Description

Technical Field

[0001] This application relates to a carbon black production device, specifically a perforated plate used for collecting carbon black. Background Technology

[0002] In carbon black production, the carbon black generated from the cracking of feedstock oil in a reactor is cooled by equipment such as a high-temperature preheater, waste heat boiler, and oil preheater before entering a bag filter for collection. The filter bags in the bag filter are fixed to the enlarged holes in the perforated plate by elastic rings. For example... Figure 2 As shown, the bag filter is fixed to the shoulder of the enlarged perforation by an elastic ring. Since the bag filter and tube sheet are located in the carbon black exhaust gas environment, which is highly corrosive, and the shoulder is only 2mm thick, it is easily corroded, causing it to shrink or disappear. This results in the bag filter detaching from the perforation, rendering it abnormal and severely impacting carbon black production. If the shoulder is eliminated, the entire tube sheet needs to be replaced to ensure normal carbon black production, which is not only labor-intensive and time-consuming but also causes significant economic losses. Summary of the Invention

[0003] The purpose of this invention is to provide a perforated plate for collecting carbon black, which can prevent the enlarged holes from being corroded by carbon black flue gas, and eliminate the need to replace the entire perforated plate during maintenance, thereby reducing maintenance time and difficulty and minimizing economic losses.

[0004] The technical solution adopted by this utility model is: a tube sheet for collecting carbon black, wherein at least two enlarged holes are provided on the tube sheet, the enlarged holes are arranged in a periodic array, the inner wall of the enlarged holes is provided with a shoulder, a collar is movably provided in the enlarged holes, the outer wall of the collar is in contact with the inner wall of the enlarged holes, and the inner wall of the collar is also provided with a shoulder.

[0005] Furthermore, the collar and the enlarged hole are interference fit.

[0006] Furthermore, the collar is made of cast iron.

[0007] The beneficial effects of this utility model are as follows: This utility model adds a collar inside the enlarged hole to isolate the enlarged hole from the carbon black flue gas, preventing the carbon black flue gas from corroding the enlarged hole and thus damaging the perforated plate. The connection method between the bag filter and the collar is the same as the connection method between the bag filter and the enlarged hole; therefore, the modification difficulty and cost are low. The shoulder on the collar can cooperate with the shoulder inside the enlarged hole to prevent the collar from being pulled out of the perforated plate by the upward force of the bag filter for a long time. During maintenance, only the severely corroded collar needs to be replaced; there is no need to disassemble and replace the entire perforated plate, effectively reducing maintenance time and difficulty, and minimizing economic losses.

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Many specific details are set forth in the following description to provide a full understanding of the present utility model; however, the present utility model may also be implemented in other ways different from those described herein, and therefore, the present utility model is not limited to the specific embodiments disclosed below.

[0015] like Figure 3 and Figure 4 As shown, a perforated plate for collecting carbon black is provided. The perforated plate 1 has at least two enlarged holes 2 arranged in a periodic array. The inner wall of each enlarged hole 2 is provided with a shoulder 3. A collar 4 is movably disposed within each enlarged hole 2. The outer wall of the collar 4 fits against the inner wall of the enlarged hole 2, and the inner wall of the collar 4 is also provided with a shoulder 3. In this embodiment of the invention, the collar 4 and the enlarged hole 2 are interference-fitted, so that although the collar 4 and the enlarged hole 2 are movably connected, the collar 4 can be firmly installed within the enlarged hole 2 and is easy to disassemble. The collar 4 is made of the same material as the perforated plate 1, such as cast iron.

[0016] The working principle of this utility model embodiment is as follows: the collar 4 is installed inside the enlarged hole 2 of the tube sheet 1, and the collar 4 can isolate the carbon black smoke from the inner wall of the enlarged hole 2. Figure 4As shown, the bag filter 5 is fixed to the shoulder 3 of the collar 4 by an elastic ring 6. During carbon black production, the bag filter 5 exerts an upward pulling force on the collar 4 due to the carbon black flue gas. However, under the action of the shoulder 3 on the collar 4 and the shoulder 3 on the enlarged hole 2, the collar 4 can be stably locked in the enlarged hole 2 and will not fall out of the enlarged hole 2 due to the pulling force of the bag filter 5. Due to the obstruction of the collar 4, the carbon black flue gas can only corrode the collar 4 and will not damage the tube sheet 1. The bag filter 5 can always be fixed in the enlarged hole 2, effectively avoiding the impact on production caused by the bag filter 5 falling out. At the same time, during maintenance, only the severely corroded collar 4 needs to be replaced, without disassembling and replacing the entire tube sheet 1, greatly reducing the difficulty and time of maintenance and effectively reducing economic losses.

[0017] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
