廠傢對燃氣熱風爐水處理的措施介紹

燃氣熱風爐的補給水和冷凝熱風爐有著很大的不同，燃氣加熱熱風爐補水量可以高達100%，遠遠高於冷凝熱風爐的供水量。燃氣熱風爐的補給水處理是要按照預處理，軟化，除鹽等步驟進行的。下面，熱風爐廠傢來介紹燃氣熱風爐補給水處理的有效措施。當燃氣熱風爐的軟化水為地表原水時,預處理的目的是去除水中的懸浮物,凝膠含量和有機質。在原水中添加硫酸鋁等,使雜質凝結成較大的顆粒,借體重和下沉,然後過濾掉。當地下水或城市水為補給水,原水預處理可以過濾。設備在脈沖式液壓機械攪拌澄清器的沖擊下，虹吸過濾過濾設備和無閥過濾器，單流或雙流式機械過濾器等一起去除水中的有機物質。
The supply water of gas heated hot blast stove is very different from that of condensing hot blast stove. The supply water of gas heated hot blast stove can be as high as 100%, which is much higher than that of condensing hot blast stove. The recharge water treatment of gas hot blast stove should be carried out according to the steps of pretreatment, softening and desalination. Next, the hot blast stove manufacturers to introduce the gas印花地坪 hot blast stove supply water treatment effective measures. 1。預處理
1. Preprocessing

The purpose of pretreatment is to remove suspended solids, gel content and organic matter in water. Adding aluminium sulfate to raw water can make the impurities coagulate into larger particles, borrow weight and sink, and then filter out. When groundwater or urban water is recharge water, raw water pretreatment can be filtered. Under the impact of impulse hydraulic mechanical stirring clarifier, siphon filter equipment and valveless filter, single-flow or double-flow mechanical filter together remove organic substances in water.
2。軟化
2. Soften
燃氣熱風爐使用天然或人工離子交換劑時,鈣和鎂鹽形成瞭硬垢。為瞭防止熱風爐管壁形成鈣鎂硬垢。碳酸氫鈣鎂的高堿性水,也可以使用氫鈉離子交換方法和預處理方法來處理工業熱風爐的的硬垢。這樣處理過的水也能達到軟化水的效果。
Calcium and magnesium salts form hard scales when natural or artificial ion exchangers are used in gas hot blast stoves. In order to prevent Ca-Mg hard scale from forming on the tube wall of hot blast stove. Calcium magnesium bicarbonate water with high alkalinity can also be treated by sodium hydrogen ion exchange method and pretreatment method. The treated water ca环氧地坪n also soften the water.
3。除鹽
3. Desalting
隨著燃氣熱風爐不斷的改進熱風爐參數和直流熱風爐的出現,熱風爐給水鹽度必須采用海水淡化的方法。化學海水淡化是一個廣泛使用的技術。最常用的方法是使用陽離子交換樹脂和陰離子交換樹脂,和陰陽樹脂樹脂這三種方法。在離子交換中,鹽水流經樹脂、陽離子和陰離子的鹽度轉換後除鹽瞭。這是比較簡單的化學除鹽方式。
With the continuous improvement of hot blast stove parameters and the appearance of direct current hot blast stove, the desalination method must be adopted in the feed water salinity of hot blast stove. Chemical seawater desalination is a widely used technology. The most commonly used methods are cation exchange resin and anion exchange resin, and anion and Yang resin. In ion exchange, saline water is desalted by changing the salinity of resin, cation and anion. This is a relatively simple chemical desalting method.
