Diesel engine tail gas automatic catalyzing and purifying device for large engineering machinery

Abstract

The invention discloses a diesel engine tail gas automatic catalyzing and purifying device for large engineering machinery. The diesel engine tail gas automatic catalyzing and purifying device for the large engineering machinery comprises a device shell, a solar cell panel, an exhaust pipeline and a climbing ladder, wherein lateral supports are arranged on the left side and right side of the device shell; a device cover plate is fixed to the outer side of the device shell through bolts; the solar cell panel is bonded and fixed to the outer side of the device cover plate; a device base is connected under the device shell; a grinding box body is welded and fixed over the device shell; a device box door is hinged and fixed to the outer side of the grinding box body; and an exhaust box body is welded and fixedly to one side of the grinding box body. According to the diesel engine tail gas automatic catalyzing and purifying device for the large engineering machinery, a bevel gear and an eccentric wheel are arranged, and the bevel gear is used for driving a grinding block to rotate at the same time, so that the grinding block conveniently crush granular materials, the materials conveniently catalyze and absorb exhausted tail gas, and the tail gas absorption and catalysis time of the purifying device is shortened.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to an automatic catalytic and purification device for diesel engine exhaust used in large-scale construction machinery. Background technique [0002] The chemical composition of diesel diesel is mainly a mixture of alkanes, olefins and additives. During the use of large-scale construction machinery, diesel generators are generally used to provide power for vehicles. During the combustion of diesel, the exhaust gas contains nitrogen oxides and carbon monoxide. , carbon dioxide, aldehydes and a large amount of black smoke during incomplete combustion. The automatic catalytic and purification device for diesel engine exhaust used in large-scale construction machinery is to purify the flue gas generated by diesel combustion. The cost accounts for a large proportion of the entire mechanical cost, so the toxic substances inside the flue gas are reduced, and the construction...
