Description

Filter screen supporting structure for oil separator Technical Field The utility model relates to the technical field of refrigeration equipment, in particular to a filter screen supporting structure for an oil separator. Background At present, when a compressor of a refrigeration system is operated, low-temperature low-pressure gas is changed into high-temperature high-pressure gas through compression, and then the gas enters heat exchange equipment such as a condenser for heat exchange. The compressor in the refrigerating system is mostly cooled or lubricated by oil injection, so that lubricating oil is inevitably entrained in compressed gas, the lubricating oil is a medium with poor heat exchange performance, if too much lubricating oil enters the system, the heat transfer coefficient can be greatly influenced, the refrigerating capacity of the system is reduced, a first separation filter screen is usually arranged at an air inlet of the existing oil separator product and is used for filtering oil in a gas-oil mixture from the compressor, a plurality of liquid baffle plates are arranged between the first separation filter screen and a discharge pipe to realize secondary separation, an oil filter screen is finally arranged at the tail end of the equipment to realize final separation, and dirt and abrasion on the filter screen are increased gradually along with the increase of the service time of the equipment, and the oil-gas separation effect can be influenced by untimely replacement.
