4. Spray Fluidized Bed Dryer
The spray fluidized bed dryer uses an atomizer to atomize the solution and sprays it into the fluidized bed where the particles move violently. The moisture of the solution itself, the crystallization heat and the heat of the fluidized medium make the water evaporate, crystallize, and dry. Complete in one step. The solution can form granules during the atomization process and at the same time be dried to obtain a granular product. This equipment can be operated intermittently or continuously.
Spray fluidized bed dryers are suitable for sprayable solutions or slurries. This equipment is suitable for drying urea, glucose, sodium bromide, potassium bromide, ammonium bromide, titanium dioxide, sodium malonate, fluorescent whitening agent, potassium acetate, calcium chloride, ammonium nitrate and other materials.
5. Inert particle fluidized bed dryer
The inert particle fluidized bed dryer has the characteristics of evaporating, crystallizing, drying and crushing the material in the same equipment. The fluidized bed is filled with a fluidizable inert carrier having a diameter of several millimeters. The air preheats the carrier and causes the carrier particle group to be in a fluidized state. The material is sprayed onto the surface of the carrier through a nozzle to form a film, and the carrier and the hot air are simultaneously supplied to the material. Conducted heat transfer and convection heat transfer to make it dry.
The equipment is designed according to the principle of spray technology and fluidization technology. It can continuously dry paste or paste materials. It is suitable for titanium dioxide, pesticides, zinc, pigments, dyes, diatomaceous earth, sodium humate, humic acid, etc. The drying of the material.
6. Stirred fluidized bed dryer
Setting up the stirrer at the bottom of a conventional fluidized bed is another type of fluidized drying. It expands the range of materials available for fluidized drying to make it suitable for use as a powdered or granular material that may feed or may agglomerate during dry dehydration. Another benefit of this improvement is that a uniform fluidization can be achieved and the heat and mass transfer intensity can be increased.
The fluidized bed with stirrer is suitable for the drying of materials such as ammonium sulfate, copper sulfate, sodium fluoride, amino acid, anhydride casein, polypropylene resin and phenolic resin.
7. Vibrating fluidized bed dryer
A vibrating fluidized bed dryer is an enhanced special-purpose drying device that is normally used for the final drying of materials. During the drying process, the mechanical vibration assists in the fluidization of the material, which not only contributes to turbulence in the boundary layer, but also enhances heat and mass transfer. It also ensures that the drying equipment operates under fairly stable hydrodynamic conditions.
Vibrating fluidized bed dryer is suitable for the drying of sugar, asbestos minerals, milk powder and other materials.
In addition, there are crushing fluidized bed dryers, internal heat pipe fluidized bed dryers and other types, as well as many special fluidized bed and special fluidized bed, which will not be introduced here.
The device has the following characteristics:
1.Wide application field: the device can regenate various types of activated carbonon by adjusting the angle and rotational speed of furnace pipe.
2.Regeneration activated carbon in the oven retention time 40 minutes, which is applicable to the regeneration levelofall kinds of grain particles, for coal activated carbon also has good regeneration effect.
3.High degree of automation:the device operation achieves automatic control,with man-machine interface+Intelligent instrument control,reduces the operating workers and the labor intensity is low.
4.High recovery rate of Iodine value:basically returned to a new carbon levels above 90%.
5.Low carbon loss:≤1-2%(Coal carbon)But slightly higher than the JHR-O series activated carbon fuel diesel reclamation equipment
6.Easy installation, covers an area slightly larger, but the small space height requirements, large installed power.
Long service life:The core components furnace tube using thick wall (10 mm thick) 1200 ℃ high temperature resistance, corrosion resistant special stainless steel pipe.
