Problems solved by technology
It is also realized by installing a displacement sensor on the opening and closing cylinder of the rising pipe cover, but due to the very high temperature of this part and the influence of vibration during the opening and closing process, it is difficult for electronic components to operate reliably, which restricts the realization of unmanned coal loading vehicles

Embodiment Construction
[0036] The method for detecting the state of the coke oven riser of the present invention will be further described below.
[0037] A detection method for the state of the riser of the coke oven, comprising the following steps:
[0038] (1) Install the temperature detection device at a position that can scan the riser and away from the riser, and detect the temperature of each part of the riser;
[0039] The temperature detection device is installed on the coal loading car to scan a part of the riser pipe, such as the riser pipe cover or straight pipe section; Only the ascending pipe is used to detect the temperature of each part of the ascending pipe;
[0040]The temperature detection device is an infrared thermometer or an infrared thermal imager, and the infrared image is obtained by point scanning, flat scanning or thermal imaging, and the temperature data is calculated; heat insulation facilities, ventilation facilities and / or or rainproof facilities;
[0041] (2) Moni...

The invention provides a method for detecting the state of a riser tube of a coke oven. The method comprises the steps: mounting a temperature detecting device at a position far away from the riser tube and detecting the temperature of various portions of the riser tube; detecting the temperature of a cover region of the riser tube of the coke oven by the temperature detecting device, and transmitting detection data to a control device before coal is loaded into the coke oven; in the running process of the coke oven, detecting the temperature of a shell of a straight tube section of the risertube by the temperature detecting device, and transmitting detection data to the control device. The riser tube can be scanned at the position far away from the riser tube. By the method, the workingstate of the straight tube section of the riser tube can be monitored in real time, problems can be discovered for the first time, explosion of the riser tube and irreversible damage to an oven body of the coke oven are avoided, and the method is an important supporting technical means for safety production of the coke oven, and particularly is an indispensable matched guarantee technical measurefor a waste heat recycling type riser tube system.
Description
technical field [0001] The invention belongs to coke oven automation technology, in particular to a method for detecting the state of a coke oven riser pipe. Background technique [0002] The rising pipe is the necessary channel for the export of high-temperature raw gas during the coking process of the coke oven. The cover of the rising pipe is closed during the coking process. The waste heat recovery riser with indirect heat exchange between the pipe section and water also has the traditional riser lined with refractory material. [0003] With the intensification of market competition and the increase of labor costs, the unmanned operation of coke oven coke pushing has become the main direction of the current coking industry. Among them, it is most difficult to realize unmanned coal loading vehicles. In addition, the coal loading operation is directly related to the state of the riser, and the automatic judgment of the state of the riser is a necessary condition for reali...
