Description

Technical Field

[0001] This utility model relates to the field of steam condensation recovery technology, specifically a steam condensation recovery waste gas treatment device. Background Technology

[0002] Activated carbon is widely used in waste gas treatment because of its excellent adsorption effect. After a certain period of adsorption, the activated carbon needs to be desorbed by high-temperature steam. The desorbed activated carbon can be put back into the gas adsorption operation, while the desorbed organic matter is condensed and recovered. It can condense various waste gases, including ethanol.

[0003] Patent CN215388572U discloses a steam desorption condensation recovery waste gas treatment device, including an activated carbon treatment chamber. One end of the activated carbon treatment chamber is configured as an air inlet pipe, and the other end is configured as an exhaust pipe. A steam inlet is located at the top of the activated carbon treatment chamber, and a waste outlet is located at the bottom. Inside the activated carbon treatment chamber, rollers are located near both ends, and a belt connects two of the rollers. At least four perforated push plates are installed on the outer surface of the belt. This invention incorporates rotating perforated push plates inside the activated carbon treatment chamber. Repeated rotation continuously changes the position of the activated carbon within the chamber, ensuring that all activated carbon reaches the same adsorption saturation rate, extending the desorption cycle, and preventing waste. During the desorption stage, each portion of activated carbon can repeatedly contact the steam that just enters the activated carbon treatment chamber, resulting in excellent desorption performance.

[0004] The aforementioned patent has the following problems:

[0005] After a period of use, the mesh screens become clogged with activated carbon, which affects the efficiency of waste gas recovery. Furthermore, it is not convenient to quickly remove multiple mesh screens for cleaning, and the conveyor belt structure is relatively complex, increasing production costs. Therefore, we have introduced a steam condensation waste gas recovery treatment device. Utility Model Content

[0006] The purpose of this invention is to provide a steam condensation recovery waste gas treatment device that facilitates quick cleaning of multiple filter screens by staff, ensuring the effectiveness of the filter screens and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A steam condensation recovery waste gas treatment device includes a circular shell. A motor is fixedly installed in the middle of the side wall of the circular shell. A rotating shaft is rotatably installed in the center of the interior of the circular shell via a rolling bearing. The output end of the motor passes through the interior of the circular shell and is fixedly connected to the rotating shaft. Multiple mesh push plates are fixedly installed on the shaft wall. The side of the mesh push plate away from the rotating shaft is slidably connected to the inner side of the circular shell. An air inlet pipe and an exhaust pipe are respectively provided on both sides of the circular shell. A steam inlet and a waste outlet are provided at the upper end of the circular shell. Filter screens are provided in the air inlet pipe, exhaust pipe, steam inlet, and waste outlet. A linkage mechanism is provided between the multiple filter screens.

[0009] As a further embodiment of this utility model, the linkage mechanism includes an electric push rod, which is fixedly disposed at the center of the side wall of the circular housing. A push plate is fixedly disposed at the output end of the electric push rod. A connecting plate is fixedly disposed at the edge of the push plate at a position corresponding to the position of multiple filter screens. The side walls of the air inlet pipe, exhaust pipe, steam inlet and waste outlet are provided with strip-shaped holes that cooperate with the connecting plates. One side of the connecting plate passes through the strip-shaped hole and is fixedly connected to the corresponding filter screen.

[0010] As a further embodiment of this invention, the push plate is configured in a cross shape.

[0011] As a further embodiment of this invention, the filter screen is configured as a stainless steel mesh.

[0012] As a further embodiment of this utility model, a sealing ring is fixedly provided on the wall of the strip hole, and the inner side of the sealing ring is slidably connected to the connecting plate.

[0013] As a further embodiment of this invention, the sealing ring is configured as a corrosion-resistant rubber ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This steam condensation recovery waste gas treatment device, equipped with a pusher plate, connecting plate, sealing ring, steam inlet, circular shell, filter screen, air inlet pipe, waste outlet, electric push rod, exhaust pipe, motor, mesh push plate, and rotating shaft, feeds waste gas into the air inlet pipe. The organic matter in the waste gas can be adsorbed by activated carbon. At the same time, the motor is started, and the motor drives the mesh push plate to rotate through the rotating shaft, which in turn pushes the activated carbon to move inside the circular shell. Repeated rotation continuously changes the position of the activated carbon inside the circular shell, ensuring that the adsorption saturation rate of all activated carbon is equal. The adsorbed clean air is discharged through the exhaust pipe. When multiple filter screens need to be cleaned, the electric push rod is pushed, and the electric push rod pushes the push plate. The push plate, through the connecting plate, moves multiple filter screens to the outside of the air inlet pipe, exhaust pipe, steam inlet, and waste outlet, making it convenient for staff to quickly clean multiple filter screens and ensuring the effectiveness of the filter screens.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution:

[0022] A steam condensation recovery waste gas treatment device includes a circular shell 5, with activated carbon inside the circular shell 5. A motor 11 is fixedly installed in the middle of the side wall of the circular shell 5. The motor 11 is electrically connected to an external power source via a control switch. A rotating shaft 13 is rotatably installed in the center of the circular shell 5 via a rolling bearing. The output end of the motor 11 passes through the circular shell 5 and is fixedly connected to the rotating shaft 13. Multiple mesh push plates 12 are fixedly installed on the shaft wall of the rotating shaft 13. The side of the mesh push plate 12 away from the rotating shaft 13 is slidably connected to the inner side of the circular shell 5. An air inlet pipe 7 and an exhaust pipe 10 are respectively provided on both sides of the circular shell 5. A steam inlet 4 and a waste outlet 8 are provided at the upper end of the circular shell 5. Filter plates 6 are installed in the air inlet pipe 7, the exhaust pipe 10, the steam inlet 4, and the waste outlet 8. A linkage mechanism is provided between the multiple filter plates 6.

[0023] The linkage mechanism includes an electric push rod 9, which is fixedly installed at the center of the side wall of the circular housing 5. A push plate 1 is fixedly installed at the output end of the electric push rod 9. A connecting plate 2 is fixedly installed at the edge of the push plate 1 at the corresponding positions of multiple filter screens 6. The side walls of the air inlet pipe 7, exhaust pipe 10, steam inlet 4, and waste outlet 8 are provided with strip-shaped holes that cooperate with the connecting plate 2. One side of the connecting plate 2 passes through the strip-shaped hole and is fixedly connected to the corresponding filter screen 6. The push plate 1 is set in a cross shape, and the filter screen 6 is made of stainless steel metal mesh, which improves the service life.

[0024] Reference Figure 1 The wall of the strip hole is fixedly provided with a sealing ring 3, and the inner side of the sealing ring 3 is slidably connected to the connecting plate 2. The sealing ring 3 is made of corrosion-resistant rubber ring, which is not easy to corrode and has a long service life.

[0025] During use, exhaust gas is fed in through the inlet pipe 7. The organic matter in the exhaust gas can be adsorbed by activated carbon. At the same time, the motor 11 is started. The motor 11 drives the mesh push plate 12 to rotate through the rotating shaft 13, which in turn pushes the activated carbon to move inside the circular shell 5. Repeated rotation can continuously change the position of the activated carbon inside the circular shell 5, ensuring that the adsorption saturation rate of all activated carbon is equal. The adsorbed clean air is discharged through the exhaust pipe 10. When multiple filter plates 6 need to be cleaned, the electric push rod 9 is pushed. The electric push rod 9 pushes the push plate 1. The push plate 1 drives multiple filter plates 6 to move to the outside of the inlet pipe 7, exhaust pipe 10, steam inlet 4 and exhaust port 8 through the connecting plate 2, which facilitates the staff to clean multiple filter plates 6 quickly and ensures the use effect of filter plates 6.
