A continuous quenching device for insoluble sulfur

Abstract

The invention discloses a continuous quenching device for insoluble sulfur. The quenching device includes a shell, and the inside of the shell includes a feeding quenching section, a material conveying section and a discharging section according to the flow direction of the material; the feeding The quenching section is equipped with a feed distributor and a quenching liquid distributor. The material conveying section includes several layers of conveyor belts. Both ends of each layer of conveyor belts are equipped with fixed rotating shafts, and a discharge device is installed in the discharge section. The insoluble sulfur continuous quenching device can realize continuous quenching of polymerized sulfur through continuous granulation and continuous transportation, achieve the consistency of quenching time of polymerized sulfur, and ensure the yield and thermal stability of quenched products.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a continuous quenching device for 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-efficiency r...
