Difficulties in tail gas treatment of standby diesel generator set

When the standby generator operates under unstable conditions, it will produce polluted tail gas. If it is not treated, it will affect the quality of people's living environment.

The standby diesel generator set has huge exhaust flow, high exhaust flow rate and low exhaust temperature. Obviously, transplanting the vehicle diesel engine with small exhaust volume cannot achieve the expected effect. In the actual working scenario, it is difficult to remove the two main components PM and NOx in the exhaust gas of the fixed standby diesel generator set.

Black smoke treatment method of ceramic carrier (filter element) coated catalyst

The old model adopts wall flow ceramic filter element, which is sealed with carbon steel or stainless steel shell. The tail gas passes through the ceramic filter element to intercept and trap particles in the filter element. The relative back pressure is high, the unit has partial power loss due to improper selection and proportion, and it is difficult to clean the carbon deposit after blockage. In the later stage, the filter element needs to be replaced or removed for high-temperature sintering and back blowing. The filter element is vulnerable, and the treatment efficiency is 90%-95%.

New black smoke treatment method for standby diesel engine metal dry black smoke purifier

GRVNES grvnes-cyj heavy duty diesel generator set dry purifier aims at the black smoke at the first port of the diesel generator set during cold start and the pollutants discharged during operation, PM particles and Ringer blackness below grade I. The imported 316L alloy metal wire, brand-new material and process combination are adopted. The new dry exhaust gas purification and treatment device for heavy-duty diesel generator set, which is self-developed and has all intellectual property rights, is composed of multiple groups of metal DPF carriers in parallel, and adopts the snap fixed withdrawable unit design. The round handle can rotate 360 degrees, with large capture cross-sectional area and small back pressure. It has no loss on power. It can be disassembled and unitized design. Its weight is only 52% of the old model. The filter element can be flexibly extracted and washed for regeneration. The later maintenance is convenient and fast. The stainless steel box has a long service life and has a noise reduction function of 10-15 dB. The treatment efficiency is above 98%.
