Summary of the invention
The object of the invention is to there is sediment discharging difficulty to solve existing methane-generating pit, need the technical barrier interrupting fermenting process, for people provide a kind of fermenting process continual and steady, sweathouse is without the need to large discharging, factor of created gase is high, air storage space is large, the precipitation fermentation integral type firedamp gas equipment that treating processes zero consumes energy.
The object of the invention is to be realized by following proposal.
Precipitation fermentation integral type firedamp gas equipment of the present invention, it is characterized in that described precipitation fermentation integral type firedamp gas equipment by between settling tank, sweathouse, discharge and liquid storage tank connect and compose successively, wherein, settling tank is connected with sweathouse by feed-pipe, sweathouse top is air chamber, air chamber is connected with airway, and sweathouse bottom is connected with between discharge by fermented liquid passage, is connected between discharge by liquid spill-way with liquid storage tank.
In such scheme, described settling tank is simple sedimentation pond or multifeed clarifier, and in multifeed clarifier, previous stage settling tank is connected with rear stage settling tank by feed liquid passage, and last step settling tank is connected with sweathouse by feed-pipe.
In such scheme, described sweathouse is single-stage sweathouse or multistage sweathouse, and in multistage sweathouse, previous stage sweathouse is connected with rear stage sweathouse by fermented liquid passage, and last step sweathouse is connected with between discharge by fermented liquid passage.
In such scheme, between described settling tank, discharge and the top of liquid storage tank is separately installed with removable cover.
In such scheme, described feed-pipe is from the horizontal by 45 ° of inclination angles.
Present invention employs settling tank (can be multistage as required) to process fermented feed liquid, by action of gravity, sediment deposits at the bottom of settling tank, and the feed liquid through preliminary acidifying, precipitation enters sweathouse (can be multistage as required) fermentation by feed-pipe.The biogas produced after fermentation is stored in air chamber, and along with methane quantity increases, biogas pressure increases, and by the feed liquid in sweathouse by between fermented liquid passage press-in discharge, the liquid level between discharge rises to liquid spill-way, finally flows into liquid storage tank.
The present invention utilizes gravity effectively to remove sediment, reduces the TS(total solids of feed liquid) concentration, alleviate aftertreatment pressure, sweathouse is without the need to interrupting the large discharging of fermentation, and large discharging completes in settling tank, ensure that the continuous service of methane-generating pit.Inclination angle is that the feed-pipe of 45 ° connects the middle part of settling tank and the bottom of sweathouse, achieves the function of waterpower plug-flow and stirring, after feed liquid is thoroughly fermented by sweathouse, discharges under biogas pressure effect, finally overflow to discharge pond.
In sum, the invention solves existing methane-generating pit and there is sediment discharging difficulty, need the technical barrier interrupting fermenting process, the precipitation fermentation integral type firedamp gas equipment pre-treatment precipitation provided for people is thorough, fermenting process is continual and steady, and sweathouse is without the need to large discharging, and factor of created gase is high, air storage space is large, and treating processes zero consumes energy.
