    厂家对燃气热风炉水处理的措施介绍

    2018-12-12 08:50:36 无锡盛发地坪科技有限公司 阅读

    燃气热风炉的补给水和冷凝热风炉有着很大的不同,燃气加热热风炉补水量可以高达100%,远远高于冷凝热风炉的供水量。燃气热风炉的补给水处理是要按照预处理,软化,除盐等步骤进行的。下面,热风炉厂家来介绍燃气热风炉补给水处理的有效措施。当燃气热风炉的软化水为地表原水时,预处理的目的是去除水中的悬浮物,凝胶含量和有机质。在原水中添加硫酸铝等,使杂质凝结成较大的颗粒,借体重和下沉,然后过滤掉。当地下水或城市水为补给水,原水预处理可以过滤。设备在脉冲式液压机械搅拌澄清器的冲击下,虹吸过滤过滤设备和无阀过滤器,单流或双流式机械过滤器等一起去除水中的有机物质。

    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 hot blast stove supply water treatment effective measures. 1。预处理

    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。软化

    2. Soften

    燃气热风炉使用天然或人工离子交换剂时,钙和镁盐形成了硬垢。为了防止热风炉管壁形成钙镁硬垢。碳酸氢钙镁的高碱性水,也可以使用氢钠离子交换方法和预处理方法来处理工业热风炉的的硬垢。这样处理过的水也能达到软化水的效果。

    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 can also soften the water.

    3。除盐

    3. Desalting

    随着燃气热风炉不断的改进热风炉参数和直流热风炉的出现,热风炉给水盐度必须采用海水淡化的方法。化学海水淡化是一个广泛使用的技术。最常用的方法是使用阳离子交换树脂和阴离子交换树脂,和阴阳树脂树脂这三种方法。在离子交换中,盐水流经树脂、阳离子和阴离子的盐度转换后除盐了。这是比较简单的化学除盐方式。

    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.
