工業尾氣脫硫的重要性

首頁- 新聞資訊 > 公司新聞

2021-08-25

隨著社會經濟化的高速度發展、工業化進程的進一步加快，導致工業進程中產生大量的氣態污染物（主要以含油漆、含硫、含氮、含氧的有機物或無機物），形成了工業廢氣。未經處理的工業廢氣排放到大氣中，會嚴重污染環境并影響附近居民的生活質量。例如，會使人感到不適，出現頭痛、頭昏、惡心、嘔吐、食欲不振和精神不集中等癥狀。另外，對人的呼吸系統、循環系統、消化系統和生殖系統也有影響。

With the rapid development of social economy and the further acceleration of industrialization, a large number of gaseous pollutants (mainly organic or inorganic substances containing paint, sulfur, nitrogen and oxygen) are produced in the industrial process, forming industrial waste gas. Untreated industrial waste gas discharged into the atmosphere will seriously pollute the environment and affect the quality of life of nearby residents. For example, it will make people feel uncomfortable, with symptoms such as headache, dizziness, nausea, vomiting, loss of appetite and lack of concentration. In addition, it also affects people's respiratory system, circulatory system, digestive system and reproductive system.

世界各國對煙氣脫硫都非常重視，已開發了數十種行之有用的脫硫技術，其中廣泛采用的煙氣脫硫技術有：石灰/石灰石—石膏濕法，具有適用煤種寬、原料廉價易得、脫硫率高（可達90％以上）等諸多優點，占據的市場份額，但投資和運行費用大，運行維護量大。

Countries all over the world attach great importance to flue gas desulfurization and have developed dozens of useful desulfurization technologies. Among them, the widely used flue gas desulfurization technologies are lime / limestone gypsum wet process, which has many advantages, such as wide applicable coal types, cheap and easy availability of raw materials, high desulfurization rate (up to more than 90%), and occupies a large market share, but it has large investment and operation costs and large amount of operation and maintenance.

脫硫催化劑的優點可以提高脫硫效率，無需進行設備擴容改造；節能降耗（省廠用電）；減少石灰石用量；提高燃煤調整和脫硫運行、備用的靈活性；增加石灰石的分散性，減少設備的結垢；提高氧化效率，減少亞硫酸根含量，提高真空皮帶機脫水效率等。

The advantages of desulfurization catalyst can improve desulfurization efficiency without equipment expansion and transformation; Energy saving and consumption reduction (saving auxiliary power); Reduce limestone consumption; Improve the flexibility of coal adjustment and desulfurization operation and standby; Increase the dispersion of limestone and reduce the scaling of equipment; Improve oxidation efficiency, reduce sulfite content, improve dehydration efficiency of vacuum belt conveyor, etc.

脫硫催化劑在工業中的用途有很多種，特別是對于現在的工業來說基本上都離不開它，而在鍋爐煙氣的處理中使用脫硫催化劑可以給我們的工業制造帶來很多方便。SO2污染已超過煙塵污染成為大氣環境的一大污染物。隨著世界各國工業化進程的不斷加深，煙氣脫硫（FGD）有別于其他脫硫方式是世界上大規模商業化應用的脫硫方法，是控制酸雨和SO2污染有用的和主要的技術手段。

There are many uses of desulfurization catalyst in industry, especially for the current industry, it is basically inseparable from it, and the use of desulfurization catalyst in the treatment of boiler flue gas can bring a lot of convenience to our industrial manufacturing. SO2 pollution has exceeded soot pollution and become a major pollutant in the atmospheric environment. With the deepening of industrialization in the world, flue gas desulfurization (FGD) is different from other desulfurization methods. It is a desulfurization method for large-scale commercial application in the world. It is a useful and main technical means to control acid rain and SO2 pollution.
