Description
Technical field
The present invention relates to a kind of for carrying out the reactor of entrained flow gasification to carbon-containing fuel, and the reactor is anti-with one
Answer room and the cooling chamber being connected with the reaction chamber within a pressure-bearing reactor wall.
Background technique
The entrained flow gasification of this carbon-containing fuel is used for the generation rich in hydrogen and CO gas, these gas conducts
Synthetic gas, reducibility gas, town gas or the gas for energy purpose are applied.
When gas generates, in 1200 DEG C to 1800 DEG C of temperature and until under 80 bars of pressure, in oxygen and vapor
Or the coal gasification of the lower ash shape of carbon dioxide participation is realized in showy mist (Flugwolke) with flame reaction, wherein in addition to
Desired thick gas, there are also the mineral residues of melt liquid to occur in the form of slag particle.The gasification process of same principle is answered
For the gasification (tar, Residual oil) of liquid fuel, the suspended matter of liquid and solid fuel or the gasification for the biomass dried.
It is conclusive in the air-current bed gasification process of high pressure and high temperature to be, gasification in the reaction chamber steadily into
Row.This also includes that the gasification reaction body is carried out in this way, enables the melt liquid slag particle interference-free from the reaction chamber
It is discharged in the cooling chamber being arranged in below the reaction chamber or quenching chamber, wherein the melt liquid slag particle is from mineral clout
It generates and is deposited at the reaction chamber wall in the flame region of a gasification combustor in coal particle oxidation process.For this purpose, should
The formation funnel-shaped on the direction of a central slag outlet opening of the bottom plate of reaction chamber.
Still in the gas flow remaining melt liquid slag particle usually in the cooling chamber of the gas-flow reactors by means of water spray
Or the guidance for being loaded with the thick gas of slag by a water-bath is cooled to fusing point hereinafter, and as particle from the reactor
In by suspend in water in a manner of send out.
The reactor elements are subjected to strong abrasion in the region that slag is discharged.These reactor elements are melted liquid slag
Stream corrode, while heat corrosive reaction gas led into from the reaction chamber by the slag outlet opening be located next to it is cold
But in room, and extraly, the central floor panel region between reaction chamber and cooling chamber, which is exposed to, loads moist cooling
The heat affecting of room and atmosphere influence.It therefore should be to require corrosion most strong mill with the central floor panel region of slag outlet opening
One of component is damaged, the wear condition of these wearing terrains codetermines the runing time of the reactor.
The runing time (" running time ") that can be used for gasifying has huge shadow to the economy of coal gasification reactor
It rings.Caused by each process interrupt as caused by the maintenance of unstable gasification parameter or the part of appliance of abrasion the result is that：
Due to the high starting expended related to this and stopping process and installation and disassembly, the gasified reverse in compression resistance formed
It answers and generates high expense and long downtime at device.Central floor panel and the slag between reaction chamber and cooling chamber are discharged
The anti abrasive design of device and for simplify when repair situation at the slag discharger installation and removal consuming
Measure makes very important contribution to maintenance cost is reduced.
A kind of for making the reactor of coal dust gasification under stress, the reaction has been described in DD-PS 1 19 266
Tube wall construction restriction that the reaction chamber of device is loaded by a water, being protected by the pressing block (Stampfmasse) of one layer of fire resisting.
In order to be discharged to liquid slag in particulate elements (Granulierteil), a center is provided in the bottom plate of the reaction chamber
Opening, the profile of the opening has the tube wall construction of refractory coating to constitute by correspondingly design.
Since the material of the high quality of the pursuit wear resistance must be used, in DD-PS 1 19 266, slag discharge
The embodiment of opening is at high cost, and can only conditionally be suitable for through this due to higher heat load with dynamic load
The thick gas of heat and slag melt are discharged funnelform bottom plate opening jointly.
Due to directly being contacted with slag, after one section of longer runing time, it is in the high wear of slag discharge body
Inevitably, so should at least reduce the consuming of the slag discharge body for replacing the abrasion to the greatest extent.After mounting under state
Maintenance or the slag discharge body it is simple, quick disassembly and installation be advantageous thus.
Therefore slag discharge body has partly been configured as with heat and flux shielding coating and has twined in modern reactor
Around cooling water pipeline cooling screen replaceable isolated bottom plate part.
However one of these known solutions the disadvantage is that：The slag is arranged in the structural configuration of the central floor panel
Body simple replaceability after longer runing time considers very little out.
According to the prior art, slag discharger securely or with it is higher consuming be removably fitted into it is so-called " support
On plate " (central floor panel), which separates the reaction chamber with cooling chamber.
When a non-exchange slag discharger must be replaced jointly with the support plate, then for example according to DE 10
Described in 202,010 015 889 U1 of 2006 031 816 A1, DE 20 2,008 009 249 U1 and DE, these support plates
One of known embodiment the disadvantage is that, these support plates require the reception circle of a forging, which must quilt
It is welded in the set section (Mantelschuss) of the pressure-bearing reactor wall, and the reactor wall is necessary after being packed into the reception circle
Carry out a subsequent, expensive heat treatment.
It is with another related disadvantage of structural configuration known to the slag discharging area：Adjuster is discharged in slag
(Schlackeablauftrichter) nonventilated cavity or dead space are usually present around, the erosion from the reaction chamber
Property gas and the moisture from the cooling chamber may collect in these cavitys or dead space, and cause at the slag discharger
Quick high corrosion and time-consuming maintenance.
Reactor configurations according to 10 2,006 031 816 A1 of DE are one examples.
Summary of the invention
Therefore general object of the present invention is, a kind of for central floor panel from providing the shortcomings that the prior art
Structural solution, the solution improve the effective run time of entrained flow gasifiers, and mode is to reduce in centre
Disassembly and installation when corrosion wear in baseplate zone and maintenance at the slag discharger expends.
In the frame of the solution of suggestion, the target is real by the collective effect of the structural means of multiple complementations
It is existing.In order to efficiently reduce abrasion at the central floor panel, which is assembled by multiple element, multiple element gapless
Ground is connected with each other and connect with slag discharge body, forms the central floor panel so that being discharged between body and the reactor wall in the slag
An air seal, the downside of the gas compartment that limits the cooling chamber, downside protection this be used for the centre of reactor wall
Space is not influenced by the corrosive gas from cooling chamber.
In order to realize the protection of pressure balance and the corrosive gas for entrance, between these elements of the central floor panel
Cavity be connected to each other, connect with an inert gas purge device and the gas with the cooling chamber by pressure equalisation passage
