Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment, and in particular to a tower-type activated carbon adsorption device. Background Technology

[0002] A tower-type activated carbon adsorption device is a vertical or horizontal columnar device filled with activated carbon material. When waste gas comes into contact with the activated carbon, pollutants are adsorbed and concentrated in the carbon pores, thereby achieving the purpose of purification.

[0003] Most existing tower-type activated carbon adsorption devices only have a separate waste gas treatment channel. Sometimes, even when the amount of waste gas to be treated is small, all the activated carbon materials are needed, which is wasteful. Moreover, the machine must be stopped before the activated carbon materials can be disassembled and replaced, which is troublesome and inconvenient. Utility Model Content

[0004] The purpose of this utility model is to solve the following problems existing in the prior art: Most existing tower activated carbon adsorption devices only have a separate waste gas treatment channel. Sometimes, even when the amount of waste gas to be treated is small, all the activated carbon materials need to be used, which is wasteful. Moreover, the machine needs to be stopped before the activated carbon materials can be disassembled and replaced, which is troublesome and inconvenient.

[0005] To address the problems existing in the prior art, this utility model provides a tower-type activated carbon adsorption device, including an adsorption device body. An air inlet and an air outlet are respectively provided on both sides of the adsorption device body. A partition component is provided inside the adsorption device body. A first air duct and a second air duct are respectively provided on both sides of the partition component. A first activated carbon component is provided at the first air duct, and a second activated carbon component is provided at the second air duct.

[0006] Furthermore, a flow monitoring component is provided at the air inlet duct of the air inlet, which is used to monitor the flow rate of exhaust gas in the air inlet duct during use.

[0007] Furthermore, a first air valve is provided at the air duct opening near the air inlet of the first air duct, and the first air valve is electrically connected to the flow monitoring component.

[0008] Furthermore, a second air valve is provided at the air duct opening near the air inlet of the second air duct, and the second air valve is electrically connected to the flow monitoring component.

[0009] Furthermore, the adsorption device body is equipped with inspection plates at both the front and rear, which are used to replace and maintain the activated carbon components during use.

[0010] Furthermore, the inspection plate at the front of the adsorption device body corresponds to the first activated carbon assembly, and the inspection plate at the rear of the adsorption device body corresponds to the second activated carbon assembly.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention uses a flow monitoring component on the air inlet duct to detect the flow rate of exhaust gas. If the flow rate is low, either the first or second air valve will be closed. At this time, the exhaust gas entering the adsorption device will only enter the other open air duct and be purified by the activated carbon component in the open air duct. This avoids consuming the activated carbon component in the closed air duct, making reasonable use of resources and reducing subsequent maintenance costs. Furthermore, when disassembling and replacing the activated carbon in the later stages, there is no need to stop the machine. Simply close the air valve at the current position to perform the disassembly and replacement maintenance work, increasing the practicality of this device. Attached Figure Description

[0017] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation details without creative effort are all within the protection scope of this invention.

[0018] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0019] Example 1

[0020] like Figure 1-3 As shown, a tower-type activated carbon adsorption device includes an adsorption device body 3. An air inlet 1 and an air outlet 4 are respectively provided on both sides of the adsorption device body 3. An isolation component 7 is provided inside the adsorption device body 3. A first air duct 9 and a second air duct 11 are respectively provided on both sides of the isolation component 7. A first activated carbon component 8 is provided at the first air duct 9, and a second activated carbon component 10 is provided at the second air duct 11.

[0021] In this embodiment, a flow monitoring component is provided at the air inlet duct of the air inlet 1. When in use, it is used to monitor the flow rate of the exhaust gas in the air inlet duct. A first air valve 5 is provided at the air duct opening of the first air duct 9 near the air inlet 1. The first air valve 5 is electrically connected to the flow monitoring component. A second air valve 6 is provided at the air duct opening of the second air duct 11 near the air inlet 1. The second air valve 6 is electrically connected to the flow monitoring component. Inspection plates 2 are provided at the front and rear of the adsorption device body 3. When in use, they are used to replace and maintain the activated carbon components. The inspection plate 2 at the front of the adsorption device body 3 corresponds to the first activated carbon component 8, and the inspection plate 2 at the rear of the adsorption device body 3 corresponds to the second activated carbon component 10.

[0022] Working Principle Description: This device divides the interior of the adsorption unit 3 into two sets of air ducts via the partition component 7: the first air duct 9 and the second air duct 11. During normal operation, both the first air valve 5 and the second air valve 6 are open. When exhaust gas enters the adsorption unit 3 through the air inlet 1, it enters the first air duct 9 and the second air duct 11 respectively. After being filtered and purified by the first activated carbon component 8 and the second activated carbon component 10, it is discharged through the air outlet 4. The flow rate of the exhaust gas is detected by the flow monitoring component on the air inlet duct. If the flow rate is low, either the first air valve 5 or the second air valve 6 will open. One of the air valves 6 is closed, for example, the first air valve 5 is preset to be closed. After the first air valve 5 is closed, the first air duct 9 is sealed. At this time, the exhaust gas entering the adsorption device body 3 will only enter the second air duct 11 and be purified by the second activated carbon component 10. This will not consume the first activated carbon component 8 in the first air duct 9, making reasonable use of resources and reducing the cost of subsequent maintenance. In addition, when disassembling and replacing the activated carbon on the inspection plate 2 in the later stage, there is no need to stop the machine. You only need to close the air valve at the current position to carry out the disassembly and replacement maintenance work, which increases the practicality of this device.
