Gas-phase method white carbon black deacidification system

The utility model provides a white carbon black deacidification system adopting a gas phase method. The system comprises a first deacidification furnace, a second deacidification furnace, a separatorand a heater, steam is heated to about 250 DEG C through a heater, then the heated steam is introduced into two deacidification furnaces, the steam and white carbon black are sequentially mixed in thetwo deacidification furnaces for deacidification, then the white carbon black and hot air are further deacidified in a separator, and finally the pH value of the white carbon black is stabilized to be 4.2 or above. 本实用新型提供了一种气相法白炭黑脱酸系统。该系统包括第一脱酸炉、第二脱酸炉、分离器和加热器，通过加热器将蒸汽加热至250℃左右，再将加热后的蒸汽通入到两个脱酸炉中，使蒸汽与白炭黑依次在两个脱酸炉中混合进行脱酸，然后使白炭黑和热空气在分离器中进一步脱酸，最终使得白炭黑pH值稳定在4.2以上。
