Energy saving and environmental protection tumble dryer

Abstract

The invention discloses an energy-saving and environment-friendly rotary drum dryer. The energy-saving and environment-friendly rotary drum dryer comprises a rack, wherein a thermal dehydration part and a constant-temperature dehydration part are rotationally mounted on the rack; a first rotary driving mechanism and a second rotary driving mechanism are mounted on the rack; an upper drum feeding part is mounted at one end of the thermal dehydration part; an upper drum guiding part is mounted at the other end of the thermal dehydration part; a lower drum feeding part is mounted at one end of the constant-temperature dehydration part and positioned below the upper cylinder guiding part; a discharging part is mounted at the other end of the constant-temperature dehydration part; a heat source is part is connected to the upper drum guiding part; a waste-heat utilization part is connected to the upper drum feeding part; and an exhaust collection part is connected to the lower drum feeding part. The energy-saving and environment-friendly rotary drum dryer utilizes renewable biogas as a fuel to heat up air so as to finish dehydration, sterilization, trace carbonization and drying treatment of kitchen waste, and therefore, solves the problems that a conventional kitchen waste disposal method causes much pollution and hazards to the environment, is incomplete in disposal, demands much on equipment and environment, and is high in energy consumption and low in output.

Description
