Description

Technical Field

[0001] This utility model belongs to the field of waste incinerator technology, and more specifically, it relates to a membrane wall screen structure for waste incinerators. Background Technology

[0002] STP-type waste incinerators are divided into different boiler models such as STP30, STP40, and STP50, depending on the equipment model. The width of each STP boiler varies with the model. The combustion chamber roof and the membrane wall (intermediate partition wall) are connected via tees. Finally, the different components of the membrane wall are welded together to form a unified membrane wall structure. However, in existing technologies, different components need to be fabricated into segmented structures, followed by on-site welding of tees and individual components, resulting in a large workload and low efficiency.

[0003] Existing technology includes a paper titled "A Membrane Water-Cooled Wall for a Waste Incinerator and Its Corrosion Prevention Method," with publication number CN114135877A. This technology discloses a membrane water-cooled wall for a waste incinerator and its corrosion prevention method, comprising a waste incinerator and a membrane water-cooled wall. The membrane water-cooled wall includes steel plate walls and welded steel pipes arranged neatly. A chemical corrosion prevention structure is also provided at the high-temperature hot water or steam outlet of the welded steel pipes. The chemical corrosion prevention structure includes an iron ion detection and sampling structure and a corrosion substitute supply structure. The corrosion substitute supply structure is an automatic compensation feeding mechanism for magnesium-zinc rod loss, including magnesium-zinc rods, an automatic limit feeding device, a sealing system, and an alarm module. This invention has a simple structure, is easy to manufacture, has low cost, and is reliable for construction, modification, and installation. It can provide very effective protection, prevent or significantly slow down its corrosion effect, and greatly extend the service life of the membrane water-cooled wall. It is flexible in use and suitable for the construction of new membrane water-cooled walls and the renovation of aging membrane water-cooled walls. However, this technology does not address the technical issues and solutions of this application. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a membrane wall structure for waste incinerators that is simple in structure, can reduce labor intensity and improve assembly efficiency, in order to address the shortcomings of the existing technology.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model is a membrane wall screen structure for a waste incinerator. The membrane wall screen includes multiple pipes, which are welded together. Each pipe includes a first pipe assembly, a second pipe assembly, a third pipe assembly, a first tee, and a second tee. The first pipe assembly and the second pipe assembly are connected by the first tee, and the second pipe assembly and the third pipe assembly are connected by the second tee.

[0007] The pipe fitting is configured to be made of the original pipe fitting material.

[0008] The length of the raw material for the pipe fittings is equal to the sum of the lengths of the first pipe fitting assembly, the second pipe fitting assembly, the third pipe fitting assembly, the first tee, and the second tee.

[0009] The raw materials for the pipe fittings are cut and welded at the first tee and the second tee locations, respectively.

[0010] Multiple pipes form a membrane wall screen.

[0011] Both the first tee and the second tee are structures made of steel pipe fittings.

[0012] The first tee includes a body section and a bend section. The first opening of the body section is connected to the first pipe fitting assembly, the second opening of the body section is connected to the second pipe fitting assembly, one end of the bend section is connected to the body section, and the other end of the bend section is connected to the combustion chamber roof.

[0013] The second tee includes a body section and a bend section. The first opening of the body section connects to the second pipe fitting assembly, the second opening of the body section connects to the third pipe fitting, one end of the bend section connects to the body section, and the other end of the bend section connects to the combustion chamber roof.

[0014] The multiple pipe fittings are arranged in parallel and are located on the same plane.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] The membrane wall screen structure for waste incinerators described in this utility model employs a novel approach to its fabrication. First, raw pipe materials are fabricated according to the required pipe diameter and length. These raw materials are then welded together, with multiple raw pipe materials arranged in parallel on the same plane to form the membrane wall screen material. The membrane wall screen material is then placed on the construction site, and each raw pipe material is processed individually. Specifically, for each raw pipe material requiring a tee (or T-junction), openings are cut at the first and second tee locations, with the opening length equal to the tee length. The first and second tee are then welded together. This process of cutting and welding tee sections onto each raw pipe material results in multiple pipe components, each comprising a first component assembly, a second component assembly, a third component assembly, a first tee, and a second tee. Next, each first tee and each second tee are welded to connect to the combustion chamber ceiling, realizing the on-site assembly of the membrane wall panel and the connection between the membrane wall panel and the combustion chamber ceiling. The membrane wall panel is used for cooling water passage to achieve cooling. The structure of this utility model not only ensures the overall quality of the membrane wall panel, but also reduces the assembly time between the membrane wall panel and the tee. After the improvement, the assembly of a single membrane wall panel (intermediate partition) of the same model and size, which originally required 6 people and 6 days to complete, can now be completed by 2 people in 4 days. This not only ensures the performance and quality requirements of the product, but also improves production efficiency and reduces production costs. Attached Figure Description

[0023] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0024] As attached Figure 1 -Appendix Figure 4 As shown, this utility model is a membrane wall screen structure for a waste incinerator. The membrane wall screen includes multiple pipes 6, which are welded together. Each pipe 6 includes a first pipe assembly 1, a second pipe assembly 2, a third pipe assembly 3, a first tee 4, and a second tee 5. The first tee 4 connects the first pipe assembly 1 and the second pipe assembly 2, and the second tee 5 connects the second pipe assembly 2 and the third pipe assembly 3. This structure addresses the shortcomings of existing technologies by proposing an improved technical solution. The pipes 6 are constructed from pipe material 7. A novel approach is adopted in the fabrication of the membrane wall screen structure for the waste incinerator. First, the pipe material is fabricated according to the required pipe diameter and length. Then, the pipe material is welded together, with multiple pipe materials arranged in parallel on the same plane to form the membrane wall screen material. The membrane wall screen material is then placed on the construction site, and each pipe material is processed separately. This involves setting a tee position for each pipe fitting material. Specifically, openings 10 are cut at the first tee placement position 8 and the second tee placement position 9 of each pipe fitting material 7, with the opening length equal to the tee length. Then, the first tee 4 and the second tee 5 are welded on. This process of cutting and welding tees is repeated for each pipe fitting material. This results in multiple pipe fittings, each including a first pipe fitting assembly 1, a second pipe fitting assembly 2, a third pipe fitting assembly 3, a first tee 4, and a second tee 5. Each first tee and each second tee are then welded to connect to the combustion chamber ceiling, achieving on-site assembly of the membrane wall screen and connection between the membrane wall screen and the combustion chamber ceiling. The membrane wall screen allows cooling water to pass through, achieving cooling. This invention's structure not only ensures the overall quality of the membrane wall screen but also reduces the assembly time between the membrane wall screen and the tees. After practical demonstration, the improved membrane wall screen (intermediate partition) of the same model and size, which previously required 6 people and 6 days to assemble a single unit, has been improved. The process improvement can be completed by two people in four days; it ensures product performance and quality requirements while improving production efficiency and reducing production costs. The membrane wall panel structure for the waste incinerator described in this invention is simple in structure, reduces labor intensity, and improves assembly efficiency.

[0025] The length of the pipe fitting material 7 is equal to the sum of the lengths of the first pipe fitting assembly 1, the second pipe fitting assembly 2, the third pipe fitting assembly 3, the first tee 4, and the second tee 5. In the above structure, the pipe fitting material 7 is made of steel pipe, and multiple pipe fitting materials are welded together to form the membrane wall screen material.

[0026] The raw material 7 of the pipe fitting is cut with openings 10 at the first tee arrangement position 8 and the second tee arrangement position 9, and the first tee 4 and the second tee 5 are welded on. In the above structure, each raw material of the pipe fitting is cut, the tee is welded on, and the corresponding pipe fitting is processed into a membrane wall screen 14.

[0027] Both the first tee 4 and the second tee 5 are structures made of steel pipe fittings. The first tee 4 and the second tee 5 are pre-machined and welded to the cut opening positions.

[0028] The first tee 4 includes a body section 11 and a bent section 12. The first opening of the body section 11 connects to the first pipe assembly 1, and the second opening of the body section 11 connects to the second pipe assembly 2. One end of the bent section 12 connects to the body section 11, and the other end of the bent section 12 connects to the combustion chamber roof 13. In this structure, the first tee 4 of each pipe connects to the combustion chamber roof 13, realizing the connection between the combustion chamber roof 13 of the incinerator and the membrane wall (intermediate partition wall) through the first tee.

[0029] The second tee 5 includes a body section 11 and a bending section 12. The first opening of the body section 11 connects to the second pipe fitting assembly 2, and the second opening of the body section 11 connects to the third pipe fitting 3. One end of the bending section 12 connects to the body section 11, and the other end of the bending section 12 connects to the combustion chamber roof 13. In this structure, the second tee 5 of each pipe fitting connects to the combustion chamber roof 13, realizing the connection between the combustion chamber roof of the incinerator and the membrane wall (intermediate partition wall) through the second tee.

[0030] The multiple pipes 6 are arranged in parallel and located on the same plane. This structure forms a planar membrane wall 14, which facilitates connection to the combustion chamber ceiling 13.

[0031] The membrane wall screen structure for a waste incinerator described in this utility model employs a novel approach in its construction. First, raw pipe materials are fabricated according to the required pipe diameter and length. These raw materials are then welded together, with multiple raw pipe materials arranged in parallel on the same plane to form the membrane wall screen material. The membrane wall screen material is then placed on the construction site, and each raw pipe material is processed individually. Specifically, for each raw pipe material requiring a tee, openings 10 are cut at the first tee placement position 8 and the second tee placement position 9 of each raw pipe material 7. The length of the opening is equal to the length of the tee. Then, the first tee 4 and the second tee 5 are welded together. This process of cutting and welding tees is repeated for each raw pipe material. This results in multiple pipe components, each including a first pipe component assembly 1, a second pipe component assembly 2, a third pipe component assembly 3, a first tee 4, and a second tee 5. Then, each first tee and each second tee are welded to the combustion chamber ceiling, realizing the on-site assembly of the membrane wall panel and the connection between the membrane wall panel and the combustion chamber ceiling. The membrane wall panel is used for cooling water passage to achieve cooling. The structure of this utility model not only ensures the overall quality of the membrane wall panel, but also reduces the assembly time between the membrane wall panel and the tee. After actual demonstration, after improvement, the assembly of a single membrane wall panel (intermediate partition) of the same model and size, which originally required 6 people and 6 days to complete, can now be completed by 2 people in 4 days after the process improvement; this ensures the performance and quality requirements of the product, improves production efficiency, and reduces production costs.
