发明名称 Method and apparatus for the discharge of gas from a liquid solids mixture.
摘要 <p>The present invention relates to a method and an apparatus for the discharge of gas from a liquid-solids mixture. The apparatus in accordance with the invention may be applied in such places where air is separated from a medium by means of reduced pressure/vacuum. The apparatus in accordance with the present invention is especially applicable for the pulp and paper industry in situations where gas has been separated from the fiber suspension, but where the gas contains some fibers or other solids, which must be separated from the gas flow prior to the vacuum pump generating suction. The method in accordance with the present invention is characterized in that fraction containing gas, liquid and solid material is passed from the pulp treatment apparatus to a separate separating apparatus, solids are separated from said fraction, said solids are discharged from the separation apparatus, gas/gas-liquid mixture is guided to the vacuum apparatus and said gas/gas-liquid mixture is discharged from the system. The apparatus in accordance with the present invention is characterized in that it comprises a separating apparatus with a separation chamber (98) and an impeller (100) and a vacuum apparatus (108). &lt;IMAGE&gt;</p>
