Abstract
The utility model discloses a domestic garbage treatment device which is composed of a sorting pool (1), an incinerator (3), a flue gas purifying device (5), a quench cooler (6), a chimney (8), a blending and homogenizing pool (9), a fermenting pool (10), a settling pool (11), a clear liquid pool (12) and a clear liquid reflux pump (14). The domestic garbage treatment device has the beneficial effects of low garbage treatment energy consumption, small occupied area, no secondary pollution and no requirement on water content and calorific value of garbage entering a plant; fermentation gas, namely methane generated in a fermentation process is used as an auxiliary fuel of the incinerator, and therefore self-supplying of the auxiliary fuel required by garbage incineration can be realized; and flue gas of the incinerator repeatedly reflows to preheat garbage and simultaneously prolong the retention time of flue gas, and organic matters can be sufficiently pyrolyzed.
Description
Technical field
Domestic garbage disposer adopt to do that wet Unareobic fermentation handles that the kitchen is surplus, ight soil, fruits and vegetables and stalk rubbish, and the biogas of generation partly is used for combustiblerefuse and burns auxiliary fuel, and the outer defeated peasant household of part uses; Combustiblerefuses such as stained waste paper, packing material and plastics adopt burning disposal, and smoke backflow is guaranteed the abundant pyrolysis of the pollutant that produces in the burning process.Adopt wet anaerobic fermentation-pyrolytic process can make the waste reduction maximization, realize treatment of wastes with processes of wastes against one another purpose.
Background technology
China rural area house refuse amount per capita is 0.86kg, and people in the countryside are according to 6.57 hundred million, and then the annual generation of life in the countryside rubbish is 5.65 * 109kg.At present, the processing mode of life in the countryside rubbish is generally random stacking and collects the stacking mode, wherein arbitrarily stacks to account for 36.72%, collects stacking station 63.28%.That carries out landfill disposal in the rubbish that collection is stacked accounts for 57.03%, burns and accounts for 14.26%, and During High-Temperature Composting accounts for 13.88%, directly utilizes to account for 14.83% ［ 1 ］ again.This shows, life in the countryside rubbish has nearly four one-tenth to be dealt carefully with, in the house refuse of collection and treatment, employing land-fill method over half is arranged, take a large amount of soils, and most of landfill is to adopt simple the covering, its secondary pollution is more serious, and percolate can't be accomplished qualified discharge, and the environmental ambient air quality descends, mosquitos and flies grows and causes transmission, and some available materials do not have reuse.
There is strict technical stipulation in China to the garbage loading embeading place, and its addressing is one of subject matter of sanitary filling field construction, is subjected to the double constraints of land used character and environment protectment protection, and vast rural area also is not easy to find suitable garbage loading embeading place.Waste incineration is a kind of life refuse processing method preferably, can make the waste reduction maximization, and its fume afterheat can be realized comprehensive utilization.But waste incineration requires high to incinerator, and charging calorific value, water content are all had relatively high expectations, and bioxin control is the difficult point of waste incineration.Be subjected to the influence of resident living mode, China's house refuse composition is with different abroad, and its distinguishing feature is a rubbish water content height, and calorific value is lower.Therefore, simple consumer waste incineration need add the auxiliary fuel of some, as coal, natural gas.
For big-and-middle-sized refuse-burning plant, add a certain proportion of fire coal in the rubbish, it is necessary improving the calorific value of going into stove fuel, and is acceptable aspect Technological Economy.But concerning vast rural area, waste treatment facility relatively disperses, and is small, improves refuse thermal value if rely on the interpolation auxiliary fuel, keeps waste incineration, obviously is infeasible at economic aspect then, nor tallies with the national condition.This technology adopts house refuse fermentation-burning integral technology on the basis that takes into full account China's life in the countryside component of refuse characteristics, realize the target of life in the countryside rubbish " resource, minimizing, innoxious ".
The utility model content
The utility model provides a kind of domestic garbage disposer, mainly is after allowing house refuse march into the arena, to sort, and metal, building castoff that the plastics that proportion is lighter, packaging bag, paper and proportion are bigger are separated from rubbish.
The utility model main feature is: by the letter sorting pond, incinerator, smoke eliminator, quencher, chimney, mediation homogeneous pond, fermentation vat, sedimentation basin, clean solution tank, the clear liquid reflux pump constitutes, letter sorting Chi Youxiajiaochu is provided with an incinerator, between letter sorting pond and the incinerator spark arrester is set, its incinerator top is provided with a feeding warehouse, the incinerator right side is provided with a smoke eliminator, one smoke backflow blower fan is set between its incinerator and the smoke eliminator, the smoke eliminator right side connects a quencher, the quencher right side is provided with a chimney, one exhaust blower is set between its quencher and the chimney, one mediation homogeneous pond, its top, mediation homogeneous pond is provided with a screening, mediation right side, homogeneous pond connects a fermentation vat, the fermentation vat right side connects a sedimentation basin, the sedimentation basin right side connects a clean solution tank, the clean solution tank right side is provided with a clear stream and goes back to the pump pond, between its sedimentation basin and the mediation homogeneous pond sludge pump is set.
The beneficial effects of the utility model are: the garbage disposal energy consumption is little, takes up an area of to lack non-secondary pollution; Water content, calorific value to the rubbish of marching into the arena do not require; The fermentation gas biogas that sweat produces is as the auxiliary fuel of incinerator, and the required auxiliary fuel of waste incineration is realized confession; Incinerator smoke refluxes repeatedly, is used for garbage pre-heating, increases gas residence time simultaneously, fully pyrolysis of organic matter; Adopt smoke pre-heating that the fermentation vat feed liquor is carried out adjustment, the fermentation vat temperature constant, factor of created gase is higher; The reuse of fermentation raffinate part only effluxes on a small quantity, need not sewage treatment facility; Fermentation residue enters incinerator, realizes minimizing to greatest extent; Incinerator residue can be used as construction material.
