Monoammonium phosphate vibrating fluidized bed dryer

Monoammonium phosphate dryer, monoammonium phosphate dryer, monoammonium phosphate drying equipment, monoammonium phosphate drying equipment, fluidized bed dryer, fluidized bed dryer, vibrating fluidized bed dryer, drying and cooling integrated machine.

Industrial grade monoammonium phosphate, also known as ammonium dihydrogen phosphate, is a white crystal, in the form of white powder or granule, with certain moisture absorption and good thermal stability. It is mainly used in the fields of quick-acting compound fertilizer, high-end compound fertilizer raw materials, fire dry powder fire extinguishing agent ingredients, lithium iron phosphate precursor raw materials, etc.

Industrial monoammonium phosphate is prepared by purification of wet-process phosphoric acid, and the technological route and conditions for producing industrial monoammonium phosphate are obtained. Wet process phosphoric acid is aged, desulfurized, defluorinated, neutralized and separated to obtain monoammonium phosphate clear solution, and then concentrated, crystallized, separated and dried to obtain industrial monoammonium phosphate crystal.

Description of equipment drying process:

The industrial-grade monoammonium phosphate fluidized bed drying system comprises a drying inlet fan, a steam heat exchanger, a vibrating drying fluidized bed, a cooling exhaust fan, a bag dust collector, a cyclone dust collector, and a second cooling fan, which is characterized in that it also comprises a steam condensate heat exchanger; Among them, the air pipe is connected to the inlet of the drying inlet fan, the outlet of the drying inlet fan is connected to the inlet of the steam condensate heat exchanger, the outlet of the steam condensate heat exchanger is connected to the inlet of the steam heat exchanger, the steam condensate heat exchanger is also connected to the desalted water station for recovering the condensate, the steam heat exchanger is also connected to the main pipe for providing steam, and the outlet of the steam heat exchanger is connected to the front air inlet pipe of the vibrating drying fluidized bed, A temperature control valve and a temperature regulating indicating device for regulating the temperature control valve are set between the outlet of the steam heat exchanger and the main pipe. The front section of the air outlet of the vibration drying fluidized bed is connected with the inlet of the cyclone dust collector, the upper outlet of the cyclone dust collector is connected with the tail gas scrubber through the first cooling fan, and the outlet of the second cooling fan connected with the air is connected with the rear section of the air inlet of the vibration drying fluidized bed, The air outlet of the rear section of the vibrating drying fluidized bed is connected to the bag dust collector through the cooling exhaust fan, the upper outlet of the bag dust collector is connected to the air pipe, the lower outlet of the bag dust collector and the lower outlet of the cyclone dust collector are connected to the recovery device through the chute, the feed inlet of the vibrating drying fluidized bed is connected to the automatic centrifuge that provides crystalline materials, and the outlet of the vibrating drying fluidized bed is connected to the product packaging device.

characteristic:

1. The material is evenly heated, the heat exchange is sufficient, and the drying intensity is high, saving about 30% energy than the ordinary dryer.

2. Good adjustability, wide adaptability, stepless adjustment of material layer thickness, moving speed in the machine and full amplitude change.

3. The vibration source is driven by vibration motor, with balanced operation, convenient maintenance and long service life.

4. Vibration is helpful to disperse particles with high moisture content, easy to agglomerate and bind, improve fluidization state, and fluidization is stable and uniform without dead space and blowthrough, so as to obtain uniform drying, cooling and humidification effect.

5. It can be used for fragile drying due to less breakage and wear of particles. The irregular particles of materials will not affect the working effect.

6. Due to the vibration, the minimum fluidization gas velocity can be reduced, so the air demand can be significantly reduced, and thus the dust layer entrainment can be reduced. The supporting heat source, fan, cyclone separator, etc. can also be reduced accordingly.
