Gas heating agent in heating agent circulation line (5) endotherm section (51) enters condenser (3) interior heating agent under blower (505) effect
The heat release section (52) of circulation line (5), the gas heating agent in heat release section (52) occur under the positive pressure that blower (505) generates
It liquefying and releases heat, the raw material in feedstock pipeline (6) absorbs the heat discharged when the liquefaction of gas heating agent and completes heating,
The gas heating agent occurs liquefaction in the heat release section (52) of the interior heating agent circulation line (5) of condenser (3) and is condensed into liquid heat
After matchmaker, heat absorption flowing water Valve (502), heat release inlet valve (503) and blower (505) are closed, opens heat absorption inlet valve (501)
With heat release flowing water Valve (504), flow back to liquid heat medium in heating agent surge tank (7), interior liquid rises to when heating agent surge tank (7)
When upper liquid level sensor (701) position, upper liquid level sensor (701) issues signal to controller, opens heating agent circulation pipe
Heat absorption flowing water Valve (502), heat release inlet valve (503) and blower (505) on road (5), continue with heating agent in evaporator
Biogas waste heat raw material is heated with heat absorption and exothermic circulation is carried out in condenser.
8. biogas slurry waste heat recycling system according to claim 7, which is characterized in that on the heating agent surge tank (7) also
Equipped with fluid infusion sensor (703) and fluid injection valve (704), when the liquid level of liquid heat medium is lower than fluid infusion sensor (703), fluid infusion
Sensor (704) issues signal to controller, prompts to open fluid injection valve after-teeming heating agent.
