The flash drying equipment is a kind of airflow drying equipment system with no torsion damage. It is inorganically connected with fluidization, swirling, spouting, destruction and grading. It is a fluidized craft, swirling craft, and spray. A combination of craftsmanship and degradation of the spread of thermal art for drying moisture outside the material.
The wet material is separated into the heated gas stream by the dry air duct of the flash drying equipment, and drying takes place for a few seconds. Flash drying equipment has not been used in many industries, including food, chemicals, minerals and polymers. The combination of materials is also common, including powder, lumps, granules, flakes, pastes, gels and Both slurries and the like are possible (reverse mixing of dry and wet materials is necessary when handling slurries, pastes or viscous materials). The flash drying equipment is one of the popular drying equipments for the growing use of the category Zui. The domestic flash dryer is also called the cyclone dryer and the torsion quick dryer.
The flash drying equipment is typical of fluidized drying, which not only realizes the continuous operation of dynamic drying, but also reduces the static failure of static dry heat, labor intensity, pollution and extravagance, so that the chemical products are drying units. It is effective to achieve the same effect, quantity, efficiency and perfection.
The technical advantage and specific application of the polyaluminum sulphate flash dryer are as follows: the slave body of the flash drying equipment is a square tubular drying chamber, which is composed of the bottom fluidized section, the external drying section and the top section. Material destruction, drying, grading, etc. Others include heaters, feeders, agitation rupture systems, classifiers, drying tubes, cyclone breakouts, baghouses, and fans. After the natural air is heated and removed by heating, the air inlet of the flash drying equipment enters the stirring and breaking drying chamber from the bottom of the dryer at a suitable blowing speed, and spirally rises. At the same time, the material is quantitatively inserted into the tower by the feeder, and the heat is taken. The air is enriched and heat exchanged, and the material is strongly sheared, blown, and torsed. Therefore, the material is micro-materialized by centrifugation, shearing, bumping, and friction, and the heat transfer is enhanced.
At the bottom of the flash drying equipment, the larger and drier pellets are mechanically broken under the action of the agitator, and the particles with lower moisture content and smaller particle size are entrained by the airflow, and are further dried outside the rising process. After refining, the dried product is discharged through a cyclone splitter, and the dust-containing exhaust gas is discharged into the atmosphere by the pulse bag filter. Flash drying equipment has the following significant advantages over other drying equipment:
1. The flashing drying equipment selects a special feeder, and the feeding of the joint is constant, and there is no bridging, arching or clumping phenomenon, especially for viscous materials.
2, because the drying time is short, the material takes hot air relatively high speed and zui hot air does not take indirect contact with the dry material, so the use of heat sensitive materials.
3. The inner cone layout at the bottom of the drying chamber, the scouring of the airflow to the wall and the strange layout of the agitator determine the material that the flash drying equipment can handle.
4. Because the materials outside the drying process are broken, washed, and bumped, the profile is large and the drying is strengthened, and the drying strength of the flash drying equipment is higher.
5. Set the internal discharge (swirl, ceramics or classifier) ​​in the drying tower, and take the same coordination of the inlet and outlet temperatures. The flash drying equipment ineffectively controls the final moisture and fineness of the material.
6. The bottom of the drying chamber is provided with a water partition to cool and disassemble, which avoids the phenomenon that the material is in the high temperature zone at the bottom.
7. The indoor air velocity in the drying chamber is high, the material staying time is short, and the invalid anti-wear material sticking wall and heat sensitive material variables are invalid.
8. The flash drying equipment is operating under the micro-negative pressure mode, eliminating the pollution, and adopting different dust removal methods and dust removal materials according to the divergent materials (pulse bag type dust collector, water bath dust collector, venturi wet dust collector) Wait). If the work is done clean and environmentally friendly.

Advantages of flash drying equipment
1. The indoor air velocity in the drying chamber is high, and the material residence time is short, which effectively prevents the material from sticking to the wall and the heat sensitive material from deteriorating, and can be dried into a uniform powder product at one time, eliminating the steps of crushing and sieving.
2. The drying chamber is equipped with a classification ring and a swirling sheet, and the material fineness and final moisture are adjustable. The special air separation device reduces the resistance of the equipment and effectively improves the uniformity of the material.
3. The special cooling device and air pressure sealing device are installed at the bottom of the dryer to avoid the deterioration of the material in the high temperature zone at the bottom.
4. It can effectively control the final moisture and fineness. Through the adjustment of feeding, hot air temperature and classifier, the moisture content and fineness of the product are guaranteed to be uniform.
5. The flash dryer has the advantages of fast drying speed, high efficiency, greatly shortened drying cycle and reduced energy consumption.
6. The size of the flash dryer is small, easy to install and maintain. 7. The industrial quality of the flash dryer is good, compared with the conventional method.
8. Flash dryer saves energy, reduces consumption, improves industrial quality, safety and hygiene,
