Remote emission monitoring system for resident coal-fired heating stove based on 4G network

Abstract

The invention relates to a remote emission monitoring system for a resident coal-fired heating stove based on a 4G network. The system comprises a flue gas dilution sampling module, and an output endof the flue gas dilution sampling module is sequentially connected with a flue gas distribution module, a data acquisition module, a data transmission module and a data analysis management platform; apower module is used for supplying power to all the modules; the flue gas dilution sampling module, the flue gas distribution module, the data acquisition module, the data transmission module and thepower module are installed on the distributed resident winter coal-fired heating stove, and the data analysis management platform is installed in a provincial and municipal fixed monitoring room. Bymeans of the system, the combustion state and emission performance of the resident coal-fired heating stove can be monitored in real time, wide-range data acquisition and analysis can also be achievedthrough the 4G network, and through the link and communication with a database technology and meteorological environmental protection data, environmental protection monitoring within a wider range and a deeper field in vast rural areas is achieved.

Description

technical field [0001] The invention relates to the field of atmospheric environmental pollution monitoring, in particular to a 4G network-based remote monitoring system for residents' coal-fired heating stove emissions. Background technique [0002] my country's current energy structure and social development level determine that for a certain period of time in the future, coal-fired stoves will still be the main heating method for residents in northern my country in winter, and urban residents will begin to enjoy the cleanliness and warmth brought by central heating, but there will still be about 1.5 Hundreds of millions of rural households use scattered heating for heating. On average, each household burns more than two tons of coal in one winter. The coal is not fully burned, but is burned slowly with closed fires, producing a lot of smoke and harmful gases. However, at present, due to the wide coverage of coal-fired heating, difficult supervision, and the lack of an effe...

[0002] my country's current energy structure and social development level determine that for a certain period of time in the future, coal-fired stoves will still be the main heating method for residents in northern my country in winter, and urban residents will begin to enjoy the cleanliness and warmth brought by central heating, but there will still be about 1.5 Hundreds of millions of rural households use scattered fires for heating. On average, each household burns more than two tons of coal in one winter, and the coal is not fully burned, but is burned slowly with closed fires, producing a lot of smoke and harmful gases

However, at present, due to the wide coverage of coal-fired heating, difficult supervision, and the lack of an effective emission detection system, the air pollution caused by rural residents' coal-fired heating is becoming more and more serious, and the governance is also facing great challenges

[0003] In the field of heating stove monitoring abroad, high-precision flue gas analyzers based on infrared sensors or electrochemical sensors and fine particle detectors based on spectrophotometers are mostly used. However, due to expensive instruments and complicated operations, it is difficult to apply them in northern my country. Real-time monitoring of pollutant emission performance of rural residents' coal-fired heating stoves in winter

The domestic development of heating stove monitoring is relatively late, and most of the monitoring is carried out under laboratory conditions. However, the quality of residential coal-fired heating stoves is uneven. The characteristics of large number of users and wide geographical distribution in the application make it difficult to monitor pollutant emission performance in real time
