Abstract

A silencer includes a main body provided with a flow path having inlet and outlet ports of steam, configured such that the outlet port is submerged in drain, and including a submerged portion configured such that the steam contacts, in the flow path, the present drain having flowed in through the outlet port, and a porous member covering the outlet port.

First claim

What is claimed:

1. A silencer comprising:
a main body provided with a flow path having inlet and outlet ports of steam and including a submerged portion configured such that the outlet port is submerged in a drain fluid flowing in a drain recovery pipe and the steam contacts, in the flow path, the present drain fluid having flowed in through the outlet port; and
a porous member covering the outlet port; wherein
the outlet port includes multiple outlet ports provided at the submerged portion, and
the flow path includes
a mixing portion provided at the submerged portion, communicating with the inlet port, and configured such that the steam is mixed with the drain fluid, and
multiple communication paths provided at the submerged portion and causing the mixing portion and the multiple outlet ports to communicate with each other.

2. The silencer according to claim 1 , wherein
the submerged portion is formed in a circular columnar shape, and
the multiple outlet ports are arranged in a circumferential direction of the submerged portion, and open at an outer peripheral surface of the submerged portion.

3. The silencer according to claim 2 , wherein
each outlet port is formed in an elongated shape extending in an axial direction of the submerged portion.

4. The silencer according to claim 3 , wherein
the mixing portion is provided at a center of the submerged portion in a radial direction thereof, and
each communication path is connected to the mixing portion and an end portion of a corresponding one of the outlet ports in an axial direction thereof.

5. The silencer according to claim 1 , wherein
the inlet port has a nozzle portion provided at other portions of the main body than the submerged portion and configured to spray the steam to the mixing portion.
