Useful effect
1. energy consumption aspect: old technology uses what power-equipment produced steam to heat concentration response still, belong to and heat source re chloride is provided indirectly, energy consumption is bigger, and spraying dry uses the Sweet natural gas heat gas blower produced that directly burns hot blast blows the vaporific re chloride of convection drying in drying tower to make re chloride instantaneous crystallization form crystalline powder, reduce the energy consumption of major part.
2. production cycle aspect: the rare earth chloride solution after production time contrast old technology is concentrated, need the cooling through the long period, additional artificial pulverizing packs, production cycle is longer, novel process directly forms dry powder, feed opening is directly packed and is eliminated temperature-fall period, produces one ton of rare earth chloride and saves about 6 hours.
3. turnout aspect: process yields contrast spray-drying tower day output can reach 18 tons, and old-fashioned condensing crystal day output is 10 tons
4. consuming artificial aspect: the crystallization that the rare earth chloride of concentration is formed after lowering the temperature needs artificial carrying out to pulverize, what the rare earth chloride of spray-drying tower process was formed is that powdery product does not need artificial pulverizing
5. the apparent aspect of product: the rare earth chloride of concentration block size after artificial pulverizing is uneven, and packaging is inconvenient, and the product that spray-drying tower is produced belongs to the easy appearance uniform of powder packaging.
