Technical Field
The present invention relates to a particulate air filter mechanism, and more particularly, it relates to a rapidly replaceable particulate air filter mechanism for a combustion engine.
Background
The air intake is arranged to provide air to buildings and/or machinery equipment or industrial processes of the equipment. Normally, the source of the air supply is ambient outside air. However, in many places, the outside air contains particles, such as dust, pollen, mold, salt particles or similar substances, which may be harmful or unwanted in the supplied air. Therefore, in many applications, the air inhaler is provided with a particle filter for removing unwanted particles of this solid from the air flow through the air inhaler.
For example, air intakes for gas turbine plants (gas turbine plants) are often provided with one or more particle filters for removing particles from the air or airflow, thereby preventing the particles from entering the turbine. Thereby, potential risk of damage, such as turbine fouling (particles sticking to rotor blades in gas turbine air compression equipment), corrosion and erosion (particles wearing rotor blades) may be prevented. Thus, a filter is provided to ensure continuous operation of the gas turbine plant, thus enabling continuous electricity generation of the output from the gas turbine plant to be maintained.
To repair a gas turbine, it may be necessary to shut down the gas turbine plant, which will result in a loss of electrical power output and an associated loss of tie-up of the equipment driven thereby. Thus, the filter in this air intake for an apparatus, for example for a gas turbine apparatus, is periodically removed and replaced by a new filter.
However, replacement of the filter may cause many problems. If the filter is removed from the suction device during operation of the device, there is a free passage for harmful particles into the device, causing the problems described above. On the other hand, the shutdown of the plant is not expected due to the complicated procedures for stopping and starting and the economic losses associated with standstill.
