Method and system for cleaning lubricating oil in a compression unit type oil injection

摘要

Method and system for cleaning lubricating oil in a compression unit type oil injection, the present invention aims, when compressed by a screw compressor gas injection type of base oil of group of hydrocarbons such as natural gas, etc.Containing gases such as corrosive and harmful adverse components, impurities, mists of groups of oil such as gasoline, to separate effectively the impurities and harmful substances, including components of gas hydrocarbon groups.The lubricating oil separated from the compressed gas in an oil separator provided at the discharge side of the compressor or lubricating oil returned from the bearings, shaft seals, etc. in order to prevent deterioration in the lubricity of lubricant oil.The lubricating oil is returned to an oil tank which is connected via a communication pipe to the compressor suction pipe, the oil tank is pressurized by using the suction pressure of the compressor, thus removing the components of gas dissolved in lubricating oil.The components of the gas removed is made possible to flow through a defroster to remove impurities and return via the communication pipe piping of the compressor suction, and the lubricating oil free of components of gas flows by a fine mesh filter to remove the impurez The.
