Description
Technical field
The invention belongs to garbage reclamation reutilization technology field more particularly to a kind of recycling and reusing sides of house refuse
Method.
Background technique
House refuse refers in daily life or provides for daily life the solid waste generated in the activity of service
And law, administrative regulation provide the solid waste for being considered as house refuse, mainly include recyclable rubbish, garbage, nocuousness
Rubbish and Other Waste.Wherein, recyclable rubbish includes stationery, metal, plastics, glass etc., is recycled by integrated treatment,
Pollution can be reduced, resource is saved；Garbage includes the foodstuffs wastes such as leftovers leftovers, bone, dish green tops；Harmful Waste
Including refuse battery, waste daylight lamp tube, useless mercurial thermometer, Expired drug etc.；Other Waste includes in addition to above-mentioned a few class rubbish
Brick and tile ceramics, dregs, toilet waste paper etc. be difficult to the waste recycled.
China will realize the industrialization of domestic waste, recycling, minimizing and innoxious, must just receive in face of mixing
Collection, the content of recyclable materials and calorific value are low, msw water content and the high house refuse of biodegradable organic content.For
These problems, diversified technology are also applied and are given birth to, including combustion gas etc. is made in landfill, burning, compost and recycling.
The Chinese document of Publication No. CN101798531A discloses " refuse breaking and cracking treatment process and pyrolysis furnace ",
It is completed by following steps:（1）Rubbish coarse crushing；（2）Drying garbage；（3）Rubbish removes iron；（4）Rubbish second-time breakage；（5）Cracking
Furnace processing；（6）Gas-liquid separation；（7）Combustible gas reuse.A large amount of catalyst has been used in the cracking treatment process of the technique, and
The price of catalyst costly, so that garbage reclamation processing cost is excessively high, is unsuitable for large-scale application.
For this purpose, being attempted to for technical problem present in document disclosed above by garbage cracking treatment process
It improves, to reduce garbage reclamation processing cost, it is enable to promote and apply on a large scale.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of life refuse high temperature cracking treatment process method, this method
It can solve to exist in the prior art and used a large amount of catalyst in garbage cracking treatment process, and the price of catalyst is more
Valuableness, so that garbage reclamation processing cost is excessively high, the problem of being unsuitable for large-scale application.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is that：
It includes the following steps：
By by sieving, being crushed, dry, except the house refuse of iron is put into pyrolysis furnace, the pressure in the pyrolysis furnace is then controlled
In three phase point hereinafter, and controlling oxygen content in the pyrolysis furnace lower than 0.5%, under this condition by the temperature in pyrolysis furnace
550 DEG C~800 DEG C are heated to, and carries out cracking reaction at such a temperature.
In above-mentioned technical proposal, more specific technical solution be can also be：Before house refuse is put into pyrolysis furnace, first will
Quick-frozen to subzero 10 DEG C of the house refuse or less.
Further, it is described screening refer to will house refuse be sent into screening plant in remove heavy sand, soil and
Stone.
Further, described be crushed refers to that by granularity is crushed in the house refuse feeding pulverizer by screening be 1mm
~10mm.
Further, the drying, which refers to be sent into dryer by screening, broken house refuse, is dried to content
Water is 10% or less.
Further, described to be sent into magnetic separator and remove by screening, broken, drying house refuse except iron refers to
99.9% iron.
Due to the adoption of the above technical scheme, the present invention has the advantages that：
1. the present invention cracks the pressure and temperature in treatment process by control house refuse, so that in no addition cracking and catalyzing
In the case where agent, lytic effect will not be declined.
2. the present invention by the way that house refuse is first carried out quick-frozen Pintsch process again, not only reduction house refuse in it is useful at
Divide and go bad because of oxidation, the time that its cracking needs can also be shortened.
