Description
Technical field
The invention belongs to coal gas preparing technical fields, and in particular to a kind of method of gas burner oxygenation gas.
Background technology
Gas making at present mainly produces good semiwater gas as the unstripped gas of synthesis ammonia using fixed-bed intermittent formula regenerative process.
One of traditional fixed-bed intermittent gasification process cycle be divided into blowing, on blow, under blow, it is secondary on blow, blow off five stages.Tradition
Fixed-bed intermittent gasification process feature：It is technology maturation, easy to operate；Active ingredient is higher in coal gas, above blows effective gas (CO+H2)
Average 85%, under blow effective gas average 96%；It is wide to be applicable in coal scope；Small investment；Aspect of blowing efficiency is low, and single stove gas production is low, by
In into the oxygen sources needed for gasification furnace burning, in air, oxygen concentration is low (21%), and the unit interval releases with charcoal reaction
Heat is few, can only improve gasification layer temperature by extending blow-time, cause aspect of blowing efficiency low, and capacity usage ratio is low, single stove production
Tolerance is low；Environmental pollution is big, containing dust, carbon dioxide and sulfide in the blowing-out gas of generation, is discharged into air and environment is caused
Pollution.
Therefore, in recent years mostly using oxygen-enriched continuous gasification flow, the characteristics of oxygen-enriched continuous gasification process：Technology maturation, fortune
Row is unstable (being directed to existing inferior raw material)；Mating air separation unit is needed, one-time investment is big, and industrialized unit is not yet popularized；It is right
Coal is selectively strong；Carbon dioxide is high in coal gas, and methane content is high, available gas 65-72%；Single stove gas production is high, between being about
1 times of having a short break or more；It is always continuous upper blowing gas, no blowing-out gas is vented, and environmental pollution is small.
Therefore, at present mostly using fixed-bed intermittent gasification process, fixed-bed intermittent gasification process process is simple, using sky
Gas, steam gasification agent enter stove gas stage by stage, belong to accumulation of heat gas making method, and temperature difference amplitude is big, and gas overall quality is good, especially under
It blows the stage, makings is more preferable than above blowing, and the current energy consumption of the technique remains high, and main cause is blowing heating using air, thermal effect
Rate is poor, heat loss is big.Oxygen-rich gasification above blows gas, the self-heating gas making method that heat supply and gas processed carry out together, temperature difference width to be continuous
Spend small, gas production is big, and environmental pollution is small, but carbon dioxide, methane content are high in coal gas, and the continuous and steady operation time is short, in gas
Change easy slagging caking during inferior raw material, timing blowing out is needed manually to take off block processing.
The content of the invention
The present invention is in order to solve the above technical problems, provide a kind of method of gas burner oxygenation gas.
It is realized particular by following technical scheme：
A kind of method of gas burner oxygenation gas, by the oxygen concentration entered in stove air of traditional fixed-bed intermittent words said in a fit of rage technique
It is increased to 24-28%.
Further, one of method cycle include recycling, on blow, under blow section, it is secondary on blow four steps.Wherein
Under blow time 52s, above blow the time for 23-25s.
Further, the method is the oxygen in self-control oxygen post and air pressurization mixing in the future, passes through self-adjusting valve and air blast
Machine is delivered to gas burner, oxygenation air and low-pressure steam after concentration oxygenation air needed for being made into, and interval or is mixed into gas burner,
Respectively by recycling, on blow, under blow section, it is secondary on blow four steps, wherein be recovered as by blowing-out gas all recycling entered cabinet.
Further, the oxygen in future self-control oxygen post and air pressurization mixing, are to control pressure in 34-
36kPa。
Further, the oxygen in future self-control oxygen post and air pressurization mixing, the concentration of mixed oxygen exist
70%.
Advantageous effect, the present invention increase O in gas-making process2Volume fraction, on the one hand can improve O2Diffusion promotes
On the other hand power can make up the reduction of temperature degree processed, improve steam decomposition rate, increase CO, H2Equilibrium concentration, to improve aerogenesis
Amount, accordingly also reduces blow-time.Meanwhile also to avoid peroxide steam and oxygen-enriched proportioning appropriate in gas-making process, it can obtain
Higher steam decomposition rate.
Oxygenation intermittent gasification syngas for synthetic ammonia technology of the present invention, realization optimize semiwater gas quality and add partly
The yield of water-gas reduces the loss of unnecessary effective carbon in blowing and gas-making process.The consumption of feed coal is greatly lowered,
Reduce CO2The emission reduction of greenhouse gas and sulfide gas.
