Description

Technical Field

[0001] The utility model belongs to the technical field of organic synthesis catalytic hydrogenation process, and particularly relates to a hydrogenation catalyst activation device. Background Art

[0002] The catalytic hydrogenation technology for organic synthesis originated from the coal direct liquefaction technology developed and industrially applied in Germany in the 1920s and 1930s. It has developed to include hydrofining, hydrotreating, hydrocracking, etc. Through the hydrogenation process, not only can the product quality be improved, but also the product variety can be greatly enriched, the chemical industry chain can be extended, and the economic benefits of chemical companies can be significantly improved. It has been widely used in modern refining and fine chemical industries. Hydrogenation catalysts are the core of hydrogenation technology, and their development and application have received attention in this field. Hydrogenation catalysts are mostly solid catalysts containing metal components or their compounds, which are composed of active metal components, carriers, and a small amount of additives. Under normal circumstances, in order to maintain the stability of the properties of the hydrogenation catalyst, the hydrogenation catalyst is in an inactive state before loading and use, and needs to be activated to make it have hydrogenation activity.

[0003] The effect of hydrogenation catalyst activation has a great influence on its hydrogenation activity. In order to obtain a catalyst with high hydrogenation activity, the hydrogenation catalyst must be fully activated and the good structure of the hydrogenation catalytic active components must be maintained. The existing technology has the following problems: most activation devices are static, with a relatively smooth cylindrical interior. During use, the catalyst is prone to static accumulation in a certain part, resulting in uneven heating and insufficient contact with the activation atmosphere, which can easily lead to insufficient activation of the hydrogenation catalyst, or partial sintering of the active components, structural damage, reduced activity, or even inactivation.

[0004] In addition, there are certain risks in the process of hydrogenation catalyst activation, which may cause personal injury. Traditional activation devices require frequent close-range operation of the equipment, which inevitably exposes people to dangerous environments. Utility Model Content

[0005] In order to effectively solve the above technical problems, the utility model aims to provide a hydrogenation catalyst activation device.

[0006] The purpose of the utility model is achieved as follows: a hydrogenation catalyst activation device, including a supporting frame, characterized in that a rotatable activation furnace is installed on the supporting frame and a gear transmission is provided, and a material distribution structure for dispersing materials to avoid accumulation of hydrogenation catalysts is provided in the activation furnace; both ends of the activation furnace are movably connected with inlet and outlet pipes and tail gas outlet pipes; a remote control cabinet is configured to remotely control the activation furnace by wired or wireless means.

[0007] The purpose of the utility model can also be achieved in this way: the material distribution structure is a spiral push-type material distribution structure, which is a thread-shaped protrusion integrally formed in the activation furnace body.

[0008] The gear transmission device is equipped with a rotatable transmission gear inside, and the transmission gear is meshed with a driven gear integrally formed on the activation furnace, thereby driving the activation furnace to rotate. The gear transmission device is remotely controlled by a remote control cabinet.

[0009] The two ends of the activation furnace are respectively connected to the inlet and outlet pipes and the tail gas outlet pipe through slip-on flanges, and the inlet and outlet pipes and the tail gas outlet pipe are supported and fixed to the support frame by fixing rods.

[0010] A hydraulic lifting rod is arranged inside the supporting frame, and the hydraulic lifting rod is connected to the rear end of the activation furnace.

[0011] The inlet and outlet pipelines are provided with a catalyst raw material inlet, a catalyst finished product outlet and an air inlet.

[0012] The remote control cabinet is provided with a temperature meter, a voltage meter and a control panel.

[0013] The utility model has the following beneficial effects.

[0014] 1. The spiral push-type material distribution structure inside the activation furnace. This structural design, in conjunction with the rotating activation furnace, enables the hydrogenation catalyst to move inside the activation furnace and be evenly distributed, thereby dispersing the material, avoiding the accumulation of hydrogenation catalysts, and fully activating the catalyst.

[0015] 2. A gear transmission is installed between the activation furnace and the support frame. The activation furnace is connected to the inlet and outlet pipes and the exhaust gas outlet pipe through a slip-on flange. A fixing rod is welded between the inlet and outlet pipes, the exhaust gas outlet pipe and the support frame, so that the activation furnace can rotate while the inlet and outlet pipes and the exhaust gas outlet pipe are fixed.

[0016] 3. There are multiple air inlets on the inlet and outlet pipes, which can be used to introduce a variety of gases to meet the needs of different activation conditions.

[0017] 4. The gear transmission can drive the activation furnace to rotate. During activation, when the activation furnace rotates clockwise, the spiral push-type distribution structure can make the catalyst evenly distributed; during unloading, the activation furnace rotates counterclockwise, and the spiral push-type distribution structure can improve the unloading efficiency.

[0018] 5. A hydraulic lifting rod is installed between the activation furnace and the supporting frame. When unloading, the rear end of the activation furnace can be lifted to increase the unloading slope. A remote control cabinet is used to control the activation furnace, hydraulic lifting rod, and gear transmission, which significantly reduces close contact between personnel and equipment and reduces potential risks.

DETAILED DESCRIPTION

[0025] The following will describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present utility model.

[0026] See attached Figure 1-4 As shown, a hydrogenation catalyst activation device is composed of an activation furnace 1, an inlet and outlet pipe 2, a support frame 3, a gear driver 4, an exhaust gas outlet pipe 5, and a remote control cabinet 6. The activation furnace 1 is composed of a furnace body 10, a spiral push-type material distribution structure 11, and a slip-on flange 12. The gear driver 4 is installed between the activation furnace 1 and the support frame 3, and both ends of the activation furnace 1 are connected to the inlet and outlet pipe 2 and the exhaust gas outlet pipe 5 by slip-on flanges 12, and a fixing rod 32 is welded between the inlet and outlet pipe 2 and the exhaust gas outlet pipe 5 and the support frame 3.

[0027] The inlet and outlet pipes are composed of a pipe body 20, a catalyst raw material feed port 21, a catalyst finished product discharge port 22 and an air inlet 23. The catalyst raw material is loaded into the furnace body 10 of the activation furnace through the catalyst raw material feed port 21, and the temperature of the activation furnace 1, the rotation direction and speed of the transmission gear 41 in the gear transmission 4 are controlled by the remote control cabinet 6. The gear transmission 4 drives the furnace body 10 of the activation furnace 1 to rotate, while the inlet and outlet pipes 2 and the tail gas outlet pipe 5 are fixed, and the required gas is introduced from the air inlet 23. After the activation is completed, the hydraulic lifting rod 31 is controlled to be lifted by the remote control cabinet 6, and the rotation direction and speed of the transmission gear 41 in the gear transmission 4 are changed, and the valve on the catalyst finished product discharge port 22 is opened to complete the unloading.

[0028] Furthermore, the inlet and outlet pipes are provided with a plurality of gas inlets 23. One or more gases can be introduced into the gas inlets 23 according to the activation working conditions.

[0029] Furthermore, there is a spiral push-type material distribution structure 11 inside the activation furnace 1. When the activation furnace 1 rotates clockwise, the spiral push-type material distribution structure 11 completes the feeding and makes the catalyst evenly distributed. When the furnace body 10 of the activation furnace rotates counterclockwise, the spiral push-type material distribution structure 11 can assist in unloading.

[0030] Furthermore, the support frame 3 is equipped with a hydraulic lifting rod 31. The hydraulic lifting rod 31 is connected to the rear end of the activation furnace 1. When unloading, the hydraulic lifting rod 31 lifts the rear end of the activation furnace 1, so that the catalyst moves to the catalyst finished product discharge port 22 under the action of gravity, thereby improving the unloading efficiency.

[0031] The activation furnace 1, hydraulic lifting rod 31, and gear transmission 4 are all controlled by a remote control cabinet 6. The remote control cabinet 6 has a temperature meter 61, a voltage meter 62, and a control panel 63. Many operations in the activation work are completed through the remote control cabinet 6, reducing the risks caused by close operation of personnel.

[0032] The utility model has the following characteristics.

[0033] 1. A gear transmission is installed between the activation furnace and the support frame. The activation furnace is connected to the inlet and outlet pipes and the exhaust gas outlet pipe through a slip-on flange. A fixing rod is welded between the inlet and outlet pipes and the exhaust gas outlet pipe and the support frame, so that the activation furnace can rotate while the inlet and outlet pipes and the exhaust gas outlet pipe are fixed. Furthermore, a spiral push-type distribution structure is designed inside the activation furnace, which can make the hydrogenation catalyst evenly dispersed and move inside the activation device, so that the hydrogenation catalyst can be prevented from accumulating, fully activated, and the activation efficiency can be improved.

[0034] 2. There are multiple air inlets on the inlet and outlet pipes, which can be used to introduce one or more gases to meet various activation conditions; a hydraulic lifting rod is installed between the activation furnace and the supporting frame to assist in unloading.

[0035] 3. Use a remote control cabinet to operate the activation furnace, hydraulic lifting rod, and gear transmission, significantly reducing close contact between personnel and equipment and reducing potential risks.
