4、 Proper desulfurizer is not selected.

五、脫硫液效果不好，而貧液中硫含量高。回收的煙氣處理不好，煙氣中硫酸氫化鈉Na2CO3吸收了硫化氫，而不是總氧化元素硫，并收集了浮選泡沫塑料，在煙氣處理塔上完成氧化反應(yīng)，產(chǎn)生單質(zhì)硫，然后附著于包裝表面，這就形成了一段墻壁。

5、 The effect of desulfurization solution is poor, while the sulfur content in lean solution is high. The recovered flue gas is not well treated. The sodium hydride sulfate Na2CO3 in the flue gas absorbs hydrogen sulfide, not the total oxidized elemental sulfur, and collects the flotation foam. The oxidation reaction is completed on the flue gas treatment tower to produce elemental sulfur, which is then attached to the packaging surface, forming a section of wall.

六、硫磺的回收質(zhì)量：硫磺的回收質(zhì)量直接反映了硫磺的脫硫量。即便脫硫系統(tǒng)運(yùn)行正常，硫磺不出，也會(huì)卡在塔內(nèi)，給堵塔帶來隱患。將熔融硫回流到體系中是導(dǎo)致次生鹽含量過高的重要原因。

6、 Sulfur recovery quality: the sulfur recovery quality directly reflects the sulfur desulfurization amount. Even if the desulfurization system operates normally and the sulfur does not come out, it will still be stuck in the tower, bringing hidden dangers to tower plugging. The reflux of molten sulfur into the system is an important reason for the high content of secondary salts.

七、前段除塵效果：眾所周知，進(jìn)入脫硫系統(tǒng)的氣體成分復(fù)雜，含有大量雜質(zhì)和污物。低溫廢水回收設(shè)備一旦進(jìn)入，就很難取出。

7、 Dedusting effect of the front section: as we all know, the gas entering the desulfurization system has complex composition, containing a lot of impurities and dirt. Once the low-temperature wastewater recovery equipment enters, it is difficult to take it out.

我們在這里知道了低溫廢水回收設(shè)備造成堵塞的原因，就要從實(shí)際出發(fā)制定好相應(yīng)的方案才行，更多注意事項(xiàng)就來我們網(wǎng)站m.slzjx.cn咨詢?。?/div>
