Box type tunnel water curtain dust fall device

Abstract

The invention discloses a box type tunnel water curtain dust fall device. The device comprises a dust fall box and an exhaust fan which are connected through an air pipe, and the exhaust fan can convey dust-containing air into the dust fall box through the air pipe; a sprayer is arranged in the dust fall box; dust in the dust-containing air is captured through water spraying. The box type tunnel water curtain dust fall device has the advantages of being simple in structure, stable and reliable, high in operability, simple in processing method, rapid to use and the like; the dust can be directly controlled from the source, and the dust raising problem of a whole tunnel is thoroughly avoided. The device is remarkable in dust removal effect, the dust capture rate can reach 95-97%, and the device has extremely high popularization and application values.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, in particular to a box-type tunnel water curtain dust suppression device. Background technique [0002] At present, most of the tunnels in my country adopt the drilling and blasting method and mechanical excavation method, which will generate a lot of dust during construction. The construction of tunnel engineering is different from the construction of other projects on the ground. Good control is carried out through conventional measures, especially when mechanical excavation (milling and excavation method) is used, the working environment becomes extremely harsh during excavation operations, which will cause great harm to the construction workers and construction machinery on the tunnel face, and at the same time It also has a great impact on the rear operators, and there are certain safety hazards. It does not meet the requirements for civilized construction and does not meet the occ...

AI Technical Summary

Problems solved by technology

The use of this dust reduction method has the following disadvantages: 1. Although the dust concentration of the palm flour is reduced, the entire tunnel will be full of dust, and the civilized construction is poor; 2. After the entire tunnel is filled with dust, the visibility will decrease, and there are certain safety hazards. ; 3. Low working efficiency and high energy consumption, but when the tunnel is long, the dust removal effect is extremely poor; 4. When the tunnel is long, the ventilation and dust removal effect will be worse, which will cause dust to fall on the adjacent tunnel section or On other construction equipment, it not only affects the operation of other equipment, but also produces secondary pollution, resulting in incomplete dust removal, confusion on the construction site, etc.
