Abstract
A mixing chamber and system for connecting it to a stream of inert gas, in order to monitor the stream for detecting the presence of hydrogen therein. It has a hydrogen detector in the chamber, and there is a stream of dry air mixed with the inert gas stream to provide oxygen which is required for operation of the hydrogen detector.
Claims5
A system for monitoring an inert gas stream in order to detect hydrogen therein, comprising in combination
- a chamber for passing at least a portion of said gas stream therethrough and having an inlet and an outlet,
- said chamber inlet having a reduced cross sectional area relative to said chamber,
- means associated with said inlet for diffusing mixed gas streams and for collecting any moisture therefrom,
- said diffusing means comprising a pair of perforated diffusion plates mounted on a common support and extending transversely across said inlet and said chamber adjacent to said inlet,
- means for mounting a hydrogen detector in said chamber down stream from said diffusing means, and
- means for preventing moisture from entering said outlet.
An adaptor for in-line hydrogen detection comprising in combination, an elongated cylindrical chamber member having necked down ends thereon forming an inlet at one end and an outlet at the other,
- means for diffusing incoming gas at said inlet,
- said diffusing means comprising a pair of perforated thin discs extending transversely across said cylindrical chamber adjacent to said inlet end and across said inlet end respectively with spacer means for holding said discs in place,
- means for mounting a hydrogen detector in said chamber transversely thereof and downstream from said diffusing means, and
- means associated with said outlet for preventing entry of water therethrough.
An adaptor for in line hydrogen detection comprising in combination, an elongated cylindrical chamber comprising two pressed metal portions joined by a collar,
- each of said portions having a necked down end,
- one of said ends forming an inlet and the other forming an outlet of said chamber,
- means for diffusing incoming gas at said inlet comprising
- a pair of perforated thin discs attached to an axial spacer rod and extending transversely thereof,
- one of said discs having a diameter slightly greater than the inside diameter of said pressed metal portions,
- the other of said discs having a diameter slightly greater than the inside diameter of said inlet,
- said discs and spacer rod being adapted for mounting in said inlet portion of said chamber prior to joinder of said outlet portion with said collar,
- a hole in the side of said outlet portion of said chamber adapted for mounting a hydrogen detector transversely in said chamber, and
- means associated with said outlet for preventing entry of water therethrough comprising
- a vent pipe connected to said outlet having a valve connected therein for shutting said vent when the adaptor is not being used for hydrogen detection, and
- said vent pipe ending in a half circle curve downward when the adaptor is in use in order to keep said water out.
