隨著社會經(jīng)濟(jì)化的高速度發(fā)展、工業(yè)化進(jìn)程的進(jìn)一步加快,導(dǎo)致工業(yè)進(jìn)程中產(chǎn)生大量的氣態(tài)污染物(主要以含油漆、含硫、含氮、含氧的有機(jī)物或無機(jī)物),形成了工業(yè)廢氣。
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.
未經(jīng)處理的工業(yè)廢氣排放到大氣中,會嚴(yán)重污染環(huán)境并影響附近居民的生活質(zhì)量。例如,會使人感到不適,出現(xiàn)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(tǒng)、循環(huán)系統(tǒng)、消化系統(tǒng)和生殖系統(tǒng)也有影響。
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 can make people feel unwell, 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.
世界各國對生物脫硫都非常重視,已開發(fā)了數(shù)十種行之有效的脫硫技術(shù),其中廣泛采用的煙氣脫硫技術(shù)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(dá)90%以上)等諸多優(yōu)點(diǎn),占據(jù)大的市場份額,但投資和運(yùn)行費(fèi)用大,運(yùn)行維護(hù)量大。
Countries all over the world attach great importance to biological desulfurization and have developed dozens of effective desulfurization technologies. Among them, the widely used flue gas desulfurization technology is lime / limestone gypsum wet method, which has many advantages, such as wide application of coal, cheap and easy availability of raw materials, high desulfurization rate (up to more than 90%), and occupies the largest market share, but the investment and operation cost are large, Large amount of operation and maintenance.
脫硫催化劑的優(yōu)點(diǎn)可以提高脫硫效率,無需進(jìn)行設(shè)備擴(kuò)容改造;節(jié)能降耗(省廠用電);減少石灰石用量;提高燃煤調(diào)整和脫硫運(yùn)行、備用的靈活性;增加石灰石的分散性,減少設(shè)備的結(jié)垢;提高氧化效率,減少亞硫酸根含量,提高真空皮帶機(jī)脫水效率等。
The advantages of desulfurization catalyst can improve desulfurization efficiency without equipment capacity 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 and improve dehydration efficiency of vacuum belt conveyor.
脫硫催化劑在工業(yè)中的用途有很多種,特別是對于現(xiàn)在的工業(yè)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(yè)制造帶來很多方便。SO2污染已超過煙塵污染成為大氣環(huán)境的大污染物。
Desulfurization catalyst has many uses in industry, especially for the current industry, which is basically inseparable from it. 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 the largest pollutant in the atmospheric environment.
隨著世界各國工業(yè)化進(jìn)程的不斷加深,
生物脫硫有別于其他脫硫方式是世界上唯一大規(guī)模商業(yè)化應(yīng)用的脫硫方法,是控制酸雨和SO2污染的為有效的和主要的技術(shù)手段。
With the deepening of industrialization in the world, biological desulfurization is different from other desulfurization methods. It is the only large-scale commercial desulfurization method in the world. It is the most effective and main technical means to control acid rain and SO2 pollution.
