CYCLIC AIR FILTRATION SYSTEM CIRCUIT IN THE AFCS OF THE GAS-TURBINE UNIT (VARIANTS) Russian patent published in 2018 - IPC F02C7/52 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used in power engineering, gas, oil and other industries as a filtration system for an air filtering and conditioning system (AFCS) for purifying air supplied to gas turbine and compressor units (GTU) in the amount of 20,000 m³/h to 3,000,000 m³/h. When using the first version of the circuit of the air filtration system in the cyclic air AFCS in the GTU, located inside the AFCS air duct and containing a block of filters installed along the flow of incoming air into two rows parallel to each other, while the second row of the filter block has a channel in the central area, the outer ends of the first row of the filter block are connected to the inner ends of the second row of the filter unit by means of airtight barriers extending into the channel of the central area, while air passage channels are formed when installing the filtration system in the duct between the walls of the air duct and the outer ends of the first row of the filter block, and the outer ends of the second row of the filter block are connected to the walls of the air duct. When using the second version of the circuit of the air filtration system in the cyclic air AFCS in the GTU, located inside the AFCS air duct and containing a block of filters installed along the flow of incoming air in the form of a wedge, while the widened end of the wedge is connected to the walls of the air duct.

EFFECT: technical result of the invention is the production of a compact filtration system with increased incoming air filtration efficiency by placing the filtration system inside the empty space of the air duct and increasing the area of the cleaning surface.
