Diesel engines may produce a large amount of black smoke during operation, which contains carbon particles and other harmful substances that are not fully burned, causing a serious impact on air quality. Particulate matter (PM) in black smoke can enter the human respiratory system and increase the risk of respiratory and cardiovascular diseases, posing a serious threat to public health.
Diesel engine black smoke control is an important measure to reduce environmental pollution and improve air quality, in the combustion process, the generated black smoke is mainly composed of carbon particulate matter (PM), in order to effectively control and reduce diesel engine black smoke emissions, green Valley environmental protection provides advanced diesel engine black smoke purifier, These purifiers use efficient diesel exhaust dry particulate trapping technology, through the way of physical filtration, to capture the particulate matter in the exhaust gas, at the same time, through the automatic bypass alarm system to ensure safe and reliable operation in the case of high back pressure, these purifiers can significantly reduce the diesel engine emissions of black smoke, improve the engine’s environmental performance.
Factors affecting the efficiency and lifetime of diesel particle traps (DPF) :
1, engine conditions: will affect the operating state of the engine, such as load, speed and operating temperature, will affect the DPF capture efficiency and regeneration frequency.
2. Regeneration strategy: When the DPF carbon particle catcher is blocked, we can make the particle catcher operate normally again through active regeneration and passive regeneration.
(1) Active regeneration: When the DPF unit is not removed, the high temperature generated by diesel injection combustion or the specially designed electric heater promotes the carbon combustion to achieve the purpose of cleaning up the carbon accumulation and restoring the working capacity;
(2) Passive regeneration: the particle catcher is coated with a special formula of precious metal catalyst, and at the right temperature, NO2 produced by DOC unit reacts with C in DPF;
The chemical equations for the removal of CO and HC in the DOC unit are as follows (main reaction equations) :
2NO+O₂=2NO₂
2CO+O₂=2CO₂
4HC+5O₂ =4CO₂+2H₂O
C+2NO₂=CO₂+2NO
C+O₂=CO₂
The solutions provided by Green Valley Environmental Protection include not only efficient black smoke purifiers, but also comprehensive technical support and after-sales service to ensure that customers can achieve the best black smoke treatment effect, to help enterprises meet the increasingly stringent environmental regulations, while improving corporate social responsibility and market competitiveness.
