Detailed description of the invention
The present invention is further described by way of illustration with reference to attached drawing, and the attached drawing is shown from side and with section according to this
DC arc plasma gasifier described in one form of invention.
Specific embodiment
In carrying out the present invention, using the structure for being similar to multi-electrode DC open arc furnace.It may be implemented using the concept bigger
Vaporization ability.As noted, the gasification based on plasma does not need oxygen, and undesirable gas separative unit.Row
Except the estimated capital cost that will reduce equipment of these features.
In gasification, process temperature is the major parameter for acting on dynamics and carbon conversion.Process temperature depends on
The property of gasification structure and for the purpose of realizing maximum and effective energy transmission by plasma arc by radiation and convection current means
Design factor.
Attached drawing shows DC arc gasifier 10 according to the present invention comprising bottom container 12 and upper container
14, upper container 14 is operated as entrainment fluidization tower 16.
Bottom container 12 includes the clinker contained structure 20 with lid 22.Multiple electrodes 24,26 etc. pass through in lid
Each port.Sealing element 28 is used to seal each interface between lid 22 and each electrode 24,26 etc..
Structure 20 has scum hole 30 at suitable position.
Appropriate location of the slurry 36 of powdered coal 38 and dry saturated steam 40 on the side of column 16 is introduced into entrained flow
In column 16.As described below, slurry 36 can also introduce contained structure via the arc plumes (not shown) of 22 lower section of lid
In 20.Feed entrance point should be appropriately carried out to optimize gasification efficiency.Two kinds of feeding manners can use.
At lower port 44, process residues object (not shown) is discharged into contained structure by lid 22 by entrainment fluidization tower 16
In 20.
Upper container 14 is operated as entrained flow gasifier.Powdered coal 38 and dry saturated steam 40 are in container 14 with simultaneously
Stream mode contacts.Gasification reaction occurs in fine grained cloud.Because producing High Operating Temperature by plasma arc in container 14,
Therefore inferior grade coal and discarded coal are suitable for such gasification.High temperature and effective pressure in container 14
The ratio and steam characteristics of (prevailing pressure), residence time, steam and coal are selections to realize higher original
Expect the parameter of output.Due to above-mentioned condition, tar and methane (volatile) are not present in product gas.
It can be flowed into entrained flow gasifier 16 by the gas generated in bottom container 12 with oxygen fraction burning
The additional heating of row.This helps to reduce the power consumption in entrained flow gasifier 16.
Coal/steam slurry 36 is introduced into the upper area inside structure 20.However, it is possible to which slurry 36 is introduced into
Lower area inside structure 20, or it is introduced into upper area and lower area.Optionally, it is arranged in the lower part of entrainment fluidization tower 16
It puts at port 44 using nozzle (not shown), coal/steam slurry 36 is directed to the inside of structure 20.Alternatively or additionally
Coal/steam slurry 36 is fed to the inside of structure 20 as dotted line 50 is hypothetically pointed out by ground by electrode 24,26 etc..
For this purpose, each electrode is formed with extended tubulus 52, which is lined with one layer of protection materials, such as ceramic jacket
Pipe, to steam inertia and resistance to heat-shock.When using the device, therefore slurry 36 is fed to structure 20 with open arc plume
Inside.
Electrode 24,26 with open arc configuration show, i.e., lower port not contact accumulation in the lower area inside structure 20
Slag 56.High temperature reducing conditions are established by open arc in the top of slag 56 within the container 12.However, it is possible to by electrode 24,
26 lower port immerses in slag 56, so that coal gasifiers are operated as the submerged arc reactor based on clinker.Mixing is general
Thought be it is possible, that is, use submerged arc and open arc plasma heating gasifier.
It is important to control various processes parameter, during the operation of gasifier 10 to realize efficient operation.This
A little parameters include being supplied to the size of the voltage and current of electrode and in the presence of steam or synthesis gas or in various ratios
The power consumption and stability of electric arc in the case where steam and synthesis gas inside container 12.
During the operation of gasifier 10, the temperature inside upper container 14 should remain above 600 DEG C, have to realize
The Coal Gasification of effect.Higher temperature is preferably as they improve gasification rate.Energy packet in upper container 14
Include the enthalpy for flowing through its gaseous product.
The operation of metallurgical base gasifier 10 in bottom container 12 is similar to the operation of submerged arc smelting furnace.Most of arc energy
Amount passes through convection current to molten slag bath 56.Powdered coal 38 and dry saturated steam 40 are injected into the one or more electricity of 56 top of pond
In arc plume.It is expected that limiting the influence of electrode corrosion using dry saturated steam and helping to stablize electric arc.In molten bath Coal Gasification
In method, the heat transmitting to reaction zone and the exposure level between coal and steam may limit dynamics and reactor production
Amount.In this case, the upper container 14 operated as entrained flow gasifier 16 provides additional output.Therefore, under
Portion's container 12 is used to prepare synthesis gas, and the synthesis gas is burned to provide energy for the Coal Gasification in entrained flow gasifier 16
Amount.
Gasification carries out in steam plasma body.The behavior of hydrone and especially hydrogen molecule is important, because
This behavior can determine that plasma forms.Steam plasma body needs more energy than air or carbon monoxide plasma
Amount is to dissociate.Net effect is that steam plasma body has resistivity more higher than air or carbon monoxide plasma.Therefore, will
Steam, which introduces reaction zone, can cause the significant change of resistivity.But this must be will not generate unfavorable shadow to arc stability
Loud mode carries out.Since dry saturated steam environment brings higher arc resistance, to establish longer electric arc, therefore electrode needs
Want higher voltage.
Method product (i.e. synthesis gas) is extracted out via port 60 from the upper area of bottom container 12.
Compared with existing incinerator or plasmatorch gasification reactor design, the present invention has the advantages that several.First
Benefit is not need individual equipment come the raw material for preparing pure oxygen as reactor, thereby saves capital and operating cost.The
Two have an advantage that plasma arc operates under the excessive temperature of at least 10000 DEG C of the order of magnitude, to generate quality improvement
Synthesis gas.Third, metallurgical DC furnace use up to 80 MWs much higher in operation power more accessible than plasmatorch reactor
Operation power under by verifying and effective technology.This means that the DC gasifier based on technology relevant to metallurgical DC furnace is pre-
Phase can generate economies of scale.
