Problems solved by technology

It can be seen that most of the existing devices are unilaterally related to the flame characteristics or the charge-to-mass ratio of charged particles. There is no public report on the combination of the two, especially the experimental device for studying the interaction between charged droplets and flames.

Abstract

The invention discloses an experimental device for studying interaction of charged particles and flame. The charge-to-mass ratio variation of a single charged particle under the action of flame can be quantitatively measured, and a simple and feasible experimental method and device are provided for studying flame ionization characteristics and electrochemical atomization fire extinguishing mechanisms, with low cost and high precision. The experimental device comprises a charged particle generator, a front charge-to-mass ratio measuring channel, a model flame system with a central channel and a rear charge-to-mass ratio measuring channel from top to bottom in sequence, wherein charged particles generated from the charged particle generator freely drop to penetrate through a flame area above the flame generated from the mold flame system through the central channel; the charge-to-mass ratios before and after the charged particles penetrate through the flame area are respectively measured through the front charge-to-mass ratio measuring channel and the rear charge-to-mass ratio measuring channel, so that quantitative variation of the charge-to-mass ratio of the charged particles under the action of flame can be acquired.

Description

technical field [0001] The invention relates to an experimental device for studying the interaction between charged particles and flames, which is especially suitable for measuring the charge-to-mass ratio variation of charged liquid droplets passing through flames, and belongs to the technical field of combustion and fire extinguishing. Background technique [0002] Charged water mist has an important application prospect in the fire prevention of important places such as aviation, spaceflight, and ships. The interaction between charged droplets and flames involves many complex physical and chemical processes, such as the movement, deformation, evaporation, charge exchange, and chemical reactions of droplets in the flame zone. Clarifying the main mechanism and controlling factors of the interaction between charged droplets and flames is of great significance for understanding the fire extinguishing mechanism of charged water mist, improving the fire extinguishing effect of ...
