如何對螺(luo)旋風(feng)(feng)管(guan)的通風(feng)(feng)管(guan)進行消毒?

　　在(zai)(zai)(zai)(zai)新型冠狀病毒(du)肆虐的(de)(de)情況(kuang)下(xia)，人們擔心氣(qi)溶(rong)膠(jiao)(jiao)(jiao)(jiao)的(de)(de)傳播(bo)。那(nei)么(me)，什(shen)么(me)是(shi)氣(qi)溶(rong)膠(jiao)(jiao)(jiao)(jiao)傳播(bo)呢?氣(qi)溶(rong)膠(jiao)(jiao)(jiao)(jiao)傳播(bo)一般意味著飛沫混合(he)氣(qi)體漂浮(fu)在(zai)(zai)(zai)(zai)空氣(qi)中，形(xing)成氣(qi)溶(rong)膠(jiao)(jiao)(jiao)(jiao)。這種(zhong)氣(qi)溶(rong)膠(jiao)(jiao)(jiao)(jiao)含有一定(ding)濃度的(de)(de)病毒(du)，氣(qi)溶(rong)膠(jiao)(jiao)(jiao)(jiao)不(bu)能(neng)長時間漂浮(fu)在(zai)(zai)(zai)(zai)空氣(qi)中。在(zai)(zai)(zai)(zai)重力(li)的(de)(de)作用(yong)下(xia)，它會落在(zai)(zai)(zai)(zai)一些物(wu)體上。

　　保(bao)護新型(xing)肺炎病(bing)(bing)(bing)毒(du)，要做到：勤洗手，多(duo)(duo)通(tong)(tong)(tong)風(feng)(feng)，少聚(ju)會(hui)，保(bao)持(chi)人(ren)與(yu)人(ren)之(zhi)間的距離，戴口罩。這(zhe)(zhe)么(me)(me)多(duo)(duo)通(tong)(tong)(tong)風(feng)(feng)的原(yuan)理是(shi)什么(me)(me)?如(ru)果在封閉(bi)的空(kong)間里，除(chu)了重力，氣(qi)溶(rong)膠(jiao)(jiao)(jiao)還會(hui)落在物體上，那(nei)(nei)么(me)(me)打開門窗通(tong)(tong)(tong)風(feng)(feng)豈不(bu)是(shi)對氣(qi)溶(rong)膠(jiao)(jiao)(jiao)施加外力，讓氣(qi)溶(rong)膠(jiao)(jiao)(jiao)在空(kong)中漂浮的時間更長(chang)?事(shi)實(shi)上，這(zhe)(zhe)種觀點(dian)也不(bu)能完全錯誤，只是(shi)考(kao)慮的范圍有點(dian)狹窄。真實(shi)情況(kuang)下(xia)，多(duo)(duo)通(tong)(tong)(tong)風(feng)(feng)會(hui)帶來(lai)更多(duo)(duo)的空(kong)氣(qi)，稀釋(shi)空(kong)間內的氣(qi)溶(rong)膠(jiao)(jiao)(jiao)。如(ru)果在低(di)(di)濃度下(xia)被(bei)人(ren)體吸入(ru)，就(jiu)會(hui)被(bei)人(ren)體的免疫(yi)系統清除(chu)，不(bu)構成生(sheng)病(bing)(bing)(bing)的風(feng)(feng)險。在多(duo)(duo)通(tong)(tong)(tong)風(feng)(feng)空(kong)間中，氣(qi)溶(rong)膠(jiao)(jiao)(jiao)的發病(bing)(bing)(bing)率遠低(di)(di)于(yu)封閉(bi)空(kong)間。所以(yi)，大(da)(da)樓、大(da)(da)地方的窗戶沒那(nei)(nei)么(me)(me)多(duo)(duo)怎么(me)(me)辦(ban)?這(zhe)(zhe)類大(da)(da)型(xing)建筑(zhu)都會(hui)安裝通(tong)(tong)(tong)風(feng)(feng)管道，通(tong)(tong)(tong)風(feng)(feng)管道中存在氣(qi)溶(rong)膠(jiao)(jiao)(jiao)的可能性很大(da)(da)，那(nei)(nei)么(me)(me)這(zhe)(zhe)類通(tong)(tong)(tong)風(feng)(feng)管道應(ying)該怎樣(yang)消毒(du)呢?如(ru)果像自來(lai)水池一(yi)樣(yang)使用(yong)氯氣(qi)消毒(du)管是(shi)不(bu)現(xian)實(shi)的，氯氣(qi)劇毒(du)氣(qi)體是(shi)首要選(xuan)擇，那(nei)(nei)么(me)(me)進氣(qi)口噴灑(sa)含(han)有消毒(du)水的，螺旋風(feng)(feng)道內壁的病(bing)(bing)(bing)毒(du)消毒(du)，進一(yi)步降低(di)(di)大(da)(da)型(xing)建筑(zhu)感染病(bing)(bing)(bing)毒(du)的風(feng)(feng)險。
