Question: (DMTO) Olefin separation unit: What is the structure of the oil filter in the turbine lubricating oil system? The oil filter is mainly composed of a housing, a filter element, and a three-way switching valve. To ensure the cleanliness of the turbine oil system, two fine oil filters are installed after the oil cooler; the two filters are connected in parallel through a three-way selector valve. When one oil filter is in use, another serves as a backup, allowing the filter element to be cleaned or replaced without shutting down the system. The housing of the oil filter shall meet the specifications outlined in the design documents, depending on the pressure operation level, in order to withstand a certain level of pressure. The filtering element of the oil filter is a replaceable filter cartridge with a permeability of 10um, and the pressure difference it can handle must comply with the requirements specified in the design documents. The filtration precision of ordinary oil filters is 20-40um. A pressure differential gauge is installed between the inlet and outlet of the oil filter; when the pressure difference before and after the filter is high, it indicates that there is more debris on the filter element, resulting in increased resistance, and it is necessary to clean or replace the filter element.

Answer: The lubricant filter makes more efficient use of the internal space, eliminating the space waste associated with traditional side-entry designs. The upper cover can be opened to allow for quick and easy replacement of the filter element; unlike in traditional side-entry models, where the filter element must be removed and pressed against the ring seal before replacement, this reduces the risk of secondary contamination. The liquid inlet pipe is wide and smooth, and the interior of the upper cover is shaped like a funnel, which enables automatic pressure distribution as the liquid enters. This results in less impact on the filter element, leading to faster and more stable filtration. Typical filtration devices use various porous materials or membranes, or take advantage of differences in density between oil and impurities along with centrifugal force to achieve separation. The filtering materials used include cotton cloth, felt, metal mesh, and perforated metal sheets, among others.
