Tubular concentrator for concentric radiation of electromagnetic waves

Abstract

The invention relates to an electric machine (fixed, mobile or portable) suitable to the physical, dynamic, continuous conditioning of materials having the ability to absorb electromagnetic radiation, which have the need to be treated through the irradiation of UV or IR, even without entering into contact with the machine and this also through the vacuum. The invention mainly uses the Lambert and Stefan-Boltzmann postulates, or rather the physical assumptions of the transmission of energy by radiation and in particular the concentration and the emission proximity of energy between transmitter and receiver (which varies with the square of the distance) and the emission intensity (which varies with the fourth power of the temperature). The extremely small distances between transmitter and receiver of electromagnetic energy and the cylindrical shape and concentric electromagnetic emission source (reflected from the outside towards the centre) are the main essence and novelty of the invention. The electric machine, the section of which is represented in the attached drawing of which are hereby provided in the description the letters as a reference, is composed of a suitable current generator that feeds an emitter of electromagnetic waves (EMW) represented by a coiled heating wire (heater function) or by a strip of LEDs (germicidal function) (E), which envelops a fused quartz tube (or a substitute material) of suitable thickness (D), which in turn can contain an internal (or more) further tube (C) of the same or similar transparent material of the first, adapted to the passage of materials to be treated (A); the tube (D) wrapped with the spiral emitter (E) is in turn encased by a tube (F) in suitably appropriate material to shield electromagnetic emissions towards the outside. Such screening tube will (eventually) in turn be inserted in a relatively thick insulating cup (G), coated in turn with reflecting material (H), to further isolate and insulate the system as much as possible from the external environment.
