設備特點

●干燥速度快，料液經霧化后表面積大大增加，在熱風流中，瞬間就可蒸發95-98%的水份，完成干燥的時間僅需十幾秒鐘到數十秒鐘，特別適用于熱敏性物料的干燥。

●所得產品為球狀顆粒，粒度均勻，流動性好，溶解性好，產品純度高，質量好。

●使用范圍廣，根據物料的特性，可以用熱風干燥，也可用冷風造粒，對物料的適應性強。

●操作簡單穩定，操作方便，容易實現自動化作業。

Characteristics equipment

●Drying is fast. Liquid materials are atomized with surface area greatly increased in the hot air so that 95%-98% of moisture can be evaporated instantaneously. The drying will be completed in a few seconds, which makes it especially suitable for drying heat sensitive materials.

●The products are ball granules, with high purity and good quality thanks to their good uniformity, mobility and solubility.

●It has a wide application range. It can make use of hot air drying or cold air granulating according to the characteristics of materials. It is highly adaptable to different materials.

●Relying on the simple, stable and convenient operation, it is easy to realize the automatic operation.

概述

本機組是一種可以同時完成干燥和造粒的裝置。按工藝要求可以調節料液泵的壓力流量、噴孔的大小、得到所需的按一定大小比例的球形顆粒。

本機組工程過程為：料液通過隔膜泵高壓輸入，噴出霧狀液滴，然后同熱空氣并流下降，大部分粒由塔底排料口收集，廢氣及其微小粉末經旋風分離器分離，廢氣由排風機排出，粉末由設在旋風分離器下端的收粉筒收集，風機出口處還可裝備二級除塵裝置，回收率在96-98%以上。

與物料接觸部分的塔體、管道、分離器的材料，均采用SUS304制作。在塔體內部與外殼之間有足夠的保溫層，填充材料為超細玻璃棉，塔體設有觀察門、視鏡、光源及控制儀表、由電器控制操作臺控制和顯示。

熱源裝置采用蒸汽加熱或電加熱器，具有操作方便、啟動快、結構緊湊、熱風干凈清潔等優點。另外在電氣控制柜內裝有電加熱器的控制調節裝置，使進口溫度無級調節。對于缺電地區可采用蒸汽加熱或燃煤、燃油熱風爐等方式，局部或全部代替電加熱裝置。本廠可以根據用戶的實際需要提供不同的加熱方式。

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.
