Description
Technical field
The invention belongs to technical field of waste treatment, more particularly to a kind of catalyst for waste incineration.
Background technology
Currently, conventional garbage burning facility is all to need to participate in burning with the oxygen in air when burning away the refuse, therefore
It is unlikely to be a closed furnace body, even if having installed emission-control equipment additional, exhaust gas is generated in Refuse Incineration Process and more or less all can
It being leaked in outside air, the dioxin in exhaust gas is the pollution sources that the maximum that waste incineration generates is also most serious, as long as
It burns, this cannot be avoided, and most of still more existing garbage incinerating system is all directly to be discharged into the exhaust gas of generation
In air, cause greatly to pollute to environment, and some also needs to external power supply in garbage incinerating system, energy consumption is larger, pole
Not environmentally.
Invention content
For solve the above-mentioned problems in the prior art, the present invention provides it is a kind of make closed incinerator without
With in air oxygen and without can be allowed under external power supply burn intracavitary rubbish burn away, effectively prevent waste incineration
Process waste gas is discharged into external environment, and can effectively be purified to the flue gas and waste water of generation, and energy conservation and environmental protection can also be significantly
Improve the catalyst of waste incineration rate and garbage treatment efficiency.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：
A kind of catalyst for waste incineration is by that can decompose the middle hydrone that waits burning away the refuse, generate waste incineration
The component A of required oxygen, the B component that the waste water that can be generated to waste incineration carries out disinfection, the flue gas that can be generated with waste incineration
In the dioxin harmful organic substance that contains reacted, be converted to the C components of harmless inorganic matter and mixed；And mixing one
The component A that rises, between B component and C components without chemical reaction, between ratio be 90~96：2~5：2~5.
Further, the component A is peroxide or potassium permanganate.
Further, the component A is 2Na2CO3·3H2O2Or H2O2Or Na2O2Or K2O2Or CaO2。
Further, the component A, B component and C components are CaO respectively22、NaOH、Na3SO4, and CaO2：NaOH：
Na3SO4It is 94：3：3.
The beneficial effects of the invention are as follows：
The present invention through the above technical solutions, can make closed incinerator without in air oxygen and without outer
Connecing can allow the rubbish for burning intracavitary to burn away under power supply, effectively prevent Refuse Incineration Process exhaust gas and be discharged into external environment
In, and the flue gas and waste water of generation can effectively be purified, energy conservation and environmental protection is also greatly improved at waste incineration rate and rubbish
Manage efficiency.
Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, by the following examples, to the present invention
It is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, is not used to limit
The fixed present invention.
Described in the embodiment of the present invention be used for waste incineration catalyst, be by can decompose the middle hydrone that waits burning away the refuse,
The component A of oxygen needed for waste incineration is generated, the B component that the waste water that can be generated to waste incineration carries out disinfection can be burnt with rubbish
Burn the dioxin harmful organic substance that contains in the flue gas generated reacted, be converted to harmless inorganic matter the mixing of C components and
At；And without chemical reaction between component A, B component and the C components being mixed, between ratio be 90~96：2~5：2
~5.Wherein, the component A can be peroxide (such as CaO2Or 2Na2CO3·3H2O2Or H2O2Or Na2O2Or K2O2) or Gao Meng
Sour potassium, the B component can be NaOH, and the C components can be Na3SO4；Such as：The component A, B component and C components difference
It is CaO2、NaOH、Na3SO4, and CaO2、NaOH、Na3SO4Between best weight ratio be 94：3：3 (certain CaO2：NaOH：
Na3SO4Can also be 90：5：5 or 96：2：2).
After lighting rubbish in closed incinerator, by incinerator convey catalyst of the present invention (such as：It will urge
Agent is packed into the catalyzing tank for burning chamber connection of delivery outlet and incinerator, and incineration firing process catalyzing tank is urged to chamber conveying is burned
Agent) i.e. decomposable asymmetric choice net wait burning away the refuse middle hydrone, generate oxygen needed for waste incineration (such as：Component A is CaO2, 2CaO2+
2H2O=2Ca (OH)2+O2), so that the garbage energy in burning chamber 11 is burnt away, while to containing in flue gas caused by incineration firing
Some dioxins are harmful to organic chloride and the harmless inorganic matter such as are reacted, are converted to sodium chloride, sodium carbonate, hydrogen (two dislike
99%) English resolution ratio is more than, and carry out disinfection to the waste water of generation.
In this way, through the invention the catalyst can make closed incinerator without in air oxygen and be not necessarily to
The rubbish for burning intracavitary can be allowed to burn away under external power supply, Refuse Incineration Process exhaust gas is effectively prevented and be discharged into extraneous ring
In border, and the flue gas and waste water of generation can effectively be purified, energy conservation and environmental protection, also be greatly improved incinerator (burning chamber)
Internal core incineration temperature (about 300 degree, stove table temperature be 60 degree), waste incineration rate significantly improve (minimizing is obvious,
Clinker ashes are 50 kilograms after 1 ton of waste incineration, and decrement reaches 95%, and rubbish is thrown into stove and handled at any time without stacking at any time,
Transportation cost, human cost and time cost are reduced from rubbish source of generation, freight volume is reduced to 12 days freight volumes daily originally,
Clinker ashes can be used as construction material additive), garbage treatment efficiency is high (a kindling day handles 600 kilograms of rubbish).
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also considered as
Protection scope of the present invention.
