Installation of Kobulbaev E. for delivery of microparticles with subsequent ionization and combined aerodynamic-electrostatic collimation of particles, improved version 3 with preliminary calculations.

I present a stationary, ground-based, mine complex for delivery of mineral microparticles (CaCO₃ sized 0.5-0.7 μm) into the upper layers of the atmosphere. Structurally the installation is a vertical shaft (channel) of variable cross-section from 10 meters at the base and up to 1.6-1.8 meters in the upper part with a length of 200 meters, constructed in a rock massif by the method of driving from the surface of a high-mountain plateau (absolute elevation 5000–5500 m above sea level) vertically downward.the shaft (channel) is a three-layer load-bearing structure, the upper part of which transitions into a Laval nozzle (convergent-divergent contour). The working body carrier is nitrogen gas N₂ heated to 200 °C, supplied by compressor stations with stagnation pressure (total pressure) of 10-12 atm abs. in the lower part of the shaft (channel). The gas supply system consists of two circuits. The first, which is the main one, is located in the lower part of the shaft (at the bottom of the channel). The main gas circuit through which is supplied (80–90 % of nitrogen N₂ of the total volume): the gas is supplied through an annular collector built along the perimeter of the shaft at its base, equipped with nozzles. The second circuit is located in the upper narrowest part of the shaft (channel), at the place of transition of the shaft into the Laval nozzle this is the central gas circuit with a productive injector: through which the supply of the formed gas-dust mixture (nitrogen N₂ + microparticles CaCO₃) is carried out the temperature of nitrogen here is higher and reaches 200 °C the supply of the gas-dust mixture is carried out directly into the central part of the flow along the axis of the shaft (channel). Preliminary heating of nitrogen N₂ in both circuits is carried out by electric flow heaters. In the central circuit the temperature of nitrogen N₂ is also 200°C in order to evaporate the capillary moisture in the CaCO₃ particles, which in turn will reduce the adhesion factor of the particles.
