Description

Technical Field

[0001] The present invention relates to the technical field of boiler equipment, and in particular to a self-hanging mixing header and a layout method thereof. Background Art

[0002] The boiler mixing header is designed to mix the medium in the tubes, making the tube wall temperature more uniform and the boiler operation more stable. Currently, the mixing header structures in the existing technology all require an independent hanging system, namely spring hanging or rigid hanging. Spring hanging is relatively expensive, and rigid hanging will add additional load to the loose tubes due to expansion differences, thereby posing a greater risk in later operation. Both have disadvantages to varying degrees. Summary of the Invention

[0003] The purpose of the present invention is to provide a self-hanging mixing header and its arrangement method, which can meet the hanging function of the header through its own structure, eliminate the original hanging structure, save costs, and reduce safety hazards in the later operation of the boiler.

[0004] The above purpose is achieved through the following technical solutions:

[0005] A self-hanging mixing header, comprising: a header, the top of the header being connected to an inlet pipe, the two sides of the header being respectively connected to an outlet pipe A and an outlet pipe B, the oblique side of the header being connected to one end of a hanging pipe, the other end of the hanging pipe being connected to the middle end of a tee, the two end interfaces of the tee being respectively connected to the two sections of the interfaces of the outlet pipe A, the inlet pipe, the outlet pipe A and the outlet pipe B being all loose pipes, and merging into a pipe wall at the plane of the pipe wall, the hanging pipe and the outlet pipe A close to the side of the pipe wall forming a triangular structure, and the hanging pipes being arranged at intervals on the header.

[0006] A method for arranging a self-suspended mixing header comprises the following steps:

[0007] First, the header is suspended outside the pipe wall. The medium enters from the top of the header through the inlet pipe, is mixed inside the header and then flows out from the outlet pipes on both sides. The inlet pipe, outlet pipe A and outlet pipe B connected to the mixing header are all loose pipes and merge into the pipe wall at the pipe wall plane.

[0008] One end of the hanging pipe is connected to the side of the header, and the other end of the hanging pipe is connected to the tee on the outlet pipe A, which plays a role in hanging the header. Together with the outlet pipe A close to the pipe wall, a stable triangular system is formed. The inlet pipe, the outlet pipe A, the outlet pipe B, and the header form a small chamber outside the pipe wall. The hanging pipe is completely inside the small chamber. The outside of the small chamber can be covered with insulation as a whole, without any external structure, and the overall appearance is beautiful.

[0009] The hanging pipes are arranged at intervals on the header to disperse the load of the header. The number of hanging pipes can be determined by strength calculation of the hanging pipes. The upper and lower pipe walls of the header are either a lower spiral pipe wall and an upper vertical pipe wall, or both upper and lower vertical pipe walls. The difference lies in the position of the openings on the header and the relative number of inlet and outlet pipes.

[0010] Beneficial effects:

[0011] 1. The present invention is a method for arranging a self-hanging hybrid header. This structure provides a header that can satisfy the hanging function by itself, eliminates the original hanging structure, saves costs, reduces safety hazards in later operation, and effectively ensures the safe and reliable operation of the equipment.

[0012] 2. The present invention adopts a new structure to realize the hanging function of the mixing header. The specific structure is that the header is suspended outside the pipe wall. The medium enters from the top of the header through the inlet pipe, is mixed in the header and flows out from the outlet pipes on both sides. The inlet pipe and the outlet pipe connecting the mixing header are both loose pipes, which merge into the pipe wall at the plane of the pipe wall. One end of the hanging pipe is connected to the side of the header, and the other end is connected to the tee on the outlet pipe, which plays a hanging role for the header. Together with the outlet pipe close to the side of the pipe wall, a stable triangular system is formed, so that the header itself meets the hanging conditions and no additional hanging structure is required.

[0013] 3. The inlet pipe, outlet pipe A, outlet pipe B header, etc. of the present invention form a small chamber outside the pipe wall, and the hanging pipe is completely in the small chamber, which is convenient for on-site installation and maintenance. The outside of the small chamber can be covered with insulation as a whole without any external structure, which can make the overall structure simple and beautiful.

[0014] 4. The form of the header of the present invention is not limited to the form of the upper and lower pipe walls of the header. It can be a lower spiral pipe wall and an upper vertical pipe wall, or both the upper and lower vertical pipe walls. The difference lies in the position of the openings on the header and the relative number of inlet and outlet pipes, which has the advantages of strong flexibility.

[0015] 5. The hanging pipes of the present invention are arranged at intervals on the header to disperse the header load. The number of hanging pipes can be determined by strength calculation. This allows the header itself to meet the hanging function while reducing costs and ensuring stable operation of the boiler. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Example 1:

[0020] A self-hanging mixing header, comprising: a header 2, the top of the header being connected to the inlet pipe 5, the two sides of the header being connected to the outlet pipe A1 and the outlet pipe B6 respectively, the oblique side of the header being connected to one end of the hanging pipe 3, the other end of the hanging pipe being connected to the middle end of the tee 4, the two end interfaces of the tee being connected to the two sections of the interfaces of the outlet pipe A respectively, the inlet pipe, the outlet pipe A and the outlet pipe B being all loose pipes, and merging into a pipe wall at the plane of the pipe wall, the hanging pipe and the outlet pipe A close to the side of the pipe wall forming a triangular structure, and the hanging pipes being arranged at intervals on the header.

[0021] Example 2:

[0022] According to the arrangement method of the self-suspended mixing header described in Example 1, the method includes the following steps:

[0023] First, the header is suspended outside the pipe wall. The medium enters from the top of the header through the inlet pipe, is mixed inside the header and then flows out from the outlet pipes on both sides. The inlet pipe, outlet pipe A and outlet pipe B connected to the mixing header are all loose pipes and merge into the pipe wall at the pipe wall plane.

[0024] One end of the hanging pipe is connected to the side of the header, and the other end of the hanging pipe is connected to the tee on the outlet pipe A, which plays a role in hanging the header. Together with the outlet pipe A close to the pipe wall, a stable triangular system is formed. The inlet pipe, the outlet pipe A, the outlet pipe B, and the header form a small chamber outside the pipe wall. The hanging pipe is completely in the small chamber, which is convenient for on-site installation and maintenance. The outside of the small chamber can be covered with insulation as a whole, without any external structure, and the overall appearance is beautiful.

[0025] The hanging pipes are arranged at intervals on the header to disperse the header load. The number of hanging pipes can be determined by strength calculation of the hanging pipes. This allows the header itself to meet the hanging function, reduce costs, and ensure stable operation of the boiler.

[0026] The pipe walls of the header are either spiral pipe walls at the bottom and vertical pipe walls at the top, or vertical pipe walls at the top and bottom. The difference lies in the position of the openings on the header and the number of inlet and outlet pipes.

[0027] This application solves the problem that the traditional intermediate header does not have its own hanging ability and requires an external hanging structure to complete it. There are two types of hanging forms: spring hangers or rigid hangers. The spring hangers are relatively expensive, and the rigid hangers will add additional external loads to the header pipe joints due to expansion, causing cracks in the pipe joints. The purpose of this application is to eliminate the hanging restrictions and meet the hanging function by itself.

[0028] Compared with a spring hanger, the present application reduces costs and can effectively improve structural safety performance compared with a rigid beam hanger.
