Method of high concentration toxic gas emission during chemical striping of gas turbine high temperature components

摘要

The present invention relates to a method of discharging a high concentration toxic gas generated during chemical stripping of high-temperature gas turbine parts, and in more detail, the upper part is opened so that the door can be opened and closed on the upper surface of the tank containing chemical substances in the internal space. When installing and performing chemical stripping, the door is closed to close the top of the tank, and at the same time, the toxic gas generated inside the tank is collected through the hood installed inside the tank, and the toxic gas generated inside the tank is collected to the outside through the discharge pipe installed on the hood It relates to a method of discharging high-concentration toxic gas generated during stripping work of high-temperature parts of a gas turbine characterized by discharging or collecting dust in a separate dust collection tank. As described above, the method of discharging high concentration toxic gas generated during the chemical stripping operation of the high-temperature gas turbine parts of the present invention is a safe operation because the upper part of the open water tank is closed with a door during the chemical stripping operation. Even after the chemical stripping work is finished, the upper part of the open tank is kept closed with a separate cover, thereby preventing the residual toxic gas from being discharged to the outside, so that it is possible to maintain a safe working environment even in daily life.
