A coke oven raw gas rising pipe working state monitoring system

Abstract

The invention discloses a coke oven raw gas rising pipe working state monitoring system, which belongs to the technical field of temperature monitoring. The invention includes a laser rangefinder and an infrared thermometer respectively installed on the focus pusher, and a man-machine control interface connected with the laser rangefinder and the infrared thermometer respectively to realize information transmission, and the temperature measurement of the infrared thermometer The direction is toward the rising tube, and the ranging direction of the laser rangefinder is parallel to the moving direction of the focus pusher. In the present invention, the coke pusher that operates uninterruptedly throughout the day in the coke oven system is used to monitor each rising pipe, and an infrared non-contact temperature measuring sensor is used to scan and monitor the temperature of each rising pipe, and a laser distance measuring sensor is also used Scanning the position of each riser finally achieves the purpose of low-cost and high-efficiency real-time monitoring of the working status of the riser, providing technical support for timely replacement of damaged risers, and preventing problems before they happen.

Description

technical field [0001] The present invention relates to a monitoring system, more specifically, to a working state monitoring system of coke oven raw gas rising pipes, which mainly uses the detection of the working temperature of the rising pipes to judge the working state of each rising pipe. Background technique [0002] The rising pipe is an auxiliary equipment of the coke oven installed on the top of the coke oven to lead out the raw gas in the carbonization chamber. The rising pipe is generally composed of a cylinder body, a bridge pipe and a flap seat (also known as a water seal valve body). The riser tube body is a cast iron or steel plate welded cylinder, lined with clay bricks; some are also made with a jacket or a spiral tubular structure, and water or an organic heat carrier is passed through the jacket or spiral tube. To recover the sensible heat of raw gas. [0003] In a coke oven system, many risers need to be installed, and because the working environment of...

Problems solved by technology

[0006] The purpose of the present invention is to overcome the problem of difficulty in monitoring the failure of the existing coke oven raw gas riser pipe, and to provide a working state monitoring system for the coke oven waste gas riser pipe. By adopting the technical scheme of the present invention, the uninterrupted The running coke pusher monitors each rising tube, and uses an infrared non-contact temperature sensor to scan and monitor the temperature of each rising tube, and uses a laser ranging sensor to scan the position of each rising tube, and finally Realize the purpose of low-cost and high-efficiency real-time monitoring of the working status of the riser, provide technical support for timely replacement of damaged risers, and prevent problems before they happen
