Described shower nozzle has symmetrical four, all is located in the same horizontal plane.
Described material collecting device comprises micro mist collection conduit, bagroom and air exhausting device, and the micro mist collection conduit connects the drying tower bottom, and air exhausting device is connected to the opposite side of the relative micro mist collection conduit of bagroom.
Described micro mist collection conduit by drying tower to the bagroom setting that is inclined upwardly gradually.
Described air heating apparatus is for connecting the burner of natural gas line, and the burner bottom is provided with air intake.
Compared with prior art, the beneficial effect that the utility model aluminium hydroxide micro powder spray-drying installation has is:
1, drying effect is good: the shower nozzle setting that is inclined upwardly, and aluminium hydroxide micro powder slurry mist and hot-air adverse current cross, extend contact time, drying effect;
2, not agglomeration of product, not granulation, good dispersion: slip and hot-air cross by the certain angle adverse current, produce impact force, wink-dry, and not granulation, scattered;
3, cost is low: utilize the hot-air of lower temperature can reach identical drying effect, saved fuel, reduce costs.
The accompanying drawing explanation
Fig. 1 is the utility model aluminium hydroxide micro powder spray-drying installation structural representation.
Fig. 2 is the distribution schematic diagram of hot-wind inlet and shower nozzle.
Wherein: 1, hot air duct 2, drying tower 201, hot-wind inlet 3, bagroom 4, micro mist collection conduit 5, slip pipeline 6, natural gas line 7, burner 701, air intake 8, atomizer 9, shower nozzle 10, air exhausting device.
Fig. 1～2nd, the most preferred embodiment of the utility model aluminium hydroxide micro powder spray-drying installation, be described further below in conjunction with 1～2 pair of the utility model of accompanying drawing.
The specific embodiment
With reference to accompanying drawing 1: this aluminium hydroxide micro powder spray-drying installation, comprise drying tower 2, hot air duct 1, atomizer 8 and bagroom 3, the hot-wind inlet 201 that hot air duct 1 is communicated with at drying tower 2 tops, atomizer 8 is fixed on drying tower 2 circumferential upper part, atomizer 8 one ends connect slip pipeline 5, the other end connects four shower nozzles 9 in drying tower 2, and bagroom 3 connects the bottom of drying tower 2 by micro mist collection conduit 4.
The other end of hot air duct 1 is connected to the upper end of burner 7, and burner 7 lower ends connect natural gas line 6, and the bottom of burner 7 is provided with air intake 701.The utility model utilizes gas-firing to add hot-air, and cost is low.
The bottom of drying tower 2 is taper, be convenient to collect the aluminium hydroxide micro powder of dry rear whereabouts, micro mist collection conduit 4 is being obliquely installed of making progress gradually to bagroom 3 upper ends by drying tower 2 bottoms, can make like this bagroom 3 and drying tower 2 be arranged in one deck building, easy to operate, requirement to factory building is lower, and cost is low.
Bagroom 3 connects air exhausting device 10 at the opposite side of relative micro mist collection conduit 4, and air exhausting device 10 specifically can be selected the strong drawing machine.
With reference to Fig. 2, hot-wind inlet 201 is along the downward-sloping setting of drying tower 2 inwall tangential direction, make the hot blast spiral hot blast downward in the interior formation of drying tower 2, the setting that is inclined upwardly of the tangential direction of described shower nozzle 9 relative hot-wind inlets 201, the contrainjection of atomization slip enters in the spiral hot blast, and both cross at adverse current, extend contact time, drying effect is better, produces impact force simultaneously, the dried material good dispersion.
Operation principle and the course of work are as follows: natural gas line 6 provides fuel for burner 7, after igniting, air in burner 7 is heated, air exhausting device 10 is discharged to outdoor after the air in drying tower 2 and burner 7 is extracted out, drying tower 2 and burner 7 are interior can form negative pressure, air is drawn in burner 7 by air intake 701, forms the circulation of air.
The aluminium hydroxide micro powder slip is delivered to atomizer 8 through slip pipeline 5, spray in drying tower 2 and cross with hot air duct 1 hot-air out by shower nozzle 9 after atomizer 8 atomizations, shower nozzle 9 setting that is inclined upwardly, aluminium hydroxide micro powder slurry mist and hot-air adverse current cross, extend contact time, improve drying effect, slip and hot-air cross by the certain angle adverse current simultaneously, produce impact force, not granulation, scattered, the conical lower portion that dried aluminium hydroxide micro powder falls to entering drying tower 2, because the aluminium hydroxide micro powder granularity is very thin, be easy to just can be drawn in bagroom 3 through micro mist collection conduit 4, after bagroom 3 is collected, carry out the packing of aluminium hydroxide micro powder finished product below bagroom 3.
