Garbage combustion furnace high in combustion efficiency

Abstract

The invention discloses a garbage combustion furnace high in combustion efficiency. Household garbage is put into a furnace chamber of the combustion furnace from the top of the combustion furnace, and air is fed into the furnace chamber from the bottom, so that the garbage is combusted from bottom to top, and waste residues are discharged through a residue discharging port in the bottom. Final tail gas of garbage combustion is exhausted from the lower portion of the furnace chamber after being combusted sufficiently, so that the temperature inside the furnace chamber is decreased gradually from bottom to top. According to the garbage combustion equipment which is optimized in design and is high in gas circulation efficiency, the lower portion of a furnace body can be effectively cooled through an annular cooling chamber arranged outside the furnace body; meanwhile, on one hand, the air is preheated after flowing through the periphery of the upper portion of the furnace body and then enters the furnace chamber, so that the situation that cold air enters the furnace chamber, and consequently the temperature in the furnace chamber and the combustion efficiency in the furnace chamber are influenced is avoided; on the other hand, the air enters the furnace chamber uniformly from the bottom of the furnace chamber, so that uniform combustion in the furnace chamber is guaranteed, the air utilization rate is greatly increased, the treatment temperature in the furnace chamber is guaranteed, and the combustion efficiency in the furnace chamber is greatly improved; and furthermore, the tail gas is exhausted after being cooled through the cooling chamber, and accordingly the subsequent tail gas treatment is facilitated.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a garbage incinerator with high combustion efficiency. Background technique [0002] In recent years, with the improvement of people's living standards, the generation of municipal solid waste has increased rapidly, and the stock of waste accumulation over the years has been huge. It is usually disposed of by landfill, causing waste to erode a large amount of land. The incineration method can maximize the effective treatment of domestic waste and occupy the least land resources. However, if the incineration tail gas is discharged directly without treatment, it will cause serious air pollution. In the existing waste treatment technology, pyrolysis and gasification are the main methods. However, due to the poor air permeability of the waste in the furnace, the burning speed is slow, and it is difficult to fully burn, which affects the efficiency of waste treatment. There...
