FIELD: purification of gases. SUBSTANCE: with the aid of exhaust hoods, product portion first as vapor and then as dust is aspirated and further removed. Difference between the melt vapor pressure and saturation pressure in space is proposed to be maintained as small as possible to prevent at a maximum the product from forming vapor. It also results in lesser removable dust formation. Invention may be applied for granulators, in particular, for sulfur. EFFECT: reduced pollution of air to be cleaned. 1 dwg |
