【摘要】 对于传统带式干燥机工作时存在耗能高、余热回收少、受热不均等问题，提出一种基于双段式节能理念的干燥机设计方案。采用管道短程化、梯度隔热、交错矩阵式风机排布、双级余热回收等方案对带式干燥机的管道及隔热系统、风机系统、预热和余热回收系统进行升级设计，使得干燥机的综合能耗降低了28.77%，余热回收效率达到62%，热风分布均匀性提升37%，为工业干燥装备绿色化升级提供了新的思路。更多还原

【Abstract】 Aiming at the problems of high energy consumption,low waste heat recovery,and uneven heating of traditional belt dryers during operation,a dryer design scheme based on the two-stage energy-saving concept is proposed.Schemes such as short-range piping,gradient heat insulation,staggered matrix fan arrangement,and two-stage waste heat recovery are adopted to upgrade the piping and heat insulation system,fan system,preheating system,and waste heat recovery system of the belt dryer. This upgrade results in a 28. 77% reduction in the dryer’s comprehensive energy consumption,an increase in waste heat recovery efficiency to 62%,and a 37% improvement in hot air distribution uniformity. The study provides a new idea for the green upgrading of industrial drying equipment.更多还原
