Abstract
Description
Technical Field
[0001] This utility model relates to the field of C5 petroleum resin production technology, and in particular to a circulating solvent recovery device for C5 petroleum resin production. Background Technology
[0002] C5 petroleum resin is a low-molecular-weight resin produced during petroleum cracking. It is mainly composed of olefin compounds with 5 carbon atoms and is commonly used as an additive in products such as rubber, paint, adhesives, and printing inks. It has good adhesion, high temperature resistance, and chemical stability. In the production process of C5 petroleum resin, solvents are usually required to help dissolve and polymerize the resin. These solvents become waste or by-products in the production process after the reaction. Therefore, in order to improve production efficiency and reduce solvent consumption and environmental pollution, a circulating solvent recovery device is usually used in the production process.
[0003] However, most existing methods for recovering circulating solvents in C5 petroleum resin production involve direct filtration or distillation. Filtration often uses a single method, resulting in poor filtration efficiency, and distillation fails to quickly condense and recover the vapor, leading to low practicality. Therefore, those skilled in the art have provided a circulating solvent recovery device for C5 petroleum resin production to address the problems mentioned in the background. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a circulating solvent recovery device for the production of C5 petroleum resin, which solves the problems mentioned in the background section.

A cooling box is also provided on one side of the processing box. One end of the air inlet pipe is connected to a conduction box inside the cooling box. A first baffle and a second baffle are respectively provided inside the conduction box from top to bottom. A drain pipe is connected to one side of the cooling box through the outer side of the conduction box. A water inlet pipe and a water outlet pipe are also provided on one side of the cooling box from top to bottom.
[0006] As a further technical solution of this utility model, the air inlet pipe is configured as a "U" shaped pipe, and the radius of the air inlet pipe is larger than the radius of the drain pipe.
[0007] As a further technical solution of this utility model, the first baffle is installed on the left inner side of the conduction box, and the second baffle is installed on the right inner side of the conduction box.
[0008] As a further technical solution of this utility model, the material of the adsorption mesh is activated carbon, and the material of the treatment membrane is an ultrafiltration membrane.

[0011] This invention provides a circulating solvent recovery device for the production of C5 petroleum resin, which has the following advantages compared with the prior art: 1. This design relates to a circulating solvent recovery device for the production of C5 petroleum resin. By setting up an adsorption mesh and a treatment membrane inside the treatment tank, the circulating solvent for the production of C5 petroleum resin will be adsorbed and filtered when it enters the treatment tank, thus facilitating subsequent distillation. At the same time, the operation of the stirring motor will cause the stirring rod outside the rotating shaft to stir the solution inside the treatment tank, improving the efficiency of subsequent heating and distillation recovery. It has good practicality.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-3 This utility model provides a technical solution for a circulating solvent recovery device for C5 petroleum resin production: it includes a processing tank 1 and a feed pipe 11 set on the upper surface of the processing tank 1. A stirring motor 3 is set at the middle position of the upper surface of the processing tank 1. The driving end of the stirring motor 3 is connected to a rotating shaft 31. Stirring rods 32 are symmetrically arranged on the outer side of the rotating shaft 31. A partition 12 is also set inside the processing tank 1. An adsorption net 14 and a treatment membrane 13 are respectively set on one side of the partition 12 from top to bottom. A heating base plate 2 is set on the lower surface of the processing tank 1. The circulating solvent for C5 petroleum resin production entering the processing tank 1 can be adsorbed and treated by the adsorption net 14. At the same time, the treatment membrane 13 can improve its filtration effect. The heating base plate 2 can heat the solvent inside the processing tank 1 to recover the steam generated by its distillation. An air inlet pipe 44 is provided through the upper surface of the processing box 1. A cooling box 4 is also provided on one side of the processing box 1. One end of the air inlet pipe 44 is connected to a conduction box 45 inside the cooling box 4. A first baffle 46 and a second baffle 47 are respectively provided inside the conduction box 45 from top to bottom. A drain pipe 43 is connected to one side of the cooling box 4 through the outer side of the conduction box 45. A water inlet pipe 41 and a drain pipe 42 are also provided on one side of the cooling box 4 from top to bottom. Cold water can be introduced into the cooling box 4 through the water inlet pipe 41, and steam can be introduced into the conduction box 45 through the air inlet pipe 44 for deflection and condensation recovery.
[0017] like Figure 1 As shown, the air inlet pipe 44 is a "U" shaped pipe, and the radius of the air inlet pipe 44 is larger than the radius of the drain pipe 43. Steam can enter the interior of the conduction box 45 through the air inlet pipe 44, and after condensation, the liquid will be discharged out through the drain pipe 43.
[0018] like Figure 3 As shown, the first baffle 46 is installed on the left inner side of the conduction box 45, and the second baffle 47 is installed on the right inner side of the conduction box 45. The first baffle 46 and the second baffle 47 can deflect the steam entering the conduction box 45, thereby reducing the steam flow rate and enabling better condensation and recovery of the steam.
[0019] like Figure 2 As shown, the material of the adsorption mesh 14 is activated carbon, and the material of the treatment membrane 13 is an ultrafiltration membrane. The adsorption mesh 14 can adsorb and treat the circulating solvent used in the production of C5 petroleum resin that enters the treatment box 1, while the treatment membrane 13 can improve its filtration effect.
[0020] like Figure 1 As shown, a heating tungsten wire is spirally arranged inside the heating base plate 2. The heating tungsten wire can be heated by an external power source, and the heat generated will be transferred to the interior of the processing box 1 to heat the solvent and generate steam, so as to facilitate subsequent condensation and recovery.
[0021] like Figure 2 As shown, there are two sets of cylindrical stirring rods 32 symmetrically arranged on the outside of the rotating shaft 31. The operation of the stirring motor 3 will cause the rotating shaft 31 to rotate, and the stirring rods 32 can stir and mix the solution inside the treatment tank 1, thereby improving the efficiency of the steam generated by heating.
[0022] The working principle of this utility model is as follows: When using the circulating solvent recovery device for C5 petroleum resin production, the circulating solvent to be recovered for C5 petroleum resin production enters the processing tank 1 through the feed pipe 11. After entering, the feed pipe 11 is closed. When the solvent enters, it will pass through the adsorption net 14 and the processing membrane 13 in sequence. Through the purpose of double filtration and adsorption, impurities in the solvent can be filtered out before entering the processing tank 1. After entering, the heating base plate 2 is heated by an external power source. The heat will heat the solvent inside the processing tank 1 to generate steam. At the same time, when heating, the stirring motor 3 is started to work, so that the stirring rod 32 outside the rotating shaft 31 can stir the solvent inside, thereby improving the steam generation efficiency. The generated steam enters the conduction box 45 inside the cooling box 4 through the air inlet pipe 44. After entering, the steam is deflected by the first baffle 46 and the second baffle 47, which reduces the steam flow rate and allows the steam to condense efficiently inside the conduction box 45. Cold water is introduced into the cooling box 4 through the water inlet pipe 41, and the water is discharged out through the drain pipe 42. Valves are installed on the outside of both the water inlet pipe 41 and the drain pipe 42. The condensed solution is discharged out through the drain pipe 43 to achieve its recycling purpose.
[0023] All electrical devices used in this invention are existing and known, and are connected to an external main controller and power supply. The main controller can be a conventional and known device such as a computer, and can be purchased and used directly on the market. Its structure, circuit and control principle are all existing and known technologies. Therefore, the structure, circuit and control principle of the device are not described in detail here.
[0024] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
