The utility model belongs to the technical field of intake manifolds, and provides an intake manifold device for a
compressed air system of a
power station, which comprises a steam pocket, a
reducer and a
branch pipe, two ends of the steam pocket are respectively provided with an air inlet and a water outlet, the
reducer comprises a first
reducer and a second reducer, the first reducer is connected with the air inlet of the steam pocket, and the second reducer is connected with the water outlet of the steam pocket. One end, far away from the steam pocket, of the second reducer is connected with the drain valve; a plurality of
branch pipe connecting ports are uniformly formed in the two sides of the steam pocket, each
branch pipe connecting port is communicated with a branch pipe through a branch pipe seat, and one end, far away from the steam pocket, of the branch pipe is connected with a user pipeline through a branch valve. The utility model provides an intake manifold device for a
compressed air system of a
power station, which can enable all user pipelines of the
compressed air system to be arranged in a centralized manner, realize integration, improve the space
utilization rate and facilitate the operation of overhaul and maintenance.
