Garbage burning equipment with forward-pushing three-section type cooling high-pressure loss fire grate and method for burning garbage by using garbage burning equipment

Abstract

The invention relates to garbage burning equipment and particularly relates to a three-section type fire grate and a burning furnace with the same, i.e., garbage burning equipment with a forward-pushing three-section type cooling high-pressure loss fire grate and a method for burning garbage by using the garbage burning equipment. The garbage burning equipment comprises a drying section, a burning section and a burnout section; the forward-pushing fire grate comprises a sliding fire grate, a fixed fire grate and charging fire grates; the fire grate is composed of the sliding fire grate driven by a sliding fire grate beam, the fixed fire grate sliding on a supporting frame and fixed on the fixed fire grate beam and the charging fire grates arranged at tail ends of all the sections of fire grates; height differences exist among all the fire grate sections and among all regions; and the burnout fire grate is installed horizontally. With the adoption of the equipment, 5-6 months are taken as one repair cycle; in addition, the operating and maintaining costs are also reduced by about 80% than the initial cost, and the property is improved by 20% under the same cost.

Description

Technical field [0001] The invention relates to a garbage incineration equipment, in particular to a three-stage grate and an incinerator. Background technique [0002] In the 21st century, my country's environmental protection and heating industry has made rapid progress. The single-seat waste incinerator reaches 750~1000 square meters, and the single-unit capacity of the incinerator is increasing. In the past 10 years, my country's strata-burning large-capacity waste incinerators have almost all adopted beam moving grate. The advantages of this grate are stable operation and low maintenance rate. Because the use temperature of the existing grate block itself should not be too high, it is a better cooling equipment, so the equipment is moved in rows, because there can be gaps between rows, and then the furnace can be effectively cooled through ventilation. The disadvantage is that the slag leakage rate is relatively unsatisfactory, the operation power consumption is high, the ...

Problems solved by technology

Because the operating temperature of the existing grate block itself should not be too high, in order to better cool the equipment, the equipment is moved in a row, because there can be a gap between the rows, and then the furnace can be effectively cooled by ventilation The disadvantage is that the slag leakage rate is relatively unsatisfactory, the power consumption of operation is high, the dust concentration generated after combustion is large, and the particle size is small, and the maintenance cycle of the existing three-stage grate is 4 months, which takes a long time. The operation and maintenance cost can not always reach the ideal goal. Another disadvantage is that the garbage does not roll over on the grate, and is ignited from above by the high temperature in the furnace (single-sided ignition), so the calorific value, volatile matter, There are high requirements for coking properties; when the waste value deviates from the design value, the output and operating efficiency of the incinerator will drop significantly
