Abstract: There are few commercialized compost reactors and some applied reactors have many problems,that is,reacting materials mix unevenly and waste materials is easy to produce odor during the compost process.Therefore,an organic solid wastes compost equipment with mixed oar and layer of adsorption is designed.The main material of this equipment is made of organic glass or stainless steel,which can contain 100 L waste material.And this equipment contains insulating layer,air collecting layer,filler layer of adsorption,aixs of rotation,intaking buffer layer,mixed oar,intake duct,drainage duct,material outflowing,air outlet,moving top cover and the compost warehouse formed by the space held in the inner wall of insulating layer.When composting the kitchen wastes,the average ventilation rate should be 68.19 m³/d,the maximum range of gas flowmeter rate 0.15 m³/min,the air volume provided by the fan 8.4 m³/h,and the total pressure 2×10³ Pa,the diameter of agitating shaft of reactor 30 mm,the shaft diameter of output shaft of transmission 15mm,the external diameter 25 cm,the effective height of agitating shaft 57 cm,the motor rated power of mixing equipment 3.0 kW.This equipment has these potential advantages,such as mixing reacting materials evenly and being free of odor.

摘要： 针对目前商品化的堆肥反应器较少,且个别应用的反应器亦存在着反应物料多混合不均匀、易产生臭气等问题,设计了一种带有搅拌齿和吸附层的有机固体废物堆肥反应器。该反应器主体材料用有机玻璃或不锈钢制成,可装堆料100 L。该装置包括保温层、集气层、吸附填料层、进气缓冲层、旋转轴、搅拌齿、进气管、排液管、出料口、排气口、活动盖连接及由保温层内壁包容的空间所构成的堆肥仓。实际进行厨余垃圾堆肥时,平均通风量应为68.19 m³/d;气体流量计的最大量程应为0.15 m³/min;风机应提供的风量为8.4 m³/h,全压为2×10³ Pa。反应器搅拌轴的直径为30 mm,变速器输出轴的轴径取15 mm,搅拌齿的外径取25 cm,搅拌轴的有效高度为57 cm,搅拌设备的电机额定功率为3.0 kW。该装置具有能使反应物料混合均匀、避免产生臭气等的潜在优点。
