In recent years, though also being arranged, the infusion of financial resources of a lot of enterprises is engaged in the research of treatment of urban garbage technical elements, perhaps investment construction comprehensive garbage disposal factory, part offshore company has also entered this field, but from the project operation effect of building up in recent years, not very desirable, be to have problems above the technology on the one hand, though some technology starting point is than higher, from external introduction, move very successful abroad, to not being fine in the domestic operating performance of China, the batch production on-road efficiency is poor on the other hand, and product marketing is not smooth, factory can't survive, and causes stopping production.In general, no matter domestic city domestic rubbish disposal aspect still is the industry aspect from technology, still is in the starting stage, also is not formed with the group of enterprises of certain scale and benefit, and most of enterprise also is in the stage of fumbling.
Summary of the invention
The purpose of this utility model is to provide a kind of gasification treatment device for household refuse, so that can effectively handle domestic refuse, makes domestic rubbish disposal be developed to the comprehensive utilization of resources direction by single treatment technology.
The gasification treatment device for household refuse that the utility model proposes, by discharging hopper 1, feeding machine 2, refuse grinder 3, trommel screen 4, magnetic separator 5, water extracter 6, whizzer 7, rubbish briquetting press 8, vapourizing furnace 9, tornado dust collector 10, electric fishing Jiao 11, heat exchanger 12, washer 13 and adsorption tower 14 are formed, wherein, discharging hopper 1 is positioned at feeding machine 2 tops, feeding machine 2, refuse grinder 3, trommel screen 4, magnetic separator 5, water extracter 6, whizzer 7, rubbish briquetting press 8 passes through pipe connection successively, rubbish briquetting press 8 is by pipe connection vapourizing furnace 9 tops, vapourizing furnace 9 tops are by pipe connection tornado dust collector 10, tornado dust collector 10 bottoms are by burnt 11 tops of pipeline electric fishing, burnt 11 bottoms of electric fishing are by pipe connection heat exchanger 12 tops, heat exchanger 12 bottom wash devices 13 tops, washer 13 bottoms connect adsorption tower 14, and whizzer 7 is by pipe connection heat exchanger 12 middle parts.
In the utility model, feeding machine 2 adopts apron feeder.
In the utility model, vapourizing furnace 9 bottoms are provided with gas blower.
Advantage of the present utility model:
Carry out comprehensive treating process after the refuse classification, realize the regeneration of recyclable resource to greatest extent;
Recyclable resource classification in the rubbish is handled and utilized, improve the economic value added that reclaims resource to greatest extent, turn waste into wealth.
Unique gasification technology can be realized the clean conversion of the energy of flammable class material in the rubbish and utilize, the systemic contamination of effectively avoiding other processing mode to produce, defectives the such as especially discharging of Dioxins will be than burning low order of magnitude, and the investment of having avoided the burning mode to bring is big, secondary pollution is serious.
Project is convenient to canalization production, and good perfect waste water and flare system makes factory reach the ecological, environmental protective standard, and non-secondary pollution produces, and good operation and Working environment is provided simultaneously.
Entire treatment factory more easily implements overall monitor, and the level of automation height is convenient to centralized management and control.
Description of drawings
Fig. 1 is a structural diagrams of the present invention.
Number in the figure: 1 is discharging hopper, and 2 is feeding machine, and 3 is refuse grinder, and 4 is trommel screen, and 5 is magnetic separator, 6 is water extracter, and 7 is whizzer, and 8 is the rubbish briquetting press, and 9 is vapourizing furnace, and 10 is tornado dust collector, 11 are electric fishing Jiao, and 12 is heat exchanger, and 13 is washer, and 14 is adsorption tower.
Embodiment
Further specify the utility model in conjunction with the accompanying drawings below by embodiment.
Embodiment 1: as shown in the figure, at first, enter the discharging hall after the domestic refuse metering, pour discharging hopper 1 into, discharging hopper 1 is arranged on apron feeder 2 tops, domestic refuse enters refuse grinder 3 via apron feeder 2, combustiblematerials is crushed to the granularity of easy drying and shaping, enters trommel screen 4 after the fragmentation, screen overflow is via magnetic separator 5, remove metal, remaining combustiblematerials enters feed bin.Screen underflow is via magnetic separator, remove metal, through the moisture in the water extracter 6 reduction rubbish, rubbish after the dehydration and the combustibleconstituents in the screen overflow enter whizzer 7 after mixing, rubbish enters in the rotating cylinder from leading portion, the rotation of rolling therein, thermally equivalent, high-temperature flue gas (temperature can reach 400-500 ℃) by engine exhaust enters in the rotating cylinder from the back segment adverse current, rubbish in the rotating cylinder is carried out drying, water ratio is reduced to 18-25% from 40%-50% in the rubbish, for follow-up rubbish briquetting press 8 is laid a good foundation.
Rubbish briquetting press 8 mainly is to carry out forming processes at the combustiblematerials that produces in the pre-treatment process, (shape particle and promptly become RDF), and its main purpose is that combustiblematerials processing is generated garbage derivatived fuel, is called for short RDF.RDF be to combustiblematerials dewater, desulfurization, dechlorination handle, and form through the brute force compression, be a kind of homogeneous, the good fuel of combustionproperty, its calorific value improves greatly, small-particle and air contact surface are big, sufficient combustion, make efficiency of combustion improve greatly, can realize high-temp combustion; Because of having removed SOx and Cl-wait the Dioxins precursor, the quantity discharged of dioxin nuisance also reduces greatly in the gasification, and the flue gas that produces behind the fuel gas buring does not need complicated processing, and the pollution of environment has been dropped to minimum level; RDF is a kind of be convenient to store transportation, clean fuel ordorless, with long preservation period.The RDF of moulding deposits after cooling.
The RDF that rubbish briquetting press 8 is produced sends in the fixed-bed gasification furnace 9 by lift, vapourizing furnace is a vertical structure, skin is a steel plate, interior cun refractory materials, it is combustion-supporting to send into little air by the bottom high pressure blower, emit heat,, and make the vapourizing furnace gasification temperature be controlled at 800-1100 ℃ with pyrolysis and the moisture evaporation institute heat requirement of supplying raw materials.Under the high temperature anaerobic environment, raw material is broken down into CH through processes such as super-dry, pyrolysis, gasification and burnings
4, H
2, CO
2, small molecules inflammable gass such as CO.The residue that gasification produces is discharged through furnace bottom rotary fire grate and scraper slagging machine, delivers to the residue brick equipment to produce building materials.
The combustion gas of coming out from vapourizing furnace 9 at first enters tornado dust collector 10, remove macrobead, comparatively clean gas enters electric fishing burnt 11 subsequently and captures tar, gas enters heat exchanger 12 then, because the flue-gas temperature of the discharge of vapourizing furnace is up to 500 ℃, in order to utilize waste heat better, the high-temperature flue gas of the discharge of vapourizing furnace by heat exchanger 12, is added the dry materials that is used for pre-processing device behind the warm air.Enter washer 13 and adsorption tower 14 again through the flue gas after the cooling process, by water smoke washing and adsorption dual effect, combustion gas is further purified, and clean combustion gas is delivered in the gas storage holder by roots blower and stores.
