Problems solved by technology

The main disadvantages are: (1) Due to the relatively large reaction space, it is difficult to keep the temperature in the entire space at the same temperature; (2) The uniformity of the reaction is not high, which affects the product quality and reaction efficiency; (3) The energy consumption is relatively high. Big
Existing solutions cannot truly achieve continuous production

Abstract

The invention discloses production equipment and a production process for insoluble sulphur. The production equipment comprises a molten sulphur unit, a heating unit, a polymerization unit, a curing unit, a material washing unit, a separation unit, a drying unit and a granulating unit which are sequentially connected, wherein one or more of the molten sulphur unit, the heating unit, the polymerization unit, the curing unit, the material washing unit, the separation unit, the drying unit and the granulating unit comprises one or more of hollow blade structures; each hollow blade structure comprises a shell, at least one hollow shaft arranged in the shell and a hollow blade arranged on the hollow shaft; a material inlet and a material outlet are formed on the shell; and a heat exchange fluid inlet and a heat exchange fluid outlet are formed on the end part of the hollow shaft. According to the production equipment and the production process, the insoluble sulphur can be produced continuously, and the uniformity of reaction is improved. Simultaneously, a double-blade structure can be utilized in each stage of the insoluble sulphur, so that environmental parameters in the double-blade shell are set and regulated automatically in different stages.

Description

technical field [0001] The invention belongs to the technical field of sulfur production, and relates to a sulfur production equipment, in particular to a production equipment of insoluble sulfur; meanwhile, the invention also relates to a production process of the above production equipment. Background technique [0002] Insoluble sulfur is an allotrope of ordinary sulfur. It is a linear polymer polymerized by a large number of sulfur atoms. It is insoluble in sulfur dioxide and other solvents, and also insoluble in rubber, so it is called insoluble sulfur or polymerized sulfur. 1S-60 and 1S 90 on the market refer to products containing 60 and 90 insoluble sulfur components. Currently, the vast majority of insoluble sulfur produced is used in the rubber industry. Insoluble sulfur as rubber vulcanizing agent has the following advantages: [0003] a. Make the rubber material have good self-reflexivity. It can improve the bonding strength of each layer of multi-layer rubber...
