The height of the liquid outlet 1b is lower than that of the gas inlet 1a, so that the liquid collected at the bottom of the vertical vessel 1 does not block the gas inlet 1 a. The top of the container tank 1 is opened with a gas outlet 1c, and the purified gas is discharged from the gas outlet 1 c.

The fiber bed structure is positioned between the gas inlet 1a and the gas outlet 1c and comprises a fiber bed and a tube plate 2, the fiber bed is arranged between the tube plate 2 and the gas inlet 1a, the thickness of the fiber bed is 20-200 mm, and the density of the bed layer of the fiber bed is 100-500 kg/m³In this example, there are 2 fiber beds.

The fiber bed comprises a cylindrical inner framework, 9 fiber layers wound on the inner framework, a cylindrical outer framework 3a and a bottom plate 3b, wherein the cylindrical outer framework 3a and the bottom plate 3b are sleeved outside the 9 fiber layers, one end of the inner framework is welded with the tube plate 2, and the bottom plate 3b is fixedly connected with the inner framework and one end, far away from the tube plate 2, of the outer framework 3a respectively.

The gas to be purified sequentially passes through the outer framework 3a, the fiber layer, the inner framework and the tube plate 2 to obtain purified gas, and the purified gas is discharged out of the vertical container tank 1 from the gas outlet 1 c.

Along the direction from the inner framework to the outer framework 3a, the fiber layers are respectively defined as the 1 st layer, the 2 nd layer until the 9 th layer, each fiber layer in the fiber bed is formed by spirally winding fibers on the inner framework, for example, the 2 nd layer is wound on the 1 st layer, the 3 rd layer is wound on the 2 nd layer, the outer surface of the fiber of each fiber layer of the fiber bed is coated with the modified fluorine material, the fiber of the middle fiber layer (the 5 th layer in this embodiment) of the 9 fiber layers is made of the lyophobic material, the lyophobic material is PVDS, PTFE or polypropylene, etc., the diameter of the fiber layer (the 1 st layer in this embodiment) tightly attached to the inner skeleton is 100-300 um, except the fiber of the 1 st fiber layer in this embodiment, the diameters of the fibers of other fiber layers are all between 5 and 100um, and the specific diameters of all the fiber layers are selected according to actual conditions.

the fiber is made of metal, glass fiber or polyester material, and the specific material of the fiber is determined according to the actual application scene; the thickness of the fiber bed can be 20-200 mm, and the density of the bed layer of the fiber bed can be 100-500 kg/m³Taking values; the number of fiber layers of the fiber bed can be other numbers, which is determined according to practical situations and is not limited herein.

The working process of the embodiment is as follows:

The gas to be purified enters the vertical container tank 1 from the gas inlet 1a, flows upwards, then sequentially passes through the outer framework 3a, the 9 fiber layers, the inner framework and the tube plate 2, and then is discharged from the gas outlet 1c, wherein the 9 fiber layers are used for separating fog drops in the gas to be purified. When the gas to be purified containing the fog drops passes through the fiber bed, the fog drops are captured on the fiber bed through three mechanisms of inertial collision, direct interception and Brownian motion, are gradually condensed into large particles or liquid films, pass through the fiber bed under the push of airflow, and are discharged out of the bed layer of the fiber bed along the inner surface of the inner framework under the action of gravity. The layer close to the inner skeleton is a fiber layer with a larger diameter so as to promote liquid drainage and prevent the fog drops from being carried secondarily by airflow. The separated liquid is collected at the bottom of the vertical vessel 1, and finally discharged from the vertical vessel 1 through the liquid outlet 1 b.
