什么是通風設備_通風設備有哪些

　　機械通風是以風機為動力造成空氣流動。機械通風不受自然條件的限制，可以根據需要進行送風和排  通風設備(bei)獲得穩定的通(tong)風效果。在(zai)某(mou)(mou)些(xie)場(chang)合常(chang)兼用機(ji)(ji)械通(tong)風和自然通(tong)風。某(mou)(mou)些(xie)房(fang)(fang)間(jian)對空氣環(huan)境有(you)較高的要求(qiu),不(bu)允許周(zhou)圍(wei)空氣流(liu)(liu)入（如醫院的手術室(shi)、實驗大(da)(da)(da)(da)樓中(zhong)的精密儀(yi)器室(shi)等(deng)），這(zhe)些(xie)房(fang)(fang)間(jian)的機(ji)(ji)械送風量(liang)應大(da)(da)(da)(da)于機(ji)(ji)械排風量(liang)(或者(zhe)只設(she)機(ji)(ji)械送風,全部用自然排風),使(shi)室(shi)內(nei)壓(ya)力(li)大(da)(da)(da)(da)于大(da)(da)(da)(da)氣壓(ya)力(li)。室(shi)內(nei)多余(yu)的空氣會通(tong)過(guo)門、窗(chuang)和其他縫隙流(liu)(liu)至室(shi)外(wai)。某(mou)(mou)些(xie)污染(ran)較嚴重的房(fang)(fang)間(jian)（如廁所、廚房(fang)(fang)等(deng)），為了防止其中(zhong)的污濁(zhuo)空氣流(liu)(liu)入周(zhou)圍(wei)的空間(jian)，應使(shi)室(shi)內(nei)的壓(ya)力(li)小于大(da)(da)(da)(da)氣壓(ya)力(li)，使(shi)室(shi)內(nei)的污濁(zhuo)空氣不(bu)致流(liu)(liu)至室(shi)外(wai)。

      通風設備的用途 

通(tong)風系統(tong)中常用(yong)(yong)(yong)的(de)(de)有害(hai)氣(qi)(qi)體(ti)處理方法有吸(xi)(xi)收(shou)(shou)法和吸(xi)(xi)附(fu)法。吸(xi)(xi)收(shou)(shou)法是利用(yong)(yong)(yong)適當的(de)(de)液體(ti)作(zuo)為吸(xi)(xi)收(shou)(shou)劑(ji)(ji)與(yu)含有害(hai)氣(qi)(qi)體(ti)的(de)(de)空氣(qi)(qi)相接(jie)觸，使有害(hai)氣(qi)(qi)體(ti)被吸(xi)(xi)收(shou)(shou)劑(ji)(ji)所吸(xi)(xi)收(shou)(shou)或者與(yu)吸(xi)(xi)收(shou)(shou)劑(ji)(ji)發(fa)生化學反應(ying)而(er)變為無(wu)害(hai)物(wu)質(zhi)。吸(xi)(xi)附(fu)法是利用(yong)(yong)(yong)某些(xie)具(ju)有較大吸(xi)(xi)附(fu)能力的(de)(de)物(wu)質(zhi)作(zuo)為吸(xi)(xi)附(fu)劑(ji)(ji)，吸(xi)(xi)附(fu)有害(hai)氣(qi)(qi)體(ti)。活性炭是工業上應(ying)用(yong)(yong)(yong)最廣(guang)泛(fan)的(de)(de)一種(zhong)吸(xi)(xi)附(fu)劑(ji)(ji)。吸(xi)(xi)附(fu)法適用(yong)(yong)(yong)于處理危(wei)害(hai)大的(de)(de)低濃(nong)度有害(hai)氣(qi)(qi)體(ti),吸(xi)(xi)附(fu)效(xiao)率可接(jie)近100%。某些(xie)有害(hai)氣(qi)(qi)體(ti)由于目(mu)前(qian)還缺乏經濟(ji)、有效(xiao)的(de)(de)處理方法,在不(bu)得已(yi)的(de)(de)情況下可以用(yong)(yong)(yong)高(gao)煙囪把(ba)未(wei)經處理或處理不(bu)完全的(de)(de)空氣(qi)(qi)排入高(gao)空。這種(zhong)方法稱為高(gao)空排放。 

           通風設備的價格

由于通(tong)風(feng)(feng)設備的(de)(de)(de)特殊性，其原材(cai)料(liao)、工藝(yi)、批量數、通(tong)風(feng)(feng)按照(zhao)范圍可分為(wei)全面(mian)通(tong)風(feng)(feng)和局部通(tong)風(feng)(feng)等綜合因(yin)素(su)的(de)(de)(de)影響，導(dao)致它的(de)(de)(de)價(jia)(jia)格差(cha)異也很大(da)。一(yi)般玻(bo)璃(li)鋼的(de)(de)(de)價(jia)(jia)格為(wei)幾百元一(yi)平(ping)米，或是上千元一(yi)平(ping)米，制作工藝(yi)精密的(de)(de)(de)潔凈通(tong)風(feng)(feng)設備的(de)(de)(de)價(jia)(jia)格還(huan)可能(neng)更貴。
