Description

Technical Field

[0001] This utility model relates to the field of activated carbon adsorption waste gas treatment equipment, specifically an activated carbon adsorption waste gas treatment equipment. Background Technology

[0002] Waste gas refers to toxic and harmful gases emitted by humans during production and daily life, especially those emitted by chemical plants, steel plants, pharmaceutical plants, coking plants, and oil refineries. These waste gases have strong odors and seriously pollute the environment and affect human health.

[0003] For example, the authorized patent (exhaust gas treatment equipment) with publication number CN221713829U includes a placement plate, an exhaust gas treatment equipment body, and a filter screen. The bottom of the exhaust gas treatment equipment body and the top of the placement plate are fixedly connected. The filter screen is located on the front side of the exhaust gas treatment equipment body, and the back of the filter screen contacts the front side of the exhaust gas treatment equipment body. A first fixing plate is fixedly connected to the front side of the left side of the exhaust gas treatment equipment body, and a first connecting block is fixedly connected to the front side of the first fixing plate. A second fixing plate is fixedly connected to the front side of the right side of the exhaust gas treatment equipment body, and a limit frame is fixedly connected to the front side of the second fixing plate. This solves the problem that when a lot of impurities accumulate on the filter screen, the filtration effect of the filter screen is poor, and the filter screen cannot be cleaned during operation. This reduces the problem of poor impurity filtration effect of the filter screen, and the inconvenience of the filter screen being unremovable and difficult for operators to clean.

[0004] The aforementioned existing waste gas treatment process cannot be circulated, resulting in incomplete waste gas treatment and affecting the treatment effect. Furthermore, the waste gas cannot be adsorbed and purified multiple times, leading to low purification efficiency. In addition, the structure is relatively bulky and inconvenient to operate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an activated carbon adsorption waste gas treatment device, comprising a fan, an upper purification cylinder, an activated carbon adsorption purification box, and a lower purification cylinder.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figure 1-4 This utility model provides an embodiment of an activated carbon adsorption waste gas treatment device, comprising a fan 2, an upper purification cylinder 7, an activated carbon adsorption purification box 8, and a lower purification cylinder 9. The activated carbon adsorption purification box 8 has an upper purification cylinder 7 and a lower purification cylinder 9 at its two ends. The upper purification cylinder 7 has an upper air pipe 15 at its top, and the lower purification cylinder 9 has an air inlet pipe 12 at its bottom. A waste gas inlet head 13 is located on one side of the air inlet pipe 12. A support frame 3 is located on one side of the activated carbon adsorption purification box 8, and a fan 2 is located on one side of the top of the support frame 3. A chimney 1 is located on the top of the fan 2. The waste gas undergoes three purification processes through the activated carbon adsorption purification box 8, the upper purification cylinder 7, and the lower purification cylinder 9. The waste gas is introduced into the air inlet pipe 12 through the waste gas inlet head 13, and the exhaust of the waste gas is controlled by the fan 2.

[0022] The support frame 3 is provided with a support plate 4 at the bottom, and a support base 5 is provided at the bottom of the support plate 4. The support plate 4 provides support for raising the support frame 3, and the support base 5 provides stable support for placing the support plate 4.

[0023] The activated carbon adsorption purification box 8 is equipped with activated carbon packing 14 inside. Both ends of the activated carbon adsorption purification box 8 are equipped with guide ports. The activated carbon packing 14 is used to adsorb and purify the waste gas. The upper purification cylinder 7 and the lower purification cylinder 9 are both equipped with activated carbon adsorption rods 19 inside. The upper purification cylinder 7 and the lower purification cylinder 9 are connected to the inner cavity of the activated carbon adsorption purification box 8. The activated carbon adsorption rods 19 are used to adsorb and purify the waste gas.

[0024] The upper air pipe 15 is connected to one side of the fan 2 through the exhaust pipe 6. The upper air pipe 15 is equipped with an exhaust gas detection box 18. A diversion pipe 17 is provided on one side of the upper air pipe 15. A control valve 16 is provided on the diversion pipe 17.

[0025] The top of the exhaust gas inlet head 13 is provided with a return pipe 11. The return pipe 11 is connected to the diversion pipe 17 through the return pump 10. The return pipe 11 is used to control the return of exhaust gas, so that the exhaust gas is circulated and purified.

[0026] Working principle: During use, the exhaust gas is introduced into the inlet pipe 12 through the exhaust gas inlet head 13, and then into the lower purification cylinder 9 through the inlet pipe 12. The exhaust gas undergoes primary adsorption purification through the activated carbon adsorption rods 19 inside. The exhaust gas after primary purification is discharged into the activated carbon adsorption purification box 8, where it undergoes secondary adsorption purification through the activated carbon packing 14 inside the activated carbon adsorption purification box 8. The exhaust gas after secondary adsorption purification is discharged into the upper purification cylinder 7 for tertiary purification. The exhaust gas after tertiary purification is detected by the exhaust gas detection box 18 in the upper air pipe 15, and the opening and closing of the diversion pipe 17 is controlled by the control valve 16. The return pump 10 controls the exhaust gas that is not thoroughly purified to flow back into the exhaust gas inlet head 13 through the return pipe 11 for circulation purification until the exhaust gas is completely purified. Then, it is transported to the fan 2 through the exhaust pipe 6 and discharged outdoors through the chimney 1.
