[0002] The main function of the hydrogenation reactor is to serve as a container for hydrogenation reactions and to be used in situations where liquids and gases need to be fully mixed. In the petroleum refining industry, hydrogenation reactors are often used to hydrogenate the heavy part of residual oil into light oil, thereby producing gasoline, diesel, etc. In addition, hydrogenation reactors are also widely used in chemical pharmaceuticals and can be used as basic equipment for product development, organic chemicals and pharmaceutical research. The liquid phase hydrogenation reactor distributor is a key component in the field of coal chemical equipment technology. This distributor plays a vital role in the liquid phase hydrogenation reaction process. It is mainly used to evenly distribute the reaction materials to ensure that the reaction can be carried out efficiently and evenly.

[0003] However, the existing distributor is generally fixed at the entrance of the hydrogenation reactor, so once the distributor is damaged, it is very troublesome to replace it, making it unusable, causing the working efficiency of the hydrogenation reactor to be greatly reduced. For this reason, we propose a distributor for a liquid phase hydrogenation reactor. Utility Model Content

[0028] The inner wall of the hydrogenation reactor 1 is provided with a clamping device for facilitating the disassembly of the distributor body 3;

[0029] A filter device for filtering impurities from the hydrogenation liquid is arranged inside the distributor body 3 .

[0030] Furthermore, a locking groove 8 is provided on the side of the distributor body 3, and two limiting grooves are provided on the top of the distributor body 3, and three connecting rods 11 are fixedly connected to the bottom of the distributor body 3. The three connecting rods 11 are arranged in a triangle at the bottom of the distributor body 3, and a speed reduction plate 12 is connected to the bottom of the three connecting rods 11.

[0031] Furthermore, the top of the speed reduction plate 12 is cone-shaped, and the center point of the cone at the top of the speed reduction plate 12 is located below the center point of the bottom of the distributor body 3, and the slope of the top of the speed reduction plate 12 is thirty degrees.

[0032] Furthermore, the clamping device includes an arc groove 4, a connecting column 5, a locking plate 6 and a spring 7. The inner wall of the top opening of the hydrogenation reactor 1 is provided with an arc groove 4, and two connecting columns 5 are movably connected inside the arc groove 4. The side surfaces of the two connecting columns 5 are respectively fixedly connected with a locking plate 6, and the middle ends of the two locking plates 6 are respectively fixedly connected with a spring 7.

[0033] Furthermore, the two locking pieces 6 are both bent, and one end of two springs 7 is fixedly connected to the bending points of the two locking pieces 6, and the other ends of the two springs 7 are fixedly connected to the inner wall of the top opening of the hydrogenation reactor 1, and the movable ends of the two locking pieces 6 are movably connected to the inside of the locking groove 8.

[0034] Furthermore, the filter device includes a filter 9 and a fixing block 10 . The filter 9 is movably connected inside the dispenser body 3 , and the top of the filter 9 is fixedly connected to two fixing blocks 10 .

[0035] Furthermore, the filter screen 9 is cylindrical, and circular holes are provided at the bottom and sides of the filter screen 9 , and one end of the two fixing blocks 10 is movably connected to the inside of two limiting grooves provided at the top of the distributor body 3 .

[0036] Working principle: When the device is needed, the hydrogenation liquid will first enter the interior of the hydrogenation reactor 1 through the feed connecting pipe 2. When the hydrogenation liquid enters the interior of the hydrogenation reactor 1, it will pass through the distributor body 3 at the top of the hydrogenation reactor 1 and the filter screen 9 inside the distributor body 3, thereby filtering the impurities in the hydrogenation liquid to prevent excessive impurities in the hydrogenation liquid from affecting the subsequent catalytic reaction. Then the hydrogenation liquid flows along the distributor body 3 to the deceleration disk 12, and hits the top of the deceleration disk 12, thereby slowing down the impact force of the flow of the hydrogenation liquid, so that the hydrogenation liquid can flow along the ramp on the top of the deceleration disk 12 to the distribution disk inside the hydrogenation reactor 1, thereby preventing the hydrogenation liquid flow rate from being too high and destroying the distribution disk inside the hydrogenation reactor 1.

[0037] When the distributor body 3 needs to be replaced, the feed connecting pipe 2 is first opened, and then the distributor body 3 is rotated so that the two locking pieces 6 can squeeze the two springs 7 so that one end of the two locking pieces 6 slides out of the locking groove 8 close to the surface of the distributor body 3, so that the distributor body 3 can be pulled out from the top end of the hydrogenation reactor 1. Conversely, the new distributor body 3 is placed into the top end of the hydrogenation reactor 1, and then the distributor body 3 is rotated, so that the elastic force of the two springs 7 is utilized to make the two locking pieces 6 respectively drive the connecting rod 11 fixedly connected at one end thereof to rotate, so that one end of the two locking pieces 6 is engaged with the inside of the locking groove 8, so that the distributor body 3 can be fixed at the top end of the hydrogenation reactor 1, thereby completing the replacement of the distributor body 3.
