Description

technical field [0001] The invention relates to an incineration treatment device for garbage, in particular to a harmless incineration treatment device for domestic garbage, which belongs to the technical field of domestic garbage treatment equipment. Background technique [0002] In the technical field of environmental pollution control and garbage disposal, the most practical and reliable method is to incinerate first and then landfill in the face of huge domestic garbage pollution sources, because the volume of garbage after incineration is only 1 / 5 of the original, and the weight is the original 1 / 15 of that can effectively reduce capacity. The premise of incinerating waste is to do a good job in waste reduction and waste classification. [0003] Incineration of domestic waste, and at the same time, the flue gas after waste incineration is effectively conditioned and discharged to high altitudes, that is to say, it is one of the important means of environmental governan...

Problems solved by technology

[0004] At present, the mainstream garbage harmless treatment device scheme is: including incinerator, flue gas control gate, flue gas turbulent flow channel, water mist dedusting pool, flue gas surrounding channel, induced draft fan, flue exhaust channel, water storage tank, etc. The feeding port is set on the top of the furnace, and the upper and lower flues are chambers surrounding the outer wall of the furnace. According to the characteristics of the physical components of its patented technology, after opening the slag cleaning door, two equal-velocity but not-isothermal parallel flow fields are in contact with each other in the combustion chamber. , the furnace temperature will quickly drop from a higher value to a lower value, and it is difficult to solve the problem of steady-state temperature in the center of the furnace, and it is impossible to promote the full combustion of garbage in the combustion chamber. In addition, the flue gas and the high-pressure spray water are in contact with each other, and the treatment method is not compatible with the physical and chemical characteristics, and the effect of dust removal and desulfurization is not obvious.

[0005] The patented technology of China Patent No. 200810024382.6 discloses a patented technology of "garbage incineration treatment device and its treatment method". Harmless treatment of garbage, the flue gas treatment system consists of flow rate control components, turbulent flue gas duct, high-pressure spray dust removal tank, activated carbon adsorption chamber, induced draft fan and flue gas drying chamber, the furnace of this patent technology, in The oxygen-increasing tube installed in the center of the furnace can only increase oxygen instantaneously. Because the normal-temperature air sent into the furnace lacks heat production due to the high conduction velocity, a large amount of coking will occur in the center of the furnace during the combustion process. Garbage The air required for incineration cannot be supplied normally, which affects the quality of incineration and the increase and stability of the furnace center temperature. In addition, the high-pressure spray dust removal of the flue gas treatment system also adopts the homeopathic spray method, and the flue gas that receives high-pressure spray The temperature is as high as above 800°C, and the expansion coefficient of the gas generated in contact with high-pressure spray water is as high as three times. The effect of dust removal and desulfurization can not meet the ideal conditions. The intercepting component of 0.5μm particulate matter, that is to say, it is equipped with the necessary material basis for further conditioning of the discharged flue gas

[0006] Based on the analysis of the above two patented technologies, in addition to the above-mentioned unreasonable measures, there is also the effective use of heat energy emitted by the furnace body and high-temperature flue gas. The phenomenon of complete combustion and incomplete combustion of garbage caused by insufficient air and excess air is present throughout the operation. In the process, it is generated in turn, and the thermal balance of the combustion chamber cannot be guaranteed, so that harmful gases are easily generated, etc.

Carefully analyzing the entire processing system, there are still technical flaws, not very perfect
