber 2 and located outside the downcomer 1, a steam collecting chamber 4 fixedly connected to the upper surface of the plurality of rising pipes 3 and located above the downcomer 1, and two mounting components 5 fixedly installed on the outer wall of the plurality of rising pipes 3, the inner wall of the contributing part of the two mounting components 5 being fixedly connected to the outer wall of the downcomer 1 respectively.

[0020] First, boiler water is introduced into the downcomer 1. Then, under the action of the downcomer 1, the boiler water can enter the liquid distribution chamber 2. Next, it moves upward through several riser pipes 3. During the ascent, it absorbs external heat through the liquid distribution chamber 2, thereby forming water vapor and entering the steam collecting chamber 4. Finally, it is discharged through the exhaust pipe at the upper end of the steam collecting chamber 4. Under the action of two mounting components 5, several riser pipes 3 can be firmly fixed to the outside of the downcomer 1.

[0021] like Figure 2 As shown, the installation assembly 5 includes a fixing ring 51. The inner wall of the fixing ring 51 is fixedly connected to the outer wall of the downcomer 1. Several connecting plates 52 are fixedly connected to the outer wall of the fixing ring 51. Arc-shaped support plates 53 are fixedly connected to the side of each of the connecting plates 52 away from the fixing ring 51. Several arc-shaped connecting plates 54 are fixedly connected to the opposite sides of the arc-shaped support plates 53, and the arc-shaped connecting plates 54 are located outside the connecting plates 52. Arc-shaped limiting plate 1 55 is snapped onto the side of the left portion of the arc-shaped support plates 53 away from the fixing ring 51. Arc-shaped limiting plate 2 56 is snapped onto the side of the right portion of the arc-shaped support plates 53 away from the fixing ring 51. The opposite sides of the front and rear portions of arc-shaped limiting plate 1 55 and arc-shaped limiting plate 2 56 overlap each other. Through the action of several arc-shaped support plates 53, arc-shaped limiting plate one 55 and arc-shaped limiting plate two 56, several ascending pipes 3 can be installed and fixed on the outside of descending pipe 1. At the same time, since arc-shaped limiting plate one 55 and arc-shaped limiting plate two 56 are fixed on the left and right sides of the fixing ring 51 by fixing component 58 and plug rod 57, they can be easily installed, fixed and disassembled for maintenance during use.

[0022] Both the middle surfaces of the arc-shaped limiting plate 1 55 and the arc-shaped limiting plate 2 56 are fixedly connected with insert rods 57, and the outer walls of the two insert rods 57 are respectively inserted into the inner cavities of the two opposite arc-shaped connecting plates 54. Through the action of the two insert rods 57, the arc-shaped limiting plate 1 55 and the arc-shaped limiting plate 2 56 can be fixed on the left and right sides of the descending tube 1, thereby playing a connecting and supporting role.

[0023] like Figure 3 As shown, the front and rear sides of the arc-shaped limiting plate 55 are fixedly connected to the fixing block 551, and the front and rear sides of the arc-shaped limiting plate 56 are fixedly connected to the fixing block 561. The opposite surfaces of the two fixing blocks 551 and the two fixing blocks 561 overlap each other. The right side of the two fixing blocks 551 is fixedly connected to the fixing component 58. The fixing component 58 includes a threaded rod 581. The left side of the threaded rod 581 is fixedly connected to the right side of the fixing block 551. The outer wall of the threaded rod 581 is inserted into the inner cavity of the fixing block 561. The outer wall of the threaded rod 581 is threadedly connected to a nut 582, and the nut 582 is located on the right side of the fixing block 561. The threaded rod 581 and nut 582 enable the fixing block 551 and fixing block 561 to be connected and fixed, thereby cooperating with the insertion rod 57 to restrict and fix the arc-shaped limiting plate 55 and arc-shaped limiting plate 56. The operation is simple and the structure is simple.

[0024] like Figure 4 As shown, a washer 583 overlaps on the left side of the nut 582, the left side of the washer 583 overlaps with the right side of the fixing block 561, and the inner wall of the washer 583 is movably sleeved with the outer wall of the threaded rod 581. The washer 583 makes the nut 582 and the fixing block 561 more secure, thereby improving the fixing strength.

[0025] like Figure 5 As shown, a U-shaped insert rod 584 is inserted into the inner cavity of the threaded rod 581, which is away from the fixed block 551, and the right end of the U-shaped insert rod 584 is located to the right of the nut 582. The outer wall of the left part of the U-shaped insert rod 584 is inserted into the inner cavity of the fixed block 551. A limit block 585 is fixedly connected to the lower surface of the U-shaped insert rod 584, and the outer wall of the limit block 585 is slidably connected to the inner cavity of the fixed block 551. The limiting block 585 enables the U-shaped rod 584 to move vertically up and down, thus serving as a guide.

[0026] A spring 586 is fixedly connected to the upper surface of the limiting block 585. The inner wall of the spring 586 is movably sleeved with the outer wall of the left part of the U-shaped plug 584. The upper surface of the spring 586 is fixedly connected to the top of the inner cavity of the fixing block 551. The U-shaped insert 584 limits the nut 582, thereby further ensuring the stability after installation. At the same time, the spring 586 and the limiting block 585 allow the U-shaped insert 584 to move easily, making it easy to operate during installation or disassembly.

[0027] The working principle of this utility model is as follows: First, boiler water is introduced into the interior of the downcomer 1. Then, under the action of the downcomer 1, the boiler water can enter the interior of the separator 2. Next, it moves upward through the action of several riser pipes 3. During the ascent, it absorbs external heat through the separator 2, thereby forming water vapor and entering the interior of the steam collecting chamber 4. Finally, it is discharged through the exhaust pipe at the upper end of the steam collecting chamber 4. The riser pipes 3 can be installed and fixed on the outside of the downcomer 1 through the action of several arc-shaped support plates 53, arc-shaped limiting plate one 55 and arc-shaped limiting plate two 56. At the same time, the arc-shaped limiting plate one 55 and arc-shaped limiting plate two 56 are fixed on the left and right sides of the fixing ring 51 by the fixing component 58 and the insert rod 57. Then, the nut 582 is limited by the action of the U-shaped insert rod 584, thereby further ensuring the stability after installation.
