Wet forming equipment for sulphur and forming technology thereof

Abstract

The invention relates to wet forming equipment for sulphur and a forming technology thereof. An upper cooling water inlet and a lower cooling water inlet are formed in a forming tank, two branches of a water outlet of a hot water tank are connected to a hot water inlet of a heat exchanger and the lower cooling water inlet of the forming tank respectively, and two branches of a cold water outlet of the heat exchanger are connected to the lower cooling water inlet and the upper cooling water inlet of the forming tank respectively; a steam coil pipe is arranged at the bottom of a forming disc in a buckling mode, an indirect heat transmission mode is changed into a direct heat transmission mode, therefore, the heat preservation measures are more stable, and the steam usage amount can be decreased; an arc-shaped static screen is arranged between the forming tank and a vibrating-dewatering screen, the dewatering load of the vibrating-dewatering screen is reduced, therefore, the moisture content of sulphur particles screened out of the vibrating-dewatering screen is reduced, and the production efficiency is improved. According to the wet forming technology for the sulphur, the operability, adjustability and controllability of the sulphur production process are improved, and therefore not only can the resource cost be saved, but also the production efficiency and the regularity of the sulphur particles can be improved.

Description

technical field [0001] The invention relates to the technical field of sulfur granulation, in particular to a sulfur wet molding equipment and a molding process thereof. Background technique [0002] As environmental protection requirements become more and more stringent, the National Air Pollutants Comprehensive Emission Standard requires that the sulfur recovery rate of newly built sulfur recovery equipment must reach more than 99.8%. More and more sulfur is extracted as a by-product. Due to the special physical and chemical properties of sulfur, most of the liquid sulfur must be converted into regular solids for safe, reliable, and environmentally friendly transportation, storage, and use. The granulated sulfur granules have obvious advantages such as stable performance, excellent fluidity, no dust and no environmental pollution. Sulfur granulation has become an unavoidable and necessary choice for related industries. [0003] At present, there are three main sulfur gra...

AI Technical Summary

Problems solved by technology

The weakness of my country's steel belt granulator is that the equipment is difficult to run smoothly; the output of a single machine is small (the maximum output of a single machine is 5t / h); the production operation is difficult; the requirements for workers' operation level are high and the maintenance cost is high (replacement every two years expensive steel belt)

Moreover, a large part of the sulfur solid particles produced are conjoined, strip-shaped, linear, or conjoined flakes, with poor quality, many conjoined particles, high degree of crushing, and high dust

Irregular solid sulfur will cause a lot of dust during transportation and handling, which will affect the quality of sulfur
