[0020] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0021] The utility model provides a baffle plate type gas-liquid separator, aiming to solve the problems of complex structure and difficult cleaning of the existing baffle plate type gas-liquid separator.

[0022] like Figure 1 As shown, a baffle plate type gas-liquid separator includes a separation tank 1 and a baffle assembly 2. A chamber 1.1.1 is formed in the separation tank 1, and an air inlet 1.2.1 and an air outlet 1.3.1 connected to the chamber 1.1.1 are provided on the separation tank 1. The air inlet 1.2.1 and the air outlet 1.3.1 are respectively arranged on both sides of the separation tank 1; the baffle assembly 2 includes a partition 2.1 and a plurality of horizontally arranged diverter plates 2 .2, the partition 2.1 is arranged in the cavity 1.1.1, and the partition 2.1 divides the cavity 1.1.1 into a first chamber 1.1.1.1 and a second chamber 1.1.1.2 which are connected at the top, the first chamber 1.1.1.1 is connected to the air inlet 1.2.1, and the second chamber 1.1.1.2 is connected to the air outlet 1.3.1; a plurality of diverter plates 2.2 are arranged in the first chamber 1.1.1.1 at intervals along the vertical direction. After the gas enters the separation tank 1 through the air inlet 1.2.1, it flows upward in the first chamber 1.1.1.1, and the gas contacts each separation plate in turn, and then flows into the second chamber 1.1.1.2 from the upper space, and flows out through the air outlet 1.3.1, and the gas-liquid separation is completed in this process. The utility model has a simple structure and is easy to clean, and can improve the gas-liquid separation effect by increasing the impact area between the gas and the wall and prolonging the residence time of the gas in the tank. According to different types of separation tanks 1, flow dividers 2.2 of different shapes are provided to ensure the gas-liquid separation effect.

[0023] Based on the above embodiment, the widths of the plurality of diverter plates 2.2 increase successively in the direction away from the air inlet 1.2.1, and the ratio of the width difference between two adjacent diverter plates to their spacing value is less than 0.25. In actual operation, the number and width of the diverter plates 2.2 can be adjusted according to demand, the number of diverter plates 2.2 increases, and the width of the diverter plates 2.2 increases in the direction away from the air inlet 1.2.1, so that the gas flow path is lengthened, the gas residence time increases accordingly, the degree of airflow disturbance is aggravated, and the separation effect is also improved, but the corresponding pressure loss and equipment cost are brought about. The plate width of the diverter plate 2.2 determines the gas flow area at that location, which affects the degree of gas vortex. In this embodiment, three diverter plates are provided, and the ratios of the flow area of ​​the diverter plate to the area of ​​the left chamber of the tank (measured from bottom to top) are: 0.6, 0.4, and 0.25, respectively. In specific applications, the ratios can be adjusted according to actual conditions.

[0024] Specifically, the partition 2.1 includes a vertical portion 2.1.1 and a horizontal portion 2.1.2 connected to each other, the two sides of the vertical portion 2.1.1 are respectively connected to the inner wall of the cavity 1.1.1, and the horizontal portion 2.1.2 is connected between the vertical portion 2.1.1 and the inner wall of the cavity 1.1.1 to seal the bottom of the second chamber 1.1.1.2. The partition 2.1 forms an air flow channel from the air inlet 1.2.1 to the first chamber 1.1.1.1, then to the second chamber 1.1.1.2, and finally out of the air outlet 1.3.1 inside the separation tank 1, so as to further extend the gas flow path and improve the gas-liquid separation effect.

[0025] Furthermore, the baffle plate type gas-liquid separator also includes an anti-impact component 3, which includes a connector 3.1 and an anti-impact plate 3.2. The anti-impact plate 3.2 is connected to the vertical portion 2.1.1 through the connector 3.1, and the anti-impact plate 3.2 is arranged opposite to the air inlet 1.2.1. The airflow flows from the air inlet 1.2.1 into the first chamber 1.1.1.1, changes the direction of the gas after contacting the anti-impact plate 3.2, flows upward through a plurality of diverter plates 2.2 and then enters the second chamber 1.1.1.2 to complete the gas-liquid separation.

[0026] Furthermore, the distance between the anti-collision plate 3.2 and the air inlet 1.2.1 is 1 to 1.5 times the size of the air inlet 1.2.1. The size of the air inlet can be felt by the amount of air entering the tank body. The distance between the anti-collision plate 3.2 and the air inlet 1.2.1 should be equal to or slightly larger than the size of the air inlet to ensure that the airflow out of the air inlet can be evenly diffused when it contacts the anti-collision plate. The distance between the anti-collision plate 3.2 and the partition 2.2 is 50 mm, and this distance is set to meet the necessary space during production. Preferably, a gas uniform diffuser is provided at the air inlet.

The air inlet pipe 1.2 extends into the tank body 1.1 to shorten the distance between the air inlet 1.2.1 and the anti-collision plate 3.2, thereby ensuring the effect of the anti-collision plate 3.2 in changing the direction of the gas. The air inlet pipe 1.2 and the air outlet pipe 1.4 are provided to facilitate the connection between the separation tank 1 and the external device.

[0028] The tank body 1.1 is provided with an exhaust port 1.1.2 and a drain port 1.1.3. The exhaust port 1.1.2 is arranged at the top of the tank body 1.1 and is connected to the connection point between the first chamber 1.1.1.1 and the second chamber 1.1.1.2, and is used to discharge the gas in the chamber 1.1.1; the drain port 1.1.3 is arranged at the bottom of the tank body 1.1 and is connected to the first chamber 1.1.1.1, and is used to discharge the liquid in the first chamber 1.1.1.1; the baffle plate type gas-liquid separator also includes an exhaust screw plug 4, and the exhaust screw plug 4 is used to block the exhaust port 1.1.2. In the process of the gas passing through the multiple diverter plates 2.2 in the first chamber 1.1.1.1, the liquid droplets in the gas are separated and gathered at the bottom of the first chamber 1.1.1, and can be discharged through the drain port 1.1.3 to avoid blockage. When the condensate at the bottom of the tank 1.1 needs to be discharged, in order to avoid the pressure difference between the inside and outside of the tank affecting the condensate discharge, an exhaust screw plug 4 is provided to balance the internal and external pressures when discharging the condensate. This gas-liquid separation tank is suitable for use under conditions with low flow rates. This gas-liquid separation tank can be improved as follows as needed.

[0030] ② When the gas working conditions are large air volume, high liquid content, small droplets, etc. and the gas is clean, a thin wire mesh can be added between the splitter plate 2.2 and the inner wall of the container to improve the separation efficiency.

[0031] ③For some gases, when the gas and its impurities (liquid or tiny particles) are easier to separate at a certain temperature, the heat exchange components can be integrated into the container.

[0032] In addition, the baffle-type gas-liquid separator further comprises at least three legs 5 evenly arranged at the bottom of the separation tank 1 , and the legs 5 are arranged at the bottom of the separation tank 1 . The legs 5 are used to support the separation tank 1 .
