Description

Technical Field

[0001] The utility model belongs to the technical field of copper series catalyst treatment, in particular to a homogenization reduction container for copper series catalysts. Background Art

[0002] Copper-zinc catalysts are based on copper oxide, with zinc oxide, chromium oxide and aluminum oxide as promoters. The active component of copper-zinc catalysts is metallic copper microcrystals. Copper oxide has no catalytic activity for the conversion reaction. Before use, the active elemental copper must be reduced with a reducing gas to ensure that the catalyst has good activity during the working process. However, it still has the following disadvantages in actual use:

[0003] 1. When reducing a copper-based catalyst, a reducing agent is placed in a container, heated, and then a reducing gas is introduced, so that the copper oxide in the catalyst is reduced to elemental copper by the reducing agent at high temperature. However, during the reduction process, the diffusion effect of the reducing gas is limited, resulting in uneven reduction of the catalyst;

[0004] 2. The copper-based catalyst is directly contained in the reduction container during reduction, and then taken out from the container after reduction in the reduction container. However, during the taking-out process, the reaction container needs to be opened and the catalyst is directly taken out from the container. During the taking-out process, equipment needs to enter the container for operation, which is not convenient to take out the reduced copper-based catalyst in the container. Utility Model Content

The breathable disk 103 is fixed in the fixing ring 102. After the reducing gas entering the reactor 1 passes through the breathable disk 103, it is The reaction kettle 1 and the insulation sleeve 101 are homogenized and transported to the upper part thereof, so that the reduction of the copper-based catalyst is more uniform. A top cover 3 is provided at the top of the reactor 1 and the insulation sleeve 101, and the top of the reactor 1 is closed by the top cover 3. A fixing rod 403 is fixed at the center of the bottom end of the top cover 3, and the top cover 3 and the fixing frame 401 are connected together by the fixing rod 403. A fixing frame 401 is fixed to the bottom end of the fixing rod 403, and a movable sleeve 4 is fixed to the outside of the fixing frame 401. The movable sleeve 4 is connected to the fixed rod 403 through the fixing frame 401, so that when the top cover 3 is raised or lowered, the movable sleeve 4 is driven to rise or fall.

[0027] Specifically, an input pipe 104 is fixedly connected to the center of the bottom end of the reactor 1, and an electric control valve 105 is fixed on the peripheral side of the input pipe 104. The reactor 1 inputs reducing gas into the reactor 1 through the input pipe 104, and the input on and off of the input pipe 104 is controlled by the electric control valve 105.

[0028] Furthermore, a fixed ring 2 is fixed on the inner wall of the insulation sleeve 101 above the fixed ring 102, and a heating component 201 is fixed on the inner wall of the fixed ring 2. The fixed ring 2 is arranged below the movable sleeve 4, and the insulation sleeve 101 fixes the heating component 201 therein through the fixed ring 2. When the reducing gas passes through, it is heated, and the gas rises to the copper-based catalyst in the movable sleeve 4, heating the copper-based catalyst while reducing the copper-based catalyst.

[0029] The operation process of this embodiment is: after the copper-based catalyst that needs to be reduced is placed in the movable sleeve 4, and then it is set in the insulation sleeve 101 in the reactor 1, the electric control valve 105 is opened to allow the reducing gas to be input into the insulation sleeve 101, and then pass through the breathable disk 103 in the fixed ring 102, and then be evenly distributed, and transported to the heating component 201 in the fixed ring 2 2 to be heated.

After the reduction work is completed, the electric control valve 105 is closed. Specific embodiment 2

[0031] See also Figure 1 , 2, 4, 5, on the basis of the specific embodiment 1, a fixing rod 301 is fixed at the center of the top end of the top cover 3, a mounting plate 302 is fixed at the top end of the fixing rod 301, the top cover 3 is connected to the mounting plate 302 through the fixing rod 301, and is mounted on an external lifting device through the mounting plate 302, and the top cover 3 is driven to rise and fall through the lifting device.

[0032] Specifically, the top of the top cover 3 on one side of the fixing rod 301 is fixedly connected with an output pipe 303, and the side of the top of the top cover 3 away from the output pipe 303 is fixedly connected with a ventilation pipe 305. The sides of the output pipe 303 and the ventilation pipe 305 are fixed with an electric control valve 2 304. The top of the output pipe 303 is connected with a vacuum device. When the vacuum device is working, a negative pressure is generated in the reactor 1, and most of the reducing gas in the reactor 1 is extracted. The delivery on and off of the output pipe 303 is controlled by the electric control valve 2 304. After five minutes of vacuuming, the reducing gas in the insulation sleeve 101 is basically extracted, and the inside is under negative pressure. The electric control valve 2 304 on the side of the ventilation pipe 305 is opened to allow air to enter the insulation sleeve 101 in the reactor 1, so that the insulation sleeve 101 returns to normal pressure.

[0033] Furthermore, the movable sleeve 4 is sleeved in the insulation sleeve 101, and the lower part of the inner wall of the movable sleeve 4 is fixed with filter screens 402 in a circular array. All the filter screens 402 are fixed in the fixing frame 401. The movable sleeve 4 supports the copper-based catalyst to be reduced through the filter screens 402, and allows the reducing catalyst to pass through the filter screens 402 and enter the copper-based catalyst.

[0034] The operation process of this embodiment is as follows: when working, first, the top cover 3 is driven to be lifted by an external lifting device. After the top cover 3 is driven to be lifted, the top cover 3 drives the fixing frame 401 and the movable sleeve 4 to be lifted through the fixing rod 403. At this time, the copper catalyst is poured into the movable sleeve 4, and then supported by the fixing frame 401 and the filter screen 402. Then, the reducing gas is input into the movable sleeve 4 through the input pipe 104 at the bottom of the reactor 1, and is homogenized through the air permeable disk 103. After being heated by the heating component 201, the reducing gas enters the copper catalyst in the movable sleeve 4 through the filter screen 402, so that the copper catalyst is heated and reduced. After the catalyst is reduced, the reducing gas is pumped into the movable sleeve 4 by the exhaust device when it is working. Negative pressure is generated in the reactor 1, and most of the reducing gas in the reactor 1 is extracted. The delivery on and off of the output pipe 303 is controlled by the electric control valve 2 304. After five minutes of exhaust, the reducing gas in the insulation sleeve 101 is basically extracted, and the interior is under negative pressure. The electric control valve 2 304 around the ventilation pipe 305 is opened to allow air to enter the insulation sleeve 101 in the reactor 1, so that the insulation sleeve 101 returns to normal pressure. The mounting plate 302 is installed on an external lifting device, and the lifting device drives the top cover 3 to be lifted away from the insulation sleeve 101, and then the reduced copper-based catalyst can be taken out from the movable sleeve 4 to carry out the next working cycle.
