In Shanghai, a vibrant international metropolis, the exhaust gas denitrification of backup generator sets by communication operators plays a crucial role in ensuring stable power supply as an important power source. Whether it is a sudden power failure or a temporary power demand in special occasions, the backup generator set can be quickly put into use to ensure the normal operation of various activities. However, the environmental pollution caused by its exhaust emissions cannot be ignored. Green Valley Environmental Protection has undertaken a challenging generator set exhaust treatment project with professional strength and innovative technology. This project is aimed at 24 mobile generator sets equipped with Weichai 12M55D2450E310 engines, with a displacement of 65.65L, and has carried out a series of effective work.
After in-depth research, Green Valley Environmental Protection has decided to adopt selective catalytic reduction (SCR) denitrification technology as the core treatment core, using a certain amount of urea as a reducing agent to selectively reduce nitrogen oxides (NOx) in exhaust gas to nitrogen and water at a certain temperature. The denitrification efficiency is extremely high. Green Valley Environmental Protection’s exhaust treatment system has carefully planned the system layout to ensure perfect compatibility with Weichai 12M55D2450E310 engine, achieving precise treatment of exhaust gas from each generator set.
Green Valley Environmental Protection provides precise design and installation locations to ensure efficient collection and treatment of exhaust gas without affecting the normal operation of the generator units. The entire treatment system’s pipeline connections, circuits, etc. are carefully debugged to ensure the stability of the system operation. For the 24 generator units involved in the project, installation and precise debugging are guided to minimize the use of generator units and ensure the efficient operation of the project.
Project: Exhaust gas denitrification of a backup generator set of a communication operator in Shanghai
Match type: SCR
Brand and model: Weichai 12M55D2450E310 * 24 units
Displacement: 65.65L
Model: GRVNEC100-TX-24
NOx decreased from 2550mg/m3N to 150mg/m3
Through the unremitting efforts of the Green Valley Environmental Protection team, the project has achieved remarkable results. In terms of exhaust emission indicators, the NOx concentration has been significantly reduced from 2550mg/m3N to 150mg/m3, far exceeding the industry’s average treatment level. It not only meets the strict environmental emission standards in Shanghai, but also makes outstanding contributions to the city’s air quality.
