Description
Technical field:
The present invention's " manufacture method of household garbage fuel and application thereof " belongs in environmental protection department's domestic rubbish disposal technology category doing method and the application thereof that raw material is made household garbage fuel with domestic refuse." domestic refuse " described here mainly refers to: " the domestic refuse waste after recycling ".
Background technology:
What China mainly adopted in to the method for domestic rubbish disposal at present is landfill and burning method.Landfill method be one allow domestic refuse dewater naturally, corrupt naturally, discharge gas, reduce the process of volume.Its shortcoming is: mosquitos and flies breeding ground, bacterial reproduction base, a waste water complicated component, continue to distribute defective such as foul smell, land resources occupancy be big.In innocent treatment procedure, burning domestic garbage should be a best way, but in the burning process of the consumer waste incineration field of having moved at present owing to produced new dioxin gas, so have different versions in evaluation to burning method.By analysis, one of gordian technique of present burning domestic garbage: all be to have adopted coal or oil fuel to make the method that the ignition dope domestic refuse that water ratio is very high is directly burned.Its approach one is: ignition dope and the heat that sends by the burning of ignition dope under certain condition after domestic refuse is mixed are mutually evaporated the burning of the moisture re-initiation domestic refuse in the domestic refuse, and this method needs a large amount of ignition dopes.Its approach two is: the burning of the moisture re-initiation domestic refuse in the burning heat direct baking domestic refuse that ignition dope the sent evaporation domestic refuse.Present burning method is equivalent to a fresh Chinese cabbage is placed directly in the stove hall of boiler, and incinerate this Chinese cabbage then needs long time and a lot of fuel.Therefore it is high to exist power consumption in present burning method, the defective that the time is long.Power consumption is high, long the not scientific of burning process that also reflected of time.Reflect according to data: the sulphur in currently used incineration technology ignition dope has play in incineration process of domestic garbage from a kind of activator effect of new synthetic dioxin gas, and contain in the domestic refuse chlorine plastics, to mix in domestic refuse chlorine-containing organic compounds be root from new synthetic dioxin gas.No chlorine just can not produce dioxin gas, and conversely, the effect of not having sulphur even chlorine has been arranged will lack catalytic condition from new synthetic dioxin gas.Therefore it will be argued that: currently used incineration technology is a kind of burning method of burning domestic garbage.For seeking not produce second kind of consumer waste incineration method of dioxin gas, to seek one exactly and make ignition dope without coal or oil fuel, that is to say the incineration technology that in burning process, should dodge element sulphur as far as possible and again consumer waste incineration be fallen.The present invention's's " manufacture method of household garbage fuel and application thereof " purpose just is this.
Summary of the invention:
The notion that relates to herein, what is " household garbage fuel "? making directly with domestic refuse as raw material, burnt fuel is called household garbage fuel.Here " domestic refuse " refers to: do not had the value of recycling and do not belong to poisonous and hazardous domestic refuse waste by people's appellation so far after recycling processing.For example: vegetables, pericarp, shell, leftovers, leftovers and human and animal excreta etc.
As everyone knows, straw and straw that common water ratio is lower than about 10% just can directly burn through lighting the back under certain condition, when water ratio also can burn under simple combustion-supporting condition about 15%.Vegetables, pericarp, shell, leftovers leftovers or the like domestic refuse waste is the same with straw and straw, about being lower than 10%, water ratio maybe can store through just can directly burning after lighting under certain condition, when water ratio also can burn under simple combustion-supporting condition about 15%.This is that the present invention does the theoretical foundation that raw material can produce " household garbage fuel " with domestic refuse.
As everyone knows, if get one section fresh sugarcane, wild rice stem, vegetables as if finding in the burner hearth that is placed on boiler: they may also will be difficult to burning than coal, and its residue that promptly enables to burn lumps often or stays the imperfect combustion thing.Its reason is that water ratio is too high.Then need long time and a large amount of ignition dopes if will fully burn.Do you notice the process of people at the fresh sugar cane juice of street corner cash sale in order to address this problem? they get one section fresh sugarcane and are placed on a very little roll mechanically with hand moving just obtaining the sugar cane juice of one glass of deliciousness and the bagasse that a slice promptly will be dropped after the hand channel squeezing.If bagasse is placed on Exposure to Sunlight under the sun or in drying tunnel after baking for some time then bagasse can become fuel easily as straw or straw.In like manner if with vegetables in squeezing machine through the squeezing after, its residue can become fuel equally.Make ultimate principle and the method that raw material is made household garbage fuel with domestic refuse among the present invention that Here it is.
The basic characteristics of domestic refuse are: the water ratio height, have up to more than about 80%; Its intractability of sewage that is produced after the domestic refuse corruption is more much higher than the sewage disposal difficulty that is squeezed out before corrupt, and its combustion heat value also will descend widely.Therefore the principle of making household garbage fuel is: in time collect letter sorting in time, squeezing in time, in time baking.
The basic skills that the present invention makes " household garbage fuel " is: with the physical method that squeezes and toast it has been carried out the physical process of a forced dehydration according to above-mentioned principle.Here the implication of " dehydration " refers to: reduce water ratio.Its core key technology is: domestic refuse has been taked the repeatedly technology of forced dehydration.The physical process of forced dehydration is for the first time: the different sorts according to domestic refuse can adopt different machinery to squeeze.For example most domestic refuse can adopt the hydraulic machinery milling process.That is to say, domestic refuse is positioned over earlier in the foraminous container, this container is positioned in the hydraulic machinery again and squeezes, the moisture in the domestic refuse just can promptly flow out in large quantities under strong pressure, and domestic refuse is pressed into very low bulk of water ratio or sheet then.For example the fiber-like domestic refuse suits to adopt roll machinery milling process.The suitable evaporation of changing food waste and human and animal excreta with centrifuge dehydration machinery.These some measures can make the 50-70% that can descend rapidly of the water ratio in the domestic refuse not wait.For the second time the physical process of forced dehydration is the residue behind the first time forced dehydration to be placed baking makes it further reduce water ratio in the drying tunnel, so that improve combustibility and storability, finally becomes product " household garbage fuel ".Heat in the drying tunnel is from burning domestic garbage fuel.
Embodiment:
Relating to " application " among the present invention's " manufacture method of household garbage fuel and application thereof " refers to: proposed a kind of new way and novel method to domestic rubbish disposal; Its product is a household garbage fuel.And one of main outlet of household garbage fuel, just one of embodiments of the invention are exactly: build " the consumer waste incineration field of no ignition dope ".
Should " the consumer waste incineration field of no ignition dope " be the whole process making household garbage fuel and incinerate whole household garbage fuels.The consumer waste incineration field of this no ignition dope does not need with coal, fuel wet goods ignition dope; The purpose of making household garbage fuel is for convenience of burning domestic garbage, and burning domestic garbage fuel is to provide guarantee for making household garbage fuel.The heat that recovery burning domestic garbage fuel is sent at first guarantees to make the needed heat of household garbage fuel, and unnecessary heat just can be considered other purposes.
“”：————、 （ ） —— （ ） —— （ ） —— （ ， ） —— （ ） ———— （ ） ——。
The heat energy utilization that is somebody's turn to do " the consumer waste incineration field of no ignition dope " is: at first guarantee to make the needed heat of household garbage fuel.Account for about 1/4 of quantum of output through the needed household garbage fuel of estimation baking domestic refuse residue.The heat energy that is to say the household garbage fuel about 3/4 can be considered other purposes, for example: generating.This is the cogeneration of burning domestic garbage fuel truly.Its heat of cogeneration in existing consumer waste incineration field mainly comes from ignition dope.This is another difference of the different burning method of two classes.
About " incinerator " that relates in " operational scheme ": the incinerator of indication is dried fuel of burning or the stove that approaches dried fuel here.Can utilize coal firing boiler at present if consider the comprehensive utilization of heat temporarily." the boiler dedicated of household garbage fuel of burning " then awaits next step exploitation.
About drying tunnel, drying tunnel is a heat exchanger.Residue moves further transpiring moisture by travelling belt in the pyritous drying tunnel, become household garbage fuel the most at last.High temperature heat source can be taken from the heat of incinerator flue or the hot water or the superheated vapour of boiler.When high temperature heat source was taken from the heat of incinerator flue, half of drying tunnel just become an integral part of incinerator chimney.Smoke prevention and dust control problem to the incinerator chimney has had proven technique, no longer describes in detail here.Position as for device for eliminating smoke and dust is provided with problem, is explained as follows at this, if first dedusting then is difficult for the knot ash in the drying tunnel before drying tunnel, but the temperature of baking is lower, and output is also lower; If behind drying tunnel dedusting then in the drying tunnel temperature higher, output is also more higher, but the cleaning flue dust is cumbersome.
About sewage handling problem, suggestion inserts the municipal wastewater pipe network with sewage.If there is not this condition then mainly to take acid-base neutralisation and sterilising treatment, be not described in detail in this.
About making the needed origin of heat problem of domestic refuse of toasting first in " household garbage fuel " process after squeezing, then need other fuel of some amount to substitute household garbage fuel temporarily.
This consumer waste incineration field is a kind of consumer waste incineration field of not having ignition dope.It is effectively to suppress the effective measure that dioxin gas produces that its meaning is without coal, oily ignition dope, and has saved the energy widely.This is a kind of not only nuisanceless but also safety and be energy-saving brand-new consumer waste incineration method.
Except its advantage also show:
1, equipment is simple, the disposal ability height. In time collect the timely processing of house refuse and can effectively prevent life rubbish The corruption of rubbish effectively overcomes the foul smell that the corruption because of house refuse produces, regeneration and the breeding of bacterium.
2, can reduce widely cost of investment. Large-scale consumer waste incineration from ground imports such as Beijing, Shanghai , build at least 5 hundred million yuan of the burning field gross investment of day burning amount about 1,000, specific investment cost Volume up to 500,000 yuan/, invest very expensive. If building equally day burning amount according to method of the present invention exists Burning field about 1,000 is about 20 mu of floor space then, about 5,000 ten thousand yuan of gross investment, unit investment quotas only 5 Ten thousand yuan/about, that is to say you introduce one I can build 10.
3, burning of the present invention field, owing to do not need coal and fuel oil, so can reduce widely operation Cost. In the consumer waste incineration field of using, need every year government finance to paste money at present, almost do not have one Individual is the profit that belongs to truly. If implement burning of the present invention, then will have can for this situation Can be able to acquire change.
4, burning of the present invention field, its construction scale is changeable, and the construction period is short, and is flexible. Because foul smell is little, to pollute and lack, sewage disposal is convenient, small-scale can the construction on the spot.
