Description
Technical field
The invention belongs to tunnel ventilation technical field, lead to particularly to a kind of multiparameter tunnel based on rate of discharge and concentration
Wind control method.
Background technology
Urban road tunnel does not destroys ground landscape owing to having, does not isolate down town, can reduce motor-vehicle tail-gas edge
The advantages such as the impact on surrounding are discharged on way, are more and more applied in city.
In order to ensure the operation security in tunnel, effective ventilation is essential.Tunnel ventilation includes that gravity-flow ventilation and machinery lead to
The big class of wind two, force ventilation includes that full transversal ventilation, semi-transverse ventilation, Longitudinal Ventilation and combination type ventilate.From the world
Development trend is seen, by single hole is two-way, the tunnel mode that is open to traffic generally develops into that double hole is unidirectional is open to traffic, i.e. tunnel be divided into up and under
2 hole bodies of row, vehicle one-way traffic in each tunnel, the change of this mode that is open to traffic makes longitudinal ventilation become tunnel
The main way ventilated.During because using longitudinal ventilation, the traffic air that vehicle motion is formed is identical with the wind direction of longitudinal ventilation,
The power that can make full use of ventilation by trattic power reduces force ventilation energy consumption.Typically, tunnel uses full jet blower time shorter
Formula longitudinal ventilation, i.e. utilize the relay effect of dispersed placement jet blower in tunnel and the comprehensive function of traffic air from
Tunnel enters portals air inducing, after dilution tunnel internal contamination gas, goes out portals from tunnel and discharges.But work as urban road tunnel relatively
Time long, pollutant concentrate discharge from going out portals, and rate of discharge is excessive, surrounding enviroment can be brought adverse effect, it is impossible to protect
The requirement of card " ambient air quality ", therefore, medium tunnel generally uses jet blower to combine with ventilation shaft
Stagewise longitudinal ventilation, the draft type of ventilation shaft mainly includes mechanical exhaust and machinery supply and exhaust two kinds.
Effective Ventilation Control is to realize tunnel normal operation and the important measures of ventilating system energy-saving run.Tunnel ventilation
The control mode of system mainly has direct control method, indirect control theory and fixed routine control methods three kinds.Direct control method is
The smokescope directly detected according to sensor and CO concentration value, utilize feedback controling mode to control the operation of ventilating system；
Indirectly control to be that the traffic flow conditions according to detection calculates smog and CO discharge capacity, utilize PREDICTIVE CONTROL mode to control to ventilate
The operation of system；Fixed routine control methods is the operation that temporally interval preprogramming controls ventilating system.
At present the control mode of urban road Tunnel Ventilation System mainly use for reference highway tunnel ventilation control model development and
Coming, but urban road tunnel is compared with traditional vcehicular tunnel, the hygienic requirements of operation stage is increasingly complex, simply
Indiscriminately imitate the ventilating controling mode of vcehicular tunnel and there is following two subject matter:
First, when having stricter environmental requirement near tunnel exit, it is impossible to ensure the environment shadow under the daily operation in tunnel
Ring in allowed limits.The core that urban tunnel ventilation system controls at present is all to ensure in hole for the purpose of sanitary standard,
And main control parameters is generally only smokescope and CO concentration, and for city tunnel, concentration to be considered limits
The requirement of value, also will be in order to avoid limiting rate of discharge the impact of environment." atmosphere pollution comprehensive discharge mark
Accurate " in for NOxRate of discharge propose stricter limit value, but universal in the control system of city tunnel at present
NO is not installedxConcentration sensor, this results in after design phase environmental evaluation passes through, in ventilating system actual motion not
There is substantive guarantee measure to NOxRate of discharge be controlled.
Second, when ventilation shaft uses force ventilation mode, when the axial flow blower of consentrated air supply and air draft puts into operation not
There is the quantitative basis of science, cause the waste of energy to a certain extent.For city tunnel, ventilation shaft is set
Main purpose is typically to avoiding out portals NOxRate of discharge too high and shunt.Due to current tunnel ventilation system
The control parameter of system is generally only smokescope (VI) and CO concentration, therefore in actual operation, it is impossible to according to NOx's
Rate of discharge determines central fan system should put into operation under which kind of operating mode, opens and there is certain blindness, and axle
The power of flow fan is far above jet blower, and this just inevitably results in the waste of energy.
Summary of the invention
The present invention solves technical problem present in known technology and provide a kind of based on rate of discharge and the multiparameter of concentration
Tunnel ventilation control method, the method is mainly for the demand in urban road tunnel, it is possible to ensure that ventilating system is full at the same time
Energy-saving run is realized on the premise of sanitary standard and environmental Kuznets Curves quality standard in foot hole.
The present invention solves that technical problem is adopted the technical scheme that present in known technology: a kind of based on rate of discharge
