摘　　要：设计了一种黑液汽化联合纸幅干燥的方案，设备包括黑液汽化系统和纸幅热风干燥系统两部分。其工艺流程是黑液在汽化炉内汽化，经过冷却和脱硫处理，得到净化汽化气。净化汽化气燃烧产生热量，给炉内气体加热，得到温度230～240~C的热风；热风经过热风罩，吹向烘缸表面的纸幅，加快纸幅的干燥速率。Using black liquor gasification gas to substitute a part of fuel for paper sheet drying could save the cost of fuel and increase eco- nomic efficiency and competitiveness of the enterprise. A design scheme of black liquor gasification combined with paper sheet drying was formulated in this paper. The equipments of the project consisted of black liquor gasification system and paper drying system. The technologi- cal process was designed as the follows：the gasification gas was produced in the gasifer, and consequently treated with cooling and desulfu- rization, thereby the purified gasification gas was obtained. The purified gas could be burned as fuel in furnace to heat up the air to 230 - 240℃. Then the hot air was blown to the wet sheet on the surface of dryer via a heated-air hood to increase drving rate of the naner sheet.
