DETAILED DESCRIPTION

[0016] The technical solutions of the present application will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0017] It is specified that the orientation concepts of "left", "right", "up", "down", "front", "back", "inner" and "outer" in the following solutions are relative directions, which will not be listed one by one.

[0018] The active carbon box structure for treating waste gas comprises a body 12. Figure 1 The body 12 is provided with an air inlet and an air outlet at the left and right ends respectively. The air inlet is detachably provided with an air inlet cover 1, and the air outlet is detachably provided with an air outlet cover 7. The body 12 is sequentially provided with a primary efficiency filtering bag 4 and an active carbon filtering assembly from left to right. The air inlet, the primary efficiency filtering bag 4, the active carbon filtering assembly and the air outlet are sequentially communicated.

[0019] The body 12 is provided with an access door 3, and the bottom of the body 12 is provided with a base 2.

[0020] The active carbon filter assembly comprises two active carbons 6 arranged in parallel and vertically. The active carbons 6 are matched in size and shape with the interior of the body 12. The active carbons 6 are arranged in sealing connection with the body 12. The active carbons 6 are provided with wind baffles 5 on both sides. The wind baffles 6 are arranged in sealing connection with the inner wall of the body 12 and are matched in size and shape with the interior of the body 12. The two active carbons 6 are provided with wind baffles 5 arranged at the center of the active carbons 6 and sealing connected with the active carbons at the upper and lower ends.

[0021] The exhaust gas enters from the air inlet, is firstly processed by the primary filter bag 4, and the primary filter bag 4 filters out the particulate matters in the exhaust gas, so that the particulate matters are prevented from adhering to the surface of the active carbon 6 and causing the adsorption capacity of the active carbon 6 to be poor and the maintenance cost to be high. After the exhaust gas is discharged from the primary filter bag 4, the exhaust gas enters the active carbon filter assembly. Due to the blocking of the wind baffles 5, the exhaust gas needs to pass through the active carbons on both sides, so as to leave the active carbon filter assembly and be adsorbed and processed twice by the active carbons 6.

[0022] For those skilled in the art, more wind baffles 5 can be arranged between the active carbons 6 and the inner wall of the body 12, and more wind baffles 5 can be arranged between the two active carbons 6, so as to increase the number of times that the exhaust gas passes through the active carbons 6 and improve the filtering effect.

[0023] As a further improvement of the utility model, various new embodiments can be provided according to the above cases.

[0024] As a second embodiment of the utility model, on the basis of the embodiment 1, the body 12 is provided with an exhaust gas monitoring member 8 arranged between the air outlet and the active carbon filter assembly. Figure 2 The body 12 is provided with an air return outlet 9. The air return outlet 9 is communicated with the primary filter bag 4 through a return pipe 10. The body 12 is rotatably provided with a baffle 11 for sealing the air outlet or the air return outlet 9. The body 12 is provided with a rotary motor for driving the baffle 11 to rotate and seal the air outlet or the air return outlet 9. The rotary motor is signal connected with the exhaust gas monitoring member 8.

[0025] When the exhaust gas monitored by the exhaust gas monitoring member 8 reaches the emission standard, the rotary motor is signaled to drive the baffle 11 to rotate and open the air outlet, and the air return outlet 9 is sealed, so that the exhaust gas is directly discharged from the air outlet; when the exhaust gas monitored by the exhaust gas monitoring member 8 does not reach the emission standard, the rotary motor is signaled to drive the baffle 11 to rotate and open the air return outlet 9, and the air outlet is sealed, so that the exhaust gas is returned to the primary filter bag 4 through the return pipe 10 for reprocessing.

[0026] The above merely describes preferred embodiments of the present application, and it should be understood that the present application is not limited to the forms disclosed herein, and should not be considered as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concepts described herein, through the above description or related technical or knowledge.
