Abstract
The present invention relates to a technological method for thermal decomposition distilling treatment of urban house refuse. The method treats the house refuse in the processing steps of crushing, magnetically separating, screening, squeezing, dewatering, distilling, cooling, pulverization, etc. Because of the processing steps of magnetically separating and screening, the method effectively recovers useful objects, and because coarse materials are sorted by adopting an artificial method and a water-suspension method, the method makes use of the characteristic of water and also reduces secondary pollution from recovered objects. The method greatly reduces treating cost by using marsh gas generated by the treatment of squeezing liquid as heating raw materials for the processing steps of dewatering and distilling, and is favorable for the circulating use of resources for the reason that house refuse dregs can be used as materials for making bricks.

The objective of the invention is to provide a kind of heating up in a steamer of pyrolysis treatment process method of domestic waste.
To achieve these goals, the present invention realizes by following process:
With domestic waste through fragmentation, magnetic separation, screening, fines, squeezing, loading of kiln, dewater, heating up in a steamer, heat up in a steamer dissolve kiln, the cooling pulverization process; The ironware that described magnetic separation operation obtains is through recycling; The plastics that the coarse fodder that described screening operation obtains obtains after artificial and water suspension method letter sorting operation are handled, cullet, non-ferrous metal are through recycling; Described thick material artificial and that water suspension method letter sorting operation obtains is sent into the loading of kiln of loading of kiln operation; The pressed liquor that described squeezing process obtains enters methane-generating pit and carries out fermentation process; Described cleaning fluid artificial and that water suspension method letter sorting operation obtains enters methane-generating pit and carries out fermentation process; The biogas that described pressed liquor, cleaning fluid produce in methane-generating pit is as dewatering, heat up in a steamer the heating raw of chemical industry preface; Described dehydration, heat up in a steamer the pyrolysis gas that produces in the chemical industry preface and handle through multilevel system.
It is Unareobic fermentation that the pressed liquor that obtains in the described squeezing process is handled the process of taking.
The described heating-up temperature t that heats up in a steamer in the chemical industry preface is: 180 ℃≤t≤220 ℃.
During processing, domestic waste is concentrated, carried out break process.Rubbish after the fragmentation is sent into magnetic separator and is carried out magnetic separation, absorbs ironware.The ironware of absorbing out is recycled.Rubbish after the fragmentation is after the magnetic separator magnetic separation, and rubbish enters screening machine and sieves under the drive of induction system.The coarse fodder that the screening operation obtains is told plastics, cullet, non-ferrous metal after artificial and water suspension method letter sorting operation are handled, and recycles.The fines that the screening operation obtains is sent into squeezer and is squeezed processing.Pressed liquor that squeezing process squeezes out and cleaning fluid enter methane-generating pit and carry out fermentation process, and the biogas of generation is as dewatering, heat up in a steamer the heating raw of chemical industry preface.The press residue that squeezing process squeezes out is sent into the loading of kiln of loading of kiln operation, enters dehydration, heats up in a steamer the chemical industry preface and handle.Can be used as the material of brick made from waste through the rubbish slag kiln discharge of heating up in a steamer, after pulverizing.
Advantage of the present invention is; Because be provided with magnetic separation, screening operation,, thus effectively useful thing is reclaimed; Because the coarse fodder that obtains of screening operation takes the method for artificial and aqueous suspension to sort, and has utilized the characteristic of water to handle, simultaneously regenerant is cleaned, thereby reduced the secondary pollution of regenerant, help the recycling of regenerant; Because pressed liquor, cleaning fluid be after fermentation process, the biogas of generation as dehydration, heat up in a steamer the heating raw of chemical industry preface, thereby made full use of resource, greatly reduce the cost of garbage disposal, reduced pollution simultaneously; Owing to dehydration, heat up in a steamer the pyrolysis gas that produces in the chemical industry preface, thereby significantly reduced banishing of pernicious gas through multistage circular treatment; Owing to take Unareobic fermentation that pressed liquor is handled, thereby reduced the cost of handling, improved the rate that of biogas; Because the rubbish slag after handling can be used as the material of brickmaking, thereby turns waste into wealth, help resource circulation and use; Because the process uniqueness, processing cost is low, pollutes for a short time, and dependable performance is so there is very big practical and popularizing value.
