Description

TECHNICAL FIELD

[0002] The gas filter is a filter device widely used in the fields of chemical industry and pharmacy, and is mainly used for filtering mechanical impurities in gases such as compressed air and nitrogen. In actual chemical production processes, sometimes due to reasons such as saturation of a gas power unit or liquid leakage, part of water vapor is mixed into the gas pipeline, and the gas flows fast in the pipeline. It is known that the conventional gas filter cannot observe and feedback the sudden appearance of water in the gas in real time. For example, the low-resistance high-efficiency air filter disclosed in patent 201921965487.1 mainly includes a filter main body, a filter core, a filter core support frame, a mounting mechanism and a connecting mechanism, and air is filtered through the filter core. However, it cannot detect the moisture in the air. When carrying out chemical research and development pilot experiments, there are many experimental influencing factors, and water is one of the many influencing factors. Timely feedback on the water content of the gas entering the reaction kettle is of great significance for reducing external water introduction and investigating the introduction path and position of water pollution after abnormal reaction.
