设备特点

　　<干燥速度快，料液经雾化后表面积大大增加，在热风流中，瞬间就可蒸发95-98%的水份，完成干燥的时间仅需十几秒钟到数十秒钟，特别适用于热敏性物料的干燥。

　　<所得产品为球状颗粒，粒度均匀，流动性好，溶解性好，产品纯度高，质量好。

　　<使用范围广，根据物料的特性，可以用热风干燥，也可用冷风造粒，对物料的适应性强。

　　<操作简单稳定，操作方便，容易实现自动化作业。

　　概述

　　本机组是一种可以同时完成干燥和造粒的装置。按工艺要求可以调节料液泵的压力流量、喷孔的大小、得到所需的按一定大小比例的球形颗粒。

　　本机组工程过程为:料液通过隔膜泵高压输入，喷出雾状液滴，然后同热空气并流下降，大部分粒由塔底排料口收集，废气及其微小粉末经旋风分离器分离，废气由排风机排出，粉末由设在旋风分离器下端的收粉筒收集，风机出口处还可装备二级除尘装置，回收率在96-98%以上。

　　与物料接触部分的塔体、管道、分离器的材料，均采用SUS304制作。在塔体内部与外壳之间有足够的保温层，填充材料为超细玻璃棉，塔体设有观察门、视镜、光源及控制仪表、由电器控制操作台控制和显示。

　　热源装置采用蒸汽加热或电加热器，具有操作方便、启动快、结构紧凑、热风干净清洁等优点。另外在电气控制柜内装有电加热器的控制调节装置，使进口温度无级调节。对于缺电地区可采用蒸汽加热或燃煤、燃油热风炉等方式，局部或全部代替电加热装置。本厂可以根据用户的实际需要提供不同的加热方式。

　　Descriptions

　　The unit is an apparatus that can finish drying and granulating at

　　the same time. The needed ball granules with certain size and ratio can be

　　achieved in accordance with process requirements by adjusting pressure flow and

　　size of holes.

　　The working process of the unit is as follows: The liquid materials

　　are pumped through high pressure by the diaphragm pump, and atomized into small

　　drops, then fall with hot air concurrently. Most of the powders will be

　　collected through the discharge outlet at the bottom of the tower. The waste

　　gas and fine powders will be separated through the cyclone. The waste gas will

　　be discharged through the exhaust fan and the powders will be collected by the

　　powder collector at the bottom of the cyclone. At the outlet it can also be

　　equipped with the secondary dust collector. The recovery rate will be over

　　96%-98%.

　　The tower body, pipe and separator that contact raw materials are

　　made of SUS304. There are enough heat insulation layers between the inner and

　　outer of the tower body. The filler is ultra-fine glass fiber. The tower body

　　is also equipped with observation door, sight glass, light source and control

　　instruments, which are controlled and displayed through the electric control

　　panel.

　　The heat source set may be steam or electric heater. It has such

　　features as convenient operation, quick starting, compact structure, clean hot

　　air and so on. Moreover, the control device installed with electric heater

　　inside the electric control cabinet realizes stepless regulation of the inlet

　　temperature. The steam heating, coal-burning or oil-burning hot blast furnace

　　can be applied to places where there is a shortage of electricity to replace

　　electric heating locally or fully. Our factory can provide different heating

　　methods according to actual requirements of users.
