Description

Technical Field

[0001] This utility model relates to the field of chemical separation technology, and more specifically, to a separator. Background Technology

[0002] Liquid-liquid separators are crucial separation devices in chemical, petroleum, and pharmaceutical industries, primarily achieving efficient separation of liquids with different densities through the principle of gravity settling. Traditional separators typically rely on a fixed overflow weir or manual adjustment mechanism to control the interface position. While structurally simple, they suffer from significant drawbacks: firstly, interface height adjustment requires external screw or handwheel drive, leading to cumbersome operation and low adjustment accuracy; secondly, the sealing structure between the overflow weir and the shell is prone to leakage due to long-term friction, affecting separation stability. Furthermore, the inflow method of the mixed liquid has a significant impact on the separation effect—if the inflow velocity is too high or unevenly distributed, turbulence can easily occur, disrupting liquid layer stability and causing cross-entrainment of light and heavy phases, thus reducing separation efficiency.

[0003] In existing technologies, some improved separators attempt to optimize interface control through adjustable overflow weirs or inclined plate structures, but they still face problems such as complex structures and high maintenance costs. For example, interface mechanisms using screw adjustment require frequent maintenance of the sealing packing and are difficult to adjust in real time during equipment operation; while static distributors, due to fixed through-holes, cannot adapt to different flow conditions, easily causing excessively high local flow velocities and exacerbating liquid layer disturbance. In addition, traditional separators lack closed-loop control of the mixed liquid inflow rate, making it difficult to dynamically balance interference factors in the separation process, resulting in large fluctuations in separation performance.

[0004] To address the aforementioned issues, there is an urgent need to develop a separator with a simplified structure, flexible adjustment, and strong resistance to disturbances. An ideal solution should enable rapid and precise adjustment of the interface height during operation, while dynamically controlling the inflow velocity and distribution of the mixed liquid to minimize turbulence generation, thereby improving separation efficiency and stability. Furthermore, the equipment must balance reliable sealing with ease of operation to reduce maintenance costs and extend service life. Utility Model Content

[0005] The problem this invention addresses is: how to minimize turbulence generation by dynamically controlling the inflow velocity and distribution of the mixed liquid.

[0006] To solve the above problems, this utility model provides a separator, including a separator container and a mixture inlet pipe. The mixture inlet pipe is vertically inserted into the separator container and connected to a mixture distributor via a flange. The separator also includes a pneumatic drive system, which includes a connecting pipe, a tee pipe, a gas pipe, and a sealing pipe.

[0007] The first port of the three-way pipe is connected to the connecting pipe, the other end of the connecting pipe is connected to the external air pump, and the second port of the three-way pipe is connected to the gas pipe.

[0008] The sealing tube is installed on the mixture distributor, and an adjusting sleeve is movably sleeved inside it. The end of the adjusting sleeve is provided with a piston.

[0009] The gas pipeline is connected to the sealing pipe. When gas is injected into the sealing pipe, it drives the piston to move, causing the adjusting sleeve to move axially along the mixture distributor.

[0010] Both the adjusting sleeve and the mixture distributor are provided with through holes, and the injection speed of the mixture is controlled by adjusting the overlap of the through holes of the two.

[0011] A flow rate sensor is installed in the inlet pipe of the mixture to adjust the gas injection amount based on the liquid flow rate feedback, so as to reduce the disturbance of the mixture inflow to the stratification process.

[0012] In an optional embodiment, the third port of the three-way pipe is connected to a pressure balancing pipeline, and the gas pipeline and the pressure balancing pipeline are respectively equipped with a second solenoid valve and a first solenoid valve, which are used to switch the airflow direction to control the displacement of the regulating sleeve or accelerate the discharge of heavy phase.

[0013] In an optional embodiment, a light phase drainage assembly is further included, which includes a light phase discharge pipe, a float, and a telescopic pipe. The float is fixed to the top of the telescopic pipe, the telescopic pipe is movable along the height direction of the light phase discharge pipe, and a sealing ring is provided on the contact surface between the two. A light phase inlet is provided on the telescopic pipe.

[0014] In an optional embodiment, the stratified container is provided with a heavy phase drain port on its periphery, and the heavy phase drain port maintains stable internal pressure of the stratified container through a gas-liquid communication pipe.

[0015] In an optional embodiment, the through holes of the adjusting sleeve are multiple sets of equally spaced circular holes, and the shape of the through holes of the mixture distributor matches the through holes of the adjusting sleeve.

[0016] In an optional embodiment, the pneumatic drive system further includes a pressure regulating valve for dynamically adjusting the gas pressure value of the gas pipeline based on the signal from the flow rate sensor.

[0017] In an optional embodiment, the density of the float is less than the density of the light phase liquid, so that the telescopic tube automatically adjusts the height of the light phase inlet as the liquid level rises and falls.

[0018] In an optional embodiment, the through holes of the mixture distributor are spirally distributed along its axial direction.

[0019] In an optional embodiment, a guide groove is provided between the sealing tube and the adjusting sleeve to restrict the adjusting sleeve to move only axially.

[0020] In an optional embodiment, the first and second solenoid valves are proportional valves used to continuously adjust the gas flow rate according to a control signal.

[0021] Compared with the prior art, the layerer of this utility model has the following beneficial effects:

[0022] In this invention, the pneumatic drive system connects to an air pump via a three-way pipe. The gas pipeline leads to a sealed pipe, driving the adjusting sleeve to move axially, changing its alignment with the through-hole of the liquid distributor, thereby regulating the liquid injection rate. A flow rate sensor is installed inside the liquid inlet pipe; based on flow rate feedback, the gas injection volume is adjusted for dynamic control. This system also reduces disturbance to the stratification process caused by the liquid inflow, avoids localized turbulence, improves stratification efficiency, and can adapt to the separation requirements of liquids with different viscosities, thus enhancing its adaptability.

[0032] like Figure 1 and Figure 3 As shown, this utility model embodiment provides a layerer, including a layering container 700 and a mixture inlet pipe 400. The mixture inlet pipe 400 is vertically inserted into the layering container 700 and connected to the mixture distributor 500 through a flange. The layerer also includes a pneumatic drive system, which includes a connecting pipe 120, a tee pipe 130, a gas pipe 140, and a sealing pipe 160.

[0033] The first port of the tee pipe 130 is connected to the connecting pipe 120, the other end of the connecting pipe 120 is connected to an external air pump, and the second port of the tee pipe 130 is connected to the gas pipe 140.

[0034] A sealing tube 160 is installed on the mixture distributor 500, and an adjusting sleeve 170 is movably sleeved inside it. A piston 180 is provided at the end of the adjusting sleeve 170.

[0035] The gas line 140 is connected to the sealing tube 160. When gas is injected into the sealing tube 160, the piston 180 is driven to move, causing the adjusting sleeve 170 to move axially along the mixture distributor 500.

[0036] Both the adjusting sleeve 170 and the mixing liquid distributor 500 are provided with through holes, and the mixing liquid injection speed is controlled by adjusting the overlap of the through holes of the two.

[0037] A flow rate sensor is installed inside the mixture inlet pipe 400 to adjust the gas injection rate based on the liquid flow rate feedback, so as to reduce the disturbance of the mixture inflow to the stratification process.

[0038] In this embodiment, the pneumatic drive system is connected to an air pump via a three-way pipe 130, and a gas pipeline 140 leads into a sealing pipe 160, driving the adjusting sleeve 170 to move axially, changing its overlap with the through-hole of the mixture distributor 500, thereby adjusting the mixture injection speed. A flow rate sensor is installed inside the mixture inlet pipe 400, adjusting the gas injection volume based on flow rate feedback to achieve dynamic control. This also reduces the disturbance of the mixture inflow to the stratification process, avoids local turbulence, and improves stratification efficiency. Furthermore, it can adapt to the separation requirements of liquids with different viscosities, improving adaptability.

[0039] The third port of the three-way pipe 130 is connected to a pressure balancing pipe. The gas pipe 140 and the pressure balancing pipe are respectively equipped with a second solenoid valve 150 and a first solenoid valve 110, which are used to switch the airflow direction to control the displacement of the regulating sleeve 170 or accelerate the discharge of heavy phase.

[0040] The third port of the three-way pipe 130 is connected to the pressure balancing pipeline. The gas pipeline 140 and the pressure balancing pipeline are respectively equipped with a second solenoid valve 150 and a first solenoid valve 110, which can switch the airflow direction. The airflow can be flexibly controlled by opening and closing the solenoid valves, which can both adjust the injection speed of the mixed liquid and accelerate the discharge of heavy phase, thereby improving the separation efficiency.

[0041] like Figure 2 As shown, it also includes a light phase drainage assembly 300, which includes a light phase discharge pipe 330, a float 310 and a telescopic pipe 320. The float 310 is fixed to the top of the telescopic pipe 320, and the telescopic pipe 320 can move along the height direction of the light phase discharge pipe 330. The contact surface between the two is provided with a sealing ring, and a light phase inlet 321 is opened on the telescopic pipe 320.

[0042] The float 310 floats with the light phase liquid surface, ensuring that the light phase liquid is always discharged from the optimal position, automatically adapting to changes in liquid level, preventing the light phase from mixing with the heavy phase, and improving separation purity.

[0043] The stratification container 700 is provided with a heavy phase drain port 600 on its periphery. The heavy phase drain port 600 maintains stable internal pressure in the stratification container through a gas-liquid connecting pipe 200. The gas-liquid connecting pipe is used to stabilize the internal pressure of the container and prevent pressure fluctuations from affecting the stratification effect.

[0044] In this embodiment, the through holes of the adjusting sleeve 170 are multiple sets of equally spaced circular holes, and the shape of the through holes of the mixture distributor 500 matches that of the adjusting sleeve 170. The alignment of the through holes can be precisely controlled to adapt to different flow rate requirements, thereby improving the accuracy of flow rate regulation. At the same time, it can reduce liquid jet disturbance, make the mixture evenly distributed, and improve the stratification stability.

[0045] It should be noted that, as an alternative, the through-holes of the mixture distributor 500 are spirally distributed along its axial direction. This can further enhance the uniformity of liquid distribution, reduce local turbulence, and improve the quality of stratification.

[0046] The pneumatic drive system also includes a pressure regulating valve for dynamically adjusting the pressure value of the gas line 140 based on the signal from the flow rate sensor.

[0047] The gas pressure in the gas pipeline 140 is dynamically adjusted based on the flow rate sensor signal to achieve closed-loop control, automatically optimize the injection speed of the mixed liquid, and improve separation efficiency.

[0048] The density of the float 310 is less than that of the lighter phase liquid, allowing the telescopic pipe 320 to automatically adjust the height of the lighter phase inlet 321 as the liquid level rises and falls. This improved adaptability, making it suitable for separating lighter phase liquids of varying densities.

[0049] A guide groove is provided between the sealing tube 160 and the adjusting sleeve 170 to limit the adjusting sleeve 170 to move only axially. This improves adjustment stability and prevents misalignment of the through hole caused by sleeve displacement.

[0050] The first solenoid valve 110 and the second solenoid valve 150 are proportional valves used to continuously adjust the gas flow rate according to the control signal. By using proportional valves, more precise control can be achieved, adjustment accuracy can be improved, and the separation process can be optimized. This also reduces airflow impact and avoids pressure fluctuations caused by sudden valve opening and closing.

[0051] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
