[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0013] Referring to Figure (1-2), a solvent recovery device includes a device body 1, characterized in that: two layers of cavity are arranged in the device body 1, namely an outer cold water layer 31 and an inner cold water layer 32, and a collecting chamber 11 is arranged between the outer cold water layer 31 and the inner cold water layer 32, and the bottom of the collecting chamber 11 is connected with the storage chamber 12, and two spiral condensation pipes 2 are arranged in the outer cold water layer 31, one end of the condensation pipe 2 is connected with the bottom of the collecting chamber 1, and the other end passes through the device body 1 and is connected with an external pump body, the outer cold water layer 31 and the inner cold water layer 32 are connected by a connecting pipe 13, the bottom of the outer cold water layer 31 is provided with a liquid inlet 14, the top of the inner cold water layer 32 is provided with a liquid outlet 15, and the top of the collecting chamber 11 is provided with an exhaust port 16.

[0014] The collecting chamber 11 is provided with a multi-layer guide plate 4, and the guide plate 4 is composed of a plurality of inclined plates. One end of the connecting pipe 13 connected to the inner cold water layer 32 extends into the bottom of the inner cold water layer 32. The bottom of the storage chamber 12 is provided with an opening, and a valve is provided at the opening.

[0015] When the device is in use, the vaporized medium is pumped into the condensation pipe 2 through the air pump, and the gas exchanges heat with the cold water in the outer cold water layer 31 in the condensation pipe 2. The solution produced by the condensation and the remaining gas enter the collection chamber 11, and the solution flows into the storage chamber 12 under the action of its own gravity. During the rising process of the gas, it contacts the side walls of the outer cold water layer 31 and the inner cold water layer and exchanges heat, and performs secondary condensation. When the gas passes through the guide plate 4, it moves obliquely along the inclined plate, which increases the residence time of the gas in the collection chamber, and finally flows out from the exhaust port on the top of the collection chamber; during condensation, cold water is pumped into the outer cold water layer from the liquid inlet 14 through the water pump, and after entering the inner cold water layer from the outer cold water layer through the connecting pipe, it flows out from the liquid outlet 15, realizing the replacement of cold water in the outer cold water layer and the inner cold water layer.
