Technical Field

[0001] This utility model relates to the field of PSI production technology, and in particular to a high-temperature tubular chain reactor for PSI production. Background Technology

[0002] A high-temperature tubular chain reactor is an industrial device that integrates a tubular structure with high-temperature reaction characteristics, primarily used in chemical reaction scenarios requiring efficient heat transfer and continuous processes. While PSI production requires the use of a high-temperature tubular chain reactor, existing technologies for PSI production cannot move materials during operation, resulting in uneven mixing and susceptibility to high-temperature foaming of raw materials, significantly extending reaction time and reducing reaction and operational efficiency. Therefore, we propose a high-temperature tubular chain reactor for PSI production. Utility Model Content

[0003] The purpose of this invention is to solve at least one of the technical problems existing in the prior art, and to provide a high-temperature tubular chain reactor for PSI production, which can force the material to move by the tubular chain, resulting in more uniform reaction and mixing, and is not afraid of high-temperature foaming of raw materials, and the reaction time is greatly shortened.

[0004] To achieve the above objectives, a high-temperature tubular chain reactor for PSI production is provided, comprising: a tubular chain body, wherein a heat transfer oil inlet is connected to the top of the tubular chain body near the left side, and a heat transfer oil outlet is connected to the top of the tubular chain body near the left side, and a feed valve is connected to the top of the tubular chain body near the heat transfer oil inlet.

[0005] According to the high-temperature tubular chain reactor for PSI production, a circulating water inlet is connected to the bottom of the tubular chain near the left side, and a circulating water outlet is connected to the top of the tubular chain near the heat transfer oil outlet.

[0006] According to the high-temperature tubular chain reactor for PSI production, a transmission device is provided near the left side of the tubular chain body, and a PSI outlet is connected to the bottom of the tubular chain body near the circulating water inlet.

[0007] According to the high-temperature tubular chain reactor for PSI production, the heat transfer oil outlet and the circulating water outlet are arranged on the left and right sides at the top of the tubular chain body.

[0008] According to the high-temperature tubular chain reactor for PSI production, the PSI outlet and the circulating water inlet are located on the left and right sides at the bottom of the tubular chain body.

[0009] The above solution has at least one of the following beneficial effects:

[0010] 1. Enables continuous production;

[0011] 2. The material is forced to move by the tubular chain, resulting in more uniform reaction and mixing. It is also not afraid of high-temperature foaming of raw materials, and the reaction time is greatly shortened.

[0012] 3. The use of tubular chain heating reduces the equipment's footprint;

[0013] 4. Adopting a fully enclosed design prevents oxygen from entering, avoids product oxidation, and improves product yield.

[0022] Reference Figures 1 to 3 This utility model provides a high-temperature tubular chain reactor for PSI production, which includes a tubular chain body 1. A heat transfer oil inlet 6 is connected to the top of the tubular chain body 1 near the left side, and a heat transfer oil outlet 7 is connected to the top of the tubular chain body 1 near the left side. A feed valve 5 is connected to the top of the tubular chain body 1 near the heat transfer oil inlet 6.

[0023] The bottom of the tubular chain body 1, near the left side, is connected to a circulating water inlet 2, and the top of the tubular chain body 1, near the heat transfer oil outlet 7, is connected to a circulating water outlet 8. The heat transfer oil outlet 7 and the circulating water outlet 8 are positioned on opposite sides of the top of the tubular chain body 1. This structure enables continuous production, and the forced movement of materials by the tubular chain body 1 results in more uniform mixing and is resistant to high-temperature foaming of raw materials, significantly shortening the reaction time.

[0024] A transmission device 4 is installed near the left side inside the tubular chain body 1, and a PSI outlet 3 is connected to the bottom of the tubular chain body 1 near the circulating water inlet 2. The PSI outlet 3 and the circulating water inlet 2 are located on the left and right sides of the bottom of the tubular chain body 1. With this structure, the tubular chain heating system occupies less space, and the fully enclosed design prevents oxygen from entering, avoids product oxidation, and improves product yield.

[0025] Working principle: When using this technical solution, first turn on the tubular chain body 1, set the speed, and introduce heat transfer oil to heat the system. When the temperature inside the system reaches 230℃, add the appropriate amount of maleic anhydride and urea mixture through the feeding valve 5. The material reacts at high temperature through the tubular chain body 1. The material reacts fully and continues to follow the tubular chain body 1 to the cooling zone, where it is continuously cooled. Then, the material is discharged and the feeding cycle continues.
