Abstract
The invention relates to the technical field of tunnel dust removal, in particular to a tunnel dust removal method. Dust in a tunnel is treated and collected through dust removal equipment. The method comprises the following steps: 1, performing cleaning operation on the tunnel to clean waste residues in the tunnel; 2, jetting compressed air to the top and the sidewall of the tunnel for secondary dusting; 3, starting the dust removal equipment to treat and collect the dust in the tunnel. Dusty air is sucked by a fresh air machine, and dust in the dusty air is preliminarily adsorbed and filtered through a filter screen, and then is adsorbed and collected through an anion device and a liquid-phase labyrinth to obtain dustless air for exhausting from an exhaust pipe. According to the method, a liquid-phase labyrinth structure is adopted, so that the contact time of the air and liquid is prolonged; in addition, an anion device structure is matched to adsorb particulate matters into the liquid, so that dust removal effects are improved; simple structure, convenience for use and long service life are achieved, the dust and toxic gas are continuously and effectively treated, and the method is widely used for tunnel dust removal in various environments.
Description
Technical field
The present invention relates to tunnel dedusting technology field is and in particular to a kind of minimizing technology of tunnel dust.
Background technology
The structure in tunnel includes main building thing and auxiliary device two parts.Main building thing is made up of barrel and portal,
Auxiliary device includes refuge chamber, fire fighting device, emergency communication and guarded drainage facility, and major long tunnel also has special ventilation and illumination
Equipment.
Chinese patent publication No. cn202047855u discloses a kind of Tunnel Ventilation System, including being arranged on tunnel inner wall
Tunnel ventilation device, tunnel ventilation device includes air-intake device and exhaust apparatus, and air-intake device includes housing, is arranged on housing
The screen plate of side and be arranged on blower fan above screen plate, exhaust apparatus include base plate, the top board being connected with base plate and with
The arc that top board is connected, base plate, top board and arc surround one for ventilation cavity, described housing connected with cavity.
This Tunnel Ventilation System has significant raising than traditional mechanization air vent mode ventilation effect, improves safety coefficient,
Decrease noise pollution, energy-conserving and environment-protective.
Chinese patent publication No. cn201963328u discloses a kind of city tunnel design and axial flow blower tilts to install shape
The urban tunnel ventilation system of formula, belongs to blower fan and ventilating system field of engineering technology, and including tunnel ventilation well, described tunnel leads to
The upper end of ventilating shaft is vertical section, lower end is tilting section, is provided with acoustic filter, is provided with water-proof fan in tilting section in vertical section,
The least significant end side of tilting section is relative with the gutter channel opening up in tunnel wall simultaneously connects.This utility model can efficiently solve anti-
The problem of rain, noise reduction and beautifying city road surface.
Chinese patent publication No. cn102482943a discloses a kind of ventilating apparatus for tunnels, comprises vehicle pass-through tunnel for purifying
Contaminated for tunnel internal air, in the air of interior general tunnel internal, is discharged to the outside by road simultaneously, on tunnel internal ground
String multiple water tanks of different sizes are arranged at certain intervals on face, contaminated with what vehicle produced by supplying cold air
Hot-air produces convection current so as to the coal smoke of middle heavier-weight and tail gas are absorbed by water tank, and the dusty gass of lighter in weight pass through
Chimney is discharged to the outside, and makes tunnel internal air remain pure and fresh, builds comfortable tunnel environment, and occurs in tunnel
During fire, fire water can be sprayed and put out a fire.This invention is the Natural Circulation realizing tunnel internal air, by water tank facility
