Description

Technical Field

[0001] The utility model relates to the technical field of petroleum resins, and particularly relates to a distillation device for petroleum resin production and processing. Background Technique

[0002] Petroleum resin (hydrocarbon resin) is a thermoplastic resin produced by by-products C5 and C9 fractions from petroleum cracking through processes such as pretreatment, polymerization, and distillation. It is not a high polymer but an oligomer with a molecular weight between 300 - 3000. Petroleum resin gets its name because its source is petroleum derivatives. It has characteristics such as low acid value, good miscibility, water resistance, ethanol resistance, and chemical resistance, is chemically stable to acids and bases, and has the characteristics of adjusting viscosity and good thermal stability. Petroleum resin is generally not used alone but is used together with other resins as a promoter, regulator, modifier, etc. Petroleum resin can generally be classified into four forms of products: C5 aliphatic, C9 aromatic, DCPD (cycloaliphatic), and pure monomers such as poly SM, AMS (alpha methyl styrene), etc. Its constituent molecules are all hydrocarbons, so it is also called hydrocarbon resin (hydrocarbon resins, HCR). Petroleum resin is divided into aliphatic resin (C5), cycloaliphatic resin (DCPD), aromatic resin (C9), aliphatic / aromatic copolymer resin (C5 / C9), and hydrogenated petroleum resin according to different raw materials. C5 hydrogenated petroleum resin, C9 hydrogenated petroleum resin. Petroleum resin is a newly developed chemical product in recent years. Due to its advantages such as low price, good miscibility, low melting point, water resistance, ethanol resistance, and chemical resistance, it can be widely used in various industries and fields such as rubber, adhesives, coatings, papermaking, and inks.

[0003] In the field of petrochemical industry, the distillation of petroleum resin is a common production process. However, after the distillation operation is completed, a large amount of petroleum resin attachments often remain inside the equipment.

The right side of the adjustable discharge pipe 84 penetrates to the inside of the cold water tank 7 and is communicated with a U-shaped pipe 85. The lower end of the U-shaped pipe 85 penetrates to the right side of the cold water tank 7.

[0025] As a technical optimization scheme of the present invention, through the setting of the distillation component 8, more convenient distillation operation can be carried out on the petroleum resin, avoiding the situation that the heat of the petroleum resin in the distillation tank 3 is unevenly distributed, resulting in a reduction in the working efficiency of the distillation operation of the petroleum resin.

[0026] Referring to Figure 2The cleaning component 9 includes a high-pressure water pump 91. The input end of the high-pressure water pump 91 is connected to a water inlet pipe 92. The lower end of the water inlet pipe 92 is connected to the bottom of the rear side of the cold water tank 7. The output end of the high-pressure water pump 91 is connected to a water spray pipe 93 through a three-way valve. The lower end of the water spray pipe 93 passes through the interior of the distillation tank 3 and is connected to a spray ball 94. There are two spray balls 94. The left side of the bottom of the distillation tank 3 is connected to an adjustable water outlet pipe 95. The lower end of the adjustable water outlet pipe 95 is connected to the top of the right side of the sewage tank 6.

[0027] As a technical optimization scheme of the utility model, by setting the cleaning component 9, the inner wall of the rectifier tube can be cleaned after the distillation operation is completed, so as to prevent the residual attachments on the inner wall of the distillation tank 3 from being mixed into the subsequent production process and contaminating the newly produced petroleum resin product, resulting in reduced product purity, deterioration of color, and unstable performance.

[0028] refer to Figure 5 The left and right sides of the surface of the U-shaped tube 85 are fixedly connected with fixing blocks 10 , and the fixing blocks 10 are fixedly connected to the inner wall of the cold water tank 7 .

Open the adjustable water outlet pipe 95, and the sewage generated during the operation of the cleaning component 9 inside the distillation tank 3 enters the interior of the sewage tank 6, achieving the effect of efficient cleaning.
