Description

Technical Field

[0001] The utility model relates to the technical field of catalyst treatment, in particular to a desulfurization device applicable to catalysts. Background Art

[0002] The chemical raw material gas produced from natural gas, petroleum and other raw materials contains H2S gas with different concentrations. The existence of high-concentration H2S not only pollutes the environment, corrodes equipment pipelines, affects the quality of chemical products, but also causes catalyst poisoning and inactivation in subsequent process production. At present, the adsorption of sulfur on the catalyst will inevitably affect its reaction performance. After the catalyst is used for a certain period of time, it needs to be desulfurized. During the catalyst cleaning process, the surface of the catalyst can be desulfurized. Catalyst cleaning includes heating cleaning, water-gas cleaning, high-pressure water flushing, ultrasonic cleaning, rotary disturbance cleaning, etc.

[0003] The patent document with the application number CN202220277264.1 and the name "A Desulfurization Device for a Continuous Reforming Catalyst" discloses a device for desulfurizing a catalyst after it has been used for a certain period of time. When in use, first pour the catalyst into the inside of the feeding funnel, and then hold the control valve. When a force is applied, the control valve rotates, thereby opening the control valve. Under the action of its own gravity, the catalyst moves from the inside of the feeding funnel to the inside of the connecting pipe, and continues to move. The catalyst moves from the connecting pipe to the inside of the weighing box. Under the action of the gravity of the catalyst on the moving plate, the moving plate moves vertically downward in the direction close to the spring, and the spring is compressed under the force, and the spring is in a compressed state. The moving column moves vertically downward in the direction of the moving plate, and the moving column fits with the fixed column, and the moving plate stops moving. The catalyst continues to move, the catalyst moves from the moving plate to the bottom of the weighing box, and continues to move. The catalyst moves out of the inside of the weighing box, and the catalyst moves from the inside of the weighing box to the inside of the housing. Then press the button on one side of the motor. Through the button, the motor is electrically connected to the power supply. After the motor is powered on, the motor rotates under the force, and the stirring rod rotates in the direction of the motor. After the catalyst is stirred, the catalyst flows out from the inside of the discharge pipe. This device desulfurizes according to the weight of the catalyst, and uses the stirring rod to rotate in the direction of the motor to facilitate uniform stirring of the catalyst solution. However, most of the catalysts for flue gas treatment are solid catalysts. This device is convenient for desulfurizing solid catalysts. At the same time, solid catalysts are easily crushed during the process of being stirred and cleaned.
