Embodiment Construction

[0032] see Figure 1~4 , in an embodiment of the present invention, a wet coal dust removal experimental system includes a protective seat cover 00, a sensor seat 01, a coal dust detection sensor group 02 and a dust removal experimental assembly 03, characterized in that,

[0033] The protective seat cover 00 is formed as a roadway structure with a roadway cavity inside, and extends along the extension direction of the roadway cavity to the roadway;

[0034] The dust removal experiment assembly 03 is located in the roadway cavity of the protective seat cover 00;

[0035] The dust removal experiment assembly 03 includes a coal dust generation assembly and a wet dust removal assembly, and the wet dust removal assembly is arranged above the coal dust generation assembly; and the height of the wet dust removal assembly is adjustable;

[0036] The wet dust removal assembly includes a top dust removal spray assembly and a side dust removal spray assembly, the side dust removal spra...

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...
