Description
Technical field
The present invention relates to device for absorbing tail gas, relate in particular to the device for absorbing tail gas in the rosin esterification technical process.
Background technology
Rosin ester is one of product important in the rosin reprocessing product, in process of production, the small-molecule substance that contains in the rosin can volatilize, be discharged to from reactor that condensation becomes liquid or semisolid thick substances the process of pipeline, in the course of time, the thick substances accumulation, easy blocking pipe, simultaneously, after esterification of rosin esterification is complete, in order to improve the product quality of rosin ester, reactor is vacuumized operation, small-molecule substance in the esterification products is wherein thoroughly separated, existing technology is to add a vavuum pump at the reactor discharge duct, rosin esterification tail gas is retracted in the oil-water separation tank separates, equally in vacuum, the small-molecule substance of extracting out also can be condensed into liquid or semisolid thick substances, cause the obstruction of vacuum-pump line, the vacuum that affects vavuum pump descends, and causes that not only the rosin esterification product is extracted impurity out incomplete, reduce the quality of esterification products, and the service life that can also reduce vavuum pump.In order to address the above problem, the utility model provides the rosin esterification device for absorbing tail gas, can solve the problem that esterification of rosin esterification produces the condensation blocking pipe of small-molecule substance, simultaneously, small-molecule substance wherein can be separated, reduce the discharging of the waste oil in the oil-water separation tank, reached the purpose of environmental protection, cleaner production.
Summary of the invention
For addressing the above problem, the rosin esterification device for absorbing tail gas that provides of the present utility model, comprise: reactor, blast pipe, surge tank, vavuum pump, tube connector, the alcohol tourie, oil-water separation tank forms, reactor is connected with surge tank through blast pipe, in the surge tank back, respectively with the alcohol tourie, vavuum pump links to each other, it is characterized in that: vavuum pump and tube connector are connected in parallel between surge tank and the alcohol tourie, blast pipe is connected in surge tank top, the top of surge tank is the triangular funnel shape of a back-off, purpose can access sufficient condensation when being blast pipe tail gas out by surge tank, can prevent from stopping up the purpose of exhaust outlet, the liquid that tail gas condensing obtains or semisolid thick substances, then rest in the surge tank, the surge tank outlet is in the surge tank middle and upper part, and its mouth of pipe protrudes from the inwall of surge tank, and purpose is to prevent that liquid or semisolid thick substances that tail gas condensing obtains from stopping up outlet when the buffering tank skin flow to the surge tank bottom.
In order to solve the problem of small-molecule substance condensation blocking pipe, described blast pipe is insulating tube, so that tail gas is discharged to not condensation in the surge tank process at blast pipe.In the process of producing, close the front valve of vavuum pump, valve responds still, surge tank, tube connector, alcohol tourie, the oil-water separation tank of opening tube connector form a path, the small-molecule substance that reaction produces, the at first condensation by surge tank, major part is condensed into liquid or semisolid thick substances, and rest in the surge tank, the uncondensable tail gas of part, then enter into the alcohol tourie, absorbed by alcohol, remaining a small amount of insoluble tail gas then enters into oil-water separation tank to be separated.After esterification is complete, this closes the valve of tube connector, open the front valve of vavuum pump, so that reactor, surge tank, vavuum pump, alcohol tourie, oil-water separation tank form a path, the small-molecule substance of extracting out is by the condensation of surge tank, be condensed into liquid or semisolid thick substances, rest in the surge tank, the uncondensable tail gas of part, then be retracted to the alcohol tourie by vavuum pump and absorbed by alcohol, remaining a small amount of insoluble tail gas then enters into oil-water separation tank to be separated.
The utility model can solve the problem that esterification of rosin esterification produces the condensation blocking pipe of small-molecule substance, the thick substances that in surge tank, obtains simultaneously, can reclaim use, also reduced the blockage problem of vavuum pump, improved its service life, also reduce the discharging of the waste oil in the oil-water separation tank, reached the purpose of environmental protection, cleaner production.
