堆肥尾气余热回用对生物滤池运行效果的影响
Impact of Reusing Waste Heat from Composting Off-gas on Operation of Biofilters
摘要
Abstract
Aerobic composting generates significant amounts of waste heat and odorous gases.To better utilize this waste heat and treat the odors,a spiral tube heat exchanger was designed within a biofilter to heat the filter media using composting exhaust heat.A control group(CK)without a heat exchanger was established to analyze the effects of different heat exchanger configurations on the biofilter's temperature increase,deodorization efficiency and energy-saving performance.The results showed that composting exhaust heat effectively raised the temperature of the biofilter media.The variable-pitch spiral tube heat exchanger achieved the best heating performance,increasing the media temperature by up to 6℃compared to CK under ambient temperatures of 17.2～23.7℃.The waste heat reuse also significantly enhanced deodorization efficiency,with the variable-pitch spiral tube heat exchanger demonstrating the highest ammonia removal rate of 90.35%,an improvement of up to 13.94%over CK.Additionally,the system improved media permeability and increased the abundance of odor-degrading microorganisms.Compared to traditional electric heating,this method saved 3.1 kWh·L-1 of filter media,demonstrating notable energy-saving benefits.Above results provided technical support for utilizing composting exhaust heat to enhance biofilter performance.关键词
