Abstract

The invention discloses a tunnel construction dust and harmful gas absorbing and purifying system which comprises a dust collecting box, an electric power equipment box, a catalyst box, an alkaline reagent box, a drying agent box and a gas collecting box are sequentially and adjacently arranged on the outer side of the dust collecting box, and an air inlet hopper is arranged on the side face of the dust collecting box in a communicating mode. Multiple layers of vertical electrostatic dust collection grids are arranged in the dust collection box at intervals, an exhaust fan is arranged at the top of the electric power equipment box, the exhaust fan and the electrostatic dust collection grids are electrically connected with the electric power equipment box, and an air inlet of the exhaust fan communicates with the dust collection box; a gas outlet of the exhaust fan is connected with the catalyst box through a gas conduit; the catalyst box is connected with the alkaline reagent box through a gas conduit; the alkaline reagent box is connected with the drying agent box through a gas conduit; and the drying agent box is connected with the gas collecting box through a gas conduit. The purification system provided by the invention not only can adsorb and remove small particles such as dust, but also can purify and absorb harmful gas, and also overcomes the defect that the environment action of tunnel construction is limited.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and particularly relates to an absorption and purification system for tunnel construction dust and harmful gases. Background technique [0002] Tunnel construction dust and harmful gases are mainly generated in two aspects. On the one hand, the tunnel will produce harmful gases such as CO, CO2, nitrogen oxides (NOX), sulfide and dust during the blasting process; on the other hand, excavators and large Harmful gases CO, CO2, nitrogen oxides (NOX), hydrocarbons (CH) and sulfides emitted by the internal combustion engine of the slag truck. Due to the semi-enclosed structure of the tunnel, the continuous increase of dust and harmful gases from continuous construction has seriously affected the life, health and safety of the construction site personnel. [0003] Small solid particles such as dust have strong adsorption capacity. They can enter the human lungs with people's breathing, and ...
