Abstract

The invention discloses a plasma fire extinguishing apparatus, which consists of a shell and an internal circuit, wherein the internal circuit comprises a sensor, a central processing and analyzing circuit, a voltage control circuit, an external control circuit and a plasma generator; the sensor detects environmental conditions comprising temperature, air pressure and wind power and transmits data to the central processing analysis circuit; the central processing and analyzing circuit processes and analyzes the data, and sends an instruction; the voltage control circuit receive the instruction and adjusts the voltage of the plasma generator, or an operator adjusts the voltage of the plasma generator according to personal judgment; the plasma generator performs preionization on gas by a radio frequency preionization method, and performs discharge breakdown on the gas subjected to preionization by a method of stopping discharge through a medium to form plasma airflow so as to act on flames, so that the fire is safely, cleanly and efficiently extinguished; meanwhile, an aim of flexibly controlling the plasma generator to generate proper plasma airflow to improve the fire extinguishing efficiency is fulfilled.

Description

technical field [0001] The invention belongs to the application of plasma technology, and in particular relates to a fire extinguishing method using a plasma discharge method of dielectric barrier discharge (APDBD) under atmospheric pressure. Background technique [0002] Existing fire extinguishing methods mainly include cooling fire extinguishing, suffocation fire extinguishing, isolation fire extinguishing and chemical suppression fire extinguishing, and these methods all stop the combustion reaction by destroying the conditions of combustion. However, there are some defects in these methods: the fire extinguishing agent destroys the fire object, pollutes the environment, needs to be replaced regularly so that resources are wasted, damages the operator, and the number of times and scope of use are limited. A flame is a plasma, and during combustion, high-energy particles in the flame collide with each other, causing ionization of the gas, which is often called thermal ion...
