Detailed Description

In order to make the technical means, creation features, achievement purposes and effects of the present invention easy to understand, the present invention is specifically described below with reference to the embodiments and the accompanying drawings.

< example >

As shown in fig. 1, the gas turbine exhaust gas detection device provided in this embodiment includes: collection module 10, cooling module 20, storage module 30, analysis module 40, exhaust treatment module 50, display module 60, and check valve 70.

The collection module 10 is disposed at the gas turbine measurement section for collecting the exhaust gas of the gas turbine and delivering the exhaust gas to the cooling module 20.

The collection module 10 includes a flue gas probe that extends into the gas turbine measurement section to collect the tail gas. In this embodiment, evenly be provided with a plurality of gas collecting holes on the cross-section circumference of gas turbine measurement section to can make the flue gas probe collect tail gas more evenly and detect the accuracy with promotion tail gas.

A check valve 70 is disposed between the collection module 10 and the cooling module 20, and the exhaust gas collected by the collection module 10 is delivered to the cooling module 20 through the check valve 70. The check valve 70 is provided to prevent the exhaust gas in the cooling module 20 from flowing back to the collection module 10.
