Black liquor (containing a large amount of lignin and alkalis, strongly alkaline and with a complex composition) generated during the papermaking pulping process is the most important heat exchange target. Spiral plate heat exchangers can be used to heat or cool black liquor, white liquor, and green liquor. Specifically, this includes:
Black liquor waste heat recovery: The dilute black liquor produced in the alkali recovery evaporation section can be recycled through a heat exchanger to recover its waste heat for use in heating process water, equipment heating, and pulp preheating in the papermaking workshop, significantly reducing steam and electricity consumption.
Warm water waste heat utilization: The warm water (45-50℃) generated during the alkali recovery evaporation process, which was previously wasted through cooling towers, can be recovered through heat exchange equipment to increase the winter production water supply temperature (from less than 20℃ to 25-30℃), reducing overall system energy consumption.
