Description
Technical field
The invention belongs to environment-friendly type air purification plant field, be specially a kind of traffic tunnel air dedusting denitration car and dedusting method of denitration thereof.
Background technology
Along with the development in city and the continuous increase of traffic demand amount, unprecedented road construction causes the quantity of highway tunnel and length to be sharp increase situation.As the artificial space of relative closure, tunnel exists inner air and outer air exchange and is difficult for, the problems such as low visibility and noise and vibration, and traffic accident takes place frequently.
In tunnel, airborne pollutant mainly come from the dust producing in automotive emission thing and driving process.Auto emission tail gas comprises the objectionable impuritiess such as particulate matter (PM), oxides of nitrogen (NOx).Particulate matter (PM) is the product of non-complete combustion of fuel, mainly from diesel-powered vehicle, can cause the chromosome aberration of blood lymphocyte, corpuscle (PM10, PM2.5) can go deep into lung respiratory system is caused to serious harm, particulate matter (PM) still affects the key factor of visbility in tunnel, directly the vision of chaufeur is debated to know and cause obstacle, and may cause operational vehicle generation safety misadventure.To human body and tunnel air environmental concerns maximum in oxides of nitrogen (NOx) is nitrogen dioxide (NO
2), NO
2be a kind of rufous gas, respiratory tract is had to strong impulse effect, suck after human body, hemoprotein Hb is combined in blood, and blood oxygen carrying capacity is declined, and can damage the organs such as heart, liver, kidney, very large on human body impact, meanwhile, and NO
2still produce acid rain, Los Angelos smog and cause climate change, produce the major cause of smog.
Because tunnel is hemi-closure space, along with the increase of length, hole inner air and outer air exchanges not in time, particulate matter (PM) and nitrogen dioxide (NO
2) existence easily cause in hole air quality to decline, have a strong impact on the environment in tunnel, driver and crew in tunnel and ventilating shaft discharge side periphery resident healthy caused to serious threat.A large amount of highway tunnel construction makes us be faced with very severe tunnel air pollution problem, the particulate matter in tunnel air pollutant and nitrogen dioxide (NO
2) administer very urgent.
At present, more and more for research and the application of tunnel air pollution control both at home and abroad, mainly with ventilation and exhaust purification, it is technological core, wherein tunnel ventilation is to adopt the outside method of introducing fresh air from tunnel, pollutants is carried out to physical dilution, and exhaust purification is by introducing functional attached purification plant, remove the airborne pollutant in tunnel, alleviate the impact of tunnel exhaust on the outer air environment of Tunnel.
Tunnel ventilation mode is divided into natural ventilation and mechanical ventilation.Natural ventilation is fresh air to be brought into a kind of ventilation type of tunnel dilution objectionable impurities by the piston action of driving vehicle, and little when the magnitude of traffic flow, more in short-term, tunnel adopts natural ventilation to meet the demands to length of tunnel.Mechanical ventilation is generally divided into transverse ventilation, semi-transverse ventilation and longitudinal ventilation mode, and when the magnitude of traffic flow is larger, when length of tunnel is longer, tunnel generally adopts mechanical ventilation mode.Tunnel ventilation generally adopts winds aloft tower or surface wind tower group, the mode exchanging by gas reduces air pollutant concentration in tunnel, yet do not purify owing to adding side line in long tunnel inside, after the pollutants high-altitude diffusion of discharging, can cause regional pollution, jeopardize the healthy of wind tower periphery resident, in addition, in inner city, build winds aloft tower and surrounding landscape and be difficult to coordinate, destructible city look and feel.
Exhaust purification is at present domestic and international the most frequently used tunnel air improvement technology, mainly concentrates on tunnel dedusting and NO
2in the exploitation of purification techniques and application.Yet dedusting denitration device need to be arranged in tunnel with by-pass type, ceiling mounting type, vertical shaft type.In bypass is installed, the air polluting is passed through to the sickle-shaped equipment of a crescent moon tunnel by force, air-flow recharges after purifying, reduce resh air requirement demand, and there are enough space mounting gas processing assemblies, during maintaining, do not affect main channel wagon flow, in the situation such as catch fire, can continue 30 minutes smog of absorption by high efficiency.When objective condition does not allow to build side line and large-scale air purification apparatus chamber, purification plant is set at tunnel top, the method all has application in the tunnels such as Norway Hell, Nygards and Japanese Tokyo Bay.In vertical shaft type is installed, air is processed backward upper vertical shaft through the purifying station of level and is discharged, and can reduce fan energy consumption and the impact on exhaust outlet view, and the Festnings tunnel of Norway and M30 tunnel, Madrid are adopted in this way.
The construction of existing tunnel dedusting denitration technology need to occupy the huge underground space, and the cost that not only tunnel civil engineering drops into is excessive, and the operation and maintenance cost after dedusting denitration device place in operation is also very huge.Therefore, control and the improvement technology of the applicable traffic tunnel air pollutants feature of exploitation have very real meaning.
