Electrolyte heating method and device

Abstract

The invention relates to an electrolyte heating method and device, and belongs to the technical field of chemical engineering. The method comprises the following steps of preheating, heating, heat preserving, and temperature compensation. The electrolyte heating device comprises an electrolyte conveying pipe and multiple heaters. The liquid conveying pipe is used for conveying an electrolyte to anelectrolyte to an electrolyte injection room from an electrolyte storage room, the heaters are used for heating the multiple portions of the electrolyte conveying pipe, the portions comprise the electrolyte conveying pipe at the connecting position of the electrolyte storage room and the electrolyte injection room, a front half segment electrolyte conveying pipe of the electrolyte injection room,a rear half segment electrolyte conveying pipe of the electrolyte injection room and an electrolyte conveying pipe on an electrolyte injection machine electrolyte outlet. Through segmented heating and heat preservation, heat energy is effectively used, electrolyte temperature stability is maintained, a preheating device is started for stabilizing the electrolyte and room temperature difference, and the phenomenon that due to the large temperature difference, fluid resistance or bubbles are generated is avoided.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to an electrolyte heating method and device. Background technique [0002] In battery production, it is necessary to heat the electrolyte to reduce the storage time after the battery is injected and improve the wetting ability of the electrolyte. [0003] Most of the heating equipment adopts oven-type heating to increase the temperature of the electrolyte. The oven-type heating has the following disadvantages: the heating section is relatively small, and after the electrolyte flow rate increases, the heating temperature is unstable and the control speed is slow; the oven occupies a large area and cannot Effective use of space, large heat loss, which is not conducive to energy saving in production; the oven temperature rises slowly, and the oven needs to be opened in advance before each production, and the production requirements can only be met after the temperature is sta...
