Problems of protection of urban ambient air pollution from industrial dust emissions

“…Of all the existing diversity precipitators modifications in this respect are different devices with counter swirling flow (CSF), the benefits of which are found in the works of many researchers [12][13][14][15][16][17], and emission dedusting system CSF effectively exploited in various enterprises [15][16][17][18][19][20][21].

“…Fig. 2 shows one embodiment of a system of purification of industrial emissions of dust, composed of a series arrangement of two devices CSF suction hopper of the dust collector and returning the second stage recycle stream to the lower input apparatus CSF first stage [16].…”

Justification of the calculation methods of the main parameters of vortex chambers

“…The above relations are based on an analysis of the results of the studies [10][11][12], in which the models of swirling dispersed circular flows in a smooth cylindrical tube with a swirler are considered, nu merical study of models, experiments of mixing oppositely swirled flows and others are experimentally investigated.…”

“…For calculations it is possible to take both the conditional velocity of the main gas flow in the working part of the chamber, while, as shown by practical studies [8,12] 7≤ W 0 <15 m/s, and W 0 is determined by the relation:…”

Study of functioning of a vortex tube with a two-phase flow

“…Hence, it is advisable to consider such an option that when a dusty gas stream is fed into the main unit like a setting forebunker for dry scrubbing, preparation of the gas before its coming to the forebunker could be carried out in vortex tubes with a partial recirculation of the heated gas due to the Ranque effect. Principal provisions of such an approach were discussed in [15][16][17] where it was noted that implementation of the 'vortex tube -setting forebunker' scheme can ensure fine cleaning of the incoming gas from impurities and utilization of the purified gas energy. However, there are no experimental data that would confirm the above conclusion for specific industrial conditions [15][16][17].…”
