Method and system for detecting tail gas of locomotive for coal mine and storage medium

Abstract

The invention discloses a method, a device and a system for detecting tail gas of a coal mine locomotive. The method, the device and the system are used for detecting carbon monoxide in tail gas of a coal mine diesel locomotive in real time. The method comprises the steps that the locomotive tail gas is cooled through a first cooling device and a second cooling device; monitoring the temperature of the cooled locomotive tail gas; when the temperature of the cooled locomotive tail gas is smaller than a first preset temperature, the locomotive tail gas is extracted, carbon monoxide detection is conducted on the locomotive tail gas through a carbon monoxide sensor, and the first preset temperature is smaller than the maximum value of the normal working temperature of the carbon monoxide sensor. According to the method, before the tail gas of the locomotive for the coal mine is detected, the tail gas of the locomotive is cooled, so that the temperature of the tail gas of the locomotive is controlled within the working range of the carbon monoxide sensor, and the carbon monoxide in the tail gas of the diesel locomotive for the coal mine is detected in real time through the carbon monoxide sensor at the tail gas pipe of the locomotive.

Description

technical field [0001] The application relates to the technical field of tail gas monitoring, and in particular, to a detection method, system and storage medium for tail gas of a coal mine locomotive. Background technique [0002] The trackless rubber-wheeled vehicles used in coal mines are powered by diesel engines. In recent years, the country has higher and higher requirements for exhaust emissions from diesel locomotives in coal mines. Existing carbon monoxide detection methods are often detected by carbon monoxide sensors. Since carbon monoxide sensors use electrochemical principles, their maximum operating temperature does not exceed 60 degrees Celsius. The working temperature of the carbon monoxide sensor, if the locomotive exhaust gas is directly detected at the locomotive exhaust pipe in real time, it can directly cause the burning of the sensor device. At present, there is no real-time detection method for carbon monoxide emissions at the exhaust pipe of diesel l...

AI Technical Summary

Problems solved by technology

The existing carbon monoxide detection method is often detected by carbon monoxide sensor, because the carbon monoxide sensor adopts the electrochemical principle, its maximum operating temperature does not exceed 60 degrees Celsius, while the temperature of the exhaust gas of diesel locomotives used in coal mines is as high as 800-1000 degrees, far exceeding If the working temperature of the carbon monoxide sensor is detected directly at the exhaust pipe of the locomotive in real time, it will directly cause the burning of the sensor device

At present, there is no real-time detection method for carbon monoxide emissions at the tailpipe of diesel locomotives
