Method and apparatus for mixing gaseous chemical to fibre suspension. |
摘要 |
<p>The present invention relates to a method of and an apparatus for mixing large amounts of gas with medium consistency (8 - 25 %) fiber suspensions by means of rotatable rotor arranged within a mixing chamber provided with various mixing members, the method mainly comprising the steps of a) introducing said gas and said fiber suspension into the mixer, b) mixing said gas with the fluidized pulp while simultaneously throttling the flow in order to prevent the influence of the pressure fluctuations due to the inlet and/or outlet flow of the fiber suspension on the mixing process and minimizing gas separation, and c) discharging the gas-fiber suspension mixture from the mixer. <IMAGE></p> |
