Air filter for compressor and gas turbine

The invention discloses an air filter for a compressor and a gas turbine. The air filter comprises an air inlet, a silencer, a low efficient filter, a self-cleaning filter, a guiding device, an air outlet, a backflow pipe, a pipeline, a vent hole, a filter cartridge, an air inlet passage, a separator, a first filtering plate, a second filtering plate, a metal mesh layer, filtering teeth, a filtering layer an inner plate. The air filter disclosed by the invention has the beneficial effects that the filtering layer is sufficiently utilized and has a good filtering effect; the first filtering plate and the second filtering plate can be used for filtering larger impurities in air; the first filtering plate and the second filtering plate can be detached, and the metal mesh layer inside the first filtering plate and the second filtering plate can be cleaned and repeatedly used, so that sources are saved, the filtering cost is reduced and the service life of the filter is prolonged; the separator can be used for carrying out water mist separation on air entering from the air inlet to obtain effective dry air, so that the working efficiency of the filter is improved. The air filter is used for cleaning air, has a favorable use effect and is suitable for being popularized and used.
