Abstract
The invention discloses a household garbage low-temperature pyrolysis system and method based on process decoupling and scrubbing combustion. Household garbage is sent into a drying drum to be dried firstly and then sent into a pyrolysis drum to be pyrolyzed, so that pyrolysis gas and carbon residues are generated. Drying and pyrolysis are divided into a starting stage and a normal operation stage. During the starting stage, air and gas output by a gas storage device are mixed, pass through a combustor of the drying drum and a combustor of the pyrolysis drum and burn in a cavity of the drying drum and a cavity of the pyrolysis drum correspondingly to supply heat, and accordingly high-temperature smoke is generated. During the normal operation stage, the high-temperature smoke in the cavity of the pyrolysis drum is sent into the cavity of the drying drum to be subjected to heat exchange and drying, and the combustor of the drying drum becomes an auxiliary heat source. The pyrolyzed gas is purified through a moving bed adsorption device, a plasma scrubbing device and a moving bed absorption device, and finally, the smoke and the pyrolyzed gas are subjected to waste heat recovery in a gas and smoke waste heat exchanger. According to the household garbage low-temperature pyrolysis system and method, waste heat is sufficiently utilized to generate high-temperature steam, the smoke is exhausted after being cooled and purified, the generation of dioxin is effectively controlled, and resource recovery, reduction and low carbon of the household garbage are achieved.
Description
Technical field
The present invention relates to domestic garbage was harmlessly treated and resource recycling utilizes technology, particularly belong to a kind of Kernel-based methods decoupling and the house refuse low temperature pyrogenation system and method for gas washing burning.
Background technology
Now, China produces to exceed the domestic waste of 200,000,000 tons every year, and the annual rate of growth of rubbish has reached more than 10%.In recent years, although the process of China's domestic waste achieves certain effect, but overall capacity is also substantially not enough, the growth rate of garbage disposal ability substantially lags behind the growth rate of refuse production, a large amount of domestic wastes cannot be processed in time and are piled up in countryside, having occupied large area soil, urban is faced with the threat of " garbage-surrounded city ".
At present, in China or even world wide, widely used Treatment Way of Municipal Refuse in City mainly has landfill, burning, three kinds of compost, and wherein landfill is the major way that China processes domestic waste, and garbage treatment quantity constitutes about the 80% of rubbish total amount.But, the shortcoming such as the methane gas aggravation greenhouse effect that the processing mode of landfill exists that land occupation resource is big, leachate contamination, fermentation produce.Then there is the problems such as floor space is big, conversion process time length, state are difficult to stably, product quality is wayward in the processing mode of compost, simultaneously, the rubbish of China's compost treatment essentially composting, not past strict classification, therefore composting process is mixed into unavoidably a large amount of such as poisonous and harmful substances such as heavy metals, add the methane isothermal chamber gas uncontrollable discharge of generation, very easily surrounding enviroment are caused severe contamination.In above-mentioned three kinds of modes, burning method is the processing mode that garbage decrement effect is best, rubbish volume reduction 85%, loss of weight more than 75% can be made, but burn away the refuse and there is the hidden danger of contaminated environment, especially two English burning generation have irreversible " three cause " toxicity, health is had great harm, has become the most noticeable problem at present.In addition, the burning disposal of rubbish there is also some restrictions:
(1) domestic waste of China substantially mixed collection, complicated component, and burn the minimum calorific value generally requiring rubbish at 3360kJ kg-1Above, it is accomplished by when the calorific value of rubbish is too low adding fuel with auxiliary combustion, so will result in the increase of operating cost, current China is except the more flourishing city of minority economy, the separate waste collection in other city is not yet generally carried out, therefore mixed consumer waste calorific value is all relatively low, is not suitable for burning；
(2) investment of burning disposal equipment and operating cost are all higher, and mostly what the garbage incinerating power plant that China builds early stage was introduced is foreign technology and equipment, and investment cost is expensive；Recently as introducing equipment production domesticization and technological self-innovation, domestic technology and equipment develop to some extent and apply, though the investment of incineration plant unit decreases, but for the general area of ability to shoulder economically, the investment of burning disposal and operating cost are still high.
For burning method, now more advanced pyrolytic technique is the decomposition reaction carried out under the reproducibility environment of anaerobic or anoxia, not only there is the minimizing feature the same with burning method, and the secondary pollution emission of substance of its generation is less, therefore has good application prospect.Additionally, the form that the utility in refuse is converted into gaseous state (combustion gas) or liquid (tar) by pyrolytic technique is utilized respectively, these gaseous states and liquid fuel are higher than the direct efficiency of combustion of solid waste, pollute lower.At present, domestic had certain research to refuse pyrolysis treatment technology, if publication number is CN103242134A, name is called the patent of invention of " one way of life refuse pyrolysis gasification purification method ", the method disclosed in the patent is to introduce oxygen under 900 DEG C of hot conditionss to carry out burning cracking reaction, the fuel gas synthesis industrial chemicals that comprehensive utilization refuse pyrolysis produces, realize the resource of house refuse, but the complicated component due to house refuse, the combustible gas component of its pyrolysis generation and ratio also relative complex thereof, therefore this adds difficulty for synthesis industrial chemicals, and in high temperature aerobic situation, process rubbish, its follow-up purification process costs is higher, exhaust emissions amount is also bigger.Such as publication number is CN102660306A again, name is called the patent of invention of " reversely flow back towards and turn domestic garbage pyrolysis retort system and garbage treating process ", this patent technique is to carry out pyrolytic reaction under 400 DEG C of oxygen free conditions, utilize pyrolysis gas burning supplemental heat source, realize minimizing and the resource of rubbish, but house refuse is not dried pretreatment by this technique, but the mode that employing pyrolysis limit, limit dries, this can increase the energy consumption of system and reduce treatment effeciency, after substantial amounts of flue gas cool-down process simultaneously, directly atmospheric environment also can be affected by discharge, particularly by the society of haze puzzlement, the subsequent treatment of flue gas can not be ignored.Therefore, for the problem that existing patented technology and application thereof presently, there are, further investigation processes technique with improving refuse pyrolysis, reduce the generation of secondary pollution emission of substance, reduces vent gas treatment difficulty further, has important Science & Society's economic implications.
