Abstract
A process for preparing gas from combustible garbage by negative-pressure anaerobic thermolysis and gasifying includes such steps as preparing raw material, pulverizing, squeezing and enclosing, compression and exhausting, anaerobic gasifying in a furnace, cleaning gas and delivering gas. Its advantages are decreasing volume of garbage by 95%, high heat value and gasifying efficiency, and low cost.
Description
Technical field
The present invention relates to green technology, be mainly used in the harmless treatment of city combustiblerefuse, and produce the combustible gas byproduct.
Background technology
The harmless treatment of municipal wastes is the problem that various countries, the world today attach great importance to.In developed country, many-sided reasons such as the stoker fired grate incinerator is backward in technique because of it, performance is single, treatment effect is relatively poor are eliminated gradually, the fluidized bed type incineration treatment technology that replaces begins to occur, because this technology adopts malleation to burn principle and produces the combustible gas byproduct, combustiblerefuse is to burn than under the sufficiency at air, handle so can only adapt to the combustiblerefuse of high heating value, the combustible gas output capacity is lower.In addition.This cover processing method and equipment thereof can't adapt to China's combustiblerefuse high-moisture percentage, low-calorie actual conditions.
Summary of the invention
Purpose of the present invention is exactly at China's combustiblerefuse water ratio height, particular case that calorific value is low, design provides a kind of method with preparing gas from combustible garbage of suitable China's national situation, by adopting the principle and the method for incineration of combustible rubbish under negative-pressure sealing, the anoxia condition, handle the back when reducing quantity of refuse about 95%, produce the higher combustible gas product of a large amount of combustion values, reach that treatment effect is good, working procedure is simple, with low cost, make full use of the discarded energy, especially be fit to the purpose of China's national situation.
Design of the present invention is:
1, gets the raw materials ready.Rubbish is carried out sorting, combustiblerefuse is selected, and dry processing or need not processing, oven dry back or combustiblerefuse water ratio≤27% that need not to dry according to the water ratio of combustiblerefuse.
2, pulverize.The combustiblerefuse of water ratio≤27% is ground into granularity≤100 mm granules shapes.
3, extruding sealing, the body exhaust of contracting.The diffusing shape combustiblerefuse of granularity≤100 mm granules is sent in the extrusion equipment, be compressed into blocks, its density proportion is 800-1000 kilogram/rice
3, and with in the rubbish about 0.7 meter
3Air discharge, thereafter will not aeriferous rubbish blocks sealing sending in the equipment for gasification.
4, sealing is deblocked and is gasified, block combustiblerefuse is treated as the powder-shaped rubbish with good ventilation property through separating block assembly, directly enter in the gasification installation, combustiblerefuse carries out insufficient, incomplete combustion under anoxia condition, and generation inflammable gas, gasification temperature is up to 1000 ℃, and gasification back combustiblerefuse amount reduces about 95%.
5, gas-purification.Under the negative-pressure air fan effect.Washing purifying device is sent in the impure combustion gas that produces in the gasification installation, by water washing, water filtration and mechanical filter, 1/3-1/4 in second temperature reduce to about 70 ℃ by 1000 ℃, be cleaned into pure inflammable gas free from foreign meter.
6, combustion gas is carried, is stored.Under the vacuum suction of negative-pressure air fan, the combustion gas after purifying is sent in the combustion gas storage facilities by the road, or the direct sending user.The negative-pressure air fan maximum should provide the negative head of-3000 mmhg.
The present invention makes the city combustiblerefuse obtain innoxious, minimizing and recycling treatment and application, have the advantages that the garbage treating process flow process is simple, reasonable, effective, vaporization rate is high, running cost is cheap, especially can be fit to the gasification process of China's combustiblerefuse.
Embodiment
1, gets the raw materials ready.Rubbish is carried out sorting, combustiblerefuse is selected, and according to the combustiblerefuse water ratio or send into and dry processing in the drying plant, or avoid oven dry and handle, oven dry back or natural moisture content≤27% get final product.
2, pulverize.The combustiblerefuse of water ratio≤27% is processed pulverizing in disintegrating apparatus, make it become granularity≤100 mm granules.
3, extruding sealing, the body exhaust of contracting.The diffusing shape combustiblerefuse of granularity≤100 mm granules is sent in the rubbish compression assembly by e Foerderanlage, be squeezed into blocks through loam cake, side pressure cylinder and main hydraulic cylinder sealing successively, and with every meter
3In the rubbish about 0.7 meter
3Air discharge, its density proportion is at 800-1000 kilogram/rice
3, volume-diminished is sent into not aeriferous rubbish piece extruding in the rubbish briquetting sealing road that is about 3 meters thereafter to about 1/4-1/5 of original volume.
4, sealing is deblocked and is gasified.Rubbish piece in the rubbish briquetting sealing road rubbish that enters at interval is successively separated in the block assembly, be processed into powder-shaped rubbish with good ventilation property, directly enter in the negative pressure pyrolytic gasification assembly, under anoxia condition, combustiblerefuse carries out insufficient, incomplete combustion, and the generation inflammable gas, gasification temperature is up to 1000 ℃, and gasification back combustiblerefuse amount reduces about 95%.
5, gas-purification.The combustion gas that contains impurity that produces under the negative-pressure air fan effect, in the negative pressure pyrolytic gasification assembly enters in the gas-purification assembly through purifying the assembly inlet tube, earlier after water drenches mixing, water filtration, mechanical filter and water filtration for the second time, reduce to about 70 ℃ from 1000 ℃ in second at 1/3-1/4, suppress the synthetic of Dioxins, be cleaned into pure inflammable gas free from foreign meter.
6, combustion gas is carried, is stored.Under the vacuum suction of negative-pressure air fan, the inflammable gas after purifying is sent in the combustion gas storage facilities through the fans entrance pipe, or the direct sending user.The negative-pressure air fan maximum should provide the negative head of-3000 mmhg.
Refuse gasification pneumatolytic part that present method produces is as follows: CO
28.6%, ChHm4.6%, O
21.2%, CO17.5%, H
