Description
Technical field
The present invention relates to a kind of spray-drying installation and its application processes, belong to mechanical equipment technical field.
Background technology
Microparticle is a kind of small solid particle, and grain size is a kind of microcosmic particle and macroscopical object between 1 ~ 2.5um
The transitional region that body has a common boundary.Since microparticle has quantum size effect, small-size effect, skin effect and macroscopic quantum tunneling
Special nature not available for the conventional solids particle such as effect, so a large amount of new function material has been made using it, it is wide
It is general to be applied to the fields such as chemical industry, medicine, new material and ceramics.Due to microparticle grain size very little, cause the specific surface of microparticle
Product and surface energy sharply increase, and become a unstable thermodynamic system.Thus, easily reunite between microparticle
Phenomenon and so that its grain size is become larger so that losing nano-meter characteristic, reducing its performance in commercial Application.Therefore, micro- is eliminated
Grain reunion, the excellent specific property for keeping microparticle, have great social value.
The reunion of microparticle is broadly divided into soft-agglomerated and hard aggregation.Since Brownian movement and warm-up movement make to generate between microparticle
Collision, by between particle the effects that electrostatic attraction, Van der Waals force, capillary force power formed it is soft-agglomerated.Hydrogen is formed between microparticle
The hard aggregation between microparticle is generated when the chemical reactions such as key, chemical bond, crystal brige.Especially nano ceramics is prepared in hydrothermal synthesis reaction
During particle, when being cleaned and being dried to microparticle, easily reunites between nano-ceramic particle, cause graininess
It can decline.Therefore, it is that processability is excellent to formulate and carry out the efficient anti-agglomeration strategy of cleaning and drying process for microparticle
Microparticle key.
It includes mainly freeze-drying, mechanical crushing method and spray drying process etc. to eliminate the method that microparticle is reunited.Spraying
Seasoning is a kind of physical method, solvent or diluent is atomized the fine droplet that nebulizes first with atomising device, then to misty small liquid
Drop leads to hot-air, during drop and hot air, the moisture in drop is made to be evaporated by rapid vaporization, and final recycling is dry
The process of molecule after dry.The advantages of spray drying process, is, not only can effectively eliminate the reunion between microparticle, and
The original bioactivity of material can also be retained.
According to the analysis to microparticle Agglomeration Mechanism, the reason of spray drying process can eliminate reunion between microparticle, mainly wraps
Include two aspects：First, the atomization process before spray drying increases the distance between microparticle, to eliminate capillary force, keeps away
Exempt from particle to be tightly combined and generate soft-agglomerated；Secondly, in the drying process, the water heat air in drop is kept away by rapid vaporization
Exempt to contact to form hydrogen bond and generate hard aggregation with microparticle due to water.
Although spray drying process can effectively eliminate microparticle reunion, because its atomising device it is bulky, it is complicated,
The shortcomings of at high price and uniformity is poor limits its application and hair in the preparation field of ultra-fine particles especially microparticle
Exhibition.A kind of small spraying drying device is proposed thus, and the atomizer is small, simple in structure, cheap, and it is atomized
It has excellent performance.
Before more than 100 years, with the rise of Dairy Industry, spray-drying installation comes into being, and the spraying of getting up early is dry
Dry device be used to produce milk powder.The research of China's spray-drying installation starts from the seventies in last century.Nowadays, with equipment manufacturing
The development of industry, spray-drying installation are widely used in the fields such as chemical industry manufacture, health care, food industry, ceramic system be standby.Spray
Mist drying device includes mainly three component parts：Atomizer, hothouse, powder recovery.
Invention content
Present invention mainly solves the technical issues of：It is low for existing spray-drying installation efficiency and cannot effectively remove powder
The problem of accumulation, the present invention provides a kind of spray-drying installation and its application processes.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention：
A kind of spray-drying installation, including shell and holder, shell top are connected with nozzle, and inner walls, which are provided with, to be added
Heat pipe, heating tube top have baffle, inner walls to be provided with temperature sensor, and temperature sensor and heating tube are connected with control cabinet
It connects, is in funnel-form below shell, the holder is connected with shell, and vibrator is provided between holder and shell.
A kind of application process of spray-drying installation is：Solvent or diluent is atomized the fine droplet that nebulizes first with atomising device,
It delivers droplets on and shell is injected by nozzle, baffle can prevent drop from spraying into heating tube, while in shell when nozzle sprays
Air is heated in heating tube work on wall, and moisture of the drop after being in contact with hot-air in drop is evaporated by rapid vaporization,
Dry molecule is obtained, the temperature sensor of inner walls detects internal temperature when device works and is transferred to control cabinet,
When temperature is higher or lower than 100~150 DEG C, control cabinet adjusts heating tube temperature, and molecule after drying is attached to shell
When internal wall, the vibrator work between holder and shell is shaken off molecule by shaking, to complete the dry of spraying
It is dry.
The baffle is in 60 ° of angles.
The heating tube is evenly spaced in enclosure interior.
The vibrator shakes when device is stopped.
The beneficial effects of the invention are as follows：
（1）Spray drying process of the present invention is a kind of physical method, and solvent or diluent atomization nebulizes first with atomising device
