Description

Technical Field

[0001] This utility model relates to the field of chemical impurity separation technology, and in particular to a heated separation tank, which is a device for separating and removing salts contained in oily chemicals. Background Technology

[0002] In the production and processing of chemicals, especially in the field of oily chemicals, the purity of the product often directly affects its performance and the quality of subsequent processing. However, during the preparation, storage, or transportation of oily chemicals, some impurities inevitably become mixed in, among which salt is a common type of impurity. The presence of these salts not only reduces the purity of oily chemicals but may also adversely affect their chemical properties, physical stability, and effectiveness.

[0003] Traditional methods for separating salts from oily chemicals include distillation, extraction, and crystallization. However, these methods suffer from low efficiency, complex operation, or high cost when dealing with salt impurities in certain types of oily chemicals. The limitations of traditional methods are particularly evident when the salt content of the oily chemicals is low, but extremely high product purity is required, such as for high-end chemicals with high purity requirements, like 1,1-phenyltetrahydronaphthylethane. Utility Model Content

[0004] The technical problem this invention aims to solve is that traditional methods for separating salts from oily chemicals, including distillation, extraction, and crystallization, suffer from low efficiency, complex operation, and high cost.

[0005] To address the aforementioned problems, this utility model provides a heated separation tank for separating salts from oily liquid chemicals, comprising: a tank body and heating elements.

[0006] The heating separation tank provided by this utility model is used to separate and remove salt from salty oily chemicals. An oil-water mixture is added to the heating separation tank of this utility model so that the salt dissolves in the water. In order to prevent the oily chemicals from solidifying, the oil-water mixture is heated to promote the dissolution of salt in the water. After standing and stratification, the oil and water are separated, thus realizing the separation of salt from oily chemicals.

[0007] To promote the heating and stratification of oil and water and facilitate the discharge of stratified products, as one option for the above-mentioned tank structure, the middle and upper parts of the tank are columnar cavities, the lower part of the tank is a conical cavity, the bottom surface of the conical cavity is connected to the columnar cavity, and the apex of the conical cavity is the discharge port of the tank.

[0008] In order to improve the heating efficiency of the heating element on the oil layer, as one option for the arrangement of the first heating element described above, the first heating element is arranged in a bent shape inside the cavity of the tank.

[0009] In order to improve the uniformity and heating efficiency of the heating element on the lower layer of water, as one option for the above-mentioned second heating element arrangement of this utility model, the second heating element is arranged around the wall of the tank.

[0010] Optionally, the heating element includes at least one of an electric heating wire, a heat exchange tube, and a heating jacket.

[0011] Preferably, the heating element is an electric heating wire.

[0012] To facilitate the control of the first heating element and the second heating element, as one option for the connection method of the heating elements, the first heating element and the second heating element are connected in parallel.

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0021] This invention provides a heated separation tank, aiming to solve the problems of low efficiency, complex operation, and high cost in traditional salt separation methods for oily chemicals. The specific embodiments of this invention will be described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, this utility model provides an embodiment of a heated separation tank, which is suitable for separating salts from oily liquid chemicals.

[0023] The heated separation tank mainly consists of a tank body 1 and a heating element 3. The tank body 1 serves as the container for the entire separation process, and its top is equipped with a feed inlet 11 for adding a salt-containing oil-water mixture into the tank body 1. The bottom of the tank body 1 is equipped with a discharge outlet 12, which is fitted with a valve 2 to control the discharge of the separated oily chemicals and water containing dissolved oil and salt after the separation is completed.

[0024] Heating element 3 is disposed on tank 1 and is used to heat the oil-water mixture in tank 1. Specifically, heating element 3 includes a first heating element 31 located in the upper part of tank 1 and a second heating element 32 located in the lower part of tank 1, which can ensure that the oil-water mixture in tank 1 is heated evenly in both the upper and lower regions, thereby more effectively promoting the dissolution of salt in water.

[0025] Preferably, the heating separation tank is further equipped with an oil-water mixing device 4, which is connected to the feed inlet 11.

[0026] Before use, sufficient water is added to the salty oily chemicals using the oil-water mixing device 4 and thoroughly mixed to dissolve the salt in the water, forming a salty oil-water mixture. Then, the salty oil-water mixture is added to the tank 1 through the inlet 11. Next, the heating element 3 is activated to heat the oil-water mixture. During heating, the salt gradually dissolves in the water, while the oily chemicals do not easily solidify due to the heating effect. After heating for a period of time, the oil-water mixture settles and separates into layers in the tank 1. Because oil is less dense than water, it gradually floats to the top, while the salt water sinks to the bottom. After settling and separating, the valve 2 at the outlet 12 is opened to first remove the lower layer of salt water, then remove the oily chemicals, thus achieving the separation and removal of salt from the oily chemicals.

[0027] This invention's heating separation tank effectively improves the separation efficiency of salts in oily chemicals through heating and static stratification, simplifies the operation process, and reduces costs. Furthermore, the partitioned arrangement of the heating element 3 ensures more uniform heating, further enhancing the separation effect.

[0028] Continue to refer to Figure 1 In some preferred embodiments, the middle and upper parts of the tank 1 are columnar cavities, the lower part of the tank 1 is a conical cavity, the bottom surface of the conical cavity is connected to the columnar cavity, and the apex of the conical cavity is the discharge port 12 of the tank 1.

[0029] Specifically, the middle and upper parts of tank 1 are cylindrical cavities, facilitating the addition of the oil-water mixture and subsequent heating and settling processes. The lower part of tank 1 is a conical cavity, with its bottom surface connecting to the cylindrical cavity, forming a continuous cavity structure. The apex of the conical cavity is the outlet 12 of tank 1, which allows the brine to be discharged more smoothly through the outlet 12 after settling and stratification. The shape of the conical cavity helps to accelerate the convergence of fluid towards the outlet, improving discharge efficiency. On the other hand, the conical bottom reduces the accumulation of residues, facilitating cleaning and maintenance of the tank.

[0030] Continue to refer to Figure 1 In some preferred embodiments, the second heating element 32 is disposed around the wall of the tank 1. The second heating element 32's surrounding placement around the tank wall, and the fact that the second heating element 32 is located at the bottom, and the bottom portion is a conical cavity, helps to ensure that the temperature of the lower water layer is higher than the temperature of the upper oil layer. Since heat flows from low to high, bottom heating also heats the oil in the middle and upper portions.

[0031] Continue to refer to Figure 1In some preferred embodiments, the first heating element 31 is arranged in a bent shape inside the cavity of the tank 1. By placing the first heating element 31 inside the tank cavity, the heating element can directly heat the oil-water mixture or the oil, improving heating efficiency. This helps accelerate the salt dissolution process while reducing localized overheating or cooling caused by uneven temperature, thereby improving separation efficiency.

[0032] In some embodiments, the heating element 3 includes at least one of an electric heating wire, a heat exchange tube, and a heating jacket. Specifically, the heating element 3 may include at least one type of electric heating wire, heat exchange tube, and heating jacket.

[0033] Electric heating wires are a common and efficient heating element that directly heats the oil-water mixture in a tank using heat generated by an electric current. Electric heating wires offer advantages such as rapid heating, good temperature control, and ease of installation and maintenance. In the heating separation tank of this invention, the electric heating wires can be flexibly arranged in different positions within the tank, such as inside the cavity or around the tank wall, to achieve uniform heating and efficient separation.

[0034] Heat exchange tubes are another effective heating element that utilizes the heat released when a fluid (such as water or steam) flows inside the tube to heat the oil-water mixture in the tank. Heat exchange tubes offer advantages such as uniform heating, high thermal efficiency, and wide applicability. In the heating separation tank of this invention, the heat exchange tubes can be arranged at the bottom or side wall of the tank, and heating is achieved through fluid circulation provided by an external heat source.

[0035] Reference Figure 2 The heating jacket heats the tank walls by heating the fluid (such as water, steam, or heat transfer oil) within the jacket, thereby heating the substances inside the tank. This structure has advantages such as uniform heating, low heat loss, and convenient maintenance.

[0036] In one embodiment, preferably, referring to Figure 2 The first heating element 31 serves as an electric heating wire or heat exchange tube, and the second heating element 32 serves as a heating jacket.

[0037] Continue to refer to Figure 1 The first heating element 31 and the second heating element 32 are connected in parallel. This parallel connection allows the first and second heating elements 31 to work independently or simultaneously as needed, enabling the heating process to be adjusted according to different operating conditions and separation requirements, thus improving the adaptability and ease of operation of the equipment. Since the first heating element 31 is located inside the cavity of the tank 1, it directly heats the oil-water mixture, while the second heating element 32 is arranged around the tank wall to supplement the heating of the mixture in the lower part of the tank. The parallel connection of the heating elements allows for adjustment of power and heating time according to actual needs, avoiding unnecessary energy waste.

[0038] In summary, this utility model provides a heated separation tank for separating and removing salt from salty oily chemicals. An oil-water mixture is added to the heated separation tank, allowing the salt to dissolve in the water. To prevent the oily chemicals from solidifying, the oil-water mixture is heated to promote the dissolution of salt in the water. After settling and stratification, the oil and water are separated, thus achieving the separation of salt from oily chemicals.
