Technical Field

[0001] The utility model relates to the field of gas scrubbing and gas-liquid separation, in particular to a gas-liquid separation device with a gas scrubbing function. Background Art

[0002] During the MVR evaporation process, especially during the falling film evaporation process, a falling film separator and a scrubbing tower are usually used. The falling film separator is mainly used for gas-liquid separation after liquid phase flash evaporation, while the scrubbing tower is used for cleaning and purifying the secondary steam.

[0003] However, in the existing process, the falling film separator and the scrubbing tower are two independent devices with different functions. They are connected by pipelines, and due to the large diameter of the pipelines, a large turning radius is required, resulting in a large floor area of the equipment and high installation and maintenance costs. Summary of the Utility Model

[0005] To achieve the above object, the utility model adopts the following technical scheme: A gas-liquid separation device with a gas scrubbing function includes a cylinder body, which is used to receive and place the gas-liquid mixture to be processed. An empty slot is opened inside the cylinder body, and a sedimentation mechanism is connected to one end inside the empty slot. The sedimentation mechanism is used to precipitate and separate the sundries in the gas-liquid mixture. A separation mechanism is connected to one side of the sedimentation mechanism, and the separation mechanism is used to separate gas and liquid. A cleaning mechanism is connected to the upper end of the separation mechanism, and the cleaning mechanism is filled with a cleaning liquid for cleaning the discharged gas.

[0006] Preferably, a water inlet pipe is connected to one end of the cylinder body, and brackets are connected to both sides of the lower end of the cylinder body. The sedimentation mechanism includes a sedimentation tank. A circular notch is opened on one side of the sedimentation tank close to the water inlet pipe, and a first water pipe is connected to the end of the sedimentation tank far from the water inlet pipe.

[0007] Preferably, a screening plate is connected inside the sedimentation tank, and an empty slot is opened inside the screening plate. Equally spaced holes are opened on the outer side of the screening plate. One end of the upper end of the screening plate is connected to a first liquid inlet pipe.

[0008] Preferably, a first conical barrel is connected to the middle of the lower end of the sedimentation tank, a first regulating valve is connected to the middle of the lower end of the first conical barrel, and a first collection box is connected to the outer side of the lower end of the first conical barrel.

[0009] Preferably, the separation mechanism includes a second water pipe, and one end of the second water pipe is connected to a separation chamber. Two baffle plates are arranged inside the separation chamber, and a water chamber is connected to the lower end of the separation chamber.

[0010] Preferably, the middle part of the lower end of the water chamber is connected with a second conical barrel, and a second regulating valve is connected inside the lower end of the second conical barrel. A second collection box is connected to the outside of the lower end of the second conical barrel. The upper end of the separation chamber is connected with an air chamber, and the middle part of the upper end of the air chamber is connected with a cleaning mechanism.

[0011] Preferably, the cleaning mechanism includes an air pipe. A plurality of exhaust holes are opened at the upper end of the air pipe. A cleaning chamber is arranged on the outer side of the air pipe. A rectangular notch is opened on one side of the cleaning chamber. An observation window is connected inside the notch.

A drain pipe is connected to the upper end of the side opposite to the air pipe inside the cleaning chamber. One end of the drain pipe is connected with a water separation net.

[0012] The beneficial effects of the present utility model are as follows: The device receives the gas-liquid mixture to be separated through the water inlet pipe on one side of the cylinder body, sets the sedimentation mechanism and the separation mechanism inside the cylinder body for gas-liquid separation, and sets the cleaning mechanism above the cylinder body to clean the gas, reducing the connecting pipes and turning radius between devices, thereby reducing the floor area of the device. And due to the simplification of the device structure, the complexity of installation and maintenance is reduced, and the installation and maintenance costs are reduced. The flocculant is attached to the screening plate through the first liquid inlet pipe, and the impurities in the gas-liquid mixture are aggregated together to form larger particles for precipitation. Cooperating with the baffle plate inside the separation chamber in the separation mechanism, the liquid flows through the water chamber and the second conical barrel to the second collection box, and the gas is transmitted to the cleaning mechanism through the air chamber, realizing rapid gas-liquid separation.
