Abstract

The invention belongs to the technical field of liquid ammonia evaporation devices and in particular relates to a liquid ammonia evaporator for flue gas denitrification. The liquid ammonia evaporatorcomprises a flue gas mechanism, a reaction mechanism, a heating mechanism, an intermittent circulating mechanism, a first evaporation mechanism and a second evaporation mechanism, wherein the lower end of a heating chamber is fixedly mounted on the lower surface in a reaction chamber; a heating pipe is inserted into and fixedly connected with a left end wall of the heating chamber; the upper surface in the heating chamber is fixedly connected with an abnormally-shaped pipe; the left end of the heating pipe is wound on and connected to the outer surface of a flue gas chamber; a first air vent is formed in a lower side wall of the abnormally-shaped pipe; a liquid inlet pipe is fixedly connected into a right wall of the upper end of the abnormally-shaped pipe; a hydrophobic membrane and a first check valve are fixedly connected into the first air vent and a connection ring is arranged at the outer side of the first air vent. The liquid ammonia evaporator provided by the invention is mainly used for solving the problem that an existing liquid ammonia evaporator needs to be externally connected with a heating source, the evaporation efficiency is not high and the evaporator cannot be combined with flue gas to carry out the denitrification as soon as possible.

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...
