Description
Technical field
The invention belongs to environmental conservation and technical field of heat treatment, it is related to a kind of steam heating device and its place
Reason method and purposes, more particularly, to a kind of occur the annealing device of constant-pressure and high-temperature steam and its processing method and
Purposes.
Background technology
With China's rapid development of economy, China is in many necks such as soil, water resource and atmospheric environment
Domain encounters the activated sludge of serious problem of environmental pollution, the wherein disposal of toxic refuse and water process generation
Process all have become as important technological difficulties and significant problem urgently to be resolved hurrily.
At present, China is not almost substantially in progress in the technical research of refuse classification and sorting field, actual feelings
Condition is similar with the situation before Japanese 50 years: waste plastics, rubbish from cooking, paper, glass and metal or even high poison
The various rubbish such as battery mix and put, bring huge difficult treatment to waste incineration station.The gold being mixed in rubbish
Belong to and glass is it is easy to melt and damage incinerator in incinerator；Additionally, it is chloride higher
Plastics easily produce the hypertoxic product such as two English in burning process and cause the pollution of air.Because rubbish burns
Burning is difficult to efficiently and is rapidly performed by, and there is larger place where the garage is piled up in current China near large- and-medium size cities,
The source of the mixed rubbish put not still foul gass, its leachates also tends to (mainly come containing hypertoxic heavy metal
From battery), huge threat is all created to neighbouring subsoil water and surface water.Therefore, for being difficult to burn
High poison rubbish, be badly in need of the process meanses that a kind of fast and harmless is processed.
Additionally, current China is with the presence of the production technology that can produce the difficult garbage of high poison in a large number, it is produced
Raw garbage is often stacked, shelves or even is privately buried steathily by enterprise because treatment cost is too high, and this all gives
Natural environment causes huge threat.Meanwhile, the annual generation of the bioanalysises water treatment facilities of China is substantial amounts of
Activated sludge, the still more difficult burning after dewatering of these mud, so be badly in need of a kind of method can enter to it
Row sterilizing, carbonization and deodorizing process.
For the process of these materials above-mentioned, external and domestic research worker was once reported high using high temperature
The steam of pressure provides a kind of rubbish being cleared up the method with innoxious governance, patent cn 20213179u
Processing system, it includes steam boiler, steam accumulator and steam reaction kettle；Steam boiler is communicated to steam
Thermophore, steam accumulator is communicated to steam reaction kettle group；It processes rubbish using high temperature and high pressure steam,
And screening and separating is carried out to the rubbish producing.At high temperature under high pressure, water vapour can show extremely strong oxidation,
The ability of decomposition and carbonization is it might even be possible to effectively degrade intractable for Polychlorinated biphenyls etc. noxious substance.But
Because the steam power consumption of High Temperature High Pressure is very big, and the security requirement to equipment is too high, therefore, it is difficult to big advise
Mould is implemented.On September 30th, 2004, Ono Tatsumi of green grass or young crops carpenter's industry Co., Ltd. of Japan discloses a kind of often use
Carrying out the patented technology (cn 100362080c) of heat treatment, this technology is using special electricity to super pressure-high temperature steam
Heating means, normal pressure water vapour are warming up to 1200 DEG C even 2000 DEG C of high temperature, for carrying out height to material
Warm steam-heated procedure, the method uses high compressed steam due to avoiding, and the therefore requirement to equipment substantially reduces,
The material having extremely strong corrosivity, therefore firing equipment and Equipment for Heating Processing yet with high-temperature vapour is very
Fastidious, additionally, the three of its zone heating kinds of heater technical difficulty are higher, general heater manufacturer is difficult
Realize.

Flame burning improves its temperature, then makes atmospheric steam pass through accumulation of heat porous ceramicss, and is grasped by multiple intervals
Mutual switching cooperation between the heat-accumulation combustor made, obtains the steam of high-temperature pressure, then material is carried out at heat
Reason.Which obviate special heater, high-temperature pressure steam can be obtained by the natural gas that burns, and not
There is the danger of blast, the requirement to device fabrication is relatively low；Produced gas can be used for poisonous
The harmlessness disposing being harmful to difficult pollutant is it is also possible to carry out at carbonization taste removal to materials such as activated sludge
