[0020] The liquid collecting mechanism 2 includes a first liquid collecting plate 201, a second liquid collecting plate 202, a liquid collecting frame 203 and a water supply pipe 204. The first liquid collecting plate 201 and the second liquid collecting plate 202 are both located in the cylinder 1 and fixedly connected, and the contact end and the exhaust end of the second liquid collecting plate 202 respectively correspond to the exhaust end of the guide mechanism 4 and the second liquid collecting plate 202. There are two liquid collecting frames 203, and the two liquid collecting frames 203 respectively correspond to the discharge ends of the first liquid collecting plate 201 and the second liquid collecting plate 202. The liquid inlets of the first liquid collecting plate 201 and the second liquid collecting plate 202 are respectively connected to the water supply pipe 204, and a confluence pipe is connected between the drainage outlets of the two liquid collecting frames 203 to facilitate the collection of condensed chlorobenzene by the staff.

[0021] The first liquid collecting plate 201 and the second liquid collecting plate 202 are both conical hollow plates, and the first liquid collecting plate 201 and the second liquid collecting plate 202 are arranged vertically, and the liquid collecting frame 203 is located on one side of the bottom end of the inclined surface of the first liquid collecting plate 201 and the second liquid collecting plate 202.

[0022] The second liquid collecting plate 202 is provided with equidistantly arranged exhaust holes, and the exhaust holes are not connected to the hollow cavity in the second liquid collecting plate 202 .

[0023] The liquid inlet of the hollow cavity in the second liquid collecting plate 202 is connected to the liquid discharge port of the hollow cavity in the first liquid collecting plate 201 through the water supply pipe 204, and the liquid inlet of the hollow cavity in the first liquid collecting plate 201 is also connected to the liquid inlet of the cylinder 1 through the water supply pipe 204.
