Intelligent power plant carbon emission monitoring system and monitoring method thereof

Abstract

The invention discloses an intelligent power plant carbon emission monitoring system and a monitoring method thereof.The intelligent power plant carbon emission monitoring system comprises a chimney, a flow equalizing structure is fixedly installed in the chimney, a monitoring structure is fixedly installed in the chimney and located above the flow equalizing structure, the flow equalizing structure comprises a flow equalizing box, and the top of the flow equalizing box is open; a partition plate is fixedly installed in the flow equalizing box, and a middle vertical pipe is installed at the circle center of the partition plate in a penetrating and inserting mode. According to the intelligent power plant carbon emission monitoring system and the monitoring method thereof, discharged flue gas is intensively guided in, disordered and then guided into the flow equalizing cylinder in a staggered manner, so that the flue gas at different positions can be staggered together and uniformly mixed, the concentration of carbon dioxide in the flue gas is more uniform, and the carbon emission of the power plant is more uniform. It is guaranteed that follow-up carbon dioxide concentration detection data is representative, detection errors are reduced, and a plurality of carbon dioxide concentration sensors do not need to be installed.

Description

technical field [0001] The invention relates to the technical field of smart power plants, in particular to a carbon emission monitoring system for smart power plants and a monitoring method thereof. Background technique [0002] A power plant refers to a power plant that converts some form of raw energy into electrical energy for fixed facilities or transportation, such as thermal power, hydraulic power, steam, diesel or nuclear power plants, etc. Carbon emissions generally refer to greenhouse gas emissions, which cause the greenhouse effect and increase global temperatures. While the earth absorbs solar radiation, it also radiates heat to the outer space, and its heat radiation is dominated by long-wave infrared rays of 3-30 μm. When such long-wave radiation enters the atmosphere, it is easily absorbed by some gas molecules with larger molecular weight and stronger polarity. Since the energy of infrared rays is low, it is not enough to break the bond energy of molecules....

AI Technical Summary

Problems solved by technology

[0003] At present, when testing the carbon emissions of power plants, the commonly used method is single-point detection. However, the chimneys of power plants are large in diameter. When the fixed-point detection method only monitors the carbon dioxide concentration at a certain position in the flue gas, the detected value is not representative due to the large diameter of the chimney, and there is a large error in the detection of carbon emissions. A detection device, which will lead to a very complicated system, which is not conducive to the calculation of carbon emission data, and will also increase the monitoring cost
