The invention relates to a filter type
sulfur melting kettle. The filter type
sulfur melting kettle comprises a
clear liquid section, a filter section and a
sulfur melting section, all of which are orderly arranged from top to bottom, wherein a revolving filter screen is arranged in the filter section and driven by a driving device arranged at the top of the kettle; the
clear liquid section is provided with a
clear liquid outlet, while the filter section is provided with a sulfur foam inlet and the sulfur melting section is provided with a sulfur outlet. The revolving filter screen is a cage type filter screen and capable of rotating around an axis; a fixed scraper plate is arranged on the kettle body outside the revolving filter screen. Compared with the prior art, the filter type sulfur melting kettle has the following beneficial effects: 1) the revolving filter screen is capable of separating the clear liquid and the elemental sulfur in sulfur foam from each other, the sulfur is scraped into the sulfur melting section by use of the scraper plate, and the
sulfur product is good in quality and high in
recovery rate; 2)
slag is not easy to accumulate on the wall of the kettle, the kettle body of the three-section design is easy to clear and convenient to repair and replace, and the equipment
utilization rate is high; 3) the
sulfur content in the clear liquid is low, and a pipeline is not prone to block, and the clear liquid can be directly returned to the
system for utilization; 4) the equipment
controllability is high, the production process is stable, the
energy consumption is low and the production cost can be reduced.
