Innocent treatment device for domestic waste and method

Abstract

The invention discloses an innocent treatment device for domestic waste and a method. The device comprises a bag breaking machine, a shaftless drum screen, a magnetic separator and a shredder, whereinthe shredder is connected to a stock bin of a pyrolysis gasification furnace, the pyrolysis gasification furnace is connected to a high-temperature combustion chamber, the high-temperature combustionchamber is connected to a cooling water tank, the cooling water tank is connected to a settling tank through a draft fan and a connecting pipeline, a thermoelectric generation device is arranged on the connecting pipeline, and the settling tank is connected to a flue gas emission device; and the innocent treatment device for the domestic waste further comprises a control device, and temperature sensors and pressure sensors are arranged at all positions. The invention further comprises a method for conducting innocent treatment on the biochemical waste by adopting the device. According to thedevice and the method, the innocent, reducing and recycling treatment of the domestic waste can be achieved, the power generation utilization is conducted, the finally-effluent flue gas can reach theemission standard, and the problems that an existing waste treatment method is large in environmental pollution, low in resource utilization rate, high in treatment cost and the like are effectively solved.
