Abstract

The invention discloses a comprehensive treatment and utilization method for urban garbage, which comprises the following steps of: firstly, placing garbage in a garbage dumping site into a roller sieve for carrying out screening treatment; carrying out separated treatment on building garbage screened by the screening treatment; carrying out deironing treatment on garbage left after the building garbage is screened and conveying scrap iron into a metal recycling system; conveying the garbage deironed by a deironing system into a manual sorting classification system; conveying organic garbage into a methane fermenting system by manual sorting; communicating a methane conveying pipe of the methane fermenting system into a boiler burning chamber of a thermoelectric system; conveying the inorganic garbage into a recycling oil refining system by manual sorting; conveying sorted metal into a metal recycling system by the manual sorting classification system; conveying sorted glass, and the like into a recycling system by the manual sorting classification system; conveying manually sorted garbage into a garbage crushing system; and conveying the garbage crushed by the garbage crushing system into the boiler burning chamber of the thermoelectric system. The invention can effectively solve the problem of blocking a deslagging system of a garbage boiler, greatly reduce water content in the garbage and the running cost of a garbage power plant and improve the comprehensive utilization effect of the garbage.

Description

The method that a kind of municipal refuse integrated treatment utilizes
Technical field
The present invention relates to the method that a kind of municipal refuse integrated treatment utilizes, is that a kind of utilization screening, method for sorting carry out rubbish biogas fermentation, reclaim comprehensive utilization method such as oil refining, burning electricity generation.
Background technology
At present, the recirculating fluidized bed refuse-burning plant that the whole nation puts into effect, the cycle of operation is all shorter, mainly because of being owing to garbage sorting is not thorough, stops up the slag system that removes of garbage fired boiler, by the slag system that removes of forced-stopping machine cleaning boiler.For a long time, the cycle of operation of refuse-burning plant is short, operating cost is high, rubbish comprehensive utilization weak effect has become a difficult problem.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art; Provide a kind of and can effectively solve the problem of removing slag system of stopping up garbage fired boiler; Can reduce the operating cost of refuse-burning plant, improve the method for a kind of municipal refuse integrated treatment utilization of rubbish comprehensive utilization effect.
The object of the invention can be realized through following technical scheme:
The method that a kind of municipal refuse integrated treatment utilizes, concrete processing method is following:
A, at first whenever in the 3-5 kilometer range, set up a point to collect municipal refuse in each small towns, subdistrict office;
B, rubbish is entered the storehouse, is promoted to conveyer belt with grab bucket and is transported to rotary screen and carries out sub-sieve:
(1) size is got into drying system less than rubbish below 200 millimeters; Size is sorted processing greater than 200 millimeters rubbish;
(2) filter out size through sub-sieve and carry out individual processing, recycle greater than 200 millimeters building waste;
(3) all the other rubbish entering deironing systems carry out the deironing processing, and the scrap iron that the deironing system clears is sent into the metal recovery system, and the rubbish that carries out after deironing is handled through the deironing system gets into manual sorting's categorizing system;
(4) through manual sorting's categorizing system organic wastes such as the living beings that sort out, pericarp, spoil are sent into the organic waste treatment system; The organic waste treatment system is sent organic waste into marsh gas fermenting system, and the biogas carrier pipe of marsh gas fermenting system feeds the boiler Burning Room of heat and power system;
(5) through manual sorting's categorizing system inorganic refuses such as the waste or used plastics that sorts out, rubber are sent into the inorganic refuse treatment system, the inorganic refuse treatment system is sent into inorganic refuse and is reclaimed low temperature distillation system;
(6) through manual sorting's categorizing system the metal that sorts out is sent into the metal recovery system;
(7) through manual sorting's categorizing system the glass that sorts out is recycled;
(8) send into the refuse breaking system through the rubbish behind the manual sorting, the boiler Burning Room that the rubbish after the fragmentation of refuse breaking system is sent into heat and power system burns.
The present invention compared with prior art has can effectively solve the problem of removing slag system of stopping up garbage fired boiler, can significantly reduce the moisture content in the rubbish, can reduce the operating cost of refuse-burning plant, improves the advantage of rubbish comprehensive utilization effect.
Description of drawings
Accompanying drawing is a system schematic of the present invention
The specific embodiment
The method that a kind of municipal refuse integrated treatment utilizes; At first be place where the garage is piled up to be put into rotary screen carry out sub-sieve; Through sub-sieve the building waste of size greater than 200 millimeters screened; The building waste that screens carries out individual processing can carry out brickmaking, system ash etc.; Filtering out rubbish behind the building waste gets into magnet absorption type deironing system and carries out deironing and handle; The scrap iron that the deironing system clears is sent into the metal recovery system, and the rubbish that carries out after deironing is handled through the deironing system gets into manual sorting's categorizing system, through manual sorting's categorizing system organic wastes such as the living beings that sort out, pericarp, spoil is sent into the organic waste treatment system; The organic waste treatment system is sent organic waste into marsh gas fermenting system; The biogas carrier pipe of marsh gas fermenting system feeds the boiler Burning Room of heat and power system, through manual sorting's categorizing system inorganic refuses such as the waste or used plastics that sorts out, rubber is sent into the inorganic refuse treatment system, and the inorganic refuse treatment system is sent into inorganic refuse and reclaimed distillation system; Through manual sorting's categorizing system the metal that sorts out is sent into the metal recovery system; Through manual sorting's categorizing system the glass that sorts out etc. is sent into recycling system, send into the refuse breaking system through the rubbish behind the manual sorting, the rubbish after the fragmentation of refuse breaking system is sent into the boiler Burning Room of heat and power system.
