摘要
设计了一种太阳能沼气互补型热水器系统。该系统充分利用农村洗浴水、烟气的余热,采用重力热管回收大气的热量对沼气池加热,增加产气率。当太阳能不能提供足够的热量时,用沼气燃烧补充。介绍该系统的原理与流程,结合实例探讨供需热量的平衡。将该系统与太阳能热水器、电热水器及空气能热水器进行经济性对比,该系统经济效益明显。
A solar biogas complementary water heater system is designed. This system makes full use of the waste heat of rural bathing water and flue gas and uses gravity heat pipes to recover the heat of the atmosphere to heat the biogas digester,increasing the gas production rate. When solar energy cannot provide enough heat,it is replenished with burning biogas. The principle and process of the system are introduced,and the balance of heat supply and demand is discussed with examples. Comparing the economy of this system with solar water heaters,electric water heaters and air energy water heaters,the economic benefit of this system is obvious.
