Dye intermediates dedicated flash dryer
Detailed description
Dye intermediates dedicated flash dryer
Item Description:
dye intermediates, also known as intermediate,
refers to a variety of aromatic derivatives for the production of dyes
and organic pigments. They are aromatic hydrocarbons, benzene, toluene,
naphthalene and anthracene from coal chemical and petrochemical as the
basic raw material, through a series of unit processes of organic
synthesis (see reactions) in the system. With the development of the
chemical industry, has expanded the scope of application of dye
intermediates pharmaceutical industry, pesticide industry, Explosives
industry, information recording materials industry, as well as
additives, surfactants, fragrances, plastics, synthetic fibers and other
production sectors.
Dye intermediates dedicated rotary flash dryer works:
After the beginning, in effect filters ambient air drying system
by the induced draft fan sucked hot air, hot air and steam heat
generated after entering the flash drying machine, and sent through the
screw feeder the drying machine to be dried cake, complete the drying
process of heat and mass transfer in drying machine, gas-solid mixture
is separated by the cyclone and bag filter, the material is separated
from the gas drying system, drying system exhaust, exhaust by the
induced draft fan into the atmosphere.
1, the aircraft completed a cyclone, fluidized, spouted, crushing and winnowing step technologies combine cream and cake-like material capable of drying time for qualified powdered products; compact equipment, covering small size, continuous operation, high production efficiency;
2, high dry strength, low energy consumption, thermal efficiency up to 70%;
3, the residence time is short, good product quality, can be used for drying heat sensitive materials;
4, negative pressure operation, confined good, little environmental pollution.
