A post-processing device for reducing the smoke of a high-power engine of a non-road mobile machine, comprising an intake air treatment chamber, an air outlet chamber, exhaust gas particulate matter purification cylinder I, exhaust gas particulate matter purification cylinder II, and a carrier unit; the intake air treatment chamber The sound insulation board I is divided into a front air processing chamber and a rear air processing chamber which are connected; The muffler pipe II connected by the pipe I; the air outlet chamber is divided into the front air outlet chamber and the rear air outlet chamber connected by the sound insulation board II; The rear air intake treatment chamber is connected to the rear outlet chamber through the exhaust gas particulate matter purification cylinder II; the exhaust gas particulate matter purification cylinder I and the exhaust gas particulate matter purification cylinder II are both equipped with carrier units for treating exhaust gas. The invention makes the purification efficiency of particulate matter higher, and effectively overcomes the adverse effect of fuel quality deterioration on emission.
Description
technical field [0001] The invention belongs to the technical field of engineering machinery, and in particular relates to a post-processing device for high-power engine smoke of non-road mobile machinery. Background technique [0002] Non-road National III emission standards and Tier 3 in the United States and Tier 3 in Europe have greatly lowered the limit value of exhaust pollutant particulate matter. With the development of domestic construction machinery, the proportion of sales in overseas markets is getting higher and higher, and the emission requirements are becoming more and more stringent. For high-power engines, it is no longer possible to meet the emission requirements of developed countries simply by adjusting the power curve and control procedures of the engine itself. Therefore, an external after-treatment device is required to purify the exhaust gas to meet the emission regulations. [0003] Since the non-road three-stage emission regulations only require the...
