Household garbage incineration treatment equipment

Abstract

The invention discloses household garbage incineration treatment equipment which comprises a hearth, fire grates, a power generation device, a hopper and an air blower. The fire grates comprise the fixed fire grate and the movable fire grate, the power generation device comprises an aluminum smoke pipe, a water tower, a steam turbine and a power generator, a material pipe is fixedly connected to the bottom of the hopper, a heat exchange bin is fixedly connected to the material pipe, a cover bin is fixedly connected to the outside of the heat exchange bin, and a heat exchange pipe is fixedly connected into the cover bin. The equipment further comprises a waste heat recycling bin. Household garbage is conveyed to the fire grates in the hearth through a hopper and a material pipe to be combusted, steam is generated by energy generated during combustion, then power is generated through the power generation device, and external fresh air is conveyed into the hearth through the air blower to support combustion; and by adding pulverized coal, garbage combustion is more sufficient, garbage can be dried and fresh air can be preheated through the heat exchange bin, ash residues obtained after combustion can be smashed through a smashing roller, and waste heat can be further recycled through the waste heat recycling bin.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to domestic garbage incineration treatment equipment. Background technique [0002] Household garbage refers to the solid waste generated by people in their daily life or in the activities that provide services for daily life. The garbage and waste produced also increased rapidly, and domestic garbage occupied land, polluted the environment, and affected people's health. The large increase in urban domestic garbage made garbage disposal more and more difficult. Environmental pollution and other issues have gradually aroused widespread concern from all walks of life. [0003] Power generation by incinerating domestic waste is one of the main means of waste disposal. It can not only process waste, but also generate electricity for people to use. [0004] But the existing waste incineration treatment equipment also has the following problems: [0005] One: In the process o...

AI Technical Summary

Problems solved by technology

[0005] One: In the process of incineration, it only relies on the combustibles in the domestic waste for combustion, which will lead to low incineration efficiency and incomplete incineration, and there is no simultaneous mixing of appropriate amount of coal powder in the process of waste incineration;

[0006] Its two: the fire grate in its incineration hearth is generally flat and fixed, causing the area of ​​incineration to be small and the ash after incineration, etc. cannot be discharged smoothly in time;

[0007] Third: the ash after incineration is easy to agglomerate, resulting in poor discharge of ash, and the ash after incineration can generally be reused, and the agglomerated ash makes secondary use inconvenient;

[0008] Fourth: During the process of garbage incineration, domestic garbage is directly transported to the incineration furnace, and there is no drying operation for the garbage before incineration, which makes incineration inconvenient;

[0009] Fifth: In the process of incineration, the fresh air from the outside is generally delivered to the incineration furnace by a blower. The oxygen in the fresh air plays a combustion-supporting function, and the temperature of the fresh air is low. When the fresh air with a low temperature is input into the furnace, it will Insufficient combustion of waste;

[0010] Sixth: The waste heat in the waste incineration process cannot be reliably utilized
