Abstract

The invention discloses a multi-spark high-energy electrostatic generating device and a control method thereof. The multi-spark high-energy electrostatic generating device includes a high-energy electrostatic generating device, a high-voltage electrode, a ground electrode, a bracket, and a flange plate. The high-energy electrostatic generating device includes a high-voltage power supply, Charging relay and several charging and discharging circuits, each charging and discharging circuit is independent of each other, can generate adjustable energy electrostatic sparks between each pair of high voltage electrodes and ground electrodes. By changing the number of charging and discharging circuits, the number of static sparks generated at the same time can be changed. Through this method, multiple ignition sources can be generated at the same time to ignite the dust cloud to be tested together, which improves the ignition efficiency; each charging and discharging circuit can generate spark energy up to 50 J and the discharge time is less than 1ms, which improves the efficiency of traditional batteries. Igniter spark energy and reduced discharge duration. The multi-spark high-energy electrostatic generation method can be used as a substitute for the chemical ignition method to achieve safer, more convenient and more accurate measurement of dust explosion characteristic parameters.

Description

technical field [0001] The invention belongs to the technical field of electronic igniters, and in particular relates to a multi-spark high-energy electrostatic generating device and a control method. Background technique [0002] Flammability, explosion index, lower explosion limit and limiting oxygen concentration are important parameters to evaluate the risk of dust explosion. In the fields of food, mining, chemicals, textiles, etc., the production, processing and transportation of combustible dust are mostly involved, which increases the potential danger of combustible dust explosion. The measurement of the combustion and explosion characteristic parameters of combustible dust can provide an important reference for the explosion-proof and explosion-venting design of combustible dust. [0003] The measurement of dust explosion characteristic parameters is to uniformly disperse the dust to be tested into the test device through a certain pressure to form a dust cloud, and...

AI Technical Summary

Problems solved by technology

[0004] Current 20L spherical explosion parameter tester, 1m 3 Spherical explosion parameter testers and other dust combustion and explosion characteristic parameter testing instruments still generally use chemical ignition methods, but they are faced with the difficulty of obtaining chemical igniters, while electrostatic ignition methods are difficult to obtain industry approval due to large measurement errors

This has caused the dust explosion detection industry to face the dilemma that although there are measuring instruments, there is no ignition device.
