Description

秸秆沼气工程发酵罐Straw Biogas Project Fermentation Tank

技术领域 technical field

本实用新型涉及一种生物能源领域的沼气发酵罐，尤其涉及一种秸秆沼气工程发酵罐。The utility model relates to a biogas fermentation tank in the field of biological energy, in particular to a straw biogas engineering fermentation tank.

背景技术 Background technique

农作物秸秆由于其来源广泛，价格低廉，收集方便，而成为生物质能源利用的焦点。而秸秆沼气发酵普遍存在结壳的问题。秸秆比重轻，进入发酵罐后易上浮，加上其流动性差，秸秆搅拌技术不成熟，而逐渐形成硬壳。这样也就形成了秸秆沼气的第二个难题——出料难。现在通常采用沼气工程发酵罐来源于适用于粪污原料的发酵罐的改造。由于秸秆与粪污在物理化学等方面的差异，造成了发酵罐进料、出料、搅拌、浓度等各个方面的不适用。Crop straw has become the focus of biomass energy utilization due to its wide source, low price and convenient collection. However, there is a common problem of crusting in straw biogas fermentation. The specific gravity of the straw is light, and it is easy to float up after entering the fermentation tank. In addition, its fluidity is poor, and the mixing technology of the straw is immature, and a hard shell is gradually formed. This also forms the second problem of straw biogas - the difficulty of discharging. Now the biogas engineering fermenter is usually used from the transformation of the fermenter suitable for manure raw materials. Due to the differences in physical and chemical aspects between straw and manure, it is not suitable for various aspects such as feeding, discharging, stirring, and concentration of the fermenter.
