Ammonium Chloride Drying Technology

Ideal Choice for Ammonium Chloride Drying Equipment

Ammonium chloride is the ammonium salt of hydrochloric acid, mostly a by-product of the soda industry. Ammonium chloride is an excellent nitrogen fertilizer. The dried ammonium chloride is not easy to agglomerate, which is convenient for transportation, storage and use. It has a competitive advantage in the market. The production of dry ammonium chloride is the future development direction.

The drying of ammonium chloride is one of the main processes in the production of combined-soda process. The development directions of ammonium chloride drying process are as follows:

The emission of exhaust gas after drying should reach the emission standard and be minimized as possible;

Reducing steam consumption and electricity consumption, thereby reducing operating costs; Large-scale equipment and high automation;

Stable operation of equipment and corrosion resistance.

The steam rotation process uses mechanical transmission to provide power guarantee for drying heat exchange. It does not require a large amount of fluidized medium. It has a small amount of exhaust gas after drying, low installed power, obvious energy saving effect, and lower pressure for exhaust gas treatment .

The Annular Tube Split Type Steam Rotary Dryer of Shandong Tianli Energy Co., Ltd. is an ideal choice for large-scale (annual output of 200,000 tons / ton and above) ammonium chloride drying equipment. The steam rotary dryer is a rotary equipment that uses the heat of steam to dry materials through indirect heat exchange. The heat exchange tube in the dryer cylinder rotates with the cylinder body, and the material entering the dryer is lifted and stirred by the heat exchange tube in the cylinder body, and is dried by the heat provided by the heat exchange tube. The dried product moves from the higher end to the lower end by the inclination of the dryer, and is discharged from the discharge port at the lower end, and the moisture-carrying gas is discharged by the induced draft fan after purifying and dedusting. During the drying process, the material is in sliding contact heat exchange with the entire circumferential surface of the annular tubes with the rotation of the dryer. The contact method between the annular tubes and the material is the co-current full-area sliding contact heat exchange.

The Annular Tube Split Type Steam Rotary Dryer of Tianli Energy has the following characteristics:

1) More annular tubes per unit volume, larger heat exchange area;

2) The heat exchange tube components are easy to disintegrate, and each group of heat exchange tube components can be withdrawn separately from the feed end, which is convenient for maintenance and replacement;

3) The spacing of the heat exchange tubes is adjustable, which effectively improves the material flow state at the feed end;

4) The material and the annular tubes are in co-current contact, which can effectively reduce the wear of the material particles on the heat exchange tubes, especially suitable for highly abrasive materials, which greatly improves the service life of the heat exchange tubes;

5) The equipment runs stably and is suitable for continuous production. It can run continuously for 8000 hours annually.
