The main purpose of this work is to reduce environmental pollution, improve gas quality, prevent sulfides from corroding subsequent equipment, and ensure that the gas meets emission standards or subsequent utilization requirements.

[0003] In traditional desulfurization work, desulfurizing agents are often manually added to the catalyst. However, since the entire desulfurization process requires multiple desulfurizing agent additions, and the amount of desulfurizing agent added each time varies, workers need to use measuring equipment to accurately measure the amount of desulfurizing agent added to avoid deviations. This method requires workers to spend a lot of time, which affects the efficiency of the desulfurization work.

[0004] Therefore, it is necessary to design a catalyst feeding device for coke oven gas desulfurization. SUMMARY

[0007] As a further preferred scheme, a motor is installed on one side of the mixing cylinder, and a stirring rod is rotatably connected inside the mixing cylinder. One end of the stirring rod passes through the mixing cylinder and is connected to the output shaft of the motor.

[0021] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Example: A catalyst feeding device for desulfurization of coke oven gas, such as... Figures 1-5 As shown, the system includes a mixing cylinder 1, a funnel 2, a conveying pipe 3, a first sealing plate 5, a second sealing plate 7, a connecting plate 701, and cylinders 702. The funnel 2 is fixedly connected to the top of the mixing cylinder 1, and the conveying pipe 3 is fixedly connected to the bottom of the funnel 2. The conveying pipe 3 is interconnected with the mixing cylinder 1. The first sealing plate 5 is slidably connected to the mixing cylinder 1 near the conveying pipe 3. Multiple cylinders 702 are evenly spaced on the top of the conveying pipe 3. The piston rod of each cylinder 702 is fixedly connected to the second sealing plate 7, and a connecting plate 701 is fixedly connected to one side of the second sealing plate 7. Both the sealing plate 7 and the connecting plate 701 movably penetrate the conveying pipe 3. Here, the connecting plate 701 has a circular through hole. When the connecting plate 701 extends into the conveying pipe 3, the conveying pipe 3 is unobstructed. When the cylinder 702 is activated, the piston rod of the cylinder 702 retracts inward. The piston rod of the cylinder 702 drives the connected second sealing plate 7 to move inward. The second sealing plate 7 drives the connecting plate 701 to move inward, so that the connecting plate 701 exits the conveying pipe 3. After the second sealing plate 7 enters the conveying pipe 3, it divides the conveying pipe 3 into multiple columns of equal capacity.

[0023] like Figure 2 As shown, a motor 4 is installed on one side of the mixing cylinder 1. A stirring rod 401 is rotatably connected inside the mixing cylinder 1. One end of the stirring rod 401 passes through the mixing cylinder 1 and is connected to the output shaft of the motor 4. Here, when the motor 4 is started, the motor 4 drives the output shaft to rotate. The output shaft of the motor 4 drives the connected stirring rod 401 to rotate, thereby causing the stirring rod 401 to stir the desulfurizing agent raw materials inside the mixing cylinder 1, so that the desulfurizing agent raw materials are fully mixed, realizing the preparation of desulfurizing agent, and improving the working efficiency and working quality of the device.

[0024] like Figure 3 As shown, a fixed frame 6 is fixedly connected to the end of the conveying pipe 3 away from the mixing cylinder 1. A first guide rod 602 is fixedly connected to the top of the fixed frame 6. A switch plate 601 is slidably connected to the first guide rod 602. The switch plate 601 is movably connected to the fixed frame 6. Here, the switch plate 601 is slid outward to slide out of the fixed frame 6, thereby releasing the blocking effect of the switch plate 601 on the conveying pipe 3, allowing the desulfurizing agent in the conveying pipe 3 to flow outward.

[0025] like Figure 5As shown, the conveying pipe 3 is fixedly connected with a second guide rod 703 on one side, and the second guide rod 703 is slidably connected with the communication plate 701. Here, the second guide rod 703 is designed to provide guidance for the movement of the second sealing plate 7 and the communication plate 701, so as to prevent the second sealing plate 7 and the communication plate 701 from deviating during movement, and ensure that the second sealing plate 7 and the communication plate 701 are tightly connected with the conveying pipe 3.

[0026] As shown, Figure 1 As shown, the bottom of the mixing cylinder 1 is fixedly connected with a collection frame 8, and the collection frame 8 is located below the conveying pipe 3. Here, the collection frame 8 is designed to collect the desulfurizing agent carried by the communication plate 701 when it moves outward, so as to prevent the desulfurizing agent from leaking and polluting the working environment, and to recycle the collected desulfurizing agent, which is conducive to reducing resource waste and improving utilization.

[0027] The device is used for continuously adding desulfurizing agent to a catalytic converter for coke oven gas desulfurization. When in use, a proper amount of desulfurizing agent raw material is added into the mixing cylinder 1 through the hopper 2, and then the motor 4 is started. The motor 4 drives the output shaft to rotate, and the output shaft of the motor 4 drives the connected stirring rod 401 to rotate, so that the stirring rod 401 stirs the desulfurizing agent raw material in the mixing cylinder 1, and a desulfurizing agent finished product is prepared. After completion, the first sealing plate 5 is pulled outward, so that the first sealing plate 5 no longer blocks the discharge port of the mixing cylinder 1, thereby connecting the mixing cylinder 1 with the conveying pipe 3. The desulfurizing agent in the mixing cylinder 1 flows downward under the action of its own gravity, so that the desulfurizing agent flows into the conveying pipe 3, and is blocked by the switch plate 601 at the end of the conveying pipe 3 away from the mixing cylinder 1. Then the air cylinder 702 is started, the piston rod of the air cylinder 702 is retracted inward, the piston rod of the air cylinder 702 drives the connected second sealing plate 7 to move inward, the second sealing plate 7 drives the communication plate 701 to move inward, so that the communication plate 701 exits the conveying pipe 3, and the second sealing plate 7 divides the conveying pipe 3 into a plurality of cylinders with equal capacity, and divides the desulfurizing agent in the conveying pipe 3 into a plurality of parts with equal mass. After completion, the switch plate 601 and the air cylinder 702 can be slid according to the feeding requirements. According to the different amounts and sequences of the desulfurizing agent, the air cylinder 702 is gradually started, so that the piston rod of the air cylinder 702 drives the corresponding second sealing plate 7 to move outward, so that the second sealing plate 7 drives the corresponding communication plate 701 to re-enter the conveying pipe 3, forming a passage for the desulfurizing agent to flow out, so that the desulfurizing agent in the corresponding cylinder is added to the catalytic converter. In this way, the effect of precise feeding and quantitative feeding is realized, and the working efficiency is ensured.
