Method for determining explosion limit of multicomponent mixed gas

Abstract

The invention relates to a method for determining explosion limit of multicomponent mixed gas. The conventional physical and chemical parameters and the mixture ratio of pure gas are adopted to build corresponding explosion limit prediction models aiming at different classes of multicomponent mixed gas, and the built models are utilized to predict the explosion limit of unknown mixed gas. The method comprises the following steps of: 1, collection of modeling samples of the multicomponent mixed gas and the explosion limit data of the multicomponent mixed gas; 2, classified processing of the modeling samples of the multicomponent mixed gas; 3, determination of the physical and chemical parameters and collection of the data; 4, building of the prediction models; 5, confirmation and correction of the models; 6, and application of the prediction models. The explosion limit is an important indicator for measuring the explosion risk of the mixed gas, and a predicting method for researching the explosion limit of the multicomponent mixed gas has importance for the prediction and monitor of the gas explosion. The method is sample and has high prediction accuracy, and the invention provides a simple, fast, accurate and reliable predicting method for predicting the explosion limit of the multicomponent mixed gas.

Description

[0001] technical field [0002] The present invention relates to a method for the explosion limit of multi-component mixed gas, especially a method for determining the explosion limit of unknown multi-component mixed gas through existing manuals, databases or data of conventional physical and chemical parameters of a single gas detected, specifically A method for determining the explosion limit of multi-element mixed gas by using physical and chemical parameters and component distribution ratio. Background technique [0003] With the continuous development of the chemical industry and the diversification of chemical products, various chemical products have been widely used in various sectors of the national economy. At present, more than 30 million chemical substances have been discovered and synthesized, among which there are more than 80,000 chemical products used by human beings daily, and this number is increasing at a rate of nearly 1,000 each year. Among the many chem...

Problems solved by technology

[0008] The purpose of the present invention is to mainly rely on experiments and predictions to obtain the explosion limit of multi-component mixed gases at present, while the experimental method has the disadvantages of high cost, long cycle and high risk, and the existing prediction methods are cumbersome to use and poor in accuracy. In order to solve problems such as narrow scope of application, invent a method with good prediction effect, wide application scope, and conventional physical and chemical parameters (obtained through routine experiments or consulting manuals and databases) and proportions of a single gas component to achieve the explosion limit of multiple gas mixtures. method of prediction
