Analysis on pickling and pickling waste liquid treatment technology for supercritical oncethrough boiler

Abstract

Abstract:

Pickling process of a oncethrough boiler is introduced and analyzed. The pickling takes EDTA-H2SO4 plus surfactant and Captax corrosion inhibitor and pickling effect is satisfying.The washing water is filtered and sedimentate and pickling wastewater is degraded and evaporated.Improvement is made on the base of original wastewater treatment method, and the treated waste liquid can meet the national emission standards.

Key words:

supercritical, oncethrough boiler, pickling, washing water, pickling waste liquid treatment, applicability
