Ship engine exhaust gas treatment

Nitrogen oxide in the exhaust gas of marine generator set is a gas formed by the oxidation of nitrogen in the cylinder at high temperature, which is mainly composed of nitric oxide and nitrogen dioxide. Green Valley environmental protection has developed a set of "grvnes" SCR denitration system for the treatment of nitrogen oxides in the waste gas discharged by marine generators after years of painstaking research. After special design, the system can still realize high-efficiency operation under the condition of unstable exhaust temperature and gas quality; Important parts can withstand the common impurities in landfill gas and ensure the long-term stable operation of the system.

Diesel power generation waste gas treatment

Nitrogen oxides in the exhaust gas of diesel generator set are gases formed by the oxidation of nitrogen in the cylinder at high temperature, mainly composed of nitric oxide and nitrogen dioxide. Green Valley environmental protection aims at the treatment equipment of PM (particulate matter) and NOx (nitrogen oxide) in the exhaust gas of diesel generator set. Green Valley company has developed the integrated design of particle trap and SCR denitration system. The particle trap is used to treat the PM (particulate matter) in the waste gas to make it meet the environmental protection standard; SCR denitration system aims at NOx (nitrogen oxide) in waste gas to make it meet local environmental protection standards (specific standards are customized according to customer requirements).

Denitration treatment of power plant

Selective catalytic reduction (SCR) is used to control NOx in diesel engine exhaust. NH3 or urea (usually urea aqueous solution with mass ratio of 32.5%) is used as reducing substance. Under the condition that O2 concentration is more than two orders of magnitude higher than NOx concentration, under the action of certain temperature and catalyst, NH3 is used to reduce NOx to N2 and H2O. Because NH3 is highly selective, NOx is preferentially reduced, It does not react with O2 first, so it is called "selective catalytic reduction". For excess NH3, a certain proportion of ammonia escape catalyst (ASC) is coated at the end of SCR carrier to ensure that NH3 reacts with O2 to generate N2 and H2O and avoid secondary pollution caused by NH3 leakage. The exhaust temperature after diesel engine or gas engine turbine is generally in the range of 300 ℃ to 500 ℃, which meets the temperature conditions required for medium temperature catalytic reaction. If the temperature after vortex is higher than 500 ℃, high-temperature catalyst shall be considered, and the system cost will increase in a certain proportion.
