摘要:
采用自制的煤大样量吸附实验装置测定了常温常压条件下煤对每种烟道气体成分 的饱和吸附量,并根据电厂烟气流量与工作面配风量的计算对井下注入烟气的安全性进 行了分析。实验数据结果显示,煤是一种多孔性物质,将电厂烟气注入井下采空区,每 吨煤可封存烟气中CO2约1.2 m3, N2约0.26 m3,其中烟气中SO2和NO2可全部被煤样封 存,揭示了利用烟气替代传统N2及CO2预防煤炭自燃的可行性;根据对电厂烟气流量及 回采工作面配风量的计算发现,在假定注入采空区的烟气与煤、岩没有任何吸附的情况 下,按照规定流量注入烟气未造成工作面回风巷中CO2、SO2气体浓度超标,NO2则超出 规定允许最高浓度,因此应对注入井下的烟气进行进一步脱硝处理。
Abstract:
By using the self-made absorption experimental device of coal with large sample quantity, the saturated adsorption quantities of coal on each kind of smoke component under normal temperature and pressure conditions were measured, and the safety of injecting smoke into underground goaf was analyzed by calculating the flow of power plant smoke and the air volume of working face. The experiment results showed that coal is a porous substance, when injecting the power plant smoke into underground goaf, about 1.2 m3 CO2 and 0.26 m3 N2 could be sealed in per ton of coal, and all the SO2 and NO2 in the smoke could be sealed in coal sample, which revealed the feasibility of using smoke instead of traditional N2 and CO2 for preventing spontaneous combustion of coal. According to calculation on the flow of power plant smoke and the air volume of working face, when assuming that no smoke injected into goaf could be absorbed by coal or rock, the concentration of CO2 and SO2 in the air return way of working face would not exceed the standard when injecting smoke at the regulated flow, while the concentration of NO2 would exceed the maximum concentration that can be allowed, so the smoke injected into underground goaf should be denitrated further.
