Description
Technical field
The utility model belongs to field of chemical equipment, discloses a kind of new conversion stove of coke-stove gas producing synthesis gas,
Synthesis gas can be widely used for the chemical products such as production methanol, liquefied ammonia, ethylene glycol.
Background technology
Coke-stove gas is that one kind contains CH4、C2H6、H2、CO、CO2、N2Deng the mixed gas of composition, wherein CH4Deng gaseous hydrocarbon
Content is up to 25~28%.Methane hydro carbons in oven gas must be converted into CO+H by reburner2, synthesis gas could be turned into.
The gaseous mixture of traditional reburner, oven gas and water vapour enters at the top of burner, and oxygen passes through from burner side
Nonmetal burner containing high purity aluminium oxide with some apertures is sprayed, and the good oven gas water vapour of the mixture got off with top is mixed
Close, downwardly together into trumpet type combustion chamber, gas releases heat in combustion chambers burn, enter back into catalyst layer and carry out methane
Conversion reaction, conversion gas of the generation containing hydrogen and carbon monoxide is methyl methanol syngas, is sent out from conversion furnace bottom.
Because nonmetal burner is that multiple apertures through annular array spray oxygen, spouting velocity is too fast all to be made instead slowly excessively
The unordered disturbance of combustion flame answered.In addition, wearability and intensity are poor at high temperature for nonmetal burner, and it can not be cooled down,
So it is fragile in production, often change.
Utility model content
The utility model overcomes the shortcomings of prior art presence, and there is provided a kind of gas mixing is uniform, burning is abundant, using the longevity
Order the new conversion stove of long coke-stove gas producing synthesis gas.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of coke-stove gas produces synthesis
The new conversion stove of gas, including housing, the inner walls are provided with fire resisting and pour material liner；The housing exterior walls are wrapped with
Water leg；Its lower end is provided with reformed gas outlet；The housing sidewall is provided with the thermometer for detecting in-furnace temperature；Institute
State housing upper end and heat-resistance stainless steel burner, the housing are setTopSide wall sets raw material air inlet, and the burner outer wall is set
Water cooling chuck；The burner lower end sets radial bar shaped distributor.
Using this programme, a small amount of water vapour is incorporated in oxygen-containing 99.6% oxygen, band water cooling is passed through from reburner top
The heat-resistance stainless steel burner of chuck enters reburner, enters combustion chamber by distributor together with after unstrpped gas mixing；Make gas
Body sufficiently burns in combustion chamber, it is to avoid hot-spot makes temperature field in combustion chamber and airflow field more rational.Wherein, oxygen
Vapour content in gas is 10% or so of amount of oxygen, and this water vapor pressure need to be higher than conversion furnace pressure, and prevent burner can
Combustion gas body sets off an explosion through burner backflow.
Further, the raw material air inlet includes the air inlet pipe that two horizontal symmetricals are set；In two air inlet pipe
Heart absolute altitude, which is located at, to be stretched at the golden section point of the burner length vertically downward in burner.Using this programme, coke-stove gas and
After water vapour is mixed by a certain percentage, enter respectively through two pipelines from the side of burner, equably can get off with top
Oxygen mix.
In combustion chamber, part H in coke-stove gas2And CH4With O2Carry out combustion reaction.
H2+½O2→H2O
CH4+2O2→CO2+2H2O
Reaction temperature may be up to 1250 DEG C or so, and then gas enters Raney nickel layer 4, carry out turn of methane in oven gas
Change reaction.
CH4+ H2O→CO+3H2
CH4+ CO2→2CO+2H2
Final reaction is determined by CO transformationreation：
CO+H2O→CO2+H2
The conversion gas containing carbon monoxide and hydrogen after conversion, i.e. methyl methanol syngas are sent out from conversion furnace bottom 11.
The utility model has following beneficial effect compared with prior art：
1st, by setting distributor, gas sufficiently burns in combustion chamber, it is to avoid hot-spot makes the temperature in combustion chamber
Spend field and airflow field is more rational.2nd, the air inlet pipe that two horizontal symmetricals are set, the oxygen that equably can get off with top is mixed
Close.
