. Greenlink purification SCR denitrification system introduction
The common harmful substances in the exhaust of diesel generator sets are black smoke and nitrogen oxides exceeding the standard, the main component of black smoke is not completely burned carbon particles; the source of nitrogen oxides is the nitrogen and oxygen in the air produced in the process of engine compression work. These two types of substances are one of the main components of air pollution, but also harmful substances that affect people's health. Therefore, the main goal of environmental protection in the engine industry is to control black smoke, nitrogen oxides, hydrocarbons and other harmful substances in the exhaust gas. Leelool focuses on the treatment of engine exhaust and industrial organic waste gas, and its main products are independently developed and have passed the ISO9001 quality system certification, which gives it a unique advantage in the generator set exhaust treatment industry.
Selective catalytic reduction (SCR) of diesel exhaust NOx control, the use of NH3 or urea (usually used in the mass ratio of 32.5% of the aqueous solution of urea) as a reducing substance, in the O2 concentration is higher than the NOx concentration of more than two orders of magnitude under certain conditions, under certain temperatures and catalysts, the use of NH3 to NOx reduction to N2 and H2O, due to NH3 high Due to the high selectivity of NH3, NOx is preferentially reduced without reacting with O2 first, so it is called "selective catalytic reduction". The excess NH3 is coated with a certain proportion of ammonia escape catalyst (ASC) at the end of the SCR carrier to ensure that NH3 reacts with O2 to generate N2 and H2O, avoiding secondary pollution caused by NH3 leakage.
The workflow of Leelool engine flue gas SCR denitrification system
The Leelool technology team, through the practice of matching with many world famous engines, high-precision sensors, exclusively designed electrical system and the world's top electrical components to match, the implementation of precise collaboration to ensure that the NOx and NH3 processing efficiency of the SCR and ASC system to meet the high standards of the world's stringent emission standards. 95% or more of the NOx management efficiency. The use of automotive urea pump injection ensures that urea solution consumption is kept at a low level. The control system has a built-in cloud communication system to provide real-time pollutant emission indicators after treatment; it can also be connected to the DCS system of the power station.
Control system interface and SCR denitrification system components
Greenlink purification SCR denitrification system controller interface, can clearly read the real-time intake and exhaust data, to master the urea use of the situation
Green Union purification SCR denitrification system components: urea tanks, air compressors, control systems, etc.
