Embodiment Construction
[0045] The road tunnel air dust removal and denitrification vehicle consists of tractor, dust removal compartment, denitration compartment, high voltage generator, electromechanical control cabinet, exhaust hood, electrostatic precipitator, dust removal compartment connection workstation, humidifier, denitrification device, denitration compartment connection workstation, automatic control system composition. The dust removal and denitration vehicle uses the principle of electric dust removal and the mechanism of activated carbon adsorption, and according to the characteristics of tunnel air purification, the fixed closed dust removal and denitrification method is expanded to the mobile open dust removal and denitrification method, and the movement of the gas relative to the dust removal and denitrification system is changed into a dust removal and denitrification system. Relative to the movement of the gas, the vehicle speed is used to control the wind speed, and the air volume...

The invention discloses an air dust-removing and denitration vehicle for highway tunnels. The vehicle comprises a traction vehicle, a semi-trailer carriage, an electric dust remover, a humidifier, a denitrator, an exhaust hood and an automatic control system, wherein the semi-trailer carriage is hooked with the vehicle tail of the traction vehicle; the electric dust remover, the humidifier and the denitrator are successively arranged in the semi-trailer carriage; the exhaust hood is arranged at the position of an air inlet, and is provided with a first working station for sealing the air inlet and a second working station for opening the air inlet; the automatic control system is used for automatically controlling the exhaust hood to exchange between the two working stations, and at the same time, the automatic control system is used for controlling the opening and the closing of the electric dust remover, the humidifier and the denitrator. The invention also discloses a method for removing dust and denitrating by using the air dust-removing and denitration vehicle for the highway tunnels. The air dust-removing and denitration vehicle has the advantages of simple structure, comprehensive functions, convenient operation, low cost, high efficiency and good effect, so that the air dust-removing and denitration vehicle is suitable for various highway tunnels.
Description
technical field [0001] The invention belongs to the field of environment-friendly air purification equipment, in particular to a road tunnel air dust removal and denitrification vehicle and a dust removal and denitrification method thereof. Background technique [0002] With the development of cities and the increasing demand for traffic, unprecedented road construction has led to a sharp increase in the number and length of road tunnels. As a relatively closed man-made space, tunnels have problems such as difficult air exchange between inside and outside, low visibility, noise and vibration, and frequent traffic accidents. [0003] Air pollutants in the tunnel mainly come from motor vehicle exhaust emissions and dust generated during driving. Exhaust emissions from vehicles include particulate matter (PM), nitrogen oxides (NOx) and other harmful substances. Particulate matter (PM) is a product of incomplete combustion of fuel, mainly from diesel vehicles, which can cause ...
