This is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as limiting the present invention. In addition, if the terms "first", "second", etc. appear in the description of the present invention, they are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0018] In the description of the embodiments of the present invention, it should be noted that, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0019] As shown in the accompanying drawings, the present invention comprises a cylinder 1, which is divided into an upper cylinder portion 11 and a lower cylinder portion 12 by a grid partition 4, wherein the upper cylinder portion 11 is filled with a filler 5;

[0020] An air inlet pipe 2 is arranged obliquely downward and penetrates the lower cylinder portion 12 and extends into the lower cylinder portion 12. The air inlet pipe 2 guides the gas-liquid mixture into the gas-liquid deceleration buffer space of the lower cylinder portion 12;

[0021] The upper end of the liquid sealing tube 3 is connected to the bottom of the lower cylinder portion 12, and the lower end of the liquid sealing tube 3 is connected to the filtrate storage tank.

[0022] In another technical solution, the inlet end of the air inlet pipe 2 is connected to the back-flushing gas inlet pipe 6 of the air-drying back-flushing system of the plate and frame filter press.

[0023] In another technical solution, the partition 5 is a stainless steel grid or a fiberglass grid.

[0024] In another technical solution, the filler 5 is a poly-saddle ring, which reduces the gas flow rate and recovers the remaining liquid by attachment, thereby reducing the liquid content of the exhausted gas.

[0025] In another technical solution, the top of the upper cylindrical portion 11 is connected to a gas exhaust pipe 13, and the gas is discharged after being buffered by the filler to eliminate the remaining liquid.

[0026] In another technical solution, the included angle between the air inlet pipe 2 and the cylinder 1 is 30-45 degrees, and the air inlet pipe enters tangentially to allow the airflow to rotate, and the liquid is recovered to the filtrate storage tank by natural gravity under the influence of gravity.

[0027] In another technical solution, the grid partition 4 is located in the middle of the cylinder 1.

[0028] Working mode: The back-flushing gas of the air-drying back-flushing system of the plate and frame filter press first enters the gas-liquid deceleration buffer space of the lower cylinder 12 through the air inlet pipe 2. The gas-liquid mixture reduces the flow rate by expanding the volume, effectively separating the gas and liquid. The liquid returns to the liquid seal pipe 3 and the filtrate storage tank through gravity drop. The gas is discharged after the filler buffers the flow rate and eliminates the remaining liquid.

[0029] The utility model recovers the residual filtrate of the air-dried back-blowing of the filter press. Since the air-dried back-blowing gas has a high air velocity and a high noise, a gas-liquid separation device with a silencer function is added above the filtrate storage tank. By enlarging the pipe diameter and reducing the air velocity, the air inlet pipe enters tangentially to allow the air flow to rotate. The liquid is recovered to the filtrate storage tank by natural gravity under the influence of gravity. The gas is buffered by the filler above, which reduces the air velocity and reduces the noise, and is naturally discharged from the top.

[0030] The above implementation cases are only for illustrating the technical solutions and features of the utility model, and their purpose is to enable people familiar with the technology to implement them better. They cannot be used to limit the scope of protection of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model are within the scope of protection of the utility model. Those not described in detail are prior art.
