Scheme of process flow and working principle:

气流式喷雾，又称二流体喷雾，料液由雾化器出料口流出，压缩空气从雾化器的气环口高速喷出(气速达200米/秒以上)，当二者在端面接触时，由于二者存在很大相对速度，所产生的高摩擦力及剪切力将料液雾化，并同干燥塔内的热空气进行接触后得到干燥，成品细粉则随气流进入旋风分离器进行气固分离，空气经袋滤器除尘后由引风机引出。

公司研制的三流式雾化器对高粘度、膏状、胶状物均有较好的雾化效果。

Airflow spraying, also called 2 fluid spraying, liquid material is flowed out from outlet of atomizer, and the compressed air is sprayed out in high speed (200m/s) from air ring vent of atomizer, when they touch with each other at the end side, high friction force and shearing force incurred atomize the liquid material as a result of larger relative speed, which is dried after touching with hot air inside the drying tower, finished fine powders enter into cyclone separator along with airflow for gas-solid separation, and the air is output by draught fan after filtering by bag filter.

3 fluid atomizer developed by our company has better atomizing effect for high viscosity, pasty and colloid materials.

（密闭循环式气流喷雾干燥设备工艺简介）

氮气先充盈入密闭式干燥设备系统中，被加热后（非空气）对物料进行烘干作业（原理同敞开式干燥设备系统干燥过程相类似）。烘干后的物料随气流进入旋风除尘器内进行气固分离；尾气进入离线式布袋除尘器内进行过滤除尘；再由引风机鼓入洗涤塔内进行洗涤。洗涤塔内的尾气进入冷凝除湿器内进行冷却、除湿；再被散热器加热重新进行烘干作业。
