有些沼气用户在春节前后给沼气池换料,换后一二个月点不着火,直到次年5月下旬才能日做三餐。果真是“换了还不如不换”吗? 根据本人对150多个三结合户用沼气池的调查,秋季换料才是保证低温季节多产气的关键措施。一户喂猪2～5头,不再换料的池到10月中下旬开始不够日做三餐用气,下年5月下旬麦收前才够用;而9月下旬换料的池,日做三餐的时间一直延续到12月中下旬,翌年春季3月中下旬又恢复到日做三餐的水平,全年仅有三个月气不够用。秋换料和冬换料相比,沼气日做三餐的时间一年多出4个月。 9月下旬换料,环境温度一般在20℃左右,换料过程不影响池温,从投接种物到正常产气
Some biogas users before and after the Spring Festival to digester refueling, one or two months after the change of ignition, until the following year in late May to make three meals a day. Is it really better to change it? According to my survey of more than 150 triple combined biogas digesters, the autumn refueling is the key measure to ensure that more gas is produced in the cold season. A pig feed 2 to 5, no longer refueling pool to mid-to-late in October to do enough gas to make meals, the late May next year wheat harvest before enough; and in late September refueling pool, Japan Do three meals a day until mid to late December, the following spring in mid-March again to restore to the level of three meals a day, only three months of the year is not enough. Autumn refueling and winter refueling, biogas to do more than three meals a day more than four months. In late September refueling, the ambient temperature is generally about 20 ℃, the refueling process does not affect the pool temperature, from the inoculum to the normal gas production
