Problems solved by technology
[0008] The purpose of the present invention is to solve the problem of dust pollution in the existing underground mine shaft, and the existing technical solutions for dust control have high ventilation energy consumption, poor dust removal effect, large project investment, high construction risk, and difficult maintenance and management in the later stage. To solve the technical problems, it is necessary to provide a composite dust removal and purification system for the control of ore-drawing dust in underground mines with high dust removal efficiency, low energy consumption, low operating costs, simple structure, and easy installation.

The invention discloses a composite dust removal purification system for underground mine draw shaft ore drawing dust treatment. An atomizer (5) is arranged on a top plate above an ore drawing chamber(3) of a draw shaft; a dustproof sealing curtain (4) is vertically hung on a top plate above the ore drawing combined roadway where the ore drawing chamber (3) is located; a dust hood (6) is arrangedat the bottom of the dustproof sealing curtain (4) at the air outlet of the combined roadway of an ore pass; a wet dust removal fan is arranged in the downwind side direction of the middle roadway; an infrared sensor is installed on a top plate at the junction of a top plate above an ore drawing chamber (3) of the draw shaft and the dustproof sealing curtain (4); and the dust concentration sensoris installed below the ventilation and dust removal pipeline. A two-stage dust removal purification system of spray dust removal and wet dust removal fan purification is adopted, a dustproof sealingcurtain is used for sealing and blocking overflowing dust, and the dust removal device has the advantages of being high in dust removal efficiency, low in energy consumption, low in operation cost, simple in structure and convenient to install, and achieving ventilation and dust removal according to the air volume change according to needs.
Description
technical field [0001] The invention belongs to the technical field of industrial dedusting, and in particular relates to a dedusting system for an ore-drawing chute in an underground mine. Background technique [0002] Underground mines widely use chute to transport ore. In the underground production process of mine, chute is an important channel for ore lifting and transportation. Especially when the underground ore is unloaded with multiple middle-section high chute shafts, the loose ore is restricted by the shaft wall, which produces a movement similar to that of a piston during the falling process. Due to the large ore-drawing head height, the air in the chute is compressed sharply, and the ore is in the process of falling. Strong impact wind pressure is generated, resulting in a large amount of dust-laden airflow gushing out from the mouth of the ore unloading branch, causing serious air pollution in the underground unloading chamber and the unloading roadway, and ofte...
