Wet type coal dust removing experimental system

Abstract

The invention discloses a wet type coal dust removing experimental system, and relates to the technical field of the mining industry exploitation. A dust removing effect can be effectively improved through the way of arranging top dust removing and side mist-spray dust removing, and an inclination arrangement angle of the side spray in the coal mine dust removing is researched, the parameter sizeof the mist-spray dust removing and the water-spray dust removing can be researched and analyzed to improve a dust removing effect; a field coal dust production problem can be simulated in a gravity falling way through the device, thereby guaranteeing the truth of a simulation experiment and improving the simulation effect, and the height difference can be adjusted as required; by arranging the system as a tunnel structure, the internal condition of the tunnel can be really simulated, the transferring point height, the water spray amount and the water spray height can be controlled, an appropriate mounting location and reasonable water spray amount can be found for a dust removing device at the transferring point through the method of controlling the variables, thereby reducing the water content of the coal while improving the dust removing effect, and then improving the quality of coal briquette.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a wet coal dust removal experimental system. Background technique [0002] With the development and progress of science and technology, the degree of automation of coal mining equipment is also increasing, so that the mining volume is also increasing, but the dust in the roadway is also increasing, and the dust is very harmful to human health and production safety. For example, when miners inhale dust for a long time, the mild ones will suffer from respiratory diseases, and the severe ones will suffer from pneumoconiosis, which seriously endangers human health. In addition, when the dust in the underground air reaches a certain concentration and there is a heat source that can cause an explosion, it may cause a coal explosion, which will pose a great threat to mine safety and production. At the same time, the dust will reduce the visibility of workers and accelerate mechanical wea...

AI Technical Summary

Problems solved by technology

Especially in the actual use process, the falling height of coal at different locations is different, and the content of coal dust produced is also different. It is necessary to adjust the water volume and water spray height, otherwise it will cause poor dust removal effect, or coal dust moisture content is too high
