一、沼气池和太阳能的综合利用建起沼气池的农户,常因早春或晚秋气温低,产气少而苦恼。这里向你介绍一种沼气池和太阳能的综合利用的方法,可以解决这个问题。在沼气池上边或旁边,建一个小型太阳能热水器,方法是:用砖或土坯垒一个方圆2米的小型浴室,上边用1—1.5毫米厚的铁板焊一个一平方米大的方型水箱,坐北朝南,北高34厘米,南高17厘米,上面盖一块5毫米与水箱同样大小的平板玻璃,四边用腻子腻好。水箱后面上方焊一进水管(也叫溢水管),前面靠底部焊一出水管并安有阀门和喷头,箱里面涂上沥青或黑漆,以提高吸光集热能力,箱底外和四周用锯末或柴草围起来保温。这样的太阳能热水器,夏季
First, the comprehensive utilization of digesters and solar energy Households built digesters, often due to early spring or late autumn, the temperature is low, less gas and distressed. Here to introduce you to a comprehensive utilization of biogas digesters and solar energy methods that can solve this problem. On or beside the digester, build a small solar water heater by brick or adobe with a 2-square-meter small bathroom with a 1-square-meter square tank topped with 1-1.5-mm thick iron plate, Sit south, north 34 cm high, 17 cm high south, covered with a 5 mm above the tank and the same size of glass, putty on both sides with a good. A water inlet pipe (also called an overflow pipe) is welded on the top of the water tank. A water outlet pipe is welded on the front and a valve and a spray head are arranged in the tank. The asphalt or black paint is coated inside the tank to enhance the light absorption and heat collection capacity. Or firewood enclosed to keep warm. This solar water heater, summer
