Background technology

Along with Chinese economic development, problems such as municipal sewage treatment, refuse treatment, sulfur dioxide emissions, Dioxins poisonous substance have had a strong impact on the Sustainable development of Urbanization in China and China.

At present, the filtrate of known raw water filtration device mainly contains two kinds, and a kind of is non-adsorptivity, i.e. quartz sand, pottery, plastics etc., and another kind has adsorption function, as carbon leaching material.Yet, filtering material for above two kinds of former water all is to use under the situation relatively preferably in the water quality of former water, and the amount of dirt is big inadequately in the filtering water, and the cycle of operation is shorter relatively, therefore, the rejection rate for some undesirable substances such as the pathogenic bacterium in the water, organism, heavy metals is lower.And conventional domestic sewage processing system, the cost of water treatment height, water quality inferiority, and its sediment contains a large amount of pathogenic bacterium and toxic substance, makes mud cause secondary pollution.

And because the present handled mode of domestic refuse is to fill out and modes such as waste incineration and generating electricity are handled by burying, rubbish bury occupy with a large amount of soils in addition its existence of oozing drop liquid underground water and surrounding environment have been constituted severe contamination, and waste incineration and generating electricity can produce the flying dust of a large amount of Dioxins poisonous substances, environment is caused serious secondary pollution, known garbage burning boiler can produce a large amount of flying dusts that contains the Dioxins poisonous substance, and the Dioxins poisonous substance is difficult to decompose under normal temperature condition, and this poisonous substance has seriously formed second environmental pollution.

The condition that produces Dioxins in waste incineration is: (1) combustion instability.(2) combustion temperature in hearth is inhomogeneous.(3) temperature of combustion＜850 ℃.(4) metal catalytic.

Though the fluidized bed garbage combustion boiler is the superior burning mode of a kind of over-all properties, especially be fit to the characteristics that China's rubbish is low with the seasonal variation calorific value, composition is complicated.Fluidized bed refuse incinerator adopts quartz sand as thermal barrier, and heat storage capacity is big, and combustion stability is good, and combustion reaction temperature is even.The fluidized-bed combustion temperature has effectively been contained the existence of Dioxins in ashes between 850 ℃-950 ℃.Yet, but can not stop the later stage of Dioxins in boiler systems synthetic.In addition, the rubbish water content is big, and the combustion power generation economic benefit is not high.The core of consumer waste incineration treatment technology is the rational proportion of fuel and the control of incendiary control rationally and secondary pollution.Domestic refuse is because its water content is big, and directly throwing being thrown and burning in the boiler and will the stable burning and the raising furnace temperature of boiler be had a negative impact.Influence boiler stable burning owing to domestic refuse is moisture, temperature is subjected to the influences of a large amount of heat absorptions of water evaporation in addition, and furnace temperature reduces, and boiler operatiopn will be moved in the temperature range that can produce a large amount of Dioxins poisonous substances.And increased the vapour content of flue gas greatly, because the water vapor heat content is big, not only absorbed the heat energy that can do work in a large number, the boiler temperature that makes is elevated to the decomposable temperature of Dioxins and makes flue-gas temperature be reduced to the difficulty of Dioxins resynthesis temperature rapidly all very big.And the reduction of the high moisture and temperature of flue gas will make HCl gas that the harm of garbage incinerating system is increased, and can cause the high temperature corrosion damage of furnace heating surface and the low temperature corrosion of back-end surfaces.This safe operation to boiler will produce greatly and threaten.

Fuel is most of to be coal because China's heat power station uses, and the coal sulfur-bearing of China is higher, and known power industry is to cause SO ₂The main industries of pollution and acid rain, SO ₂A large amount of dischargings cause the atmospheric pollution of Chinese city very serious.SO ₂Discharging has caused serious acid rain to pollute and ecological damage, thereby its environmental influence has received very big concern.The portion report " clear water blue sky Zhao is looked forward to the Chinese environmental of 21 century " of the World Bank has estimated that Chinese topsoil and water pollute the influence to environment.According to the estimation of willingness to pay value method, China's loss of (1995) big G﹠W pollution at present accounts for 8% of GDP.If adopt the human capital technique of estimation, its loss is equivalent to 3.5% of GDP.Along with SO ₂The increase of quantity discharged, the loss cost that is caused increases sharply.According to relevant research, nineteen ninety-five, China was because acid rain and SO ₂It is more than 1,100 hundred million yuan that pollution causes the financial loss of aspects such as farm crop, forest and HUMAN HEALTH, and 2.0% of approaching gross national product then becomes the important factor that restricts China's economy and social development.Therefore, to SO ₂The control of discharging is imperative.

At present, the SO 2 from fume system of removing generally is divided into (a) dry washing system and (b) wet scrubbing system, and in the dry washing system, the solution of reagent or slurries are sprayed in hot flue gas, its moisture is evaporated, collects the quite dried byproduct that helps handling then.In the wet scrubbing system, make reagent for example the solution or the slurries of alkali reagent or alkaline earth reagent contact with gas, collect and handle wet mud then.Yet, adopt conventional sulfur removal technology to make boiler efficiency reduce, cost of electricity-generating significantly improves, and the solid waste quantity discharged increases.

A large amount of good water sources has been consumed in known thermal power generation, utilize the former water desalination technology of hot gas as thermal source, mostly be utilize the pump circulation, realize by evaporation or flash distillation, but because its equipment scaling is serious, be difficult to long-term trouble free reliability service, by adding modes such as acid water is carried out pre-treatment mostly, therefore, the cost height, dangerous, comparatively serious to the corrosion of equipment.Because of its circulation needs water pump, big energy-consuming is difficult to realize the scale operation of fresh water.Limit the application of hot gas thermal source aspect former water desalination greatly, be difficult to extensively carry out popularization.

At present, known cooling tower is cold water formula and two kinds of principal modes of air-cooled type.These two kinds of cooling towers have natural draft cooling tower and mechanical-draft cooling tower again.Because water cooling tower mainly is subjected to the influence of air ' s wet bulb temperature, be to dispel the heat, so its consumption to water is very big by evaporation of water and conduction.And atmospheric cooling tower is to utilize conduction that air is absorbed heat to realize heat radiation mainly being subjected to the influence of air dry-bulb temperature.Because air dry-bulb temperature is higher, specific heat is little, and heat absorption capacity is limited, and cooling efficiency is low, therefore, needs air-cooler that very big surface-area is arranged, and the air-cooler cost height that makes makes its popularization be subjected to restriction serious.Above problem has produced serious challenge to the cleaner production and the Sustainable development of China.
