干式脫硝和濕式脫硝哪個更適合工業(yè)廢氣？

工業(yè)生產(chǎn)中，必然會產(chǎn)生廢氣，這些廢氣若不經(jīng)過處理便排放到空氣中勢必會對環(huán)境造成影響。其中氣態(tài)性廢氣是工業(yè)廢氣中種類多也是危害性大的。目前氣體性廢氣主要有含氮有機廢氣、含硫廢氣以及碳氫有機廢氣。

In industrial production, waste gas is inevitably generated, and if these waste gases are discharged into the air without treatment, they will inevitably have an impact on the environment. Among them, gaseous waste gas is the most diverse and harmful industrial waste gas. At present, gaseous waste gas mainly includes nitrogen-containing organic waste gas, sulfur-containing waste gas, and hydrocarbon organic waste gas.

（1）含氮廢氣。此類廢氣會對空氣組分造成破壞，改變氣體構成比例。尤其是石油產(chǎn)品的燃燒，在工業(yè)生產(chǎn)中石油產(chǎn)品的燃燒量巨大，而石油產(chǎn)品中氮化物含量大，因此廢氣中會含有大量氮氧化物，若排放到空氣中會增加空氣氮氧化物含量，對大氣循環(huán)造成影響。

(1) Nitrogen containing waste gas. This type of exhaust gas can cause damage to the air components and change the proportion of gas composition. Especially in the combustion of petroleum products, the combustion volume of petroleum products in industrial production is huge, and the nitrogen content in petroleum products is high, so the exhaust gas will contain a large amount of nitrogen oxides. If discharged into the air, it will increase the content of nitrogen oxides in the air, which will affect the atmospheric circulation.

2）含硫廢氣。含硫廢氣會對人們的生活環(huán)境造成直接危害，這是由于其同空氣中的水結合能夠形成酸性物質，引發(fā)酸雨。而酸雨會對植物、建筑以及人體健康造成損害，尤其會影響人的呼吸道。另外還會對土壤和水源造成影響，造成二次污染。

2) Sulfur-containing waste gas. Sulfur containing waste gas will cause direct harm to people's living environment, because it can combine with water in the air to form acidic substances and cause acid rain. Acid rain can cause damage to plants, buildings, and human health, especially affecting the respiratory tract. In addition, it will also have an impact on soil and water sources, causing secondary pollution.

（3）碳氫有機廢氣。該類廢氣統(tǒng)稱烴類，是一種有機化合物，主要由碳原子和氫原子構成。此類廢氣擴散到大氣中會對臭氧層造成破壞引發(fā)一系列問題，影響深遠。例如臭氧層破壞會加重紫外線的照射，而紫外線會對人的皮膚造成傷害，引發(fā)各類健康問題。另外紫外線照射度的改變也會對生態(tài)系統(tǒng)以及氣候造成影響。

(3) Hydrocarbon organic waste gas. This type of exhaust gas, collectively known as hydrocarbons, is an organic compound mainly composed of carbon and hydrogen atoms. The diffusion of such exhaust gases into the atmosphere can cause damage to the ozone layer, leading to a series of problems and far-reaching impacts. For example, the destruction of the ozone layer can exacerbate ultraviolet radiation, which can cause damage to human skin and cause various health problems. In addition, changes in UV exposure can also have impacts on ecosystems and climate.

煙氣脫硝技術是將煙氣中SOx進行分離，轉化為一種長期穩(wěn)定、不對周邊環(huán)境造成二次污染的物質的方法。

Flue gas denitrification technology is a method of separating SOx from flue gas and converting it into a long-term stable substance that does not cause secondary pollution to the surrounding environment.
