Efficient dust removing system suitable for tunnel construction and using method

Abstract

The invention relates to the technical field of tunnel dust removing, in particular to an efficient dust removing system suitable for tunnel construction and a using method. The efficient dust removing system comprises five parts of a universal induced draft device, a dust filtering chamber, a dust removing exhaust fan, a power system and an operating platform. The universal induced draft device comprises a movable air suction hood, a ranging radar, a dust concentration sensor, a steel wire filter screen, a universal transmission device, a corrugated hose and a supporting frame. The dust filter chamber comprises a fan-shaped filter screen, a rotating control device, a filter screen cleaning chamber and a dust ash bucket. The dust removing exhaust fan is connected with the dust filtering chamber, provides power of air flow of the dust removing system, and receives a feedback signal of the dust concentration sensor to adjust power intelligently. The power system supplies power required by the universal induced draft device, the dust filtering chamber, the dust removing exhaust fan and the operating platform. The operating platform can control the universal induced draft device and dust filtering operation to complete dust suction and filtering work, and receives an early warning signal of the ranging radar.

Description

technical field [0001] The invention relates to the technical field of tunnel dust removal, in particular to an efficient dust removal system suitable for tunnel construction and a use method. Background technique [0002] According to the different geological conditions of the tunnels passing through the stratum and the development of the current domestic tunnel construction methods, the current tunnel construction in my country mainly includes various construction methods such as the drilling and blasting method and the boring machine method. Because the drill and blast method has many advantages such as simple construction method, wide geological adaptability, and low maintenance cost of construction equipment, it still occupies a dominant position in the construction method of mountain tunnels in my country. The basic process of drilling and blasting construction is to drill and blast the upper rock mass that retains the excavation space according to the cross-sectional ...

AI Technical Summary

Problems solved by technology

[0004] At present, tunnel dust removal often adopts ventilation dust removal method, water mist dust removal method, etc. The disadvantages of these methods are that the dust removal efficiency is low and the dust removal effect is not good, and the dust removal fan is always in a high-power operation state, resulting in a large waste of electric energy.

If the filter screen or filter element is used to filter dust, it is necessary to manually replace and clean the filter screen or filter element after the filter screen or filter element reaches filtration saturation, which greatly reduces the dust removal efficiency in the tunnel and directly affects the construction progress.
