一种正压式低倍数泡沫发生装置的研发
|
摘要
开展灭火实验,对比正负压泡沫发生装置的灭火效果。通过泡沫发泡倍数和析液时间等泡沫稳定性测试,优化了正压式泡沫发生装置结构。通过引入SK静态混合器作为扰流装置完成正压同轴混合腔的优化。结果表明,正压式泡沫发生装置灭火效果优于负压式泡沫发生装置;同轴混合腔发出泡沫性能参数优于T型混合腔。通过优化正压发生装置混合腔体结构和扰流装置,提升了低倍数泡沫灭火剂发泡性能参数。
Fire extinguishing experiment was carried out, to compare the fire extinguishing effect of positive and negative foam generator. By stability test such as foam expansion and drainage time,the structure of the positive foam generator was optimized. Using SK static mixer as the spoiler, the positive coaxial mixing cavity was optimized. Results showed that, the fire extinguishing effect of positive foam generator is better than that of the negative foam generator; the foam generated by coaxial mixing cavity is better than that generated by T type mixing cavity. By optimizing the mixing cavity structure and spoiler, the foaming parameters of low-expansion foam agent were improved.
