Description

Technical Field

[0001] The utility model relates to the technical field of pressure balance in green carbon black production, in particular to a pressure balance device for a cyclone separator in carbon black production. Background Art

[0002] Carbon black flue gas is a mixture of reaction gas and carbon black before the carbon black is collected in the carbon black production process. It mainly contains carbon black, carbon monoxide, carbon dioxide, water vapor and other reaction gases. Carbon black can be obtained by separation. Carbon black flue gas is commonly separated by a cyclone separator in the production process, and the centrifugal force of the cyclone separator is used to separate it to obtain carbon black powder. The carbon black powder passes through a wet granulation system to form carbon black pellets. During the use of the cyclone separator, due to the relatively large pressure fluctuation inside the cyclone separator, the pressure entering the powder carbon black storage tank also changes. The unstable pressure causes the conveying amount of carbon black dust in the powder carbon black storage tank to change constantly, thus affecting the granulation quality of the granulator and resulting in uneven particle sizes of the granules.

[0003] Therefore, it is necessary to propose a technology to improve the above defects. Summary of the Utility Model

[0014] It should be noted that the drawings provided in this embodiment only illustrate the basic concept of the present invention in a schematic manner. Although only the components related to the present invention are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation, the form, quantity, positional relationship, and proportion of each component in actual implementation can be arbitrarily changed on the premise of implementing the technical solution of the present invention, and the component layout form may also be more complex. Embodiment

[0015] This embodiment provides a pressure balance device for a cyclone separator in carbon black production. Refer to the attached Figure 1, the device includes a cyclone separator 1, a fan 2 is arranged on the left side of the cyclone separator 1, the other end of the fan 2 is provided with a main bag filter 3, a dust removal device 4 is installed on the top of the cyclone separator 1, a breathing valve 5 is installed above the dust removal device 4, and a pressure gauge 12 is also arranged between the dust removal device 4 and the breathing valve 5 for real-time monitoring of the internal pressure. A valve A6 is also arranged on the right side of the cyclone separator 1, and the valve A6 is connected to the cyclone separator 1 through a pipeline. In addition, the right side of the cyclone separator 1 is connected to the valve A6 through a pipeline. An airtight valve A7 is arranged at the bottom of the cyclone separator 1, and the other end of the airtight valve A7 is installed with a powdered carbon black storage tank 8. A balance pipe 13 is arranged at the bottom of the powdered carbon black storage tank 8, and an airtight valve B9 is arranged on the surface of the balance pipe 13. A conveyor 11 is arranged on the other side of the balance pipe 13. A valve B10 is also arranged on the side of the powdered carbon black storage tank 8. The valve B10 is connected to the powdered carbon black storage tank 8 through a pipeline, and the other end is connected to the conveyor 11 through a pipeline. The valve B10 and the airtight valve B9 are used synchronously and interlocked, that is, the opening and closing of the valve B10 are synchronized with the airtight valve B9, and they are opened or closed simultaneously and interlocked.

[0016] Still referring to the appendix Figure 1 , when the device is in use, the carbon black flue gas enters the main bag filter 3, and the carbon black attached to the main bag filter 3 is purged with compressed air so that the carbon black falls into the hopper of the main bag filter 3. The collected carbon black is transported from the main bag filter 3 to the cyclone separator 1 by the fan 2. After the carbon black dust separated by the cyclone separator 1 directly enters the powdered carbon black storage tank 8, the cyclone separator 1 uses centrifugal force to separate the carbon black dust from the air flow. Its working principle is that the dust-containing air flow enters the cyclone separator 1 at high speed through the fan, and the air flow changes from a linear motion to a circular motion and spirals downward along the inner wall from the cylindrical body towards the cone. Under the action of centrifugal force, the particles are thrown towards the wall of the device. After the dust particles contact the wall of the device, they lose their inertial force and fall along the wall surface after losing power, enter the cylindrical body and fall into the powdered carbon black storage tank 8, and are transported to the conveyor 11 by the airtight valve 9 after entering the powdered carbon black storage tank 8. In addition, the rotating downward air flow continuously flows into the central part of the cyclone separator 1 during the downward process, and then forms a centripetal radial air flow. This part of the air flow constitutes a rotating upward inner swirl flow. Finally, the purified gas is discharged after being purified by the dust removal device 4.

[0017] To sum up, by installing a pressure gauge and a breathing valve above the cyclone separator, the present utility model can effectively maintain the pressure balance inside the cyclone separator. In addition, a balance pipe is installed between the powdered carbon black storage tank and the conveyor, and an airtight valve B is installed on the balance pipe. The airtight valve B and the balance pipe are used synchronously and interlocked, which can ensure the pressure balance between the powdered carbon black storage tank and the conveyor, effectively solve the problem of large pressure fluctuations in the cyclone separator during the production process, resulting in uneven feeding, and stabilize the granulation quality.
