An improved anode, cup and conductor assembly for a reactor vessel includes an
anode assembly supported within a cup which holds a supply of process fluid. The
cup is supported around its perimeter within the reactor vessel. The anode assembly
has an anode shield carrying an anode, the anode shield having upwardly extending
brackets with radially extending members. A diffusion plate is supported above
the anode by the anode brackets using first bayonet connections. The anode shield
and the anode are supported from below by a delivery tube which also serves to
deliver process fluid to the cup. A second bayonet connection is provided between
a top portion of the delivery tube and the anode assembly. The fluid delivery tube
has a fixed height within the vessel. The anode elevation is adjusted by the interposing
of a spacer of desired thickness between the anode and the tube. An electrical
conductor is connected to the anode, and passes through the tube to be electrically
accessible outside the vessel. The conductor is connected to the anode with a plug-in
connection which is completed when the tube is coupled to the anode by the second
bayonet connection. A spring loaded bellows seal and a corrugated sleeve seal the
electrical conductor from the anode, through the delivery tube, and to the outside
electrical accessibility. The diffusion plate and the anode assembly are installable
and removable from a top side of the reactor vessel using a tool which is lockable
to the diffusion plate or to the anode. The tool provides a handle for manual engagement
or disengagement of the first and second bayonet connections.
