Pollution level and visibility prediction methods of a longitudinal-flow type tunnel, and permitted pollution level and visibility maintenance methods therefron

摘要

Contamination and visibility prediction method of the type formula road tunnel having a vertical ventilation gang and the electrostatic precipitator and the jet fan and passed through the tunnel by measuring the speed of the types of vehicles, vehicles, and the vehicle the vehicle will pass through the first half of the tunnel obtaining a pure CO gas, and the mass of particulate emissions in the tunnel and, the total amount of pure CO gas and smoke by using a mass of the pure CO gas and fumes present in the moment tunnel front half where the (n + 1) th control period starts the obtaining step, and by setting the tunnel inlet and outlet parts of test surface, the (n + 1) th control period, and obtaining the CO concentration of the gas and the fumes of the end of the hour if the mobile checks the end of the n + 1 second control period ends and the moment to obtain a CO gas concentration and the soot density of the vertical ventilation phase update section, to obtain the concentration of CO and the exhaust gas discharged through the vertical ventilation gang System and, CO gas concentration of the predetermined distance and the step of obtaining a CO gas and the exhaust amount of the transfer to the second half of the tunnel using the CO gas to the soot amount and the CO gas concentration and soot concentration obtained by the respective steps from the tunnel exit portion and it comprises the step of obtaining the soot concentration.
