Description

Technical Field

[0001] This utility model belongs to the field of organic solvent technology, specifically relating to a multi-stage condensation organic solvent regeneration device. Background Technology

[0002] Organic solvents are carbon-containing volatile liquids that can dissolve other organic substances (such as resins and oils). They are commonly used in industrial production and laboratories. Examples include: hydrocarbons such as toluene and gasoline; oxygenated solvents such as ethanol (alcohol) and acetone; and halogenated hydrocarbons such as chloroform and carbon tetrachloride. Most organic solvents are flammable and explosive (such as ether and acetone), and some are toxic or carcinogenic (such as benzene and chloroform). They are highly volatile and easily diffuse to form VOCs (volatile organic compounds).

[0003] Existing organic solvent regeneration equipment separates and purifies volatile organic compounds (VOCs) from the gaseous or mixed state through physical or chemical means, realizing the recycling of solvents and pollution reduction. However, in actual use, it is inconvenient to perform multi-stage condensation on organic solutions, which can easily lead to incomplete regeneration of organic solutions, impurities, and incomplete recovery, affecting quality. Therefore, we need to upgrade and modify the existing technology. Utility Model Content

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1 As shown in Figure 5, this embodiment provides a multi-stage condensation organic solvent regeneration device, including a device body 1. The device body 1 contains a blower 2. The front end of the blower 2 is connected to an air suction pipe 3, and the rear end of the blower 2 is connected to an air inlet pipe 4. One end of the air inlet pipe 4 is connected to a primary condenser 6. A secondary condenser 7 and a tertiary condenser 8 are arranged on the side of the primary condenser 6. A gas-liquid separator 10 is connected to the side of the tertiary condenser 8. A solvent tank 13 is connected below the gas-liquid separator 10, and one end of the gas-liquid separator 10 is connected to a connecting pipe 14. A second liquid inlet pipe 19 is connected below the solvent tank 13. The connecting pipe 14 is connected to an activated carbon adsorption tower 15. A connector 17 is provided on the activated carbon adsorption tower 15. A first liquid inlet pipe 18 is connected to the connector 17. One end of the first liquid inlet pipe 18 and the second liquid inlet pipe 19 is connected to a sealed storage tank 20. A filter screen 21 is provided inside the air suction pipe 3, and a limit buckle 24 is connected to the filter screen 21.

[0026] Preferably, connecting pipes 9 are fixedly connected between the primary condenser 6, the secondary condenser 7, and the tertiary condenser 8. By setting the connecting pipes 9, the primary condenser 6, the secondary condenser 7, and the tertiary condenser 8 can be connected and fixed, which facilitates the user's control and use of the device. A support frame 12 is installed below the gas-liquid separator 10. The support frame 12 is fixedly connected to the gas-liquid separator 10. By setting the support frame 12, the gas-liquid separator 10 can be supported, which increases the stability of the gas-liquid separator 10 and ensures the safety of the gas-liquid separator 10 during use. An observation window is opened in the solvent tank 13 and scale lines are set on both sides of the observation window. The observation window is made of transparent material. By setting the observation window, the solvent in the solvent tank 13 can be observed. By setting the scale lines, the amount of solvent in the solvent tank 13 can be recorded, which provides convenience for the user.

[0027] Preferably, a pressure gauge 11 is fixedly installed between the three-stage condenser 8 and the gas-liquid separator 10. By installing the pressure gauge 11, the pressure generated between the three-stage condenser 8 and the gas-liquid separator 10 can be detected, increasing the practicality of the device and providing convenience for the user. The suction pipe 3 has a positioning groove 23, and multiple sets of positioning grooves 23 are provided. Limit buckles 24 are movably installed in the multiple sets of positioning grooves 23. By setting the positioning grooves 23, the limit buckles 24 can be installed, thereby facilitating the user to position and install the filter screen 21, increasing the closeness and connection between the devices. Both the positioning grooves 23 and the limit buckles 24 have screw holes 25, and bolts 26 are screwed into the screw holes 25. By setting the screw holes 25 and the bolts 26, the filter screen 21 can be limited and fixed, ensuring the safety and stability of the filter screen 21 during use, and facilitating the user to disassemble and replace it later.

[0028] The working principle and process of this utility model are as follows: During use, blower 2 is turned on, driving the suction pipe 3 to adsorb the waste gas containing organic solvents. The inhaled waste gas containing organic solvents is filtered through filter screen 21 and then enters the inlet pipe 4. The waste gas containing organic solvents then enters the primary condenser 6, secondary condenser 7, and tertiary condenser 8 for condensation treatment. After treatment, the waste gas containing organic solvents condenses from gaseous solvent to liquid. The liquid solvent is then collected by the gas-liquid separator 10. The incompletely condensed gas enters the activated carbon adsorption tower 15 through the connecting pipe 14 for further purification. The solvent entering the solvent tank 13 enters the sealed storage tank 20 through the second liquid inlet pipe 19 for sealed storage. Simultaneously, the solvent purified by the activated carbon adsorption tower 15 enters the sealed storage tank 20 through the first liquid inlet pipe 18 for sealed storage. This system enables the regeneration of solvents containing waste gas through multi-stage condensation and regeneration, facilitating solvent recycling and reducing VOC emissions. This lowers production costs and improves recovery efficiency. When the filter screen 21 needs to be disassembled and replaced, the user can use tools to rotate the bolts 26 out of the screw holes 25. After removal, the user can remove the limiting buckle 24 of the filter screen 21 from the positioning groove 23. After removal, the user can clean or replace the filter screen 21. After cleaning, the filter screen 21 can be re-secured. This system allows for the installation and fixation of the filter screen 21, facilitating future disassembly and cleaning by the user. It avoids clogging caused by long-term accumulation of particulate matter, maintains smooth airflow and system stability, and extends the working time and service life of the device.
