Abstract

The invention discloses a multi-stage combined tunnel dust removal system and a dust removal method thereof. The dust removal system includes a first-level dust removal device, a second-level dust removal device, a third-level dust removal device, a sedimentation filter tank and a water storage device; the first-level dust removal device includes The first-level dust removal outer cylinder, the air intake cylinder and the rotary dust removal mechanism. The inlet of the air intake cylinder is provided with an air intake grid; the rotary dust removal mechanism includes the first-level dust removal inner cylinder, a turbo fan, a water mist injection mechanism and a rotary power transmission mechanism; The first-level dust removal device includes the second-level dust removal tube, U-shaped tube and tubular condenser; the third-level dust removal device includes the third-level dust removal tube, corona electrode, filter bag filter and rectifier power supply, and the filter bag filter includes the dust removal skeleton And the dust filter bag, the three-stage dust removal cylinder is equipped with a blowback pipe, and there are multiple pulse blowback valves on the blowback pipe. The invention is novel and reasonable in design, convenient in realization, capable of efficiently removing dust generated in tunnel construction, reducing harm to human beings, strong in practicability, good in use effect, and convenient for popularization and use.

Description

technical field [0001] The invention belongs to the technical field of tunnel engineering, and in particular relates to a multi-stage combined tunnel dust removal system and a dust removal method thereof. Background technique [0002] my country has become the country with the largest number of tunnels and the total mileage of tunnels. However, a large amount of free silica dust will be generated in the construction of trackless transport drilling and blasting tunnels, especially in the four processes of drilling, blasting, shotcrete and ballasting. The dust concentration is higher. Long-term inhalation of dust can easily cause pneumoconiosis. Therefore, in order to protect the health of tunnel construction workers and reduce the occurrence of pneumoconiosis, developing tunnel construction dust control technology has become an urgent priority. [0003] Kang Zhuangsu and others published the paper "Analysis of Ventilation Spray Dust Removal System in Tunnel Construction" in ...
