Abstract
The invention discloses a process method for producing fuel rods by using sludge and living garbage and relates to a process method for producing fuel rods by mixing the sludge produced by sludge treatment projects and the urban and rural living garbage. The method of the invention is as follows: (1) the sludge produced by a sludge treatment project is dried to ensure that the water content of the sludge is between 10 and 20 percent for standby; (2) the urban and rural living garbage is transported into a garbage pre-placement basin and conveyed to a conveying belt for initial sorting; (3) the obtained urban and rural living garbage through the sorting undergoes coarse crushing, the particle size reaches 3 to 5cm, then the magnetic separation is performed so as to further sort and remove the fine iron; (4) the moisture of the living garbage after a magnetic separation is removed by adopting a drying or sun exposure or extrusion method to ensure that the water content of the garbage is less than 10 to 20 percent, then the fine crushing is made to ensure that the particle size reaches 1 to 2cm; and (5) the dried sludge and the living garbage made a fine crushing are mixed, and an extruding machine is adopted to make an extrusion molding to produce fuel rods after the mixing; the weight percentages of the sludge and the living garbage are that: the sludge is between 5 and 95 percent, and the garbage is between 5 and 95 percent.
Description
Technical field
What mud of the present invention, domestic refuse technique for producing fuel stick related to is a kind of mud of sewage disposal project generation and processing method of the mixed fuel stick of urban and rural domestic refuse utilized.
Background technology
Along with the fast development of economic construction and improving constantly of exhausting level, the life structure and the level of consumption are progressively improved, the increase of various material consumptions, and sanitary sewage, domestic refuse composition are changing, and output is also rising year by year.
At present, China's town domestic sewage annual production per capita is 45 tons, and existing big and medium-sized cities all have the sanitary sewage disposal project, the small city is also progressively being built, the part small towns also has the sewage disposal project, but problem of ubiquity, how the mud after the sewage disposal is disposed.Because of through the sludge moisture content after the processed between 70-80%, and there is several factors in dehydration again, is to adopt filling type basically, brings pollution to environment.
The annual production per capita of China's municipal wastes is about 0.5 ton, and the rubbish annual production in the whole nation is up to more than 200,000,000 tons, and is increasing progressively with the speed of annual 6-10%.Rubbish storage over the years is up to 6,000,000,000 tons, about 750,000 mu of appropriation of land area.In 668 cities, the whole nation, there be more than 200 city to be among the encirclement of rubbish approximately.
Mud, domestic refuse are the chief culprits of city environmental pollution, not only destroy urban ecology, the infringement investment environment, hinder urbanization process, influence the economic construction Sustainable development, and serious harm greenbelt atmosphere and water quality, threatening city resident's quality of life and safety.
The sewage disposal scale is increasing, and each county is all building sewage work, and developed regions town township level is all built the sewage disposal project.But sewage after treatment, the same problem that becomes a headache of people with domestic refuse of the mud of its appearance.
Scientific and effective sludge of sewage treatment plants, the domestic refuse handled well become the focal issue that countries in the world are paid close attention to.And innoxious, the minimizing of mud and rubbish, resource utilization, recycling treatment, the direction that current just environmental protection industry (epi) is broken through.
Summary of the invention
The objective of the invention is provides a kind of mud, domestic refuse technique for producing fuel stick at above-mentioned weak point, be a kind of with mud and domestic refuse technique for producing fuel stick that sewage disposal produced, this processing method is the method for a kind of scientific and effective processing mud and rubbish, can reach mud and garbage harmless, minimizing, resource utilization, recycling treatment, current just environmental protection industry (epi) is broken through, mud and rubbish can be turned waste into wealth, therefrom develop mud and consumer waste regenerated fuel stick.
Mud, domestic refuse technique for producing fuel stick take following scheme to realize: mud, domestic refuse technique for producing fuel stick is characterized in that:
1, the mud oven dry that the sewage disposal project is produced makes its water content standby at 10-20%;
2, urban and rural domestic refuse is transported rubbish and preset the pond, domestic refuse is delivered to conveying belt carries out preliminary sorting, wherein metallic substance, glass, building waste are sorted out and deliver to the regeneration of regeneration unit;
3, will carry out coarse reduction through the urban and rural domestic refuse that branch was chosen, granularity reaches 3-5cm, carries out magnetic separation again, so that the further sorting of tiny irony is removed;
4, will adopt oven dry or Exposure to Sunlight or fashion of extrusion to remove moisture through the domestic refuse of magnetic separation, the water content that makes rubbish be less than 10-20%, and fine powder is broken again, makes granularity reach 1-2cm;
5, with the mud of above-mentioned oven dry with through the broken domestic garbage mixing of fine powder, mix the back and adopt the extrusion machine extrusion molding, mud, domestic refuse system fuel stick; Wherein mud, domestic refuse weight percent proportioning are: mud 5-95%, rubbish 5-95%.Mud, domestic refuse system fuel stick density reach 0.6-1.5g/cm
3Mud can increase the density of mud and domestic refuse shaped fuel rod, and it is broken that it is difficult for, and mud can play cohesive action in extrusion machine extrusion molding process.
Described mud, domestic refuse system fuel stick calorific value reach 1600-4000 kilocalorie/kilogram.Mud, domestic refuse system fuel stick can be used as fuel and directly burn.
Mud of the present invention, reasonable in design, the technological process science of domestic refuse technique for producing fuel stick, can at utmost make mud and rubbish obtain regeneration, can do the essence change to mud and domestic refuse pollution on the environment, be the Sustainable development of society.Because the simple science of process for making, can save a huge sum of money that in mud and domestic rubbish disposal, expends, and mud and rubbish are turned waste into wealth, develop mud and consumer waste regenerated fuel stick is made fuel.Innoxious, the minimizing of mud of the present invention and rubbish, resource utilization, recycling treatment, the direction of current just environmental protection industry (epi) development.
