With the rapid development of economy and the improvement of the living standard of substances, a 'garbage surrounding city' is a realistic dilemma faced by most domestic cities, and various modes exist for garbage disposal, mainly including sanitary landfill, biological treatment, incineration power generation and the like. The garbage incineration treatment is to treat the household garbage by utilizing high-temperature oxidation, namely, the household garbage is burnt at high temperature, so that the combustible waste in the household garbage is converted into carbon dioxide, water and the like, and the incinerated ash and slag are only less than 20% of the original volume of the household garbage, thereby greatly reducing the solid waste amount and eliminating various pathogens. However, due to the fact that the components of the household garbage are complex, slagging can occur in the burning process, after the fuel is slagging, the pyrolysis reaction of oxygen and the fuel can be hindered, the burning treatment capacity is reduced, and harmful substances are not thoroughly pyrolyzed. Therefore, how to solve the problem of slag bonding in the incineration process of household garbage in an incinerator is a research hot spot.
Disclosure of Invention
In order to solve the problems, the utility model provides the household garbage incinerator with the combined grate, which adopts the combined grate with the lifting and rotating functions, so that the slag breaking effect can be realized, meanwhile, a burning fire layer on the grate burns from bottom to top, and the burnt fuel enters the grate from the upper part to form flashback, so that various volatile and gasified substances can be burnt to the greatest extent, and the subsequent flue gas treatment pressure is reduced.
In order to achieve the technical purpose, the utility model adopts the following technical scheme:
the utility model provides a household garbage incinerator with a combined grate, which comprises a furnace body, wherein the furnace body comprises an incineration cavity and a secondary heating cavity, and the incineration cavity is communicated with the secondary heating cavity;
the incineration cavity is sequentially provided with a feed inlet, a hearth sealing door, a combustion device, a combined fire grate and an burnout fire grate from top to bottom;
the combined fire grate consists of at least five groups of lifting fire grates and rotating fire grates which are horizontally and parallelly arranged; the rotary grate comprises a rotary rod and a plurality of rotary blades on the rotary rod; the rotary rods of the rotary fire grates sequentially penetrate through the through holes in each group of the lifting fire grates; the rotary blades of the rotary fire grate are arranged between two adjacent lifting fire grates.
The utility model has the beneficial effects that:
the utility model adopts the lifting and rotating combined fire grate, can realize the slag breaking effect, simultaneously, the burning fire layer on the fire grate burns from bottom to top, the burnt fuel enters the fire grate from the upper part to form backfire, various volatile and gasified substances can be burnt to the maximum extent, and the subsequent flue gas treatment pressure is reduced. Furthermore, because the household garbage has complex components and more harmful substances, the harmful substances generated in the incineration process can be exhausted only after being incinerated at a high temperature of above 850 ℃ for a certain time, and the phenomenon that the temperature in an independent incineration cavity is less than 850 ℃ and the combustion is insufficient can be avoided by designing the secondary heating cavity.
