Problems solved by technology
However, the steam trap is prone to leakage, wasting working fluid, and affecting the overall economy of the turbogenerator
At the same time, the setting of the steam trap needs to add accessories such as isolation valves, which greatly increases the cost of use

The invention provides a high-position arrangement steam turbine drainage system which comprises a drainage header located at an elevation zero point and extending horizontally, a steam turbine generator unit located above the drainage header and provided with a drainage point, and a drainage pipeline which is vertically arranged between the drainage header and the steam turbine generator unit; and the bottom end of the drainage pipeline is communicated with the drainage header, the top end of the drainage pipeline is communicated with the drainage point of the steam turbine generator unit, a throttling structure for limiting the drainage flow speed is arranged at the position, close to the drainage header, of the drainage pipeline, and a drain valve assembly is arranged on the portion, close to the steam turbine generator unit, of the drainage pipeline. By means of the high-position arrangement steam turbine drainage system, condensate water can be prevented from entering the steam turbine generator unit, so that the scouring damage degree of drain water to the drainage header or the drainage pipeline is reduced, and the high-position arrangement steam turbine drainage system is particularly suitable for the steam turbine generator unit which is arranged at a high position and has the elevation larger than or equal to 30 m.
Description
technical field [0001] The invention relates to the technical field of steam turbines, in particular to a high-position steam turbine drainage system. Background technique [0002] The steam turbine is driven by steam, and the main body of the steam turbine and the related steam system need to be designed for drainage. On the one hand, the drainage system is used to drain the condensed water to prevent the condensed water from entering the steam turbine; on the other hand, it can also be used for the preheating of the steam turbine and related systems. [0003] The layout elevation of the steam turbine generator set in the prior art is generally less than 20m. The existing technology generally adopts a single trap or a multi-channel series trap, and the trap is arranged close to the drain header (or drain expander). [0004] For the high-level layout of the steam turbine generator set with an elevation ≥ 30m, the existing trap layout method is adopted, that is, the steam tr...
