Technical Field

[0001] The utility model belongs to the technical field of aluminum foil processing, and specifically relates to an exhaust gas treatment device for an aluminum foil processing workshop. Background Art

[0002] When aluminum foil is dried or processed, the rolling oil remaining on its surface will produce a large amount of waste gas containing oil mist due to heat. If not treated, it will seriously pollute the air in the processing workshop, and the untreated waste gas will be discharged to the outside world and damage the ecological environment.

[0003] However, in the prior art, the relevant devices generally treat the exhaust gas by dust filtration or activated carbon adsorption, etc., and these methods are difficult to completely eliminate the oil mist contained in the exhaust gas, and the oil mist will be atomized into oil droplets and accumulate in the device in large quantities and be difficult to clean. Therefore, an exhaust gas treatment device for an aluminum foil processing workshop is proposed. Utility Model Content

[0007] The purification component includes an oil removal component that can provide an accumulation area for oil droplets formed by oil atomization and decompose the accumulated oil, a separation component that can intercept small mist oil droplets in the exhaust gas, and a purification component that can filter and adsorb the exhaust gas after oil removal treatment.

[0008] Preferably: the oil removal component comprises a reaction box fixedly mounted on the air intake assembly, the front and rear sides of the reaction box are fixedly mounted with windows, a frame is fixedly connected above the reaction box, and an ultraviolet lamp is fixedly mounted in the frame.

[0027] In this embodiment: the purification component 2 includes an oil removal component that can provide an accumulation area for oil droplets formed by oil atomization and decompose the accumulated oil liquid, a separation component that can intercept small oil droplets in the mist in the exhaust gas, and a purification component that can filter and adsorb the exhaust gas after oil removal treatment. The oil removal component includes a reaction box 201 fixedly installed on the air intake component 1, and windows 202 are fixedly installed on the front and rear sides of the reaction box 201. A frame 203 is fixedly connected to the top of the reaction box 201, and an ultraviolet lamp 20 is fixedly installed in the frame 203. 4. The separation part includes a separation bin 205 fixedly connected to one side of the reaction box 201, a metal oil separator 206 is fixedly installed in the separation bin 205, the purification component 2 also includes a feed plug 207 fixedly connected to the feed end of the reaction box 201, a drain valve 208 is fixedly connected to the discharge end of the reaction box 201, and the purification part includes a purification box 209 fixedly connected above the reaction box 201, an activated carbon adsorber 210 is fixedly installed in the purification box 209, and a filter 211 is arranged below the activated carbon adsorber 210;

[0028] The reaction box 201 is a hollow structure with one side and the top open, and the feed end and the discharge end on the other side thereof are at different lateral positions and heights, and the viewing window 202 is made of transparent material;

[0029] The reaction box 201 is used to contain the treatment liquid to treat the oil accumulated therein, the liquid level and oil retention in the reaction box 201 are observed through the window 202, the ultraviolet lamp tube 204 is installed on the upper part of the reaction box 201 through the frame 203, the ultraviolet lamp tube 204 emits an ultraviolet beam to perform photolysis and oxidation reaction on the oil smoke, so that the oil droplets are converted into water and carbon dioxide, and the metal oil separator 206 installed at a certain height on one side of the reaction box 201 through the separation chamber 205 is used to intercept small droplets of oil mist in the exhaust gas that continuously enters the separation chamber 205 and make them converge and flow into the bottom area of ​​the reaction box 201, the feed end of the reaction box 201 is closed by the feed plug 207, the discharge end of the reaction box 201 is closed by the drain valve 208, and the activated carbon adsorber 210 and the filter 211 are installed at different heights above the reaction box 201 through the purification box 209.

After the adjustment is completed, the induced draft fan 3 is operated. The induced draft fan 3 after operation can sequentially extract the air in the purification box 209, the reaction box 201, the separation chamber 205, the air intake pipe 104, and the air intake hopper 102, so that negative pressure is formed in the device, thereby sucking the external waste gas into the device and flowing along a fixed path;

In addition, the oil that is not eliminated by the reaction will be photo-oxidized under the continuous irradiation of the ultraviolet lamp 204. When the liquid level in the reaction box 201 is too high, the liquid without oil in the lower layer of the mixed liquid in the reaction box 201 can be properly discharged through the drain valve 208, and then an appropriate amount of treatment liquid can be added to the reaction box 201 to avoid excessive accumulation of oil in the reaction box 201.
