Abstract

The invention discloses an insoluble sulfur production system. The system comprises a polymerization kettle, a quench tower, a washing filter and a dryer, the quench tower comprises a shell, and the interior of the shell sequentially comprises a feeding section, a quenching section, a pelletizing section and a curing section from top to bottom; and the feeding section is internally provided with a strip extruding device and a feeding hole, the quenching section is provided with a solvent inlet, a quenching water inlet and a liquid circulating inlet, the pelletizing section is internally provided with a material collecting facility, a material pelletizing reamer and a driving facility, and the curing section is internally provided with a filter screen, a discharging hole and a liquid circulating outlet. According to the system disclosed by the invention, continuous quenching and curing operation of the polymerized sulfur is realized through an integrated process of strip extruding, pelletizing, curing, extracting and crushing. According to the system, the operation process is shortened, the sulfur particle system is prevented from being blocked, and the production process has the characteristics of safety, reliability, simple equipment and operation, low operation cost, obvious energy-saving effect and the like.

Description

technical field [0001] The invention belongs to the technical field of petrochemical industry and relates to a production method and production system of insoluble sulfur. Background technique [0002] With the sharp increase in oil consumption, global oil resources are increasingly scarce, and the quality and inferiority of refinery raw materials are becoming more and more serious. At the same time, environmental protection regulations in various countries are becoming stricter, and the control of total sulfur content in petroleum products and natural gas is becoming more stringent. Therefore, the capacity of sulfur recovery units in major refineries and natural gas purification plants has increased rapidly. The domestic and foreign markets of this common sulfur have become saturated, so the price is low. How to provide high value-added sulfur products that are in short supply in the market has become the focus of relevant enterprises. [0003] Insoluble sulfur is a high-...
