Description

Technical Field

[0001] This utility model relates to the field of heavy aromatic hydrocarbon treatment technology, specifically to a raw material heavy aromatic hydrocarbon separation and impurity removal device that is easy to clean. Background Technology

[0002] Heavy aromatics refer to mixed aromatics with a molecular weight greater than xylene. As an important chemical raw material, they are widely used in various fields such as petrochemicals and fine chemicals. In the production and processing of heavy aromatics, separation and impurity removal are essential and crucial steps. The purpose is to remove various impurities from heavy aromatics, such as gums, asphaltenes, metal salts, and other high-boiling-point impurities, in order to improve the quality and purity of heavy aromatics and meet the needs of different industrial production.

[0003] A utility model patent with publication number CN222876754U discloses an aromatic oil transfer device with impurity removal function, including a storage tank. A discharge pipe is connected to one side of the bottom of the storage tank, and a valve is installed on the discharge pipe. An annular shell is connected above the storage tank, and a cover plate is installed on the top of the annular shell. Feed pipes are connected to both sides above the cover plate, and pipe caps are installed on the feed pipes. An inner annular shell is provided inside the annular shell. An upper annular plate is fixed above the inner annular shell, and a lower annular plate is fixed inside the annular shell. This transfer device conveys the aromatic oil to be transferred through the feed pipes into the annular shell.

Therefore, there is an urgent need to design a raw material heavy aromatics separation and impurity removal device that is easy to clean, in order to solve the problems of difficult cleaning, low efficiency, and high cost existing in the prior art.

[0049] Working Principle: During operation, the raw material heavy aromatics enter the tank body 01 through the feed pipe 45 on the side of the tank cover 4. It first passes through the upper splicing section 3, at which point the motor 8 is started. The motor 8 drives the scraping component 7 to rotate, scraping away any dirt that may be attached to the inner wall of the upper splicing section 3. Next, the raw material enters the impurity removal component 5 in the middle splicing section 2. Multiple filter plates 52 arranged from top to bottom in the impurity removal component 5 have progressively smaller pore sizes, gradually filtering out particulate impurities from the raw material heavy aromatics. The filtered raw material then enters the adsorption box 51. The molecular sieve 511 in the adsorption box 51 removes non-aromatic hydrocarbons and polar impurities from the heavy aromatics through pore size sieving and polar adsorption, completing the impurity removal process. The impurity-removed heavy aromatics enter the lower splicing section 1 and finally exit the device through the discharge pipe 13 on the side of the lower splicing section 1. The tank body 01 of the device is divided into a lower splicing part 1, a middle splicing part 2 and an upper splicing part 3. The drive cylinders 6 on both sides of the lower splicing part 1 can drive the upper splicing part 3 to move up and down, which facilitates the disassembly and assembly of the middle splicing part 2 and makes it convenient to clean and maintain the inside of the device. At the same time, the sealing rings 24 at the connection of each splicing part can ensure the sealing of the device.

[0050] In summary, compared with the prior art, this application divides the tank body 01 into a lower splicing part 1, a middle splicing part 2, and an upper splicing part 3. The lower splicing part 1 and the upper splicing part 3 are driven by the drive cylinder 6 to press the middle splicing part 2 together, thereby forming the entire tank body 01. The middle splicing part 2 is equipped with a purification component 5, which can effectively remove impurities in heavy aromatics. The purification component 5 can filter out particulate matter. Then, the molecular sieve 511 can remove non-aromatics and polar impurities in heavy aromatics through pore size sieving and polar adsorption. At the same time, during cleaning, the upper splicing part 3 can be lifted by the drive cylinder 6 to disassemble the middle splicing part 2, and the purification component 5 in the middle splicing part 2 can be disassembled and cleaned. It is also convenient to quickly replace the purification component 5.
