Description

Technical Field

[0001] The utility model relates to the technical field of chlorine - passing reaction, in particular to a tail - gas pressure linkage control device for chlorine - passing reaction. Background Technique

[0002] Chlorine is a colorless gas with a pungent smell, liquid at room temperature and gaseous at normal temperature. It has very strong oxidizing and corrosive properties and will react violently with many substances, so it needs to be used with caution. During the chlorine - passing reaction process, reaction tail - gas is generated. The effective control and recycling of the reaction tail - gas are important links in the process technology.

[0003] A reaction tail - gas pressure measurement and control device provided by the publication number "CN219935175U" consists of a main tail - gas pipeline, a reaction kettle, an air regulating valve, a U - shaped differential pressure gauge, an air - flow damper, etc. One of the innovative points is that when measuring the weak pressure in the tail - gas pipeline, the conversion thinking concept of a water - based U - shaped differential pressure gauge is introduced, effectively solving the problem that it is difficult to measure the weak positive or negative pressure in the tail - gas pipeline with an ordinary pressure gauge or vacuum gauge due to their large measurement ranges, and then implementing effective regulation; the second innovative point is that an air - flow damper is installed at the tail - gas outlet of the reaction kettle, which can effectively suppress the gas - liquid entrainment phenomenon. The reaction tail - gas pressure measurement and control device disclosed by the technical solution of the utility model also has the characteristics of simple structure, easy assembly, low cost, and convenient operation.

[0004] However, the following problems still exist in the implementation of the above - mentioned device:

[0005] The control devices in the prior art and the above - mentioned scheme can detect the pressure in the reaction kettle, effectively solve the problem that it is difficult to measure the weak positive or negative pressure in the tail - gas pipeline with an ordinary pressure gauge or vacuum gauge due to their large measurement ranges, and when the mixed gas flow passes through the air - flow damper, most of the reaction liquid will fall back into the reaction kettle due to the sudden speed reduction. However, considering that during the process of the reaction liquid falling back at a reduced speed, some of the reaction liquid will fall into the reaction kettle along with the main tail - gas pipeline, and some viscous materials in the reaction liquid will adhere to the inner wall of the main tail - gas pipeline, causing blockage, thus affecting the practicability of the control device. Content of the Utility Model

[0006] The purpose of the utility model is to provide a tail - gas pressure linkage control device for chlorine - passing reaction to solve the problems put forward in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] A tail gas pressure linkage control device for chlorine passing reaction, comprising a reaction kettle, an air regulating valve, a main tail gas pipeline, a U-shaped differential pressure gauge and an air flow damper. The air regulating valve is fixedly installed at the top of the reaction kettle. The main tail gas pipeline is fixedly connected to the top of the reaction kettle. The air flow damper is fixedly installed on the surface of the main tail gas pipeline. The U-shaped differential pressure gauge is fixedly installed on one side of the main tail gas pipeline. A shell is fixedly connected to the surface of the main tail gas pipeline.

[0009] A vibration mechanism is arranged inside the shell, which can make the materials adhering to the inner wall of the main tail gas pipeline fall back into the reaction kettle through vibration.

[0010] Preferably, the vibration mechanism includes a positioning ring fixedly connected to the surface of the main tail gas pipeline. One side of the positioning ring is fixedly connected with a guide rod. A linkage block is slidably connected to the surface of the guide rod. A tension spring is sleeved on the surface of the guide rod. One end of the tension spring is fixedly connected with one side of the linkage block. The other end of the tension spring is fixedly connected with the surface of the positioning ring. A knocking rod is fixedly connected to the bottom of one side of the linkage block. An extrusion rod is fixedly connected to the top of one side of the linkage block.

[0011] Preferably, the vibration mechanism further includes a motor fixedly installed at the bottom of the positioning ring. The output end of the motor penetrates to the top of the positioning ring and is fixedly connected with a gear. A toothed ring is meshed and connected to one side of the gear. Four extrusion blocks used in cooperation with the extrusion rod are fixedly connected to the top of the toothed ring.

[0012] Preferably, a diffusion mechanism is arranged on the surface of the main tail gas pipeline, which can diffuse the vibration force generated by the vibration mechanism and improve the falling rate of the materials.

[0013] The diffusion mechanism includes a protection ring fixedly connected to the surface of the main tail gas pipeline. One side of the protection ring is in contact with one end of the knocking rod. A spring is fixedly connected to the bottom of the protection ring. A counterweight block is fixedly connected to the bottom of the spring.

[0014] Preferably, a guide hole is opened on one side of the linkage block, and the guide hole is used in cooperation with the guide rod.

[0015] Preferably, sliding blocks are fixedly connected to both sides of the bottom of the toothed ring, and sliding grooves used in cooperation with the sliding blocks are opened on the top of the positioning ring.

[0016] Preferably, both sides of the extrusion block are in a slope shape.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. In this utility model, considering that during the process of the reaction liquid flowing back at a decreasing speed, some of the reaction liquid will fall into the reaction kettle along the main tail gas pipe, and some viscous materials in the reaction liquid will adhere to the inner wall of the main tail gas pipe, causing blockage. Therefore, by setting a vibration mechanism, the motor can be started to drive the gear to rotate. The gear meshes with the toothed ring, so the toothed ring will be driven to rotate around the sliding block and the sliding groove. While the toothed ring rotates, it will drive the four extrusion blocks to rotate. When the inclined side of the extrusion block contacts the extrusion rod, as Figure 6 shown, the extrusion rod will be extruded and move to one side, simultaneously driving the linkage block and the knocking rod to move. At the same time, the linkage block will drive the tension spring to be in a stretched state. Then, when the extrusion block does not contact the extrusion rod, affected by the pulling force generated by the tension spring, the linkage block will drive the knocking rod to suddenly reset and knock on the surface of the protective ring, generating a vibration force transmitted to the main tail gas pipe, and thus generating vibrations through cyclic intermittent knocking to shake off the materials adhering to the inner wall of the main tail gas pipe;

[0019] 2. In this utility model, considering that the generated vibration force is on one side of the main tail gas pipe, the vibration force in some areas may not be sufficient to shake off the materials. Therefore, by setting a diffusion mechanism, while the knocking rod knocks on the protective ring to generate a vibration force, it will be conducted to the spring, causing the spring and the counterweight to vibrate, dispersing the vibration force, thereby improving the vibration effect;

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0029] Please refer to Figures 1 - 6 , the present utility model provides a technical solution:

[0030] Embodiment 1:

[0031] A tail gas pressure linkage control device for chlorine passing reaction includes a reaction kettle 1, an air regulating valve 2, a main tail gas pipeline 3, a U-shaped differential pressure gauge 4 and an air flow damper 5. The air regulating valve 2 is fixedly installed on the top of the reaction kettle 1, the main tail gas pipeline 3 is fixedly connected to the top of the reaction kettle 1, the air flow damper 5 is fixedly installed on the surface of the main tail gas pipeline 3, the U-shaped differential pressure gauge 4 is fixedly installed on one side of the main tail gas pipeline 3, and a housing 6 is fixedly connected to the surface of the main tail gas pipeline 3;

[0032] A vibration mechanism is arranged inside the housing 6, which can make the materials adhering to the inner wall of the main tail gas pipeline 3 fall back into the reaction kettle 1 through vibration.

[0033] One implementation mode of this Embodiment 1 is: the vibration mechanism includes a positioning ring 7 fixedly connected to the surface of the main tail gas pipeline 3, a guide rod 8 is fixedly connected to one side of the positioning ring 7, a linkage block 9 is slidably connected to the surface of the guide rod 8, a tension spring 10 is sleeved on the surface of the guide rod 8, one end of the tension spring 10 is fixedly connected to one side of the linkage block 9, the other end of the tension spring 10 is fixedly connected to the surface of the positioning ring 7, a knocking rod 11 is fixedly connected to the bottom of one side of the linkage block 9, and an extrusion rod 12 is fixedly connected to the top of one side of the linkage block 9;

[0034] The vibration mechanism further includes a motor 13 fixedly installed at the bottom of the positioning ring 7. The output end of the motor 13 penetrates to the top of the positioning ring 7 and is fixedly connected with a gear 14. One side of the gear 14 is meshed with a toothed ring 15. The top of the toothed ring 15 is fixedly connected with four extrusion blocks 16 which are used in cooperation with the extrusion rod 12;

[0035] In this embodiment, considering that during the process of the reaction liquid descending and flowing back, some of the reaction liquid will fall into the reaction kettle 1 along with the main tail gas pipeline 3. Some viscous materials in the reaction liquid will adhere to the inner wall of the main tail gas pipeline 3, causing blockage. Therefore, by setting the vibration mechanism, the motor 13 can be started to drive the gear 14 to rotate. The gear 14 is meshed with the toothed ring 15, so the toothed ring 15 will be driven to rotate around the sliding block 21 and the sliding groove 22. When the toothed ring 15 rotates, the four extrusion blocks 16 will be driven to rotate. When the inclined side part of the extrusion block 16 contacts the extrusion rod 12, as Figure 6 shown, the extrusion rod 12 will be extruded and move to one side, and at the same time drive the linkage block 9 and the knocking rod 11 to move. At the same time, the linkage block 9 will drive the tension spring 10 to be in a stretched state. Then when the extrusion block 16 does not contact the extrusion rod 12, affected by the pulling force generated by the tension spring 10, the linkage block 9 will drive the knocking rod 11 to suddenly reset and knock on the surface of the protection ring 17, generating a vibration force transmitted to the main tail gas pipeline 3, and knocking intermittently in this cycle to generate vibration, so as to shake off the materials adhered to the inner wall of the main tail gas pipeline 3;

[0036] It should be noted that in the figure, S1 is the movement track of the extrusion block 16, and S2 is the movement track of the extrusion rod 12.

[0037] Preferably, a guiding hole 20 is formed on one side of the linkage block 9, and the guiding hole 20 is used in cooperation with the guiding rod 8;

[0038] In this embodiment, by setting the guiding hole 20, when the inclined side part of the extrusion block 16 contacts the extrusion rod 12, the structures such as the extrusion rod 12 and the linkage block 9 can be restricted to slide only along the track of the guiding rod 8.

[0039] Preferably, sliding blocks 21 are fixedly connected to both sides of the bottom of the toothed ring 15, and sliding grooves 22 which are used in cooperation with the sliding blocks 21 are formed on the top of the positioning ring 7;

[0040] In this embodiment, by setting the sliding blocks 21 and the sliding grooves 22, the rotation track of the toothed ring 15 can be restricted, and at the same time, the toothed ring 15 can rotate more stably during the rotation process.

[0041] Preferably, both sides of the extrusion block 16 are in a slope shape;

[0042] In this embodiment, by providing the extrusion block 16, the two sides of the extrusion block 16 are set to be ramp-shaped. When the hypotenuse part of the extrusion block 16 contacts the extrusion rod 12, the structures such as the extrusion rod 12 will slide along the guide rod 8, playing a role in transmission.

[0043] Embodiment 2:

[0044] On the basis of Embodiment 1, in this embodiment, the vibration mechanism can generate vibration by knocking to shake the material back into the reaction kettle 1. However, considering that the generated vibration force is on one side of the main tail gas pipe 3, the vibration force in some areas may not be sufficient to shake the material off. A diffusion mechanism is provided on the surface of the main tail gas pipe 3 of the present application, which can diffuse the vibration force generated by the vibration mechanism and improve the rate of material falling;

[0045] The diffusion mechanism includes a protective ring 17 fixedly connected to the surface of the main tail gas pipe 3. One side of the protective ring 17 contacts one end of the knocking rod 11. A spring 18 is fixedly connected to the bottom of the protective ring 17, and a counterweight 19 is fixedly connected to the bottom of the spring 18;

[0046] In this embodiment, considering that the generated vibration force is on one side of the main tail gas pipe 3 and the vibration force in some areas may not be sufficient to shake the material off, a diffusion mechanism is provided. When the knocking rod 11 knocks on the protective ring 17 to generate a vibration force, it will be transmitted to the spring 18, causing the spring 18 and the counterweight 19 to vibrate and disperse the vibration force, thereby improving the vibration effect;

[0047] It solves the problem that considering the generated vibration force is on one side of the main tail gas pipe 3 and the vibration force in some areas may not be sufficient to shake the material off.

[0048] Working principle: By starting the motor 13, the gear 14 is driven to rotate. The gear 14 meshes with the toothed ring 15, so the toothed ring 15 is driven to rotate around the sliding block 21 and the sliding groove 22. While the toothed ring 15 rotates, it drives the four extrusion blocks 16 to rotate. When the hypotenuse part of the extrusion block 16 contacts the extrusion rod 12, as Figure 6 shown, the extrusion rod 12 will be extruded and move to one side, simultaneously driving the linkage block 9 and the knocking rod 11 to move. At the same time, the linkage block 9 will drive the tension spring 10 to be in a stretched state. Then, when the extrusion block 16 does not contact the extrusion rod 12, affected by the pulling force generated by the tension spring 10, the linkage block 9 will drive the knocking rod 11 to suddenly reset and knock on the surface of the protective ring 17, generating a vibration force transmitted to the main tail gas pipe 3, and knocking intermittently in this cycle to generate vibration and shake off the material adhering to the inner wall of the main tail gas pipe 3;

[0049] Meanwhile, while the striking rod 11 generates a vibration force when striking the protective ring 17, the vibration force will be conducted to the spring 18, causing the spring 18 and the counterweight 19 to vibrate, dispersing the vibration force, thereby improving the vibration effect.

[0050] It should be noted that the motor 13 is a device or equipment existing in the prior art, or a device or equipment that can be realized by the prior art, and the specific composition and principle of the power supply of the motor 13 are clear to those skilled in the art, so no further detailed description will be given.

[0051] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
