Full-wet circulating water filtration and dust removal system and working method for roadway excavation working face

Abstract

The invention discloses a full-wet circulating water filtering and dust removal system and a working method of a roadway excavation working face, belonging to the technical field of dust removal on the roadway excavation working face. It includes water inlet system, spray dust suppression system, power distribution system, circulation system and solid-liquid separation system. The spray dust suppression system includes a box body. The inside of the box body is divided into an air inlet area and an air outlet area by baffles. The dust is passed into the air inlet area, and the upper partition and the lower partition are set in the air outlet area. There is a stirring area between the upper partition and the lower partition, and a stirring unit is arranged in the stirring area; the bottom of the box is separated from the solid and liquid. The system is connected; the circulation system is used to collect the water treated by the solid-liquid separation system and spray it into the tank; the power distribution system provides power to the stirring unit and the solid-liquid separation system. The invention improves the dust removal effect, avoids the waste of water resources and the pollution to the working environment by spraying and dust reduction at the same time, and realizes the recycling of water resources.

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 ...
