Problems solved by technology

This structure has the following disadvantages: (1) Small particles of welding slag and other impurities generated during the processing of parts are easy to enter and accumulate inside the perforated steel plate, and it is difficult to clean them in place. Small particles of welding slag and impurities are easy to fly out from the small holes of the perforated steel plate after being quickly impacted by high-temperature gas, causing damage to the gas turbine unit; (2) When the sound insulation system is installed, the burr on the surface of the perforated plate is facing When the gas turbine is running, the burr surface is directly in contact with the airflow in the channel. When the gas turbine is impacted, the unevenness of the burr surface will not only generate additional noise, but also affect the overall flow performance of the airflow; (3 ) sound insulation system to achieve the best sound insulation effect, it is necessary to select different types of sound insulation cotton according to different climate and geographical environment factors, as well as the model and power of the gas turbine, and the existing structure welds and fixes the sound insulation cotton to the inlet of the transfer section It is impossible to freely replace the sound insulation cotton inside the channel, and it cannot meet the working requirements of replacing the sound insulation cotton according to the actual working environment; (4) the sound insulation system is arranged inside the air intake channel, and there is still a shortage of inconvenient maintenance; (5) ) The intake channel of the transition section is made of stainless steel. Although the surface of the stainless steel parts has been pickled to form a protective oxide film, it has been used for a long time in areas with severe wind and sand erosion and acid corrosion such as deserts, oceans, and Gobi. It is inevitable that the surface of the intake channel of the joint will be damaged, which will affect its performance

Abstract

The invention provides an outer sound insulation type gas turbine switching segment air inlet channel of a corrugated plate structure. The channel comprises a switching segment air inlet channel body,sound insulation cotton blocks and a corrugated plate; rib plates are arranged on the outer surface of the switching segment air inlet channel body, the outer surface of the switching segment air inlet channel body is partitioned into multiple space areas through the rib plates, the shape of the sound insulation cotton blocks is matched with the shape of the space areas, the space areas are filled with the sound insulation cotton blocks, the corrugated plate covers all surfaces of the switching segment air inlet channel body filled with the sound insulation cotton blocks, and the corrugated plate is fixed to the switching segment air inlet channel body through a screw. The outer sound insulation type gas turbine switching segment air inlet channel can achieve convenient replacement and overhauling of a sound insulation system, regeneration noise is reduced, and the service life of the outer sound insulation type gas turbine switching segment air inlet channel is prolonged.

Description

technical field [0001] The invention belongs to the field of gas turbine intake passages, in particular to a gas turbine transition section intake passage with a corrugated plate structure. Background technique [0002] The sound insulation system of the air intake passage of the existing gas turbine transition section is arranged inside the intake passage, specifically, a shelf is welded on the inner wall of the intake passage of the gas turbine transition section, and the sound insulation cotton is placed on the shelf to make the sound insulation cotton fit The inner wall of the air intake channel of the transition section, and then weld the perforated steel plates at both ends of the shelf to fix the sound insulation cotton inside the perforated steel plates. This structure has the following disadvantages: (1) Small particles of welding slag and other impurities generated during the processing of parts are easy to enter and accumulate inside the perforated steel plate, an...
