Abstract

The invention discloses a gas-liquid spraying and dust-falling system for a fully mechanized mining face, which belongs to the field of dust-falling systems. The gas-liquid spraying and dust-falling system for the fully mechanized mining face comprises an atomizing and humidifying sub system, a boundary mist curtain sub system and a dust mist recycling sub system, which are arranged at the outer side of the fully mechanized mining face, wherein the boundary mist curtain sub system comprises a high-pressure knife shaped spray nozzle mounted on a hydraulic bracket; the atomizing and humidifyingsub system comprises a spraying dust faller which is mounted on a rocker arm of a coal mining machine, and sprayed water mists completely cover the high-pressure knife shaped spray nozzle; and the dust mist recycling sub system comprises a wind-water linked dust removal device mounted on a semi-surrounding type supporting base, and is arranged below the spraying dust faller for collecting water mists sprayed by the spraying dust faller. Compared with the prior art, the dust-falling system can improve dust-falling effect, and effectively controls dust concentration of the fully mechanized mining face, even the whole mining area.

Description

technical field [0001] The invention relates to the field of dust suppression systems, in particular to a gas-liquid spray dust suppression system for a fully mechanized mining face. Background technique [0002] The fully mechanized mining face is one of the main sources of dust in coal mines. With the development of coal mining technology, large-scale coal mining machinery has been widely used, which greatly increases the coal production. High-intensity coal mining produces high-concentration dust, which poses a great threat to the health of field operators. In addition, high concentrations of dust can also cause accidents such as dust explosions, which seriously endanger production safety. Therefore, how to minimize the dust concentration in the fully mechanized mining face has become an urgent problem to be solved. [0003] In the actual coal mining environment, the complex flow field distribution has become the main influencing factor of dust prevention and control. ...
