Description

Technical Field

[0001] The utility model relates to the technical field of galvanized sheet smoke exhaust, in particular to a galvanized sheet smoke exhaust air duct. Background Art

[0002] Air ducts, as a piping system specifically used for air delivery and distribution, are usually divided into two types: composite air ducts and inorganic air ducts. In the application of fire smoke exhaust, air ducts play a vital role, which can effectively transport smoke to the outside, realize smoke exhaust treatment, and ensure fire safety.

[0003] However, after long-term use, the inner wall of the air duct is often corroded by sulfur dioxide in the flue gas. This long-term corrosion may not only cause damage to the air duct, but also pose a potential threat to the normal operation of the system. Therefore, once the air duct is found to be damaged, it needs to be replaced in time to ensure the safety and stability of the system.

[0004] At present, most of the air ducts on the market adopt a single-layer structure, which increases the complexity and cost of replacement to a certain extent. When a damaged air duct needs to be replaced, it is often necessary to replace the entire air duct, which is undoubtedly a waste of resources. At the same time, the process of replacing the air duct also requires disassembly and assembly, which is not only time-consuming and labor-intensive, but may also affect the normal operation of the system.

[0005] Therefore, it is necessary for us to optimize the design of the existing air duct structure to improve its durability and maintainability, reduce the frequency and cost of replacement, and ensure the continuous and stable operation of the system. For the above problems, there may already be technical means to solve them in the existing technology, but this case wants to provide an alternative or replacement technical solution.

This design is not only easy to install and disassemble, but also helps to reduce maintenance costs and improve maintenance efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
