Description

Technical Field

[0001] This utility model relates to the field of separation tank technology, and in particular to a separation tank. Background Technology

[0002] A gas-liquid separator is a core piece of equipment used to separate gas and liquid in a fluid.

[0003] For example, a patent with publication number CN213160148U, entitled "A Multifunctional Gas-Water Separator," was published on May 11, 2021. It includes a filter separation tank, a sealing cover, a pressure gauge, an inlet connecting pipe, an outlet connecting pipe, a sampleable gas-water separator assembly, a multifunctional filter frame assembly, a guide plate, a cyclone separator spiral blade, a support column, a reinforcing base, a discharge pipe, a guide groove, a protruding plate, a nameplate, and spring clips. In this invention, when gas containing moisture enters the lower part of the filter separation tank, it moves upward under gas pressure. Through the action of the guide plate and the cyclone separator spiral blade, the moisture falls into the lower part of the filter separation tank. However, the upward airflow easily carries liquid droplets from the side walls, reducing the separation efficiency. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to propose a separation tank to solve the problem of reduced separation efficiency.

[0005] Based on the above objectives, this utility model provides a separation tank, including a tank body. The upper end of the tank body is provided with an air outlet and a safety valve interface. The lower end of the tank body is provided with a drain outlet for draining water accumulated at the bottom of the tank body. A level gauge is connected to the lower part of the tank body. A tangential air inlet is provided on the side wall of the tank body, with the airflow direction tangential to the inner side wall of the tank body, causing the airflow to move in a circular motion along the inner wall of the tank body, generating centrifugal force to assist in the separation of large droplets. A flow guide is installed on the inner side wall of the tank body, located on one side of the air inlet. The flow guide includes a spirally upward horizontal flow guide plate, and a vertical flow guide plate is provided on the side of the horizontal flow guide plate facing the inner side wall of the tank body. The horizontal flow guide plate is connected to the inner side wall of the tank body via a support rod. The upper end of the vertical flow guide plate is connected to the side of the horizontal flow guide plate facing the inner side wall of the tank body. The distance between the vertical flow guide plate and the inner side wall of the tank body gradually decreases from top to bottom.

[0006] Optionally, filters are provided at both the air inlet and the air outlet.

[0007] Optionally, the filter screen is a double-layer nylon mesh filled with adsorbent particles.

[0008] Optionally, a mist eliminator is provided on the upper part of the tank, located below the air outlet.

[0009] Optionally, the drain outlet is located at the lowest position of the tank bottom, and the drain outlet is connected to a drain valve. A sewage outlet located on one side of the drain outlet is provided at the lower part of the tank.

[0010] Optionally, the tank body includes a cylindrical body, and the upper and lower ends of the cylindrical body are welded with end caps, which are used to close the ends of the cylindrical body to form a closed space.

[0011] The beneficial effects of this utility model are as follows: The separation tank provided by this utility model allows liquid-containing gas to enter the inlet tangentially and move in a high-speed circular motion along the inner wall of the tank, generating centrifugal force. The liquid droplets are thrown onto the side wall of the tank and slide down the tank wall under the action of gravity, falling into the settling zone at the bottom of the tank for preliminary gas-liquid separation. The horizontal guide plate facilitates the spiral upward guidance of the airflow, while the vertical guide plate helps to reduce the spiral upward airflow from re-entraining the liquid droplets on the side wall into the airflow. The downward tilt of the vertical guide plate helps to separate the airflow from the liquid droplets on the side wall of the tank, increasing the probability of liquid separation in the gas-liquid mixture, thereby improving the separation probability and separation efficiency. The arc-shaped inward lower surface of the vertical guide plate facilitates the inward guidance of the airflow, while the arc-shaped outward upper surface of the vertical guide plate facilitates the guidance of the liquid droplets.

[0017] like Figures 1 to 3 As shown, a separation tank includes a tank body 1. The upper end of the tank body 1 is provided with an air outlet 3 and a safety valve interface. The lower end of the tank body 1 is provided with a drain outlet 7 for draining water accumulated at the bottom of the tank body 1. A level gauge is connected to the lower part of the tank body 1 for real-time monitoring of the liquid level inside the tank body 1. A tangential air inlet 2 is provided on the side wall of the tank body 1. The airflow direction of the air inlet 2 is tangential to the inner side wall of the tank body 1, causing the airflow to move in a circular motion along the inner wall of the tank body 1, generating centrifugal force to assist in the separation of large droplets. A flow guide 4 is installed on the inner wall of the tank body 1, located on one side of the air inlet 2. The flow guide 4 includes a spirally upward horizontal flow guide 5. A vertical flow guide 6 is provided on the side of the horizontal flow guide 5 facing the inner wall of the tank body 1. The horizontal flow guide 5 is connected to the inner wall of the tank body 1 by a support rod. The upper end of the vertical flow guide 6 is connected to the side of the horizontal flow guide 5 facing the inner wall of the tank body 1. The distance between the vertical flow guide 6 and the inner wall of the tank body 1 gradually decreases from top to bottom.

[0018] Liquid gas enters tangentially into inlet 2 and moves at high speed in a circular motion along the inner wall of tank 1, generating centrifugal force. Liquid droplets are thrown against the side wall of tank 1 and, under gravity, slide down the wall and fall into the settling zone at the bottom of tank 1, undergoing initial gas-liquid separation. The horizontal guide plate 5 facilitates the spiral upward guidance of the airflow, while the vertical guide plate 6 helps to reduce the spiral upward airflow from re-entraining the droplets on the side wall into the airflow. The downward-sloping vertical guide plate 6 further separates the airflow from the tank. The droplets on the side wall of tank 1 increase the probability of liquid separation in the gas-liquid mixture, thereby improving the separation probability and efficiency. The lower surface of the vertical guide plate 6 with its arc shape facing inward facilitates the inward guidance of airflow, while the upper surface of the vertical guide plate 6 with its arc shape facing outward facilitates the guidance of droplets. As liquid gradually accumulates in the settling zone at the bottom of tank 1, when the liquid level gauge detects that the liquid level exceeds the upper limit, the drain valve at the drain port 7 at the bottom of tank 1 is automatically opened for liquid drainage. When the liquid level drops to the lower limit, the drain valve is closed to prevent gas from leaking from the drain port 7.

[0019] The safety valve interface is connected to a safety valve with a set pressure of 1.1 times the design pressure. It automatically releases pressure when overpressure occurs to prevent tank 1 from rupturing.

[0020] Both the air inlet 2 and the air outlet 3 are equipped with filters to filter impurities.

[0021] The filter screen is a double-layer nylon mesh filled with adsorption particles, which can be activated carbon particles.

[0022] A mist eliminator is installed on the upper part of the tank body 1 below the air outlet 3, which facilitates fine separation, interception and aggregation of gas containing tiny droplets entering the mist eliminator on the upper part of the tank body 1. The gas can pass through the mesh gaps on the mist eliminator, while the droplets are intercepted by the mist eliminator due to inertia. At the same time, the droplets aggregate on the mist eliminator due to surface tension, and the small droplets merge into large droplets. When the weight of the droplet exceeds the buoyancy of the gas, it drips downward and enters the settling zone at the lower part of the tank body 1, thus completing the separation of tiny droplets.

[0023] The drain port 7 is located at the lowest point of the tank body 1 to ensure that all accumulated liquid in the tank body 1 can be collected here by gravity settling, making it easy to drain. The drain port 7 is connected to a drain valve to drain the accumulated liquid. The lower part of the tank body 1 is provided with a drain port 8 located on one side of the drain port 7 for draining impurities, which facilitates the discharge of impurities, protects the tank body 1, facilitates gas-liquid separation, and periodically discharges deposited impurities to prevent blockage of the drain valve.

[0024] The liquid level gauge is linked to the drain valve to prevent liquid overflow and avoid gas leakage. When the liquid level exceeds the upper safety limit, the drain valve will open automatically to prevent liquid overflow. When the liquid level is below the lower safety limit, the drain valve will close automatically to avoid gas leakage.

[0025] The tank 1 includes a cylindrical body, and end caps are welded to both the upper and lower ends of the cylindrical body. The end caps are used to close the ends of the cylindrical body, thereby forming a closed space, optimizing the airflow distribution inside the tank 1, and reducing resistance. In addition, the curved structure of the end caps can evenly distribute the internal pressure of the tank 1 to the cylindrical body and the end caps, avoiding cracking of the tank 1 caused by local stress concentration.
