Description

Technical Field

[0001] This utility model belongs to the technical field of water and steam container structures for boilers, and particularly relates to a water and steam containment structure for a horizontal boiler. Background Technology

[0002] The horizontal arrangement of a horizontal boiler causes the flow direction of the steam-water mixture to be perpendicular to the direction of gravity, which reduces the natural separation efficiency and easily leads to steam carrying water droplets (high humidity) or water carrying steam (saturated water containing steam). Under low load conditions: when the flow rate decreases, the effect of gravity separation is further weakened, which may lead to incomplete separation.

[0003] This shows that existing horizontal boilers have issues with incomplete separation of steam and water in their water and steam containers. Summary of the Invention

[0004] The purpose of this utility model embodiment is to provide a water and steam containment structure for a horizontal boiler, aiming to solve the problem of incomplete separation of steam and water in the water and steam containers of existing horizontal boilers.

[0005] The present invention is implemented as follows:

[0006] A water and steam containment structure for a horizontal boiler includes a D-shaped left membrane wall, a V-shaped middle membrane wall, and a V-shaped right membrane wall. The left, middle, and right membrane walls are connected at the top and converge in an upper manifold. The left, middle, and right membrane walls are connected at the bottom and converge in a lower manifold. A water inlet pipe is provided at the bottom of the lower manifold. Several steam pipes are provided at the top of the upper manifold, and the top of each steam pipe is connected to a steam collecting chamber. Several external flanges are provided at the top of the steam collecting chamber. A steam-water separator is provided in the steam pipes to separate steam and water. At the connection between the space of the upper manifold and the space of the steam pipes, the diameter of the steam passage becomes smaller to increase the steam flow rate.

[0007] Furthermore, the steam-water separator is a spiral gas pipe located at the bottom of the steam pipe. The spiral gas pipe has a spiral guide groove on the inner side of its wall. When steam passes through the spiral gas pipe, it forms a spiral airflow under the guidance of the spiral guide groove.

[0008] Furthermore, the steam-water separator is a spiral blade installed at the bottom of the steam pipe. When steam passes through the spiral blade, it forms a spiral airflow under the guidance of the spiral blade.

[0009] Furthermore, the spiral blades are fixed to the outer side of the conical surface of the conical disk, and at least two spiral blades are provided and evenly fixed to the outer side of the conical surface of the conical disk.

[0010] Furthermore, the small end of the conical disk is located on the side closer to the upper manifold.

[0011] Furthermore, the central axis of the conical disk is provided with a rotating shaft, the top of which is rotatably connected to the center of the upper support ring, and the bottom of which is rotatably connected to the center of the lower support ring.

[0012] Furthermore, the centers of the upper support ring 1 and the lower support ring are connected to the circumference of the upper support ring and the lower support ring by stiffening plates, and the empty part forms a vent hole for steam to pass through.

[0013] Furthermore, the circumferences of the support ring and the lower support ring are fixed to the interior of the steam pipe.

[0014] The positive effects of this utility model are: by connecting the D-shaped left membrane wall, the V-shaped middle membrane wall, and the D-shaped right membrane wall, as well as the lower and upper manifolds, a water and steam containment structure for a horizontal boiler is formed. The top of the steam pipes is connected to the steam collection manifold. A steam-water separator is provided in the steam pipes to separate the steam and water, which is more conducive to the drying of steam and the recirculation of water to reheat and form steam.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] like Figures 1 to 5 The diagram shows a structural design of a horizontal boiler for storing water and steam according to an embodiment of this utility model. The storage structure includes a D-shaped left membrane wall 1, a V-shaped middle membrane wall 2, and a D-shaped right membrane wall 5. The left membrane wall 1, middle membrane wall 2, and right membrane wall 5 are connected at the top and converge in an upper manifold 7. The left membrane wall 1, middle membrane wall 2, and right membrane wall 5 are connected at the bottom and converge in a lower manifold 4. A water inlet pipe 3 is provided at the bottom of the lower manifold 4. Several steam pipes 6 are provided at the top of the upper manifold 7. The top of each steam pipe 6 is connected to a steam collection manifold 9. Several external flanges are provided at the top of the steam collection manifold 9. A steam-water separator is provided in the steam pipe 6 to separate steam and water. At the connection between the space of the upper manifold and the space of the steam pipe, the diameter of the steam passage becomes smaller to increase the steam flow rate.

[0025] In this embodiment of the utility model, the D-shaped left membrane wall 1, the V-shaped middle membrane wall 2, and the D-shaped right membrane wall 5, as well as the lower manifold 4 and the upper manifold 7 are interconnected to form a water and steam containment structure for a horizontal boiler. The top of the steam pipe 6 is connected to the steam collection manifold 9. A steam-water separator is provided in the steam pipe 6 to separate the steam and water, which is more conducive to the drying of steam and the return of water, and reheating to form steam.

[0026] Specifically, such as Figures 1 to 5As shown, a water and steam containment structure for a horizontal boiler includes a D-shaped left membrane wall 1, a V-shaped middle membrane wall 2, and a D-shaped right membrane wall 5. The left membrane wall 1, middle membrane wall 2, and right membrane wall 5 are connected at the top and converge in an upper manifold 7; the left membrane wall 1, middle membrane wall 2, and right membrane wall 5 are connected at the bottom and converge in a lower manifold 4; a water inlet pipe 3 is provided at the bottom of the lower manifold 4; several steam pipes 6 are provided at the top of the upper manifold 7, and the top of each steam pipe 6 is connected to a steam collection manifold 9. Several external flanges are provided at the top of the steam collection manifold 9. A steam-water separator is provided in the steam pipe 6 to separate steam and water. At the connection between the space of the upper manifold and the space of the steam pipe, the diameter of the steam passage becomes smaller to increase the steam flow rate.

[0027] The steam-water separator is a spiral gas pipe located at the bottom of the steam pipe. The spiral gas pipe has a spiral guide groove on the inner side of the pipe wall. When steam passes through the spiral gas pipe, it forms a spiral airflow under the guidance of the spiral guide groove. Under the action of centrifugal force, water is thrown from the steam to the inner wall surface of the steam pipe, and then flows back to the upper manifold 7, as well as the D-shaped left membrane wall 1, the V-shaped middle membrane wall 2, and the D-shaped right membrane wall 5 along the inner wall surface of the steam pipe.

[0028] The steam-water separator is a spiral blade 11 installed at the bottom of the steam pipe. When steam passes through the spiral blade 11, a spiral airflow is formed under the guidance of the spiral blade 11. Under the action of centrifugal force, water is thrown from the steam to the inner wall surface of the steam pipe, and then flows back to the upper manifold 7, as well as the D-shaped left membrane wall 1, the V-shaped middle membrane wall 2, and the D-shaped right membrane wall 5 along the inner wall surface of the steam pipe.

[0029] The spiral blade 11 is fixed to the outer side of the conical surface of the conical disk 14. There are at least two spiral blades 11, which are evenly fixed to the outer side of the conical surface of the conical disk 14.

[0030] The small end of the conical disk 14 is located on the side closer to the upper manifold 7, which is more conducive to generating a spiral airflow and to the spiral airflow passing through the inner wall surface of the steam pipe. This promotes water to be thrown from the steam onto the inner wall surface of the steam pipe and then flows back to the upper manifold 7, as well as the D-shaped left membrane wall 1, the V-shaped middle membrane wall 2, and the D-shaped right membrane wall 5.

[0031] The conical disk 14 has a central shaft 13. The top of the shaft 13 is rotatably connected to the center of the upper support ring 15, and the bottom of the shaft 13 is rotatably connected to the center of the lower support ring 12. The centers of the upper support ring 15 and the lower support ring 12 are connected to the circumference of the upper support ring 15 and the lower support ring 12 through the stiffener 17. The empty part forms a steam channel, that is, a vent hole 16.

[0032] The circumferences of the upper support ring 15 and the lower support ring 12 are fixed to the inside of the steam pipe 6.

[0033] The foregoing has broadly outlined some aspects and features of the various embodiments and should be interpreted as merely illustrative of potential applications. Other beneficial results can be obtained by applying the disclosed information in different ways or by combining aspects of the disclosed embodiments. Further aspects and a more complete understanding can be obtained based on the detailed description of exemplary embodiments with reference to the accompanying drawings, within the scope defined by the claims.

Of course, the above description is not intended to limit the present invention, nor is the present invention limited to the examples described above. Any changes, modifications, additions, reductions, or substitutions made by those skilled in the art within the scope of the present invention are also within the protection scope of the present invention.
