Description

Water-cooled garbage incinerator with full combustion

Technical Field

The invention belongs to the technical field of garbage incineration, and particularly relates to a fully-combusted water-cooled garbage incinerator.

Background

At present, the garbage is mostly treated by adopting a burning or landfill mode in the garbage treatment industry. The vertical garbage incinerator used for garbage incineration is easy to leave a lot of residues in the incinerator after being used, and part of residues are adhered to the inside of the furnace chamber and are difficult to remove. When the ash in the conventional garbage incinerator is cleaned, the top cover is required to be opened, cleaning staff drills into the furnace chamber to clean, the work is time-consuming and labor-consuming, and the difficulty is increased for drilling from the furnace top to clean the furnace chamber due to the fact that part of the garbage incinerator is narrow in the furnace chamber. In addition, the traditional garbage incinerator is provided with a slag discharging port at the bottom of the incinerator, and the bottom of the incinerator adopts an inclined design, so that residues obtained after garbage incineration can freely slide and be discharged. However, as the opening is smaller, residues cannot be completely discharged, and more residues are left at the bottom of the furnace; and moreover, the inclined furnace bottom is inconvenient for staff to stand, so that the difficulty of the staff entering the furnace chamber for cleaning is increased. The waste incinerator is usually cooled by water cooling, namely, a cooling water pipe is added into the furnace wall to reduce the temperature in the furnace after incineration. Hot water obtained by the water cooling system is always directly discharged, so that waste is caused.
