Structural Design and Energy-Saving Analysis of Shoe Glue Drying Equipment Based on Air Source Heat Pump and Variable Frequency Technology

摘要: 针对制鞋行业传统电加热烘干设备能耗高、车间温湿度环境恶劣及存在消防隐患等痛点，本文研发了一种基于空气能热泵与变频技术的新型智能鞋胶烘干设备。基于逆卡诺循环原理，设计了内外物理隔离的双风道热力循环系统，采用定制化9 kW级微通道冷凝器实现高效放热。针对传统烘干流场不均的问题，引入贯流风机并依据流体力学“有效管长”原则加装整流风管，将无序紊流转化为稳定二维层流，使出风口风速极差小于0.05 m/s。实测及节能分析表明：单组热泵烘干模块较传统电热模块直接运行能耗降低达62.0%；结合热泵“一机两用”特性，每日可产生相当于20.6 kWh电量的间接降温收益；单组模块年度二氧化碳减排量约为12.3吨。设备在显著提升鞋胶热活化均匀度与良品率的同时，大幅降低碳排放量，为制鞋企业绿色转型提供技术支撑。

Abstract: Addressing the pain points of high energy consumption, harsh temperature and humidity environment, and fire hazards in traditional electric heating drying equipment in the shoe manufacturing industry, this paper develops a novel intelligent shoe glue drying equipment based on air source heat pump and variable frequency technology. Based on the reverse Carnot cycle principle, a dual-duct thermal circulation system with internal and external physical isolation is designed, and a customized 9kW microchannel condenser is used to achieve efficient heat release. To address the problem of uneven flow field in traditional drying, a cross-flow fan is introduced, and a rectifier duct is installed according to the “effective pipe length” principle of fluid mechanics, transforming disordered turbulent flow into stable two-dimensional laminar flow, resulting in an outlet air velocity difference of less than 0.05 m/s. Actual measurements and energy-saving analysis show that a single heat pump drying module reduces energy consumption by up to 62.0% compared to traditional electric heating modules. Combined with the “dual-purpose” characteristic of heat pumps, it can generate indirect cooling benefits equivalent to 20.6 kWh of electricity per day. The annual CO2 emission reduction per module is approximately 12.3 tons. The equipment significantly improves the uniformity of thermal activation and yield of shoe adhesives while substantially reducing carbon emissions, providing technical support for the green transformation of footwear manufacturing enterprises.
