Device for dispersing a solid in waste water

摘要

The stainless steel device (10) for dissolving and/or suspending a solid in waste water guidable by the device, comprises a container (12) for receiving the solid, an inlet (14), through which the waste water is introducible into the container and to the solid, an outlet (16), through which the solid suspended and/or dissolved in the waste water is derivable from the container, a stirrer (18) for mixing the solid and the waste water into the container, and a pump for pumping the waste water through the inlet into the container and the solids through the outlet from the container. The stainless steel device (10) for dissolving and/or suspending a solid in waste water guidable by the device, comprises a container (12) for receiving the solid, an inlet (14), through which the waste water is introducible into the container and to the solid, an outlet (16), through which the solid suspended and/or dissolved in the waste water is derivable from the container, a stirrer (18) for mixing the solid and the waste water into the container, a pump for pumping the waste water through the inlet into the container and the solids through the outlet from the container, and a distributor cone for the waste water supplied over the inlet in the container. The waste water is pumpable against the force of gravity through the container. The inlet has a check valve. The stirrer has two agitating sheets. The container has a cylindrical body. The wall strength of the container is 3 mm. The container has a height of 2.2 m and a diameter of 1.2 m. The inlet is formed, so that the waste water is introducible in the middle of the container. The stirrer has a shaft with a diameter of 40 mm. The waste water contains activated sludge in a dry weight content of 2-5%. A chemical dissolution of the solid occurs in the waste water. The solid is an inorganic material.
