Description
Technical field
The utility model relates to a kind of spray-dired equipment that is used for, and belongs to the drying machine technical field.
Background technology
Liquid material is dried to flowable, as to have certain particle size low-density powder product with spray dryer usually, according to estimates, existing surpass 20,000 spray dryers and is being used for all over the world producing.Spray-dired basic principle is that liquid material atomizing is desired granularity and size distribution, contact with high temperature unsaturation gas, drop by gas carry secretly, drying and be transported to the product gathering-device.The volume of spray dryer will make droplet have the sufficiently long holdup time, even maximum droplet also can be dried to desired final moisture content, therefore the volume of spray dryer is often very big, and its material saturation is low, the power consumption height, investment is big, and sometimes because need a large amount of dry airs, thereby energy utilization rate is lower.
Aspect large-tonnage spray-drying, the most significant development is the employing of multilevel drying.Wherein the first order is a spray-drying output moderate amount of moisture product, it is sent into very little fluid bed or Vibratingfluidbeddrier again, takes off inner moisture so that obtain the long time of staying.The second level (or third level) can be belt or percolation circulation dryer.It is original 30%～50% that this method can make the volume of spray dryer be reduced to, the corresponding drying cost that also reduced.The second level or the third level can be used for product " instant processing ", condense the rehydration and the dissolubility of promoting product by control.Therefore this technology is considered to a mature technique usually, but need demand urgently improving in the following aspects:
● higher productivity ratio;
● particle size distribution is more even;
● the collection of powder;
● reduce or eliminate wall sticking phenomenon, because sticking wall can cause fire, increase downtime, raising
Maintenance cost.
Designing new can cutting down the consumption of energy, maybe to make the more uniform atomizer of drop be very important to improving spray drying technology.Because operation or use superheated steam can make product have some unique characteristics under vacuum, these technology also can suitably be used in spray-drying.Finally, remove the size and shape of surface moisture and particle surface viscosity and control product as the first order with spray-drying, after connect cheaply drying machine and circulate and carry dry multistage operations will popularize gradually undoubtedly.
Summary of the invention
The utility model is for remedying the deficiencies in the prior art, provide that a kind of temperature with drop in rate of drying rapidly and the dry run is not high, good product quality, can make product have good dispersiveness, flowability and dissolubility, make production process simplification, convenient operation and control simultaneously, be suitable for the low pressure mixed flow type atomizing drying machine of serialization large-scale production.
The utility model is realized by the following technical solutions:
Spray dryer comprises inside and outside cylindrical shell, hot-air distributor, blast pipe, spray gun assembly, heat-insulation layer, wherein, heat-insulation layer is located at the outer wall of inner barrel, blast pipe is connected with hot-air distributor, hot-air distributor is installed in the drying tower top of being made up of inside and outside cylindrical shell, and the spray gun assembly is installed in the drying tower bottom.
Hot-air distributor is made up of wind deflector, base plate and lifting screw rod, and wind deflector and base plate are fixed, and is installed in the drying tower top by the lifting screw rod.
The spray gun assembly is made up of spring, spring stop, fixed cover, spray gun bracing piece, gun shot, shower nozzle, wherein, spring, spring stop and fixed cover are installed on the outer wall of spray gun bracing piece, and the inner chamber of spray gun bracing piece is with gun shot, and shower nozzle links to each other with gun shot.
The utility model course of work: high-temperature hot-air enters hot-air distributor from blast pipe, and high-temperature hot-air evenly is rotated down along barrel and enters in the inner barrel under the effect of hot-air distributor; Feed liquid upwards is the fountain shape ejection with not high pressure after passing through the spray gun assembly by the drying tower bottom, forms hollow cone, and the surface area of feed liquid is sharply increased.Feed liquid with carry out after the first adverse current from the hot blast of top and the motion process of the mass-and heat-transfer of stream, whole process is a mixed flow process, to reach sufficient mass-and heat-transfer, quick-drying purpose.The effect of heat-insulation layer is to reduce thermal loss; In use, feed liquid is dispersed into droplet into 10mm-60mm by spray gun, has very big evaporation surface, is beneficial to reach quick-drying purpose.The temperature that the utlity model has drop in rate of drying rapidly and the dry run is not high, good product quality, can make product have good dispersiveness, flowability and dissolubility, make production process simplification, convenient operation and control simultaneously, be suitable for advantages such as serialization large-scale production.
