Abstract
An anaerobic digestion system may include a material grinding/pulping portion, a hydrolysis portion arranged downstream of the grinding portion, a multiple chamber anaerobic reactor arranged downstream from the hydrolysis portion and including a gas collection and reintroduction system, a collection system for collecting digestate and gas from the anaerobic reactor.
Claims20
A system comprising:
- a grinding/pulping device configured to reduce a material particle size of feedstock fed into the grinding/pulping device, wherein the grinding/pulping device includes a catalyst-input portion;
- a hydrolysis portion configured to receive a liquid/solid slurry that includes organic solids in a liquid, wherein the hydrolysis portion is arranged downstream of the grinding/pulping device;
- an anaerobic reactor arranged downstream from the hydrolysis portion, wherein the anaerobic reactor includes an agitator, and wherein the agitator includes a gas reintroduction system configured to reintroduce an effluent gas to agitate a content of the anaerobic reactor;
- a digestate collector configured to collect digestate from the anaerobic reactor;
- and
- an output-gas collector configured to collect an output gas from the anaerobic reactor.
3 more elements
A system comprising:
- an input system that includes a feeding conveyor and a feeding pump, wherein the feeding conveyor is configured to input a solid feedstock, and wherein the feeding pump is configured to input a sewage liquid waste;
- a grinding/pulping device configured to reduce a material particle size of feedstock fed into the grinding/pulping device, wherein the grinding/pulping device is arranged downstream from the input system;
- a hydrolysis portion configured to receive a liquid/solid slurry that includes organic solids in a liquid, wherein the hydrolysis portion is arranged downstream of the grinding/pulping device;
- an anaerobic reactor arranged downstream from the hydrolysis portion, wherein the anaerobic reactor includes an agitator, and wherein the agitator includes a gas reintroduction system configured to reintroduce an effluent gas to agitate a content of the anaerobic reactor;
- a digestate collector configured to collect digestate from the anaerobic reactor;
- and
- an output-gas collector configured to collect an output gas from the anaerobic reactor.
4 more elements
A system comprising:
- a hydrolysis portion configured to receive a liquid/solid slurry that includes organic solids in a liquid;
- an anaerobic reactor arranged downstream from the hydrolysis portion, wherein the anaerobic reactor includes an agitator, wherein the agitator includes a gas reintroduction system configured to reintroduce an effluent gas to agitate a content of the anaerobic reactor, wherein the anaerobic reactor includes a first compartment and a second compartment, wherein the gas reintroduction system is configured to collect an effluent gas from the first compartment to form first-compartment effluent gas and reintroduce the first-compartment effluent gas into the second compartment, and wherein the gas reintroduction system is further configured to collect an effluent gas from the hydrolysis portion to form hydrolysis-portion effluent gas and reintroduce the hydrolysis-portion effluent gas into the first compartment of the anaerobic reactor;
- a digestate collector configured to collect digestate from the anaerobic reactor;
- and
- an output-gas collector configured to collect an output gas from the anaerobic reactor.
2 more elements
A system comprising:
- a hydrolysis portion configured to receive a liquid/solid slurry that includes organic solids in a liquid;
- an anaerobic reactor arranged downstream from the hydrolysis portion, wherein the anaerobic reactor includes an agitator, and wherein the agitator includes a gas reintroduction system configured to reintroduce an effluent gas to agitate a content of the anaerobic reactor;
- a digestate collector configured to collect digestate from the anaerobic reactor, wherein the digestate collector includes a tank;
- and
- an output-gas collector configured to collect an output gas from the anaerobic reactor, wherein the output-gas collector includes a gas-collecting membrane that defines a space above the tank.
