Introduction of pressure spray drier

Pressure spray drier is a kind of equipment which can complete drying and granulation at the same time. According to the technological requirements, the pressure, flow rate and nozzle size of the feed pump can be adjusted to obtain a certain proportion of spherical particles. Its working process is as follows: the feed liquid is input under high pressure through the diaphragm pump, sprayed in the form of fog drops, and then falls parallel to the hot air. Most of the powder particles are collected by the discharge port at the bottom of the tower, the waste gas and its tiny powder are separated by the cyclone separator, the waste gas is discharged by the exhaust fan, and the powder is collected by the pollination tube arranged at the lower end of the cyclone separator. Fan outlet can also be equipped with two-stage dust removal device, and the recovery rate is above 96-98%. The materials of towers, pipelines and separators in contact with materials are all SUS304. There is enough insulation layer between the tower and the shell, and the filling material is superfine glass wool. There are observation doors, mirrors, light sources and control instruments on the tower body, which are controlled and displayed by the electric console. Its heat source device adopts steam heating or electric heater, which has the advantages of convenient operation, fast start-up, compact structure and clean hot air. In addition, the control and adjustment device of the electric heater is installed in the electric control cabinet, which can adjust the inlet temperature steplessly. For power shortage areas, steam heating or coal-fired and oil-fired hot stoves can partially or completely replace the electric heating device.
