溫度場的分布和變化將直接影響整個系統的產氣量和產氣率。沼氣發酵受溫度的影響較大,高溫在夏季和秋季,天然氣生產,尤其是冬季冬季氣溫低,沼氣發酵原料的溫度通常低于10℃,沼氣生產受到嚴重影響,為了實現全年天然氣供應的需求,必須加強冬季和春季池保溫工作,其主要措施如下:
The distribution and change of temperature field will directly affect the gas production rate and gas production rate of the whole system. Biogas fermentation is greatly affected by temperature. In summer and autumn, the temperature of natural gas production, especially in winter, is low. The temperature of biogas fermentation raw materials is usually lower than 10 ℃. Biogas production is seriously affected. In order to meet the demand of natural gas supply throughout the year, it is necessary to strengthen the heat preservation work in winter and spring. The main measures are as follows:
(1)添加溫糞
(1) Add warm feces
加入人糞肥、馬糞或堆肥后的新鮮干草等發熱量原料,適當提高池液濃度至10 ~ 12%;
Add the raw materials of calorific value such as human manure, horse manure or fresh hay after composting, and properly increase the concentration of the tank liquid to 10 ~ 12%;
(2)增加風障,降低溫度消耗
(2) Increase wind barrier and reduce temperature consumption
沼氣池建在背風處或建在沼氣池的西北風壁上,也是降低溫度消耗的簡單方法;
The biogas digester is built on the leeward or the northwest wall of the digester, which is also a simple method to reduce the temperature consumption;
(3)秸稈覆蓋保溫
(3) Straw covering and heat preservation
用農作物秸稈或干草覆蓋池塘也可以減少溫度損失。
Covering ponds with crop straws or hay can also reduce temperature loss.
