Description

A kind of tunnel ventilation treatment facilities and ventilation cleaning method thereof
Technical field
The present invention relates to a kind of tunnel ventilation treatment facilities, be specifically related to a kind of tunnel ventilation treatment facilities and ventilation cleaning method thereof, belong to tunneling technique field.
Background technology
The structure in tunnel comprises main building thing and auxiliary device two parts.Main building thing is made up of barrel and portal, and auxiliary device comprises refuge chamber, fire fighting device, emergency communication and guarded drainage facility, and major long tunnel also has special ventilation and lighting apparatus.
As Patent publication No CN202047855U discloses a kind of Tunnel Ventilation System, comprise the tunnel ventilation device be arranged on tunnel inner wall, tunnel ventilation device comprises air-intake device and exhaust apparatus, the blower fan that air-intake device comprises housing, is arranged on the filter above housing and is arranged on above filter, the arc that exhaust apparatus comprises base plate, the top board be connected with base plate and is connected with top board, base plate, top board and arc surround a cavity for ventilating, and described housing is communicated with cavity.This Tunnel Ventilation System has had significant raising than traditional mechanization air vent mode ventilation effect, improves safety coefficient, decreases noise pollution, energy-conserving and environment-protective.
And for example Patent publication No CN201963328U discloses the urban tunnel ventilation system of the design of a kind of city tunnel and axial flow blower inclination installation form, belong to blower fan and ventilating system field of engineering technology, comprise tunnel ventilation well, the upper end of described tunnel ventilation well is vertical section, lower end is tilting section, in vertical section, silencer is installed, be provided with water-proof fan in tilting section, the gutter channel simultaneously the least significant end side of tilting section and tunnel wall offered connects.The utility model can solve the problem on rainproof, noise reduction and road surface, beautifying city effectively.
As Patent publication No CN102482943A discloses a kind of ventilating apparatus for tunnels, for purification comprises the air of the general tunnel internal in vehicle pass-through tunnel, contaminated for tunnel internal air is discharged to the outside simultaneously, tunnel internal ground arranges multiple water tanks that row vary in size at certain intervals, the contaminated hot-air produced by supply cold air and vehicle produces convection current, the coal smoke of wherein heavier-weight and tail gas are absorbed by water tank, the dusty gas of lighter in weight is discharged to the outside by chimney, tunnel internal air is made to remain pure and fresh, build comfortable tunnel environment, and in tunnel during breaking out of fire, fire water can be sprayed put out a fire.The present invention is the Natural Circulation realizing tunnel internal air, the convection phenomena produce water tank facility and chimney effect combine, make contaminated air Natural excrement, the present invention is different from the mode using ventilating fan to carry out ventilating in the past, noise can not be produced, also can not generate heat, and there is no power consumption, can economic loss be reduced.
And for example Patent publication No CN203114322U discloses a kind of ventilation device body.Described ventilation device body, comprises cable tunnel, it is characterized in that, the opening part of cable tunnel is provided with ventilation unit, and described ventilation unit comprises mounting seat, is provided with bearing block in mounting seat, bearing block connects main shaft, and bearing block surrounding arranges rotating vane.The air thermal convection current that the utility model is caused by natural wind and tunnel inside and outside temperature difference, promotes turbine and rotates, and realizes the running of round-the-clock, full weather conditions, remains that tunnel internal environment is good.And carried out the real-time detection of temperature, capacity and oxygen content by three groups of sensors, make maintainer grasp situation in tunnel at any time.Reduce the labour intensity of maintainer, ensure the health of human body of maintainer.
Under society high speed development, the private car that city dweller has gets more and more, and this just causes the crowded blocking of traffic.Particularly in urban road tunnel, this situation just seems especially serious.When wagon flow blocking or slow traffic, at this moment have accumulated a large amount of pernicious gases in passage, but tunnel is narrow, improper ventilation, often pile up many waste gas, dust, these pollute has serious harm to by the driver passenger in tunnel and passer-by.In the waste gas that automobile is discharged, containing the composition that carbon monoxide, sulfurous acid waste gas, nitrogen oxide, acetaldehyde, organic exhaust gas, lead compound etc. are harmful, the dense smoke that diesel vehicle is discharged also is obstructed the view.Various pernicious gas has spread effect to eyes and respiratory tract, is played various inflammation by endotracheal suction spasm, and the lighter is dizzy, headache, and severe one will be subject to permanent damage; Dust granules also can cause PUD D, makes to be difficult to ensure by the health of the personnel in tunnel.
Urban road tunnel is different from other road in city, and it is the section of a relative closure, and the tail gas of motor vehicle emission is easy to flock together, and is not easy diffusion.Certainly, for the urban road tunnel that some are shorter, when automobile travels in tunnel, produce various waste gas, also can be diffused in air along with natural wind and the automobile Piston Action Wind brought that flows, can not constitute a threat to driver and staff.But for the urban road tunnel that those length are very long, natural wind and traffic air relatively little to the metathesis of air in tunnel, the gas discharging substrate concentration in tunnel is difficult to control within allowable limit.
Common tunnel environment control technology adopts the means of ventilating.Because urban road tunnel ventilating system is extremely complicated, it has the features such as very strong time variation, non-linear and large time delay, and it is not good to the control effects of air quality in tunnel, not only expends the energy, improve the expense of tunnel operation, more cannot ensure the security of its environment.So, in order to ensure the health of people in the operation safety in tunnel and vehicle, study vehicle exhaust concentration in tunnel, study its processing mode, seek a kind of method of respond well control tunnel environment, become one of urgent problem in urban road tunnel construction.At present, the ventilation in tunnel is by installing large-scale air blast to realize substantially, and this noise is large, also very poor to long tunnel ventilation effect.
