Description

Technical Field

[0001] This utility model belongs to the field of dry quenching equipment, specifically relating to a support structure for a dry quenching boiler tube system. Background Technology

[0002] Dry quenching coke boilers, with their advantages of energy saving, environmental protection, and improved resource utilization, have been widely used in industries such as steel and chemicals. With the increasing prominence of the global energy crisis and environmental issues, the promotion and application of dry quenching technology will become even more significant. In the future, with continuous technological advancements and innovation, dry quenching coke boilers are expected to leverage their unique advantages in even more fields.

[0003] A dry quenching boiler is a pressurized heating device that absorbs heat from circulating gas and then transfers that heat to the boiler feedwater to produce steam with rated parameters and quality, which is then delivered to heat users. The dry quenching boiler is an important component of the dry quenching system and one of the key technologies.

[0004] Due to design flaws, during long-term operation, dry-quenched coke boilers experience deformation of the boiler tube system caused by vibration and corrosion. This deformation leads to uneven heating, expansion, and contraction, resulting in ruptures and leaks. The hazards vary depending on the location, timing, and amount of the leak; leaks can cause production shutdowns, equipment damage, and in severe cases, boiler explosions, causing personal injury and property damage. Therefore, preventing boiler tube deformation-induced leaks and ensuring continuous and stable production is a pressing issue that needs to be addressed.

[0005] Existing technology, CN2018208056668, discloses a boiler economizer piping support structure and its arrangement. This structure includes an economizer frame beam, an economizer guard plate frame fixed above the economizer frame beam, and an economizer piping system located within the economizer guard plate frame. The economizer piping system is fixed to an economizer ventilation beam, with both ends of the ventilation beam passing through the economizer guard plate frame. The bottom of the ventilation beam is supported on the economizer frame beam, and a lubrication device is provided between the bottom of the ventilation beam and the economizer frame beam. This support structure is relatively complex and inconvenient to install. Summary of the Invention

[0006] The purpose of this utility model is to provide a support structure for dry quenching coke boiler tube systems that is simple in structure, easy to install, and has reasonable stress distribution.

[0007] A pipe system support structure for a dry quenching coke boiler is provided. The support structure consists of several support units arranged on the boiler pipe system along the direction of flue gas travel in the boiler. Each support unit includes two triangular outer support frames, an intermediate support frame set at the three corners of the triangular outer support frames, and a limiting groove set at the top of the triangular outer support frames. The three corners of the triangular outer support frames are fixedly connected to the intermediate support frames, and the intermediate support frames are fixedly connected to the limiting grooves. The boiler tubes are supported by the limiting grooves.

[0008] The aforementioned triangular outer support frame consists of three support rods or three strip plates.

[0009] The aforementioned intermediate support frame is a rectangular plate or a rectangular curved plate.

[0010] The aforementioned limiting groove is a semi-circular tube, with the inner diameter of the semi-circular tube being slightly larger than the outer diameter of the boiler tube.

[0011] The aforementioned support units are arranged at intervals of 800-1500mm on the boiler piping system, and are staggered.

[0012] The aforementioned support unit is movably connected to the boiler tube, and its position can be adjusted along the length of the boiler tube.

[0013] Compared with existing technologies, this utility model has the following advantages:

[0014] This utility model improves the support structure of the dry quenching boiler tube system, realizing the movable connection between the boiler and the furnace tubes, and effectively fixing the dry quenching boiler tube bundle. The design is novel, the structure is simple, the processing is convenient, and the installation is easy. It solves the shortcomings of the existing technology that cause cracking and leakage due to vibration fatigue, uneven heating, and uneven expansion of the boiler tube system. It not only extends the service life of the boiler, but also helps to stabilize the production of the dry quenching unit. Attached Figure Description

The support structure consists of several support units arranged on the boiler pipe system along the direction of flue gas travel in the boiler. Each support unit includes two triangular outer support frames 2, an intermediate support frame 1 set at the three corners of the triangular outer support frames, and a limiting groove 3 set at the top of the triangular outer support frames. The three corners of the triangular outer support frames 2 are fixedly connected to the intermediate support frame 1, the intermediate support frame 1 is fixedly connected to the limiting groove 3, and the limiting groove 3 movably supports the pipe coefficient.

[0020] The triangular outer support frame 2 can be composed of three support rods or three strip plates, such as by welding.

[0021] The intermediate support frame 1 can be a rectangular plate or a rectangular curved plate.

[0022] The limiting groove 3 is a semi-circular tube, and the inner diameter of the semi-circular tube is slightly larger than the outer diameter of the boiler tube.
