Embodiment Construction

[0021] The present invention measures the actual flare flow discharge data by monitoring the flame size in the flare discharge system, such as figure 1 , the present invention obtains the flame video of the torch discharge system through the network hard disk video recorder, transmits it to the rear graphics workstation for processing through the network, and stores the processed data in the database server, and sends the data to the remote user through the WEB server. Include the following steps:

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

[0023] 2), the graphics workstation processes each frame of image of the collected video, including image preprocessing and flame target feature point extraction; after the flame target feature point is extracted, the irregular figure surrounded by the feature points is calculated by the method of histogram I...

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 identification and flame flow measurement, and is a method for real-time measuring the torch flow of the torch discharge system based on the torch video. Background technique [0002] The purpose of the flare exhaust system is primarily to combust off-gases from the process, diverting organic hydrocarbons into water vapor and carbon dioxide. As far as exhaust gas is concerned, the flare discharge system is considered as the "sewer" of the factory, and the exhaust gas pipelines of various process units are collected to form a larger pipeline, and finally enter the main flare pipeline. The large size of the main flare line is required to transport large volumes of gas if an emergency in an individual process unit requires "dumping" all of the gaseous products from the individual units to the flare exhaust system. [0003] The measurement of flare flow has always been the demand of...
