Fermentation system having strainer assembly

摘要

A fermentation system for production of biogas from solid organic material, the system including at least one fermentation reactor. The fermentation reactor includes a vessel (37) for housing a feed mixture having liquid and solid particles and an outlet port (44), a strainer assembly (33) at the outlet port for filtering processed feed mixture from the vessel, and a biogasification reactor (37) in fluid communication with another fermentation reactor, the other fermentation reactor configured to produce a biomethane. The strainer assembly further includes a mixture driving member (53) positioned in the strainer body (47) adjacent the drain opening (51), the mixture driving member having a driving surface configured to receive the liquid passing through the filter member (60). The driving surface engages the filter member such that solid particles are driven from a surface of the filter member when the driving member is activated. A method of continuously producing a biogas and servicing a strainer assembly for a hydrolysis reactor are disclosed.

1. A fermentation system for production of biogas from solid organic material, said system comprising:
a first fermentation reactor configured to produce a first biogas including:
a vessel for housing a feed mixture having liquid and solid particles, the vessel containing an outlet port;a strainer assembly at the outlet port for filtering processed feed mixture from the vessel, the strainer assembly including:
a strainer body having an inlet end fluidly connected to the vessel, service end, and drain opening intermediate the inlet end and service end;a mixture driving member positioned in the strainer body adjacent the drain opening, the mixture driving member having a driving surface configured to drive solid particles in the strainer body towards the inlet end and an upstream end configured to extend beyond the inlet end into the vessel;a filter member positioned in the drain opening configured to allow liquid effluent to pass therethrough and retain desired solid particles in the strainer body; anda drain pipe configured to receive the liquid passing through the filter member; and a second fermentation reactor in fluid communication with the first reactor, the second reactor configured to produce a second biogas, wherein the driving surface engages the filter member such that solid particles are driven from a surface of the filter member when the driving member is activated.
