【摘要】：對(duì)某鋼鐵企業(yè)燒結(jié)工序不同煙粉塵排放源的現(xiàn)場(chǎng)采樣,包括燒結(jié)煤粉破碎、燒結(jié)配料、燒結(jié)機(jī)頭、燒結(jié)機(jī)尾和燒結(jié)礦成品篩分等工藝過(guò)程.測(cè)試了各工藝過(guò)程的除塵灰以及排放煙粉塵的粒徑分布和化學(xué)組成,分析得出除塵前煙粉塵的粒徑分布和化學(xué)組成.在此基礎(chǔ)上,建立了燒結(jié)工序各個(gè)煙粉塵排放點(diǎn)的綜合評(píng)價(jià)指標(biāo).通過(guò)專家調(diào)研得出了各個(gè)評(píng)價(jià)指標(biāo)的權(quán)重集,最終運(yùn)用模糊綜合評(píng)判法,對(duì)燒結(jié)工序各個(gè)煙粉塵排放點(diǎn)進(jìn)行綜合評(píng)價(jià),得出燒結(jié)工序的重點(diǎn)煙粉塵排放點(diǎn).結(jié)果表明,燒結(jié)機(jī)頭的TSP排放總量、PM_(2.5)質(zhì)量分?jǐn)?shù)、PM_(10)質(zhì)量分?jǐn)?shù)和重金屬元素質(zhì)量分?jǐn)?shù)均為最大,是燒結(jié)工序最重要的煙粉塵排放點(diǎn).
[Abstract]:The field sampling of different smoke and dust emission sources in sintering process of a iron and steel enterprise includes sintering pulverized coal crushing, sintering proportioning, sintering machine head, sintering machine tail and sinter product sieving, etc. The particle size distribution and chemical composition of dust removal and smoke dust emission in each process were measured and the particle size distribution and chemical composition of smoke dust before dust removal were obtained. On this basis, the comprehensive evaluation index of smoke dust emission points in sintering process is established. Through expert investigation, the weight set of each evaluation index is obtained. Finally, the comprehensive evaluation of each smoke dust emission point in sintering process is carried out by using fuzzy comprehensive evaluation method, and the key smoke dust emission points in sintering process are obtained. The results show that the mass fraction of tsp and heavy metal elements in the sinter head is the largest, which is the most important emission point of smoke dust in sintering process.
