Portable oxyhydrogen flame igniting gun for test of combustion performance of micro-sample

Abstract

The invention relates to a portable oxyhydrogen flame igniting gun for tests of combustion performance of a micro-sample. The portable oxyhydrogen flame igniting gun comprises a gun body, a gas generation assembly, a gas spray pipe assembly and a control assembly, wherein the gun body comprises a handle and a barrel, insides of which are communicated; the gas generation assembly comprises an electrolyte cavity (11), electrodes (17) arranged in the electrolyte cavity (11) and a power unit (23) connected with the electrodes (17), and the electrolyte cavity (11) is formed in the handle; the gas spray pipe assembly comprises a gas spray port (1) and an igniting electrode (12); the control assembly comprises a trigger (15) arranged on the gun body, a trigger reset unit (16), a control circuit (8), a delayed igniting unit (14) and a gas valve (6) for controlling connection and disconnection of the barrel and the electrolyte cavity (11), and the delayed igniting unit (14) is connected with the igniting electrode (12). Compared with the prior art, the portable oxyhydrogen flame igniting gun is safe, small in size, light in weight and convenient to carry and test on site.

Description

technical field [0001] The invention belongs to the technical field of hazardous chemical detection, in particular to a portable hydrogen-oxygen flame ignition gun for testing the combustion performance of trace samples. Background technique [0002] At present, with the continuous development of social economy, my country has independently produced more than 45,000 kinds of various chemicals, forming an annual output value of more than 8 trillion yuan, and the output of some major products has ranked among the top in the world. With the rapid development of my country's chemical industry, the hazards caused by various chemicals to human health, safety and the environment have become increasingly prominent. Especially in recent years, my country's chemical accidents are on the rise. There are more than 2,000 accidents caused by chemicals every year, and the death toll exceeds 3,000. In addition, with the improvement of my country's economic strength and international influe...
