Abstract

The invention provides a tandem alcohol solvent recovery device which comprises filters, washing liquid tanks, condensers, liquid collection tanks and vacuum pumps, wherein each filter is connected to one corresponding washing liquid; the plurality of sets of washing liquid tanks are connected in parallel to the condenser 1; the condenser 1 is connected with the liquid collection tank 2 and condenser 3; the condenser 3 is connected with the condenser 4; the condenser 4 is connected with the liquid collection tank 2, vacuum pump 5 and vacuum pump 6; and the vacuum pump 5 and vacuum pump 6 are connected in parallel to a silencer 7.By reasonably adopting the parallel / tandem structural design in equipment connection, the device reduces the equipment configuration, prolongs the air flow process, and enhances the cooling effect; and by transferring all the condensers to the negative pressure part, the device enhances the recovery amount of the directly recoverable alcohol solvent of the negative pressure part, so that the alcohol solvent content of the positive pressure part after the vacuum pumps is very low, and the residual alcohol does in the positive pressure part does not need to be collected.

Description

technical field [0001] The invention relates to an organic solvent recovery technology, in particular to a serial alcohol solvent recovery device. Background technique [0002] The production of modified starch by alcohol solvent method is an important method for producing modified starch. It has the characteristics of high reaction efficiency, uniform reaction and no environmental pollution. However, in the existing alcohol solvent method to produce modified starch in the reactor, the ratio of starch and alcohol consumption is 1:2~3. Immediately considering the recovery and recycling of alcohol solvent, it needs to consume 0.3 -0.5 tons of alcohol, so in the production of modified starch by the existing alcohol solvent method, there are technical defects such as that the alcohol recovery efficiency is not high, and the cleanliness of the partially recovered alcohol solution is poor and cannot be directly used. [0003] At the same time, in the existing alcohol solvent meth...
