Embodiment 1

[0049] Such as figure 1 As shown, this embodiment provides a full-wet circulating water filter and dust removal system for roadway excavation working face, including fan 1, spray dust suppression system 2, rigid air cylinder 3, dust collection cover 4, monorail crane 5, belt conveyor 6, The mobile bracket 7 is nested on the top of the belt conveyor 6. The fan 1 and the spray dust suppression system 2 are fixedly installed on the mobile bracket 7. The fan 1 is connected to the air outlet of the spray dust suppression system 2 through the rigid air duct 3. The air inlet of the dust suppression system 2 is connected to the rigid air cylinder 3 and the dust collection cover 4 in turn, and the rigid air cylinder 3 is suspended on the top of the roadway through the monorail crane 5, and the whole system can be coordinated with the excavation process.

[0050] The spray dust suppression system 2 includes a box body 8, a baffle plate 9, a lower partition plate 10, a stirring unit, and...

Abstract

The invention discloses a full-wet circulating water filtration dust removal system for a tunnel roadway driving face and a working method, and belongs to the technical field of roadway driving face dust removal. The dust removal system comprises a water inlet system, a spray dust fall system, a power distribution system, a circulation system and a solid-liquid separation system; the spray dust fall system comprises a box body. The interior of the box body is partitioned into an air inlet zone and an air outlet zone through a baffle. Dust generated on the roadway driving face enters the air inlet zone, the air outlet zone is provided with an upper partition and a lower partition, a stirring zone is arranged between the upper partition and the lower partition, and a stirring unit is arranged in the stirring zone. The bottom of the box body communicates with the solid-liquid separation system. The circulation system is used for collecting water treated by the solid-liquid separation system and circularly spraying the water into the box body. The power distribution system supplies power to the stirring unit and the solid-liquid separation system. The dust removal effect is improved, meanwhile, waste of water resources caused by spray dust fall and pollution to the working environment are avoided, and recycling of water resources is achieved.

Description

technical field [0001] The invention belongs to the technical field of dust removal on roadway excavation working face, and in particular relates to a full-wet circulating water filtering dust removal system and a dust removal method on roadway excavation working face. Background technique [0002] In advanced coal-producing countries, roadheaders are the main equipment for tunneling in coal mines. The coal mine roadway excavation working face is a work place where dust generation is large and concentrated. The harm of mine dust is mainly manifested in two aspects. One is long-term inhalation of dust by the human lungs. The light one will cause inflammation of the respiratory tract, and the severe one will cause pneumoconiosis. In coal mines, it is manifested as silicosis, coal lung and coal silicosis. Occupational disease is the most harmful occupational disease to miners. The second is that in coal mines, coal dust will burn or explode under certain conditions, posing a ...
