摘要:
为了预防蔗糖粉尘爆炸，利用1.2 L哈特曼管研究了NH4H2PO4与Al(OH4对蔗糖粉尘爆炸的抑制作用。在蔗糖粉尘质量分数一定的条件下，通过改变 NH4H2PO4与Al(OH)4的粒径和质量分数，测定其对蔗糖粉尘爆炸的抑制效果。结果表明：随着NH4H2PO4和Al(OH)4质量分数的增加，粒径的减小，蔗糖粉尘的最小点火能均逐渐增大，当惰性粉体增加到一定质量时，蔗糖粉尘被完全惰化，在蔗糖粉尘中分别加入粒径为48~74，38~47，25~37 μm的NH4H2PO4和Al(OH)4，3种粒径的NH4H2PO4使蔗糖粉尘完全惰化的质量分数分别为40%，35%，30%，3种粒径的Al(OH)3使蔗糖粉尘惰化的质量分数均为60%。因此(NH4)H2PO4抑制蔗糖粉尘爆炸的效果比Al(OH)3更显著。
Abstract:
In order to prevent the sucrose dust explosion,the inhibitory effect of NH4H2PO4 and Al(OH)3 on the sucrose dust explosion was studied by using the 1.2 L Hartmann tube. Under the condition of fixed mass fraction of sucrose dust,the particle size and mass fraction of NH4H2PO4 and Al(OH)3 were changed to measure their inhibitory effect on the sucrose dust explosion. The results showed that the minimum ignition energy (MIE) of sucrose dust increased gradually with the increase of the mass fraction and the decrease of particle size of NH4H2PO4 and Al(OH)3. The sucrose dust was completely inert when the inert dust increased to a certain mass fraction. When adding NH4H2PO4 and Al(OH)3 with the particle size of 48~74,38~47 and 25~37 μm into the sucrose dust respectively,the mass fraction of NH4H2PO4 with three particle sizes that made the sucrose dust completely inert was 40%,35% and 30% respectively,while those of Al(OH)3 were all 60%. Therefore,the inhibitory effect of NH4H2PO4 was more significant than Al(OH)3.
