噴霧(wu)除塵原理(li):

向(xiang)塵(chen)(chen)(chen)(chen)(chen)(chen)源噴(pen)(pen)(pen)(pen)射(she)(she)水(shui)霧(wu)(wu)(wu)(wu)(wu)，使塵(chen)(chen)(chen)(chen)(chen)(chen)粒濕潤(run)、增重(zhong)，并(bing)從氣(qi)(qi)流(liu)中沉降的(de)(de)(de)過程(cheng)。噴(pen)(pen)(pen)(pen)霧(wu)(wu)(wu)(wu)(wu)降塵(chen)(chen)(chen)(chen)(chen)(chen)多(duo)用(yong)(yong)于巖礦裝載、轉(zhuan)運、卸(xie)料(liao)點及礦井風(feng)(feng)源凈化。噴(pen)(pen)(pen)(pen)霧(wu)(wu)(wu)(wu)(wu)降塵(chen)(chen)(chen)(chen)(chen)(chen)效(xiao)率與(yu)霧(wu)(wu)(wu)(wu)(wu)滴粒徑(jing)(jing)、噴(pen)(pen)(pen)(pen)霧(wu)(wu)(wu)(wu)(wu)體中霧(wu)(wu)(wu)(wu)(wu)滴密度(du)、霧(wu)(wu)(wu)(wu)(wu)滴與(yu)塵(chen)(chen)(chen)(chen)(chen)(chen)粒的(de)(de)(de)相對運動(dong)速度(du)、粉塵(chen)(chen)(chen)(chen)(chen)(chen)粒徑(jing)(jing)和性質等因(yin)素(su)有(you)關。霧(wu)(wu)(wu)(wu)(wu)滴粒徑(jing)(jing)過大會(hui)很快沉降，過小容易蒸發(fa)，且易被(bei)(bei)風(feng)(feng)流(liu)帶走，兩者均不利于捕塵(chen)(chen)(chen)(chen)(chen)(chen)。霧(wu)(wu)(wu)(wu)(wu)滴粒徑(jing)(jing)約為(wei)(wei)塵(chen)(chen)(chen)(chen)(chen)(chen)粒直(zhi)(zhi)徑(jing)(jing)的(de)(de)(de)150倍時，捕塵(chen)(chen)(chen)(chen)(chen)(chen)效(xiao)果(guo)較佳。塵(chen)(chen)(chen)(chen)(chen)(chen)粒與(yu)霧(wu)(wu)(wu)(wu)(wu)滴間的(de)(de)(de)相對運動(dong)速度(du)愈(yu)大。慣性碰(peng)撞愈(yu)劇烈(lie)，碰(peng)撞效(xiao)率愈(yu)高。霧(wu)(wu)(wu)(wu)(wu)滴粒徑(jing)(jing)大于1的(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)(chen)粒，這兩種捕塵(chen)(chen)(chen)(chen)(chen)(chen)機理都起(qi)作(zuo)用(yong)(yong)。細微塵(chen)(chen)(chen)(chen)(chen)(chen)粒表面吸附(fu)著氣(qi)(qi)膜層，需以較大的(de)(de)(de)能(neng)量才能(neng)被(bei)(bei)沖(chong)破，故難以被(bei)(bei)霧(wu)(wu)(wu)(wu)(wu)滴捕集。因(yin)此，噴(pen)(pen)(pen)(pen)霧(wu)(wu)(wu)(wu)(wu)對呼吸性粉塵(chen)(chen)(chen)(chen)(chen)(chen)的(de)(de)(de)捕獲效(xiao)率很低。為(wei)(wei)提高水(shui)霧(wu)(wu)(wu)(wu)(wu)的(de)(de)(de)降塵(chen)(chen)(chen)(chen)(chen)(chen)效(xiao)果(guo)。 噴(pen)(pen)(pen)(pen)霧(wu)(wu)(wu)(wu)(wu)系統的(de)(de)(de)水(shui)力性能(neng)與(yu)噴(pen)(pen)(pen)(pen)霧(wu)(wu)(wu)(wu)(wu)體結(jie)構(gou)有(you)關，常(chang)用(yong)(yong)霧(wu)(wu)(wu)(wu)(wu)滴分散度(du)、噴(pen)(pen)(pen)(pen)霧(wu)(wu)(wu)(wu)(wu)體的(de)(de)(de)霧(wu)(wu)(wu)(wu)(wu)滴密度(du)、耗(hao)水(shui)量和水(shui)壓等參數(shu)表示。其參數(shu)有(you)：(1)射(she)(she)程(cheng)。水(shui)從噴(pen)(pen)(pen)(pen)霧(wu)(wu)(wu)(wu)(wu)器噴(pen)(pen)(pen)(pen)出口(kou)起(qi)霧(wu)(wu)(wu)(wu)(wu)滴作(zuo)直(zhi)(zhi)線(xian)運動(dong)段(duan)的(de)(de)(de)水(shui)平(ping)距離。在(zai)射(she)(she)程(cheng)內的(de)(de)(de)霧(wu)(wu)(wu)(wu)(wu)滴動(dong)能(neng)大，捕塵(chen)(chen)(chen)(chen)(chen)(chen)效(xiao)果(guo)好。(2)作(zuo)用(yong)(yong)長(chang)度(du)。直(zhi)(zhi)線(xian)運動(dong)段(duan)后，霧(wu)(wu)(wu)(wu)(wu)滴在(zai)重(zhong)力作(zuo)用(yong)(yong)下呈拋物線(xian)運動(dong)，霧(wu)(wu)(wu)(wu)(wu)滴動(dong)能(neng)減弱，捕塵(chen)(chen)(chen)(chen)(chen)(chen)效(xiao)果(guo)也減弱。從噴(pen)(pen)(pen)(pen)霧(wu)(wu)(wu)(wu)(wu)器出口(kou)至(zhi)完成拋物線(xian)運動(dong)的(de)(de)(de)水(shui)平(ping)距離稱為(wei)(wei)作(zuo)用(yong)(yong)長(chang)度(du)。(3)噴(pen)(pen)(pen)(pen)射(she)(she)體擴張角。擴張角大，噴(pen)(pen)(pen)(pen)灑面積大，捕塵(chen)(chen)(chen)(chen)(chen)(chen)面大。

噴(pen)霧除塵設備特(te)點(dian)：

（1）主控(kong)器的(de)傳動(dong)輪一旦(dan)轉動(dong)，其殼體內(nei)所(suo)裝的(de)供水閥立即自動(dong)打開，自控(kong)器開始工作。傳動(dong)輪停止轉動(dong)時，閥門自動(dong)關閉(bi)。機械(xie)原理(li)的(de)控(kong)制(zhi)器，不需要專設傳動(dong)電源，因(yin)而具有防火、防爆性能，安全可靠(kao)。

（2）該系統(tong)是由(you)皮帶或其他運輸設(she)備(bei)帶動，自控器(qi)供水(shui)閥(fa)門的打開(kai)大小正好與(yu)運輸設(she)備(bei)的負(fu)荷(he)情況*，能(neng)夠自動控制噴(pen)(pen)霧量，避免了(le)噴(pen)(pen)霧量過多而引(yin)起的皮帶“打滑”現象(xiang)，同時也節約了(le)水(shui)資源；

（3）通過(guo)主(zhu)控器(qi)安裝高度(du)的調節，能夠保證只有皮(pi)(pi)帶(dai)“載(zai)重”運(yun)行時，水(shui)(shui)才噴到待運(yun)物料上。若(ruo)皮(pi)(pi)帶(dai)停止運(yun)轉或“空載(zai)”運(yun)轉，主(zhu)控器(qi)立即切(qie)斷水(shui)(shui)源。
