Abstract
The invention relates to a garbage processing technology of garbage processing equipment, and belongs to the technical field of garbage processing. The technology comprises steps of sorting, grinding, magnetic screening, gravity separating, and blank making. In the provided technology, waste metals, ceramics, construction wastes, coal residues, and soil are mixed and made into brick blanks, the wastes are reasonably recycled; the wastes are not buried directly, the polluted land is reduced; the inorganic wastes are not burned directly, while the inorganic wastes are carbonized to prepare burning gas, the generated heat can be used to heat the anaerobic reaction tank, and thus the energy used for garbage treatment is reduced.
Description
Technical field
The present invention relates to a kind of garbage treating process of refuse treatment plant, belong to waste processing arts.
Background technology
As everyone knows, along with Process of Urbanization Construction progress faster, increased population, Municipal Garbage Yield sharply increases.According to statistics, in the 80's of 20th century, National urban rubbish annual production is about 1.15 hundred million tons, has reached 1.43 hundred million tons to the 90's.Current domestic annual municipal refuse generation is at about 1.8 hundred million tons.Predict 2030, Chinese MSW research produces total amount per year will reach 4.09 hundred million tons.Current China domestic waste besieged city, has become the thorny problem of urban construction and management, at present in more than 600 big and medium-sized cities, the whole nation, has 2/3 to be absorbed among the encirclement of rubbish, and has the city of 1/4 not have good place heap garbage.The disposal of current rural garbage is except minority village adopts simple waste landfill, major part rural garbage is all stack everywhere, mainly incline to place is " hexagon ": roadside, river bank, limit, village, Tian Bian, the side of a pond, limit, room, form severe contamination, endanger the life and health of people, destroy simultaneously and affect living environment, becoming broad masses and governments at all levels and pay close attention to and focus in the urgent need to address and difficulties.
In the last few years, our Environmental protection, and gave great attention to the process of domestic waste, and drop into a large amount of financial resources, material resources, manpower carry out administering and controlling.Because relevant laws and regulations system is not well established, treatment facility and technology relatively lag behind, and also can reach far away ideal effective processing intent.The rto request that this and domestic rubbish disposal are walked " innoxious, minimizing, resource, industrialization " differs greatly.How harmless treatment is carried out to house refuse? and secondary pollution is reduced in processing procedure? how effectively can process house refuse and create comparatively considerable economic benefit again? in a word, this millstone around one's neck of disposal of refuse is become tempting business opportunity, reach the object of environmental protection, benefit doulbe-sides' victory, this is the hot issue that leaders is all extremely paid close attention to.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, proposes a kind of low power consuming and the garbage treating process of the refuse treatment plant of non-secondary pollution.
The present invention is the technical scheme solving the problems of the technologies described above proposition: a kind of garbage treating process of refuse treatment plant, comprises the following steps:
(1) classify: house refuse is divided into more than inorganic refuse, plastic garbage, kitchen and biologic garbage by sub-sieve mechanism;
(2) pulverize: by pulverizer by more than inorganic refuse, plastic garbage, kitchen and biologic garbage pulverize respectively;
(3) magnetic separation: inorganic refuse is sent into magnetic separation storehouse and carry out magnetic separation, isolate metal wherein;
(4) specific-gravity winnowing: inorganic refuse is sent into air separating bin and carry out specific-gravity winnowing, is separated pottery wherein and building waste;
(5) embryo processed: magnetic separation metal garbage out and specific-gravity winnowing pottery out and building waste and gangue and soil are carried out being mixed and made into brick embryo, wherein the mass ratio of metal garbage, pottery, building waste, gangue and soil is 1:3:3:2:5;
(6) carbonize: be that the ratio of 1:1:1 mixes with mass ratio by inorganic refuse, plastic garbage and charcoal, be heated to the 900-1000 DEG C of obtained combustible gas of charing reduction;
(7) more than kitchen, send into anaerobic reaction groove with biologic garbage, add sewage, use above-mentioned combustible gas for the heat supply of anaerobic reaction groove, keep the temperature of anaerobic reation pool between 35-40 DEG C;
(8) anaerobic reaction groove top is every being provided with catalyst tank, adds palladium grain in catalyst tank;
(9) in anaerobic reaction groove, pass into displacement mist, described displacement mixing gas component is 85% N
2, 10% CO
2with 5% H
2;
(10) product of anaerobic reaction groove after anaerobic reaction is carried out dewatered drying, obtained organic fertilizer.
The improvement of technique scheme is: when combustible gas is the heat supply of anaerobic reaction groove in step (7), burn the waste gas that produces successively by after dedusting, washing and desulfurized step by smoke stack emission.
The improvement of technique scheme is: be provided with rabbling mechanism in step (7) anaerobic reaction groove, stirs material in anaerobic reaction groove.
The improvement of technique scheme is: anaerobic reaction gained methane is used in step (6), for charing provides heat.
The present invention adopts the beneficial effect of technique scheme to be: (1) metal garbage, pottery, building waste and gangue and soil carry out being mixed and made into brick embryo, have carried out rational re-using, have not had direct landfill, decrease the waste of land resource to rubbish; (2) inorganic refuse does not directly burn, but by obtained for inorganic refuse charing combustible gas, is the heat supply of anaerobic reaction groove, decreases the energy that garbage disposal consumes; (3) anaerobic reaction groove top is every being provided with catalyst tank, can accurately control catalyst use amount, makes reaction more efficient; (4) product of anaerobic reaction groove after anaerobic reaction is carried out dewatered drying, be made as fertilizer, kitchen is remaining passes through the reasonable back to nature of anaerobic reaction with biologic garbage, decreases secondary pollution.
Detailed description of the invention
