The utility model discloses a coal gas pressure stabilizing control device for a blast furnace coal injection and pulverizing system. A waste gas pipeline is provided with a waste gas fan, a waste gas electric regulating valve, a waste gas flowmeter and a waste gas pressure transmitter; a coal mill inlet temperature thermal resistor and a coal mill inlet pressure transmitter are arranged on the outlet pipeline; a coal gas pressure transmitter, a coal gas flowmeter and a coal gas electric control valve are arranged on the coal gas pipeline, and an outlet temperature thermocouple and an outlet pressure transmitter are further arranged on the outlet pipeline; a waste gas carbon monoxide detector and a waste gas oxygen content detector are arranged on the waste gas pipeline; and a gas pneumatic quick switching valve, a gas electric blind plate valve, a gas electric butterfly valve and a carbon monoxide heat conduction type gas analyzer are arranged on the gas pipeline, and the number of the gas electric control valves is larger than or equal to two. According to the utility model, the gas regulating valve or the bypass pipeline three-valve group is additionally arranged, so that a monitoring instrument is perfected, and the gas flow and pressure are accurately controlled.

This invention discloses a method and apparatus for compensating detection data of a carbon monoxide detector. The method includes: acquiring first operating data sent by a target detector, the first operating data including multiple first sensitivities and multiple first operating times of the target detector, with each first sensitivity corresponding to a specific first operating time; determining the operating stage of the target detector based on the first operating data sent by the target detector, the operating stage including at least one of an early stage, a middle stage, and a late attenuation stage; acquiring a sensitivity attenuation model corresponding to the target detector based on the operating stage of the target detector; and determining a target compensation value for the target detector based on the sensitivity attenuation model, the target compensation value being sent to the target detector to compensate for the detected carbon monoxide concentration. By implementing the method in this application, it is beneficial to improve the accuracy of carbon monoxide concentration detection.
