Description

ROOM-EVAPORATOR WITH MAGNETIC HEATING

Field of the Invention

This patent has application in many areas of industry. There are current uses for it in chemical heating, desalination, biodiesel synthesis and environmental cleaning industries. Hot water from the rotoevaporator can be used to heat homes, hospitals, and villages in cold, remote locations. It can also provide hot water for agriculture in cold weather.

Background

Roto-Evaporator is a metal cylinder, usually made of stainless steel, with holes in its surface that rotates immersed in water, which causes water to heat up due to friction forces between the rotor and water, generating heated steam under high pressure. . Anomalous heat production was detected in this device created by James L. Griggs in 1987 (US Patent No. 5,188,090) which he calls the hydrosonic pump and later perfected (US Patent No. 0701174-1). The explanation of anomalous heat is a joint effect involving frictional and cavitation forces, the latter consisting of the rapid expansion and collapse of air bubbles resonating with the ultrasonic waves generated by the cavities on the rapidly rotating rotor surface. The heat produced by ultrasound is responsible for the evaporation of water within commercial nebulizers that use ultrasound of a small piezoelectric crystal to generate expansion and collapse of naturally occurring air bubbles in water. Nevertheless, commercial rotoevaporators generate little water vapor per unit of time due to the low heating power of the cavitation and hydrodynamic friction they develop during rotor rotation. This represents low process throughput and limited industrial applicability.

goal

The purpose of the Magnetic Heating Evaporator Roto Evaporator is to build a rotoevaporator that produces more steam and heat per unit of time by heating the magnetic induction field generated by permanent magnets or electromagnets (coils) on the rotor. metallic.

Solution

The Magnetic Heating Evaporator Evaporator features a metallic rotor of copper, aluminum, brass, stainless steel, galvanized steel, zinc, tungsten containing cavities in its surface that rotates inside a cast iron or galvanized steel (stator) cylinder thus producing higher amount of steam and heat per unit of time due to heating caused by magnetic induction from magnets or copper wire coils on the rotor during its rotation. Any metal when rotating or linearly moving near a magnet heats up due to induction of eddy currents Id 3/4

caused by the magnetic field of the magnet. It is a process that occurs in hydroelectric plants where copper wires rotate near permanent magnets generating electric current (parasite). And we know that an electric current can generate Joule heat that, for example, heats an electric oven or iron. In the rotoevaporator the magnets generate electrical currents on the surface of the metal rotor which in turn will simultaneously heat the surface of the same by Joule effect in a similar way as described above.
