Document Type and Number:
WIPO Patent Application WO/2021/103943
Kind Code:
A1
Abstract:
A device for spraying liquid sulfur on a coating of a granular fertilizer, comprising several hot air pipes, several temperature-resistant valves, several pressure gauges, several two-phase flow nozzles, a jacket pipe, a liquid sulfur pipe, and a return valve. The device is characterized in that: the liquid sulfur pipe is installed in the jacket pipe; the several two-phase flow nozzles are separately fixed on the jacket pipe, and the liquid sulfur pipe is connected to each two-phase flow nozzle; each two-phase flow nozzle is connected to one hot air pipe; one temperature-resistant valve and one temperature-resistant pressure gauge are installed on each hot air pipe; and one return valve is installed at the end of the jacket pipe. The jacketed liquid sulfur pipe is used for adding and conveying liquid sulfur, the material enters a wrapping drum, and the plurality of two-phase flow nozzles are used for atomization spraying to wrap the granular fertilizer.
