Embodiment 1

[0034] Now adopt the method of the present invention to carry out the deoiling process before removing the industrial gas cabinet, and the deoiling process includes:

[0035] (a) Internal oil discharge of the oil channel system before oil cleaning;

[0036] When the oil is discharged, open the valve of the oil tank outside the cabinet, let the retained oil enter the piston oil tank in the cabinet, and empty the oil in the oil tank; after the nitrogen replacement at the bottom of the tank is qualified, the content of combustible gas and the animal survival test are passed. Finally, the operator enters the cabinet body from the upper hole of the piston, loosens the counterweight of the sliding plate traction device, increases the gap between the piston and the cabinet wall, and allows the sealing oil to flow from the piston oil tank to the tank bottom oil tank, and then further flows to the oil pump room oil tank. Then extract the sealing oil from the oil tank of the oil pump ro...

Abstract

The invention relates to a method for clearing oil stains on an industrial waste fuel gas cabinet. The method is used for cleaning internal structures, such as an oil passage system and an inner wall, of the waste fuel gas cabinet to be disassembled. In the process of disassembling the fuel gas cabinet, the use of fire for cutting easily causes fire and explosion safety risks. The method comprises: (a), draining an oil material in the oil passage system before cleaning the oil passage system; (b), injecting a prepared chemical cleaning agent through an original oil pumping system; (c), tapping, sprinkling and rinsing the inner wall of the fuel gas cabinet; (d), soaking, emulsifying, sprinkling and rinsing a piston oil tank, an oil tank bottom groove and a tank bottom; and (e), collecting and processing impurities and cleaning waste liquid. When the oil stains on the industrial waste fuel gas cabinet are cleared by the method provided by the invention, various oil stain impurities in the oil passage system of the fuel gas cabinet can be effectively cleaned, fire and explosion safety risks easily caused by fire cutting in the disassembling process are eliminated, waste oil pollution is reduced, and clean production is realized.

Description

technical field [0001] The invention relates to a method for cleaning oil stains, in particular to a method for cleaning oil stains in industrial waste gas cabinets. Background technique [0002] The gas cabinet is a device used to store industrial gas, and its basic features are high cabinet body, thin wall and large volume. In recent years, due to economic development and environmental protection construction requirements, the demolition and reconstruction projects of old-fashioned gas cabinets have increased year by year. The dismantling of the gas cabinet is highly professional and difficult to construct, and there are great safety hazards in the dismantling process. In particular, the treatment of sealing oil, graphite grease, oil-containing coating, anti-rust oil, cutting fluid and other oil stains in the crude oil pipeline system is one of the important processes before dismantling. [0003] Because hot cutting is likely to cause fire and explosion safety hazards du...
