如何解决脱硫塔塔堵问题？
脱硫塔堵塔会形成脱硫塔阻力上升，严重时发生气体带液，影响生产，是脱硫行业较普遍关注的问题。
Blockage of desulfurization tower will result in the increase of resistance of desulfurization tower, which will cause fluid entrainment and affect production. It is a common concern in desulfurization industry.
1、做好气体入塔前的净化，并加强气水分离，防止煤焦油、粉煤灰等杂物带入脱硫系统。
1. Purify the gas before entering the tower, and strengthen the separation of gas and water to prevent impurities such as coal tar and fly ash from entering the desulfurization system.
2、认真查找堵塔的根本原因，是设备设计安装问题的，找机会进行技术改造，比如脱硫塔在填料的装填和选用；气液分布器、再分布器、除沫器等部件设计应合理，气液分布面要适当等。
2. Find out the basic reason of blocking tower seriously is the problem of equipment design and installation, find the opportunity to carry out technical transformation, such as the filling and selection of desulfurization tower in the packing, the design of gas-liquid distributor, redistributor, demister and other components should be reasonable, and the gas-liquid distribution should be appropriate.
3、严格控制工艺指标，做好再生槽硫泡沫的浮选和溢流，再生压力及液位要稳定，控制好再生温度。
3, strictly control the process index, do well the floatation and overflow of the sulfur foam in the regeneration tank, stabilize the regeneration pressure and liquid level, and control the regeneration temperature.
4、保证足够的循环量和喷淋密度，使附在填料表面的积硫得到冲刷。重视熔硫回收及加工，熔硫残液要经逐级沉淀、过滤、冷却、氧化并将杂质清除后再返回到系统。
4. Ensure enough circulation and spraying density, so that the sulfur deposited on the surface of filler can be washed out. Attention should be paid to the recovery and processing of molten sulphur. The Residual Sulphur should be precipitated, filtered, cooled and oxidized step by step, and the impurities should be removed before returning to the system.
5、选用质量过硬的催化剂，如888催化剂能不断地释放出具有很强活性的原子态氧，能迅速将H2S和部分有机硫转化为单质硫，从而大大提高脱硫效率，同时氧化再生时能析出较大硫颗粒，易分离回收。还能形成多硫化物，再生时可析出硫，故具有一定的清洗塔的作用。
5. Selecting high-quality catalysts, such as 888 catalyst, can continuously release highly active atomic oxygen, which can rapidly convert H2S and part of organic sulfur into elemental sulfur, thus greatly www.dianLiwuzi.com.cnwww.btwujin.cnwww.bjsrxhsart.cnwww.huafuly.cnimproving desulfurization www.huizhuanyao5.com.cnwww.gzdebon.com.cnefficiency. At the same time, larger sulfur particles can be precipitated during oxidation regeneration, which is easy to separate and recover. It can also form polysulfides, and sulfur can be precipitated during regeneration, so it has a certain role in cleaning tower.
6、对塔堵后，阻力上升，出塔气体出现带液现象的处理：一方面可加大循环量来冲塔，另一方面可在贪液中加入一定量的植物油，以消除塔内沉积在填料上的硫泡及积硫。
6. After blocking the tower, the resistance rises and the gas from the tower is liquid-laden. On the one hand, the circulation can be increased to flush the tower, on the other hand, a certain amount of vegetable oil can be added to the greedy liquid to eliminate the sulfur bubbles and sulfur accumulation deposited on the packing in the tower.
