Description
Technical field
The present invention relates to a kind of civil heating stove and accessory, specifically a kind of tube-sheet type condensation environment protection warming stove.
Background technology
The traditional civil heating stove now commercially sold, due to low content of technology, is designed with defect, and be fuel with bituminous coal, except the low energy waste seriously of the thermal efficiency, go back severe contamination atmospheric environment, civilian traditional heating stove and so-called smokeless industry boiler cause haze weather primary pollution source.Rural energy waste has caused the attention of the Ministry of Agriculture, and according to Academy of Agricultural Sciences's economy and Institute of Development Studies, doctor Zhu Lizhi is about in energy economy and discharge reduction in rural area one literary composition.The evenly heat efficiency of life in the countryside cooking stove a heatable brick bed is for being only 25%.Far below the standard of national GB/T16154.2005 General coal stove technomania efficiency 60%.Rural area consumption 900,000,000 tons, coal in 2006, account for 1/4th of whole nation coal, pollution index accounts for 1/3rd of the whole nation, and the situation is tense in agriculture energy-saving and emission-reduction.
At present, in fuel consumption field, fire coal occupies sizable proportion, and especially northeast and the Northwest's fire coal consume particularly serious, and main consumption ways is then the Boiler heating in winter.In coal-fired process, the produced pollution is very serious, and the pollutant that in the atmosphere pollution of China, fuel combustion produces accounts for 70% of all contaminants quantity, and therefore fuel combustion is that energy consumption is high, utilization rate is low, the combustion system of low-altitude discharged.The level of pollution in northern China city is higher than Shelter in South China Cities, and winter, sooner or later higher than noon, bituminous coal was a kind of fossil resource, and cigarette sulfur content in coal is high and general higher than summer.In recent years, in society general by sulphur content lower than 0.5 coal-anthracite be called low-sulfur coal.Middle-size and small-size coal-fired boiler is industrial heating and household heating mainly.Especially north of china in winter peasant warms oneself with arcola, and distribution is wide, and layout is fallen apart, and is that the large improvement of fuel contamination and management difficulty are large with bituminous coal, and mostly low-altitude discharged.Civilian bituminous coal stove and accessory belongs to ground proximity discharge.The harm cause environment and resident and pollution are far away higher than other combustion systems.
According to historical data estimation, combustion process produce atmosphere pollution account for 70% of total amount, its metabituminous coal discharge capacity then account for whole fire row high-volume 96%, so bituminous coal flue dust becomes the primary pollution source of China's air.China produces 90% of coal and is used as fuel, and wherein more than 70% is bituminous coal fuel, is made for civilian bituminous coal fuel and accounts for 28%.Although civilian bituminous coal proportion in whole bunker coal is not very big, but because Civil energy-saving cooking stove, tea furnace, life arcola burn insufficient, in addition chimney is short, not through the waste gas of desulfurization at low-altitude discharged, form low latitude surface pollution, so usually pollute for very more than industrial bituminous coal to the contamination hazard degree of residential block air, especially in the arcola winter heating phase of the civilian coal that to fall apart based on bituminous coal, civilian bituminous coal causes the main cause of atmosphere pollution especially severe especially.Simultaneously because Civil energy-saving cooking stove has a large capacity and a wide range, disperse very much, stove and accessory itself does not have desulphurization plant, administers more difficult yet, therefore more should cause the attention of each side.Administering bituminous coal pollutes very urgent, and administering bituminous coal pollution top priority is administer arcola.
Winter, the soot dust granule thing of coal heating discharge was one of main arch-criminal of environmental pollution, although city implements central heating on a large scale, the family of coal stove is used significantly to reduce, but in vast rural area, the heating mode still dominate of single household causes rural area and nearby urban air-polluting pollution sources.On rural market, more than 90% sale uses the stove and accessory of direct bituminous coal at present, this kind of stove and accessory not only thermal efficiency only has about 30%, and be take bituminous coal as fuel, with clean fuel-anthracite or moulded coal, heating installation all burns not hot, when especially using moulded coal to make fuel, because fire box temperature is low, cause burning insufficient, peasant is unwilling to use, clean fuel is promoted and is therefore faced with the low problem of stove and accessory product specification, adds difficulty to environmental improvement.And the Heating stove that Rural Areas at Present generally uses exists defects such as coal consumption is large, the thermal efficiency is low, pollutant discharge amount is large, contaminated environment, not only pollute environment, high flow rate and inefficient combustion system have also increased the weight of the burden of peasant greatly, make the rural area winter heating difficulty of some economically underdeveloped areas.
Mainly endotherm area design is less for existing stove and accessory, and exhaust gas temperature is higher.Absorber agent structure is flue gas and water flow direction is following current, many employings two backhauls or three backhauls, if reduce exhaust gas temperature, then structure can be more complicated, greatly need improve rolled steel dosage, causes cost to improve cost performance and reduces.Existing Domestic heating stove is not suitable for the anthracite briquette that burns, because if want moulded coal Thorough combustion, must reduce the flue dust initial ejection concentration of heating stove, the moulded coal used must have heat endurance.But if require that moulded coal has higher heat endurance, can not grill thoroughly, also just can not reach the nominal output of heating stove with existing common heating stove, dependence chemical addition agent technology can not from addressing this problem at all.
