Product details
which produces 10 tons of dry lignin powder a day.Drying tower , a great hollow circle body, is the main space in which hot air separates water from fog material.Since it's size directly affect the working capacity of drying equipment,pulp and paper enterprise could choose relative models of drying equipment according to own production and lignin production. Drying tower consists of a coalfired blast furnace, a multi-tube dust collector or tapered dust collector, ventilation pipes, a cyclone splitter, a high-speed atomizer, a tower crane, a suction fan and a water film scrubber. Drying tower is equipped with a hot air distributor.Hot air distributor inletting wind by using logarithmic spiral form,makes hot air into drying tower steplessly. High-speed centrifugal atomizer is the core device of the drying equipment. High-speed centrifugal atomizer mainly atomizes black liquor whose concentration is about 35% into small particles,which can enlarge the drying surface area and improve the drying rate. The maximum speed of high-speed centrifugal atomizer is 12000-16000R/min. Because of the drying tower using high temperature and hot air, the atomizer is equipped with cooling system and strong lubricating system,which ensure the drying system's normal operation.

The applicance of dring tower makes pulp and paper enterprises completely say goodbye to the pollution of pulp black liquid and it transforms harm into benefit,waste into treasure. The applicance of dring tower can completely control pollution without secondary pollution,which makes the utilization of black liquid realize. The current price of dry lignin powder coming from the black liquid pollution control is about 1800-2400 ¥/t, and the total cost of concentration,drying ,modifying and production is 900 ¥/t or so, in addition, lignin's sales market is very broad, so the economic efficiency is very considerable.
