Description

Technical Field

[0001] This utility model relates to the field of fuel gas treatment technology, specifically to an on-board fuel gas treatment device. Background Technology

[0002] Some substances present in the fuel gas can negatively impact gas turbines, causing corrosion of turbine blades and pipes, clogging of fuel nozzles, reduced turbine lifespan, decreased power generation, and in severe cases, direct damage to the turbine. Therefore, filtration devices are typically installed in the fuel system of gas turbine units. Existing filtration devices include cartridge-type and cotton filter types, but their structural design is flawed. Existing cartridge-type filters are bottom-in, bottom-out filters, with the filter element only used at the bottom. The high flow rate allows many impurities to be carried downstream, and some impurities remain on the filter element mounting plate during maintenance, making maintenance inconvenient. Existing cotton filter types are also inconvenient to replace and maintain.

[0003] Patent document CN221107497U discloses a fuel gas filtration device. Fuel gas enters from the inlet and first undergoes preliminary filtration through a filter frame. After long-term filtration, the filter frame needs cleaning; simply remove the sealing ring and rotate the filter frame out. The pre-filtered fuel gas enters the connecting pipe on the right side through a conical collecting pipe, where its impact force is increased. It then passes through conveying pipes of varying lengths to the cavities of the spiral adsorption filter plate. After thorough adsorption by the spiral adsorption filter plate, it is discharged from the outlet. When the fuel gas contacts the spiral adsorption filter plate, it travels in a spiral. When the fuel gas pressure is high, the fuel gas flow rate is high, and some impurities in the fuel gas cannot be effectively adsorbed by the spiral adsorption filter plate. Simultaneously, impurities entering the chamber of the spiral adsorption filter plate are difficult to remove. Utility Model Content
