Abstract
The invention relates to the technical field of organic waste treatment equipment, in particular to a method and a device for carbonizing production wastewater of printing and dyeing intermediates through superheated steam. The method comprises steps as follows: production wastewater of the printing and dyeing intermediates such as H-acid, T-acid and para-ester is subjected to distillation and concentration or low-temperature desalination and then is subjected to spray drying, dry powder waste is formed, the waste is put into a superheated steam carbonizing furnace for continuous anaerobic carbonization, and the superheated steam at the temperature of 350-850 DEG C is adopted for carbonization. According to the method, the uniformity of the carbonization is guaranteed, the COD (chemical oxygen demand) content is reduced to 500 mg/kg or lower, and recycling of sodium sulfate and sodium chloride is guaranteed. With the popularization of the technology, the bottleneck of an environmentally sound technology restricting production of H-acid, T-acid and para-ester is solved, so that large-scale production of the printing and dyeing intermediates is promoted rapidly.
Description
Technical field
The present invention relates to intermediate processing method technical field of printing and dyeing, it is a kind of overheated to especially relate to
Steam carbonization printing and dyeing intermediate produces the method and device of waste water.
Background technology
H-acid, T acid, para-ester are the dyestuff intermediates of dyeing.At present, chemical plant exists
During producing these three intermediate, the production waste water of a large amount of high pollution can be produced.Produce waste water
Conventional processing method has a variety of: ozone-hydrogen peroxide oxidation pre-treatment, emulsion liquid membrane
Process, the methods such as wet air oxidation processes, complexing abstraction.Prior art provides one
Kind of color-forming intermediate H acids produces the processing method of waste water, it merely disclose how H-acid (and
Not mentioned T acid, para-ester) produce the method how waste water becomes solid waste, carbonization is simply
Simply carry 300 DEG C～800 DEG C, be not mentioned to the core technology superheated steam of carbonization, also
And not mentioned concrete device and concrete carbonization method.
At present, the technology of carbonization only refers to use simple external-heat or internal heat type hot-air carbonization skill
Art.For external-heat carbonizing plant and method, it is to utilize biomass fuel heating furnace, then passes
Hot carbide furnace outer wall, so that organic carbon in stove.Or use shell jacketed fixed body
Heater, heat with heat conduction media such as liquid salt, from shell heat transfer carbide furnace in material.
The method common drawback is to be all that heat transfer is slow, and energy consumption is high, and carbonization is uneven, and equipment seals and heat
Media leak into fatal problem.For internal heat type carbonizing plant, reach carbonization by adding hot-air
Temperature required, send in carbide furnace, the direct contacting material of hot-air, but hot-air is rich in oxygen,
Such as producing the sodium sulfate in garbage with H-acid, T acid, para-ester, sodium chloride is easy to combustion
Burn melting, carbonization weak effect, and easily etching apparatus, damage equipment.
Therefore, use any of the above method, H-acid of all can not significantly degrading, T acid, para-ester
Produce below the COD to 500mg/kg of Coal Gas Washing Cycling Water, contained naphthalene in three of the above material,
The Organic substance of aniline series can not be uniform carburized, causes sulphuric acid contained in garbage after carbonization
Sodium, sodium chloride can not sufficiently be recycled, and cause the waste of resource.
Summary of the invention
It is an object of the invention to provide carbonized by means of superheated steam printing and dyeing intermediate and produce the side of waste water
Method, to solve the wasting of resources present in prior art, carbonization weak effect and equipment dependability
The highest technical problem.
For solving above-mentioned technical problem, the present invention provides a kind of carbonized by means of superheated steam printing and dyeing intermediate

Recycle；
S4, by carbonisation produce waste gas remove through the first cyclone dust extractor, the second whirlwind successively
Dirt device is fed through in deodorization stove, and the temperature of deodorization stove is set as 850-1200 DEG C, and to useless
The fuel gas mixed in gas carries out burning for the first time；
S5, will be processed by deodorization stove after waste gas be fed through in superheated steam generator and carry out second
Secondary burning, is set as 850 DEG C by the temperature of superheated steam generator；
S6, will be processed by superheated steam generator after waste gas be fed through through the 3rd cyclone dust extractor
Conduction-oil warming device, conduction oil is heated by the waste heat utilizing waste gas to carry；
S7, will be processed by conduction-oil warming device after waste gas send into tail gas eventually by waste discharge blower fan
End processing system carries out final clean process, and by chimney high altitude discharge.
