Abstract

The invention discloses a design method of a heavy-duty diesel vehicle exhaust fine dust treatment device, and relates to the technical field of air dust removal and purification. The design method of the heavy-duty diesel vehicle exhaust fine dust treatment device of the present invention is: on the basis of inheriting the basic principle of existing bag-type fiber dust filter design, the heavy-duty diesel vehicle exhaust fine dust treatment device of the present invention is designed as The metal cloth bag structure with sand and gravel particles as the filter medium for exhaust gas and dust disposal enables the tail gas and dust to be treated to be trapped during the advancing process, forming a dense ash filter layer on the surface of the sand particles in the dust disposal and filtration wall, and the dust filter The thickness of the layer is controlled according to the needs, which will further trap the fine particles in the dust, so that the treated tail gas dust can meet the requirements of the National VI emission standard. Compared with the prior art, the present invention has outstanding substantive features and remarkable progress of novel technical scheme, reliable technology, no secondary pollution, energy saving and emission reduction, safety and environmental protection.

Description

technical field [0001] The invention relates to the technical field of air dust removal and purification, in particular to the technical field of a design method for a heavy-duty diesel vehicle exhaust fine dust treatment device. Background technique [0002] With the deepening of industrialization and urbanization, the increase in the consumption of energy resources and the discharge of pollutants have caused serious air pollution, which has exceeded the carrying capacity of the earth and endangered the living environment and health of human beings. According to the bulletin issued by the Ministry of Environmental Protection, in 2014, the national automobile emissions were 29.427 million tons of carbon monoxide, 3.518 million tons of hydrocarbons, 5.789 million tons of nitrogen oxides, and 550,000 tons of particulate matter. 70% of the air pollution, and more than 90% of the particulate matter. Especially recently, motor vehicle pollution has become an important source of ai...
