Abstract
The present invention relates to chemical technology field, and in particular to a kind of solvent recovery unit；The heating kettle is connected with pressure release kettle by relief tube, and the bottom of pressure release kettle is connected with recycling can by discharging tube, and heating kettle is connected by first, second condenser with recycling can respectively with the top of pressure release kettle；When heating kettle and pressure release kettle are connected state, pressure release kettle can shed the pressure of increase in heating kettle, avoid system from depositing pressure to have an impact whole production process, while be avoided that and bring caffeine in condenser into, ensure recovery dichloromethane energy process safety, stably, be smoothed out.
Description
Technical field
The present invention relates to chemical technology field, and in particular to a kind of solvent recovery unit.
Background technology
China is the native place of tea tree, and Tea Industry development is flourishing long time.Fresh spring tea can be made into tealeaves and be drunk as drink, thick old
Tealeaves can obtain the high value added products such as caffeine, Tea Polyphenols through deep processing.At present, enterprise is extracting natural coffee from tealeaves
Coffee because when need to use dichloromethane to make extractant, the boiling point of dichloromethane is very low, be 40 DEG C or so, easily vaporization, through extraction
Afterwards, caffeine and dichloromethane mixture can realize separation by heating, after the caffeine remained is concentrated and dry i.e.
Caffeine product is obtained, the dichloromethane after vaporization can reuse by condensing and reclaiming.Due in heating process, vapour
The dichloromethane of change can increase the pressure in container, and the increase of pressure can make the caffeine of little particulate cold as dichloromethane enters
Condenser and be adhered on condenser inner wall.The loss of caffeine product had so both been caused, has also reduced the condensation effect of condenser,
If cleaning removes the caffeine being adhered on condenser inner wall not in time, then caffeine can block whole condensation pipe, make
It can not be normally carried out into production, or even potential safety hazard can be brought to production.Because dichloromethane belongs to moderate toxicity gas, therefore
If in the removing caffeine of removal process intermittent, then can both cause production inconvenience, also easily enter dichloromethane
In air, cause to waste and pollute environment.
The content of the invention
It is an object of the invention to provide a kind of solvent recovery unit that can guarantee that production process is safe and stable, be smoothed out.
To achieve the above object, the technical solution adopted by the present invention is：A kind of solvent recovery unit, heating kettle and pressure release kettle
Connected by relief tube, the bottom of pressure release kettle is connected with recycling can by discharging tube, and the top of heating kettle and pressure release kettle leads to respectively
First, second condenser is crossed to connect with recycling can.
It is using beneficial effect caused by above-mentioned technical proposal：When heating kettle and pressure release kettle are connected state, pressure release kettle
The pressure of increase in heating kettle can be shed, avoids system from depositing pressure and whole production process is had an impact, while be avoided that coffee
Because bringing into condenser, ensure recovery dichloromethane energy process safety, stably, be smoothed out.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
A kind of solvent recovery unit, as shown in figure 1, heating kettle 10 is connected with pressure release kettle 20 by relief tube 11, pressure release kettle
20 bottom is connected with recycling can 30 by discharging tube 21, and the top of heating kettle 10 and pressure release kettle 20 passes through first, second respectively
Condenser 41,42 connects with recycling can 30.Pressure release kettle 20 can shed the pressure of increase in heating kettle 10, the dichloro for vaporizing part
Methane enters in pressure release kettle 20, avoids system from depositing pressure and whole production process is had an impact, while be avoided that and bring caffeine into
In condenser, ensure recovery dichloromethane energy process safety, stably, be smoothed out.After dichloromethane enters in heating kettle 20,
The liquid of condensation can enter recycling can 30 from the discharging tube 21 of bottom, and uncooled dichloromethane enters the second condenser from top
42, after condensed, likewise enter and be recovered in recycling can 30.
For ease of adjusting and controlling the air pressure in heating kettle 10, the pipeline of the relief tube 11 is provided with choke valve 12.
To economize on resources and reducing cost, the volume of the heating kettle 10 is more than pressure release kettle 20.
