Development of a multifunctional installation of fine dispersed irrigation

Abstract

The intensification of the processes of mining and processing of mineral raw materials, characteristic of the modern development of mining production, is associated with significant dust pollution of the atmospheric air. As an economical and mobile means of dust suppression, it is recommended to use the developed impulse fine-dispersed irrigation system "Ustimor". The principle of operation of the installation is based on the pulsed displacement of water from the water-air tank by the combustion products of the fuel-air mixture under high pressure (>5 MPa). Experimental and industrial tests of the installation were carried out at the tailings storage facility of PJSC "Ingulets Mining and Processing Plant". The range of the installation is on average 120-130 m. The area of the irrigated surface in one cycle of operation is from 500 m2 to 750 m2. Fine spraying was observed along the entire length of the jet flight. In one hour of operation, the installation can release from 5 to 30 tons of water into the atmosphere in the form of drizzle. The intensity of watering for one work cycle is on average 0.85 l/m2. The possibility of autonomous operation of the installation and its remote control through the SCADA system has been confirmed. The installation of pulse fine-dispersed irrigation is recommended for use as a means of spraying liquid by the method of fine-dispersed irrigation on open areas of surfaces where dust is intensively swept and suspended. It can be used for dust suppression and humidification at tailings storage facilities, warehouses of bulk materials, landfills, technological highways. The "Ustimor" installation can also be used for fine-dispersed irrigation of plantations, vineyards, gardens, etc. Irrigation of leaf cover and soil surface will lower their temperature by 7 - 10 °C in the sun and by 6 - 6.6 °C in the shade.
