Description

Technical Field

[0001] The utility model relates to the technical field of condensation, in particular to a solvent circulation recovery device. Background Art

[0002] During the production process of fire-fighting agents, paints, coatings, aerogels, etc. containing volatile solvents, some of the solvents will be vaporized. If this vaporized solvent is directly discharged, it will not only pollute the environment but also cause waste, so it needs to be recycled.

[0003] Existing condensation tanks for recovering gaseous solvents mainly absorb heat from the gaseous solvent through the internal condenser tube. In order to increase the contact area between the condenser tube and the gaseous solvent, existing methods generally design the condenser tube to be spiral. Although this can increase the heat exchange area, there is still a large amount of available heat exchange space inside the condenser tank that may not be utilized, and most existing condensation tanks do not have pre-cooling treatment. Therefore, even if a spiral condenser tube is used, the condensation effect is still insufficient. Utility Model Content

[0004] The purpose of the present invention is to provide a solvent recycling recovery device in order to solve the above problems, as described below.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The utility model provides a solvent recycling recovery device, comprising a tank body, wherein the tank body is connected to a pre-cooling component;

[0007] The pre-cooling assembly includes a sleeve, a plurality of heat dissipation pipes are provided through the sleeve, a shell is provided on the surface of the sleeve, and a cavity for airflow is formed between the shell and the sleeve, and both ends of the heat dissipation pipes are connected to the cavity, a sealing cover is provided on the top of the shell, an input pipe and a connecting pipe for airflow to enter the cavity are provided through the sealing cover, and the connecting pipe is connected to the cavity;

[0008] One end of the sleeve away from the sealing cover is in communication with the tank body, and an annular storage cavity is provided on the inner wall of the tank body for storing coolant;

[0009] A spiral condenser is provided in the tank body, and both ends of the condenser are connected to the storage cavity;

[0010] The storage cavity is connected to a cooling assembly for cooling the coolant and allowing the coolant to circulate in the storage cavity and the spiral condenser tube.

[0011] In the solvent recycling and recovery device described above, the high-temperature gaseous solvent first enters the pre-cooling assembly through the input pipe, then enters the sleeve and contacts a plurality of heat dissipation pipes. The heat dissipation pipes can absorb the heat of the gaseous solvent, thereby achieving pre-cooling. At the same time, the heat dissipation pipes can block the gaseous solvent, reduce its flow rate, increase the contact time between the gaseous solvent and the condensing medium, and improve the liquefaction effect. The airflow delivered to the cavity from the outside can flow in the heat dissipation pipes, and the airflow can reduce the heat of the heat dissipation pipes, so that the heat dissipation pipes can continue to absorb heat from the gaseous solvent.

[0012] The pre-cooled solvent enters the tank and contacts the surface of the storage cavity and the spiral condenser tube. The storage cavity and the spiral condenser tube quickly absorb the heat of the solvent, causing it to liquefy and collect in the tank. The cooling assembly and the coolant cooperate to transfer the heat absorbed by the storage cavity and the spiral condenser tube to the environment.

[0013] The heat of the gaseous solvent can be further absorbed by the condensation ring, and the liquefied solvent droplets can flow to the bottom of the tank along the guidance of the condensation ring for easy collection.

[0014] Preferably, the connecting pipe is connected to a blower through an air supply pipe, and the blower can deliver airflow into the connecting pipe.

[0015] Preferably, an air outlet is provided on the surface of the shell, and the air outlet is connected to the cavity. There are two independent cavities, and the air outlet and the connecting pipe correspond to the two cavities respectively. The two ends of the heat dissipation pipe correspond to the two cavities respectively.

[0016] Preferably, the heat dissipation pipe is made of copper.

[0017] Preferably, the cooling assembly includes a heat dissipation water tank, a circulation pipe 1 and a circulation pipe 2, the circulation pipe 1 and the circulation pipe 2 are both connected to the storage chamber, and the other end of the circulation pipe 1 is connected to the water inlet end of the heat dissipation water tank, the other end of the circulation pipe 2 is connected to the water outlet end of the heat dissipation water tank through a circulation pump, the output end of the circulation pump is connected to the circulation pipe 2, and a fan is provided on the heat dissipation water tank.

[0018] Preferably, a plurality of vertically arranged condensation rings are provided in the tank body.

[0019] Preferably, the condensation ring is made of metal, and the upper side of the condensation ring is a downward slope.

[0020] Preferably, the bottom of the tank body is provided with support legs and a liquid collecting pipe for discharging the liquefied solvent.

[0021] The beneficial effects are:

[0022] 1. The heat of the gaseous solvent can be absorbed by the heat pipe to achieve pre-cooling. At the same time, the heat pipe can block the gaseous solvent, reduce its flow rate, increase the contact time between the gaseous solvent and the condensing medium, and improve the condensation effect. The airflow delivered to the cavity from the outside can flow in the heat pipe. The airflow can reduce the heat of the heat pipe, so that the heat pipe can continue to absorb heat from the gaseous solvent. The contact area between the tank body and the gaseous solvent is increased by providing a storage cavity and a spiral condenser pipe, which can quickly absorb the heat of the solvent and liquefy it. The heat absorbed by the storage cavity and the spiral condenser pipe can be transferred to the environment through the cooperation of the cooling component and the coolant, thereby significantly improving the condensation effect of the device.

[0023] 2. The heat of the gaseous solvent can be further absorbed by the condensation ring, and the liquefied solvent droplets can flow to the bottom of the tank along the guidance of the condensation ring for easy collection. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The heat dissipation water tank 6 is a prior art, and the circulating pump 10 enables the coolant to flow between the storage chamber 4, the spiral condenser 20 and the heat dissipation water tank 6.

The storage chamber 4 and the spiral condenser tube 20 can quickly absorb the heat of the solvent, causing it to liquefy and collect in the tank body 1. The cooling component 5 cooperates with the coolant to transfer the heat absorbed by the storage chamber 4 and the spiral condenser tube 20 to the environment.
