Description
Technical field
The utility model relates to a kind of suite of equipment for preparing block, bar-shaped biomass fuel with the mud and the domestic refuse of town sewage plant, realizes mud and Industrialization of domestic Refuse Disposal, integrated.
Background technology
At present, with technology and the equipment that the mud and the coal of domestic refuse, Sewage Plant prepares biomass fuel, existing both at home and abroad a lot of research.But they finally all are difficult to change into real productivity, trace it to its cause, and mainly have following problem:
(1) sewage quantity of dehydration procedure generation is too big.Domestic many scientific research institutions all make the biomass fuel technology at research and utilization rubbish and mud at present, and most of technological processs all have dehydration procedure.Moisture percentage in sewage sludge after Sewage Plant is handled is generally 80% ~ 85%(also to be had and is low to moderate 65%, but processing cost is higher).The water ratio of domestic refuse is generally about 45% ~ 55%, if rainwater more season may be higher.By producing calculating in domestic refuse 1.25kg/ days per capita, the city of one 500,000 population produces the domestic refuse amount every day and reaches 625 tons.Supposing that dehydration back msw water content is 20% ~ 25%, so only is garbage dewatering, and the sewage quantity that produce every day just reaches 250 ~ 300 tons.The burden of the sewage work that this increases the weight of has undoubtedly increased the cost of refuse treatment greatly.
(2) the roasting procedure operability to mud or rubbish is not strong, and the operation cost for the treatment of refuse is too high.Major part all can relate to mud or domestic refuse roasting procedure based on the technological process that domestic refuse, mud and coal prepare biomass fuel.In the actual production, 1 kg of water is become water vapour, needing current consumption is 1 degree.The domestic refuse water content generally about 45% ~ 55%, is reduced to just suitable burning below 15% if make fuel then need with its water content.Calculate by the domestic refuse production line of handling 150 tons every day,, then need current consumption 4.5 ten thousand degree nearly if the domestic refuse water content is reduced to about 15% ~ 20%.If do not add any supplementary additive, directly mud is toasted, not only cost is higher, and because the unusual thickness of mud, the direct baking mode fact proved it also is infeasible.Use natural air drying or sunlight to shine these modes, the production cycle is long.
(3) granularity is thin inadequately behind the refuse breaking, and molding procedure is difficult to realize.Domestic refuse is crushed to below the 5mm, and adds suitable adhesive and mix, be easy to make biomass fuel with coal.The method that domestic refuse is pulverized has grinding, extruding, broken repeatedly, and used machine is difficult to reach this and pulverizes requirement at present, and per hour power consumption is all more than 30 degree, and the domestic refuse of processing is all below 1 ton.Only this item energy consumption is just very high, causes the mass disposal domestic refuse infeasible basically.
(4) calorific value of synthol is too high.Because the synthetic fuel value all more than 5000 kilocalories, needs auxiliary fuel (as coal, the gasoline etc.) proportion of interpolation very big, general enterprise or cities and counties' finance are difficult to bear.
