Traditional tar removal methods rely on manual retrieval, which is inefficient and labor-intensive. In recent years, automatic tar removal equipment has gradually replaced manual operation. Its core principle is to extract and separate the tar from the mother liquor using an oil floater. However, due to fluctuations in solution density, existing oil floaters cannot completely collect all the oil. Utility Model Content

[0021] It should be noted that this application is mainly applicable to the process of purifying coke oven gas, where sulfuric acid or phosphoric acid is commonly used to absorb ammonia from the gas. In this application scenario, when the absorbent circulates in the ammonia absorption tower and the mother liquor circulation tank, tar and coal dust in the gas are washed off and transferred to the mother liquor circulation tank.
[0022] like Figure 1 As shown, the oil spill collector includes a float 100, a connecting plate 200, a liquid inlet / outlet 300, and a counterweight plate 400. The float 100 is a hollow shell, and at least three floats 100 are provided. There are two sets of connecting plates 200, which are respectively provided at the top and bottom of the float 100. The liquid inlet / outlet 300 is a hollow structure with openings at both ends. The liquid inlet / outlet 300 passes through the connecting plate at the bottom of the float 100, and the bottom end of the liquid inlet / outlet 300 is suitable for connecting a suction pump. The counterweight plate 400 is a circular plate structure and is provided on the liquid inlet / outlet. The connecting plate 200 includes a first connecting plate 210 and a second connecting plate 220; the first connecting plate 210 extends outward to a plurality of first connecting ends, which are connected to the top of the float 100 and the distance between two adjacent first connecting ends is the same; the second connecting plate 220 extends outward to a plurality of second connecting ends, which are connected to the bottom of the float 100 and the distance between two adjacent second connecting ends is the same.
[0023] Specifically, such as Figure 1As shown, the specific structure of the oil spill collector includes a float 100, a connecting plate 200, a liquid inlet / outlet 300, and a counterweight plate 400. Firstly, the floats 100 are designed to float on the liquid surface, so the floats 100 need to be hollow. Furthermore, to ensure the overall structure remains stable on the liquid surface, according to this embodiment (but not limited to this embodiment), four floats 100 are provided. To connect the four floats 100 together, two connecting plates 200 are provided, one at the top of the float and the other at the bottom. The four floats 100 are connected together via the connecting plates 200. Therefore, the connecting plates 200 include a first connecting plate 210 and a second connecting plate 220. To connect with the floats 100, the first connecting plate 210 extends outwards with multiple first connecting ends, which connect to the top of the floats 100. The second connecting plate 220 extends outwards with multiple second connecting ends, which connect to the bottom of the floats 100. According to this embodiment, but not limited to this embodiment, the number of floats 100 is four, and the number of first and second connecting ends is also four, forming a cross structure with the first connecting plate 210 and the second connecting plate 220, which is more stable. To collect floating oil, a liquid inlet / outlet 300 is provided. One end of the liquid inlet / outlet 300 is connected to a suction pump, which draws the floating oil from the liquid inlet / outlet 300. To enable the liquid inlet / outlet 300 to adapt to fluctuations in solution density and changes in liquid level, the oil-collecting part of the liquid inlet / outlet 300 is designed as an inverted trapezoidal cylinder structure. Multiple serrated weir structures are evenly arranged on the outer periphery of the top of the oil-collecting part. To cope with fluctuations in solution density, the addition or removal of the counterweight plate 400 and the threaded structure of the liquid inlet / outlet 300 can adjust the position of the oil-collecting part 300 on the liquid surface, allowing it to be used in solutions of different densities. This design enables the entire system to collect floating oil even with different solution densities and liquid levels.
[0024] In one possible implementation, the liquid inlet / outlet 300 includes an oil collection section 310 and a connecting pipe 320; the oil collection section 310 is an inverted trapezoidal cylindrical structure, and multiple sawtooth weir structures are evenly arranged on the outer periphery of the top of the oil collection section 310; the connecting pipe 320 is connected to the bottom of the oil collection section 310, and the bottom of the connecting pipe 320 is suitable for connecting a suction pump.
[0025] Specifically, such as Figure 2As shown, the specific structure of the liquid inlet / outlet component 300 includes an oil collection section 310 and a connecting pipe 320. The bottom of the oil collection section 310 is connected to the connecting pipe 320. The diameter of the cross-sectional circle of the connecting pipe 320 is smaller than the inlet diameter of the oil collection section 310. Therefore, the shape of the oil collection section 310 is a trapezoidal cylindrical structure. In order to prevent the oil collection section 310 from being completely submerged and to optimize the oil suction effect, the top of the oil collection section 310, which is the inlet of the floating oil, is set as a sawtooth weir structure. This setting can also reduce the inlet flow fluctuation and ensure the flow rate of the suction pump is stable.
[0026] In one possible implementation, the top of the connecting pipe 320 passes through the center of the second connecting plate 220, and the oil collecting part 310 is located above the second connecting plate 220. This arrangement is because the second connecting plate 220 is located at the bottom of the float 100. When the float 100 floats on the liquid surface, the second connecting plate 220 is located below the liquid surface. By adding or removing the counterweight plate 400 and adjusting the threads of the inlet / outlet part 300, the liquid surface is positioned between the top and bottom of the serrated weir of the oil collecting part 310, allowing the oil collecting part 310 to continuously collect floating oil.
[0027] In one possible implementation, multiple counterweight plates 400 are provided, each counterweight plate 400 has a through hole in its center, through which the connecting pipe 320 can pass, and the counterweight plate 400 is fixed to the bottom of the second connecting plate 220 by bolts.
[0028] Specifically, such as Figure 2 As shown, the counterweight plate has a through hole at its center with a diameter larger than that of the connecting pipe 320. This design allows the connecting pipe 320 to pass through the counterweight plate 400. The counterweight plate 400 is then fixed to the bottom of the second connecting plate 220 by bolts. This design allows the number of counterweight plates 400 to be increased according to actual needs, making the entire device more adaptable and practical.
[0029] In one possible implementation, a rotating lifting ring 500 and an anchor chain 510 are also included; the rotating lifting ring 500 is located at the center of the first connecting plate 210; the anchor chain 510 has a preset length, the bottom end of the anchor chain 510 is connected to the rotating lifting ring 500, and the top end of the anchor chain 510 is adapted to connect to a preset position inside the manhole at the top of the mother liquor circulation tank.
[0030] Specifically, such as Figure 1 As shown, in order to adapt to changes in liquid level and to the environment of strong flow, a rotating lifting ring 500 and an anchor chain 510 are used. The rotating lifting ring 500 is located at the center of the first connecting plate 210, allowing the entire structure to rotate freely. The anchor chain 510 is designed to allow the entire device to move with changes in liquid level, ensuring the stability of the working area.
[0031] In one possible implementation, an upper nut 321 and a lower nut 322 are also included; the upper nut 321 and the lower nut 322 are disposed on the threaded pipe between the oil receiving part 310 and the connecting pipe 320, with the upper nut 321 located on the upper part of the second connecting plate 220 and the lower nut 322 located on the lower part of the second connecting plate 220. This arrangement can be used to fix the liquid inlet / outlet 300 and adjust the height of the liquid inlet / outlet 300.
[0032] In one possible implementation, a conical top cover 110 is provided on the top of the float 100, and a first connecting end is connected between the float 100 and the top cover 110. This arrangement can increase the overall buoyancy, and the conical top cover 110 can prevent a large amount of tar from adhering to the top of the float 100 due to violent solution flow, thus preventing an increase in the overall weight of the equipment and affecting the oil suction effect, and also increasing the line of sight for operators to observe the oil collection section.
[0033] In one possible implementation, the number of first connecting ends is the same as the number of floats 100, and the number of second connecting ends is the same as the number of first connecting ends.
[0034] In one possible implementation, the float 100, top cover 110, second connecting plate 220, and oil collection part 310 are made of 316L stainless steel, and the inner and outer surfaces of the float 100, top cover 110, second connecting plate 220, and oil collection part 310 are coated with polytetrafluoroethylene. This arrangement effectively prevents tar adhesion and extends the equipment's lifespan.
[0035] Through the above-mentioned configuration, the entire device can not only adapt to changes in liquid level and environments with violent flow, but also to fluctuations in solution density, thus optimizing the oil absorption effect and solving the technical problem that existing oil floaters cannot fully collect oil due to fluctuations in solution density.
[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
