汽水取樣冷卻器用于鍋爐房或發(fā)電廠內(nèi)汽水化驗取樣冷卻，鍋爐及熱力系統(tǒng)中的水大都溫度較高,而高水溫不便于取樣,也不便于測定,在取樣中應(yīng)加以冷卻,所以要把取樣點的樣品引進取樣冷卻器進行冷卻,取樣冷卻器一般要求保證流量500-700mL/min時,樣品能冷取到30-40度以下,滿足中華人民國家電力行業(yè)DL/T 457—91的標準. </p> <p>

style="text-indent:25px">推入式煤粉取樣裝置工作原理1、推入式煤粉取樣裝置是利用負壓抽吸和旋風分離原理將氣粉混合物從煤粉管道中抽吸出并進行固氣分離而研制成功的。取樣前所有閥門全為關(guān)閉狀態(tài)，取樣時打開球閥13；調(diào)整壓縮空氣調(diào)壓閥，將壓力調(diào)整到合適的壓力時，打開球閥；搖動手輪1；傳動管（4）內(nèi)螺桿旋轉(zhuǎn)帶動取樣管7緩緩進入煤粉管道中開始取樣，取樣時所有閥門為開啟狀態(tài)，當壓縮空氣從出氣管道經(jīng)過射器抽氣器，其射流作用必然導致旋風分離器、取樣管、取樣瓶等部件產(chǎn)生負壓，促使煤粉管道中的氣粉混合物沿取樣管進入取樣裝置，氣粉混合物在旋風分離器中進行固氣分離，分離出的煤粉落入旋風分離器下面的取樣瓶中，整個操作過程對工作場所不產(chǎn)生污染。取樣前對壓縮空氣調(diào)壓閥進行調(diào)整，可實現(xiàn)等速取樣，使取出的煤粉樣品具有樣例性。（壓縮空氣壓力一般不超過0.1Mpa）。2、防堵措施設(shè)備使用過程中可以用壓縮空氣對取樣管進行吹掃，防止取樣管被煤粉堵塞。3、防磨措施不取樣時，取樣管退出煤粉管道避開煤粉氣流對取樣管的磨損。取樣時搖動手輪螺桿開始旋轉(zhuǎn)，將取樣管緩緩推入煤粉管道中開始取樣，取樣口對著煤粉氣流來向。取樣完畢，搖動手輪將取樣管緩緩退出煤粉管道，達到防磨目的。普遍用于：給水、爐水、蒸汽、凝結(jié)水、疏水、回水、冷凝水等等樣品取樣。</p><div

取樣過程中，當煙氣流進入取樣嘴后，經(jīng)過取樣管，沿器壁切線方向進入分離器，再沿器壁至上而下旋轉(zhuǎn)，在旋轉(zhuǎn)過程中，飛灰因重力慣性作用，被甩到器壁上，并沿器壁靠重力作用進入取樣瓶，而氣體由引出管排出。 </p> <p> 當煙氣流速為6m/s--14m/s
