METHOD AND A DEVICE FOR PRODUCTION OF PLASMA

摘要

The invention relates to a method and device for production of plasma and finds its application in heat engineering, for destruction of any kind of waste, for gasification of carbon- containing solid and liquid materials, for melting and soldering of metal and non-metal materials. In this method for plasma production, water is supplied under pressure from a water tank (1) by a water pump (8) to a distributor (2), wherefrom the water is divided into two water streams, both of which pass through flexible pipe connections (3) and each one separately goes into a pair of pipes with one of their ends open (5), with each of the pipes accommodating one electrode (4), where under the influence of high voltage direct current applied in the clearance between the two flowing-out water streams plasma (6) is produced with temperature exceeding 4000 °C, while the unused part of the water, flowing freely throughout the open ends of the pipes (5) via the funnel-like collector goes back to the water tank (1). The plasma producing device comprises at least one pair of pipes (5), made of heat- resistant insulation material, in which water is supplied from a water tank (1), by a water pump (8) installed on it, feeding pressurized water to distributor (2), and by means of flexible pipe connections (3) the water is supplied to the pipes (5), inside which at least one pair of electrodes (4) are installed, each pipe accommodating one of them, connected to the opposite poles of high voltage direct current (7) source.
