Insoluble sulfur continuous quenching device

Abstract

The invention discloses an insoluble sulfur continuous quenching device which comprises a shell, and the interior of the shell comprises a feeding quenching section, a material conveying section and adischarging section in the material flowing direction; a feeding distributor and a quenching liquid distributor are arranged in the feeding quenching section, a plurality of layers of conveying beltsare arranged in the material conveying section, fixed rotating shafts are arranged at the two ends of each layer of conveying belt, and a discharging device is arranged in the discharging section. According to the continuous quenching device for insoluble sulfur, continuous quenching of polymerized sulfur can be achieved through continuous granulation and continuous conveying, so the consistencyof the quenching time of polymerized sulfur is achieved, and the yield and the thermal stability of quenched products are guaranteed.

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...
