Description

Technical Field

[0001] The utility model relates to the technical field of flue gas pretreatment devices, in particular to a portable flue gas pretreatment device. Background Art

[0002] The flue gas pretreatment device effectively removes harmful substances such as particulate matter, harmful gases and moisture in the flue gas through processes such as adsorption, absorption and condensation, reducing pollution to the environment. Pretreatment before flue gas analysis and measurement can remove interfering factors such as particulate matter contamination of the gas path and sensors, and the dilution effect of water vapor on the measurement results, thereby improving measurement accuracy.

[0003] According to a portable flue gas pretreatment device disclosed on the patent website (authorization announcement CN 221207206 U), "A portable flue gas pretreatment device comprises a treatment table and a one-way air inlet portion. The front side of the treatment table is provided with an internally threaded hole (I), which is provided with an externally threaded cap (I), which is provided with a dust removal filter layer (I). The upper surface of the treatment table is provided with a handle, an air pump, an externally threaded joint (I), and an internally threaded hole (II). The air inlet end of the air pump is connected to the internally threaded hole (I) via an air intake pipe, and the air outlet end is connected to a sealing cap via a soft air pipe. A drying cylinder is threadedly connected to the upper surface of the externally threaded joint (I), and a baffle is provided at the bottom of the drying cylinder."

[0004] In view of the above description, the applicant believes that the following problems exist:

[0005] During use, the utility model utilizes the dust removal filter layer and the desiccant to remove dust and dehumidify the flue gas in turn; and when the desiccant needs to be replaced, it is only necessary to remove the cover from the top of the drying cylinder, and then remove the drying cylinder from the external threaded joint, and then pour out the desiccant, and then pour new desiccant into the drying cylinder, and then reinstall the drying cylinder on the processing table, which is convenient for replacing the desiccant. However, in actual use, when disassembling the drying cylinder, the device needs to remove the drying cylinder from the external threaded joint, and then pour out the desiccant one by one, which makes the entire disassembly of the device more cumbersome, and the replacement time is too long. In addition, during the replacement process, the device needs to stop running for a long time, which leads to reduced working efficiency, thereby further affecting the normal operation and use effect of the device. Therefore, it is necessary to improve a portable flue gas pretreatment device. Utility Model Content
