  Some customers want to understand the working principle of desulfurization and denitrification. This editor will give you a brief introduction today. Let’s take a look.

The working principle of    desulfurization and denitrification is to reduce the generated NOX to N2 to remove NOX in the flue gas. According to the treatment process, it can be divided into wet denitrification and dry denitrification.

   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 to treat nitrogen with microorganisms. Oxide waste gas method.

   Desulfurization and denitrification is simply the process of neutralizing acid with alkali. Desulfurization is done by removing the sulfur dioxide contained in the boiler flue gas and removing the nitrogen oxides contained in the boiler flue gas by means of out-of-stock.

   desulfurization is a process of alkaline desulfurization agents (such as limestone, calcium oxide, sodium hydroxide, etc.). ) Is made into slurry and mixed with boiler flue gas. When sulfur dioxide meets water, it turns into acid, and reacts with alkaline desulfurizer to produce sulfur calcium (sulfur calcium) and other desulfurization end products. The principle of denitrification is similar to that of desulfurization, that is, ammonia or urea is used instead of denitrification agent.
