Description
Technical field
The present invention relates to the high-efficiency low-pollution sludge incineration treatment system of the grate firing of high-temperature and low-oxygen combustion technology, be specifically related to sludge high temperature air incinerating method and device.
Background technology
Mud is the accessory substance that life and trade effluent are handled, this accessory substance is rich in microorganism, pathogen, virus etc., has stronger pollution character, if it is mishandling, can form pollution spread widely, the approach of its pollution has usually: the random stacking of (1) mud will be infiltrated surface soil layer polluted surface water system; (2) do not carry out the mud that hygienization handles and enter the farmland, may directly threaten human food chain; (3) mud distributes stench, or distributes harmful substance in atmosphere, atmosphere is formed pollute.The method of Treatment of Sludge mainly contains: (1) agriculture compost.But contain harmful substances such as a certain amount of heavy metal element and virus, pathogen, parasitic ovum in the mud, impose on the farmland and can produce toxic action to the mankind by the transmission of food chain and biological chain.(2) mud landfill.The mud burying method is simple, and expense is cheap, is a kind of main disposal options at some national landfill therefore, but landfill is occupied a large amount of soils, simultaneously, because mud contains certain noxious material, landfill is improper might be because of the leaching contaminated soil and the underground water of leachate.(3) mud is thrown the sea.Utilize the self-purification capacity of ocean, throw the sea and handle mud and adopted by many countries always, but since this disposal options to marine ecology, environmental sanitation and serious consequence that water pollution caused, this method is restricted gradually.(4) sludge incineration.Because burning process energy consumption height, the required energy of oxidation reaction can not be self-supporting, needs other makeup energy, so the operating cost height.But it is fast with processing speed, minimizing degree height, reusing of energy source, outstanding feature such as it is thorough to sterilize and being celebrated.
Countries in the world all more strict requirement has been proposed in time and the shared space that Treatment of Sludge spent, thereby the sludge incineration technology progressively becomes the mainstream technology of Treatment of Sludge, more and more is subjected to the favor of countries in the world.Burning process is except consumes energy, beyond cost and the running cost height, also can bring harmful substances such as smoke pollution and generation bioxin, at present, developed country is all in the discharge standard of formulating stricter solid incinerator flue gas, and this also will propose higher requirement to the burning of mud.
Sludge incineration is now handled usually with fluidized-bed combustion boiler and kiln, the mud that requires stove is through just handling, go into the stove sludge water content about 80%, need to add a large amount of auxiliary fuels, for UTILIZATION OF VESIDUAL HEAT IN waste heat boiler need be installed in addition, cause system complex, the operating cost height needs government to give double subsidy to Treatment of Sludge with the generating electricity price simultaneously and just can keep.So, the key of sludge incineration treatment process be to develop thermal efficiency height, expensive little, operating cost is low, and the burning process of compliance with environmental protection requirements.
Summary of the invention
