The invention discloses a purifying exhaust structure for a road tunnel, which comprises a draught opening, a draught pipe communicated with the draught opening, a tunnel polluted air purifying device connected with the draught pipe, a fan connected with the tunnel polluted air purifying device, an exhaust pipe connected with the fan, and air exhaust opening communicated with the exhaust pipe. The structure overcomes the drawbacks of an exhaust airway and exhaust tower scheme and a tunnel opening direct polluted air exhaust scheme, radically solves the problem that the sites of the exhaust airway and exhaust tower for the road tunnel are difficult to select and the problem that the exhaust airway and exhaust tower for the road tunnel are unfavorable for landscape and greatly reduces the pollution of the tunnel to the atmospheric environment.
Description
Technical field
The present invention relates to a kind of tunnel air exhaust system, relate in particular to the contaminated air emission abatement system in a kind of roads and tunnels.
Background technology
Along with economic development, urban traffic contradiction becomes increasingly conspicuous, and intercity transport need is risen day by day, and roads and tunnels becomes an advantageous methods of transport solution contradiction, becomes the important component part of means of transportation.But, contain dust granules thing (PM), carbon monoxide (CO), hydrocarbon (HC) and nitrogen oxide (NO in the tunnel in the air because the tunnel is full-closed structure
X) wait pollutant.Particle PM in the tunnel air can cause the chromosome aberration of blood lymphocyte; CO combines with human body hemoglobin because of it, directly lowers blood band oxygen amount, makes the people headache, lethargic sleep, unbalanced sensation occur, can cause death during excessive concentration; HC meeting teratogenesis, carcinogenic, mutagenesis, and cause photochemical fog; NO
XCan damage vision, respiratory system, cause and suffocate, also can cause acid rain, cause photochemical fog.So,, will have a strong impact on the traffic safety of driver and crew in the tunnel and healthy as untimely discharging tunnel internal contamination air.
Up to now, the roads and tunnels that has been open to traffic, pollutant be the only ventilation system dilution by being provided with generally, though this can handle the tunnel internal pollution problem more effectively, but contaminated air still directly is disposed to and is caused secondary pollution in the atmospheric environment generally without purified treatment.General for the tunnel below the long 500m, regulation according to JTJ026.1 " highway tunnel ventilation illumination design standard " and DG/TJ08-2033 relevant specifications such as " roads and tunnels design specificationss ", normal, block under the operating mode, allow natural ventilation, contaminated air can directly be discharged from going out the hole.For the tunnel more than the 500m, when peripheral open, the tunnel face of its outlet when environment sensitive point (residential community, school, hospital, Office Area etc.) is far away, contaminated air can adopt the mode of all directly discharging from the hole.Do not allow tunnel portal directly to discharge under the condition of all contaminants at environment, can be by the exhaust blower of centralized collection tunnel internal contamination air be set, external environment requirement according to the hole, determine the amount of pollutant of hole discharging earlier, all the other most waste gas are concentrated by the air draft well, be discharged into by wind tower height sky and dilute pollutant in the atmosphere, also reduced the discharge amount of exhaust gas at hole simultaneously, make the outer sensitive spot of certain distance around wind tower and the tunnel face reach the requirement of relevant emission standards.
When a large amount of environment sensitive point is arranged around tunnel face and ventilating shaft, the wind tower, when adopting the empty discharging of wind tower height also can't solve the tunnel external environment to influence problem, especially Japanese abroad, occurred adopting electrostatic precipitator ESP, the removal of removing particle PM in the tunnel contaminated air only to account for NO
X5% NO
2Denitration purifying device.Japanese patent application JP4346852 and JP5015810 disclose two kinds of tunnel electrostatic precipitator respectively, according to demands such as the size in tunnel, Design of ventilation, institute's required airflows, take large-scale independent machine room arrangement, tunnel side line arrangement and tunnel top arrangement.Said apparatus is installed in the tunnel integrated air exhaust system, and contaminated air is through part pollutant (PM, NO
2) purify other NO, HC, SO
2Nuisance is unprocessed, still needs by air draft well, the empty discharging of wind tower height.
Because China's current mobility tail gas discharge standard is lower than the foreign standard same period, make tunnel endoparticle pollutant, CO, NO
XHigher with HC airborne concentration in the tunnel, exploitation is fit to the control and the improvement technology of China's air pollutants of roads and tunnels characteristics, to satisfy the demand of tunnel air pollutant discharging, is extremely necessary.
CN101455929A discloses a kind of high wind-speed tunnel air electric dust-collection system, comprise cleaning module, detection module and cleaning treatment module, the input of cleaning module and detection module all receives tunnel air, the cleaning treatment module is connected with the cleaning module that comprises fore filter, air distributor, electrostatic precipitator, trough filter and post-filter, wherein the input of fore filter receives tunnel air, and the output of post-filter is disposed to atmosphere.This device is mainly used in removes particulate pollutant.
CN101380539A discloses a kind of tunnel air pollutant purification apparatus, this device collection electrostatic precipitation, CO room-temperature catalytic oxidation, HC and NO
XAbsorption/catalytic purification is an one, specifically comprise: electrostatic precipitation module, the air circulation module, the three-effect catalysis module, control module, at least one cleaning module and at least one adsorption module, wherein: the input of electrostatic precipitation module receives tunnel air, the output of electrostatic precipitation module connects the input of cleaning module and the air inlet port of air circulation module respectively, the output of cleaning module connects the input of adsorption module, the output of adsorption module connects the exhaust opening of air circulation module and the input of three-effect catalysis module respectively, and the exhaust opening of the output of three-effect catalysis module and air circulation module directly is disposed to atmosphere.Be connected between this covering device and main tunnel, air channel, ventilating shaft, the wind tower, satisfied the requirement that tunnel air pollutant is administered preferably, the problem that air draft well, exhaust chimney are got rid of tunnel internal contamination air need be set but solve roads and tunnels.
In sum, in the prior art, do not allow under the direct exhaust emission conditions of air of roads and tunnels mouth, need that still the air draft well is set, exhaust chimney is got rid of the contaminated air in the tunnel, and atmospheric environment, view are brought adverse effect at environment.Therefore, being badly in need of a kind of roads and tunnels of exploitation does not have air draft well, exhaust chimney purification air draft structure, can overcome the deficiency that existing tunnel is provided with air draft well, the direct exhaust emission air of exhaust chimney scheme and hole scheme.
