Abstract

The invention relates to a method for dismantling a dry-type Man-type gas cabinet, which includes steps such as air replacement, erection of scaffolding, emulsification and soaking of dirty oil and impurities with a chemical cleaner, dismantling of the top system of the cabinet and lowering of the bottom, dismantling of the main structure, lifting, cleaning waste liquid treatment, etc. . The demolition method reduces the risk of dismantling inflammable and explosive structures, reduces the pollution to surrounding areas and the environment, and has low demolition costs, and is especially suitable for demolition operations in a working environment where the work site is narrow and it is difficult to stack large components.

Description

technical field [0001] The invention relates to a method for dismantling a gas cabinet, in particular to a method for dismantling a dry Mann-type gas cabinet. Background technique [0002] In recent years, due to economic development and environmental protection construction requirements, dry-type Mann-type gas cabinets have been gradually replaced by safer gas cabinets such as POC due to the shortcomings of low gas storage pressure and unsatisfactory sealing effect. The number of demolition works for dry-type Mann-type gas cabinets is increasing year by year. The demolition of gas cabinets is highly specialized and difficult to construct, and has high requirements for construction technology and safety protection technology during the construction process. [0003] The traditional method of dismantling the gas cabinet is to lift the piston of the gas cabinet itself to the top of the cabinet with air, and then use the piston as the operating platform for the dismantling ope...
