Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of carbon black production, in particular to a safety diffusion device for carbon black production. BACKGROUND

[0002] The waste gas generated in chemical production is mostly discharged into the air through a high chimney, and the waste gas will cause great pollution to the atmosphere. In the existing carbon black production process, the waste gas discharged from the main bag, waste bag, main vein and waste vein is mostly conveyed to a desulfurization tower for desulfurization and denitrification treatment before being discharged into the atmosphere. In addition, if the production system is unstable during carbon black production, the pressure in the box of the main bag and the waste bag will be too large, which will damage the bag filter in the box, and the box needs to be ventilated with the atmosphere during shutdown and maintenance.

[0003] For example, a safety diffusion device applied to carbon black production disclosed in CN114504883B includes a cylinder, the upper part of which is hinged with a sealing cover; a gas cylinder is arranged on the side of the cylinder and is movably connected with the sealing cover, and the gas cylinder is used to drive the sealing cover to move; a control valve is connected with the production system and the compressed air output device at the input end, and is connected with the gas cylinder at the output end, and is used to control the action of the gas cylinder according to the pressure state of the production system. The present application drives the sealing cover by the gas cylinder to control the opening and closing of the cylinder, controls the action of the gas cylinder by the control valve to automatically control the opening and closing of the cylinder, and the setting of the gas cylinder can not only ensure the sealing performance between the sealing cover and the cylinder, but also control the action of the gas cylinder according to the pressure state of the production system. When the pressure of the production system is too high, the cylinder inside is timely relieved to ensure that the bag filter inside the cylinder is not damaged.

[0004] In the process of carbon black production and tail gas collection and delivery, the above-mentioned diffusion valve plays a safety protection role. Once the system pressure exceeds the safe pressure range, the automatic safety diffusion valve and the manual safety diffusion are used for safety adjustment. When the manual diffusion is used, the iron filings and the like in the pipeline will be discharged together with the tail gas. Whether the ground around the diffusion is dirty or not, the manual diffusion pipeline is severely corroded, which pollutes the environment. In the process of tail gas collection and delivery, the personnel on site manually operate, the pressure is unstable, the reaction is slow, and the personal safety is endangered.

[0020] Compared with the prior art, the present application has the following beneficial effects:

[0021] 1. When the pressure of the tail gas is too large, the flat plate, the first communicating cylinder, the first conical cylinder and the second communicating cylinder rotate upward, the tail gas can be discharged from the first through hole, the device is relieved, the tail gas is continuously discharged, a rotational flow is formed in the second conical cylinder, and debris particles can be thrown out to a certain extent, the purity of the tail gas release is improved, the particles sprayed from the first through hole can be re-discharged into the diffusion pipe body from the second through hole, part of the carbon black and iron filings are prevented from flowing out, and environmental pollution is reduced.

[0022] 2. The diameter of the diffusion pipe body 21 is expanded from the original φ700, φ500 to φ900, the filtering area is greatly improved, manual diffusion is removed, equipment damage caused by pressure fluctuation in the process is effectively solved, and the protection effect is good.

[0023] 3. The airflow ejected from the first through hole can continuously drive the fan blades, inner cylinder, and second conical cylinder to rotate. During the rotation of the second conical cylinder, the airflow will be driven to vortex, which will then throw the heavier particles to both sides of the second conical cylinder. Finally, the particles will be poured back into the venting pipe body through the second through hole. This can effectively separate solids and gases, prevent particles from being discharged outside the venting pipe body, and further play a protective role.

[0024] 4. By setting up drainage holes, it can effectively drain water and remove dust during rain.

[0025] 5. The six arc-shaped plates are combined to form a circular structure, which is closed at the upper end of the inner cylinder, further sealing the vent pipe body. When the exhaust gas pressure is too high, multiple arc-shaped plates unfold simultaneously, limiting the upward splashing particles. Therefore, the debris particles can only be discharged downwards, which is suitable for the safe emission of exhaust gas.

[0026] 6. Through the cooperation between the one-way ratchet and the one-way pawl, the inner cylinder can be driven to rotate together during the rotation of the motor, which can drive the arc plate to close in one direction, ensuring that the device can be opened and closed and is easy to operate manually.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0037] Embodiment one: please refer to Figures 1-4 The present application provides a technical solution: a safe diffusion device for carbon black production, which comprises a production mechanism 1 and a diffusion pipe mechanism 2 mounted on the production mechanism 1. The diffusion pipe mechanism 2 plays a safety protection role in the tail gas discharge process of the carbon black production process.

[0038] The diffusion pipe mechanism 2 comprises a diffusion pipe body 21, and the tail gas is discharged from the diffusion pipe body 21.

[0039] An embedded groove 22 is formed in the upper end of the inner wall of the diffusion pipe body 21, and a spiral inner groove 23 is formed in the lower end of the groove wall of the embedded groove 22.

[0040] The venting pipe mechanism 2 is internally provided with a first limiting mechanism 4. The first limiting mechanism 4 includes a flat plate 41. The outer periphery of the flat plate 41 is provided with a threaded protrusion 47. The threaded protrusion 47 is threadedly connected to the spiral inner groove 23. The upper end of the flat plate 41 is connected to a first connecting cylinder 42. The upper end of the first connecting cylinder 42 is connected to a first conical cylinder 43. The upper end of the first conical cylinder 43 is connected to a second connecting cylinder 44. The outer periphery of the second connecting cylinder 44 is provided with a first through hole 45. The first through hole 45 has an inclined structure.

[0041] The upper end of the first limiting mechanism 4 is provided with a dust removal mechanism 5. The dust removal mechanism 5 includes an inner cylinder 51 that is rotatably installed on the outer periphery of the vent pipe body 21. A second conical cylinder 52 is fixedly installed on the inner wall of the inner cylinder 51. The lower end of the second conical cylinder 52 is connected to a limiting cylinder 53. A second connecting cylinder 44 is disposed inside the limiting cylinder 53.

[0042] The limiting cylinder 53 blocks the first through hole 45 of the second connecting cylinder 44, so that the flat plate 41, the first connecting cylinder 42, the first conical cylinder 43, and the second connecting cylinder 44 are combined into a cylindrical structure that is closed at the top and open at the bottom. The exhaust gas enters the vent pipe body 21 and surges upward. The exhaust gas will not leak from the top and also prevents rainwater or other dust from entering the production mechanism 1, thus having a safety sealing function.

[0043] The vent pipe body 21 is fixed in position. When the pressure of the exhaust gas is too high, the pressure pushes the second connecting cylinder 44 upward. The second connecting cylinder 44 and the plate 41 move upward. At this time, the threaded protrusion 47 on the outer periphery of the plate 41 is threadedly connected to the spiral inner groove 23. That is, the plate 41, the first connecting cylinder 42, the first conical cylinder 43, and the second connecting cylinder 44 rotate upward until the first through hole 45 of the second connecting cylinder 44 is higher than the limiting cylinder 53. The exhaust gas can be discharged from the first through hole 45 to relieve pressure on the device. After the pressure is restored, the second connecting cylinder 44 is reset and can block the vent pipe body 21 again.

[0044] During the pressure release process, the exhaust gas is discharged through the first through hole 45, which has an inclined structure. The exhaust gas is continuously discharged and will be sprayed directly onto the inner wall of the second conical cylinder 52, thereby forming a vortex in the second conical cylinder 52. To a certain extent, it can throw out debris particles and improve the purity of the exhaust gas release.

[0045] The second conical cylinder 52 has a second through hole 54. Particles ejected from the first through hole 45 can be discharged back into the vent pipe body 21 through the second through hole 54, preventing some carbon black and iron filings from flowing out and reducing environmental pollution. At the same time, the exhaust gas is discharged upward in a spiral shape, which has a certain anti-clogging effect and also ensures the uniformity of exhaust gas release.
