[0028] The following will be combined with the drawings in the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a secondary impurity removal device for alkylation raw materials, comprising a barrel body 1, a feed pipe 2 is fixedly connected to one side of the top surface of the barrel body 1, a plurality of heating pipes 3 are fixedly connected to the top surface of the inner wall of the barrel body 1, a water collecting bucket 4 is fixedly connected to the bottom of the inner wall of the barrel body 1, a collecting pipe 5 is fixedly connected to the bottom of the water collecting bucket 4, a drainage pipe 6 is fixedly connected to the bottom of one side of the collecting pipe 5, the drainage pipe 6 runs through the barrel body 1, a heating wire 7 is arranged on the outer side of the collecting pipe 5, a plurality of guide grooves 8 are opened on the top surface of the water collecting bucket 4, and an extraction component is arranged on one side of the top surface of the barrel body 1.

[0030] When the alkylation feedstock enters the barrel 1, the heating tube 3 and the heating wire 7 are driven to heat the alkylation feedstock to reduce the viscosity of the alkylation feedstock. At this time, the density difference between water and the alkylation feedstock is used to make the alkylation feedstock float to the inner top of the barrel 1, and the water sinks to the inside of the collecting tube 5, thereby achieving the purpose of oil-water separation. In the process of water sinking, the slope of the water collecting bucket 4 can guide the water along the water collecting bucket 4 into the collecting tube 5. At the same time, the water can be further guided by the guide groove 8. By increasing the temperature of the alkylation feedstock, the viscosity of the alkylation feedstock can be reduced, the density difference between oil and water is increased, and the sedimentation of water is helpful, thereby improving the efficiency and quality of water removal.

[0031] Reference Figure 1 and Figure 2 The bottom of the barrel body 1 is fixedly connected with a support leg 9. A valve 10 is provided at one end of the drainage pipe 6. The barrel body 1 can be supported by the support leg 9, and the separated water can be discharged from the drainage pipe 6 by opening the valve 10.

[0032] Reference Figure 1 and Figure 2A temperature sensor is fixedly connected to the middle of one side of the inner wall of the barrel body 1, and the barrel body 1, the water collecting bucket 4 and the collecting pipe 5 are all set to colorless and transparent materials. Multiple heating pipes 3 and multiple guide grooves 8 are distributed in a star array with the central axis of the barrel body 1 as the center. The temperature sensor can detect the temperature of the alkylation raw material to avoid the denaturation of the alkylation raw material due to excessive temperature.

[0033] Reference Figure 1 and Figure 2 The extraction assembly includes a delivery pump 11 and a water inlet pipe 12. The delivery pump 11 is fixedly connected to one side of the top surface of the barrel body 1, and the water inlet pipe 12 is fixedly connected to the input end of the delivery pump 11. The water inlet pipe 12 passes through the top of the barrel body 1, and the bottom of the water inlet pipe 12 is above the top surface of the water collecting bucket 4. The separated alkylation raw material can be extracted by driving the delivery pump 11.

[0034] Reference Figure 1 and Figure 4 A through hole 13 is provided at the bottom of the feed pipe 2, and one side of the feed pipe 2 is fixedly connected to the top of one side of the inner wall of the barrel body 1. When the alkylation raw material enters the feed pipe 2, since the bottom of the feed pipe 2 is sealed by the inner wall of the barrel body 1, the alkylation raw material will flow out from the through hole 13 and flow down along the inner wall of the barrel body 1, which can prevent the alkylation raw material from colliding with the alkylation raw material at the bottom of the barrel body 1 during the falling process, thereby causing the alkylation raw material to move more rapidly and mix with water.

[0035] Working principle: When in use, first pour the alkylation raw material into the barrel body 1 along the feed pipe 2. When the alkylation raw material enters the feed pipe 2, since the bottom of the feed pipe 2 is sealed by the inner wall of the barrel body 1, the alkylation raw material will flow out from the through hole 13 and flow down along the inner wall of the barrel body 1, which can avoid the alkylation raw material in the falling process from colliding with the alkylation raw material at the bottom of the barrel body 1, thereby causing the alkylation raw material to move more rapidly and mix with water. When the alkylation raw material enters the barrel body 1, the alkylation raw material will accumulate on the water collecting bucket 4. At this time, by driving the heating tube 3 and the heating wire 7, the heating tube 3 can be used to heat the alkylation raw material above the water collecting bucket 4, and the heating wire 7 can be used to heat the alkylation raw material at the bottom of the water collecting bucket 4. The alkylation raw material inside the collecting pipe 5 is heated. The viscosity of the alkylation raw material can be reduced by heating the alkylation raw material. At this time, the density difference between water and the alkylation raw material can be used to make the alkylation raw material float to the inner top of the barrel 1, while the water sinks to the inside of the collecting pipe 5, thereby achieving the purpose of oil-water separation. In the process of water sinking, the water can be guided along the water collecting bucket 4 into the collecting pipe 5 through the slope of the water collecting bucket 4. At the same time, the water can be further guided by the guide groove 8, so it is beneficial to collect the water. When the separation is completed, the alkylation raw material in the upper layer can be extracted by driving the delivery pump 11, and then the water can be discharged from the drainage pipe 6 by opening the valve 10.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
