style="margin-top:6.6000pt;margin-right:0.0000pt;margin-bottom:18.9000pt;margin-left:0.0000pt;padding:0pt 0pt 0pt 0pt;"> <span style="font-size:16px;">鍋爐軟化水設備主要包括補給水處理、凝結水處理、給水除氧、給水加氨和鍋內加藥處理四部分。那么，日常的鍋爐水處理可以分為幾部分。那么，鍋爐水處理中的補給步驟是什么</span><span style="font-size:16px;">？</span> </p> <p class="p" style="margin-top:6.6000pt;margin-right:0.0000pt;margin-bottom:18.9000pt;margin-left:0.0000pt;padding:0pt 0pt 0pt 0pt;"> <span style="font-size:16px;">鍋爐水處理因蒸汽用途和凝結水回收程度的不同，鍋爐的補給水量也不相同。凝汽式電站鍋爐的補給水量一般低于蒸發(fā)量的</span><span style="font-size:16px;">3%</span><span style="font-size:16px;">，供熱鍋爐的補給水量可高達</span><span style="font-size:16px;">100%</span><span style="font-size:16px;">。</span> </p> <p class="p" style="margin-top:6.6000pt;margin-right:0.0000pt;margin-bottom:18.9000pt;margin-left:0.0000pt;padding:0pt

<span style="font-size:16px;">1</span><span style="font-size:16px;">、預處理</span> </p> <p class="p" align="center" style="text-align:left;margin:6.6pt 0pt 18.9pt;padding:0pt;"> <span style="font-size:16px;"> </span><span style="font-size:16px;">當原水為地表水時(shí)，預處理的目的是除去水中的懸浮物、膠體物和有機物等。通常是在原水中投加混凝劑，使上述雜質(zhì)凝聚成大的顆粒，借自重而下沉，后過(guò)濾成清水。當以地下水或城市用水作補給水時(shí)，可直接過(guò)濾。常用的澄清設備有脈沖式、水力加速式和機械攪拌式澄清器</span><span style="font-size:16px;">;</span><span style="font-size:16px;">過(guò)濾設備有虹吸濾池、無(wú)閥濾池和單流式或雙流式機械過(guò)濾器等。為了進(jìn)一步清除水中的有機物，還可增設活性炭過(guò)濾器。</span> </p> <p class="p" style="margin-top:6.6000pt;margin-right:0.0000pt;margin-bottom:18.9000pt;margin-left:0.0000pt;padding:0pt 0pt 0pt 0pt;"> <span style="font-size:16px;">2</span><span style="font-size:16px;">、軟化</span><span style="font-size:16px;"> </span> </p> <p class="p" style="margin-top:6.6000pt;margin-right:0.0000pt;margin-bottom:18.9000pt;margin-left:0.0000pt;padding:0pt 0pt 0pt 0pt;"> <span style="font-size:16px;">采用天然或人造的離子交換劑</span><span style="font-size:16px;">,</span><span style="font-size:16px;">將鈣、鎂硬鹽轉變成不結硬垢的鹽，以防止鍋爐管子內壁結成鈣鎂硬水垢。對含鈣鎂重碳酸鹽且堿度較高的水，也可采用氫鈉離子交換法或在預處理中加以解決。</span> </p> <p class="p" style="margin-top:6.6000pt;margin-right:0.0000pt;margin-bottom:18.9000pt;margin-left:0.0000pt;padding:0pt 0pt 0pt 0pt;"> <span style="font-size:16px;">3</span><span style="font-size:16px;">、除鹽</span> </p> <p class="p" style="margin-top:6.6000pt;margin-right:0.0000pt;margin-bottom:18.9000pt;margin-left:0.0000pt;padding:0pt 0pt 0pt 0pt;"> <span style="font-size:16px;">化學(xué)除鹽所采用的離子交換劑品種很多，使用普遍的是陽(yáng)離子交換樹(shù)脂和陰離子交換樹(shù)脂，簡(jiǎn)稱(chēng)</span><span style="font-size:16px;">“</span><span style="font-size:16px;">陽(yáng)樹(shù)脂</span><span style="font-size:16px;">”</span><span style="font-size:16px;">和</span><span style="font-size:16px;">“</span><span style="font-size:16px;">陰樹(shù)脂</span><span style="font-size:16px;">”</span><span style="font-size:16px;">。在離子交換器中，含鹽水流經(jīng)樹(shù)脂時(shí)，鹽分中的陽(yáng)離子和陰離子分別與樹(shù)脂中的陽(yáng)離子</span><span style="font-size:16px;">(H+)</span><span style="font-size:16px;">和陰離子</span><span style="font-size:16px;">(OH-)</span><span style="font-size:16px;">發(fā)生變換后被除去。</span> </p> <p class="p"

style="font-size:16px;">當水的堿度較高時(shí)，在陽(yáng)離子交換器之后一般都要求串聯(lián)脫碳器以除去二氧化碳。含鹽量特別高的水，也可采用反滲透或電滲析工藝，先淡化水質(zhì)，再進(jìn)入離子交換器進(jìn)行深度除鹽。對高壓以上的鍋筒鍋爐或直流鍋爐，還必須除去給水中的微量硅</span><span style="font-size:16px;">;</span><span style="font-size:16px;">中、低壓鍋爐則按含量情況處理。</span> </p> <p class="p"
