A detection method for the clogging of coke oven coal charging port

Abstract

A detection method for the blockage of the coal charging port of the coke oven. The temperature measuring device is installed on the coal charging car. After the coal charging car removes the cover and before the coal charging sleeve is lowered, the temperature measuring device detects the temperature of the coal charging port area. , and transmit the data to the on-board PLC system of the coal loading vehicle; the temperature measuring device and the coal loading vehicle cover remover operate synchronously, after the coal loading vehicle cover removing machine removes the cover to the upper limit, the temperature measuring device extends out at the same time, and aligns with the carbonization chamber to add The temperature of the coal inlet is measured, the temperature in the coal inlet of the carbonization chamber is 950-1000°C, and the temperature measured by the temperature measuring device is above 800°C; if it is less than 500°C, it indicates that the coal inlet is blocked, and the corresponding blockage information is output to the coal loading vehicle Operate the terminal and stop the subsequent coal loading action of the coal loading truck at the same time. The invention can timely detect the blockage of the coal charging port of the coke oven carbonization chamber, avoid the blockage of the coal charging port caused by the coal loading operation, ensure the safety of the processing personnel, and reduce the coal charging port blockage caused by the processing of the coal charging operation. Environmental pollution, reduce the burden of manual cleaning.

Description

technical field [0001] The invention belongs to coke oven technology, in particular to a method for detecting the blockage of a coke oven coal charging port. Background technique [0002] The coal charging port is the only passage for the top-loading coke oven coal charging car to load the coking coal into the carbonization chamber. At present, there is no detection method for the coal charging port blockage. There is a mechanical ram-type detection device for the coke oven coal charging mouth furnace cover. The device is installed on the coal loading car. furnace cover. [0003] Problems existing in the existing furnace cover adsorption detection device: first, the device is easily deformed, and the upper limit position is deviated after the door remover removes the cover, resulting in detection failure; second, after the double-layer energy-saving heat-insulated The lower layer of the furnace cover falls off, which cannot be detected by the device, which still causes coa...

AI Technical Summary

Problems solved by technology

[0003] Problems existing in the existing furnace cover adsorption detection device: first, the device is easily deformed, and the upper limit position is deviated after the door remover removes the cover, resulting in detection failure; second, after the double-layer energy-saving heat-insulated The lower layer of the furnace cover falls off, which cannot be detected by the device, which still causes coal blocking during coal charging

[0004] The above reasons make it difficult to apply and popularize the furnace cover adsorption confirmation device at present, and the coal blocking phenomenon caused by the furnace cover not being opened normally is relatively frequent

During the production process of coke oven carbonization, free carbon accumulates at the coal inlet, sometimes forming secondary coke, which blocks the coal inlet, and coal addition at this time will also cause coal blockage

During the coal charging process of the coke oven, once the coal is blocked at the coal inlet, the coal is prone to smoke and fire at high temperature, polluting the environment

It is also very difficult to deal with coal blockage. It is necessary to retract all the devices of the coal loading car to their original positions, remove the coal loading car, and then manually clean up the piled coal. Coke and other sundries, serious environmental pollution during the process, a large amount of coal fuel flames and waste gas spill out, there are also great safety risks
