Description

TECHNICAL FIELD

[0001] The utility model relates to the field of transport vehicle tail gas purification technology, especially relates to a UQ type underground transport vehicle tail gas purification device. BACKGROUND

[0002] The technical measures for purifying automobile tail gas and reducing pollution influence include internal purification and external purification of the engine. The former is to make part of the exhaust gas burn again to reduce harmful substances in the exhaust gas, and the latter is to install a tail gas catalytic purifier. Carbon monoxide, hydrocarbons and nitrogen oxides and other exhaust gases discharged from the internal combustion engine are converted into carbon dioxide, nitrogen and water through the catalytic purifier.

[0003] In the underground mining industry, mainly uses the transport equipment to be the rail transport or the trackless transport, the belt transport and so on several ways. The mine dump truck is a common and flexible transport mode in trackless transport of mine, but when the tail gas treatment of mine dump truck is not up to standard, it will seriously affect the air quality in the mine and endanger the occupational health of employees and other problems. In the use process, a UQ type mine dump truck tail gas purification device uses high temperature of engine exhaust gas to atomize water to purify harmful gases (CO, NO) in generator exhaust gas and carbon particles generated by insufficient combustion of fuel. Since the tail gas treatment device of this type has poor fog effect when the exhaust gas temperature of the engine is not high, the tail gas purification is not complete, which affects the underground production environment. At the same time, in the process of running, the internal pressure formed by the exhaust emission expels the water in the tail gas purification device outside the purification device, which causes the water level to drop and cannot form good atomization and purification operation, so frequent water addition is needed. Frequent water addition in the purifier, the heat of the vehicle exhaust gas cannot heat the water in the purification to boiling state to form steam atomization to achieve purification effect, which causes the emission of harmful gas and carbon particles of the vehicle to be seriously over standard during the running of the vehicle in the underground roadway, causing the air in the mine to be seriously polluted by the tail gas of the vehicle.
