Continuous chemical reaction method and detonation reactor using continuous chemical reaction method

Abstract

The invention discloses a continuous chemical reaction method using gas counter-current detonation waves and a detonation reactor using the continuous chemical reaction method. The continuous chemical reaction method comprises: combustible gas reactants are continuously injected into the detonation reactor; chemical reactants which need a high temperature for reactions and destruction are continuously injected into the detonation reactor; air / oxidants / assistants are continuously injected into the detonation reactor; mixing of the combustible gas reactants, the chemical reactants and the air / oxidants / assistants is promoted by a detonation promoter; a mixed gas is ignited by an ignition device which is arranged at the downstream end of the detonation promoter; counter-current detonation is occurred by tempering of the combustible mixed gas through use of the detonation promoter; when the detonation waves arrive a feed end of the detonation reactor, flame extinguishing is occurred through use of the detonation waves; and then the procedure of mixing, ignition, counter-current detonation, and flame extinguishing of the combustible gas reactants and the chemical reactants is continuously repeated, so that the chemical reactants can carry out the reactions or be destroyed through high temperature and high pressure of the detonation waves.

Description

technical field [0001] The present invention is a method capable of continuously generating gas countercurrent detonation shock wave (Detonation Wave) and using the high temperature and high pressure characteristics of detonation shock wave to continuously carry out chemical reaction and a detonation reactor using the method, which can be effectively applied to the semiconductor industry Perfluorinated PFCs waste gas treatment, VOC waste gas treatment, high temperature gasification of oil or organic solids. Background technique [0002] Detonation refers to the gas mixture of flammable gas and an appropriate amount of air or oxygen, which exists in a tubular container. When the gas mixture is ignited at a certain point in the tube, the flame surface will proceed very quickly, which is called deflagration (Deflagration), and Combining with the compression wave in front of its progress direction to generate a shock wave, it will suddenly increase the combustion propagation spe...

Problems solved by technology

The propagation of the traditional combustion process is easily affected by external conditions, especially the environmental pressure; however, the transmission speed of the detonation shock wave is extremely fast, and is almost not affected by external conditions, and its detonation velocity is a constant under certain conditions. the constant
