Description

A kind of sludge cooperates with innocuity disposal system with stalk

Technical field

The utility model belongs to environmental technology field, and in particular to a kind of sludge cooperates with innocuity disposal system with stalk.

Background technology

Inevitable outcome of the municipal sludge as sewage treatment plant is city domestic sewage and industrial wastewater in processing procedure Caused solid waste.With the development of society and gradually stepping up for living standard, the yield of municipal sewage is also increasingly increasing It is long, so as to result in the increase of municipal sludge yield.By taking 20,000 tons/d municipal administrations water factory as an example, dewatered sludge amount about 6- is produced daily 10 tons, according to statistics, the sludge quantity that China is discharged every year at present is about 22,000,000 tons (moisture content is based on 80%), and so quantity is huge If big municipal sludge, which cannot get appropriate disposal, to cause secondary pollution to environment.Containing in municipal sludge largely has Machine thing, there is higher calorific value, can directly burn or with other biological matter mixed combustion；Contain abundant nitrogen phosphorus in sludge simultaneously Deng materials such as nutrients, heavy metal and pathogenic bacteria and pathogens, if dealt with improperly, it will ecological environment is caused seriously to endanger Evil.

The mud being widely used at present mainly has landfill, compost and burning.But in view of existing water factory's addressing Limitation, typically then can be more troublesome to remote landfill yard transported great, particularly mountain area；And due to Sludge landfill bearing capacity Difference, secondary pollution problems, more refuse landfill are reluctant recovery landfill or improve disposal costs substantially.Therefore, with filling out Bury and compared with compost, sludge incineration can volume reduction to greatest extent, the volume for the remaining ash content that burns is only the 10% of initial volume, Pathogen after burning in sludge is thoroughly killed, and the stability of heavy metal improves, and reduces landfill and heap to a certain extent During fertilizer may the pollution problem to caused by underground water, while can also realize the recycling of the energy.It is studies have shown that dirty Mud is individually burned then there is the problems such as energy consumption, equipment requirement height and combustion instability, and therefore, sludge pollution has become public affairs One of subject matter of crowd's concern.

At present on the basis of traditional mud, many researchers both domestic and external to sludge it is innoxious, Minimizing, stabilisation, recycling etc. have carried out more exploratory developments.Such as sludge is used to prepare building materials, cracking liquefaction Or some sorbing materials etc. are prepared, but the studies above is not got a lot of applications.

Biomass fuel is a kind of regenerative resource, is referred to by sun photosynthesis and caused various organic substances, It is a kind of form of energy that solar energy is present in the form of chemical energy among biology, directly or indirectly from the light of plant Cooperation is used.Biomass be considered as be only second to coal, oil and natural gas and occupy the energy of world energy sources total quantity consumed the 4th Source, there is distribution extensively, the big advantage of reserves.Biomass is as the macromolecular organic conjunction that organic matter fuel is by Various Complex The complex of thing composition, chemical composition mainly have：Cellulose, hemicellulose, lignin and extract etc., these polymer substances Also different in variety classes biomass, its composition of the different zones of one species biomass, some even have very big difference.

Biomass can typically divide following 4 major class：1. lignin：Wooden unit, wood chip, bark, tree root etc.；2. agricultural wastes： Stalk, fruit stone, corncob, sugarcane skin slag etc.；3. water plant：Algae, water hyacinth etc.；4. oil crops：Cottonseed, numb seed, oil Paulownia etc..The combustible component of biomass is mainly organic element such as carbon, hydrogen, nitrogen and sulphur.Although for the composition of element, biomass The composition and conventional fuel coal of fuel substantially have no difference, but the difference of exactly each composition quantitatively result in biology The difference of combustion product and coal processed.The carbon content of biomass is generally 50% or so, and less than common bituminous coal, and hydrogen content is then It is significantly larger than common bituminous coal higher than bituminous coal, especially fugitive constituent and oxygen content, oxygen content exceedes 10 times or so of coal.Due to biomass The combustible component content of fuel compares relatively low, therefore the low heat valve of biomass fuel is lower than general bituminous coal.In combustion of catching fire Aspect of performance is burnt, the volatile content of biomass fuel is significantly larger than common bituminous coal, causes ignition performance apparently higher than general Logical bituminous coal.In terms of burning pollutant generates discharge, the sulfur content of biomass fuel is only 0.1% or so, nitrogen content and theory Nitrogen volume is also below bituminous coal, so total SO₂And NO_xGrowing amount is all far below bituminous coal.Volatilized according to straw biomass fuel is high Point, high oxygen amount, the fundamental characteristics of low-sulfur part and ash, therefore for coal, straw biomass has inflammable, wiper ring The characteristics of guarantor.Currently, the consumption of biomass fuel has accounted for the 14% of total worldwide energy consumption, in this ratio of developing country more It is to reach 38%.Predict according to the World Food Programme (FAO), will be provided to regenerative resource of the year two thousand fifty based on biomass energy The electric power in the whole world 60% and 40% fuel, its price are less than fossil fuel.Therefore, the utilization of biomass fuel have been As the common recognition in the world.

China is a large agricultural country, possesses abundant agricultural straw resource, the north mainly using wheat, maize straw as It is main, and south is then based on straw.According to statistics, the annual production of the existing agricultural crop straw in China is about 700,000,000 tons, and stalk has heat It is worth higher and combust also higher advantage.But because people comprehensively utilize understanding deficiency to stalk resource, cause straw The utilization rate of stalk is very low.Meanwhile crop straw burning and the phenomenon that arbitrarily abandons are also of common occurrence, are not only to agricultural straw resource Significant wastage, and also result in environmental pollution.

Therefore, many technique that ginseng burning collaboration processing is carried out using sludge and stalk has been developed in the prior art, has been led to The DTG curves for crossing test sludge and stalk find that after single mud sample catches fire, its burn rate is not high, it is impossible to quick Higher ignition temperature is formed, and combustion process is uneven.And after mixing stalk, the volatile matter in stalk is largely analysed in low-temperature space Go out and burn, add the severe degree of reaction so that ignition temperature, duration etc. meet some in sludge than stronger , the burning condition of stable compound, it is horizontal so as to improve the combustion stability of aggregate sample and after-flame；And mixed with stalk The increase of mixed ratio, the combustibility index increase of aggregate sample, combustibility have been lifted.

But research is, it was also found that the integrated combustion property exponential quantity of single stalk sample is higher than sludge, it is possible the reason for be The temperature of volatile ingredient and burning in stalk is more concentrated, and most of volatile component is fast in 200-500 DEG C of temperature range The precipitation and burning of speed, after sample catches fire, high temperature can be rapidly formed until after-flame.And then because organic matter forms in sludge Relative complex, the chemical bond of each composition is strong and weak different, and it is separated out and burning point is located at different temperature sections, and because of its precipitation and combustion Not concentrating for temperature is burnt, have impact on the stability of its burning.Therefore, burned if sludge and stalk are directly entered into stove jointly, not only Its combustibility can be produced more serious sintering phenomenon by extreme influence.
