Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of carbon emission detector, especially to a carbon emission detection early warning instrument. BACKGROUND

[0002] Carbon emission detector, also known as carbon emission monitor or carbon emission analyzer, is a device for monitoring and measuring the concentration of carbon dioxide CO2 in the air. Carbon emission detector mainly uses infrared spectroscopy technology to measure the absorption of infrared light by carbon dioxide molecules in the air to calculate the concentration of carbon dioxide. This technology is based on the specific absorption characteristics of carbon dioxide molecules to infrared light, so it can determine the amount of carbon dioxide in the air according to their absorption of infrared light. Carbon emission detector is usually composed of a probe, a signal processor, a display, and a power supply. Carbon emission detector is an important environmental monitoring device with wide application prospects and development potential.

[0003] A carbon emission detection device for industrial areas is disclosed in Chinese patent CN215953549U, which includes a wind collecting cavity, a detection cavity, and a detector. The wind collecting cavity is welded to the top end of the detection cavity, and the lower end of the detection cavity is welded to a flange plate. The flange plate is fixed to the surface of a building or object in the detection area. A wind collecting fan is installed in the wind collecting cavity, and the lower end of the wind collecting fan is rotatably installed in the detection cavity. The detection cavity is divided into a power area and a detection area. A wind collecting fan power mechanism is installed in the power area, and the wind collecting fan power mechanism drives the wind collecting fan to rotate. An acceleration air inlet fan and a detector are installed in the detection area. The utility model sets a horn-shaped wind collecting cavity with a larger wind collecting range. The wind collecting fan installed in the wind collecting cavity is driven by a motor to accelerate the collection of environmental gas and the amount of wind. The acceleration air inlet fan in the detection cavity can quickly send the collected gas into the detection air tank in the detection cavity to ensure the density of the gas in the detection air tank and improve the detection effect and accuracy of the detector.

[0004] The existing technical solution in the above has the following defects: The above-mentioned industrial area carbon emission detector is mainly used for real-time monitoring of carbon emission data to help managers understand the carbon emission situation. However, many existing carbon emission detectors do not include early warning and warning functions in design and function, which to some extent limits their effect in actual application. Carbon emission detectors without early warning and warning functions cannot timely detect carbon emission abnormalities, which may lead to potential environmental problems and safety risks. Without the support of early warning and warning functions, managers need to manually analyze data, which increases workload and time cost and reduces management efficiency. Therefore, we need an industrial area carbon emission detector with early warning function. UTILITY MODEL CONTENTS
