Abstract
The utility model provides an ethanol distillation recovery device, comprising an ethanol distillation tower, a primary condenser, an after-condenser, and an ethanol storage pot which are connected in series in order through a pipe. The utility model is characterized in that the bottom of the ethanol distillation tower is provided with a steam inlet and a steam outlet; a return conduit is disposed at the outlet of the primary condenser and the upper end of the ethanol distillation tower; a flow meter is disposed on the return conduit. With the arrangement of the return conduit between the primary condenser and theethanol distillation tower, the utility model is advantageous in that a secondary distillation of the backflow liquid is achieved; the distillation recovery total of the ethanol in a unit time is improved by 50-63%; the recovery concentration of ethanol reaches to over 94%.
Description
Technical field
The utility model relates to the ethanol distillation retrieving arrangement.
Background technology
(full name: it is refining etc. to widely apply ethanol to carry out finished product in production diene alcohol ketone acetic ester), simultaneously the ethanol in the effluent discharge is distilled recovery set usefulness, in order to reducing production costs for diene.The structure of existing alcohol recovering device is: ethanol distillation tower, primary condenser, after-condenser, ethanol hold-up vessel constitute by the pipeline series connection successively, and it is slow that ethanol distillation reclaims speed, and it is low that ethanol reclaims concentration, has only 90-94%.
Summary of the invention
Reclaim concentration and organic efficiency in order to improve ethanol, the utility model proposes the ethanol distillation retrieving arrangement.
For this reason, the technical solution of the utility model is: the ethanol distillation retrieving arrangement, constitute by the pipeline series connection successively by ethanol distillation tower, primary condenser, after-condenser, ethanol hold-up vessel, the bottom of ethanol distillation tower is provided with steam inlet and vapour outlet, it is characterized in that: be provided with return line in the outlet of primary condenser and the upper end of ethanol distillation tower, under meter is housed on the return line.
Beneficial effect: owing to increased return line between primary condenser and ethanol distillation tower, realize the second distillation of phegma, unit time ethanol distillation yield has improved 50-63%, and ethanol recovery concentration has reached more than 94%.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, it is as follows to further describe the utility model: the ethanol distillation retrieving arrangement, form by ethanol distillation tower 1, primary condenser 2, after-condenser 3, ethanol hold-up vessel 4, the bottom of ethanol distillation tower is provided with steam inlet 12 and vapour outlet 11, ethanol distillation tower 1 top is provided with pipeline 5 and is connected to primary condenser 2, the outlet of primary condenser 2 is provided with pipeline 6 and is connected to after-condenser 3, the outlet of after-condenser 3 is connected with ethanol hold-up vessel 4 by pipeline 7, and pipeline 6 is provided with under meter 8; Also be provided with return line 10 in the outlet of primary condenser 2 and the upper end of ethanol distillation tower 1, under meter 9 is housed on the return line 10.In the such scheme, return line 10 is preferably introduced down from the tower cap of ethanol distillation cat head.
