Embodiment

[0018] Preferred purity is more than 99.9% solid or liquid sulfur, it is heated up to 580~690 ℃, the mass ratio is 98.0~99.9: 0.1~2.0 carbon disulfide and unsaturated olefin mixed solvent temperature is controlled at 40~60 ℃, by The high-temperature sulfur sent from the heater at 800-1000 kg / hour and the mixed solvent sent from the circulating tank at 8000-20000 kg / hour are quenched (that is, quenched) in the synthesizer; the quenched mixture continuously enters the primary solidification In the device, keep the inclined primary curing device with the lifting plate at a speed of 0.1 to 3.0 circles per minute, and at the same time keep the liquid level of the primary curing device at 100 to 500mm below the position of the feed inlet, and keep the solid material after quenching at all times. It is in the liquid material and is continuously and slowly conveyed to the lower end of the primary curing device under the push of the copying board. The material is cured at one time durin...

Abstract

The invention relates to a method for preparing poly-sulphur, in particular to a method for continuously preparing the poly-sulphur, which comprises the following steps of: heating and warming up raw material sulphur; carrying out shock cooling on the high temperature sulphur and a mixed solvent and simultaneously carrying out rotary primary curing on the high temperature sulphur; carrying out transfer; carrying out secondary curing; carrying out filtering, collection and washing by a disk multifunctional device; carrying out spiral vacuum drying; and carrying out grinding, sieving and oil charging. The method for continuously preparing the poly-sulphur is characterized in that the method for continuously preparing the poly-sulphur comprises the following steps that: a), solid or liquid sulphur is heated to the temperature of 580 to 690 DEG C and the high-temperature sulphur sent out from a heater and the mixed solvent sent out from a circulating tank are subjected to shock cooling ina mass ratio of 1:10-20 in a synthesizer; and b), a quenched solid and liquid mixture continuously enters a primary curing device which always rotates and continuously enters a transfer tank from thelower end of the primary curing device. The method for continuously preparing the poly-sulphur has low energy consumption, high safety factor and no pollution to the environment and can be used for continuously preparing uniform and high-quality poly-sulphur products and the like.
