Abstract

The invention relates to a frame-type high-efficiency filter for a gas inlet system of a gas turbine, which comprises a shell (1), a first frame (51), a second frame (52) and a third frame (53) are arranged in the shell (1), and the frames are respectively provided with a first-stage filter device (6), a second-stage filter device (7) and a third-stage filter device (8); the first-stage filteringdevice (6) comprises a spiral downward primary filtering pipe (61) and side-by-side recycling pipes (62); wherein a group of recovery nozzles (63) are connected between the first-stage filter pipe (61) and the second-stage filter pipe (71), the second-stage filter pipe (71) is connected with a third-stage filter pipe (81), hemispherical convex points (82) are arranged in the third-stage filter pipe (81), and an outlet at the lower end of the third-stage filter pipe (81) is connected with an air outlet (4). The filter has the advantages of reducing the occupied area, improving the space utilization rate, being convenient to overhaul and replace a filter element, and ensuring the normal operation of the gas inlet system.

Description

technical field [0001] The invention relates to the technical field of filter equipment for gas turbine intake systems, in particular to a frame-type high-efficiency filter for gas turbine intake systems. Background technique [0002] Normally, the gas turbine intake system is composed of a closed intake chamber and an intake pipe. The downstream of the intake pipe is connected to the compressor intake. The intake system is mainly responsible for filtering and muting the air entering the unit. And introduce the air source to the inlet of the compressor. [0003] Traditional gas turbine air intake system filters are generally set to multiple levels for filtering, and the filtering devices of each level are arranged horizontally. The more filtering levels, the larger the space occupied horizontally, and the space is seriously wasted. In addition, since there are the most impurities during the initial air filtration, the first filtering instrument has to bear a large load. Whe...
