Abstract

The invention discloses an MSW (Municipal Solid Waste) incineration method, and relates to the field of an environmental protection technology. The method comprises three processing steps of garbage preprocessing, mixing and incinerating. According to the method provided by the invention, the garbage is crushed to completely incinerate the garbage in a boiler before the incineration, coal and mountain flour are mixed with the incinerating garage to fully burn a fuel in the boiler, therefore the stability of the circulating ash can be improved, the service life of the boiler can be prolonged, and the garbage incineration efficiency can be further improved by precisely controlling combustion parameters; furthermore, the unnecessary electric energy waste can be saved, and the environmental protection property is good.

Description

A kind of burning city domestic garbage method
Technical field
The present invention relates to environmental technology field, be specifically related to a kind of burning city domestic garbage method.
Background technology
Along with the high speed of China's economy finds, living standards of the people rapidly improve, and the output of house refuse grows with each passing day, and the environmental problem brought thus is also day by day serious.
In prior art, the CFBB of burning domestic garbage, by carrying out fuel to house refuse and fuel mix, again the high temperature of waste incineration is used, reach protection of the environment, the object of the utilization of resources, but consumer waste incineration method of the prior art, owing to reasonably not controlling the parameter in incineration process of domestic garbage and fuel, there is larger fluctuation in the generation that there is the high temperature dust produced in circulating ash and incineration process of domestic garbage, larger adverse effect is created to the thermal efficiency of boiler, and rubbish burning last as also do not carry out pulverization process, cause firing efficiency lower.
Summary of the invention
It is effective that problem to be solved by this invention is to provide a kind of burning, the burning city domestic garbage method of energy-conserving and environment-protective.
To achieve these goals, the technical scheme that the present invention takes for: a kind of burning city domestic garbage method provided, comprises the steps:
(1) rubbish pretreatment: chosen by the rubbish that can not burn in rubbish and obtain burning away the refuse, then can burn away the refuse to send in pulverizer and carry out pulverization process;
(2) mix: by coal, stone flour and can burn away the refuse in stirrer for mixing;
(3) burn: burn in mixed feeding boiler of burning away the refuse, control incineration temperature is 1200-1300 DEG C.
Preferably, in described step (3), boiler air compartment blast controls at 9000-10000Pa.
Preferably, the incorporation time in described step (2) is 1-2h.
Adopt technical scheme of the present invention, before burning, pulverization process is carried out to rubbish, make rubbish in the boiler can sufficient combustion, by mixing coal, stone flour and can burning away the refuse, fuel is sufficient combustion in the boiler, improve the stability of circulating ash, extend the service life of boiler, and by accurate control combustion parameter, incineration firing efficiency is improved further, and saved unnecessary waste of energy, the feature of environmental protection is good.
Detailed description of the invention
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the present invention further.
embodiment 1:
(1) rubbish pretreatment: chosen by the rubbish that can not burn in rubbish and obtain burning away the refuse, then can burn away the refuse to send in pulverizer and carry out pulverization process;
(2) mix: by coal, stone flour and can burn away the refuse in stirrer for mixing, described incorporation time is 1.2h;
(3) burn: burn in mixed feeding boiler of burning away the refuse, controlling incineration temperature is 1210 DEG C, and described boiler air compartment blast controls at 9100Pa.
Based on above-mentioned, in the present invention, before burning, pulverization process is carried out to rubbish, make rubbish in the boiler can sufficient combustion, by mixing coal, stone flour and can burning away the refuse, fuel is sufficient combustion in the boiler, improves the stability of circulating ash, extends the service life of boiler, and by accurate control combustion parameter, incineration firing efficiency is improved further, and has saved unnecessary waste of energy, and the feature of environmental protection is good.
Obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.

Claims (3)
