Diesel engine tail gas quality monitoring system

Abstract

The invention discloses a diesel engine tail gas quality monitoring system, and the system mainly comprises a controller, a key, a display module, an alarm module, a humidity sensor, a temperature sensor, a storage unit, a dust sensor, a methyl aldehyde sensor, a gas sensor, an amplification module, an analog/digital conversion module, and an air purification device. The system is characterized in that the key, the humidity sensor and the temperature sensors are respectively connected with the controller; the display module, the alarm module and the air purification device are respectively connected with the controller; the storage unit is connected with the controller; the analog/digital conversion module is connected with the controller; the amplification module is connected with the analog/digital conversion module; and the dust sensor, the methyl aldehyde sensor and the gas sensor are connected with the amplification module.

Description

technical field [0001] The invention relates to the field of tail gas quality monitoring, in particular to a diesel engine tail gas quality monitoring system. Background technique [0002] With the development of industry, the living environment of human beings is deteriorating day by day, and the air quality is also declining. Therefore, the detection of air quality has attracted people's attention day by day. The main pollutants are formaldehyde, ammonia, benzene, radon, etc. When these pollutants reach a certain concentration, they will cause great damage to the human body, and even cause death. [0003] The detection of exhaust air quality usually requires the use of special detection equipment, and the existing exhaust air quality detection devices are single, and can only detect a specific gas, and multiple gases are detected at the same time, which requires a variety of equipment. It occupies a large area, is inconvenient to use, and most of these devices are expensi...

[0003] The detection of exhaust air quality usually requires the use of special detection equipment, and the existing exhaust air quality detection devices are single, and can only detect a specific gas, and simultaneously detect multiple gases, which requires a variety of equipment. It occupies a large area, is inconvenient to use, and most of these devices are expensive, so they are not suitable for exhaust gas quality detection
