Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical waste gas treatment, in particular to a portable pharmaceutical waste gas treatment device. Background Art

[0002] In the production process of pharmaceutical intermediates, due to the chemical reactions involved, a certain amount of waste gas will be generated during the processing. Therefore, a special waste gas treatment system is required to treat and purify the waste gas before it can be discharged into the atmosphere. Waste gas purification mainly refers to the treatment of industrial waste gases such as dust particles, flue gas, odorous gases, and toxic and harmful gases generated in industrial sites.

[0003] In the related technology, a solution of an efficient odor-removing exhaust gas processor (Announcement No.: CN212974705U) was found through searching. When in use, an electric heating grid is set at the air inlet to oxidize organic matter and NO in the exhaust gas. At the same time, multiple filter layers and negative ion generators are set to remove particulate matter and dust in the air. The acidic gas in the exhaust gas is neutralized by spraying and water bathing to effectively improve the purification quality. At the same time, the setting of the shock-absorbing spring can reduce the vibration caused by the operation of the fan.

[0004] Since the dust, odor and debris in the exhaust gas are removed in the above method, however, the primary fiber filter and the activated carbon filter are prone to saturation of filtration and adsorption after long-term use, and need to be disassembled for cleaning and replacement. The above method lacks a structure that can replace the primary fiber filter and the activated carbon filter, which affects the purification effect and makes the primary fiber filter and the activated carbon filter unable to be used normally in the future. In view of this, we have launched a convenient pharmaceutical waste gas processor. Utility Model Content
