Sulfur wet forming granulation production system and production process

Abstract

The invention relates to the technical field of sulfur granulation, and in particular, relates to a sulfur wet forming granulation production system and production process. The sulfur wet forming granulation production system comprises a liquid sulfur filter, a liquid sulfur distributor, a granulation main machine, a product dehydration vibrating screen and a product conveying device which are sequentially arranged; an exhaust device is further arranged at the upper end of the liquid sulfur distributor, and a cooling water treatment integrated tank is further arranged at the lower end of the product dehydration vibrating screen; the cooling water treatment integrated tank comprises a concentration tank, a water inlet tank, a sedimentation tank and a clear water tank which are sequentiallyarranged, a fine particle spiral lifting device is arranged in the concentration tank, and a pH monitoring device is arranged in the clear water tank. According to the sulfur wet forming granulation production system and production process, a produced sulfur solid particle product is spherical in shape, smooth in surface, uniform in particle size, free of any sulfur dust, not prone to dusting during bulk transportation and bagging transportation and extremely low in surface moisture content.

Description

technical field [0001] The invention relates to the technical field of sulfur granulation, in particular to a sulfur wet-molding granulation production system and a production process. Background technique [0002] Sulfur can be processed into various industrial and agricultural products such as sulfuric acid, fertilizers, explosives, pesticides, fungicides, paper, textile and rubber products, etc. Sulfur can come from natural sulfur minerals, or from by-products of coal processing, natural gas purification and petroleum refining. Sulfur as a by-product is often discharged from the above-mentioned various processing equipment in liquid form. Liquid sulfur can be transported to various users with heated tank trucks, but liquid sulfur transportation is often expensive and inconvenient for long-distance transportation, so most liquid sulfur must be solidified into blocks or granules before being transported to various users . Since sulfur is an explosive item, any open flame ...

Problems solved by technology

However, this process has no application value in theory and practice, and will greatly increase the production cost and increase the internal stress of the sulfur product, which will be brittle and produce fine particles and dust during subsequent dehydration, handling and transportation.
