AI Technical Summary
Existing waste heat recovery devices for bathing wastewater coupled with air compressors suffer from high energy consumption, reliance on external brick factory steam, and insufficient system stability.
The system employs a wastewater filtration system, a cold water heating system, and a bath water supply system. It utilizes external preheating, including adding a hair filter before the wastewater drain pipe, using scale inhibitors to prevent scale formation, and installing a scale inhibitor before the air compressor heat recovery unit to recover the high-temperature lubricating oil heat from the air compressor. The system also uses a closed-loop self-cleaning heat exchanger and the air compressor heat recovery unit to heat tap water to a suitable temperature.
Significant economic and emission reduction benefits have been achieved, reducing reliance on brick factory steam and improving the stability and energy efficiency of the bathing water supply system.
