Description

Technical Field

[0001] This invention relates to an oil-water impurity separation and treatment device, and more specifically, to an oil-water impurity separation and treatment device for petrochemical machinery, belonging to the field of petrochemicals. Background Technology

[0002] In the petrochemical production process, a lot of oil-water impurity mixtures are obtained. The oil-water impurity mixture is separated into an oil-water mixture. After further oil-water separation and extraction, a portion of the petroleum can be recovered.

[0003] The general procedure for removing impurities from oil-water mixtures is as follows: the oil-water mixture containing impurities is transported to a settling tank and left to stand for a period of time until the impurities settle to the bottom of the tank. Then, the oil-water mixture is pumped away from the top. While this method can separate heavier impurities, impurities lighter than the oil-water mixture cannot be removed and will be pumped away with the mixture, causing inconvenience for subsequent processing. In addition, because the oil-water mixture has a certain viscosity, the entire settling process is time-consuming, and the impurities settled at the bottom of the tank are difficult to clean, making it both time-consuming and labor-intensive.

[0004] In summary, it is necessary to propose an oil-water impurity separation and treatment device for petrochemical machinery to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, this invention provides an oil-water impurity separation and treatment device for petrochemical machinery, which features the ability to simultaneously separate light and heavy impurities in an oil-water mixture, short separation time, and easy cleaning of the separated impurities.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0007] A petrochemical machinery oil-water impurity separation and treatment device includes an impurity removal tank and a settling tank. An inclined frame is fixedly installed at the bottom of the impurity removal tank. A trapezoidal groove is provided inside the impurity removal tank. The inclined side of the trapezoidal groove on the right side is in contact with the inclined surface of the inclined frame. The top of the trapezoidal groove is open. The four sides of the trapezoidal groove are respectively located near the four inner walls of the impurity removal tank. A top cover is provided at the top of the impurity removal tank, and a motor is installed on the top cover. The motor is connected to a telescopic shaft. One end of the telescopic shaft extends into the impurity removal tank and is connected to a filter plate. The filter plate corresponds vertically to the top opening of the trapezoidal groove and is adapted to the size of the top opening. The filter plate has several evenly distributed filter holes. An inlet and an outlet are respectively provided at the upper and lower ends near the side walls of the impurity removal tank. The outlet is connected to the settling tank via a liquid pump. The inlet pipe of the liquid pump is connected to the outlet, and the outlet pipe of the liquid pump is connected to the interior of the settling tank.

[0008] Preferably, an oil suction machine is installed on the top of the settling tank, and the oil suction machine is connected to the oil drain pipe.

[0009] Preferably, a filter screen is installed inside the liquid outlet.

[0010] Preferably, both the impurity removal tank and the settling tank are rectangular structures, with the settling tank located on one side of the impurity removal tank and the liquid pump fixed to the outer wall of the impurity removal tank.

[0011] Preferably, the upper half of the front and rear sidewalls of the trapezoidal groove are both configured as a hollowed-out mesh structure.

[0012] Preferably, a sealing door is provided on the side wall of the impurity removal tank that can be opened and closed, and a detachable baffle door is provided on the left side wall of the trapezoidal groove, with the baffle door facing the sealing door.

[0013] Preferably, the liquid inlet is connected to a valve.

[0014] Preferably, the liquid outlet is connected to multiple liquid pumps, and each liquid pump is connected to a settling tank.

[0015] Beneficial effects: By installing a filter plate that can move up and down in the impurity removal tank, light and heavy impurities in the oil-water mixture in the impurity removal tank can be filtered and pressed down into the trapezoidal groove at the bottom. The separation method is simple, time-saving, and has good separation effect. The sealing door on the side wall of the impurity removal tank and the baffle door on the trapezoidal groove can facilitate the cleaning of impurities in the trapezoidal groove after the impurity removal is completed.

Detailed Implementation

[0019] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, what is described is only a part of this invention, and not all of it. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0020] The technical problem to be solved by this invention is: when removing impurities from oil-water mixtures, light impurities cannot be removed by their own sedimentation, the sedimentation process is time-consuming, and impurities at the bottom of the tank are difficult to clean. Therefore, an oil-water impurity separation and treatment device for petrochemical machinery is proposed.

[0021] Specific examples Figure 1-2 The illustration shows a specific embodiment of an oil-water impurity separation and treatment device for petrochemical machinery. This embodiment includes a removal tank 1 and a settling tank 2. An inclined frame 3 is fixedly installed at the bottom of the removal tank 1. A trapezoidal groove 4 is provided inside the removal tank 1. The inclined side of the trapezoidal groove 4 on its right side is in contact with the inclined surface of the inclined frame 3. The top of the trapezoidal groove 4 is open. The four sides of the trapezoidal groove 4 are respectively located close to the four inner walls of the removal tank 1. A top cover 5 is provided at the upper end of the removal tank 1, and a motor 6 is installed on the top cover 5. The motor 6 is connected to a telescopic shaft 7. One end of the telescopic shaft 7 extends into the impurity removal tank 1 and is connected to a filter plate 8. The filter plate 8 corresponds vertically to the top opening of the trapezoidal groove 4 and is adapted to the size of the top opening of the trapezoidal groove 4. The filter plate 8 has a number of evenly distributed filter holes 19. The upper and lower ends near the side wall of the impurity removal tank 1 are respectively provided with a liquid inlet 9 and a liquid outlet 10. The liquid outlet 10 is connected to a settling tank 2 through a liquid pump 11. The liquid inlet pipe 15 of the liquid pump 11 is connected to the liquid outlet 10, and the liquid outlet pipe 16 of the liquid pump 11 is connected to the inside of the settling tank 2.

[0022] The processing flow using the technical solution of this application is as follows: The oil-water mixture is connected to the inlet 9 of the impurity removal tank 1 through the discharge pipe and enters the impurity removal tank 1. At this time, the filter plate 8 is located at the top of the impurity removal tank 1, higher than the inlet 9. The oil-water mixture entering from the inlet 9 falls into the impurity removal tank 1. After filling the impurity removal tank 1 to about two-thirds of its height, the valve on the inlet 9 is closed to stop the liquid from entering. The motor 6 is started, driving the filter plate 8 to move down. The oil and water are filtered through the filter holes 19, while the light and heavy impurities are directly filtered and pressed down into the trapezoidal tank 4. At this time, the position of the filter plate 8 is lower than the outlet 10. Then, the liquid pump 11 is started to pump the filtered oil-water mixture to the settling tank 2 for settling. After a period of time, the upper layer of oil can be separated by the oil suction machine 12 and sent to the next process. Alternatively, the oil mixture can be directly extracted and sent to the refining tank for refining. In order to improve the processing efficiency, one impurity removal tank 1 can be used with multiple settling tanks 2. After the impurity removal is completed, the sealing door 17 can be opened and the trapezoidal groove 4 can be pulled out for impurity cleaning. If there are few impurities, the trapezoidal groove 4 can be opened directly from the sealing door 17 to open the barrier door 18 of the trapezoidal groove 4 for cleaning without pulling it out.

[0023] In a preferred embodiment, an oil suction machine 12 is installed on the top of the settling tank 2. The oil suction machine 12 is connected to the oil drain pipe 13. The oil suction machine 12 is an industrial oil suction machine, and its specifications and models can be selected as needed.

[0024] In a preferred embodiment, a filter screen 14 is installed inside the liquid outlet 10 to perform filtration and improve work efficiency.

[0025] In a preferred embodiment, both the impurity removal tank 1 and the settling tank 2 are rectangular structures, with the settling tank 2 located on one side of the impurity removal tank 1, and the liquid pump 11 fixed to the outer wall of the impurity removal tank 1.

[0026] In a preferred embodiment, the upper half of the front and rear sidewalls of the trapezoidal groove 4 are both configured with a perforated mesh structure. The function of the perforated structure is as follows: after the filter plate is pressed into the trapezoidal groove, it will be pressed down to the position below the mesh structure. Liquid is filtered out from the filter holes of the filter plate 8. To reduce the resistance during filtration, that is, to reduce the resistance when the filter plate 8 is pressed down, the upper half of both sides of the trapezoidal groove 4 is configured with a mesh structure. When the filter plate 8 is pressed down, the filtrate can also be filtered out from the mesh structure of the trapezoidal groove 4. This facilitates more thorough solid-liquid separation when light and heavy impurities are filtered and pressed down into the trapezoidal groove 4. The fully enclosed lower half contributes to the structural strength of the trapezoidal groove.

[0027] In a preferred embodiment, a sealing door 17 is provided on the side wall of the impurity removal tank 1, which can be opened and closed, and a detachable baffle door 18 is provided on the left side wall of the trapezoidal groove 4, with the baffle door 18 facing the sealing door 17.

[0028] In a preferred embodiment, the inlet 9 is connected to a valve to facilitate control of the input of the oil-water mixture.

[0029] In a preferred embodiment, the liquid outlet 10 is connected to multiple liquid pumps 11, and each liquid pump 11 is connected to a settling tank 2, which is highly practical and flexible.

[0030] Finally, it should be noted that the present invention is not limited to the above embodiments, and many variations are possible. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of the present invention should be considered within the scope of protection of the present invention.
