Accompanying drawing explanation
for ease of explanation, the utility model is described in detail by following preferred embodiment and accompanying drawing.
fig. 1 is the fluidizing drying bed overall schematic of a kind of novel multi-wind-chamber of the present invention;
fig. 2 is the fluidizing drying bed air distribution plate perforate of a kind of novel multi-wind-chamber of the present invention schematic diagram.
The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
In order to overcome traditional fluidizing drying bed deficiency, the utility model provides a kind of new design.
A kind of novel multi-wind-chamber is fluidizing drying bed, comprises hot air chamber, boiling-house 10, expansion chamber 12; Described hot air chamber is arranged on below boiling-house 10, and a side of described boiling-house 10 is provided with charging aperture 1, and the opposite side of described boiling-house 10 is provided with discharging opening 8; Between described boiling-house 10 and hot air chamber, be provided with air distribution plate 3; Described air distribution plate 3 leans on the ventilative rate of charging aperture 1 one sides higher than the ventilative rate of nearly discharging opening 8 one sides; Between described discharging opening and hot air chamber, be also provided with cold air chamber.
Described hot air chamber specifically comprises the first air compartment and the second air compartment, and described the first air compartment and the second air compartment are set up in parallel, and described the first air compartment is positioned at charging aperture one end, and described the second air compartment is positioned at discharging opening one end.
Specifically, the ventilative rate of corresponding the first hot air chamber 4 of described air distribution plate 3 is higher than the ventilative rate of corresponding the second hot air chamber 5 of described air distribution plate 3.
Under the identical condition of air compartment area, the temperature of the first air compartment is apparently higher than the second air compartment, because charging aperture 1 is near the first air compartment, therefore above the first air compartment, need unnecessary the second air compartment of dry wet stock, and the humidity of the first air compartment top wet stock will be apparently higher than the second air compartment, so design like this makes, and the first air compartment hot blast rate is large, temperature is high, has optimized drying condition.Meanwhile, the function because air distribution plate 3 oriented after-blow when structure is set in bubble drying moves material, makes the wet stock entering bed after the higher a large amount of dehydrations of the first hot air chamber 4 of temperature, moves into the second hot air chamber 5.Lost the material of large quantity of moisture, at than the low temperature of the first hot air chamber 4 air compartments, continue to be dried, evaporate remaining a small amount of moisture, and it is too many to be unlikely to raise the temperature, thereby can reach, make dry materials, can reach again the object that rational allocation heat, the thermal efficiency are high, reduce energy consumption.The utility model obtains when ventilative rate 3.7 best results of ventilative rate 4.4, the second hot air chamber 5 of the first hot air chamber 4 through experiment, air compartment approximately 55% before hot-air quantity delivered now, rear air compartment approximately 45%.
Between described cold air chamber 7 and the second hot air chamber 5, be also provided with insulating space 6.The material that has evaporated residual moisture at the second hot air chamber 5 climb over downflow weir 9 fall with relatively low temperature enter cold air chamber 7 carry out cooling, dried material after cold air chamber 7 is cooling by discharging opening 8 dischargings of a side.Owing to being also provided with insulating space 6 between described cold air chamber 7 and the second hot air chamber 5, cut off the temperature transmission between hott bed, cold bed, when making cooling effect reach very large lifting, also reduced the waste of hot air chamber heat.
Between described cold air chamber 7 and the second hot air chamber 5, downflow weir 9 is set, the height root Ju fan pressure of described downflow weir 9 and the characteristic of dried material and the required thickness of bed layer of dry amount are adjusted, to adapt to the requirement of different material.
The cross-sectional area of described expansion chamber 12 is greater than the cross-sectional area of described boiling-house 10, between described expansion chamber 12 and boiling-house 10, is provided with separated deflector 11.Expansion chamber utilizes expansion space attenuating air velocity to reach the effect that makes granular material sedimentation separation.Described wet stock dried tail gas after drying, under the effect of air-introduced machine, rises to segregation section by boiling-house and rises to expansion chamber again, due to space and structure, limits, and expansion chamber expanding reach can not be done too greatly, so separate and subside effect has certain weakening.Now at expansion chamber, set up the rising of the granular material that separated deflector 11 carries secretly in can effectively suppressing tail gas, strengthen separate and subside effect.Under separated deflector 11 effect of setting up at expansion chamber, the granular material that tail gas is carried secretly obtains separated largely, enters cleaner and removes after residual powder emptying.If air-flow is too little, the moisture content of separating out during dry materials is difficult for rising, and can have a strong impact on drying effect.Take and be dried wet salt as example, when test determination air velocity reaches 0.8m/s, can reach more satisfactory drying effect.Wet salt tail gas under this air velocity below general granularity 0--0.9mm is carried secretly more.
One sidewall of described boiling-house caves inward, and forms a recess, and described charging aperture is arranged on this recess, and the madial wall of described recess and air distribution plate form little air compartment.Wet stock enters drying bed front portion from the recessed charging aperture 1 of drying bed boiling-house, because charging aperture is recessed setting, make the wet stock segment distance that entered a drop point forward, and because charging aperture 1 is recessed setting, the madial wall of described boiling-house 10 recess and air distribution plate have formed one and have increased the little air compartment 2 of 20% left and right area, the drop point area that strengthens wet stock is set like this, improved the decentralization of wet stock, increased the wet stock time of staying, strengthened the process of wet stock and hot-air heat and mass, improved the thermal efficiency, can overcome the drawback of the stifled bed of caking.
The beneficial effects of the utility model are: the thermal efficiency is high, the stifled bed of caking less, tail gas carries secretly less, cold bed good cooling results.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all interior done any modifications in the spirit and principles in the present invention, be equal to and replace and improvement etc., all should be included in protection scope of the present invention in.
