Description
Background of invention
Along with the quickening of Urbanization in China, in city, the house refuse in city grows with each passing day.The method of disposal of current house refuse has two kinds: one to be the method adopting sanitary landfills; Two is rubbish is sent into waste incineration field to carry out burning electricity generation.The former not only takies a large amount of soils, and the percolate that refuse landfill produces causes severe contamination with the foul gas distributed to environment.The many countries in Europe have prohibited and have adopted the method for landfill to dispose domestic waste.Therefore, become uniquely can received refuse disposal method for current waste incineration and generating electricity process.Owing to containing the biodegradable rubbish such as a large amount of changing food waste (leftover, fruits and vegetables residue etc.), garden garbage and ight soil mud in domestic waste, make the water content of domestic waste mostly more than 50 percent.Although adopt the method for disposal of burning electricity generation to make waste reduction, but also the energy that can reclaim in rubbish realizes garbage as resource utilization.But, can not self-sustaining burning when the water content due to domestic waste is too high, additional coal or heavy oil just must can make incineration firing.In such cases, burning power plant has become in fact covert fire coal (oil) power plant.Research shows, incineration firing calorific value general lower (being less than 4000kJ/kg), and during burning, a large amount of heat energy is consumed in moisture evaporation, not only reduces generated energy, and adds incinerator construction and maintenance cost.Burning power plant produces one of inducement of dioxin especially.Burning power plant produces the percolate and stench that are difficult in a large number process in addition, is also degrading the environment around working environment and power plant.
Present invention is disclosed a kind of garbage dewatering device that the water content of domestic waste can be made to be reduced to less than 25%.Biomass garbage high for water content in rubbish is separated with other rubbish being difficult to be biodegradable by the crunch of 600 to 1000 kilograms every square centimeter that this device produces by means of hydraulic means.This device not only improves the calorific value of rubbish significantly, improves the generated energy of Unit Weight rubbish, and avoids the above-mentioned variety of problems without producing when squeezing the municipal solid wastes incineration power generation processed.
Domestic waste after the rubbish pressing device process that the present invention discloses is divided into two parts: a part is water content dry component that is very low, that form primarily of the component of refuse being difficult to be biodegradable (mainly plastics, paper, discarded rubber, discarded fabric and dehydration garden garbage etc.); Another part is water content wet component that is high, that be grouped in semi-solid, by the biodegradable one-tenth in domestic waste.The former, except as except high heating value fuel used to generate electricity, can also be made into garbage derivatived fuel, for needing other industrial department (as cement plant) of fossil fuel.The latter can produce biogas and fertilizer as the raw material of biogas fermentation.Thus reach the target of the completely innoxious of domestic waste and recycling.
