Description

Technical Field

[0001] This utility model relates to the technical field of alcohol recovery equipment, specifically to an alcohol recovery device. Background Technology

[0002] Ethanol is a volatile, colorless, and transparent liquid at room temperature and pressure. It has low toxicity, but the pure liquid is not suitable for direct consumption. An aqueous solution of ethanol has an alcoholic odor with a slightly pungent taste. Ethanol is flammable, and its vapor can form explosive mixtures with air; therefore, it usually requires recovery by workers after use.

[0003] Currently used alcohol recovery devices often exhibit uneven heating effects, resulting in inconsistent evaporation rates across different areas of the heating tank. This leads to prolonged heating time and increased energy consumption. Furthermore, the inner wall of the recovery tank is prone to corrosion due to prolonged contact with alcohol, which reduces the purity of the alcohol and affects its subsequent use.

[0004] In summary, this utility model solves the problems in the background art by designing an alcohol recovery device. Utility Model Content

[0026] For examples, please refer to Figure 1-3 This utility model provides a technical solution:

[0027] An alcohol recovery device includes a heating tank 1 and a recovery tank 2 located on the left side of the heating tank 1. An inlet valve 3 and a controller 4 are fixedly installed on the rear side of the heating tank 1. A condenser 5 is installed on the top of the heating tank 1, and a return pipe 501 is installed on the outside of the condenser 5. A heating mechanism 6 is installed inside the heating tank 1. An outlet valve 201 and a nitrogen inlet 202 are fixedly installed on the left end of the recovery tank 2. A pressure relief valve 2021 is fixedly installed on the left end of the nitrogen inlet 202. A pressure sensor 203 is installed on the rear side of the recovery tank 2. An inner lining layer 204 is installed inside the recovery tank 2. A PTFE composite layer 2041, an aluminum foil layer 2042, and a polyvinyl alcohol composite layer 2043 are respectively installed inside the inner lining layer 204.

[0028] It should be noted that one end of the liquid inlet valve 3 extends into the interior of the heating tank 1, and one end of both the nitrogen inlet 202 and the liquid outlet valve 201 extends into the interior of the recovery tank 2. The end of the return pipe 501 away from the condenser 5 is sealed and passes through the top surface of the recovery tank 2 and extends inward.

[0029] Specifically, the detection end of the pressure sensor 203 is sealed and extends into the interior of the recovery tank 2, the outer surface of the polyvinyl alcohol composite layer 2043 is in close contact with the inner wall of the recovery tank 2, and the PTFE composite layer 2041, the aluminum foil layer 2042 and the polyvinyl alcohol composite layer 2043 are integrally pressed and formed.

[0030] In this embodiment, the pressure sensor 203 is mainly used to monitor the pressure in the recovery tank 2. The nitrogen inlet 202 and the pressure relief valve 2021 are mainly used to purge nitrogen into the recovery tank 2 to prevent oxidation of the alcohol. The PTFE composite layer 2041 is mainly used to make corrosion-resistant contact with the alcohol to prevent metal ions from dissolving and contaminating the alcohol. The aluminum foil layer 2042 can block the penetration of oxygen. The polyvinyl alcohol composite layer 2043 can block the intrusion of external moisture, thereby ensuring the purity of the alcohol in the recovery tank 2.

[0031] In this embodiment, please refer to Figure 1 and Figure 2 The heating mechanism 6 includes a heating chamber 601 and a temperature sensor 602. The heating chamber 601 is located inside the heating tank 1. The heating chamber 601 is provided with a heat insulation layer 603, an electric heating tube 604 and a heat conducting layer 605. The temperature sensor 602 is fixedly installed on the inner surface of the heating tank 1.

[0032] Specifically, the heating chamber 601 is wrapped around the outer surface of the inner wall of the heating tank 1. The heat insulation layer 603 and the heat conduction layer 605 are both annular in cross-sectional shape. The electric heating tube 604 is wound in annular shape inside the heating chamber 601. The electric heating tube 604 and the temperature sensor 602 are electrically connected to the controller 4 through wires.

[0033] In this embodiment, the temperature sensor 602 is mainly used to monitor the temperature in the heating tank 1 in real time, the electric heater 604 is mainly used to generate heat, the heat insulation layer 603 can reduce the outward diffusion of heat, and the heat conduction layer 605 is mainly used to guide the heat, so that the heat is evenly transferred to the inner wall of the heating tank 1, thereby improving the heating effect of the device.

[0034] The working process of this utility model is as follows: When using an alcohol recovery device, waste alcohol solution is injected into heating tank 1 through inlet valve 3. After injection, the electric heating tube 604 is started by controller 4, and the electric heating tube begins to generate heat. With the cooperation of heat insulation layer 603 and heat conduction layer 605, the heat is evenly transferred to the inner wall of heating tank 1. When the temperature reaches the evaporation threshold, alcohol vapor rises and liquefies through top condenser 5. The liquefied alcohol then reaches recovery tank 2 through return pipe 501. At this time, pressure sensor 203 monitors the pressure inside recovery tank 2 in real time. When the pressure is insufficient, nitrogen is injected into recovery tank 2 through nitrogen inlet 202. At the same time, the polyvinyl alcohol composite layer 2043 can prevent external moisture from entering, the aluminum foil layer 2042 can block oxygen penetration, reduce the oxygen content in recovery tank 2, and prevent alcohol oxidation. The PTFE composite layer 2041 can avoid corrosion reaction with alcohol, thereby ensuring the quality of alcohol recovery and meeting the needs of users.
