Reactor primarily of feedwell, prehydrolysis reaction chamber, acidication reaction chamber, mechanical manipulator, draining grid, drop liquid collecting tank, recharge pump, recharge pipe, wet-pit, well of slagging tap, PH conditioning agent dispensing port, heating coil composition.
Primary organic solid castoff enters in prehydrolysis reaction chamber from feedwell, and the organic solid castoff in prehydrolysis reaction chamber is grabbed and sent into acidication reaction chamber by mechanical manipulator.Mechanical manipulator can be uniformly mixed the solid waste in prehydrolysis reaction chamber, acidication reaction chamber.Organic solid castoff is converted into dissolved organic matter or tiny organic solid particles by the effect of microorganism in prehydrolysis reaction chamber and acidication reaction chamber, is flowed in drop liquid collecting tank by draining grid with the form of drop liquid.Drop liquid in drop liquid collecting tank recharges hydrolysis acidification reaction indoor by recharging pump and recharging pipe.After having reacted, the solid residue in acidication reaction chamber is delivered to by gripper of manipulator well array of slagging tap and is gone out reactor.
Described prehydrolysis reaction chamber has certain shock absorption, can come doses and back-end processing amount by balancing front-ends.
Establish heat exchange coil to control temperature of reaction in described prehydrolysis reaction chamber and acidication reaction chamber.
Described drop liquid pool is located at the bottom of prehydrolysis reaction chamber and acidication reaction chamber, arranges PH conditioning agent dispensing port to control the pH value reacted.That recharges that the filtrate of drop liquid pool is transported to acidication reaction chamber top by pump recharges pipe, drop liquid is recharged acidication reaction chamber to accelerate the hydrolysis reaction of organic solid castoff.Drop liquid in drop liquid pool is discharged reactor by wet-pit.The drop liquid of discharging reactor is the desirable feedstock that subsequent disposal utilizes.。
The biochemical pretreater of the organic solid castoff that the utility model proposes, without the need to carrying out sorting to material, without the need to configuring pulping equipment, mass transport is simple and reliable, the percolate generated after acidication reaction is easy to be anaerobically digested process, improve the reaction efficiency of anaerobic digestion, significantly save facility investment and working cost.
