装满木制弦形格子的洗苯塔内起火原因,一是外部火焰触到要害部位,二是停工检查和更换格子时硫化铁自燃。洗苯塔内存在起火爆炸的危险性,还因为弦形格子是用松木条制成(松木燃烧温度为225℃,最高燃烧温度为900℃,发热量达17兆焦耳/公斤)。在生产过程中,木格子被有一定温度的煤气包围着,而且木格子表面又粘有占总 Filled with wooden chord-shaped washing benzene tower cause of the fire, one is the outer flame hit the key parts, the second is to stop work to check and replace the lattice pyrophosphoric spontaneous combustion. There is also the danger of a fire exploding in the benzene column because the chordal grid is made of pine strips (pine burning at 225 ° C with a maximum combustion temperature of 900 ° C and a heat output of 17 mJ / kg). In the production process, the wooden lattice is surrounded by gas with a certain temperature, and the surface of the wooden lattice is glued with the total
