Sulfur wet forming device and forming process

Abstract

The invention discloses a sulfur wet forming device and a forming process. The device comprises a forming system, a dehydration system, a cooling and dehumidifying system and a solid-liquid separation treatment system, the forming system comprises a forming disc and a forming tank; the dewatering system comprises an arc-shaped sieve and a vibration dewatering sieve; the cooling and dehumidifying system comprises a uniform distributor, a static fluidized bed and an air blower I; the solid-liquid separation treatment system comprises a hot water tank, a precipitation tank and a sand-water separator; the forming process comprises the following steps: liquid sulfur enters a forming tank through a forming disc and then is cooled and solidified to form particles, the particles are subjected to pre-dehydration and vibration dehydration and then enter a cooling and dehumidification system, the temperature of the sulfur particles is reduced to below 30 DEG C, the water content is reduced to below 0.5%, and sulfur fine powder in system process water is subjected to solid-liquid separation through a precipitation tank and then is conveyed to a remelting tank; and dust at the forming tank and the vibration dewatering screen is recycled, so that automatic innocent treatment of the fine powder sulfur is realized, the powder content in the product is reduced, and the water content of the product is reduced.

Description

technical field [0001] The invention relates to the technical field of sulfur granulation, in particular to a sulfur wet molding device and molding process. Background technique [0002] Sulfur is an important chemical product and basic industrial raw material, widely used in chemical industry, light industry, pesticide, rubber and other industries. There are very few natural sulfur mines in my country. Domestically produced sulfur mainly comes from oil refining units, and some sulfur is recovered from natural gas purification, coal chemical and other industries. Generally, liquid sulfur is obtained through the Claus method, and then solidified and granulated for convenient transportation and storage. . [0003] At present, there are three main sulfur granulation processes in the world: rotary steel belt sulfur granulation, drum granulation and sulfur wet molding. Rotary steel belt sulfur granulation and drum granulation are both dry granulation, the product has low moistur...

Problems solved by technology

[0006] In high-latitude and high-cold regions such as Northwest and Northeast my country, the water vapor in the bag will condense and freeze during storage and transportation after the product is bagged, and the particles will freeze into blocks, resulting in increased energy consumption and labor intensity for downstream equipment.
