Description
Technical field
The utility model relates to a kind of drying device, is specifically related to a kind of pressure cooling spray drying device that is applicable to the material drying of various moisture contents.
Background technology
At present, the most hot blast of particle drying industry circulates in drying tower, utilize the forced ventilation effect, be provided with adjustable split-wind plate in the tower, dry materials is slower, and particle is inhomogeneous, particularly for the drying that requires to keep active biochemical product, because drying time is long, perhaps temperature keeps the too high goods activity that makes easily to be affected even to lose activity for a long time.
Summary of the invention
The utility model provides a kind of spray-drying installation at above-mentioned shortcoming of the prior art, it is slower to have overcome in the prior art dry materials, particle is inhomogeneous, particularly overcome drying for the biochemical product that requires to keep active, because drying time is long, perhaps temperature keeps too high for a long time and the goods activity is affected even deactivated technical problem.The utility model is realized in the following manner:
A kind of pressure cooling spray drying device, as shown in Figure 1, mainly by air access arrangement 1, air heating plant 22, hot blast distributor chamber 6, centrifugal spray equipment 7, drying tower 8, feeding device 11, whirlwind collecting device 14, discharging equipment 15, bag-type dust equipment 16, air-introduced machine 18, electrical control cubicles 19 constitutes, air access arrangement 1 is connected with air heating plant 22, air heating plant 22 connects hot blast distributor chamber 6, feeding device 11 links to each other with centrifugal spray equipment 7, hot blast distributor chamber 6, centrifugal spray equipment 7 is connected with drying tower 8 respectively, drying tower 8 connects whirlwind collecting device 14, whirlwind collecting device 14 respectively with discharging equipment 15, bag-type dust equipment 16 is connected, bag-type dust equipment 16 is connected with air-introduced machine 18, it is characterized in that drying tower 8 is provided with cooling interlayer 23.
Described cooling interlayer 23 is arranged on drying tower 8 bottom cones partly, and the air intake passage at air inlet 24 places is vertical with the drying tower center line.The tapered wall at described cooling interlayer 23 places becomes 30 degree angles with the drying tower center line.Described cooling interlayer 23 is provided with vibrating device 21.Vibrating device 21 is three, is evenly distributed on the tapered wall middle part horizontal plane at cooling interlayer 23 places.
The beneficial effects of the utility model: by being provided with cooling interlayer 23, make by wink-dry finished product when the drying tower bottom, because the cold air in the interlayer makes the lower taper wall keep low temperature, thereby make the materials inside forced cooling, thereby both wink-dries have been guaranteed, instantaneous temperature reduction again, kept biochemical product biologically active; Because be provided with vibrating device, cause materials inside under forced vibration, not adhere to, bond again, thereby keep uniform particles at the drying tower sidewall.Simultaneously, feed liquid is through centrifugal spray, and surface area increases greatly, and in high temperature gas flow, moment just can be evaporated the moisture content of 95%-98%, and finishing only needs the several seconds drying time.Even have the biochemical material of thermal sensitivity, because drop and hot blast and flow path direction flow, though the temperature of hot blast is higher, material can be not overheated in the water evaporates process.Because tapered wall is provided with vibrating device, dried material can not form on sidewall yet and adhere to and lump, thereby has guaranteed that product has good dispersiveness, flowability and dissolubility again.Owing to be to finish drying in moment, cool off in moment again, product can keep stable activity.For the solution energy primary drying powdering product of moisture content at 5-60% (special material can reach 90%), do not need after the drying to pulverize again and screen, reduced production process, improved the purity of product.
The utility model can be used for the drying of the variable concentrations product of following material: polymer and resinae; Dyestuff, pigment class; Pottery, category of glass; The rust cleaning class; The insecticide class; Carbohydrate; Dairy products; Blood and fish product class; The fertilizer class; Inorganic, organic compound class or the like.
