Description

Water film type dust filter

Technical Field

The utility model belongs to the technical field of dust disposal equipment, concretely relates to water film formula dust filter.

Background

The operation such as welding and anchor spraying in the tunnel engineering construction process of small cross section can produce a large amount of dust, harm operating personnel health. Because the operation environment is a limited space, the smoke concentration can not be diluted, and the smoke can only be scattered to the vertical shaft along the tunnel, so that the smoke is diluted and settled in the discharging process. Although various dust filtering facilities are more in the market, the requirement of normal construction operation in a small-section tunnel cannot be met due to the limitation of the operation environment.

The most main measure of the existing engineering construction site dust fall measure is water spraying dust fall, namely, various water atomization devices are used for spraying water mist at a dust rising place, so that the dust fall effect is achieved. The method has to have reliable water supply and is generally adopted during earthwork construction. The operation of the small-section channel, particularly the operation of dust generation of a shallow-buried and underground-excavated tunnel mainly comprises the steps of spraying and anchoring concrete and welding, and the two operation steps are not suitable for a method of sprinkling water and reducing dust.

And the dust pollution source of tunnel construction can remove along with the construction progress, and industrial dust filtration system is difficult to in time make the adjustment, also is not suitable for tunnel construction.

The small-sized dust filter which is generally adopted in the construction site is mainly used for welding smoke filtration, dust is collected through a gas collecting hood and a fan, and clean air is discharged after the dust is filtered by a filter element. The filter element material of the equipment is made of non-woven fabrics, and the effect of filtering and drying dust is better. Girder wet cement particles are generated during tunnel shotcrete operation, and the filter element made of the material is destructive and cannot be cleaned once being contaminated. Such a small dust filter is also not suitable for use in trench service environments.
