Description

Technical Field

[0001] This utility model relates to the field of cracked C5 processing technology, and in particular to a cracked C5 desulfurization device. Background Technology

[0002] Desulfurization is a key process in petroleum refining and chemical production, aiming to remove sulfides (such as hydrogen sulfide, mercaptans, thiophene, etc.) from products through chemical or physical methods to meet environmental regulations regarding sulfur content. Cracked C5 fraction desulfurization is a crucial process in the petrochemical industry, designed to remove sulfides (such as H2S, mercaptans, thiophene, etc.) to meet the quality requirements or environmental standards of downstream products.

[0003] In desulfurization processes, the mixing efficiency, temperature control accuracy, and reaction contact area of ​​the reactor are key factors affecting desulfurization performance. Traditional reactors often suffer from low reaction efficiency, high energy consumption, and unstable product quality due to their simple stirring structure, uneven temperature distribution, and insufficient contact between the desulfurizing agent and the liquid phase. Furthermore, existing equipment also has shortcomings in safety control (such as pressure release and dynamic temperature monitoring) and thermal energy utilization efficiency.

[0004] This reactor, through structural innovation and system synergy, solves the problems of uneven mixing, lag in temperature control, and insufficient safety of traditional equipment, significantly improving desulfurization efficiency and product quality, and is suitable for industrial applications of desulfurization of cracked C5.

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a pyrolysis C5 desulfurization device to solve the technical problem of oil desulfurization treatment.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A desulfurization device for C5 cracking, including a reaction vessel: the core reaction container with a built-in multi-layer stirring system;

[0010] The reactor is equipped with a feed inlet at the top for injecting cracked C5 feedstock and desulfurization additives.

[0011] A drive pump is installed in the middle of the upper part of the reactor. Below the drive pump is a stirring system, which includes a rotating shaft, a main stirring shaft, and a secondary stirring shaft. The rotating shaft is coaxially fixed to the outer wall of the reactor via a coupling below the drive pump. The main stirring shaft and the secondary stirring shaft are fixedly installed on the rotating shaft. The main stirring shaft has a T-shaped structure, which can realize stirring in both horizontal and vertical directions to improve efficiency. In addition, the T-shaped structure of the main stirring shaft is close to the outside of the reactor, which better integrates the external heating temperature inward and helps to improve the uniformity of the heating system. Combined with the secondary shaft, it forms a multi-level shear force to improve the stirring and mixing efficiency.

[0012] Preferably, an outer insulation layer is provided below the reactor to wrap the reactor, reduce heat loss, and maintain the stability of the reaction temperature. A temperature control module is provided on the outside of the reactor and the inside of the outer insulation layer. The temperature control module includes a temperature regulating device, and the temperature regulating device is provided with a ring-wound heating tube. The temperature regulating device controls the reaction temperature through a circulating medium to optimize the desulfurization efficiency.

[0017] Preferably, there is a gap between the first guide plate and the rotating shaft, the inner side of the second guide plate is connected to the rotating shaft through a bushing, and the outer side of the second guide plate is not adjacent to the inner side of the reactor. The oil flowing through the stirring and mixing channel below mixes the oil through the alternating first guide plate on the inner side and the second guide plate on the outer side, thereby increasing the contact area and time between the desulfurizing agent and the cracked C5, thus improving the efficiency and quality of desulfurization.

[0018] Preferably, an upper extraction port is provided on the outer side of the upper part of the reactor, which can extract the clear liquid from the upper part of the reactor.

[0019] Preferably, several sets of pressure relief valves are installed above the reactor to automatically release excessive pressure when the set pressure is exceeded, ensuring equipment safety.

[0020] (III) Beneficial Effects

[0021] The cracked C5 enters the reactor through the feed inlet, and the desulfurizing agent is injected at the same time. The main and auxiliary stirring shafts are started, and high-intensity mixing is formed with the guide plate. The temperature control device controls the reaction temperature through the circulating medium to optimize the desulfurization efficiency. After desulfurization is completed, the product is discharged through the drain pipe, and the waste liquid is discharged through an independent pipeline. The temperature measuring instrument and pressure relief valve monitor the entire process to ensure safe and stable operation.

[0022] Multi-layer stirring system: It adopts a combination design of T-shaped stirring main shaft and secondary shaft. The main shaft is close to the inner wall of the reactor.

[0023] Dynamic temperature control module: It achieves precise temperature control through a ring-wound heating tube and a circulating medium (such as heat transfer oil). Combined with real-time feedback data from a temperature measuring instrument, it dynamically adjusts the reaction temperature to the optimal temperature range (50-80℃) to ensure that the reaction proceeds efficiently and stably.

[0024] Optimized structure of the guide plate: The first guide plate and the second guide plate are set in the reactor. The oil flow path is extended through the staggered channels, which increases the contact area and time between the desulfurizing agent and the cracked C5, and further improves the reaction efficiency.

[0025] Safety and functionality are integrated in the design: a pressure relief valve automatically releases excess pressure, and a solenoid valve controls the drain pipe for precise material discharge; the upper extraction port separates the upper clear liquid, reducing impurity interference. An external insulation layer reduces heat loss and further optimizes energy consumption. Attached Figure Description
