Description
Technical Field
The invention belongs to the technical field of mine safety and environmental engineering, and particularly relates to an experimental device for simulating and measuring the underground dust-containing and tail gas air flow purification effect.
Background
The metal ore can adopt three modes of underground mining, adit mining and open-pit mining in the mining process, and when mineral resources are in a mountain, a well head is dug at the bottom of the mountain and adit mining is built. When the metal ore is transported out of the mine, belt transportation and rubber wheel truck transportation can be adopted, and when the width of the roadway is suitable, the rubber wheel truck becomes the first choice due to the characteristics of flexibility and convenience. However, the transportation of ore by rubber-tyred trucks is not without disadvantages, because the rubber-tyred trucks need to be powered by diesel oil as fuel when running in a mine mined in a adit, and the diesel oil becomes tail gas after being combusted and is discharged into a relatively closed space underground. In the process of frequent driving of the rubber-tyred transport truck in the roadway, dust on the ground and on the wall of the roadway is also lifted, so that the air flow of the roadway contains harmful substances such as dust, tail gas and the like. When the ventilation condition of the mine is limited, harmful substances such as dust, tail gas and the like in the air flow can diffuse in the roadway and are difficult to settle; meanwhile, when ventilation is limited, the oxygen content in the air is reduced, so that the combustion rate of diesel oil is reduced, harmful substance components in tail gas are increased, vicious circle is caused, and the harm to a human body is further increased.
The harmful substances in the tail gas of diesel engine combustion mainly include carbon smoke and NOx、CO、SO2At present, the mine enterprises mainly rely on the installation of a purification device outside an engine for solving the problem, but the device has the defects of unstable operation, high use cost, short period and the like. For the roadway air flow containing two hazardous substances of tail gas and dust, most mine enterprises adopt the mode that cloth bag dust removal and activated carbon tail gas purification devices are arranged at the working places of personnel at the same time, and the cloth bag dust removal and activated carbon tail gas purification devices are used for purifying the air flow at local places to improve the atmospheric environment. When the device is used on site, most of the devices are arranged according to experience, and how to arrange the devices quantitatively is not considered. At present, no experimental device capable of systematically and simultaneously measuring the dust removal effect of the cloth bag and the purification effect of the tail gas containing the activated carbon on the dust and the tail gas wind flow is available. Therefore, it is an urgent problem to establish a laboratory device for the above.
