Claims (7)
- 액상 슬래그의 흐름을 작은 방울의 형태로 분산시키고 여기에 냉가스를 분출, 냉각시켜 고체화시킴으로써 슬래그를 입상화하는 방법에 있어서, 두께가 10내지 50mm인 액상 슬래그의 흐름을 향해 적어도 40°, 바람직하게는 70내지 110°의 각도로 압력이 10바 이상인 압축 가스를 분출시킴을 특징으로 하여 액상 슬래그의 흐름을 분산시키는 방법.
- 제1항에 있어서, 유출되는 액상 슬래그와 마주치는 고속가스의 연속적인 시트상이 형성되도록 고압가스의 분출을 조절함을 특징으로 하는 방법.
- 제1항에 있어서, 액상 슬래그의 흐름이 고압가스에 의해 분산된후 고체화된 또는 고체화되고 있는 작은 방울들을 저압으로 배출되는 유속이 큰 가스에 의해 수거 지역으로 불어보냄을 특징으로 하는 방법.
- 제1항에 있어서, 사용된 고압가스를 16내지 32바의 압력 및 20,000N㎥/분의 최저 유속으로 분출시킴을 특징으로 하는 방법.
- 제1항에 있어서, 고압가스가 압축 공기인 방법.
- 제1항에 있어서, 고압가스가 질소인 방법.
- ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
