A detailed map of the boiling process verification dryer boiling dryer

Device Overview boiling dryer boiling dryer is a drying device, also known as fluidized bed, generally by the heater, the fluidized bed [1] host, cyclone separator, bag filter, fan, operation table. Depending on the nature of the material, you may need an optional cyclone separator or bag filter. After the air is purified and heated, introduced from the bottom suction fan through the hole hopper screen. In the studio, negative pressure is formed by mixing and fluidization, after the water is evaporated and removed quickly, fast drying material. Wanji boiling dryer drying material handling work flow by car to the fluidized bed material in the cylinder by the action of lifting the seal ring and the fluidized bed. Then, the air force under the action of the induced draft fan, filtering equipment purification, after heating radiator, and then the air distribution plate (screen) partitions into the fluidized bed (drying chamber). The material inside the hopper formed under hot and stirring boiling (ie fluidized), in a large area of ??gas and solid two phase contacts, materials inside the water (or solvent) is evaporated in a short period of time and with the exhaust air away, the material is dried. Boiling drier air distribution plate has two roles, one support material layer, the second is the gas distribution. Distribution plate hole size, shape, distribution situation, the opening rate and so plays a crucial influence on the distribution of the fluid. Gas distribution is uneven, make the bed a "circulation", it tends to bed extremely easy to make some parts of a "channeling", while the remaining parts are dead bed, when most of the gas along the bed Some passages in the form of "channeling" short circuit through the bed to leave, so gas-solid contacting deteriorated significantly, which should be developed to avoid. Good distribution plate design, should be able to suppress unevenness appear bed, that is, when some parts of the bed pressure drop due to reduced airflow velocity increases, the resistance generated by the distribution board should be able to suppress an increase in the gas stream, thereby inhibiting fluidized worse.
