Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a catalyst quantitative device for pre-hydrogenation and dechlorination. Background Art

[0002] Crude oil generally does not contain chlorides, so dechlorination is generally not considered in oil refining technology. However, in recent years, oil fields have adopted chemical treatment methods to improve recovery, some of which use chlorides, resulting in an increase in the chlorine content in crude oil. Most of this chlorine in crude oil is concentrated in the naphtha fraction, thus causing an increase in the chlorine content in naphtha. Chlorides in naphtha are mainly organic chlorides, such as chloroalkanes, chloroform, 1,2-dichloroethane, 1,1-dichloroethane, trichloroethane, etc.

[0003] Therefore, in the process of dechlorination, in order to increase the reaction rate and splitting rate, it is usually necessary to add a certain amount of catalyst to speed up its own reaction rate. However, the existing catalyst adding equipment does not have the function of quantitative addition, so it is impossible to accurately control the amount of catalyst added, which leads to uneven reaction rate and catalyst waste. In view of this, a catalyst quantitative device for pre-hydrogenation dechlorination is proposed to solve the above problems. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art, and provides a catalyst quantitative device for pre-hydrogenation dechlorination, which can solve the problem that in order to improve its reaction speed and splitting speed, a certain amount of catalyst is usually required to be added to accelerate its own reaction speed, but the existing catalyst adding equipment does not have the function of quantitative addition, so it is impossible to accurately control the amount of catalyst added, thereby causing the phenomenon of uneven reaction speed and catalyst waste.

[0005] To achieve the above object, the utility model provides the following technical solution: a catalyst quantitative device for pre-hydrogenation dechlorination, comprising a reactor, a feed pipe and a discharge pipe are arranged on the reactor, the feed pipe and the discharge pipe are respectively fixedly connected with connecting flanges, the reactor is fixedly connected with a catalyst storage device, and the catalyst storage device is provided with an addition hole;

[0006] The bottom of the reactor is fixedly connected with a motor, the interior of the reactor is rotatably connected with a stirring shaft, and the output end of the motor is fixedly connected with the stirring shaft;

[0007] The quantitative mechanism is arranged inside the reactor. Through the quantitative mechanism, the catalyst can be added in a fixed amount, and manual addition is no longer required, thereby ensuring that the added amount is more accurate and reducing unnecessary cumbersome steps.

[0008] Preferably, the quantitative mechanism comprises a quantitative discharge pipe, which is fixedly connected to the inside of the reactor and is interconnected with the catalyst storage device;

[0009] The quantitative discharging pipe is internally slidably connected with an I-shaped sealing rod;

[0010] A support rod is fixedly connected to the inner wall of the reactor, and a spring is provided on a movable sleeve of the support rod;

[0011] The lower end of the sealing rod is fixedly connected with a force-bearing connecting plate, and the force-bearing connecting plate is slidably connected with the supporting rod;

[0012] The two ends of the spring are respectively fixedly connected to the force-bearing connecting plate and the supporting rod.

[0013] Preferably, a stress-bearing pulling block is fixedly connected to the bottom of the stress-bearing connecting plate, and a sliding groove is provided on one side of the stress-bearing pulling block;

[0014] An auxiliary groove is provided inside the slide groove, an auxiliary sliding block is slidably connected inside the auxiliary groove, a baffle is fixedly connected to the auxiliary sliding block, and the baffle is slidably connected inside the slide groove;

[0015] A connecting rod is fixedly connected to the stirring shaft, and a pushing ball is fixedly connected to one end of the connecting rod that is not in contact with the stirring shaft.

[0016] Preferably, an elastic reset component is fixedly connected to the inner wall of the auxiliary groove, and the other end of the elastic reset component is fixedly connected to the auxiliary sliding block.

[0017] Preferably, the baffle is arranged at an angle, and the baffle can only slide from bottom to top inside the slide groove, and cannot slide downward.

[0018] Preferably, a stirring rod is fixedly connected to the stirring shaft.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] (1) When the motor of the pre-hydrogenation dechlorination catalyst metering device is started, its output end drives the stirring shaft, the connecting rod and the pushing ball to rotate together. At this time, as the pushing ball rotates, the pushing ball enters the interior of the chute and continues to move along the inclined baffle. At this time, since the baffle is inclined, the baffle is subjected to a downward pressure during the rotation of the pushing ball, so that the force-bearing pulling block drives the force-bearing connecting plate and the sealing rod to move downward together, and then the sealing rod no longer seals the quantitative discharge pipe. Therefore, when the pushing ball rotates one circle with the stirring shaft, the catalyst can be quantitatively added once, thereby achieving quantitative addition of the catalyst, thereby ensuring the reaction effect and reaction speed.

[0021] (2) The catalyst quantitative device for pre-hydrodechlorination has a stirring rod, so as the stirring shaft rotates, the stirring rod can play the effect of mixing the catalyst and the raw material, thereby ensuring the normal catalytic reaction of the raw material.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0031] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0032] See also Figure 1-4 The utility model provides a technical solution: a catalyst quantitative device for pre-hydrogenation dechlorination, comprising a reactor 1, on which a feed pipe and a discharge pipe are arranged, and the feed pipe and the discharge pipe are respectively fixedly connected with connecting flanges;

[0033] The reactor 1 is fixedly connected with a catalyst storage device 2, and the catalyst storage device 2 is provided with a adding hole 5;

[0034] A motor 6 is fixedly connected to the bottom of the reactor 1, a stirring shaft 7 is rotatably connected to the inside of the reactor 1, and an output end of the motor 6 is fixedly connected to the stirring shaft 7;

[0035] A quantitative mechanism is arranged inside the reactor 1. Through the quantitative mechanism, the catalyst can be added in a predetermined amount, and no manual addition is required, thereby ensuring that the amount added is more accurate and reducing unnecessary cumbersome steps;

[0036] Furthermore, the quantitative mechanism includes a quantitative discharge pipe 9, which is fixedly connected to the inside of the reactor 1, and the quantitative discharge pipe 9 is interconnected with the catalyst storage device 2;

[0037] The quantitative discharging pipe 9 is internally slidably connected with an I-shaped sealing rod 10;

[0038] A support rod 11 is fixedly connected to the inner wall of the reactor 1, and a spring 13 is movably sleeved on the support rod 11;

[0039] The lower end of the sealing rod 10 is fixedly connected with a force-bearing connecting plate 12, and the force-bearing connecting plate 12 is slidably connected with the supporting rod 11;

[0040] The two ends of the spring 13 are fixedly connected to the force-bearing connecting plate 12 and the support rod 11 respectively;

[0041] When the force-bearing connecting plate 12 is forced to move downward, the sealing rod 10 is moved downward together. At this time, the spring 13 is forced to expand. When the sealing rod 10 moves, its waist position enters into the interior of the quantitative discharge pipe 9. Therefore, the sealing rod 10 no longer seals the quantitative discharge pipe 9, and then the catalyst flows out through the quantitative discharge pipe 9. Under the elasticity of the spring 13, when the external force disappears, the force-bearing connecting plate 12 and the sealing rod 10 are reset together, so the sealing rod 10 seals the quantitative discharge pipe 9.

[0042] Furthermore, a force-bearing pull block 14 is fixedly connected to the bottom of the force-bearing connecting plate 12, and a slide groove 15 is provided on one side of the force-bearing pull block 14;

[0043] An auxiliary groove 3 is provided inside the slide groove 15, an auxiliary slider 4 is slidably connected inside the auxiliary groove 3, a baffle 16 is fixedly connected to the auxiliary slider 4, and the baffle 16 is slidably connected inside the slide groove 15;

[0044] The baffle 16 is inclined and can only slide from bottom to top inside the slide slot 15, but cannot slide downward.

[0045] An elastic reset component 17 is fixedly connected to the inner wall of the auxiliary groove 3, and the other end of the elastic reset component 17 is fixedly connected to the auxiliary sliding block 4;

[0046] A connecting rod 18 is fixedly connected to the stirring shaft 7, and a pushing ball 19 is fixedly connected to the end of the connecting rod 18 that is not in contact with the stirring shaft 7;

[0047] When the motor 6 is started, its output end drives the stirring shaft 7, the connecting rod 18 and the pushing ball 19 to rotate together. At this time, as the pushing ball 19 rotates, the pushing ball 19 enters the interior of the chute 15 and continues to move along the inclined baffle 16. At this time, since the baffle 16 is inclined, the baffle 16 is subjected to a downward pressure during the rotation of the pushing ball 19, so that the force-bearing pull block 14 drives the force-bearing connecting plate 12 and the sealing rod 10 to move downward together, so that the sealing rod 10 no longer seals the quantitative discharge pipe 9. Therefore, when the pushing ball 19 rotates one circle with the stirring shaft 7, the catalyst can be quantitatively dosed once, thereby achieving quantitative delivery of the catalyst;

[0048] When the catalyst is no longer needed to be added, it is only necessary to make the output end of the motor 6 rotate in the opposite direction. At this time, the pushing ball 19 enters from the other opening of the chute 15. Due to the intervention of the pushing ball 19, the baffle 16 is forced to slide downward inside the chute 15 through the auxiliary slider 4. At this time, the force-bearing pull block 14 is in a stationary state, so the quantitative discharge pipe 9 is in a sealed state, and the catalyst cannot flow out;

[0049] Furthermore, a stirring rod 8 is fixedly connected to the stirring shaft 7;

[0050] By providing the stirring rod 8, as the stirring shaft 7 rotates, the stirring rod 8 can play the role of mixing the catalyst and the raw materials, thereby ensuring the normal catalytic reaction of the raw materials.

[0051] Working principle: when the motor 6 is started, its output end drives the stirring shaft 7, the connecting rod 18 and the pushing ball 19 to rotate together. At this time, as the pushing ball 19 rotates, the pushing ball 19 enters the interior of the chute 15 and continues to move along the inclined baffle 16. At this time, since the baffle 16 is inclined, the baffle 16 will be subjected to a downward pressure during the rotation of the pushing ball 19, so that the force-bearing pulling block 14 drives the force-bearing connecting plate 12 and the sealing rod 10 to move downward together, so that the sealing rod 10 no longer seals the quantitative discharge pipe 9. Therefore, when the pushing ball 19 rotates one circle with the stirring shaft 7, the catalyst can be quantitatively dosed once, thereby achieving quantitative delivery of the catalyst;

[0052] When the catalyst is no longer needed, it is only necessary to rotate the output end of the motor 6 in the opposite direction. At this time, the pushing ball 19 enters from another opening of the slide groove 15. Due to the intervention of the pushing ball 19, the baffle 16 is forced to slide downward inside the slide groove 15 through the auxiliary slider 4. At this time, the force-bearing pulling block 14 is in a stationary state, so the quantitative discharge pipe 9 is in a sealed state, and the catalyst cannot flow out.

[0053] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
