The device includes material loading machine, dry broken system, pyrolysis gasifier, combustion chamber and tail gas and waste residue clean system, and gasification is separated with waste conveying to the pyrolysis gasifier internal heat by screw feeder after getting into the material loading machine at last to rubbish, the gaseous steady voltage gas pitcher 12 that gets into behind burnt oil filter of pyrolysis, and the combustible gas in the steady voltage gas pitcher passes through 13 burnings of pipeline entering combustion chamber to produce a large amount of heat energy, again the heat supply separate and utilize in the gasifier, realize heat energy cyclic utilization. The filter passes through ca (OH) 2 and active carbon neutralization reaction, can get rid of the harmful gas of HCL, HF, SO2 in the flue gas, and discharge to reach standard can be realized to the device flue gas exhaust emission thing, does not have waste water, waste gas production in the processing procedure.

Description

Portable rural garbage pyrolysis gasifying device

Technical field

The present invention relates to a kind of portable rural garbage pyrolysis gasifying device.

Background technology

Collect owing to China's residents in rural community distributional region is wide, difficult, existing equipment for treating rural garbage needs collective conveyance to reclaim, and process mainly through landfill, compost and three kinds of modes of direct burning, consume a large amount of soil, energy and cause that secondary pollution is serious. At present, the refuse collection amount about 3.6 hundred million tons that the whole nation is annual, wherein county town, villages and small towns rubbish account for 60%, and treatment scale is less and harmless treatment rate is relatively low. All the time, due to small movable rubbish processing to be harmless technology and equipment restriction, rural garbage treatment facility slower development.

Compared to the mode directly burned, pollution effects is good, volume reduction effect is notable, resource recovery is high because controlling for refuse pyrolysis gasification technology, it is described as best and effective waste disposal method, obtain substantial amounts of application and development rapidly in developed country, technology reaches its maturity, and mainly includes refuse pyrolysis gasifying process and refuse gasification smelting process. Due to features such as China's rural garbage high-moisture, low heat value and classification not yet in effect, refuse pyrolysis gasification technology is more suitable for China rural garbage and processes.

For predicaments such as wide, the difficult collections for residents in rural community distributional region, reduce garbage collecting and transferring and cost of disposal, rural garbage is overcome to burn the secondary pollution brought, in the urgent need to developing a kind of convenient, simple to operate, high-efficiency cleaning flexibly and investment and the relatively low technology of garbage disposal of operating cost and equipment, really to realize rural garbage harmlessness disposing, conscientiously improve Ecological Environment.

Summary of the invention

In order to solve the problems referred to above, a kind of mobile garbage pyrolysis gasifying device of special offer.

This device includes: feeder 1, dry crushing system, pyrolysis gasification furnace 6, combustor 13 and tail gas and waste residue cleaning system, wherein:

Dry crushing system is sequentially connected with is formed by 1# feed bin 2, disintegrating machine 3,2# feed bin 4, screw feeding machine 5,

Tail gas and waste residue cleaning system include spiral tapping machine 7, waste residue bucket 8, cyclone dust extractor 9, filter 10, tar filter 11, voltage stabilizing gas tank 12, and described cyclone dust extractor 9, filter 10, tar filter 11 and voltage stabilizing gas tank 12 are linked in sequence by pipeline;

Screw feeding machine 5 connects the upper end of pyrolysis gasification furnace 6, and the lower end of pyrolysis gasification furnace 6 has Single port to be connected with combustor 13, and the bottom discharge mouth of pyrolysis gasification furnace 6 is connected with spiral tapping machine 7; Pyrolysis stove 6 upper end has Single port to be connected with cyclone dust extractor 9;

Discharging opening bottom described spiral tapping machine 7 is connected with waste residue bucket 8;

Described combustor 13 is connected with voltage stabilizing gas tank 12 by pipeline.

After rubbish enters feeder 1, sequentially pass through 1# feed bin 2, disintegrating machine 3,2# feed bin 4, last by screw feeding machine 5, rubbish is transported to pyrolytic gasification in pyrolysis gasification furnace 6, the waste residue produced in pyrolytic gasification process is escaped and enter waste residue bucket 8 by spiral tapping machine 7, dust in flue gas coordinates the activated carbon powder absorption solving injection on the stokehold end pipeline that gasifies to catch the heavy metals such as two English in flue gas and some gaseous mercuries, effectively contains the harmful gas generations such as two English. Producing substantial amounts of pyrolysis gas in pyrolytic gasification process to be collected by cyclone dust extractor 9, after pyrolysis gas removing dust, sequentially enter filter 10, tar filter 11 by pipeline, filter passes through Ca (OH)₂With in activated carbon and reaction, HCL, HF, the SO in flue gas can be removed₂Etc. harmful gas, the tar that pyrolytic process is produced by tar filter processes. Pyrolysis gas enters voltage stabilizing gas tank 12 after tar filter, and the fuel gas in voltage stabilizing gas tank enters combustor 13 by pipeline and burns, and produces a large amount of heat energy, can again utilize in pyrolysis gasification furnace, it is achieved heat energy recycling.

The advantage of this device:

(1) this apparatus structure is compact, floor space 6M*2M*4M, can vehicle-mounted mobile operation, reduce garbage transportation cost.

(2) this device all utilizes pyrolysis smoke to be dried in continuous feed and shattering process, and the msw water content of gasification furnace can be controlled within 20%, by agitating device interior in gasification furnace, can increase refuse pyrolysis efficiency. System output pyrolysis gas is stable, it is possible to effective guarantee gasification furnace pyrolysis heat supply, reduces blowing out charging and lets out the heat-energy losses of slag, it is achieved high efficiency of energy utilizes.

(3) this device smoke emissioning pollution thing such as CO, HCL, SO₂、NO_X, flue dust, two English, heavy metal Hg, Cd, HCL, Pb etc. can realize qualified discharge, processing procedure produces without waste water, waste gas.

Detailed description of the invention

Rubbish is carried into 1# feed bin from feeder, through disintegrating machine carry out broken after enter 1# feed bin, and be transported in pyrolysis gasification furnace by screw feeding machine. Along with the stirring of body of heater, the rubbish added in stove uniformly can be sprinkling upon on any one surface in its cross section along burner hearth edge grain. Rubbish, in pyrolytic gasification process, is brought rapidly up being dried and evaporating moisture content by the effect of high-temperature flue gas stream from bottom to top. Pyrolytic gasification process produces substantial amounts of pyrolysis gas through cyclone dust extractor, enter filter and tar filter carries out particulate matter and tar processing, process combustible pyrolysis's gas after finishing and enter voltage stabilizing gas tank. When being increased to more than 600 DEG C along with temperature, substantial amounts of Organic substance starts decomposition gas chemical conversion CO, H_2、The combustible gases such as CmHn the high-temperature flue gas along with rising enter combustion chambers burn and produce a large amount of heat energy.

Carrying out along with dry thermal cracking, refuse pyrolysis temperature raises further, the vigorous combustion such as remaining carbon residue, tar release substantial amounts of heat after organic matter decomposition gasification, these heats rubbish for just entering stove again provides its heat energy needed for dry intensification and pyrolytic gasification process, it is possible to achieve heat energy recycling.

Hot-engine sludge after oxidizing fire in continuing to move down by lower and on air cool down, the residue after cooling falls in waste residue bucket after being processed by whirlwind slag remover.
