硫会对环境造成严重污染，在环境保护工作中，治理硫氧化物和硫化氢对大气的污染，硫酸盐、硫化氢对水体的污染，一直是人们关注的课题。 但就像电力行业的热电厂一样，在消耗过程中需要熄灭大量的燃煤，如果燃煤中含有硫元素，熄灭后必然会释放出大量的SO2，如果不停止治理，将对环境造成巨大危害，因此电力行业普遍使用生物脱硫设备，那么，下面一起了解下生物脱硫设备的应用及自身防腐吧!
Sulfur will cause serious pollution to the environment. In the environmental protection work, it has always been a topic of concern to control the pollution of sulfur oxides and hydrogen sulfide to the atmosphere, and the pollution of sulfate and hydrogen sulfide to water bodies. But like the thermal power plants in the power industry, a large amount of coal needs to be extinguished in the process of consumption. If the coal contains sulfur, a large amount of SO2 will be released after being extinguished. If the treatment is not stopped, it will cause great harm to the environment. Therefore, biological desulfurization equipment is widely used in the power industry. Now let's learn about the application of biological desulfurization equipment and its own anti-corrosion!
生物脱硫设备
Biological desulfurization equipment
说到脱硫，目前业界的脱硫方法主要有三种。 分别是熄灯前脱硫、熄灯中脱硫和熄灯后脱硫。 其中一般使用石灰石停止使用脱硫的方法，所以今天的就集中在其中使用的生物脱硫设备吧。
Speaking of desulfurization, there are three main desulfurization methods in the industry. Desulfurization before light off, during light off and after light off. Among them, limestone is generally used to stop desulfurization, so today's Hengneng focuses on the biological desulfurization equipment.
生物脱硫设备的原理是将石灰石加水成浆，它能阻止烟气中的二氧化硫和氧化反响，生成硫酸钙。 经过不断的反响，硫酸钙达到一定的饱和度后，就构成了结晶二水石膏。 然后停止这些石膏的脱水处理，堆放在石膏储藏室。 生物脱硫后的烟气经过除雾器和换热器后，可通过烟囱排入大气，经脱硫设备处理的烟气脱硫效率可达95%。
The principle of biological desulfurization equipment is to add water to limestone to form slurry, which can prevent sulfur dioxide and oxidation reaction in flue gas and generate calcium sulfate. After constant response, calcium sulfate reaches a certain degree of saturation, which forms crystalline dihydrate gypsum. Then stop the dehydration of these gypsum and stack them in the gypsum storage room. The flue gas after biological desulfurization can be discharged into the atmosphere through the chimney after passing through the demister and heat exchanger, and the desulfurization efficiency of flue gas treated by the desulfurization equipment can reach 95%.
这种脱硫方法如此方便，除了自身的脱硫原理外，还需要高质量的脱硫设备，为了更好地发挥脱硫效果，生物脱硫设备需要一定的耐腐蚀性，理由如下：
This desulfurization method is so convenient. In addition to its own desulfurization principle, it also requires high-quality desulfurization equipment. In order to give better play to the desulfurization effect, biological desulfurization equipment needs certain corrosion resistance. The reasons are as follows:
1 .化学腐蚀，主要是指烟道中有腐蚀性的介质在一定温度下与金属设备发生化学反响，生成可溶性铁盐，随时间的推移对设备产生腐蚀作用。
1. Chemical corrosion mainly refers to the chemical reaction between the corrosive medium in the flue and the metal equipment at a certain temperature, which generates soluble iron salts and corrodes the equipment over time.
2 .电化学腐蚀，这主要是指金属设备外表含水和电解质时，外表构成一次电池，产生电流，经过一段时间也会产生腐蚀作用。
2. Electrochemical corrosion, which mainly refers to that when the surface of metal equipment contains water and electrolyte, the surface forms a primary battery and generates current, which will also cause corrosion after a period of time.
3 .磨损腐蚀，主要是指烟道中残留固体颗粒，这些颗粒会停止与生物脱硫设备外表的摩擦，不时更新外表，加速与设备外表的腐蚀过程，使设备外表变薄。
3. Abrasion corrosion mainly refers to the residual solid particles in the flue. These particles will stop the friction with the surface of the biological desulfurization equipment, update the surface from time to time, accelerate the corrosion process with the surface of the equipment, and make the surface of the equipment thinner.
由此可见，生物脱硫设备的生产必须关注设备防腐性能的设计，这一环节在整个生物脱硫过程中也起着重要的作用。
It can be seen that the production of biological desulfurization equipment must pay attention to the design of equipment anti-corrosion performance, which also plays an important role in the whole biological desulfurization process.
