Equipment Characteristics And Advantages
1. The device uses activated carbon fibers with a large specific surface area (1000~1500㎡/g) and uniform microporous structure as the adsorption material, which has the advantages of high purification efficiency and less filling amount of adsorption materials.
2. The adsorption and desorption time of organic solvents are short, the speed is fast, and the quality of recovered solvents is good.
3. The entire system is controlled by microcomputer programs and can be operated manually or automatically, with easy operation and high reliability.
4. The equipment and components in the system are assembled in a compact structure, which is easy to install and occupies a small area.
5. Vibration reduction, sound insulation, explosion prevention, over-temperature, and over-pressure protection measures are adopted for all equipment and components in the system, ensuring safe operation and suitability for installation in various locations such as workshop floors, floors and roofs.
6. The air flow rate is designed according to the user's requirements.
Process Flow And Working Principle
The working principle of this device is based on the adsorption force of microporous active materials on solvent molecules or clusters. When industrial waste gas passes through the adsorption medium, the organic solvents in it are "trapped" and removed, resulting in the purification of organic waste gas. According to the theory of molecular thermal motion, when thermal energy is added to the adsorption system from the outside, it increases the thermal motion energy of adsorbed molecules or clusters. When the thermal motion force is sufficient to overcome the adsorption force, the organic solvent molecules will "break free" from the adsorption system, and the adsorption medium will be regenerated. This device has two sets of adsorbers filled with activated carbon fiber felts, A and B, for cyclic adsorption -saturation- desorption -regeneration processes.
The state of organic solvents depends on the temperature and pressure of the environment. The organic solvents dissociated from the adsorber are in a gaseous state when the pressure they experience at high temperature is below or close to the saturation vapor pressure corresponding to the temperature. After the temperature of the organic solvents is lowered through a condenser (heat exchanger), the corresponding saturation vapor pressure also decreases, and the pressure in the system will be much higher than the organic vapor pressure, the organic solvents condense into a liquid. The solvent and condensate mixed liquid flows into the separator. Most organic solvents are insoluble or slightly soluble in water. The organic solvents are recovered from the separator by utilizing the principle of gravity separation based on the difference in specific gravity between solvents and water. The condensate is discharged after explosion-proof treatment.
