脱硫塔对工业废气进行脱硫处理的设备，以塔式设备居多，即为脱硫塔。脱硫塔开始以花岗岩砌筑的使用的最为广泛，其利用水膜脱硫除尘原理，又叫花岗岩水膜脱硫除尘器，或名麻石水膜脱硫除尘器。优点是易保护，且可通过制作不一样的除尘剂，一起到达除尘和脱硫（脱氮）的作用。如今跟着玻璃钢技能的开展，脱硫塔逐步改为用玻璃钢制作。比较花岗岩脱硫塔，玻璃钢脱硫塔成本低、加工简单、不锈不烂、重量轻，因而变成今后脱硫塔的开展趋势。
Desulfuration tower is the equipment for desulfuration of industrial waste gas, most of which are tower type equipment. The desulfurization tower began to use granite masonry the most widely. It uses the principle of water film desulfurization and dedusting, also known as granite water film desulfurization and dedusting device, or gneiss water film desulfurization and dedusting device. The utility model has the advantages of easy protection, and can achieve the functions of dedusting and desulfurization (denitrification) together by making different dedusting agents. Now with the development of FRP technology, the desulfurization tower is gradually made of FRP. Compared with granite desulfuration tower, FRP desulfuration tower has the advantages of low cost, simple processing, rust free, light weight, so it becomes the development trend of desulfuration tower in the future.
另外316L不锈钢具有耐腐蚀、耐高温、耐磨损三大优势，也是脱硫塔开展重要趋势之一。经过多年的改进，已开展成文丘里型、旋流板型、旋流柱型、浮球型、筛板型、气动乳化型等各种类型的脱硫塔，设备技能日趋老练，各有优点和缺乏，公司可依本身需求选用不一样类型。
In addition, 316L stainless steel has three advantages of corrosion resistance, high temperature resistance and wear resistance, which is also one of the important trends of desulfurization tower development. After years of improvement, various types of desulfurizer have been developed, such as written Qiuli type, swirl plate type, swirl column type, floating ball type, sieve plate type, pneumatic emulsification type, etc. with increasingly sophisticated equipment skills, each has its own advantages and disadvantages. The company can choose different types according to its own needs.
