Coke oven automatic release ignition control device and control method

Abstract

The present invention relates to a coke oven automatic bleed ignition control device, which is characterized in that the control device includes a controller, a bleed ignition side wireless communication device, a coal stoker side wireless communication device, a 1# induced draft fan state detection signal, a 2# The state detection signal of the induced draft fan, the gas pipeline, the gas detection device, the redundant ignition device and the electric control valve of the gas pipeline. The wireless communication device on the ignition side is installed on the controller. On the coal car, the coal loading car transmits the furnace number information and coal feeding status information to the controller through the wireless communication device, and the control device automatically judges whether to carry out the release ignition through a reliable control method, so as to avoid the overflow of raw coal gas that does not pass the release ignition leading to serious air pollution incidents.

Description

technical field [0001] The invention relates to a coke oven automatic release ignition control device and a control method, which belong to the technical field of electric control. Background technique [0002] The coke oven release ignition device is installed on the gas collecting pipe on the roof of the coke oven. Its structure diagram and trigger flow chart are as follows: figure 1 and figure 2 As shown, when the pressure regulating system of the gas collecting pipe 4 is abnormal, the high-pressure raw coal gas in the gas collecting pipe will be released through the release tower 6 and ignited and burned, so as to prevent the unburned high-pressure raw gas from rushing through the rising pipe 5 and directly discharged into the atmosphere cause serious environmental pollution accidents. In actual use, due to the insufficient interlock protection of the device and the low degree of automation, the following problems have occurred: 1) When the coal charging car 3 is char...

Problems solved by technology

In actual use, due to the insufficient interlock protection of the device and the low degree of automation, the following problems have occurred: 1) When the coal charging car 3 is charging coal on the top of the coke oven 1, the gas pressure fluctuation of the raw coal in the nearby gas collecting pipe 4 is relatively large. Large, it will lead to frequent and accidental triggering of the release ignition device 6, and the released raw gas will cause further abnormal fluctuations in the pressure of the gas collection pipe; The induced draft fan 8 and the 2# induced draft fan 9 work together to keep the air pressure of raw coal in the air collecting pipe 4 at about 0-300Pa through the air collecting pipe pressure regulating mechanism. fan failure), the pressure of the raw gas in the gas collecting pipe 4 will rise sharply, and before the release of the ignition device, a large amount of high-pressure raw gas will be discharged from the cover of the rising pipe 5, resulting in serious air pollution incidents; 3) After ignition and emission, due to the failure of the device itself, the released raw gas cannot be reliably ignited, resulting in serious air pollution incidents

In the case of increasingly strict environmental protection control, the non-automatic control and abnormality of the ignition and release device will bring huge hidden dangers to safe production and environmental protection
