Abstract: The present invention concerns a method and a device for feeding at least one chemical substance into a main process stream. The method of the invention comprises the steps of providing a concentrated stream of said chemical substance, mixing said concentrated stream with a diluent stream to provided a diluted stream of said chemical substance, injecting said diluted stream of said chemical substance into said main process stream, wherein said mixing of said concentrated stream with said diluent stream is effected by injecting a jet of either one of said concentrated stream or said diluent stream into the respective other stream. The device of the invention comprises a first pipe segment (21) having a first inlet (22) for a first fluid and a first outlet (23) for a mixed fluid, a second pipe segment (24) having a second inlet (25) for a second fluid and a second outlet (26) connected to and leading into said first pipe segment (21) between said first inlet (23) and said first outlet (24), and first connection means (27) for connecting said first outlet (23) of said first pipe section (21) to a main pipe (14) of said main process stream, wherein said second pipe segment (24) comprises at least one nozzle (28) for generating a jet (29) of said second fluid arranged upstream of said second outlet (26).

Abstract translation: 本发明涉及一种用于将至少一种化学物质进料至主工艺流中的方法和装置。 本发明的方法包括以下步骤：提供所述化学物质的浓缩物流，将所述浓缩物流与稀释剂流混合以提供所述化学物质的稀释物流，将所述化学物质的稀释物流注入所述主工艺流中， 其中所述浓缩流与所述稀释剂流的混合通过将所述浓缩流或所述稀释剂流中的任一种的射流注入相应的另一种流中来实现。 本发明的装置包括具有用于第一流体的第一入口（22）和用于混合流体的第一出口（23）的第一管段（21），具有第二入口（25）的第二管段（24） 用于在所述第一入口（23）和所述第一出口（24）之间连接并通向所述第一管段（21）的第二流体和第二出口（26），以及用于将所述第一出口 （21）的主管（23）连接到所述主工艺流的主管（14），其中所述第二管段（24）包括用于产生所述第二管段（21）的喷嘴（29）的至少一个喷嘴（28） 流体布置在所述第二出口（26）的上游。
