高壓干霧噴霧降塵車

煤(mei)塵(chen)是(shi)煤(mei)礦井下(xia)危(wei)害(hai)(hai)性(xing)zui大的(de)自(zi)然災害(hai)(hai)之一，工人(ren)(ren)吸入礦塵(chen)，輕則患呼(hu)吸道炎癥，重則患塵(chen)肺(fei)病。我(wo)國煤(mei)礦每年因塵(chen)肺(fei)病死亡的(de)人(ren)(ren)數(shu)遠遠超過直接由井下(xia)生產性(xing)事故死亡的(de)人(ren)(ren)數(shu)，且絕大多數(shu)礦井的(de)煤(mei)塵(chen)爆炸危(wei)險性(xing)都比較強，煤(mei)塵(chen)爆炸事故也時(shi)有發生。

粉塵監控噴霧降塵控制系統
噴(pen)(pen)霧系統(tong)(tong)可以實(shi)現(xian)對煤礦(kuang)產塵(chen)(chen)作業場所粉(fen)塵(chen)(chen)濃度的(de)實(shi)時(shi)(shi)監(jian)測及(ji)降(jiang) 除。該系統(tong)(tong)由粉(fen)塵(chen)(chen)濃度傳感器測定(ding)粉(fen)塵(chen)(chen)濃度、粉(fen)塵(chen)(chen)噴(pen)(pen)霧控(kong)制器自(zi)動控(kong) 制噴(pen)(pen)霧降(jiang)塵(chen)(chen)系統(tong)(tong)的(de)開停，視頻監(jian)控(kong)利用原有煤場安裝(zhuang)的(de)監(jian)控(kong)攝像儀， 實(shi)現(xian)對所測場所粉(fen)塵(chen)(chen)的(de) 24 小(xiao)時(shi)(shi)連(lian)續監(jian)測、監(jian)控(kong)及(ji)灑水降(jiang)塵(chen)(chen)，并可通(tong) 過網絡與市監(jian)控(kong)平(ping)臺(tai)進行數據傳輸。

利用噴霧(wu)產(chan)生(sheng)的(de)微粒由于其及其細小，表面張力基本上(shang)為(wei)零，噴灑到空(kong)氣(qi)中能迅速吸附空(kong)氣(qi)中的(de)各(ge)種(zhong)大(da)小灰塵顆粒，形成有(you)效控塵。對大(da)型開闊范圍的(de)控塵降塵有(you)很好的(de)效果(guo)(guo)。同時這種(zhong)效果(guo)(guo)*是(shi)一種(zhong)霧(wu)化效果(guo)(guo)，絕不產(chan)生(sheng)水滴和潮濕。特別適用于鑄造廠、紡(fang)織廠、食品廠、印刷廠、機場、游樂場、步行街等廣泛應用，費用低(di)廉(lian)效果(guo)(guo)明(ming)顯。

濕潤型化學抑塵劑由(you)一種或(huo)多種表面(mian)活性劑組成，是由(you)親(qin)水(shui)(shui)(shui)基(ji)和(he)疏(shu)水(shui)(shui)(shui)基(ji)組成的(de)化合(he)物(wu)。潤濕劑溶于水(shui)(shui)(shui)時，其(qi)分子*被水(shui)(shui)(shui)分子包圍(wei)，親(qin)水(shui)(shui)(shui)基(ji)一端(duan)被水(shui)(shui)(shui)分子吸引(yin)，疏(shu)水(shui)(shui)(shui)基(ji)一端(duan)則被排斥(chi)伸向(xiang)空中(zhong)，這樣(yang)潤濕劑物(wu)質(zhi)的(de)分子系在水(shui)(shui)(shui)溶液表面(mian)形成緊密的(de)定向(xiang)排列(lie)層(界面(mian)吸附(fu)層)，使水(shui)(shui)(shui)的(de)表面(mian)分子與(yu)空氣(qi)接觸狀態(tai)發生變化，接觸面(mian)積大大縮小(xiao)，導致水(shui)(shui)(shui)的(de)表面(mian)張力降低，同時朝向(xiang)空氣(qi)的(de)疏(shu)水(shui)(shui)(shui)基(ji)與(yu)粉塵之(zhi)間有吸附(fu)作(zuo)用，而把(ba)塵粒帶入水(shui)(shui)(shui)中(zhong)，使得粉塵得到充分潤濕。
