AI Technical Summary

Technical Problem

During the production of compound fertilizer, a large amount of recoverable heat energy and purified condensate resources in the waste gas are not being fully utilized. Existing purification devices only focus on purification effects and ignore resource recovery.

Method used

Plate heat exchangers and condensation tanks are installed in the waste gas purification device to recover heat energy from the waste gas and form condensate before and after purification, respectively. Multi-stage purification treatment is carried out in combination with dust pre-sedimentation device, spray tower and biodegradation tank.

Benefits of technology

It enables the reuse of heat energy and condensate in waste gas, improves the recycling rate of resources, reduces production costs and reduces environmental pollution.
