摘要

传统的除尘系统脱除粗颗粒效率高，而脱除超细颗粒效率非常低，我国燃煤电厂脱除超细颗粒效率无法达到国家标准。湿式相变凝并技术是脱除烟气中超细颗粒的新技术。考虑颗粒性质以及通风因子，改进了超细颗粒凝并长大数学模型。将改进的数学模型写入颗粒群平衡模型中，模拟对比了超细颗粒在管束型相变凝并器和波纹板型相变凝并器内的长大特性及脱除效率。结果表明，两种相变凝并器都能明显提高超细颗粒的脱除效率，但管束型相变凝并器对烟气的冷却效果比波纹板型相变凝并器好。管束型相变凝并器能促进颗粒长大7.71倍，是波纹板型相变凝并器的1.4倍。管束型相变凝并器对颗粒数量浓度脱除效率高达64.7%，而波纹板型相变凝并器对颗粒数量浓度脱除效率为27.2%。

Abstract

The traditional dust removal system has high efficiency in removing coarse particles

but the efficiency of removing ultrafine particles is very low. The efficiency of removing ultrafine particles in China􀆳s coal-fired power plants has not reached the national standard. Wet phase transition agglomeration is the newest technology to remove the fine particles from the flue gas. Considering the particle properties and ventilation factors

the mathematical model for the agglomeration and growth of ultrafine particles is improved. The improved mathematical model is written into the population balance model

and the growth characteristics and removal efficiency of ultrafine particles in the tube bundle type phase-transition agglomerators and the corrugated plate type phase-transition agglomerators are simulated and compared. The results show that both phase-transition agglomerators can obviously improve the removal efficiency of ultrafine particles

but the cooling effect of the tube bundle type phase-transition agglomerators is better than that of the corrugated plate type phase-transition agglomerators. The tube bundle type phase-transition agglomerators can promote particle growth by 7.71 times

which is 1.4 times that of the corrugated plate type phase-transition agglomerators. The removal efficiency of the particle concentration of the tube bundle type phase-transition agglomerator is up to 64.7%

while the removal efficiency of the corrugated plate type phase-transition agglomerator is only 27.2%.
