Abstract

The invention belongs to the technical field of liquid ammonia evaporators, and specifically relates to a liquid ammonia evaporator for flue gas denitrification, including a flue gas mechanism, a reaction mechanism, a heating mechanism, an intermittent cycle mechanism, a first evaporation mechanism and a second evaporation mechanism; The lower end of the heating chamber is fixedly installed on the inner lower surface of the reaction chamber, a heating pipe is inserted and fixedly connected to the left end wall of the heating chamber, and a special-shaped pipe is fixedly connected to the upper surface inside the heating chamber; the left end of the heating pipe is wound and connected to the flue gas chamber. The outer surface; the lower side wall of the special-shaped pipe is provided with a first air hole, and the upper right wall of the special-shaped pipe is fixedly connected with a liquid inlet pipe; the first air hole is fixedly connected with a hydrophobic membrane and a first one-way valve, Moreover, a connecting ring is provided on the outside of the first ventilation hole; the present invention is mainly used to solve the problem that the existing liquid ammonia evaporator needs an external heating source, the evaporation efficiency is not high, and at the same time, it cannot be combined with flue gas for denitrification at the first time.

Description

technical field [0001] The invention belongs to the technical field of liquid ammonia evaporation devices, in particular to a liquid ammonia evaporator for flue gas denitrification. Background technique [0002] Flue gas denitrification refers to the reduction of generated NOX to N2, thereby removing NOX in flue gas. According to the treatment process, it can be divided into wet denitrification and dry denitrification. Some researchers at home and abroad have also developed a method of using microorganisms to treat NOX exhaust gas. Since more than 90% of NOx in the flue gas discharged from the combustion system is NO, and NO is difficult to dissolve in water, the wet treatment of NOx cannot Use simple washing method. The principle of flue gas denitrification is to use oxidant to oxidize NO into NO2, and then absorb the generated NO2 with water or alkaline solution to achieve denitrification. For flue gas denitrification in thermal power plants, ammonia is mainly used as a r...
