Description
Technical field
The utility model belongs to energy-saving environmental protection device field, more particularly to a kind of blast furnace gas dehydration device.
Background technology
Blast furnace gas caused by the blast furnace of steel industry ironmaking workshop section, has certain temperature and pressure, while according to iron
The difference of ore and coke, often contain moisture, sulfur and chlorion in blast furnace gas.It is high after removing dust, gas turbine power generation
Producer gas temperature reduces, and moisture contained therein has precipitation in temperature-fall period.And produce the height of high-temperature hot-air needed for ironmaking
Stove hot-blast stove, exactly burn this~40 DEG C of BF gas heating air obtains.For the energy-conservation of hot-blast stove, generally recovery heat
The flue gas of wind furnace enters the blast furnace gas and combustion air of stove burning, and here it is double preheatings of usually said blast funnace hot blast stove
System (some are single pre-heating systems, and only warm-up combustion-supporting air or only preheat blast furnace gas).More than recovery hot-blast stove fume
The heat exchanger of heat preheating blast furnace gas, the mechanical water (water of the liquid condition of precipitation) in the presence of blast furnace gas be one more
Stubborn problem, because mechanical water, sulfur and chlorion in blast furnace gas can form the corrosion to metal heat transfer surface, and
And make it that also becoming wet ash even if a small amount of dust in blast furnace gas is adhered to heating surface, has a strong impact on heat exchange and equipment
Life-span；Meanwhile the Severe blockage of coal gas circulation passage, resistance can be caused to increase suddenly, so as to cause system shutdown.Generally, blast furnace coal
The corrosion phenomenon of large area just occurs in air preheater after using 1 year, causes heat-transfer pipe to rot to perforate, equipment can not use.
Utility model content
Technical problem：In order to solve the defects of prior art, the utility model provides one kind and significantly extends blast furnace gas
The blast furnace gas dehydration device of preheater service life.
Technical scheme：A kind of blast furnace gas dehydration device provided by the utility model, including gas piping (1), gas-liquid point
From device (2), steam pipe coil (3), water drain funnel (4)；The gas-liquid separation device (2), steam pipe coil (3) are from gas piping
(1) gas inlet (5) to gas exit (6) is set gradually；The water drain funnel (4) is located at gas piping (1) bottom, and position
Between gas inlet (5) and gas-liquid separation device (2)；The steam inlet of steam pipe coil (3) is provided with valve (9), steam disc
Manage (3) and be provided with one group of steam ejection aperture (10), steam sprays aperture (10) and faces gas-liquid separation device (2).
As an improvement, the gas-liquid separation device (2) is fixed on gas piping by gas-liquid separation device geometrical clamp (7)
(1) in.
Improved as another kind, the steam pipe coil (3) is fixed on gas piping (1) by steam pipe coil geometrical clamp (8)
It is interior.
As a further improvement, the quantity of the steam pipe coil geometrical clamp (8) is 3, it is set at 90 ° intervals.
Beneficial effect：The space that blast furnace gas dehydration device provided by the utility model occupies is minimum, simple in construction, practical
Property is good, and gas-liquid separation device can be such that blast furnace gas enters before preheater to remove mechanical water as far as possible, while periodically open steam pipe coil
On the high-temperature steam heating appropriate to coal gas that is sprayed using steam pipe coil of valve in order to avoid due to pipeline before preheater is entered
Heat loss gas temperature, which reduces, causes moisture again to separate out, and ensure that into the blast furnace gas before preheater and is free of liquid water,
Be not in liquid sulfuric acid or hydrochloric acid or and its synthesis erosion, the steam set on steam pipe coil sprays aperture and faces
Gas-liquid separation device, gas-liquid separation device can be rinsed, remove dust stratification, substantially prolongs the service life of preheater.
Brief description of the drawings
Fig. 1 is the structural representation of blast furnace gas dehydration device.
Fig. 2 is the Longitudinal cross section schematic of blast furnace gas dehydration device.
Embodiment
The utility model performance is further illustrated below.
Blast furnace gas dehydration device, see Fig. 1 and 2, including gas piping (1), gas-liquid separation device (2), steam pipe coil
(3), water drain funnel (4)；The gas-liquid separation device (2), steam pipe coil (3) are from the gas inlet (5) of gas piping (1) to coal
Gas outlet (6) is set gradually；The water drain funnel (4) is located at gas piping (1) bottom, and is located at gas inlet (5) and gas-liquid
Between separator (2)；The steam inlet of steam pipe coil (3) is provided with valve (9), and steam pipe coil (3) is provided with one group of steam
Hole (10), steam spray aperture (10) and face gas-liquid separation device (2).
The gas-liquid separation device (2) is fixed in gas piping (1) by gas-liquid separation device geometrical clamp (7).It is described
Steam pipe coil (3) is fixed in gas piping (1) by steam pipe coil geometrical clamp (8).The number of the steam pipe coil geometrical clamp (8)
Measure as 3, be set at 90 ° intervals.
The use principle of the device：
Dehydration device of the present utility model is arranged on the blast furnace gas pipeline before entering preheating；Blast furnace gas is advanced
Enter to be fixedly mounted on the gas-liquid separation device 2 of the inwall of blast furnace gas pipeline 1, gas-liquid separation device 2 covers whole blast furnace gas
Pipeline 1 so that when coal gas flows through gas-liquid separation device 2, gas passes through gas-liquid separation device 2, and liquid (mechanical water) is by gas-liquid
