Description

Technical Field

[0001] This utility model relates to the field of construction technology of gas turbine waste heat boilers, and in particular to a sealing device for the corner connection of the gas turbine waste heat boiler guard plate. Background Technology

[0002] Gas turbine waste heat boilers utilize the residual heat from waste gas, waste materials, or waste liquids generated in various industrial processes, as well as the heat produced by the combustion of combustible substances, to heat water to a certain temperature. To ensure the full utilization of flue gas heat, the sealing of steel frame panel joints and corners is crucial. Therefore, when installing internal insulation at steel frame panel joints and corners on-site, the insulation material must be filled completely. The insulation material should be staggered and compacted, and the overlap of the inner lining panels should align with the flue gas flow direction, ensuring free expansion.

[0003] Different designs and installation methods result in varying degrees of difficulty in on-site construction. In the past, when connecting the steel frame guard plate joints and corners of gas turbines, the inner lining plate was often installed inside the guard plate, which made on-site installation troublesome and difficult to adjust. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model designs a sealing device for the corner connection of the gas turbine waste heat boiler guard plate, so as to facilitate installation, sealing, adjustment and disassembly, and prevent the heat of the flue gas from being lost too quickly when passing through the connection, thus avoiding energy waste.

[0005] The present invention adopts the following technical solution:

[0006] A sealing device for the corner connection of a gas turbine waste heat boiler liner includes a corner sealing steel plate, an inner lining plate, and insulation cotton. The corner sealing steel plate is installed on the outside of the gas turbine waste heat boiler liner and seals against the outside of the liner. The inner lining plate is installed on the outside of the inner steel plate of the gas turbine waste heat boiler liner. The insulation cotton is made of multiple layers of longitudinally and diagonally arranged cotton compressed together, with each layer of cotton overlapping and compacted.

[0007] Preferably, the thickness of the corner sealing steel plate is 6 mm.

[0008] Preferably, the insulation cotton is used in conjunction with high-temperature adhesive to ensure that it is tightly filled between the corner sealing steel plate, the inner lining plate, and the protective plate.

[0009] Preferably, the insulation cotton is made of four layers of 50mm thick and two layers of 28mm thick super cotton compressed together.

[0010] Preferably, the thickness of the inner lining plate is 2.5 mm.

[0011] Preferably, the corner sealing steel plate is welded and sealed to the outer steel plate of the protective plate.

[0012] Preferably, the inner lining plate is plug-welded to the inner steel plate of the protective plate.

[0013] The beneficial effects of this utility model are: This utility model designs a sealing device for the corner connection of the gas turbine waste heat boiler guard plate; the use of this sealing device can reduce the loss of flue gas heat, and it is convenient to install, adjust and disassemble.

[0015] In the diagram: 1. Corner sealing steel plate, 2. Insulation cotton, 3. Inner lining plate, 4. Protective plate. Detailed Implementation

[0016] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0017] Example: Figure 1 As shown, a sealing device for the corner connection of a gas turbine waste heat boiler liner includes a corner sealing steel plate 1, insulation cotton 2, and an inner lining plate 3. The corner sealing steel plate 1 is a 6mm thick steel plate. The insulation cotton 2 is composed of four layers of 50mm thick and two layers of 28mm thick super cotton, compressed and overlapped in a staggered manner, and tightly packed. The insulation cotton 2 needs to be used with high-temperature mortar to ensure a tight filling. The inner lining plate 2 is a 2.5mm thick steel plate. The corner sealing steel plate is welded to the outer steel plate of the liner 4 for sealing. The inner lining plate is plug-welded to the inner steel plate of the liner.

[0018] During on-site construction, the inner lining plate 3 is installed on the outside of the inner steel plate of the protective plate and fastened with bolts, overlapping in the direction of flue gas. The insulation cotton 2 at the corners of the protective plate is compressed on-site with 4 layers of 50mm thick and 2 layers of 28mm thick super cotton, overlapping in a staggered manner, and then filled with high-temperature mortar and pressed tightly into the corners of the protective plate. After the insulation cotton is filled and pressed, the corners of the outer side of the protective plate are sealed with steel plate 1.

[0019] The above-described embodiments are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
