Abstract
The invention discloses a kind of residents in rural community distributed treatment technique, it is that rural area or residents from villages and towns house refuse are subjected to small-scale regional processing harmless on the spot according to its present position, multiple spot distribution is carried out according to its residing region and treats its natural air drying, after air-drying again by drying, the technique such as broken compacting powder-shaped rubbish derivatived fuel is made（RDF‑4）Or block rod solid waste derivatived fuel（RDF‑5）RDF fuel thermal decompositions are gasified, it is pyrolytic gasification heat supply to light pyrolytic gasification gained fuel gas, and caused heat smoke is dried to rubbish body, tail gas is dried through spray process such as calcium hydroxides, so as to reach the technique effect that fume emission will not cause secondary pollution.The present invention can be directed to the characteristics of rural area and small towns house refuse are more scattered and solve the demand of its garbage disposal, be widely used in the garbage disposal in China various regions rural area and small towns；Treatment in situ, saves cost of transportation, and the good flue gas of garbage disposal effect will not cause secondary pollution.
Description
Technical field
The present invention relates to the processing technology field of biomass, more particularly to a kind of residents in rural community distributed treatment work
Skill.
Background technology
With the fast development of China's economy, the domestic waste yield in China increasingly increases, the processing of rubbish and place
Put and have become China big and medium-sized cities and must solve the problems, such as；China's municipal refuse annual production at present about to 1. 5 hundred million tons, and
Also increasing year by year.To solve this problem, China is specially provided with environmental protection department and corresponding scientific research institution, or even urges
The public and private enterprise for specializing in environmental protection and garbage disposal is given birth to, the processing mode of house refuse is also more scientific, harmless
Change and recycling.These advanced garbage treating process and large-scale refuse disposal system disclosure satisfy that the place of domestic waste
Reason demand.
And compared to big city for, the domestic rubbish disposal in rural area and small towns is not then to be paid attention to very much, and the agriculture in China
Village and small towns often occupy the major part that population still accounts for total population, and rural area and small towns house refuse cannot timely and science processing
Cause agricultural pollution in rising trend, crops and food-safety problem are increasingly becoming the weight for influenceing the life health of our people
Want the stumbling-block of factor and socio-economic development.The house refuse in rural area and small towns is few unlike domestic waste, but there is also
The characteristics of its own, such as：The distribution of rural area and small towns house refuse is relatively broad, in big city at the centralized collection of rubbish
Manage and the processing mode of recycling can not be applied to rural area and small towns, for this reason, it is necessary to be directed to residents in rural community amount
The characteristics of big and widely distributed, designs special process.
The content of the invention
It is applied to rural area it is an object of the invention to provide one kind and small towns house refuse carries out distributed life in the countryside
Rubbish distributed treatment technique.
The above-mentioned purpose of the present invention is realized by following technical proposal：
A kind of residents in rural community distributed treatment technique, including following steps：
1）Small towns house refuse is subjected to multiple spot distribution according to its residing region and treats its natural air drying, makes to air-dry the aqueous of rear rubbish
Rate is down to less than 40%；
2）By step 1）House refuse after natural air drying, which is sent into mechanical drying roller, is dried；
3）Will be through step 2）Domestic garbage crushing after drying is less than 5cm granulated garbage into maximum particle diameter；
4）By step 3）Gained granulated garbage is sent into bar-producing machine and powder-shaped rubbish derivatived fuel is made after broken（RDF-4）Or block is bar-shaped
Solid waste derivatived fuel（RDF-5）；
5）By powder-shaped rubbish derivatived fuel（RDF-4）Or the bar-shaped solid waste derivatived fuel of block（RDF-5）It is sent into pyrolysis gasification furnace
Carry out pyrolytic gasification；
6）By step 5）Fuel gas obtained by pyrolytic gasification is passed through combustion chamber and lighted；
7）By step 6）Flue gas caused by gas fuel burning is passed into step 2 as drying heat source gas in combustion chamber）'s
In mechanical drying roller；
8）By step 7）Wet gas caused by middle mechanical drying roller drying rubbish is passed into cyclone dust collectors and carries out whirlwind
Dedusting；
9）Using the mode of aqua calcis spray to step 8）Wet gas after cyclone dust removal carries out desulfurization depickling processing,
Discharged after up to standard.
Further, step 1）It is middle that small towns house refuse is treated into its natural wind according to its residing region progress multiple spot distribution
It is dry, the moisture content of rubbish after air-drying is down to less than 35%.
Further, step 3）The middle granulated garbage that Domestic garbage crushing after air-drying is less than to 5cm into maximum particle diameter.
Further, step 9）Middle aqua calcis is formed by the saturated solution dilution of calcium hydroxide under normal temperature, its
Percent dilution is：Contain 20% ~ 60% calcium hydroxide saturated solution in per 100g solution.
Further, the step 9）Middle aqua calcis be by under normal temperature calcium hydroxide saturated solution dilution and
Into its percent dilution is：Contain 40% calcium hydroxide saturated solution in per 100g solution.
The beneficial effects of the invention are as follows：The characteristics of rural area and big but more scattered small towns house refuse amoun can be directed to, solves
The demand of its garbage disposal, it is widely used in the garbage disposal in China various regions rural area and small towns；Treatment in situ cost is relatively low, rubbish
High treating effect smokeless will not cause secondary pollution.
