Principles and characteristics of 4A molecular sieve

4A molecular sieve is an alkali metal aluminosilicate capable of adsorbing water, such as NH3, H2S, sulfur dioxide, carbon dioxide, C2H5OH, C2H6, C2H4 and the like having a critical diameter of not more than 4A. Widely used for drying gases, liquids, and also for the purification and purification of certain gases or liquids, such as argon.

Selection recommendation: flash dryer (4A molecular sieve dryer, molecular sieve dryer)

4A molecular sieve special dryer, molecular sieve dryer principle:

Hot air enters the bottom of the dryer tangentially and is driven by the agitator to form a powerful rotating wind field. The slurry enters the dryer through a screw feeder. The material is dispersed by impact, friction and shear under the strong action of a high-speed rotating paddle. The block is quickly comminuted and in full contact with hot air. , heating, drying. The dehydrated dry material rises with the hot gas flow, and the classification ring intercepts the large particles. Small particles are discharged from the center of the ring to the outside of the dryer and are recovered by a cyclone and a dust collector. Dry or loose material is subjected to centrifugal force. , fell to the ground, crushed and dried.

4A molecular sieve special dryer, molecular sieve dryer features:

An organic combination of vortex, fluidization, spray and comminution grading techniques.

The equipment is compact in structure, small in size, high in production efficiency, and can be continuously produced to realize "small equipment and mass production".

It has high dry strength, low energy consumption and thermal efficiency of over 70%.

The material has a short residence time and good finished quality and can be used to dry heat sensitive materials.

Negative pressure or micro-negative pressure operation, good air tightness, high efficiency, and eliminate environmental pollution.
