Model number：L-DETX
Leelool SCR system adopts selective catalytic reduction (SCR) technology, has the characteristics of low operating cost, convenient installation, safe operation, and online real-time monitoring.
▍Product Introduction
Leelool L-DETX/L-GETX series diesel/gas engine exhaust denitrification system consists of a mixing pipe,control system,SCR reactor,gas storage tank,air compressor,injection system,and urea tank.Adopting selective catalytic reduction(SCR)method.According to the engine exhaust temperature,it is possible to choose to install a radiator or heater to ensure that the exhaust temperature entering the SCR denitrification system is within the active temperature range of the SCR catalyst,thereby effectively treating nitrogen oxides NOx in diesel/gas engine exhaust.Leelool SCR denitration system has the characteristics of low operating cost,convenient installation,safe operation,and online real-time monitoring.With years of research and practical experience,it has gained the trust and witness of many industry users.
▍Introduction to SCR Technology
Selective Catalytic Reduction (SCR) method uses ammonia gas or a 32.5% urea solution as a reducing substance to control the concentration of nitrogen oxides in diesel engine exhaust. Under conditions where the oxygen concentration is more than two orders of magnitude higher than the nitrogen oxide concentration, under certain temperature and catalytic action, ammonia is used to reduce nitrogen oxides to nitrogen gas and water vapor. Since ammonia preferentially reduces nitrogen oxides and does not react with oxygen, it is called "selective catalytic reduction". For excess ammonia, a certain proportion of ammonia escape catalyst (ASC) can be coated at the end of the SCR reactor to ensure that ammonia reacts with oxygen to generate nitrogen and water vapor, avoiding secondary pollution caused by ammonia leakage.
