Abstract

The invention discloses a gas turbine casing, which comprises a waste heat exhaust pipe, a sound insulation box, a ventilation system, an entrance door, an air inlet and a straight ladder, the sound insulation box is a closed cubic structure, and the waste heat exhaust pipe Set above the sound insulation box, the ventilation system is set behind the sound insulation box, the entrance door is set on the side wall directly in front of the sound insulation box, the air inlet and the straight ladder are set on the side wall of the sound insulation box, There are spare exhaust pipes, bypass chimneys and compressor exhaust pipes on the top of the sound box. The spare exhaust pipes lead to the outside world and the inside of the sound insulation box. There is a switch gate at the connection with the sound insulation box. The bypass chimney and compressor exhaust pipe are respectively connected to the other two outlets of the three-way baffle connected to the turbine in the sound insulation box; this product can not only reduce noise, but also reduce temperature, heat insulation and explosion protection, and the noise reduction value The temperature is not lower than 60 decibels, and the heat insulation and temperature reduction is not less than 130 degrees. The waste heat emitted by the gas turbine and the combustible gas that may leak are discharged outside the plant through the forced ventilation system.

Description

technical field [0001] The invention belongs to the technical field of equipment, and relates to a casing of a gas turbine. Background technique [0002] With the rapid development of China's economy, my country's electric power industry has seen a prosperous scene, especially the development of gas turbine power plants is particularly rapid. A gas turbine is a high-speed operating power plant. During its operation, a lot of noise and heat are generated due to friction and gas flow. Therefore, it is necessary to install a casing outside the gas turbine to make it in a heat-insulating, noise-reducing and well-ventilated seal. inside the space. [0003] At present, domestic gas turbine power plants mainly use casings capable of sound insulation and sound absorption to reduce the noise of gas turbine units before the noise reaches the sound receiving point. The wall of which the bottom of the stringer is connected to the chassis of the gas turbine. The casing connected to th...
