Abstract
The invention relates to a generator emission scheme, in particular to a method for processing tail gas of a gasoline generating set. The method for processing the tail gas of the gasoline generating set comprises two improved steps of internal purification and external purification. The internal purification improvement comprises the following steps: the mixing ratio of gasoline and lubricating oil is adjusted, the diameter dimensions of the main jet and the idle jet of a carburetor are reduced, the diameter dimension of the main air jet is enlarged, and the position of a top piston ring groove of a piston is lifted to the one third part of the piston head. The external purification improvement comprises the following steps: the noble metal mixture of platinum, palladium and rhodium is adopted as a catalyst, and the carrier size and the carrier honeycomb density of a catalyst converter are adjusted. The method of the invention enables the gasoline generator improved by adopting the method to break through the technical barriers of tail gas emission, heavy metal residues in material, etc., and the contents of CO, (HC) hydrocarbon and NOX in the emitted tail gas are greatly reduced.
Description
Technical field
The present invention relates to a kind of generator emission scenary, especially the exhaust gas treating method of gasoline engine generator group.
Background technology
The limit value that three big discharge indexs are arranged in the gasoline engine generator group discharging tail gas: CO, hydrocarbon (HC), NO
X, its principal contradiction concentrates on HC and standard differs bigger, and the key that therefore solves the discharging of gasoline engine generator group is how to reduce HC.
HC is the general designation of hydrocarbon, it mainly results from following several aspect: the imperfect combustion of gaseous mixture: because the gasoline engine generator group is typical two-stroke single cylinder gasoline engine, there is scavenging process in two stroke engine, must there be the fresh gaseous mixture of part not burn and directly gets rid of outside the cylinder, so just form the too much reason of HC discharging; Combustion chamber, cylinder, piston and piston ring etc. locate to exist the dead angle: because gaseous mixture can't burn in the dead angle that above-mentioned parts are formed, finally discharge outside the cylinder with waste gas, so just produced the HC pollution; Ignition energy deficiency: because the Combinatorial Optimization of parts such as ignition coil, high voltage package, magneto, spark plug is bad, cause plug ignition energy shortage or interrupted igniting, like this imperfect combustion phenomenon should be arranged by the gaseous mixture that ignition is fallen, thereby produce HC; Lubricating oil: because the gasoline engine generator group is to adopt gasoline to mix with lubricating oil to keep engine running, lubricating oil pollutes thereby also will inevitably discharge the outer HC that brings of machine with unburnt gaseous mixture in lubricated movement parts like this.This mixed lubrication mode also is the main source that produces the HC discharging.
Summary of the invention
The objective of the invention is for the processing method of harmful substance contents such as hydrocarbon in a kind of tail gas that can reduce the gasoline engine generator group is provided.
For realizing purpose of the present invention, the exhaust gas treating method of the gasoline engine generator group that this specification provides comprises that two of emission controls by improving combustion and external purifications improve step.
Emission controls by improving combustion improves and comprises, the mixed proportion scope of adjusting gasoline and lubricating oil is 30-55 times, the main jet and the idle metering jet diameter dimension scope of dwindling carburetor are respectively Φ 0.65mm-Φ 0.70mm and Φ 0.35mm-Φ 0.45mm, enlarging main air quantity bore dia size range is Φ 1.200mm-Φ 1.250mm, and the top-ring groove position of improving piston is to 1/3 of piston top.
The mixing optimal proportion of adjusting gasoline and lubricating oil is 50 times, and the main jet and the idle metering jet optimum diameter size of dwindling carburetor are respectively Φ 0.68mm and Φ 0.40mm, and enlarging main air quantity bore dia optimum size is Φ 1.235mm.
External purification improves and comprises that catalyst is the mixture of noble metal platinum, palladium, rhodium, and bullion content is 30 gram/cubic feet in the catalyst converter carrier.The proportioning of metal mixture platinum, palladium, rhodium is 10: 5: 1.External purification improves and comprises that also the catalyst converter carrier dimensions is Φ 30mm * 60mm, and the carrier cellular densities is 250 orders.
The inventive method make to adopt the gasoline engine generator behind this method improvement break through in exhaust emissions, the material technology barriers such as heavy-metal residual, greatly reduces CO in the tail gas that gives off, (HC) hydrocarbon, NO
