Application of vacuum filter in desulphurization

- May 05, 2018 -

1. The production method of the rotary drum vacuum filter in the steel plant: using the current mainstream vacuum filtration method to separate the sulfur foam, this method has small area, low energy consumption, good solid liquid separation effect after treatment, and the separation of material is centralized and easy to deal with.

2, process flow: the sulfur foam from the flotation tank is transported to the foam tank through the feed pump, and the clear liquid separated from the bottom of the foam reservoir is returned to the rich liquid tank. The water content of about 85% of the sulfur foam is separated by the foam pump into the vacuum filter, the filtrate after the filter is filtered and the drainage tank returns to the system. After reuse, the sulfur paste is discharged into the sulfur paste storage tank by scraper discharge.
