Description

Domestic waste pyrolysis fuel oil equipment

Technical field

The utility model relates to a kind of domestic waste pyrolysis fuel oil equipment.

Background technology

Domestic waste is one of three major types solid waste, and it derives from refuse that daily routines human and animal produce in the city or the Litter that does not re-use.Like the residue in kitchen, the paper product that abandon, the electronic product of scrapping, the wrapping material of commodity etc., along with the development of urbanization process is rapid, the domestic waste generation also increases rapidly, according to statistics annual more than 100 hundred million tons of the solid waste that increase newly in the whole world in 2010.In the face of the severe situation that domestic waste produces, its treatment technology, the developed country such as the U.S. are just being made great efforts to explore in the whole world; Canada, Japan, Germany; The proposition early of states such as France through comprehensive treating process, realizes waste reductionization on the categorised collection basis of realizing rubbish, innoxious; The thinking of resource utilization, and set up quite complete separate waste collection system for handling.Make a general survey of global developed country and China's garbage treatment state of the art, see table 1, can find, mainly take at present to burn landfill, 3 kinds of comparatively common processing modes of compost.

Table 1 world major country process for treating urban garbage

Country Landfill % Burn % Compost % The U.S. 75 10 5 France 40 38 22 Holland 45 51 4 Germany 65 32 3 Austria 59.8 16.2 24 Sweden 35 55 10 China 92 3 5

From table 1, can find out, China, the U.S. and part European countries landfill disposal are still occupied bigger ratio, but compost, burning disposal has also occupied certain ratio.

1. landfill: landfill be organic composition in the domestic waste under the anaerobic condition of landfill yard, the process of decomposing through anaerobion.It is simple that landfill disposal has technology, and cost is lower, extremely wide to the adaptation of rubbish, need not carry out advantages such as sorting to rubbish; At present, landfill is the main method of garbage treatment.Although it is simple to operate that the garbage loading embeading processing has, cost is low, adapts to extremely wide advantage, simultaneously secondary pollution is arranged also, and occupies a large amount of land resources.

2. compost: the producing fertilizer from refuse in daily life treating processes is exactly to rely on the bacterium that extensively distributes voluntarily; Actinomycetes; Mikrobes such as fungi; Under certain artificial condition, controlledly promote and its essence is a kind of fermenting process by the organism of verivate degraded to the Biochemical processes that stable detritus transforms.The biologic garbage composting technology has realized the recovery of resource, has reached the requirement of technology of garbage disposal resource utilization, has promoted the benign cycle of nature material, and its volume generally is the 50%-70% of original volume after the employing compost treatment.For landfill,, when solving refuse treatment, realized the resource utilization target although compost is a kind of ecological technology of garbage disposal that requires that meets most.But it is big that the compost treatment technology exists facility investment, long processing period, and treatment capacity is little, and because some heavy metal can accumulate in soil, makes that the heavy metal content in the soil obviously improves, the problem of serious threat food chain.

3. burn: burning is a kind of domestic waste to be carried out the chemically treated technology of elevated temperature heat.As burning in the solid fuel input incinerator equipment, flammable composition and airborne oxygen in the domestic refuse carry out violent chemical reaction, discharge heat and high-temperature combustible gas body and a spot of solid lime-ash with domestic refuse.The high-temperature combustible gas body that incineration firing produces can be used as energy generating and utilizes.Through burning disposal, decompose, destroyed being harmful in the rubbish, toxic waste and various stench, utterly destroyed bacterium, virus, burning disposal can make rubbish loss of weight 70%-75%, decrement 80%-92%.But often contain obnoxious flavour such as SO in the combustion tail gas that discharges in the burning disposal process 2, HCl, NO X, CO and dioxin-like chemical (PCOD S/ PCDF S) etc., the lime-ash of discharging contains a large amount of heavy metals and dioxin-like chemical etc. especially therein, if deal with improperly, all will produce secondary pollution, and therefore, discharging how to control noxious just becomes the key of consumer waste incineration.

Along with the progress of society and the renewal of idea, the raising of the development of urban economy and resident living level, the domestic waste day output increases considerably, and the proportion of combustiblesubstance is also increasing in the rubbish composition.How to handle these total amounts in hundred million tons, produce continually, the domestic refuse of serious environment pollution has become one of major issue of countries in the world city management.At present the waste disposal method that extensively adopts of countries in the world is sanitary landfill, and compost burns these three kinds of technology and all exists innoxious not thoroughly, and the resource utilization degree is low, and running cost is high, can't suppress to burn the dioxin-like chemical (PCOD that brings S/ PCDF S) discharge, the sour gas discharging, the heavy metal volatilization is shifted and the enrichment secondary pollution problems.Therefore, countries in the world are just striving to find more advanced domestic rubbish disposal technology.Refuse gasification generating and gasification and melting incineration technology are a new generation's technology of developing at present.Characteristics such as but because the domestic waste calorific value is low, water cut is high, and combustiblematerials is few make this binomial technical economic benefit poor, the industrial applications difficulty.

The master data of domestic waste is at present:

The average combustion heat value of composting: rubbish wet basis low value thermal value is 800-1000 card/kilogram

Msw water content 40-60%, unit weight are 0.4 kg/liter

Organic content in the rubbish: about 62%

According to above-mentioned data,, in the pyrolytic gasification process, need to absorb a large amount of heats if adopt the refuse pyrolysis gasification technology; And synthetic gas is with water vapor and combustible gas and deposit, therefore, and the synthetic gas calorific value that refuse gasification obtains lower (being generally 4-6MJ/Nm3); Be used to generate electricity its generating efficiency at 10-15%; Deficiency in economic performance can only be used for resident's heating, supply energy sources such as cooking air feed.And gasification and melting incineration is technological owing to its fusion in reactor drum, and temperature is more than 1300 ℃.The refuse gasification burning does not reach high like this temperature, needs extra other fuel that replenishes, and causes economic benefit low.

Summary of the invention

In order to overcome innoxious not thorough that prior art exists, the resource utilization degree is low, and running cost is high, can't suppress to burn the dioxin-like chemical (PCOD that brings S/ PCDF S) discharge; The sour gas discharging; Heavy metal volatilization is shifted and problems such as enrichment secondary pollution, economic benefit be low, and the utility model provides a kind of low heat value that can make, high-moisture; The domestic waste that combustiblematerials is few is utilized more fully, makes the domestic waste pyrolysis fuel oil equipment of its maximization of economic benefit.
