Abstract

용해된 생성물에서 작은 입자(granule)를 제조하는 방법이 개시된다. 상기 제조과정에서 생기는 생성증기, 이 증기는 배기시에 제거되야 한다. 생성과정에서 쌓이는 조각형태의, 특히 정제형태의 생성물을 직접 형성물질로 이용하는 것이 제시된다. 이 고체편여과통은 배기흐름속에 설치되어 증기형태의 황을 결정화하는데 쓰인다. 본 발명은 황정제의 제조에 사용된다.A method of producing small granules from dissolved products is disclosed. Produced steam produced during the production process, this vapor must be removed during exhaust. It is proposed to use the product in the form of flakes, in particular, tablets, which are accumulated in the production process as a direct forming material. This solid filtration tube is installed in the exhaust stream and is used to crystallize sulfur in vapor form. The present invention is used in the preparation of yellow gold.
