Vertically-arranged garbage incinerator

Abstract

The invention relates to a vertically-arranged garbage incinerator. The vertically-arranged garbage incinerator comprises an air-blast slag discharging mechanism, an incineration hearth, a waste heatexchanger and a flue gas treatment system; the air-blast slag discharging mechanism is arranged at the bottom of the incineration hearth, the incineration hearth is cylindrical, the top of the incineration hearth is provided with a heat accumulator, the waste heat exchanger is arranged above the heat accumulator, and an air outlet of the heat accumulator communicates with a heat medium inlet of the waste heat exchanger; and the flue gas treatment system is arranged above the waste heat exchanger, and a heat medium outlet of the waste heat exchanger is connected to the flue gas treatment system. According to the garbage incinerator, the height space is fully utilized, the occupied area of equipment is greatly reduced, efficient combustion, energy conservation and environmental protection are achieved, and the garbage incinerator is beneficial to reducing the equipment cost and the using cost.

Description

technical field [0001] The invention belongs to the technical field of incinerators, in particular to a vertically arranged garbage incinerator. Background technique [0002] Most of the existing waste incinerators use horizontal grate furnaces, which mainly have the following disadvantages: [0003] First, the horizontal grate furnace occupies a large area, resulting in a low utilization rate of the equipment, which is not conducive to saving costs; [0004] Second, the flue gas generated by the combustion of the horizontal grate furnace needs to be extracted by the exhaust equipment, the resistance to be overcome is large, and the energy consumption is large, which is not conducive to reducing the cost; [0005] Third, horizontal grate furnaces generally need to build high chimneys to discharge the treated flue gas generated by combustion, which not only increases the construction cost, but also is not beautiful, which is easy to cause the rejection of the public; [000...

AI Technical Summary

Problems solved by technology

[0003] First, the horizontal grate furnace occupies a large area, resulting in a low utilization rate of the equipment, which is not conducive to saving costs;

[0004] Second, the flue gas generated by the combustion of the horizontal grate furnace needs to be extracted by the exhaust equipment, the resistance to be overcome is large, and the energy consumption is large, which is not conducive to reducing the cost;

[0005] Third, horizontal grate furnaces generally need to build high chimneys to discharge the treated flue gas generated by combustion, which not only increases the construction cost, but also is not beautiful, which is easy to cause the rejection of the public;

[0006] Fourth, the hearth of the horizontal grate furnace is short (0.8m ~ 1.0m), and it is impossible to realize the self-heating of the cold air blast. Generally, the flue gas generated by the combustion is extracted to exchange heat with the cold air, and the heat exchange is used to The final hot air blasts the furnace, the heat exchange efficiency is low, and the air temperature is low, which is not conducive to improving the combustion intensity, and increases the equipment cost
