摘要： A sprayer for settling dust of a coal mine includes: an outer housing, having at least one opening configured to spray water mist; a sprayer, placed in the outer housing, configured to spray water mist through the opening; a plurality of water curtain nozzles, configured to spray water curtain lines outside the opening to block suspended dust; and a support, configured to support the outer housing. The water curtain nozzles are in an equidistant arrangement around a center of the opening. A plurality of the water curtain nozzles are constructed such that the nozzles are all oriented toward the same point, to form a circular or conical water curtain.

摘要： A gas-liquid spray dust settlement system for a fully mechanized mining face includes an atomization humidification subsystem, a boundary mist curtain subsystem, and a dust mist recycling subsystem that are all arranged outside the fully mechanized mining face, where the boundary mist curtain subsystem includes high-pressure blade nozzles mounted to hydraulic supports. The atomization humidification subsystem includes a spray dust settler mounted to a rocker arm of a coal cutter and configured to spray water mist completely covering the high-pressure blade nozzle. The dust mist recycling subsystem includes a wind-water linkage dust remover mounted to a semi-encircling support base, arranged under the spray dust settler, and configured to collect the water mist sprayed by the spray dust settler.

摘要： The present invention relates to the field of dust settlement systems, and discloses a gas-liquid spray dust settlement system for a fully mechanized mining face. A gas-liquid spray dust settlement system for a fully mechanized mining face includes an atomization humidification subsystem, a boundary mist curtain subsystem, and a dust mist recycling subsystem that are all arranged outside the fully mechanized mining face, where the boundary mist curtain subsystem includes high-pressure blade nozzles mounted to hydraulic supports, the atomization humidification subsystem includes a spray dust settler mounted to a rocker arm of a coal cutter and configured to spray water mist completely covering the high-pressure blade nozzle, the dust mist recycling subsystem includes a wind-water linkage dust remover mounted to a semi-encircling support base, arranged under the spray dust settler, and configured to collect the water mist sprayed by the spray dust settler. Compared with the prior art, the dust settlement system according to this application can enhance a dust settling effect and effectively control a dust concentration of the fully mechanized mining face or even an entire mining area.
