Abstract:
1. A triple-flow vortex tube comprising: a body characterized by its axis, an inlet duct equipped with a device for methanol introduction, outlet ducts for the cold and hot gases, a liquid discharge duct, and a power separator; a vortex generator in the form of an Archimedean spiral located in a body at the inlet duct; the body comprising a separator having a streamlined end and a diaphragm having an conical inner surface, the separator and the diaphragm forming an annular channel, a surface of the streamlined end of the separator comprising the flutes numbering from 2 to 0.2 D, where D is a diameter of the power separator in mm; a flute depth is 0.05 D-0.1 D; a flute width c=0.05 D-0.2 D; a radius of a curvature of the flute r=3 D-3.5 D, and an angle of deflection of the flute a=30-75°; the separator being mounted so as to be capable of moving along the axis of the body, the separator being pressed against the diaphragm by a spring with a force G, defined by a formula where ρ is a gas flow density; v is the gas flow speed; S is an area of the streamlined end of the separator; Cosf is a cosine of a gas flow incidence angle; the inner portion of the body and the outer portion of the separator define a liquid chamber; and a vortex reducer having a cross-like shape and being located at an end of the power separator opposite to the body and mounted at a distance of at least 5 and no greater than 12 power separator diameters D to the body end, wherein the end faces of the vortex reducer have protrusions on each edge, a height L of each protrusion being selected from a range of 1 H to 1.5 H, wherein H is a thickness of a material of the vortex reducer.
