Embodiment

[0027] Embodiment: An autonomous air purification system for a tunnel consists of a carrier vehicle 1, an on-board engine 7 (environmentally friendly), a booster pump 9, a front dust-repelling fog cannon 2, a dust-proof fog curtain 3, a dust-absorbing cover 4, a screen 11, a wind Chassis 5, filter box 6, decompression device 12, filter screen 13, dedusting agent silo 10, detector 14, etc., using dust isolation mist curtain 3 to isolate the treatment area and operation area, before starting the dust isolation mist curtain 3 at the same time Equipped with the dust blowing fog cannon 2, the dust can be reduced outside the machine. The waste gas is sucked into the filter box 6 by a fan for deep purification, and enters the filter cartridge through the filter screen 13 for dust removal and purification again, and is discharged after being tested. The invention adopts a combination of physical and chemical methods, sprays dust on the periphery, and uses dust suppressant and water mi...

Abstract

The invention discloses a tunnel dust removal system. The system comprises a filter box and a fan box; the inlet end of the filter box is connected with the fan box, the inner wall of the filter box is provided with nozzles which are spirally arranged, the nozzles are connected with a dustfall agent stock bin through a pressurizing pump, a treatment system which can move, and achieve active suction treatment, physical and chemical combination, deep dustfall and purification of air in the tunnel is adopted, the work environment can be improved within the short time, guarantee is provided for rapid construction, and the method is high in work efficiency, high in purification efficiency, low in cost, high in safety, convenient, easy to operate, and wide in application value.

Description

technical field [0001] The invention relates to an air purification system and method for tunnel construction. Background technique [0002] With the rapid development of engineering construction in our country, the construction of tunnel engineering is also speeding up, and long tunnels continue to appear. With the improvement of people's awareness of environmental protection and the deepening of the people-oriented concept, improving the operating environment of tunnel construction and ensuring operation safety have become the primary issues faced by engineering construction. Harmful gas and dust (general air dust, silt dust, coal dust, welding fume, blasting gas, equipment exhaust, etc.) produced in the tunnel during construction not only directly affects the improvement of labor efficiency, but also hinders visibility due to turbid air and interferes Mutual operation seriously restricts the construction progress, and at the same time causes damage to the facilities in t...
