Description

Technical Field

[0001] This utility model relates to the technical field of waste gas purification and treatment equipment, specifically a waste gas treatment equipment for regenerated activated carbon. Background Technology

[0002] In the industrial production sector, waste gas treatment is a key link in ensuring environmental quality and production sustainability. Traditional waste gas treatment equipment widely uses activated carbon adsorption to purify waste gas. Activated carbon, with its rich pore structure and huge specific surface area, can effectively adsorb harmful substances in waste gas, thereby achieving the purpose of purifying waste gas.

[0003] In traditional waste gas treatment equipment, activated carbon is a commonly used adsorbent material, widely used to remove harmful substances from waste gas. However, these devices require shutdown when replacing activated carbon, which brings a series of drawbacks. First, shutdown means the interruption of waste gas treatment. In some enterprises with strict requirements for waste gas emissions and where production cannot be stopped for extended periods, this can lead to waste gas not being treated in a timely manner, thus affecting normal production. Second, during shutdown, enterprises not only cannot carry out normal production activities, resulting in a loss of production efficiency, but also need to invest additional manpower and time costs in replacing activated carbon. Furthermore, frequent shutdowns and restarts of the equipment can also adversely affect the service life of the equipment itself, increasing the cost of equipment maintenance and replacement. To solve the above problems, we propose a regenerated activated carbon waste gas treatment device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a regenerated activated carbon waste gas treatment device, which solves the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a regenerated activated carbon waste gas treatment device, comprising an inlet pipe, an outlet pipe, a first purification cylinder, and a second purification cylinder. The bottom end of the inlet pipe is provided with a branched pipe, and the other end of the branched pipe is respectively fixedly installed with the first purification cylinder and the second purification cylinder.

The device also includes:

[0006] The switching device, through the meshing transmission between the fixed rack and gear, and the gear and the moving rack, realizes the conversion of the motor's rotary motion to the linear motion of the moving rack, which enables the control of the opening and closing of the first and second purification cylinder sealing doors, thereby quickly replacing the regenerated activated carbon.

[0007] Preferably, the first and second purification cylinders each have an opening on the opposite side, and the openings are respectively provided with a first purification cylinder door and a second purification cylinder door. Two sets of exhaust gas detection sensors are fixedly installed on the top and bottom sides of the first and second purification cylinders respectively.

[0008] Preferably, both the first and second purification cylinders have two sets of sealing grooves inside. The sealing door of the first and second purification cylinders are fixedly installed with sealing gaskets of the same size corresponding to the openings of the first and second purification cylinders. The sealing gaskets are arc-shaped. Two sets of sealing rings are fixedly installed on the sealing gaskets. The size of the two sets of sealing rings corresponds to the sealing grooves. Regenerated activated carbon is slidably engaged in the middle of the two sets of sealing rings.

[0013] Compared with the prior art, this utility model provides a regenerated activated carbon waste gas treatment device, which has the following beneficial effects:

[0014] 1. This regenerated activated carbon waste gas treatment equipment addresses the common problem that traditional waste gas treatment equipment often requires shutdown for activated carbon replacement. This not only affects the continuous operation of the equipment but also increases maintenance costs and time. This device, through a switching device, enables rapid replacement of regenerated activated carbon without shutting down the system. When the waste gas detection sensor detects that the treatment effect is not ideal, the system automatically closes the valve of the corresponding purification cylinder and activates the switching device to open the sealing door, allowing operators to quickly replace the activated carbon. This improves the operating efficiency and availability of the equipment and reduces production losses caused by downtime for maintenance. Attached Figure Description

The other end of the rotating rod 20 is hinged to the connecting rod 19. The other end of the connecting rod 19 is hinged to the gear 18. The switching device 9 is driven by the motor 21, and the power is transmitted to the gear 18 through the rotating rod 20 and the connecting rod 19, thereby driving the moving rack 17 to move. This ensures the accurate operation of the switching device 9 and improves the automation level and operating efficiency of the equipment.

[0030] Furthermore, a fixed arm 22 is fixedly installed at one end of the movable rack 17.

[0053] Instructions for use

[0054] Exhaust gas enters the equipment through inlet pipe 1, and is introduced into the first purification cylinder 3 and the second purification cylinder 4 through the branch pipes at the bottom. In these two purification cylinders, regenerated activated carbon adsorbs and purifies the exhaust gas. The purified gas converges through the branch pipes at the other end of the purification cylinders and is finally discharged from the equipment through outlet pipe 2. Each of the multiple branch pipes in the equipment is equipped with an electric valve 5, driven by a valve motor 10, which controls the flow of gas in each pipe. When the exhaust gas detection sensors 11 at the top and bottom of the first purification cylinder 3 or the second purification cylinder 4 detect that the exhaust gas treatment effect in a certain purification cylinder is not ideal, a signal will be sent. Upon receiving the signal, the system will close the two sets of electric valves 5 in the corresponding purification cylinder's branch pipe, thereby blocking the airflow in that purification cylinder. Then, the switching device 9 is activated. The switching device 9 is driven by motor 21, and the motor output shaft drives the rotating rod 20 to rotate. The rotating rod 20 drives the gear 18 to slide in the groove of the mounting plate 15 through the connecting rod 19. Since the fixed rack 16 meshes with the gear 18, and the gear 18 also meshes with the moving... The rack 17 engages, thus converting the rotational motion of the motor 21 into the linear motion of the moving rack 17. The fixed arm 22, which is fixed at one end of the moving rack 17, is connected to the first purification cylinder sealing door 6 or the second purification cylinder sealing door 7. Therefore, the linear motion of the moving rack 17 will drive the sealing door to open. The regenerated activated carbon slides and engages with the sealing ring 14 in the middle of the sealing gasket 13. As the sealing door opens, the regenerated activated carbon can be taken out from the purification cylinder for easy replacement by the operator. The sealing groove 12 inside the first purification cylinder 3 and the second purification cylinder 4 cooperates with the sealing gasket 13 and the sealing ring 14 to form a sealing system, ensuring that the exhaust gas will not leak during the operation of the equipment. After the replacement is completed, the sealing door is closed and the previously closed electric valve 5 is opened, and the equipment can continue to operate normally. This achieves rapid replacement of regenerated activated carbon without stopping the machine, ensuring that the equipment can continuously and efficiently treat exhaust gas.
