Embodiment

[0030] The environmental protection dismantling method of the gas cabinet used in the present invention first establishes a mechanical calculation model before the physical construction, and performs force calculation and analysis on the columns, hooks, and hanging points; through experiments, the special tools for the hooks, hanging plates, and cabinets are finally determined. The equipment used in the lifting and lowering of the roof; the composition of the residual chemicals on the cabinet wall is analyzed to determine the type of cleaning agent and the final environmental protection treatment index. And before the physical construction, the chemical residues accumulated in the gas tank must be treated to meet the emission requirements.

[0031] After the above-mentioned preparatory work is completed, the chemical residues accumulated in the gas cabinet should be treated first, and discharged after meeting the discharge requirements; then, after the cabinet top and the cabin...

Abstract

The invention discloses an environment-friendly demounting method of gas tank. The environment-friendly demounting method of gas tank comprises the steps of treating the chemical residues in the tank,separating the tank top in a high-altitude manner, declining the tank top, fixing the tank top, cleaning the chemical residues on the tank wall, cutting the wall plates and handling the wall plates and the like. The invention decreases the dismounting cost of the gas tank, improves the dismounting efficiency, realizes separation of working district and surrounding environment, ensures safety andenvironment protection in the dismounting process, avoids serious water system and environment pollution accidents occurring in the dismounting process, and does not influence the regular production of surrounding factories.

Description

technical field [0001] The invention relates to a dismantling method, in particular to an environmentally friendly dismantling method of a gas cabinet. Background technique [0002] The dismantling of large gas tanks, regardless of ensuring the safety of structural dismantling and the environmental protection of chemical residues, is very likely to cause disastrous consequences such as structural safety, personal safety, poisoning, fire, and environmental pollution. difficulty and risk. The environmental protection dismantling technology of large-scale gas cabinets is an important project in the construction of large-scale metallurgical industrial structure reconstruction projects. With the country's emphasis on industrial environmental protection and energy conservation, there are more and more super-large, Ultra-high gas cabinets appear. This type of equipment exceeds the hoisting capacity of general large-scale cranes, and there are risk factors such as difficulty in ins...
