Abstract
A method and apparatus for separating soap from liquor in a filtrate tank are particularly well suited for treating soap-containing filtrates from digester houses, bleach plants, and washer rooms in the chemical pulp processing industry. A device is disposed in the filtrate tank for generating a horizontal draw between the soap collecting devices and the soap.
Claims10
An apparatus for separating soap from liquor in a filtrate tank comprising:
- a filtrate tank,
- a device to introduce liquor into the filtrate tank,
- a soap separating assembly having a chute for separating a soap fraction from a liquor surface in the tank and connected to convey the soap fraction out of the tank, the chute comprising a lip portion mainly receiving the soap fraction,
- a device which brings the soap fraction accumulated on the surface of the liquor and the soap separating assembly into relative motion to each other by moving the soap separating assembly in such a manner to cause relative horizontal movement to occur between the chute thereof and the soap fraction accumulated on the surface of the liquor;
- and
- a discharge to remove the soap fraction from the tank.

- a device which brings the soap fraction accumulated on the surface of the liquor and the soap separating assembly into relative motion to each other by rotationally moving the soap separating assembly, and hence said chute thereof, relative to the soap fraction accumulated on the surface of the liquor;
- and
- a discharge to remove the soap fraction from the tank.
