Embodiment 1

[0026] like figure 1 As shown, a waste incineration device with a wide range of calorific values ​​includes an incineration furnace and a number of rotating airfoil arch mechanisms arranged in parallel. The rear arch 6, the garbage inlet 7, the fire grate 8, the slagging outlet 10, the left and right side walls 11, and the vertical flue 4, the garbage inlet 7 is set at the front end of the fire grate 8, and the slagging outlet 10 is set at the furnace At the end of row 8, the incinerator hearth outlet 5 is located between the rear arch 6 and the highest point of the front arch, and the vertical flue 4 is connected to the incinerator hearth outlet 5. A secondary air component 3 for providing secondary air is arranged on the vertical flue 4 .

[0027] like figure 2 As shown, the rotating airfoil arch mechanism package is arranged on the rotating airfoil arch 2, transmission shaft 9, bearing 13, sealing component, shaft coupling 15 and motor 16 in the incinerator chamber, and ...

Embodiment 2

[0032] A garbage incineration method for a garbage incinerator with a wide range of heat values, comprising the steps of:

[0033] The garbage enters the grate 8 through the garbage inlet 7, and the primary wind is blown in from the bottom of the grate 8. Under the movement of the grate 8, the garbage undergoes four processes of preheating and drying, pyrolysis, fixed carbon combustion and burnout. The flue gas is discharged from the outlet 5 of the incineration furnace and the vertical flue 4, and the ash is discharged from the slag outlet 10 of the incineration furnace;

[0034] When the calorific value of the garbage is low, the rotating airfoil arch 2 can be turned to a position parallel to the rear arch 6. At this time, the rotating airfoil arch 2 can radiate heat to the garbage material layer, increase the temperature in the furnace, and make the garbage burning more stable , and at the same time force the high-temperature flue gas to wash away the garbage and accelerate...

Abstract

The invention discloses a waste incineration device with a wide calorific value application range. The waste incineration device comprises an incineration hearth and a rotary wing type arch mechanism, wherein the rotary wing type arch mechanism comprises a rotary wing type arch, a transmission shaft, a bearing, a sealing part, a shaft coupler and a motor which are arranged in the incineration hearth; one end of the transmission shaft is fixed with the rotary wing type arch; the other end of the transmission shaft passes through a furnace wall and is in driving connection with the motor through the shaft coupler; the bearing is arranged between the transmission shaft and the furnace wall; the sealing part is arranged in a seam between the transmission shaft and the furnace wall; and the rotary wing type arch rotates by a proper angle under driving of the motor. The invention further discloses a waste incineration device with a wide calorific value application range. According to the waste incineration device and method disclosed by the invention, the design of the rotary wing type arch is adopted, a proper angle is rotated, radiation heat during waste incineration can be adjusted, temperature fields in the hearth are kept stable, and waste is guaranteed to stably combust; and flue gas disturbance in the hearth and retention time, in the hearth, of the flue gas also can be increased, and a waste calorific value is wide in application range, so that the waste incineration device and method are worthy of being popularized in the waste incineration field.

Description

technical field [0001] The invention relates to a garbage incineration method and device, in particular to a garbage incineration device and method with a wide range of calorific values. Background technique [0002] With the development of the economy, people's living standards are getting higher and higher. At the same time, the garbage generated in people's daily life is also increasing. How to properly dispose of garbage is getting more and more people's attention. At present, there are three main methods of waste disposal: sanitary landfill, incineration and composting. However, sanitary landfill and composting require a large amount of land, and these two methods are not suitable for use in large cities. Incineration treatment has the advantages of reduction, harmlessness and resource utilization, so it is welcomed by cities. [0003] Domestic waste has the characteristics of high water content and high ash content, and its calorific value is generally low. When it ...
