目前,沼气输配系统还一直沿用过去的那种陈旧的安装配套方式,效果较差,主要原因有: 1.输气管道问题大。使用的管子直径都是7—8毫米的透明聚氯乙烯塑料软管,它既不防腐蚀,又不耐老化。裸露在室外的管道,一般使用3—5年后就老化破裂,安装在室内的这种管子,两年之后也开始扁缩,弯道处因管道凹陷而对沼气的压力降影响更为严重。沼气池离灯、炉具远,管道直径小,弯道多,灯炉具不能正常地发挥效率。
At present, the biogas transmission and distribution system has also been used in the past that the old installation and support methods, the effect is poor, mainly due to: 1. Gas pipeline problems. The tubes used are clear 7 to 8 mm clear PVC pipes, which are neither corrosion nor aging. Bare pipes exposed outside the home are aged and cracked after 3-5 years of use. Such pipes installed in the interior also begin to shrink after two years. The pressure drop of the biogas is more serious due to the depression of the pipe in the bend. Digester from the lamp, stove far, pipe diameter, bend more, light stove can not properly play an efficiency.
