A Large Gas Turbine Air Intake System

Abstract

The invention discloses a large-scale gas turbine air intake system. An air filter is arranged at the air intake of the large-scale gas turbine. The air filter is composed of a filter tube and a permanent magnet sheathed on the outer circle of the filter tube. The filter tube consists of at least four pieces arranged side by side. It is composed of a vertical ventilation pipe and an elbow. Two adjacent ventilation pipes are connected through an elbow. One end of the filter is provided with an air inlet, and the other end is provided with an air outlet. There is a first axial flow fan at the air inlet. , the air intake system of this large gas turbine has a simple structure, and the ventilation pipe is magnetized by a permanent magnet, so that the inner wall of the ventilation pipe has a magnetic adsorption of metal powder, dust and mine dust in the air, which is easy to operate, low in cost, long in service life, and the shaft The flow fan can ensure the air intake and ensure the normal operation of large gas turbines.

Description

technical field [0001] The invention relates to a large gas turbine, in particular to a large gas turbine intake system. Background technique [0002] There are dust, dust, smoke, mine dust, sand dust, metal powder and other particles in the air. If the untreated air enters the gas turbine, it will cause equipment failure and cause hidden dangers to the quality of the product. Therefore, the air in the gas turbine must be at the inlet Remove particles such as dust, dust, smoke, mine dust, sand dust, metal powder, etc., so as to prevent them from entering the downstream components of the gas turbine, causing damage to the equipment, etc., increasing costs, and some of the existing air intake systems use However, due to the large amount of impurities in the air, it is not easy to remove, and the particles such as metal powder are more difficult to remove, resulting in frequent filter replacement and high failure rate. Contents of the invention [0003] The technical problem...
