Biogas fermentation is also known as anaerobic digestion, anaerobic fermentation, refers to organic substance（Such as people and animals' poultry manure, stalk, weeds
Deng）Under certain moisture, temperature and anaerobic condition, by the catabolism of each quasi-microorganism, methane and dioxy are ultimately formed
Change the flammable mixed gas such as carbon（Biogas）Process.
Fixed ledge hydraulic type biomass pool has three kinds of cylindrical shape, spherical shape and elliposoidal pond types.The pond body top of this pond type
Gas chamber completely encloses, and with the continuous generation of biogas, biogas pressure accordingly improves.This air pressure constantly increased forces biogas
A part of feed liquid in pond is entered in the water pressure chamber communicated with pond body so that the liquid level raising in water pressure chamber.So, hydraulic pressure
Liquid level between as soon as just produces a water-head with the liquid level in biomass pool body, this water-head is called " hydraulic pressure "（Namely U
The numerical value that shape pipe methane pressure gage is shown）.During with gas, biogas switch is opened, and biogas is discharged under hydraulic pressure；When biogas is reduced,
The feed liquid of water pressure chamber is returned in pond body again so that water-head constantly declines, and causes biogas pressure is also corresponding therewith to reduce.This profit
With part feed liquid vibration back and forth, hydraulic pressure is caused to change repeatedly to store and discharge the pond type of biogas, just referred to as hydraulic methane
Pond.
