Embodiment Construction

[0021] The present invention measures the actual flare discharge data by monitoring the flame size in the flare discharge system, such as figure 1 In the present invention, the flame video of the torch discharge system is obtained through the network hard disk video recorder, and transmitted from the network to the rear graphics workstation for processing, the processed data is stored in the database server, and the data is sent to the remote user through the WEB server. It includes the following steps:

[0022] 1) Set up a network hard disk video recorder to collect the flame video of the torch discharge system, and transmit the collected video to the graphics workstation;

[0023] 2) The graphics workstation processes each frame of the captured video, including image preprocessing and extraction of characteristic points of the flame target; after the characteristic points of the flame target are extracted, the irregular graphics enclosed by the characteristic points are calculat...

Abstract

The invention relates to a method for real-time measurement of the torch flow rate of a torch discharge system based on torch videos. A dynamic image mode recognition technology is used, a high-definition camera is used for picking up the flame core of the torch, the pickup target is converted into image signals to be transmitted into a graphic work station, the flow rate of exhausted gas is judged and calculated according to the flame core shape size, and the practical torch flow rate discharge data is measured through monitoring the flame size in the torch discharge system. The method has the advantages that the problem that the torch discharge cannot be directly and effectively measured for many years is solved, the measurement precision can reach a value within 10 percent, a good supervisory effect is realized on the device discharge through the torch discharge history trend, and the unnecessary discharge is reduced; and the production process operation condition and the practical condition of the torch discharge are conveniently known, and extremely high reference effects are reached for stabilizing the production and improving the safe, stable, long, full and excellent operation of devices.

Description

Technical field [0001] The invention is used in a torch discharge system, relates to image flame recognition and flame flow measurement, and is a method for real-time measurement of the torch flow of the torch discharge system based on the torch video. Background technique [0002] The purpose of the flare exhaust system is mainly to burn waste gas from the process and forward organic hydrocarbons into water vapor and carbon dioxide. As far as waste gas is concerned, the flare discharge system is regarded as the "sewer" of the factory. The waste gas pipelines of various process units are gathered to form a larger pipeline, and finally enter the main flare line. If a single process unit has an emergency and needs to "dump" all gas products from each unit to the flare discharge system, then the large-sized main flare pipeline needs to transport a large amount of gas. [0003] The measurement of flare flow has always been the requirement of chemical, petrochemical, oil refining and o...
