NOVELTY - Cracking of kitchen microwave pyrolysis residue taken tar involves dehydrating kitchen garbage; drying at 90 degrees C for 5 hours until moisture content is not greater than 5%; subjecting kitchen waste residue to microwave cracking at 500 degrees C; uniformly mixing 5-15% kitchen garbage in microwave cracking reactor; introducing nitrogen for 20 minutes; reacting under anaerobic condition; condensing volatile component product; respectively collecting condensed product and non-condensed gas product; heating kitchen garbage at 500 degrees C to liquefy; and cracking for 5 minutes.    USE - Cracking of kitchen microwave pyrolysis residue taken tar.    ADVANTAGE - The method does not require kitchen waste crushing and use of microwave absorbent, is easy to operate, provides good kitchen waste reduction effect, produces recyclable solid residues and non-condensable gases, and does not produce secondary pollution.    DETAILED DESCRIPTION - Cracking of kitchen microwave pyrolysis residue taken tar comprises dehydrating kitchen garbage; drying at 90 degrees C for 5 hours until moisture content is not greater than 5%; subjecting kitchen waste residue to microwave cracking at 500 degrees C; uniformly mixing 5-15% kitchen garbage in microwave cracking reactor; putting into microwave cracking furnace; introducing nitrogen gas for 20 minutes; reacting under anaerobic condition; feeding volatile component product through first-stage condensing apparatus; collecting condensed product in collecting bottle; collecting non-condensing gas product in collecting bag; heating kitchen garbage at 500 degrees C to liquefy; cracking for 5 minutes; dividing collected liquid in bottle into two layers consisting of upper tar layer and lower weak alkali layer; and separating upper tar layer in storage bottle.    DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a process for cracking kitchen microwave pyrolysis residue taken tar (Drawing includes non-English language text).
