What are the common ways the solvent recovery machine works?
Now everyone should know one thing, that is, no matter what the working principle of the machine is there are many kinds of, so do you know what are the common recycling ways? The following is introduced by the solvent recovery machine.
1, freezing condensation method
Some mixed gases have a single solvent gas and a high concentration (for example, when the gasoline can oil at the gas station in summer, only gasoline vapor is discharged from the outlet), and its saturated vapor pressure varies greatly with temperature. In this case, the method of freezing condensation can be used, that is, the mixed gas is cooled and condensed through the snake tube or shell tube condenser, the solvent will be separated from the mixed gas into a liquid, the cooling can be used freon and other refrigerants, and the liquid nitrogen evaporation solvent recovery mechanism can be cold, according to the needs and conditions of recovery, using different refrigerants. The solvent recovered by this method has a high purity and can be used without any other treatment. However, this method is not applicable in the following cases: 1) the amount of discharged gas is large and the solvent content is low; 2) The saturated vapor pressure does not change much with temperature; 3) The mixed gas contains a variety of solvent gases, and their saturated vapor pressure varies with temperature.
2, solid adsorption method
Used as solid adsorbents are molecular sieve, solvent recovery machine activated carbon and activated carbon fiber. Molecular sieve because of its small pores, expensive, used for gas drying and less large-scale solvent recovery production, more used for gas purification. Activated carbon is a large number of adsorbent used in solvent recovery, from the early 20th century is still thriving. Activated carbon has a good effect of trapping solvent gas from solvent air mixture, and it is easy to be used for water vapor desorption and regeneration. For solvent gases that are not easy to oxidize, such as alkane solvents, they can be desorbed by hot air; For easily oxidized solvent gases, they can be desorbed by thermal inert gases such as pure nitrogen.
KUANBAO Environmental Protection Equipment Co., LTD., 30 years of professional production of solvent recovery machine, with the following advantages:
