鍋爐煙(yan)(yan)氣煙(yan)(yan)塵監測是一(yi)項全面而復雜的(de)(de)工(gong)作(zuo)，不僅(jin)要求監測人(ren)員熟練(lian)掌握專業(ye)知識和操作(zuo)技(ji)能，還需(xu)具備豐(feng)富的(de)(de)現場經驗。本(ben)文將(jiang)對鍋爐煙(yan)(yan)氣煙(yan)(yan)塵監測的(de)(de)流(liu)程進行簡要介紹。

　　監測儀器設備的準備和檢查

　　1濾筒的準備

　　濾筒是一種捕集率高、阻力小、便于放入煙道內采樣的捕塵裝置。我們常用的是玻璃纖維濾筒，玻璃纖維濾筒由超細玻璃纖維制成，對于0.5um以上的塵粒的捕集效率達99.9%以上。適用于500℃以下的煙氣采集。

　　濾(lv)(lv)(lv)(lv)筒(tong)準(zhun)備(bei)時(shi)(shi)(shi)需(xu)要進行認(ren)真的篩(shai)選，濾(lv)(lv)(lv)(lv)筒(tong)太(tai)薄(bo)、太(tai)厚及厚薄(bo)不(bu)(bu)均勻(yun)的要剔除，這是因為筒(tong)壁(bi)致密(mi)不(bu)(bu)均勻(yun)、筒(tong)壁(bi)表面稀疏的濾(lv)(lv)(lv)(lv)筒(tong)在(zai)測量和稱重時(shi)(shi)(shi)容易部分掉落；筒(tong)壁(bi)太(tai)薄(bo)，強度太(tai)低，監測過(guo)程(cheng)中(zhong)容易破裂；筒(tong)壁(bi)太(tai)厚，采樣阻(zu)力(li)較大，影響塵粒吸入。監測過(guo)程(cheng)中(zhong)，還必須(xu)有空白濾(lv)(lv)(lv)(lv)筒(tong)的全程(cheng)伴隨，作為該批濾(lv)(lv)(lv)(lv)筒(tong)的誤差校正。應將檢驗合格的濾(lv)(lv)(lv)(lv)筒(tong)用(yong)(yong)(yong)鉛(qian)筆(bi)編號，在(zai)105—110的烘箱(xiang)內烘烤(kao)1小時(shi)(shi)(shi)，取出(chu)置于(yu)干燥(zao)箱(xiang)內，冷(leng)(leng)卻(que)至室(shi)溫，用(yong)(yong)(yong)萬分之一天平恒重。當(dang)濾(lv)(lv)(lv)(lv)筒(tong)在(zai)400℃以上(shang)高(gao)溫排氣(qi)中(zhong)使用(yong)(yong)(yong)時(shi)(shi)(shi)，為減(jian)少濾(lv)(lv)(lv)(lv)筒(tong)本身減(jian)重帶來的誤差，應預先在(zai)400℃高(gao)溫箱(xiang)中(zhong)烘烤(kao)1小時(shi)(shi)(shi)，然后(hou)放(fang)入干燥(zao)箱(xiang)中(zhong)，冷(leng)(leng)卻(que)至室(shi)溫，稱量至恒重。

　　2現場監測前對煙氣測試儀器進行全面檢查

　　首先(xian)確認(ren)電(dian)源(yuan)電(dian)壓是(shi)(shi)否符合儀器(qi)使(shi)用要求，檢查(cha)顯(xian)示器(qi)、鍵(jian)盤、采(cai)樣泵(beng)等各項(xiang)功能是(shi)(shi)否正(zheng)(zheng)常(chang)，干燥筒中加入約(yue)為3/4體積的具(ju)有(you)充分(fen)干燥能力的變色硅膠（顆粒狀），使(shi)用標準氣(qi)(qi)(qi)體校準氣(qi)(qi)(qi)體組分(fen)（O2、SO2、NOX）傳感器(qi)，尤其要注(zhu)意SO2的反應滯后時間長。檢查(cha)儀器(qi)管路系統(tong)連接(jie)和氣(qi)(qi)(qi)密(mi)(mi)性是(shi)(shi)否完好(hao)，檢查(cha)膠管是(shi)(shi)否存在(zai)折點或堵塞，氣(qi)(qi)(qi)密(mi)(mi)性檢查(cha)方法(fa)：連接(jie)好(hao)儀器(qi)，選用等速流量采(cai)樣，用手(shou)指壓住進氣(qi)(qi)(qi)端口(kou)，如泵(beng)的聲音突(tu)然加大，松手(shou)后恢復正(zheng)(zheng)常(chang)，則(ze)氣(qi)(qi)(qi)密(mi)(mi)性正(zheng)(zheng)常(chang)。

　　監測位置與采樣點的選擇

　　為取得(de)具有代表(biao)性樣(yang)品，采(cai)樣(yang)位(wei)(wei)置應(ying)優先選擇在煙囪或地面(mian)管道(dao)氣流平穩的垂直管段中，避開煙道(dao)彎頭(tou)和(he)(he)斷(duan)面(mian)形(xing)狀急劇變(bian)化的部位(wei)(wei)。采(cai)樣(yang)位(wei)(wei)置應(ying)距煙道(dao)的彎頭(tou)、接頭(tou)、閥門和(he)(he)其(qi)他變(bian)徑(jing)(jing)管的下(xia)游方向(xiang)(xiang)大(da)于6倍直徑(jing)(jing)和(he)(he)距上(shang)述部位(wei)(wei)的上(shang)游方向(xiang)(xiang)大(da)于3倍直徑(jing)(jing)處。對矩形(xing)煙道(dao)，其(qi)當(dang)(dang)量直徑(jing)(jing)D=2AB/(A+B)，式中A、B為邊長(chang)。當(dang)(dang)測(ce)試(shi)現場(chang)空間位(wei)(wei)置有限(xian)，很(hen)難滿(man)足上(shang)述要求時(shi)，采(cai)樣(yang)斷(duan)面(mian)與彎頭(tou)等的距離至少(shao)是煙道(dao)直徑(jing)(jing)的1.5倍處，并應(ying)適當(dang)(dang)增加測(ce)點(dian)的數量。采(cai)樣(yang)斷(duan)面(mian)的氣流最好(hao)在5m/s以(yi)上(shang)。

　　采(cai)樣(yang)點(dian)(dian)數(shu)(shu)量(liang)的(de)多(duo)少(shao)主要與煙(yan)(yan)(yan)(yan)道(dao)采(cai)樣(yang)斷(duan)(duan)(duan)面(mian)(mian)截面(mian)(mian)積的(de)形狀、大(da)小、斷(duan)(duan)(duan)面(mian)(mian)煙(yan)(yan)(yan)(yan)氣(qi)流動的(de)分(fen)布(bu)狀態是(shi)否均(jun)勻有關。必須按照一定(ding)(ding)的(de)原則在同一斷(duan)(duan)(duan)面(mian)(mian)內進行多(duo)點(dian)(dian)測(ce)(ce)量(liang)，才能取得較為準確(que)的(de)數(shu)(shu)據。對于圓(yuan)形煙(yan)(yan)(yan)(yan)道(dao)斷(duan)(duan)(duan)面(mian)(mian)分(fen)成一定(ding)(ding)數(shu)(shu)量(liang)的(de)同心等面(mian)(mian)積圓(yuan)環來確(que)定(ding)(ding)采(cai)樣(yang)點(dian)(dian)的(de)位置和數(shu)(shu)量(liang)；而(er)方(fang)形或矩(ju)形煙(yan)(yan)(yan)(yan)道(dao)，則將煙(yan)(yan)(yan)(yan)道(dao)斷(duan)(duan)(duan)面(mian)(mian)分(fen)成適量(liang)的(de)等面(mian)(mian)積小塊，各塊中心即為測(ce)(ce)點(dian)(dian)。當(dang)采(cai)樣(yang)斷(duan)(duan)(duan)面(mian)(mian)遠離彎頭、閥(fa)門和變徑管(guan)時(shi)，斷(duan)(duan)(duan)面(mian)(mian)測(ce)(ce)出的(de)煙(yan)(yan)(yan)(yan)氣(qi)流速和塵粒分(fen)布(bu)是(shi)比較均(jun)勻的(de)，這時(shi)可適當(dang)較少(shao)測(ce)(ce)點(dian)(dian)數(shu)(shu)量(liang)；但有時(shi)由于采(cai)樣(yang)現(xian)場的(de)限(xian)制，找不到(dao)理(li)想的(de)斷(duan)(duan)(duan)面(mian)(mian)，不得不在距離彎頭、變徑管(guan)較近的(de)位置選擇斷(duan)(duan)(duan)面(mian)(mian)，此斷(duan)(duan)(duan)面(mian)(mian)處(chu)的(de)煙(yan)(yan)(yan)(yan)氣(qi)流動狀態通(tong)常是(shi)不均(jun)勻的(de)，甚(shen)至比較紊(wen)亂，這種情況應(ying)當(dang)增加采(cai)樣(yang)點(dian)(dian)數(shu)(shu)量(liang)。

　　鍋爐工(gong)況的確定

　　鍋(guo)(guo)爐(lu)運(yun)行負荷(he)是(shi)影響煙(yan)(yan)塵排放濃(nong)(nong)度的(de)(de)重要因素，必須保證(zheng)鍋(guo)(guo)爐(lu)設備(bei)的(de)(de)正常(chang)運(yun)轉和工(gong)況負荷(he)的(de)(de)穩定(ding)性。現場(chang)監(jian)測時應(ying)有(you)人專門監(jian)督被測鍋(guo)(guo)爐(lu)的(de)(de)工(gong)況，保證(zheng)鍋(guo)(guo)爐(lu)及其除塵設施正常(chang)運(yun)行，滿足監(jian)測條件。鍋(guo)(guo)爐(lu)煙(yan)(yan)塵測試(shi)方法》GB5468-1991中規定(ding)，在(zai)(zai)用鍋(guo)(guo)爐(lu)煙(yan)(yan)塵排放濃(nong)(nong)度的(de)(de)測試(shi)，必須在(zai)(zai)鍋(guo)(guo)爐(lu)設計出力70%以(yi)上(shang)的(de)(de)情況下進行。

　　測定煙氣壓力、流速、選擇采樣嘴

　　在(zai)煙(yan)道(dao)(dao)中(zhong)流動(dong)(dong)的(de)氣體同時受到(dao)動(dong)(dong)壓(ya)和(he)靜壓(ya)作用，如果不(bu)能(neng)正確(que)地測(ce)得這兩種壓(ya)力(li)，將對采(cai)(cai)(cai)(cai)(cai)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)嘴(zui)的(de)選(xuan)擇(ze)(ze)及(ji)等(deng)速(su)(su)采(cai)(cai)(cai)(cai)(cai)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)流量(liang)的(de)計算(suan)結(jie)果產生誤差，測(ce)量(liang)動(dong)(dong)壓(ya)、靜壓(ya)時若儀(yi)器顯示動(dong)(dong)壓(ya)很低(di)或為零，則應互換動(dong)(dong)壓(ya)管和(he)靜壓(ya)管，測(ce)定(ding)時皮(pi)托管嘴(zui)動(dong)(dong)壓(ya)向(xiang)要(yao)對準氣流方(fang)向(xiang)。為了從煙(yan)道(dao)(dao)得到(dao)有代表性的(de)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)品，須等(deng)速(su)(su)采(cai)(cai)(cai)(cai)(cai)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)，即氣體進入采(cai)(cai)(cai)(cai)(cai)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)嘴(zui)的(de)速(su)(su)度和(he)采(cai)(cai)(cai)(cai)(cai)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)點(dian)(dian)的(de)煙(yan)氣流速(su)(su)相(xiang)等(deng)。采(cai)(cai)(cai)(cai)(cai)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)速(su)(su)度大于或小于采(cai)(cai)(cai)(cai)(cai)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)點(dian)(dian)的(de)氣流速(su)(su)度都將使采(cai)(cai)(cai)(cai)(cai)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)結(jie)果產生偏(pian)差。維(wei)持等(deng)速(su)(su)采(cai)(cai)(cai)(cai)(cai)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)的(de)方(fang)法是測(ce)定(ding)煙(yan)氣流速(su)(su)的(de)同時進行等(deng)速(su)(su)跟蹤采(cai)(cai)(cai)(cai)(cai)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)。在(zai)事先根據煙(yan)道(dao)(dao)的(de)形狀，煙(yan)道(dao)(dao)的(de)尺寸（壁(bi)厚，內控尺寸，采(cai)(cai)(cai)(cai)(cai)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)孔長）測(ce)量(liang)確(que)定(ding)的(de)采(cai)(cai)(cai)(cai)(cai)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)點(dian)(dian)上依次(ci)測(ce)量(liang)各(ge)點(dian)(dian)的(de)流速(su)(su)，測(ce)量(liang)完畢(bi)后根據各(ge)點(dian)(dian)的(de)平均流速(su)(su)由煙(yan)塵(chen)采(cai)(cai)(cai)(cai)(cai)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)器自動(dong)(dong)計算(suan)選(xuan)擇(ze)(ze)合適的(de)采(cai)(cai)(cai)(cai)(cai)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)嘴(zui)。也可以(yi)手動(dong)(dong)選(xuan)擇(ze)(ze)采(cai)(cai)(cai)(cai)(cai)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)嘴(zui)，但采(cai)(cai)(cai)(cai)(cai)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)嘴(zui)的(de)大小選(xuan)擇(ze)(ze)原則是“高(gao)流速(su)(su)小采(cai)(cai)(cai)(cai)(cai)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)嘴(zui)，低(di)流速(su)(su)大采(cai)(cai)(cai)(cai)(cai)樣(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)(yang)嘴(zui)”。

　　濕(shi)度的測量(liang)

　　煙(yan)氣(qi)(qi)的(de)(de)濕(shi)度(du)(du)(du)(du)測(ce)量(liang)有重量(liang)法(fa)、冷凝法(fa)和干(gan)濕(shi)球(qiu)法(fa)等方法(fa)。現(xian)在(zai)我們使用的(de)(de)煙(yan)塵采(cai)樣(yang)器多采(cai)用干(gan)濕(shi)球(qiu)法(fa)，此方法(fa)使氣(qi)(qi)體(ti)在(zai)一定的(de)(de)速度(du)(du)(du)(du)下流經(jing)干(gan)、濕(shi)球(qiu)溫度(du)(du)(du)(du)計。根(gen)據干(gan)濕(shi)球(qiu)溫度(du)(du)(du)(du)計和測(ce)點處的(de)(de)排氣(qi)(qi)壓力，計算(suan)出排氣(qi)(qi)的(de)(de)水分含(han)量(liang)，當干(gan)濕(shi)球(qiu)溫度(du)(du)(du)(du)計穩定后，記錄干(gan)濕(shi)球(qiu)的(de)(de)溫度(du)(du)(du)(du)。當被測(ce)氣(qi)(qi)體(ti)溫度(du)(du)(du)(du)較高時，導致(zhi)濕(shi)球(qiu)溫度(du)(du)(du)(du)升(sheng)至100℃，這時濕(shi)球(qiu)溫度(du)(du)(du)(du)不(bu)再受氣(qi)(qi)體(ti)濕(shi)度(du)(du)(du)(du)的(de)(de)影響，因此不(bu)能(neng)再用干(gan)濕(shi)球(qiu)法(fa)測(ce)量(liang)這種狀態(tai)下的(de)(de)氣(qi)(qi)體(ti)濕(shi)度(du)(du)(du)(du)。

　　采樣

　　煙(yan)氣采樣中(zhong)，出現(xian)含氧(yang)量(liang)(liang)偏高(gao)甚(shen)至很高(gao)的(de)(de)現(xian)象，是由于鍋爐系統(tong)(tong)(tong)的(de)(de)除塵凈化器和鍋爐尾部的(de)(de)煙(yan)道密封不嚴造(zao)成(cheng)的(de)(de)，或者是鍋爐系統(tong)(tong)(tong)的(de)(de)引風(feng)量(liang)(liang)大而輸煤量(liang)(liang)小，不匹配造(zao)成(cheng)的(de)(de)。應當對鍋爐系統(tong)(tong)(tong)進行堵(du)漏維(wei)修，調整鍋爐運行狀況，使鍋爐系統(tong)(tong)(tong)運行正常。

　　數據的記錄和處理

　　配備專門的記錄本，詳細記錄鍋(guo)爐的型(xing)號(hao)、生(sheng)產(chan)廠(chang)家、除塵設備型(xing)號(hao)、生(sheng)產(chan)廠(chang)家、煙囪的高度、直徑(jing)、環(huan)境溫度、大氣壓、風(feng)向(xiang)、風(feng)速等。檢查核實(shi)每個數據(ju)和(he)計算結(jie)果，保(bao)證(zheng)準(zhun)確無誤。根據(ju)監(jian)測數據(ju)和(he)計算結(jie)果填(tian)好監(jian)測表格。

　　鍋爐煙氣煙塵監測是環保部門最基本的監測內容，但由(you)于(yu)鍋爐種(zhong)類眾多，實際現場情(qing)況復雜，我(wo)們應依據《鍋爐煙塵監測方法》的標準，針(zhen)對各種(zhong)情(qing)況分重點(dian)選(xuan)擇性對待，保證監測結果(guo)的正確性、科學性、準確性。
