Fire grate and pyrolysis combined waste incineration equipment

Abstract

The invention provides fire grate and pyrolysis combined waste incineration equipment. With a pyrolyzing furnace as a major, a grate furnace is installed at the feeding end of the pyrolyzing furnace obliquely; the feeding end of the grate furnace is connected with a waste guide bin, an inlet of the waste guide bin is upward, and a gantry crane claw is arranged above the inlet of the waste guide bin; a slag outlet of the pyrolyzing furnace is connected with an automatic slag discharging machine; a storage tank is arranged below the automatic slag discharging machine; a secondary combustor is installed on the upper left portion of the grate furnace; and the upper portion of the pyrolyzing furnace is provided with a circulating pipeline, high-temperature flue gas enters a buring section of the pyrolyzing furnace through the heat circulating pipeline. By means of the equipment, combustibles are greatly reduced, and toxic and harmful ingredients in flue gas are thoroughly burnt. Purification energy consumption of flue gas of the rear end is reduced, the whole equipment is in the same space but different sections, heat is utilized to the greatest extent, and resource utilization is achieved.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a combined fire grate and pyrolysis waste incineration equipment. Background technique [0002] The pyrolysis incinerator is one of the most effective incinerators for the incineration of domestic and medical waste. The content of heavy metals in the ash produced after incineration is the lowest. Because the combustion layer and drying layer of the pyrolysis furnace are located in the same section On the other hand, the coaxing effect is not good and the drying time is too long, and the high-temperature flue gas in the waste incineration process is not recycled, which affects the amount of incineration; since most of the heat energy generated by incineration is used for waste drying, most of the heat energy cannot enter the secondary Combustion chamber, resulting in an increase in the combustion aid required by the second combustion chamber, increasing energy consumption. ...
