Embodiment: be in actual application, its concrete steps are as follows:
(1) be that 1-5mm biomass material is sent in the dry fluidizing chamber 1-1 of drying machine under the condition of the isolated air of sealing by helical feed feeder 4 by particle diameter after fragmentation, be the hot blast of 300 ± 50 DEG C to conveyor screw temperature in dry fluidizing chamber 1-1 by hot-blast conveying appliance simultaneously, and open agitating device 7, air-heater 10 is sent into hot blast in ventilation terminal 8 by hot blast conveying pipe 9, more than the wind speed of air-heater 10 is controlled at 18m/s, hot blast forms rotation wind field in ventilation terminal 8, accelerate wind speed, after making wind speed reach 30-60m/s, enter in dry fluidizing chamber 1-1, in dry fluidizing chamber 1-1, form high velocity air,
(2) moistening material is entering after dry fluidizing chamber 1-1 because the gravity of self directly falls, stirring and hot blast at agitating device 7 form under action of high-speed airflow, material after moistening caking is dispersed rapidly, with the surface area of wet stock in increment material unit volume to greatest extent; Enter the hot blast being dried in fluidizing chamber 1-1 also in high turbulence state simultaneously, reach very soon gas-solid mixing, and form the goods fluid rotating flow rotating around central axis; Adding the back taper structure of upper bottom portion, greatly increase air velocity, can ensure that piece material is surrounded by hot blast in good fluidized state; In this process, between moistening material and hot blast, also carry out the dry run of mass-and heat-transfer, most of moisture is evaporated;
(3) after the material fragmentation in dry fluidizing chamber 1-1, blown afloat from the hot air flow of bottom High Rotation Speed, relatively stable one of the interior formation of drying machine 1, the fluosolids of rotation, moisture content is high, the material density that surface area is little is large, in dry fluidizing chamber 1-1, can fall downwards, due to the high cycle speed of bottom, dropping to falling speed after certain distance is zero, now gravity and buoyant equilibrium, after material is subject to further fragmentation and moisture evaporation, buoyancy is greater than gravity, the material ascending motion of just spinning under the carrying secretly of gas, because the relation between radius of turn and pressure is that radius of turn is less, pressure is lower, so in dry fluidizing chamber 1-1 center, pressure is also minimum, near pressure maximum mixing arm 7-3, for small diameter particles, because pressure increases with the increase of radius, radial pressure is distributed uneven, in material uphill process the less moisture content of particle diameter lower than the material of 8-12% to central motion, compared with the centrifugal force producing compared with wet material greatly large and outer near machine wall, vertical type warm-air pipe 11 upwards blows out hot blast simultaneously, just the material of central part can be blown in the 1-2 of discharging chamber from the discharging opening of annular discharge baffle 12 centre, then under the drive of air-flow, enter material efferent duct 5, the position that rises to annular discharge baffle 12 near the large wetter material of machine wall, just can directly be kept off back in dry fluidizing chamber 1-1 by ring baffle 12, continues dry fluidisation, gets rid of drying machine until could enter from middle position discharging chamber 1-2 after meeting the demands,
(4) after dry in step (3), material can enter by material efferent duct 5 together with hot blast that solid and gas separates and processed, by the dried material after purification for next procedure.
In above-mentioned drying means, the wind speed of air-heater 10 is controlled by the first gas flow sensor 3-1, guarantees the abundance of air quantity, meets the interior wind speed requirement of drying machine 1; The wind speed of air-introduced machine 6 is by the second gas flow sensor 3-2 controlled wind speed, adds dry fluidizing chamber 1-1 pressure sensor 3-3 and control simultaneously the motor speed of air-introduced machine 6, guarantees that whole system is in micro-vacuum state; Discharging opening at discharging chamber 1-2 is provided with temperature sensor 3-4, is used for detecting the temperature of discharging opening material, and signal is passed to controller, by controlling its control to helical feed feeder rotating speed, regulates inlet amount, ensures outlet temperature.
