Description

Technical Field

[0001] The present application relates to an exhaust gas purification device for a temporary storage warehouse for hazardous chemicals. Background Art

[0002] Hazardous chemical temporary storage refers to a place where flammable, explosive, toxic, and hazardous materials are stored and kept. Since some substances that may produce toxic and harmful gases may be put into the storage during use, the hazardous chemical temporary storage cannot be discharged arbitrarily. Now, most of them are discharged through discharge windows, and then activated carbon is set in the discharge pipe for adsorption and purification. The biggest problem with this treatment method is that the adsorption effect of activated carbon is poor, and the replacement frequency is high, which leads to high cost of use and poor filtering effect. In addition, for different hazardous chemical temporary storages, there is a significant difference in the adsorption effect of activated carbon because they will produce completely different toxic and harmful substances. Utility Model Content

[0003] In order to solve the above problems, the present application proposes an exhaust gas purification device for a hazardous chemical temporary storage warehouse, comprising a bottom cavity, a driving fan is arranged at the upper part of the bottom cavity, an adsorption part is arranged at the upper part of the driving fan, a filter part is arranged at the upper part of the adsorption part, and an outflow channel is arranged outside the filter part; the adsorption part comprises a receiving tank body for setting the adsorption liquid, a top support plate is arranged at the upper part of the receiving tank body, a plurality of lower isolation plates are arranged in the receiving tank body, an upper isolation plate is arranged below the top setting plate, the upper isolation plate extends into the upper part of the receiving tank body, and the lower isolation plate and the upper isolation plate are arranged at intervals. The present application adopts an integrated setting method and a fan internal drive method, so that the internal gas can be led out of the hazardous chemical temporary storage warehouse, and the led air is adsorbed by the adsorption liquid set according to the hazardous chemical items, and then filtered by the filter part, and finally led out of the system through the outflow channel, ensuring the purification effect of the exhaust gas of different stored items.

[0022] When in use, the driving fan 2 is rotated to generate a vertical pressure difference, so that the exhaust gas containing pollutants enters the adsorption part 3 from the bottom cavity 1 through the driving fan 2. Since the adsorption part 3 is provided with an upper isolation plate 9 and a lower isolation plate 8, the exhaust gas flowing through it is itself turbulent, and is in full contact with the adsorption liquid in the containing tank 6 to ensure the adsorption effect, and then is exported to the outside of the system through the filter part 4 and the outflow channel 5 in turn.

[0023] In the second embodiment, if Figure 1-4As shown, an exhaust gas purification device for a temporary storage of hazardous chemicals includes a bottom cavity 1, a driving fan 2 is arranged on the upper part of the bottom cavity 1, an adsorption part 3 is arranged on the upper part of the driving fan 2, a filter part 4 is arranged on the upper part of the adsorption part 3, and an outflow channel 5 is arranged outside the filter part 4; the adsorption part 3 includes a receiving tank 6 for arranging the adsorption liquid, a top support plate 7 is arranged on the upper part of the receiving tank 6, a plurality of lower isolation plates 8 are arranged in the receiving tank 6, an upper isolation plate 9 is arranged below the top arrangement plate, the upper isolation plate 9 goes deep into the upper part of the receiving tank 6, and the lower isolation plate 8 and the upper isolation plate 9 are arranged at intervals.
