Description
Technical field
The present invention relates to chemical technology field, especially a kind of device being produced resin by distillation equipment.
Background technology
At present, resin processing technology is all adopt the method for vacuum distillation to produce resin substantially, common a kind of vacuum distillation plant preparing resin as shown in Figure 1, comprise distillation still 1, cooler 2, main distillate fraction storage tank 3, above-mentioned three kinds of equipment pass through pipeline communication, wherein the bottom of distillation still 1 is provided with bottom valve 9, the sidewall of distillation still 1 is provided with oil-in 7 and oil-out 6, oil-in 7 connects inlet valve 8, oil-out 6 connects oil return valve 5, oil pipe 10 is provided with in distillation still 1 inside between oil-in 7 and oil-out 6, its principle is that rosin fat liquid injects in distillation still 1, heating oil enters distillation still 1 by inlet valve 8 from oil-in 7 and heats rosin fat liquid, and from oil-out 6, oil return valve 5 is discharged outside distillation still 1, after rosin fat liquid in distillation still 1 is heated, flash to gas and enter cooler 2 from distillation still 1 top, after cooler 2 cools, become liquid enter main distillate fraction storage tank 3, obtain resin, remaining gas then enters vacuum tank by valve 4, owing to just relying on deep fat heating, there is the problem that rosin preparation time is long in this vacuum distillation plant, rosin preparation time is long then can cause resin product colour to deepen, thus affects resin quality.
Summary of the invention
Technical problem to be solved by this invention improves the evaporation efficiency of rosin fat liquid, shortens rosin distillation time.
In order to solve the problem, the technical solution adopted in the present invention is: this nitrogen vacuum distillation plant, comprise distillation still, cooler and main distillate fraction storage tank, described distillation still is communicated with described cooler by pipeline, described cooler is communicated with described main distillate fraction storage tank by pipeline, heating tube is provided with in described distillation still, described heating tube respectively with the oil-in of described distillation still, oil-out is communicated with, the bottom of described distillation still is provided with Drainage pipe, described Drainage pipe is provided with bottom valve, described main distillate fraction storage tank is provided with discharge duct, described discharge duct is provided with air bleeding valve, described Drainage pipe is connected with gas ducting, described gas ducting is provided with pressure-reducing valve and check-valves successively.
In technique scheme, technical scheme can also be more specifically: described oil-in is connected with inflow pipeline, and described inflow pipeline is provided with inlet valve; Described oil-out connects flowline, and described flowline is provided with oil return valve.
Further: the bottom of described main distillate fraction storage tank is provided with exhaust-valve.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
The present invention by installing nitrogen pipeline, source of the gas control valve, check-valves etc. additional bottom distillation still, under vacuum distillation state, suitable adjustment nitrogen pressure, allow nitrogen by entering in distillation still bottom distillation still, nitrogen is fully mixed with rosin fat liquid, reaches gas-liquid and rise effect altogether, thus reach the vaporization of quickening material and evaporation, shorten distillation time, effectively improve the color of resin and save production cost.
