본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음

Claims (13)

  1. 고점도유체를 반송하고, 메인믹서(1)의 내장된 스태틱 혼합유니트(la)를 가지는 메인라인(2a)과, 메인라인으로부터 메인믹서의 입구까지 연결되는 분기흐름을 위한 분기라인(2b)과, 분기라인에 위치된 펌프(3)와, 분기라인의 단부에 배설된 스태틱 보조믹서(5)와, 저점도유체를 공급하도록 보조믹서의 입구에 배설된 노즐(40)로 이루어지고, 메인라인과 메인믹서의 분기라인은 필수적으로 평행한 축을 가지는 파이프부(24,25)로 구성되는 것을 특징으로 하는 저점도유체를 고점도유체에 혼합하는 것을 특징으로 하는 혼합장치(2).
  2. 청구항 1에 있어서, 보조믹서(5)의 출구와 메인믹서(1)의 입구 사이의 거리는 보조믹서의 내장된 혼합유니트(1b)의 직경(D)의 2배보다 작은 것을 특징으로 하는 혼합장치.
  3. 청구항 1 또는 2에 있어서, 분기라인(2b)은 메인믹서(1)의 상류의 메인라인(2a)으로부터 분기되는 것을 특징으로 하는 혼합장치.
  4. 청구항 1~3중 어느 한 항에 있어서, 메인라인(2a)은 메인믹서(1)에 선행하는 직각벤드된 형상이고, 이 직각벤드된 영역내에 보조믹서(5)가 배치되는 것을 특징으로 하는 혼합장치.
  5. 청구항 1∼4중 어느 한 항에 있어서, 보조믹서(5)는 열교환기로서 구성되는 것을 특징으로 하는 혼합장치.
