Cooker flue gas pollutant on-site detection system

Abstract

The invention provides a cooker flue gas pollutant on-site detection system. The system comprises a flue gas sampling module, an air dilution module and an analysis module; the flue gas sampling module comprises a sampling bent pipe, a T-shaped conversion connector and a sampling straight guide pipe; the sampling bent pipe is connected to a first port of the T-shaped conversion connector; the air dilution module is connected to a second port of the T-shaped conversion interface through a silicone tube; and the sampling straight guide pipe is connected to a third port of the T-shaped conversion connector; the flue gas sampling module collects flue gas in a civil cooker chimney through the sampling bent pipe; the air dilution module sends air used for diluting the flue gas into the sampling straight guide pipe through the T-shaped conversion connector; and the sampling straight guide pipe transmits the diluted flue gas to the analysis module for pollutant detection. The civil cooker flue gas pollutant emission on-site detection system is simple, convenient and efficient, and can carry out 24-hour dilution sampling measurement in the whole process; the phenomenon of filter membrane overload in the sampling process is avoided; and the defect that a sensor is short in service life is overcome.

Description

technical field [0001] The invention relates to detection technology, in particular to an on-site detection system for stove smoke pollutants. Background technique [0002] With the continuous improvement of people's living standards and the rapid development of industry, my country's energy consumption has increased sharply, and a large amount of fossil energy consumption and unreasonable combustion have caused serious air pollution. In recent years, air pollution caused by flue gas pollutants emitted by residents' decentralized heating has become more and more serious, especially in northern areas where frequent smog weather has brought great threats to people's lives and health. The survey found that 80% of the residents burn coal for heating, and the burning of scattered coal for heating causes serious pollutant emissions, which are as high as 5-10 times that of thermal power plants. An advanced monitoring system is an important supporting condition for realizing energy...

AI Technical Summary

Problems solved by technology

Due to poor combustion stability and low flue gas emission flow rate when civilian stoves burn solid fuel, this results in large errors in sampling test data, and due to the high flue gas temperature and pollutant concentration, traditional direct sampling will also damage test equipment, shortening the service life of the instrument
