Abstract
A reformer for coke-oven gas pertaining to chemical process equipment is used for the conversion of CH4 in the coke-oven gas. The reformer of the prior art has the shortages that after the rich oxygen or pure oxygen enters an oxygen distributor, the anti-heat liner is blown into small grains to block the distributing hole and cause the safe hidden trouble, the service life of an activator is short, a gas collector can not dredge, etc. The utility model is additionally provided with a layer corundum liner out of the original oxygen distributor and overcomes the shortages, thus making the combustion distribution uniform, avoiding the situations of deflection burning and scorification, avoiding that the flame is directly contacted with the activator and is burned in a bed layer of the activator, and obviously improving the service life of the conversion activator. A conical top on top of the gas collector is changed into a moveable flat cover, which is convenient for the examining and repairing operation of the reformer. The utility model has the advantages of safe and reliable application, long service life, and convenient maintenance operation.
Description
Technical field:
The utility model belongs to chemical process equipment, is used for coke(oven)gas CH
4Conversion, the gaseous fraction after the conversion can be used for ammonia synthesizing industry and synthesizing methanol device.
Background technology:
Converter is the visual plant in the chemical plant installationss such as coke(oven)gas synthetic ammonia or synthesizing methanol, in synthesizing methanol, be preheating to from the coke(oven)gas of preheating oven and enter the converter burner about 660 ℃ and in burner, burn with oxygen enrichment or pure oxygen through preheating, gas after the burning is heated to more than 1500 ℃, enter in the conversion catalyst of splendid attire in the converter body of heater and carry out conversion reaction, collect the back through the reforming gas of conversion reaction by the furnace bottom gas collector and from the furnace bottom threeway, discharge converter, remove synthetic ammonia or methyl alcohol, CH in the reforming gas of this moment
4Content is less than 0.5%.
The existing converter that is used for the coke(oven)gas conversion, coke(oven)gas through preheating is imported by the top, oxygen enrichment or pure oxygen through preheating enter the oxygen divider by oxygen intake, dispensing orifice on the oxygen divider, enter in the stove carry out combustion reactions with coke(oven)gas after, enter beds and carry out conversion reaction, entering behind the gas collector derives outside the stove again.In the process that reality is used, find following situation: after one, oxygen enrichment or pure oxygen enter the oxygen divider, gas speed is higher, aggregate in the local heat-resistant lining is blown out granule, stopped up the dispensing orifice on the oxygen divider, cause inclined to one side burning, appearance oxygen divider softens or burns and melts, and brings great potential safety hazard; Two, hot spots and beds distance is too small, and flame has the phenomenon of burning catalyzer, and catalyzer is shorter work-ing life; Three, original gas collector top is a pyramidal structure, is welded to connect with cylindrical shell, can't dredge in the use.
The utility model content:
The purpose of this utility model is to overcome the shortcoming of original converter, designs a kind of novel converter that is used for coke(oven)gas, and it has advantages such as safe and reliable, that the life-span is long, and maintenance operation is convenient.
The utility model is to realize by following measure.
A kind of converter that is used for coke(oven)gas comprises prior art: housing, heat-resistant lining, oxygen divider, gas collector, furnace bottom threeway, coke-oven gas inlet, oxygen-rich air or pure oxygen inlet.It is characterized in that: described oxygen divider has been set up one deck corundum liner outward, and the vertex of a cone of described gas collector changes flat cover alive into.
The utility model is owing to set up one deck corundum liner outside former oxygen divider, thereby overcome the oxygen-rich air that original converter monolithc lining entered in the stove easily and dispelled, stop up the situation that oxygen-rich air or pure oxygen enter the aperture of oxygen divider, thereby make combustion distribution more even, avoid occurring burning partially and burning the situation of melting; Improved the combustion zone to the distance of catalyst layer (this distance is 1200mm～1500mm), avoided the direct contact catalyst of flame and in beds the incendiary situation, significantly improved work-ing life of conversion catalyst; Owing to change the gas collector top vertex of a cone into flat cover alive, made things convenient for the service work of converter.
To and be further described structure of the present utility model in conjunction with the accompanying drawings by embodiment below.
Description of drawings:
Fig. 1 is a structure sectional view of the present utility model.
Embodiment:
As shown in Figure 1, a kind of converter that is used for coke(oven)gas is improvements over the prior art.It comprises: housing 1, heat-resistant lining 3, oxygen divider 4, gas collector 6, furnace bottom threeway 8, coke-oven gas inlet 5, oxygen-rich air or pure oxygen inlet 2.Set up one deck corundum liner 7 outside the described oxygen divider 4, the vertex of a cone of described gas collector 6 changes flat cover alive into.
Working process of the present utility model: oxygen enrichment or pure oxygen are entered between corundum liner 7 and the oxygen divider 4 by inlet 2, enter in the stove with top coke(oven)gas inlet 5 coke(oven)gas that enter by the dispensing orifice on the oxygen divider and to burn, after enter beds and carry out conversion reaction, after collecting, gas collector 6 from furnace bottom threeway 8, discharges converter, remove synthetic ammonia or methyl alcohol, CH in the reforming gas of this moment
4Content is less than 0.5%.
Claims (2)
1, a kind of converter that is used for coke(oven)gas, comprise: housing (1), heat-resistant lining (3), oxygen divider (4), gas collector (6), furnace bottom threeway (8), coke-oven gas inlet (5), oxygen-rich air or pure oxygen inlet (2) is characterized in that: the outer one deck corundum liner (7) of having set up of described oxygen divider (4).
2, according to the described converter that is used for the coke(oven)gas conversion of claim 1, it is characterized in that: the vertex of a cone of described gas collector (6) changes flat cover alive into.
