蜗壳式热风分布器的设计及注意事项

The Design of Volute Hot Air Distributor and the Matters Needing Attention

热风进入蜗壳式分布器后呈旋转状态进入干燥塔与雾化料液进行热与质的交换,与高速旋转的离心机转向相反。由于采用高速离心雾化器雾化料液而非高压啧嘴,因此,其热风分布器的结构为蜗壳式结构,与压力喷雾干燥塔所使用的分布器不同。这种分布器结构比较复杂,操作也比较繁琐,如果分风不均、结构不尽合理,极易在塔顶出现焦粉等现象,严重时还会影响产品的质量。本文仅以RGYP01-500型立式离心喷雾干燥塔在奶粉生产中的设计及应用加以阐述。

after the hot air into the volute distributor in rotating state into the drying tower and atomization heat exchange between the quality and material liquid, with high-speed centrifuge to instead. Due to high-speed centrifugal atomizer atomized liquid instead of using high pressure spray nozzle, therefore, the structure of hot air distribution and pressure spray drying tower is used by the distributor of the structure is different, it USES is the structure of the volute. The distributor structure is more complex, the operation is more troublesome, if the wind is uneven, some unreasonable structure easy to appear in the top of the tower the phenomenon such as coke powder, serious when can also affect the quality of the products. Only RGYP01-500 type vertical centrifugal spray drying tower design and application in the production of milk powder.
