Detailed description of the invention
Below with reference to accompanying drawing, the present invention is described in detail.
Shown in composition graphs 1, heat-circulation type pressure spray drying tower disclosed in the present embodiment, comprises drying tower body 1, deduster 2, heat exchanger 3, mechanical compress wind 4, air-heater 5, storage tank 6, pump 7, fluid bed 8, screen vibrator 9.Drying tower body 1 is provided with the chamber door (not shown) that can open or close, the effect arranging chamber door can make drying tower apparatus facilitate air to enter the inside of drying tower body 1 when starting preheating, preferably, chamber door can be arranged to have transparent part, the working condition in handled easily personal observations drying tower; Be communicated with deduster 2 in the bottom of drying tower body 1, as preferably, sack cleaner selected by deduster 2, can filter out the dust of in gas 96% to 98%; What be communicated with deduster 2 is heat exchanger 3, the gas heat of drying tower body 1 inside and drying tower body 1 ambient air can be carried out heat exchange by heat exchanger 3, make drying tower body 1 ambient air temperature increase, be convenient to the efficiency improving the intensification of drying tower body 1 internal gas; What be communicated with heat exchanger 3 is mechanical compress blower fan 4, mechanical compress blower fan 4 can carry out Fast Compression intensification to gas, and the gas after compression being heated up sends into the inside of drying tower body 1, the heat that drying tower body 1 is discharged can be recycled, reduce heat dissipation.
Material is stored in storage tank 6, and by pump 7, material is pressurizeed, preferably, pump 7 is high-pressure pump, by pump 7, material is entered the inside of drying tower body 1 with atomized spray, the drop after atomization, surface area increases greatly, ensure that and fully the contacting of drying tower body 1 hot inside air, dry run can be completed rapidly.
Hot bellows 5 is provided with on the top of drying tower body 1, compressing the hot gas after heating up through mechanical compress blower fan 4 is sent in the hot bellows 5 on drying tower body 1 top, the effect of hot bellows 5 evenly divides wind, make all even material contact of hot gas entering drying tower body 1 inside, avoid due to heat skewness, the phenomenon that thermo-color crossed by dry powder occurs.
Hot gas is after hot bellows 5 evenly point wind, ensure the inside entering drying tower body 1 with the flow velocity of 10m/s, and ensure that the inside of drying tower body 1 spurted into by the material sprayed after pump 7 pressurizes with 150m/s, hot gas and material carry out heat exchange in drying tower body 1 inside, and the drying effect of material can be made to reach best.
The discharging opening of drying tower body 1 is connected with the feed end of fluid bed 8, and the discharge end of fluid bed 8 is provided with screen vibrator 9, and screen vibrator 9 can shake to dry powder-shaped material and sieve process, makes the material after process more even, is convenient to storage and the packaging in later stage.
To the course of work of the present embodiment be specifically described below:
When drying tower apparatus is in preheat mode, need the chamber door first opening drying tower body 1, be beneficial to air and enter drying tower body 1 inside, aspirated by the air of mechanical compress blower fan 4 pairs of drying tower body 1 inside, make air successively by the deduster 2 that is communicated with drying tower body 1 bottom and heat exchanger 3, the air after heating up is compressed after hot bellows 5 evenly point wind through mechanical compress blower fan 4, air flows back into the inside of drying tower body 1, circulation like this, heated up by the continuous compression of mechanical compress blower fan 4 pairs of air, the air themperature of drying tower body 1 inside can be made to be preheated to rapidly the temperature required 150-180 DEG C of work, wherein deduster 2 can carry out dust removal process to the air flowed through, the gas heat of drying tower body 1 inside and drying tower body 1 ambient air can be carried out heat exchange by heat exchanger 3, make drying tower body 1 ambient air temperature increase, and are convenient to the efficiency improving the intensification of drying tower body 1 internal gas.
After preheating completes, when drying tower apparatus is in normal operating conditions, need the chamber door of closing drying tower body 1, now the air of drying tower body 1 inside is successively by after deduster 2, heat exchanger 3, mechanical compress blower fan 4, defines closed heat circulating system; When spraying into drying tower body 1 after material pressurizes from storage tank 6 by pump 7 and being inner, material is spray form spurts into drying tower body 1 inside with the speed of 150m/s, and come in contact with the hot-air circulated with 10m/s flow velocity in drying tower body 1 inside, flash evapn falls the moisture content in material, now dried material can flow into fluid bed by the discharging opening of drying tower body 1, processed by the sieve that shakes of fluid bed to the collection of material and screen vibrator, pulverous finished product can be formed; And the air themperature after drying tower body 1 internal heat exchange is usually between 80-90 DEG C, this partial air is by the dust removal process of deduster 2, and utilize mechanical compress blower fan 4 to carry out continuation compression to it to be warmed up to 150-170 DEG C, and after evenly dividing wind by hot bellows 5 to it, send into drying tower body 1 inner, so circulate; Relative to prior art, this heat-circulation type pressure spray drying tower has carried out again utilizing to the hot-air with a large amount of steam that drying tower body 1 is discharged, thus has saved a large amount of energy, reduces the operating cost of enterprise.
Heat-circulation type pressure spray drying tower equipment disclosed by the invention, need from device external suction air during preheating, but do not need supplementing of extraneous air when reaching normal operation, form closed thermal cycling profile, therefore in dry materials process, avoiding material to carry out secondary with extraneous air and contact, is very favorable for the strict food of hygienic requirements, pharmaceuticals industry.
The present invention can realize being rapidly heated to drying tower body interior air, and can recycle the heat that drying tower is discharged, and reduces heat dissipation, reduces energy consumption, cost-saving.
The exemplary illustration of above embodiment just to this patent, does not limit its protection domain, and those skilled in the art can also change, as long as no the Spirit Essence exceeding this patent, in the protection domain of this patent its local.
