Description

Gas filtering device for gas detection Technical Field The application relates to the field of gas filtration, in particular to a gas filtration device for gas detection. Background In the gas detection process, since the actual gas to be detected often contains various impurities such as dust, particulates, harmful chemicals, microorganisms, and the like. The impurities can damage gas detection instruments without filtering, such as blocking sensors, corroding instrument parts and the like, and meanwhile, the existence of the impurities can interfere with detection results, so that detection data are inaccurate, and components and properties of the gas cannot be truly reflected. The gas filtering device is a device specially used for purifying the gas to be detected, and is used for removing impurities in the gas by physical, chemical and other methods and providing a pure sample for gas detection. At present, a common gas filtering device is generally composed of a shell, a filter element and other parts, and different types of impurities in gas are filtered through a plurality of filter layers. For example, particulate matter is intercepted by a fibrous filter layer, harmful chemicals are adsorbed by an activated carbon filter layer, and the like. However, after a certain period of time, the multiple filter layers of the conventional gas filter device may be gradually saturated or blocked due to adsorption and interception of impurities, and may need to be replaced or cleaned periodically to maintain the filtering effect. However, these filter devices are generally fixedly installed inside the gas detection box, and the space is relatively narrow and the structure is complex. When the filter layer is cleaned in the disassembly and assembly process, the filter layer is often required to be completed through complicated steps by means of specific tools, a plurality of fixing parts can be required to be removed, other internal components can be carefully avoided, and the like, and the whole process is time-consuming and labor-consuming, so that the workload of operators is increased, the efficiency of detection work is also reduced, and the difficulty of replacing the filter layer is greatly increased.
