NMP steam condensate recovery system for lithium battery production

Abstract

The invention discloses an NMP (N-Methyl Pyrrolidone) steam condensate recovery system for lithium battery production, which comprises a shell placed above the horizontal ground, a first partition plate and a second partition plate are arranged on the inner side of the shell, and the first partition plate and the second partition plate sequentially divide the interior of the shell into a steam inlet layer, a collection layer and a condensation layer from bottom to top; the first gear is in shaft connection with the inner side of the first partition plate, the outer side of the first gear is in meshed connection with a second gear, and a cam is fixed to the outer side of the shaft end of the second gear; and the movable plate is in shaft connection with the outer wall of the heat exchange tube. According to the NMP steam condensate recovery system for lithium battery production, the condensation pipe can be driven by steam to vibrate in multiple directions, so that the condensation effect of the steam is effectively improved, meanwhile, heat in the steam can be recycled, secondary heating of condensate is achieved, subsequent secondary rectification is facilitated, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of lithium battery processing, in particular to an NMP steam condensate recovery system for lithium battery production. Background technique [0002] The coating machine is an indispensable and important equipment in the production process of lithium batteries. During the use of the coating machine, a large amount of NMP steam will be generated. In order to avoid environmental pollution and reduce production costs, it is necessary to use an NMP steam condensate recovery device for NMP The steam is condensed and recovered, but the existing NMP steam condensate recovery device for lithium battery production still has some shortcomings. [0003] For example, the publication number is CN212854693U, a kind of NMP steam condensate recovery device used in lithium battery production, which can expand the area of ​​cooling condensate operation, improve the efficiency of cooling condensate operation, and facilitate th...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a kind of NMP steam condensate recovery system for lithium battery production, to solve the inconvenience of the NMP steam condensate recovery device for lithium battery production in the market to recycle the heat in the NMP steam proposed by the above-mentioned background technology, As a result, the pressure of heat exchange in the subsequent condensation process is increased. At the same time, the structure of the condensation system is single, and the condensation time and effect of the steam are limited, thereby reducing the efficiency of NMP steam condensate recovery.
