Abstract
A process for granulating sodium sulfide includes such steps as charging 60% sodium sulfide solution into storage tank, pumping it to granulator, spraying it from granulator to granulating tower while feeding cold air in bottom of the tower, cooling said solution by cold air in tower to obtain granular sodium sulfide, and packing. Its advantages are easy dissolving, transportation and packing, and low cost.
Description
The present invention is a kind of process for granulating sodium sulfide, belongs to chemical field.
The Sodium Sulphide of producing is many at present exists with blocky form, and packing needs to use metal bucket.Blocky Sodium Sulphide product is difficult for molten, uses inconvenience, the inconvenience transportation.In addition, owing to adopt the metal bucket packing, increased cost.
The objective of the invention is and Sodium Sulphide will be produced particulate state, so that dissolving, packing and transportation.
Process for granulating sodium sulfide of the present invention is, with content is that 60% sodium sulfide solution is put into the finished fluid storage tank, with pump sodium sulfide solution is squeezed into Fitz chilsonator again, sodium sulfide solution sprays into prilling tower by Fitz chilsonator, at the bottom of tower, in tower, send freezing air simultaneously, the sodium sulfide solution of ejection forms granular Sodium Sulphide through cooling in tower, use plastic bag packaging then; The temperature of squeezing into the sodium sulfide solution of Fitz chilsonator is 135～145 ℃; The temperature of the freezing air that send in tower is controlled at 15～25 ℃; Pressure-controlling in the Fitz chilsonator shower nozzle is at 1.9～2.5KG/CM
2, the aperture on the shower nozzle is 2.5～3.0 millimeters.
Present technique by control Fitz chilsonator shower nozzle pressure, aperture and send into freezing air amount in the prilling tower, Sodium Sulphide particulate temperature is controlled at 75～85 ℃.Sodium Sulphide is produced particulate state, overcome the above-mentioned deficiency of block Sodium Sulphide, make Sodium Sulphide easily dissolve, transport, pack, reduced cost.
Embodiment:
Process for granulating sodium sulfide of the present invention is, with content is that 60% sodium sulfide solution is put into the finished fluid storage tank, with pump sodium sulfide solution is squeezed into Fitz chilsonator again, sodium sulfide solution sprays into prilling tower by Fitz chilsonator, at the bottom of tower, in tower, send freezing air simultaneously, the sodium sulfide solution of ejection forms granular Sodium Sulphide through cooling in tower, use plastic bag packaging then; The temperature of squeezing into the sodium sulfide solution of Fitz chilsonator is about 140 ℃; The temperature of the freezing air that send in tower is controlled at about 20 ℃; Pressure-controlling in the Fitz chilsonator shower nozzle is at 2KG/CM
2About, the aperture on the shower nozzle is 3 millimeters.
