Description
Technical field
The invention belongs to solvent recovery technical field, specifically discloses a kind of volatile solvent condensate recycling device.
Background technology
In water-absorbing material carries out surface hydrophobicity modifying process, typically led to using equipment in host material inner and outer surfaces
Cross chemical reaction and be grafted or coated one or more layers hydrophobic group or organic matter, these hydrophobic groups or organic matter are reacting
Purpose before to host surface for dissolving, dilution needs to add one or more volatile solvents, to improve reaction effect
Rate and quality.In above process, volatile solvent is the consumptive material in course of reaction, is completed after above-mentioned reaction terminates, need by
Volatile solvent recycling.Otherwise, volatilize have solvent can will be serious environmental pollution and produce potential safety hazard, together
When also result in substantial amounts of waste.
When being recycled to such volatile solvent, volatilization is heated using the volatility of solvent, then will wave
To send out into gaseous solvent and carry out condensation process, condensed solution is purified or separating treatment, separates its each component, so as to
It is easy to reuse.Condensation process is mainly carried out using condenser at present, and condenser internal temperature is relatively low, can be by most of gas
The solvent of state is condensed into solution.Because solution has the characteristic of volatilization, if being separated again after by its most of component condensation
Or purification process, contained constituent part will continue to volatilize in the process in solution, cause the pollution of working environment.Simultaneously
The processes such as condensation, separation are separately handled, complex procedures, less efficient, so that the recycling of solvent is less efficient.
The content of the invention
The purpose of the present invention is providing a kind of volatile solvent condensate recycling device, to solve volatile solvent recycling
The problem of efficiency is low.
