Distributed spectrum temperature measuring device for cloud and mist explosion field

Abstract

The invention relates to a distributed spectrum temperature measuring device for a cloud and mist explosion field, which belongs to the technical field of detection of signals. The device consists of one or more than one light path sensing part, one or more than one steel pipe bracket, one or more than one photoelectric conversion and storage part and an upper computer data processing system. In the device, a light path sensing system is used for combining a storage and measurement technology, so that a temperature in a cloud and mist explosion area can be detected in a near field; the light path sensing part has a small volume, and can be placed in a cloud and mist area according to requirements to finish multipoint measurement and fit temperature distribution conditions in the cloud and mist area; and the storage and measurement technology is utilized, so that data is processed after the measurement, and can be processed by flexibly selecting various data processing methods according to one, two or more on-site light path detector configuration modes.

Description

technical field [0001] The invention relates to a distributed spectrum temperature measuring device used in cloud and fog explosion fields, and belongs to the technical field of signal detection. Background technique [0002] With the development of modern industry, industrial explosion accidents happen from time to time. M&MPC (Marsh&Mclennan Protection Conclusion) statistical analysis of 150 industrial disasters in 1989 showed that industrial explosion disasters accounted for about 60% of the total industrial disasters and were one of the most important industrial disasters. Among all kinds of industrial explosion accidents, a considerable part is caused by the explosion of flammable substances suspended in the air. For example, in the process of coal mining, after gas, coal dust and air are mixed and reach a certain concentration, explosion accidents can occur when encountering unexpected energy such as sparks; in petroleum and chemical production, the leaked combustible...

Problems solved by technology

However, these methods have a common feature, that is, on the one hand, due to the complex optical system and precise coordination, strong vibration in the explosion field will cause the optical system to be disordered, making it impossible to test

On the other hand, the shock resistance of optical devices is relatively poor, and some optical devices are fragile

Therefore, these precision instruments can only detect the entire cloud explosion area far away from the cloud explosion area, and can only test the surface temperature of the cloud explosion area, but cannot obtain the detonation center temperature and the distribution of its temperature gradient; although the infrared detection method It can display its general temperature gradient, but due to the large number of opaque substances and smoke in cloud explosions, its test accuracy is seriously affected
