Description
Technical field
The utility model relates to spray drying art, particularly relates to a kind of spray dryer shower nozzle.
Background technology
Spraying dry is a kind of method that systematization technique is applied to dry materials.Its operation principle be by solution, suspension or emulsion through atomization after, contact with hot-air or other dry gas in the drying chamber, by solvent or dispersant rapid vaporization, obtain dry products.Its outstanding advantages is rapidly dry, and can directly make solution, emulsion is dried to powdery or particulate preparation, production efficiency is high, and operating personnel are few, and production capacity is large, is one of drier throughput the greater.Spraying dry is easy to adjust, can change operating condition to control the quality index of product, as size distribution, moisture content, biologically active, dissolubility, color etc. in a big way.It is particularly useful for responsive to temperature, can not the material of long-time heating, can realize controlling the pattern of secondary or high order particle simultaneously.
Shower nozzle is one of core component of spray drying device, determines the operational efficiency of equipment and the quality of product to a great extent.Centrifugal sprinkler, pressure type shower nozzle gentle streaming shower nozzle are conventional spraying dry atomising devices.Wherein, pressure nozzle utilizes high pressure to be atomized by material, and misty liquid droplets directly contacts with hot-air, and carry out heat exchange, the short time completes drying.This shower nozzle can obtain less product cut size, but the topography uniformity of powder is bad, and size distribution is wide.Air-flowing type shower nozzle utilizes high velocity carrier gas by the atomization of liquid, has then mixed drying with hot gas.This shower nozzle production capacity is large, but to the pattern of powder and Task-size Controlling not strong.Centrifugal sprinkler is the disk utilizing horizontal direction to make High Rotation Speed is that liquid carrying to be dried supplies kinetic energy, makes it to throw away at a high speed, forms film, filament or drop, by hot gas drying in hothouse.Such shower nozzle obtains the narrow diameter distribution of product, but cannot obtain larger or less meso-position radius.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of spray dryer shower nozzle, can prepare that particle diameter is little, the powder of narrowly distributing.
For this reason, the technical solution of the utility model is as follows:
A kind of spray dryer shower nozzle, comprises atomization impeller, charging ring, high-pressure air inlet device and for driving the main shaft of atomization vane rotary; Described charging ring is arranged at the upper end of described atomization impeller, from upper end to feed in atomization impeller; Described high-pressure air inlet device is arranged on the upside of described atomization impeller, the tube connector comprising admission line, high pressure nozzle and be connected to by described high pressure nozzle on admission line; The position of described high pressure nozzle is just to the discharging opening of described atomization impeller.
Described high pressure nozzle has multiple.
Described tube connector is provided with magnetic valve.For controlling the flow, pulse etc. of high pressure nozzle.
Described tube connector is also provided with universal joint at connection high pressure nozzle place.Universal joint is for adjusting position and the direction of high pressure nozzle.
Described admission line comprises the air inlet pipe and annular gas distributing pipe connected vertically with described air inlet pipe that are parallel to described main shaft.
This spray dryer shower nozzle can realize the powder preparation of small particle diameter, narrow ditribution.
Accompanying drawing explanation
The structure chart of the spray dryer shower nozzle that Fig. 1 provides for the utility model;
The fundamental diagram of the spray dryer shower nozzle that Fig. 2 provides for the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, structure of the present utility model is described in detail.
As shown in Figure 1, a kind of spray dryer shower nozzle, comprises atomization impeller 4, charging ring 2, high-pressure air inlet device and the main shaft 1 for driving atomization impeller 4 to rotate; Charging ring 2 is arranged at the upper end of atomization impeller 4, from upper end to feed in atomization impeller 4; High-pressure air inlet device is arranged on the upside of atomization impeller 4, the tube connector 6 comprising admission line 3, multiple high pressure nozzle 7 and be connected to by high pressure nozzle 7 on admission line 3; The position of high pressure nozzle 7 is just to the discharging opening of atomization impeller 4.Tube connector 6 is provided with magnetic valve 5.For controlling the flow, pulse etc. of high pressure nozzle 7.Tube connector 6 is also provided with universal joint at connection high pressure nozzle 7 place.For adjusting position and the direction of high pressure nozzle.Admission line 3 comprises the air inlet pipe and annular gas distributing pipe connected vertically with described air inlet pipe that are parallel to described main shaft.
During work: material enters atomization impeller 4 from charging ring 2, main shaft 1 drives atomization impeller 4 to rotate, material flies out from the exit of atomization impeller 4, modulation gas sprays through admission line 3, tube connector 6, high pressure nozzle 7, the material that atomization impeller 4 flies out is atomized by gas further that spray from high pressure nozzle 7, forms less drop.By the position regulating the direction of tube connector 6 upper cardan to regulate high pressure nozzle 7; By the temperature of adjustments of gas, the liquid that atomization impeller 4 flies out can be solidified or heats prevapourising, the final object realizing the dry gained morphology microstructure of control and domain size distribution.As shown in Figure 2, in figure, a is the drop (material) that atomization impeller produces, and b is the drop, the drop of partial gasification or the particulate of cryocoagulation that produce after the effect of modulation gas.
Modulation gas adopts normal temperature, high temperature or cryogenic gas.Gas at normal temperature makes atomization impeller 4 disperse the drop produced to disperse further; High-temperature gas, except realizing gas at normal temperature function, can also make dispersant liquid drop pre-vaporized, makes drop be separated into more tiny drop.Drop after dispersion, except realizing gas at normal temperature function, can also solidify by cryogenic gas, dried again after obtaining the solid particle of specific morphology, obtains the product of some special appearance.
