(Summary description)Atmospheric plasma cleaning machine working gas discharge is divided into DC discharge, low frequency discharge, high frequency discharge, microwave discharge and other types. Different working gas discharge principle of atmospheric plasma cleaning machine has different functions and applications. Atmospheric plasma cleaning machine usually under the action of electric field gas is broken down and conductive physical phenomenon known as gas discharge. The ionized gas thus produced is called a gas discharge plasma. Atmospheric plasma cleaning machine according to the frequency of the electric field added, gas discharge can be divided into DC discharge, low frequency discharge, high frequency discharge, microwave discharge and other types. Direct current (DC) discharge because of its simple and easy, especially for industrial atmospheric plasma cleaning machine device can apply a lot of power is still used. The range of low-frequency discharge is generally 1-100khz, and now the frequency commonly used in the device is 40kHz. At present, the most commonly used atmospheric plasma cleaning machine in experimental equipment and process equipment is the high frequency discharge device, whose frequency range is 10 ~ 100MHz. As it belongs to the Radio frequency spectrum range, it is also known as Radio frequencydischarge (RF discharge), with the commonly used frequency of 13.56mhz. When the electric field frequency of the atmospheric plasma cleaning machine exceeds 1GHz, it belongs to Microwave discharge (MW discharge). The commonly used microwave discharge frequency is 2.45GHz.
