Abstract
The utility model relates to a high-efficiency fluid dryer. Multi-hole grates in definite angle of slope with the level are installed in a housing, and the grate on each layer has a vibration device. A material inlet is provided with a vibration type feeding machine. A material outlet is provided with an aggregating conveyor. A hot air furnace generates hot fume to blow up the material through the multi-hole of the grates, which enables the material to be in a fluidized state to increase drying efficiency. The angle of slope of the grate, the vibration frequency and the amplitude of the vibration device can be adjusted aiming at different materials, being adaptable for the requirement of drying technology.
Description
The utility model is a kind of efficient fluidised form dryer of drying powder and granule shape material, belongs to the drying technology field of chemical engineering unit operation.
Dried powder and granule shape material in the past and adopted rotary dryer or oscillatory type dryer, or the boiling type dryer, preceding two kinds because of material is not fluidization, gas, solid binary states contact are inhomogeneous, heat transfer efficiency is not high, so drying efficiency is not high.Though boiling type dryer material is in the boiling attitude, gas, solid than very big causes fume afterheat temperature height, and heat loss is big, the consumption of power height.
Task of the present utility model is a kind of high-efficiency fluidization dryer of design, has single or multiple lift oscillatory type porous grate plate, carries out heat exchange with the fluidization bed of material and thermal current, makes heat exchange more abundant, thereby can reach the purpose of efficient energy-saving.
Design of the present utility model is one or more layers the porous sieve plate that installing and level are certain inclination angle in a casing, and grate plate one end is equipped with vibration source, and the inclination angle of grate plate and the vibration frequency of vibration source and amplitude are adjustable; Above first floor grate plate is high-end, the casing charging aperture communicates with the oscillatory type feeding machine, each layer grate plate be staggered inclination in casing, overlapping up and down, the low side of end layer grate plate is communicated with the scraper-trough conveyer that gathers materials, layer grate plate other end below, end is communicated with the hot-blast stove that produces hot flue gas, and above first floor grate plate, casing communicates with the dust-precipitator and the exhaust blower of purification and the useless flue gas of eliminating.
Grate plate tilt to be installed, itself and the length realization of horizontal direction inclination angle available adjustment suspension arrangement, and the inclination angle is between 17～25%, and the grate plate breadth length ratio is 1: 5～10, hole, 4～8mm garden in having on the grate plate, grate plate total void rate 2.5～4.5%.
The grate plate vibration source can be with mechanical oscillation or electric and magnetic oscillation, and vibration frequency is 500～1000 times/minute, and amplitude is 0～3mm; Vibration source is connected with grate plate one end outside casing, itself and casing gap seal with sealing device, because in the dryer is negative-pressure operation, the inside and outside junction of every casing all will seal with sealing device, as: all to connect lock wind discharge valve below gather materials scraper-trough conveyer and the rotoclone collector.
Below in conjunction with accompanying drawing 1 explanation structure of the present utility model and flow process, accompanying drawing 1 is the structural representation of an embodiment of the present utility model, numbering 1. housings among the figure; 2. material; 3. go up grate plate; 4. pendulum spring; 5. rotoclone collector; 6. flue; 7. feed bin; 8. oscillatory type feeding machine; 9. vibrating motor; 10. pendulum spring; 11. lock wind discharge valve; 12. following grate plate; 13. conveying worm; 14. grate; 15. coal bunker and coal feeder; 16. exhaust blower; 17. dust-precipitator lock wind discharge valve; 18. hot-blast stove; 19. now look into actuating doors; 20. spend blue nut and suspension rod; The scraper-trough conveyer 21. gather materials.Present embodiment has only two-layer grate plate, and grate plate vibration source vibrating motor is adjusted the grate plate inclination angle with spending blue nut and suspension rod.
When with high-efficiency fluidization drying machine drying material, material enters dryer and is laid on the grate plate (3) through vibration feeder (8), but feeding flashboard automatic lifting control feeding capacity is arranged, vibrating motor (9) can make the grate plate vibration, regulate vibration frequency and amplitude, can make that the material movement state changes on the grate plate, the grate plate upper materials is blown at the rising thermal current and is formed fluidized state down, be layered on the grate plate equably, and flow downward along the grate plate that tilts, enter down the high-end of grate plate (12) from the low side of last grate plate (3), and flow from discharge end gradually, kind character according to material, unit weight and grain composition etc. can be adjusted the vibration frequency of grate plate inclination angle and grate plate vibration source, amplitude, in the hope of reaching the optimal movement state of this kind material, material carries out heat exchange through two-layer grate plate and the hot flue gas that comes out from hot-blast stove (18), entering lock wind discharge valve (11) through the scraper-trough conveyer that gathers materials (21) transports through conveying worm (13), the smoke waste gas that has carried out heat exchange through grate plate and material to be dried by the fire enters rotoclone collector (5), gathers dust after exhaust blower (16) enters in the atmosphere.
Dust arrester installation mentioned herein, lock wind discharge valve, vibration source, the oscillatory type feeding machine, is spent blue nut and suspension rod at hot-blast stove, and sealing devices etc. all are prior arts, and those skilled in the art are known by the industry.
The utility model has the advantages that: (1) material bed blowing at certain wind speed and hot smoke gas flow Moving lower, be fluidized state, enter heat exchange with thermal current, the bed of material that is fluidized state can the edge The porous grate plate motion at certain angle of inclination, flow from feeding end to discharge end, make material Oven dry, because grate plate can be one deck, so two-layer or multilayer is but hot flue gas one or many Pass material, make heat exchange more abundant, the thermal efficiency is higher.
(2) in addition machinery or electric and magnetic oscillation of grate plate, vibration frequency and amplitude can be regulated, Thereby the kinetic stability of fluidized material is improved greatly;
(3) angle of inclination of grate plate is adjustable, and the movement velocity of adjustable material is to realize accent The drying rate of whole material, drying time, output etc.
In sum, fluidized-bed (grate plate) adds that vibration bed of material (grate plate) is material The best combination of oven dry.
This machine is compared with traditional rotating drum type drying machine, and this machine thermal efficiency is more than 85%, and rotating drum type drying machine is below 60%; Evaporation intensity reaches 500 kilograms/m
2More than, be the several times of rotary drum drying machine, even 10 times, EGT is below 150 ℃, and this machine running gear is few, and capital expenditure is economized.
