overview
Dust removal equipment refers to devices that separate dust from flue gas, also known as dust collectors or dust removal devices. The dedusting equipment is to use the underground dedusting water pipe and air pressure pipe to add certain additives in the water, introduce air pressure, complete a series of technological processes through special equipment, generate foam, and spray it to the dust source through the distributor and sprinkler support components.
Functional Features
The foam acts on the dust through good covering, wetting, adhesion and other ways, effectively reducing the dust concentration on the mining face, greatly improving the working environment of the mining face, improving the working efficiency of underground operators, and effectively reducing the incidence rate of pneumoconiosis of mining front-line workers.
Compared with other wet dust suppression methods, the water consumption of foam dust suppression can be reduced by 50%~80%, and the dust suppression efficiency is 3~5 times higher than that of spray spraying. Foam dust suppression has the following characteristics:
1. The foam can cover the dust source without gaps, and fundamentally prevent the outward diffusion of dust;
2. After the liquid forms foam, the total volume and total surface area increase significantly, increasing the collision efficiency with dust, and purifying the working environment of the underground mining face;
3. The liquid film of foam contains special additives, which can rapidly change the wettability of dust and increase the speed of dust wetting;
4. Foam has good viscosity. Dust and foam will be quickly adhered to by foam after contacting.
5. Inhibit the sparks generated by the cutting teeth of the tunneling machine and the interaction between coal and rock, and prevent gas and coal dust explosion accidents caused by this.
6. The low water consumption avoids the sinking of the comprehensive excavator caused by the large water consumption of water mist dust removal, and improves work efficiency.
7. The high dust removal efficiency greatly improves the visibility of the excavator driver, eliminates the safety hazards caused by it, and enhances the quality of the cross-section and production efficiency.
