Functional Characteristics Of Dust Removal Equipment
The foam acts on the dust through good coverage, wetting, adhesion, etc., effectively reducing the dust concentration on the mining face, greatly improving the working environment of the mining face, improving the work efficiency of the underground operators, and effectively reducing the pneumoconiosis of the front-line workers. incidence of disease.
Compared with other wet dust suppression methods, foam dust suppression can reduce the water consumption by 50% to 80%, and the dust suppression efficiency is 3 to 5 times higher than that of spray water. Foam dust suppression has the following characteristics:
1. The foam can cover the dust source without gaps, and fundamentally prevent the dust from spreading out;
2. After the liquid forms foam, the total volume and total surface area are greatly increased, which increases the collision efficiency with dust and purifies the working environment of the underground mining face;
3. The liquid film of the foam contains special additives, which can quickly change the wetting performance of the dust and increase the speed of the dust being wetted;
4. The foam has good viscosity, and the dust will be quickly adhered by the foam after contact with the foam.
5. Suppress the sparks generated by the action of the roadheader's pick and coal and rock, and prevent the resulting gas and coal dust explosion accidents.
6. The water consumption is small, avoiding the subsidence of the fully mechanized excavator caused by the large water consumption of water mist dust removal, and improving the work efficiency.
7. The dust removal efficiency is high, which greatly improves the line of sight of the roadheader driver, eliminates the safety hazards brought by it, and improves the section quality and production efficiency.
