This invention discloses an atmospheric environment assessment device based on carbon neutrality monitoring. The device includes a cabinet deployed in an industrial park to monitor the atmospheric environment. Inside the cabinet is a pretreatment module that separates large particulate matter from the atmosphere and dries and controls the temperature of the air. A multi-channel air inlet is located at the upper back of the cabinet, connected to the air inlet of the pretreatment module, allowing for the introduction of atmospheric samples from different locations within the industrial park. Inside the cabinet is a detection, calculation, and control module that receives the clean sample gas output from the pretreatment module and performs gas concentration monitoring and environmental data assessment. The pretreatment module contains a centrifuge, a dehydration and drying combination pipe, a filter, and a distributor, all connected in sequence. The pretreatment module achieves integrated dust removal, dehydration, and temperature control of the atmospheric sample gas, improving its purity and ensuring the accuracy of subsequent gas monitoring data.

A rectifier and faucet are provided, comprising a first cavity and a second cavity. The first cavity is connected to the second cavity via a first water level passage and a first air inlet. The second cavity is connected to the atmospheric environment via a second air inlet. Air is supplied to the first and second cavities respectively through the first and second air inlets, allowing air to contact the bubbles in the water flowing through the first and second cavities, thereby increasing the size of the bubbles. After the bubbles contact the atmosphere, the bubble walls are connected to the atmosphere. Under the action of gravity, the water film at the top of the bubbles flows downward, and the surface tension causes the water film to contract and thin, causing the bubbles to burst inside the rectifier. This reduces the bubble content in the water flow, reduces the possibility of large bubbles bursting at the outlet, improves the undesirable phenomena such as water flow interruption and shaking, and enhances the user experience.
