DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] Figures 1 to 5 This is an embodiment of the utility model.

[0021] Example 1

[0022] A scaling device comprises a tank body 1 and a tank cover 2, wherein the top of the tank body 1 is detachably connected to the tank cover 2, a supporting leg 3 is fixedly installed at the bottom of the tank body 1, a scaling field 4 is arranged inside the tank body 1, a partition 5 is arranged outside the scaling field 4, the partition 5 divides the inside of the tank body 1 into an upper drainage area 7 and a lower liquid inlet area 6, a tank inlet 8, a tank outlet 9 and a cleaning port 10 are arranged on the tank body 1, the tank outlet 9 and the cleaning port 10 are communicated with the drainage area 7 of the tank body 1, the tank inlet 8 is communicated with the liquid inlet area 6 of the tank body 1, a slag discharge port 11 is arranged on the bottom surface of the tank body 1, a water inlet pipe 12 is arranged on the tank body 1, the water inlet pipe 12 passes through the outer wall of the tank body 1 and is communicated with the bottom of the scaling field 4, and a water outlet pipe 13 is arranged on the tank cover 2, the water outlet pipe 13 passes through the outer wall of the tank cover 2 and is communicated with the top of the scaling field 4. After the utility model is arranged on the pipeline for conveying oil, the oil first enters the liquid inlet area 6 of the tank body 1, then passes through the scaling field 4 and enters the liquid discharge area 7 of the tank body 1, and finally is discharged into the pipeline again through the tank outlet 9 and conveyed to the subsequent system equipment. The oil will scale and deposit when passing through the scaling field 4. The scaling field 4 can be cleaned by adding a cleaning agent through the cleaning port 10, so that the scale in the manifold can be effectively treated. In addition to scaling, there will also be wax in the scaling field 4. Hot water can be introduced into the scaling field 4 through the provided water inlet pipe 12 and the water outlet pipe 13 to increase the temperature, so that the wax in the scaling field 4 is melted, thereby enhancing the cleaning effect of the scaling field 4.

[0023] Example 2

[0024] On the basis of Example 1, the scaling field 4 includes a box body 401 and a plurality of array tubes 402, wherein the plurality of array tubes 402 are obliquely arranged inside the box body 401, and both ends of the array tubes 402 penetrate the top and bottom of the box body 401, and a corrugated structure with an uneven surface is arranged on the inner wall of the array tubes 402, and the top and bottom of the box body 401 are respectively connected to the outlet pipe 13 and the inlet pipe 12. The array tubes 402 penetrating the box body 401 can transport the oil in the liquid inlet area 6 to the liquid discharge area 7, and the oil can complete scaling and be deposited in the array tubes 402 when passing through the array tubes 402 due to the arrangement of the inner wall of the array tubes 402.

[0025] Furthermore, the inclination angle of the tube array 402 is set to 60°. In this way, when the oil passes through the tube array 402 , the sedimentation time of the scale particles after scaling is shorter than the residence time, ensuring that the scale can stay in the tube array 402 .

[0026] Example 3

[0027] On the basis of Example 2, a support ring 15 is fixedly installed on the inner wall of the tank body 1, and the support ring 15 is fixedly connected to the partition 5. The support ring 15 is specifically used to be fixedly connected to the partition 5, which can improve the installation efficiency of the scaling field 4 and ensure that the liquid inlet area 6 and the liquid discharge area 7 are completely separated.

[0028] Furthermore, a sealing ring is provided on the contact surface between the support ring 15 and the partition plate 5. After the partition plate 5 and the support ring 15 are fixedly connected, the sealing ring can prevent the oil in the liquid inlet area 6 and the liquid discharge area 7 from leaking into each other.

[0029] Example 4

[0030] On the basis of Example 3, a main safety valve interface 16 is provided on the tank cover 2, and an auxiliary safety valve interface 17 is provided at the bottom of the tank body 1. Safety valves are provided on the main safety valve interface 16 and the auxiliary safety valve interface 17 to improve the safety performance of the utility model and prevent the tank body 1 from being deformed or even exploded due to excessive pressure in the tank body 1.

[0031] Example 5

[0032] On the basis of Example 4, a lifting lug 14 is fixedly installed on the top of the tank cover 2 and the partition 5. After the lifting lug 14 is provided, it is convenient to carry the tank cover 2 and the scaling field 4 using tools.

[0033] Working principle: When in use, the oil in the pipeline enters the liquid inlet area 6 of the tank body 1 from the tank inlet 8, and then the oil enters the discharge area 7 of the tank body 1 through the array tube 402. The oil finally re-enters the pipeline from the tank outlet 9 and is transported to the subsequent system equipment. The oil will scale, wax and deposit when passing through the array tube 402. Then, when cleaning, the oil must be prevented from entering the tank body 1. A cleaning agent is added to the tank body 1 through the cleaning port 10 to complete the cleaning of the inner wall of the array tube 402. The slag cleaned from the array tube 402 is discharged from the slag discharge port. Hot water can also be input into the interior of the box body 401 through the water inlet pipe 12 and the water outlet pipe 13 and circulated to heat the array tube 402 to melt the wax on the inner wall of the array tube 402, and at the same time, it is discharged from the slag discharge port with the slag to enhance the cleaning effect.
