Dry-wet separation combined mining belt conveyor transshipment dust remover and dust removal method

Abstract

The invention relates to a dry-wet separation combined mining belt conveyor transshipment dust remover and a dust removal method. The dust remover comprises a dry type dust isolation device, a power supply device and a wet type dust removal device which are sequentially communicated. The dry type dust isolation device comprises a dust isolation cavity and a dust collection flow guide cavity whichare communicated with each other; the dust isolation cavity is an L-shaped cavity with four closed sides and four opened sides; dry-wet separation of dust can be realized, and the process is independent and closed; the influence of the spraying process on the physicochemical properties of coal and rock materials and the air humidity of a working space can be effectively avoided, the spraying waterconsumption and the sewage recycling amount can be greatly reduced through centralized spraying, and the beneficial technical effects of small negative influence, high dust removal efficiency, low operation cost, good environment-friendly performance and the like are achieved.

Description

technical field [0001] The invention relates to dust removal for reloading of a belt conveyor for mines, in particular to a combined dry and wet separation reloading dust collector for a belt conveyor for mines and a dust removal method. Background technique [0002] At this stage, mines at home and abroad widely use spray dust suppression methods to prevent, control and treat high-concentration dust pollution in the transfer area of ​​underground belt conveyors. Studies have shown that suspended dust particles can collide with fog droplets with a certain speed, intercept, condense and form dust-laden droplets, so as to achieve settlement under the action of gravity and reduce the dust concentration in the air. However, the existing transfer point spray dust suppression technology generally has the following deficiencies: [0003] (1) The fog field faces the coal and rock materials being transported. Excessive moisture will significantly affect the physical and chemical par...

Problems solved by technology

[0003] (1) The fog field faces the coal and rock materials being transported. Excessive moisture will significantly affect the physical and chemical parameters such as the water content of the coal and rock materials, resulting in significant changes in the properties of the materials;

[0004] (2) The fine mist particles produced by the nozzle are suspended in the air of the workplace for a long time, resulting in high humidity in the production environment and discomfort for the workers;

[0005] (3) The underground reloading area is an open space. In order to improve the dust suppression efficiency, it is necessary to increase the spray range and spray water consumption. This will greatly increase the production cost and the dust removal sewage cannot be recycled and treated in a centralized manner, causing secondary pollution to the operating environment.
