    • Process and apparatus for removing solids from an aqueous fiber suspension in a flotation container that includes a drainage section. The process includes adding gas bubbles to the fiber suspension entering the flotation container, and collecting a flotation foam formed within the flotation container. The flotation foam includes the solids to be removed. The process also includes laterally moving the flotation foam in the drainage section, such that at least a portion of fluid within the flotation foam is drained from the flotation foam, collecting the drained fluid in the drainage section, discharging the drained fluid from the drainage section, discharging the flotation foam as a rejects material, and discharging a purified fiber suspension as an accepted stock suspension. The apparatus includes a flotation container, and a drainage section coupled to the flotation container. The drainage section is arranged to drain at least a portion of fluid from a flotation foam. The apparatus also includes a rejects outlet coupled to the drainage section, an accepts outlet coupled to the flotation container, and a fluid collector coupled to the drainage section for collecting the fluid drained from the flotation foam.
    • 用于从包括排水部分的浮选容器中的水性纤维悬浮液中除去固体的方法和装置。 该方法包括向进入浮选容器的纤维悬浮液中加入气泡,并收集在浮选容器内形成的浮选泡沫。 浮选泡沫包括待除去的固体。 该方法还包括在排水部分中横向移动浮选泡沫,使得浮选泡沫内的至少一部分流体从浮选泡沫排出,将排出的流体收集在排水部分中,将排出的流体从排水部排出 排出浮选泡沫作为废料,排出纯化的纤维悬浮液作为公认的悬浮液。 该装置包括浮选容器和连接到浮选容器的排水部分。 排水部分布置成从浮选泡沫中排出至少一部分流体。 该设备还包括联接到排水部分的排出物出口,连接到浮选容器的接收出口以及耦合到排出部分的流体收集器,用于收集从浮选泡沫排出的流体。

    • Apparatus for removing fine impurities from a fibrous suspension comprises a dissolution device, a pre-purification device, a wet straining device, and at least one flotation device. The wet straining device comprises at least two sorting devices present in sequence, each sorting device having a wire for separating the fibrous suspension into an “accepts” portion and a “rejects” portion. The flotation device is adapted to purify the “accepts” portion of at least one sorting device, and further separates the fibrous suspension into an “accepts” portion and a “rejects” portion. The process for removing fine impurities from a fibrous suspension comprises the steps of subjecting the fibrous suspension to a dissolution process, subjecting the fibrous suspension to a pre-purification process, purifying the fibrous suspension in a wet straining process, and purifying “accepts” portions from the wet straining process by a flotation process.
    • 用于从纤维悬浮液中除去细杂质的装置包括溶解装置,预净化装置,湿应变装置和至少一个浮选装置。 湿应变装置包括依次存在的至少两个分选装置,每个分选装置具有用于将纤维悬浮液分离为“接受”部分和“拒收”部分的线。 浮选装置适于净化至少一个分选装置的“接受”部分,并进一步将纤维悬浮液分离为“接受”部分和“拒收”部分。 从纤维悬浮液中除去细小杂质的方法包括以下步骤:使纤维悬浮液经受溶解过程,对纤维悬浮液进行预净化处理,在湿应变过程中纯化纤维悬浮液,并纯化“接受”部分 通过浮选过程从潮湿过程中。
