Problems solved by technology

Although this invention can also generate large-area plasma, it is not easy to generate uniform plasma because of the parallel array coaxial discharge structure and only enters the air from one end, and at the same time, it is difficult to effectively control the plasma temperature.

Abstract

The invention relates to a cold plasma generator for mutation breeding, which comprises an upper cover plate, a radio frequency electrode, a lower cover plate and a ground electrode, and is characterized in that the radio frequency electrode is connected with a radio frequency power supply; the ground electrode is connected with a radio frequency power ground wire; the upper cover plate covers theradio frequency electrode and forms an air chamber with the radio frequency electrode; the air inlet channel is arranged on the upper cover plate; the radio frequency electrode is provided with protruding parallel battens; the ground electrode is provided with narrow grooves matched with the battens of the radio frequency electrode; the parallel battens of the radio frequency electrode can penetrate through the narrow grooves of the lower partition plate and are inserted between the narrow grooves of the ground electrode in parallel. A plasma discharge chamber is formed between the parallel battens of the radio frequency electrode and the narrow groove of the ground electrode, and cooling circulation channels are arranged in the radio frequency electrode and the ground electrode, so thatlong-time plasma with stable temperature is generated in the biological mutation breeding process, especially in the animal and plant mutation process. Thus, the uniformity of the generated plasma iseffectively improved, and the temperature of the plasma is stable and controllable.

Description

technical field [0001] The invention belongs to the field of plasma technology, in particular to a cold plasma generator for mutation breeding. Background technique [0002] Plasma is the fourth state of matter distinct from solids, liquids and gases. Different excitation methods and generator structures can generate plasmas in different thermodynamic states. In recent years, the application of atmospheric pressure non-equilibrium plasma technology in various fields has attracted more and more attention due to the removal of complex and expensive vacuum systems. Atmospheric pressure non-equilibrium plasma can be generated by using plasma generators with different electrode structures (such as dielectric barrier structure, needle-plate structure, exposed electrode structure, etc.) and power sources with different frequencies (microwave, radio frequency, pulse, and direct current, etc.). Atmospheric pressure non-equilibrium plasma generation methods commonly used in the fiel...
