Description

Technical Field

[0001] This utility model belongs to the field of anthracene oil fraction filtration technology, specifically relating to an anthracene oil fraction slag discharge and dehydration device. Background Technology

[0002] Anthracene oil fraction is an important byproduct of the needle coke industry. Visually, it is a yellowish-green oily liquid that crystallizes at room temperature. These crystals are yellow and emit blue fluorescence, exhibiting unique optical characteristics. Anthracene oil fraction displays certain solubility characteristics; it is insoluble in water but partially soluble in organic solvents such as hot benzene and chlorobenzene. This solubility characteristic plays a crucial role in its subsequent separation, purification, and application. Its main components include anthracene, phenanthrene, carbazole, acenaphthene, and other polycyclic aromatic hydrocarbons. These complex organic compounds endow anthracene oil fraction with a wide range of applications.

[0003] Impurities and moisture in anthracene oil fractions can affect their quality in many ways. Chemically, impurities may trigger side reactions or occupy reaction sites, reducing the reactivity of the main components. Moisture not only dilutes the active ingredients but may also cause water-sensitive reactions to produce byproducts. Both impurities and moisture reduce chemical stability. Physically, impurities and moisture alter boiling point and distillation range, increase viscosity, affect fluidity, and lower flash point, increasing safety risks. In terms of product quality, impurities reduce the content of active ingredients, and moisture dilutes the product concentration; both are detrimental to improving product purity. They also interfere with the crystallization process, affecting crystallization speed and morphology, thus reducing the quality and yield of crude and refined anthracene products.

[0004] Patent application number 20192231517.1 discloses a device for efficiently removing ash from anthracene oil-asphalt mixtures. This device employs a two-stage filtration system consisting of a specially designed cylindrical filter and a special disc filter, supplemented by a constant-temperature filtration device and a precise flow control device. This successfully and stably controls the ash content in the anthracene oil-asphalt mixture to below 15 ppm, with an optimal level below 10 ppm, providing conditions for the preparation of high-performance carbon fibers. However, in existing technologies, during continuous filtration, impurities gradually accumulate on the filter element surface, leading to pore size reduction and decreased filtration throughput, thus affecting production efficiency. Furthermore, the filter element is prone to clogging and requires frequent replacement. Utility Model Content

[0005] Based on the above-mentioned technical problems, the purpose of this utility model is to provide an anthracene oil fraction slag discharge and dehydration device. This device uses a baffle plate assembly, a slag discharge port assembly, an anthracene oil fraction distribution mechanism, and a water absorption filter element in synergy to effectively remove solid impurities and moisture from the anthracene oil fraction, while avoiding clogging, thereby improving the quality of the anthracene oil fraction.

[0006] The specific technical solution is as follows:

[0007] An anthracene oil fraction slag discharge and dehydration device includes a tank body with an anthracene oil fraction inlet and a discharge pipe. It also includes: an anthracene oil fraction inlet baffle, a baffle assembly, a slag discharge port assembly, an anthracene oil fraction distribution mechanism, a water-absorbing filter element, and a detachable bottom plate. The anthracene oil fraction inlet baffle is embedded in the tank body and positioned opposite the anthracene oil fraction inlet. The baffle assembly is embedded in the tank body and includes an upper baffle, a middle baffle, and a lower baffle. The slag discharge port assembly is respectively located at the low liquid levels of the upper, middle, and lower baffles. The anthracene oil fraction distribution mechanism is embedded in the tank body. The water-absorbing filter element is located below the anthracene oil fraction distribution mechanism. The detachable bottom plate is installed between the tank body and the discharge pipe.

[0008] In addition, the anthracene oil fraction slag discharge and dehydration tank provided by this utility model may also have the following additional technical features:

[0009] In the above technical solution, the slag discharge port assembly includes: an upper slag discharge port, a middle slag discharge port, and a lower slag discharge port; the upper slag discharge port, the middle slag discharge port, and the lower slag discharge port are respectively located at the low liquid level of the upper baffle plate, the middle baffle plate, and the lower baffle plate, and each of the upper slag discharge port, the middle slag discharge port, and the lower slag discharge port is equipped with a slag discharge valve.

[0010] In the above technical solution, the anthracene oil fraction distribution mechanism includes: a dividing plate, a diversion groove, and a through hole; the dividing plate is embedded in the tank body, and the dividing plate is provided with a through hole and a diversion groove.

[0011] In the above technical solution, the bottom of the anthracene oil fraction inlet baffle is higher than the highest point of the upper baffle.

[0014] In the above technical solution, an outlet valve is provided at the discharge pipe.

[0015] The anthracene oil fraction slag discharge and dehydration device of this utility model has the following advantages compared with the prior art:

[0016] 1. After impurities are effectively separated and discharged through multi-layer baffles and slag discharge ports, the anthracene oil fraction distribution mechanism and water-absorbing filter element are used in combination to ensure that the anthracene oil fraction can pass through the water-absorbing filter element more evenly, thereby effectively removing solid impurities and water from the anthracene oil fraction, avoiding clogging, and thus improving the quality of the anthracene oil fraction.

[0017] 2. The design of the multi-layer baffle and slag discharge port allows the anthracene oil fraction to undergo multiple turns within the tank, which helps larger particles of impurities settle and effectively discharges the settled impurities through the slag discharge ports set at the low liquid level of each layer.

[0018] 3. The anthracene oil fraction distribution mechanism ensures that the anthracene oil fraction is evenly dispersed before entering the water-absorbing filter element, avoiding the problem of low filtration efficiency caused by excessive or insufficient local flow. After the anthracene oil fraction is separated from large particles of impurities, the water-absorbing filter element removes the moisture and residual small impurities from the anthracene oil fraction, thereby improving the filtration effect.

Detailed Implementation

[0023] The following are specific implementation cases and appendices. Figure 1-2 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0024] An anthracene oil fraction slag dehydration device, such as Figure 1-2 As shown, the system includes a tank body 10, on which anthracene oil fraction inlet 11 and discharge pipe 12 are provided. It also includes: anthracene oil fraction inlet baffle 13, a baffle assembly, a slag discharge port assembly, anthracene oil fraction distribution mechanism, a water-absorbing filter element 17, and a detachable bottom plate 18. The anthracene oil fraction inlet baffle 13 is embedded within the tank body 10 and is positioned opposite to the anthracene oil fraction inlet 11. The baffle assembly is embedded within the tank body 10 and includes an upper baffle 14, a middle baffle 15, and a lower baffle 16. The slag discharge port assembly is respectively located at the low liquid level of the upper baffle 14, the middle baffle 15, and the lower baffle 16. The anthracene oil fraction distribution mechanism is embedded within the tank body 10. The water-absorbing filter element 17 is located below the anthracene oil fraction distribution mechanism. The detachable bottom plate 18 is installed between the tank body 10 and the discharge pipe 12.

[0025] With the above structure, the anthracene oil fraction enters the tank 10 through the anthracene oil fraction inlet 11. The anthracene oil fraction inlet baffle 13 guides the anthracene oil fraction, causing it to fall onto the upper baffle 14. During the flow, the anthracene oil fraction flows sequentially through the upper baffle 14, the middle baffle 15, and the lower baffle 16. During this flow, the anthracene oil fraction settles solid impurities at the low liquid levels of the upper baffle 14, the middle baffle 15, and the lower baffle 16, respectively. This achieves a three-stage sedimentation effect on the impurities in the anthracene oil fraction, thereby improving the removal effect of solid impurities from the anthracene oil fraction. The solid impurities on the upper baffle 14, the middle baffle 15, and the lower baffle 16 can be discharged through the slag discharge port. After slag discharge, the anthracene oil fraction is diverted through the anthracene oil fraction distribution mechanism, so that the anthracene oil fraction can pass evenly through the water-absorbing filter element 17, thereby effectively removing solid impurities and water from the anthracene oil fraction, avoiding clogging, and thus improving the quality of the anthracene oil fraction.

[0026] Specifically, the design of the multi-layer baffles and slag discharge ports allows the anthracene oil fraction to undergo multiple turns within the tank 10, which helps larger particles of impurities settle and effectively discharges the settled impurities through the slag discharge ports set at the low liquid level of each layer.

[0027] Specifically, the anthracene oil fraction distribution mechanism ensures that the anthracene oil fraction is evenly dispersed before entering the water-absorbing filter element 17, avoiding the problem of low filtration efficiency caused by excessive or insufficient local flow. After the anthracene oil fraction is separated by large particles of impurities, the water-absorbing filter element 17 removes the moisture and residual small impurities from the anthracene oil fraction, thereby improving the filtration effect.

[0028] Specifically, the anthracene oil fraction entering tank 10 reaches a temperature of about 100 degrees Celsius. The anthracene oil fraction is then extracted from the oil collection tank by an anthracene oil fraction pump. At this time, the temperature of the anthracene oil fraction is 330 degrees Celsius, which is a high temperature. After multiple cooling steps, such as heat exchange with refined asphalt and heat exchange with circulating water, the temperature is gradually reduced to about 100 degrees Celsius before being sent into this device for slag discharge and dehydration.

[0029] Specifically, the detachable base plate 18 is connected to the discharge pipe 12, and the detachable base plate 18 is connected to the tank body 10 by bolts. This structure facilitates the replacement of the internal water absorption filter element 17.

[0030] Specifically, the inside of the water-absorbing filter element 17 is filled with water-absorbing resin.

[0031] Specifically, the baffle plate consists of an inclined plate and a vertical plate.

[0032] In embodiments of this utility model, such as Figure 1As shown, the slag discharge port assembly includes: an upper slag discharge port 19, a middle slag discharge port 20, and a lower slag discharge port 21; the upper slag discharge port 19, the middle slag discharge port 20, and the lower slag discharge port 21 are respectively located at the low liquid level of the upper baffle plate 14, the middle baffle plate 15, and the lower baffle plate 16, and slag discharge valves 22 are respectively provided at the upper slag discharge port 19, the middle slag discharge port 20, and the lower slag discharge port 21.

[0033] The upper slag discharge port 19, the middle slag discharge port 20, and the lower slag discharge port 21 are respectively set at the low liquid level of the upper baffle plate 14, the middle baffle plate 15, and the lower baffle plate 16 to discharge impurities on the baffle plates. Furthermore, by setting the slag discharge valve 22, the impurities are discharged after the slag discharge and dehydration operation of the anthracene oil fraction is completed, thereby preventing the anthracene oil fraction from being discharged from the slag discharge port.

[0034] In embodiments of this utility model, such as Figure 2 As shown, the anthracene oil fraction distribution mechanism includes: a dividing plate 23, a diversion groove 24, and a through hole 25; the dividing plate 23 is embedded in the tank body 10, and the dividing plate 23 is provided with a through hole 25 and a diversion groove 24.

[0035] By setting the diversion groove 24 and the through hole 25 on the distribution plate, the diversion groove 24 can divert the anthracene oil fraction, making it evenly distributed, and the through hole 25 can disperse the anthracene oil fraction to the water absorption filter element 17, thereby preventing the anthracene oil fraction from accumulating in one place.

[0036] Specifically, the diameter of the through hole 25 is 15mm.

[0037] In an embodiment of this utility model, the bottom of the anthracene oil fraction inlet baffle 13 is higher than the highest point of the upper baffle 14.

[0038] In embodiments of this utility model, the inclination angles of the upper baffle 14, the middle baffle 15, and the lower baffle 16 are 60-80°.

[0039] In an embodiment of this utility model, the bottom of the vertical surface of the upper baffle 14 is higher than the highest point of the middle baffle 15, and the bottom of the vertical surface of the middle baffle 15 is higher than the highest point of the lower baffle 16.

[0040] The baffles are tilted at an angle of 60-80° to concentrate the solid impurities that settle in the anthracene oil fraction, thus facilitating their discharge from the slag outlet. Furthermore, the vertical design of the baffles helps the anthracene oil fraction flow vertically, preventing liquid splashing.

[0041] Specifically, the bottom of the vertical surface of the upper baffle 14 is higher than the highest point of the middle baffle 15, which means that the vertical surface of the upper baffle 14 is higher than the liquid surface of the anthracene oil fraction located in the middle baffle 15, thereby preventing the anthracene oil fraction from excessively disturbing the liquid surface during the falling process, thus affecting the settling effect.

[0042] In an embodiment of this utility model, an outlet valve 26 is provided at the discharge pipe 12.

[0043] Implementation process: Using the above structure, anthracene oil fraction enters the tank 10 through anthracene oil fraction inlet 11. Anthracene oil fraction inlet baffle 13 guides the anthracene oil fraction, causing it to fall onto the upper baffle 14. During the flow, the anthracene oil fraction flows sequentially through the upper baffle 14, the middle baffle 15, and the lower baffle 16. During this flow, solid impurities are deposited at the low liquid levels of the upper baffle 14, the middle baffle 15, and the lower baffle 16, respectively. This achieves a three-stage precipitation effect on the impurities in the anthracene oil fraction, thereby improving the removal effect of solid impurities. The solid impurities on the upper baffle 14, the middle baffle 15, and the lower baffle 16 can be discharged through the slag discharge port. After slag discharge, the anthracene oil fraction is diverted through the anthracene oil fraction distribution mechanism, so that the anthracene oil fraction can pass evenly through the water-absorbing filter element 17, thereby effectively removing solid impurities and water from the anthracene oil fraction, avoiding clogging, and thus improving the quality of the anthracene oil fraction.
