Description
Technical field
The present invention relates to field of garbage disposal, particularly, are related to a kind of anaerobic reactor.
Background technology
The impurity such as the chilli seed digested, portion are difficult to containing some fine sands and glass dregs and anaerobic fermentation in kitchen garbage raw material
Impurity is divided to bond with kitchen garbage organic matter even to inlay together, existing pretreatment desanding technology is difficult to a kitchen garbage original
Sand grains in material thoroughly removes, and remaining sand grains enters anaerobic reactor with organic ink.Organic matter is micro- in anaerobic reactor
Biodegradation is converted into biogas, the part guanite particle formed in sand grains and anaerobic digestion process then since density is larger,
Anaerobic reactor bottom and periphery are constantly deposited；Meanwhile kitchen garbage anaerobic reactor easily forms stirring dead zone and sediment outflow difficulty
Greatly, longtime running can cause dischargeable capacity in reactor constantly to reduce, and greatly reduce the efficiency of anaerobic fermentation, when serious even
It will appear line clogging, the situation that anaerobic reaction mechanical stirrer can not be run.
Domestic kitchen garbage anaerobic reactor is mostly by the way of " lower charging top discharge ".Anaerobic reactor designs 1
Center blender is stirred, and the main function of blender is to promote being sufficiently mixed, therefore stirring intensity for material and microorganism
Less；Sand grains in slurry is since density is larger, constantly to anaerobic reactor bottom deposit, bottom design sediment outflow pipe, periodically into
Row sediment outflow, so as to achieve the purpose that desanding inside anaerobic reactor.
Due to the volume about 1000m of anaerobic reactor used in current anaerobic fermentation of kitchen waste project3~5000m3。
The volume of such reactor is larger, and the phenomenon that difficulty is big is mixed with zymotic fluid there is organic matter.Though reactor bottom is equipped with row
Sandpipe, but sand grains is irregularly distributed in bottom, it is impossible to desanding mouth effectively is pooled to, desanding effect is undesirable, longtime running meeting
Causing sand grains, constantly siltation forms dead zone in tank skin bottom, eventually leads to reactor dischargeable capacity and constantly reduces and fermentation efficiency
It reduces.To ensure the efficient stable operation of anaerobic reactor, the measure of the thorough clear tank of every few years can only be taken now, and clear tank
Not only difficulty is big, time-consuming, costly, can also influence entire project and run well.
