Embodiment Construction

[0024] The inventive device such as figure 1 As shown, the entire constant electromagnetic field confined plasma arc generator includes a cathode head 1, a plasma torch 2, an anode head 3, a transfer arc 4, an electromagnet 5, an air inlet 6, an anode nozzle 7 and a liquid nitrogen cooling circulation system nozzle.

[0025] The working principle of the plasma generator is to use the transfer arc 4 as a heat source to obtain a high-energy-density plasma arc. The anode nozzle 7 and the cathode plasma torch 2 are respectively connected to the positive and negative electrodes. During operation, the gas passes through the plasma torch 6, and the gas is compressed by the effect of compression. Ionization generates plasma, and the generated plasma moves forward in the plasma torch 6 into the magnetic field generated by the electromagnet 5. Due to the constant electromagnetic field generated by the electromagnet 5, the plasma is constrained to move and converge to the circular electro...

Abstract

The invention discloses a constant electromagnetic field confinement plasma arc generating device which generates plasmas through the action of a cathode and an anode, the plasmas generate regular movement in a generator due to the action of a constant circular magnetic field, and the plasmas are compressed to form plasma beams. And the formed plasma beam is further cooled and compressed into a super-energy plasma beam at the anode nozzle, and finally the super-energy plasma beam is ejected. Plasma beams generated by the device are compressed twice, so that the plasma beams have large energy, the efficiency is improved, the plasma is prevented from continuously impacting the inner wall of the generator under the condition of constant electromagnetic field constraint, and the service life of the generator is prolonged.

Description

technical field [0001] The invention relates to the field of plasma generating devices, and specifically designs a plasma arc generating device constrained by a constant electromagnetic field. Background technique [0002] So-called plasma, it refers to a kind of uncharged ionized matter that has ions, electrons and core particles. Plasma includes: almost equal number of free electrons and anodic electrons. In a plasma, the particles in it have been ionized from the core particles. Therefore, when a plasma contains a large number of ions and electrons, it is the best conductor of electricity, and it is affected by the magnetic field, when the temperature is high, the electrons will be separated from the core particles. [0003] Plasma arc is to use plasma generating device to compress the free arc between cathode (such as tungsten electrode) and anode into an arc with high temperature, high degree of ionization and high energy density. Plasma arc is currently widely used ...
