Description
Technical field
The utility model relates to drying device field, particularly a kind of fluidized bed drying equipment.
Background technology
Drying typically refers to and heat is added on wet stock and gets rid of volatility hygroscopic water (in most cases being water), and obtains the process of certain moisture content solid product.
Hygroscopic water is present in two kinds of forms in the material, a kind of is in conjunction with moisture content, and a kind of is non-binding moisture content.Hygroscopic water is present in the solid with loose chemically bound form or with liquid solution, or productive set is in the capillary structure of solid, and the vapour pressure of this liquid is lower than the vapour pressure of neat liquid, is referred to as in conjunction with moisture content.The hygroscopic water that is free in the material surface then is referred to as unbound moisture.
In fact the dry run of material generally comprises two processes, and one is the constant rate of drying process, and one is the falling-rate periods of drying process.Liquid is got rid of from the material surface with vapor form, and the speed of this process depends on temperature, air themperature, humidity and air velocity, the external conditions such as the surface area of exposure and pressure, and this process claims the external condition control procedure, also claims the constant rate of drying process.The migration of the inner hygroscopic water of material is material properties, the function of humidity and moisture content, and this process claims the interior condition control procedure, also claims the falling-rate periods of drying process.In whole dry run, two processes occur in succession, and successively control rate of drying.
Pneumatic conveying drying is a kind of of convective drying, and it is sent in the thermal current being mud shape, granular or block wet stock, also flows with it, thereby obtains being dispersed into granular dry products.
The caliber of pulse type pneumatic drier alternately dwindles and enlarges, and can give full play to accelerating sections and have high heat and mass effect, with intensified drying process.The material particle that adds at first enters in the little drying tube of caliber, and particle obtains accelerating, when its accelerated motion at the end, dry caliber sudden enlargement, particle enters the large drying tube of caliber according to inertia.Particle is in motion process, constantly slow down owing to be subject to resistance, drying tube dwindles suddenly again until slow down at the end, this like-particles is accelerated again, so repeat alternately to make caliber to dwindle and enlarge, then the movement velocity of particle is also alternately accelerated and is slowed down, and makes air and interparticle relative velocity and heat transfer area all larger, thereby has improved the intensity of heat and mass.Simultaneously, air velocity descends and has also correspondingly increased drying time in the enlarged tube.The pneumatic conveying drying dry tenacity is large, and pneumatic conveying drying can be long-pending as dry effective area all surfaces of particle because air velocity is high, and particle is good dispersion in meteorology, and therefore, dry effective area increases greatly.Simultaneously, dispersion and agitaion during owing to drying are constantly updated the gasification surface, and therefore, heat transfer, the mass transport process intensity of drying are larger.Lose heart very much time of contact of solid two-phase time of pneumatic conveying drying is extremely short, and drying time is generally at 0.5 ~ 2 second, and is the longest 5 seconds.Therefore the thermal denaturation of material generally is the function of temperature and time, for thermal sensitivity or low-melting material can not cause overheated or decompose and affect its quality.The thermal efficiency of pneumatic conveying drying is high, pneumatic drier adopts gas-solid phase cocurrent cooling operation, and at surperficial gasifying stage, material is in the wet-bulb temperature of the gas that is in contact with it all the time, generally be no more than 60 ~ 65 ℃, in the dry stage that latter stage, temperature of charge rose, gas temperature reduces greatly, and product temperature can be above 70 ~ 90 ℃, therefore, can use high-temperature gas.
Nowadays, adopt the high temperature gas flow drying to obtain in dry field using widely, various fluid bed dryers emerge in an endless stream, its calciner plant drying effect of drying machine on the market is good, but energy consumption is higher, leads xerantic cost compare height, and it is slightly aobvious complicated to operate.How just can design low energy consumption, effective, pneumatic conveying dryer simple to operate has become the problem that those skilled in the art need to solve.
