Description
Technical field
The present invention relates to the technical field of incinerator apptss, in particular to a kind of incinerator apptss.
Background technology
Hazardous waste refers to be included in《National Hazard waste register》Or according to the hazardous waste judging standard of national regulation
The waste with hazard property assert with discrimination method.Hazardous waste divides 47 major classes kind more than totally 600, and species is more, complicated component,
With toxicity, corrosivity, inflammable and explosive property, chemical reactivity, infectiousness, radioactivity etc., it, which pollutes, has potentiality and delayed
Property, it is one of emphasis and difficulties of global environmental protection.
, should be according to its classification, composition composition and its physics, chemistry etc. in processing because hazardous waste has above-mentioned characteristic
Characteristic, carries out different disposal.The processing method of disposal in the world to hazardous waste has at present：Burning, landfill, resource reclaim
(reuse), safe storage, physical chemistry processing etc..
Burn as a kind of processing method of disposal, it is adaptable to those can not recycle, recycle or security landfill waste.
Incineration temperature is very high, is a kind of thermal oxidation process, wherein hazardous waste and oxygen reaction in air, generates gas and is difficult to fire again
The solid residue of burning.Produced gas needs to discharge after purifying, and solid residue must carry out security landfill disposal.Hazardous waste passes through
After burning disposal, most organic is transformed into inorganic matter, and Waste volume reduces 85%~90%.Greatly reduce and finally fill out
The amount of burying and expense, eliminate or mitigate toxicity and infectiousness of waste etc..Having after burning disposal makes waste reach stabilisation, safety
Change, the advantage of minimizing.
At present, the domestic burning disposal to hazardous waste uses rotary kiln incinerator, liquid injection formula incinerator, fluid bed
The type of furnaces such as incinerator, fixed bed incinerator, multilayer incinerator and cement kiln, these incineration technologies are using downflow type (i.e. cigarette
Air-flow is consistent to the flow direction with waste in incinerator) peroxide burning.In actual motion, it is immature to there is handling process,
Complete and fault rate is not high for coordinative composition of equipments, and Absorption of Imported Techniques and equipment are not in place, the problems such as operating lack of standardization, shows as burning temperature
Degree is low, and hazardous waste is unable to complete sterilizing, decomposes and detoxify, and fume emission is not up to standard, and severe operational environment causes new dirt
Dye, while auxiliary fuel consumption is big.
Burning of the burning of hazardous waste than general house refuse requires tightened up.Incinerator is the core of whole incineration technology
Center portion point, it decides the processing task of hommization operation, innoxious degree and the follow-up tail gas in dangerous waste incineration workshop.Danger
The factors affect such as oxygen content of the dangerous waste in residence time, the pyrolysis of the rotary kiln degree of hazardous waste processing.Due to
Toxic and harmful gas can be produced during trash burning, and some toxic and harmful gas can flow into air by feeding-passage, cause
The pollution of air.
The content of the invention
It is unstable to solve trash burning of the prior art it is a primary object of the present invention to provide a kind of incinerator apptss
The problem of fixed, high energy consumption, discharge not up to standard.
To achieve these goals, according to an aspect of the invention, there is provided a kind of incinerator apptss, including：Burn
Stove unit, incinerator unit includes the gas being passed through in feeding structure, rotary kiln and the dual firing chamber connected with rotary kiln, rotary kiln
Amount, which is less than in preset value, dual firing chamber, is passed through gas flow higher than preset value, and feeding structure includes charging housing, the first valve and second
Valve, the first valve and the second valve are respectively positioned in charging housing, and the first valve is located at the upstream of the second valve；Fume treatment list
Member, fume treatment unit is connected to handle the flue gas in incinerator unit with incinerator unit.
Further, rotary kiln also includes shell and liner, and the two-end thickness of liner is more than the thickness of center section liner.
Further, interior lining is provided with the flight structure for the inner surface for protruding from liner.
Further, rotary kiln includes rotary kiln main body, kiln head cover and the kiln hood being connected with each other, kiln head cover and rotary kiln
Having between main body has the second sealing device between first sealing device and/or kiln hood and rotary kiln main body.
Further, feeding structure is arranged on the first end of rotary kiln, and feeding structure is on dustpan shape structure, feeding structure
It is provided with water-cooling structure.
Further, incinerator unit also includes deslagging device, and deslagging device is arranged on the second end of rotary kiln, dress of slagging tap
Put including sealing structure for water.
Further, fume treatment unit includes flash cold column, scrubbing tower, waste heat recovery structure and chimney, and scrubbing tower is with burning
Burn stove unit to be connected, flash cold column is arranged between scrubbing tower and incinerator unit, and chimney is arranged on chimney and is arranged on scrubbing tower
Downstream, waste heat recovery structure be arranged in chimney with the flue gas heat exchange in chimney.
Further, waste heat recovery structure includes heat exchanger, pipeline and the conveying equipment for fluid substances being arranged on pipeline, heat exchange
Device is arranged in chimney, and heat exchanger is connected with pipeline.
Further, fume treatment unit also includes extracting tower, and extracting tower is arranged between flash cold column and scrubbing tower, depickling
Tower also includes extracting tower main body, activated carbon warehouse and pulverized limestone warehouse, activated carbon warehouse and pulverized limestone warehouse and extracting tower main body
It is connected.
Further, fume treatment unit also includes dust arrester, and dust arrester is arranged between extracting tower and scrubbing tower.
Apply the technical scheme of the present invention, when combustion waste, first, the first valve and the second valve closed,
Waste is added into feeding structure again, the valve of upstream is then opened, met into the material between the first valve and the second valve
It is required that after close the valve of upstream, then open the valve in downstream, the valve in downstream is closed in charging after finishing, then pass through pusher portion will
Material is pushed into rotary kiln, because the gas flow being passed through in rotary kiln is not enough, so that hazardous waste is sent out under anaerobic conditions
Raw pyrolytic reaction, is decomposed into combustible.Combustible after decomposition enters dual firing chamber, due to having sufficient oxygen can in dual firing chamber
So that the analyte burning of hazardous waste, said structure causes the more thorough of hazardous waste decomposition, the hazardous waste after decomposition
Burning is more abundant.Cause the flue gas of burning will not be flowed into by feeding-passage big by the cooperation of the first valve and the second valve
Gas, the air that can also so efficiently control into rotary kiln so greatly reduces the pollution to air.The present invention's
The problem of technical scheme efficiently solves unstable trash burning of the prior art, high energy consumption, discharges not up to standard.
