[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-5 , the present invention provides a technical solution: an exhaust gas treatment device based on inner layer and outer layer adsorption, including:

[0026] A housing 1, an outer layer cavity 11 is arranged inside the housing 1, an inner shell 4 is arranged inside the outer layer cavity 11, an inner layer cavity 44 is arranged inside the inner shell 4, the inner shell 4 and the housing 1 are fixedly connected, and the inner shell 4 penetrates through the housing 1;

[0027] An intake pipe 3, the intake pipe 3 is arranged inside the outer layer cavity 11, both ends of the intake pipe 3 are an input end 31 and an output end 32 respectively, the input end 31 penetrates through the housing 1, and the output end 32 communicates with the inner layer cavity 44;

[0028] An adsorption assembly, the adsorption assembly is arranged inside the inner layer cavity 44, and the adsorption assembly is used for adsorbing exhaust gas;

[0029] An outlet pipe 41, the outlet pipe 41 is arranged at the top of the inner shell 4 and communicates with the inner layer cavity 44.

[0030] The exhaust gas to be treated is input through the input end 31 of the intake pipe 3, the exhaust gas to be treated is input into the inner layer cavity 44 through the output end 32, after being adsorbed by the adsorption assembly inside the inner layer cavity 44, it is then released through the outlet pipe 41.

[0031] In this embodiment, an annular pipe 21 is arranged inside the outer layer cavity 11, a plurality of nozzles 22 are uniformly arranged on the annular pipe 21, and a drain pipe 2 communicates with the bottom of the inner shell 4.

[0032] After the exhaust gas to be treated enters the inner layer cavity 44, the annular pipe 21 communicates with an external reaction solution and sprays it through the nozzles 22 to perform preliminary treatment on the exhaust gas; the reaction solution can be selected according to the characteristics of the exhaust gas. For example, for exhaust gas with more dust, the reaction solution can be water. After the dust is precipitated, it is then discharged through the drain pipe 2.

[0033] In this embodiment, a filter screen 5 is arranged in the outer cavity 11, and the filter screen 5 is arranged above the annular pipe 21. The tail gas after preliminary treatment passes through the filter screen 5 for secondary treatment and filtration.

[0034] In this embodiment, the intake pipe 3 is provided with a spiral part 33, and the spiral part 33 is wound and fixed outside the inner shell 4. By arranging the intake pipe 3 in a spiral shape, the time for the tail gas to enter the inner cavity 44 is prolonged, so that the inner cavity 44 can fully filter the entering tail gas.

[0035] In this embodiment, the spiral part 33 is arranged above the annular pipe 21. When some tail gas is discharged, it carries a certain amount of heat. By arranging the spiral part 33 above the annular pipe 21, the tail gas wetted by the nozzle 22 can be heated, reducing the moisture in the tail gas, thereby reducing the filtration pressure on the filter screen 5.

[0036] In this embodiment, the adsorption assembly includes an outlet pipe 7, a fixed platform 9, adsorption balls 10, a first elastic member 11, a connecting pipe 12, and a second elastic member 13. The fixed platform 9 is fixedly arranged in the inner cavity 44. The adsorption balls 10 are arranged on the fixed platform 9 and are used for adsorbing and filtering the tail gas. The first elastic member 11 is arranged on the fixed platform 9, and the second elastic member 13 is arranged on the side wall of the inner shell 4, and the elastic force directions of the two are perpendicular to each other. The connecting pipe 12 is communicated with the outlet pipe 7. The outlet pipe 7 is fixedly arranged in the inner cavity 44. The connecting pipe 12 is arranged parallel to the elastic force direction of the first elastic member 11. The adsorption balls 10 can roll in the connecting pipe 12 and the outlet pipe 7, and the adsorption balls 10 can simultaneously abut against the first elastic member 11, the second elastic member 13, and the connecting pipe 12; an included angle is formed between the outlet pipe 7 and the collection platform 9.

[0037] The tail gas passes through the filter screen 5 and continues to be adsorbed and filtered by the adsorption balls 10. The adsorption balls 10 can be made of activated carbon. Since the first elastic member 11 and the second elastic member 13 are in a balanced state before the adsorption balls 10 are adsorbed, and the gravity of the adsorption balls 10 changes after adsorption, the original balance is destroyed, so that the adsorbed adsorption balls 10 are ejected into the outlet pipe 7.

[0038] In this embodiment, a feed inlet 42 is provided at the top of the inner shell 4. A placement platform 8 is fixedly arranged in the inner cavity 44. The placement platform 8 is arranged corresponding to the feed inlet 42. An inlet pipe 6 is arranged between the placement platform 8 and the fixed platform 9. The outlet pipe 7 penetrates through the inner shell 4, and a discharge tray 43 is arranged outside the inner shell 4. The discharge tray 43 is arranged corresponding to the outlet pipe 7.

[0039] Through the setting of the feed inlet 42, the new adsorption balls 10 can enter the fixed platform 9 through the placement platform 8 and the inlet pipe 6 to complete the replacement of the adsorption balls 10. A one-way valve can be set at the feed inlet 42 to prevent the tail gas from overflowing.

[0040] In this embodiment, the outlet pipe 7 penetrates through the inner shell 4, and a discharge tray 43 is arranged outside the inner shell 4, and the discharge tray 43 corresponds to the outlet pipe 7.

[0041] The adsorbed balls 10 after adsorption are exported through the outlet pipe 7 and received by the discharge tray 43. At the same time, the staff can also judge whether new adsorption balls 10 need to be put in according to the presence or absence of the adsorption balls 10 on the discharge tray 43.

[0042] The working principle and usage process of the present invention: The tail gas to be treated is input through the input end 31 of the intake pipe 3, and the tail gas to be treated is input into the inner cavity 44 through the output end 32. The annular pipe 21 is internally connected to the external reaction solution and is sprayed through the spray head 22 to perform preliminary treatment on the tail gas; the tail gas after preliminary treatment is heated by the spiral part 33 to reduce the moisture in the tail gas, and then is subjected to secondary treatment and filtration through the filter screen 5, and then is adsorbed and filtered by the adsorption balls 10. After the adsorption balls 10 are adsorbed, their gravity changes, thereby destroying the original balance, so that the adsorbed adsorption balls 10 are ejected into the outlet pipe 7 and finally received by the discharge tray 43. At the same time, the filtered tail gas is discharged through the outlet pipe 41.

[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
