A second spray structure is located above the gas lifting structure. A second gas lifting structure is located above the second spray structure. An adsorption structure is located above the second gas lifting structure.

[0006] A further improvement of the ethyl acetate waste gas recovery device of this utility model is that the reaction shell includes a lower section, a middle section and an upper section, the spray structure is arranged in the lower section, the gas lifting structure, the second spray structure and the second gas lifting structure are arranged in the middle section, and the adsorption structure is arranged in the upper section.

[0007] A further improvement of this utility model of an ethyl acetate waste gas recovery device is that the gas lifting structure and the second gas lifting structure have the same structure, including a base plate, a perforation on the base plate, an extension plate extending upward from the perforation, and the upper end of the extension plate being connected to a conical plate by a spaced connecting rod.

[0008] A further improvement of this utility model of an ethyl acetate waste gas recovery device is that a drain pipe is provided at the bottom of the lower section, and a second drain pipe is provided at the bottom of the middle section.

[0009] A further improvement of this utility model of an ethyl acetate waste gas recovery device is that a monitoring structure is provided below the gas lifting structure, and the monitoring structure is located in the middle section.

[0010] A further improvement of this utility model of an ethyl acetate waste gas recovery device is that the second drain pipe is connected to the intermediate pool, and the intermediate pool is connected to the spray structure.

[0018] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0020] like Figure 1 As shown, an ethyl acetate waste gas recovery device includes a first treatment structure 1, which includes a treatment box containing a liquid storage tank. A mesh plate is rotatably connected inside the treatment box, passing through the liquid storage tank. This structure is an existing structure. Further, the first treatment structure is connected to a second treatment structure, which includes a reaction shell. A spray structure 5 is provided on the reaction shell, a rising gas structure 6 is provided above the spray structure, a second spray structure 7 is provided above the rising gas structure, a second rising gas structure 8 is provided above the second spray structure, an adsorption structure 9 is provided above the second rising gas structure, and an outlet is provided above the reaction shell.

[0021] Furthermore, the reaction shell includes a lower section 2, a middle section 3, and an upper section 4. A spray structure is located in the lower section, a gas lifting structure, a second spray structure, and a second gas lifting structure are located in the middle section, and an adsorption structure is located in the upper section. The sections are connected by connectors, and sealing gaskets can be designed at the connections. The connections can be designed as flange-like structures. The modular structure allows for selective addition of the middle section, improving applicability.

[0022] Furthermore, the air-lifting structure and the second air-lifting structure are identical in structure, including a base plate 10, which has a perforation. An extension plate 11 is provided at the perforation and is extended upwards. The upper end of the extension plate is connected to the conical plate 12 by spaced connecting rods (not shown in the figure).

[0023] The bottom of the lower section is equipped with a drain pipe, and the bottom of the middle section is equipped with a second drain pipe.

[0024] A monitoring structure 13 is located below the air-lifting structure, in the middle section. This monitoring structure is used to adjust the second spray structure.

[0025] The second drain pipe is connected to the intermediate tank, which in turn is connected to the spray structure. The liquid collected after use of the second spray structure can be reused, improving energy efficiency.

[0026] The working principle of this invention is as follows: the collected ethyl acetate waste gas enters the first treatment structure, where it is mixed with water to reduce the concentration of ethyl acetate in the waste gas. Then, it enters the second treatment structure, where a spray structure sprays water mist to contact the waste gas and further remove ethyl acetate. The second spray structure is selected to operate based on the ethyl acetate content monitoring results. Finally, an adsorption structure further adsorbs ethyl acetate in the waste gas, achieving a better treatment effect.

[0027] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
