Description
Technical Field
The invention relates to a dust coalescence device based on an atomized vortex fluid generation unit group, which belongs to the technical field of fluid application, in particular to a device which combines individual units generated by the atomized vortex fluid to form a multi-unit combined group by relying on the self-absorption capacity of the generated fluid under the action of marangoni force, and by means of the nonuniformity among the units, the combined group forms gradient difference among the surface tensions of fluids in different phases through the control and regulation of the solid-liquid-gas three-phase state alternating change in the flowing process, and in the process of close contact of the phases, a large amount of dust microparticles in the atomized fluid are gathered and separated to micro water drops to complete reliable coalescence and produce unexpected effect energy superposition to realize high-efficiency dust removal, wherein the device generates 'multi-phase flow atomized vortex fluid', the size direction and the penetration distance of the penetration angle of the group of fluid are adjusted by a physical device in the dust removal process, the state and the density of the gas atomization vortex group of fluid are changed through the change of gravity and speed, and a tiny water drop aggregation nucleus is generated along with the alternate change of solid, liquid and gas phases in the flowing process; the flow is hindered by the temperature and volume change, the surface tension gradient difference is formed among the surface tensions of fluids in different phases due to the asynchronous change of the fluids of the aerial atomization vortex group around a large number of tiny water drop cores, the frustration effect enables the aerial atomization vortex fluid around the tiny water drop cores to have enough space and time, and the fluids in different phases are in full contact, so that substances with low surface tension flow towards substance phases with high surface tension and gather in the tiny water drop cores under the action of Marangoni force, substances with low surface tension flow towards substance phases with high surface tension and gather under the action of the Marangoni force, and a large number of dust microparticles in the aerial atomization fluid gather towards the tiny water drop cores, namely primary coalescence of the dust microparticles is realized under the action of the Marangoni effect.
Background
The existing main treatment means for industrial dust pollution comprises the following steps:
the high-pressure atomization dust removal technology as a main dust removal means of an underground working face has the following defects: 1) along with the continuous increase of the working pressure of the fluid, water mist particles are crushed into tiny particles by pressure, so that the particles are dedusted by colliding with dust particles in the space, the pressure is increased to a certain extent, the capacity of capturing dust is improved, but the fluid detention time in the air is further reduced, so that the capacity of capturing dust with the diameter of 1-2.5 microns is still poor on the premise that the water consumption and the energy consumption are synchronously increased, and the requirement of green and efficient dedusting fluid cannot be met basically; 2) the technology for treating the rock stratum dust which is difficult to dissolve in water still has no qualitative improvement, and the problem that the rock roadway dust is difficult to treat still exists.
Secondly, the fan absorbs, filters and removes dust, and the dust removal efficiency is low, the energy consumption is high, and the limitation of the use condition is obvious.
Thirdly, electric dust removal and magnetic dust removal have high dust removal efficiency and extremely harsh use conditions, and cannot be used in a large area.
Adsorption dust removal and the like are not easy to be used in large-area industry. As in the patent: the coal mine dust removal ventilation device, application No. CN202110912870.6, adopts a sand board layer as a filter screen to filter air dust, greatly improves the air filtering effect and is beneficial to reducing the cost; a coal mining dust removal device capable of saving water resources, application number CN 202110891225.0; dust collection treatment can be performed while water is sprayed, so that the dust settling effect is further improved; it can be seen that the above technical means are still ineffective for respiratory dust and dust insoluble in water. The fog flow speed of the conical solid fog column sprayed by the nozzle is high, and dust collided by fog particles can generally fall down. However, because the fog flow velocity is high, the air injected around the fog flow velocity easily blows away the respiratory dust with small particle size, and the dust settling effect is objectively influenced. For example, the amount of high-pressure atomized water required by the existing underground coal mine tunneling working face is 3600kg/h, but even if the underground dust pollution is still a serious disaster area by adopting the non-green means, a new dust treatment technology is objectively needed to be brought out, so that the working flour dust treatment problem can be realized efficiently, environmentally and environmentally.
Semiconductors are generally composed of a lattice structure, and the process of growing a pure crystal (e.g., silicon) involves the purification of metals. This process starts with the melting of the solid metal and then during the purification, the marangoni effect causes convection in the liquid phase. Thus, impurities such as oxides (generally lighter than the metal) can be separated over time. Furthermore, the heat transfer must be adjusted to control the shape of the solidification front. The acting force generated by the marangoni effect can influence the crystal growth, so that faults occur in the structure, the faults can reduce the semiconductor performance of the material, the device has defects, and obviously, the marangoni effect can enable impurities lighter than metal to be gathered and separated out after a period of time.
In most cases the absorptive capacity for the dedusting fluid is extremely limited, so the applications and effects of the spray cell groups are limited, and the degradation of the capacity of the individual cells often occurs after the spray cell groups are combined. However, the fluid self-absorption capability and the capability of adapting to complex application occasions of the invention are strong, the multi-unit combination has the advantages that by means of the nonuniformity among the units, the fluid generated by the combination has diversity and can generate some new effects through the control and adjustment of gas, liquid and solid states, so the group effect characteristic is different from other dust removal mechanisms and application effects, the dust removal work is more convenient and simple, the good group effect can be generated, and the adverse effect on the working environment is avoided.
