AN APPARATUS FOR REMOVING GAS IN CONNECTION WITH A PAPER MACHINE OR CORRESPONDING

摘要

The present invention relates to an apparatus in connection with wire water treatment in the approach system of a paper machine, board machine or corresponding web formation machine, which apparatus comprises a deaeration tank (40). This tank is connected to devices for generating a vacuum inside the deaeration tank. At least one wire water feed pipe (44) extends into the tank, which pipe opens into a vacuum space above the liquid level (49) in the tank. A wire water discharge duct (46) is connected to the bottom part (43) of the tank. The feed pipe extends above the liquid level in the tank so that the wire water overflows the edge (59) of the feed pipe onto the liquid level in the tank and the wire water discharge conduit extends downward and is connected to a pump (12).
