What is the working principle of desulfurization and denitration
Some customers want to know what the working principle of desulfurization and denitration is. Today, we will give you a brief introduction. Let's take a look.
The working principle of desulfurization and denitration refers to reducing the generated NOx into N2 to remove the NOx in the flue gas. According to the treatment process, it can be divided into wet denitration and dry denitration.
It mainly includes: acid absorption method, alkali absorption method, selective catalytic reduction method, non selective catalytic reduction method, adsorption method, ionomer huohua method, etc. some researchers at home and abroad have also developed a method of treating nitrogen oxide waste gas with microorganisms.
Desulfurization and denitration is simply a process of neutralizing acid with alkali. Desulfurization is to remove sulfur dioxide and nitrogen oxides contained in boiler flue gas by means of out of stock.
Desulfurization is a process using alkaline desulfurizer (such as limestone, calcium oxide, sodium hydroxide, etc.) The slurry is made and mixed with boiler flue gas. When sulfur dioxide meets water, it becomes acid and reacts with basic desulfurizer to generate sulfur and Suan calcium (sulfur and Suan calcium) and other desulfurization end products. The principle of denitration is similar to desulfurization, that is, ammonia or urea is used instead of denitration agent.
