Title:
ALCOHOL VAPOUR SEPARATION APPARATUS FOR USE IN NITROCOTTON PRODUCTION PROCESS
Document Type and Number:
WIPO Patent Application WO/2019/028566
Kind Code:
A1
Abstract:
An alcohol separation apparatus, particularly an alcohol vapour separation apparatus for use in a nitrocotton production process, comprising a mixed liquid delivery pump (1), a slag discharge pump (2), an alcohol storage cabinet (3), a dryer (4), a condenser (5), an alcohol delivery pump (6), a vapour heating and separation cabinet (7), and a recovery cabinet (8), the vapour heating and separation cabinet (7) comprising a vapour coil (71), a high floating ball limit (72 ), a low floating ball limit (73), a residue discharge valve (74), and a temperature controller (75), the vapour coil (71) being arranged in the middle lower part of the vapour heating and separation cabinet (7), the high floating ball limit (72) being arranged at 2/3 on the inner wall of the vapour heating and separation cabinet (7), the low floating ball limit (73) being arranged at 1/4 on the inner wall of the vapour heating and separation cabinet (7), the residue discharge valve (74) being arranged at the bottom of the lower end of the vapour heating and separation cabinet (7), and the temperature controller (75) being arranged in a middle lower position on one side of the vapour heating and separation cabinet (7). The advantages of the separation apparatus are the simple design, a vapour coil (71) being used to heat the mixed liquid so that the vapour does not need to directly contact the mixed liquid, and safe operation, preventing the occurrence of accidents.
